The Cosmic Web Imager (CWI) --IFU And First Results  

NASA Astrophysics Data System (ADS)

We present the Cosmic Web Imager (CWI), a new integral-field spectrograph that aims to detect and map emission from the intergalactic medium (IGM) using a unique combination of instrumental techniques. First, a mirror slicer Integral Field Unit (IFU) provides spatial as well as spectral information over a wide 60 x 40 arcsec2 field of view. Volume-Phase Holographic (VPH) gratings maximize peak diffraction efficiency and allow a single grating to cover a wide bandpass. Finally, a low read-noise large format e2v CCD combined with a source/background nod-and-shuffle observing pattern controls the systematics and allows for Poisson-limited sky subtraction. Our observations of the low surface brightness universe will focus on the strong UV resonance lines of Ly? 1216, CIV 1550, and OVI 1033 redshifted over 3800-9000 Å to trace IGM at 1 < z < 7. We will showcase our IFU design as well as present first light data.

CWI and FIREBall: Two Spectrographs Built to Observe Emission from the IGM. Instrument Design and Early Results.  

NASA Astrophysics Data System (ADS)

The Cosmic Web Imager (CWI) and the Faint Intergalactic Redshifted Emission Balloon (FIREBall) are two integral field specrographs designed to investigate line emission from the intergalactic medium (predominantly Ly ?, O VI, and CIV). CWI, a ground based instrument, observes in the wavelength interval 4500 to 5400 A, while FIREBall takes advantage of a narrow stratospheric balloon window around 2000 A. The performance and design of the two instruments are discussed. Results of observations of the IGM with these new tools are presented.

Web Image Clustering  

Microsoft Academic Search

While image clustering has many important applications ranging from personal to Web image management, its use is often limited by the difficulty of extracting reliable semantics from low level image features. The image clusters can be improved by using features extracted from image regions rather than the whole image. Region segmentation can be improved in turn, by considering all images

Delivering labeled teaching images over the Web.  

PubMed Central

The Web provides educators with the best opportunity to date for distributing teaching images across the educational enterprise and within the clinical environment. Experience in the pre-Web era showed that labels and information linked to parts of the image are crucial to student learning. Standard Web technology does not enable the delivery of labeled images. We have developed an environment called OverLayer that succeeds in the authoring and delivering of such images in a variety of formats. OverLayer has a number of functional specifications, based on the literature and on our experience, among them, the following: Users should be able to find components by name or by image; to receive feedback about their choice to test themselves. The image should be of arbitrary size; should be reusable; should be linked to further information; should be stand-alone files. The labels should not obscure the image; should be linked to further information. Images should be stand-alone files that can be transferred among faculty members. Implemented in Java, OverLayer (http:/(/)omie.med.jhmi.edu/overlayer) has at its heart a set of object classes that have been reused in a number of applets for different teaching purposes and a file format for creating OverLayer images. We have created a 350-image histology library and a 500-image pathology library, and are working on a 400-image GI endoscopy library. We hope that the OverLayer suite of classes and implementations will help to further the gains made by previous image-based hyperlinked technologies. Images Figure 3

Harvesting image databases from the Web.  

PubMed

The objective of this work is to automatically generate a large number of images for a specified object class. A multimodal approach employing both text, metadata, and visual features is used to gather many high-quality images from the Web. Candidate images are obtained by a text-based Web search querying on the object identifier (e.g., the word penguin). The Webpages and the images they contain are downloaded. The task is then to remove irrelevant images and rerank the remainder. First, the images are reranked based on the text surrounding the image and metadata features. A number of methods are compared for this reranking. Second, the top-ranked images are used as (noisy) training data and an SVM visual classifier is learned to improve the ranking further. We investigate the sensitivity of the cross-validation procedure to this noisy training data. The principal novelty of the overall method is in combining text/metadata and visual features in order to achieve a completely automatic ranking of the images. Examples are given for a selection of animals, vehicles, and other classes, totaling 18 classes. The results are assessed by precision/recall curves on ground-truth annotated data and by comparison to previous approaches, including those of Berg and Forsyth and Fergus et al. PMID:21330688

Study of concrete's behavior under 4-point bending load using Coda Wave Interferometry (CWI) analysis  

NASA Astrophysics Data System (ADS)

Coda Wave Interferometry (CWI) is an ultrasonic NDT method suitable for complex material such as concrete that can precisely measure small propagation velocity variation (10-2%). By measuring variation of propagation velocity in concrete caused by acoustoelasticity phenomena, CWI analysis can be used to monitor concrete's internal stress level. For the first time, CWI is used to measure propagation velocity variations due to a stress field in a concrete beam under four-points bending test, which contains simultaneously compressive and tensile stress. Embedded optical-fiber sensors, strain gauges are used in the experiment, in order to confirm and validate the CWI analysis result. Thermocouples are also embedded into concrete beams for monitoring internal temperature fluctuations.

Landmark image super-resolution by retrieving web images.  

PubMed

This paper proposes a new super-resolution (SR) scheme for landmark images by retrieving correlated web images. Using correlated web images significantly improves the exemplar-based SR. Given a low-resolution (LR) image, we extract local descriptors from its up-sampled version and bundle the descriptors according to their spatial relationship to retrieve correlated high-resolution (HR) images from the web. Though similar in content, the retrieved images are usually taken with different illumination, focal lengths, and shot perspectives, resulting in uncertainty for the HR detail approximation. To solve this problem, we first propose aligning these images to the up-sampled LR image through a global registration, which identifies the corresponding regions in these images and reduces the mismatching. Second, we propose a structure-aware matching criterion and adaptive block sizes to improve the mapping accuracy between LR and HR patches. Finally, these matched HR patches are blended together by solving an energy minimization problem to recover the desired HR image. Experimental results demonstrate that our SR scheme achieves significant improvement compared with four state-of-the-art schemes in terms of both subjective and objective qualities. PMID:23974626

Signal flow between CWI/TOR and CWI/RAS in budding yeast under conditions of oxidative stress and glucose starvation.  

PubMed

The CWI pathway cross-talks with TOR and RAS in both the oxidative and glucose starvation responses. Mtl1 is the cell-wall protein in charge of sensing and regulating this response. Rom2 and Rho1, which are the upper elements in the pathway, mediate this signal. Several outputs are involved and required for this response, one of which, ribosomal gene expression, seems to be regulated by Sfp1, amongst other possible transcription factors. Moreover, cross-talk also occurs in a reverse flow from TOR and RAS to the CWI pathway. Thus Tor1 and Ras2 inhibition also activates Slt2 in the absence of the Mtl1 protein and assures the proper adaptive response to oxidation and glucose deprivation. PMID:21331237

Detecting image purpose in World-Wide Web documents  

NASA Astrophysics Data System (ADS)

The number of WWW documents available to users of the Internet is growing at an incredible rate. Therefore, it is becoming increasingly important to develop systems that aid users in searching, filtering, and retrieving information from the Internet. Currently, only a few prototype systems catalog and index images in Web documents. To greatly improve the cataloging and indexing of images on the Web, we have developed a prototype rule-based systems that detects the content images in Web documents. Content images are images that are associated with the main content of Web documents, as opposed to a multitude of other images that exist in Web documents for different purposes, such as decorative, advertisement and logo images. We present a system that uses decision tree learning for automated rule induction for the content images detection system. The system uses visual features, text-related features and the document context of images in concert for fast and effective content image detection in Web documents. We have evaluated the system by collecting more than 1200 images from 4 different Web sites and we have achieved an overall classification accuracy of 84 percent.

Rating of web pages based on image content analysis  

NASA Astrophysics Data System (ADS)

With the proliferation of multimedia information on the network, automatic rating of web pages becomes more and more important for web management. Obviously image analysis is very important in these kinds of tasks. But to our best knowledge, there are no publications reported on it. In this paper, we propose a novel framework to rate webpage using image content analysis. The rated categories are in compliance with the standard utilized by most web browsers like Internet Explorer, which include Normal, Revealing Attire, Exposed Breasts and Bare Buttocks. To make the rating work feasible, we analyze the images mainly using skin detection and body region, and face detection is also used as guidance for the detection of skin and body region. After that, all the results of image content analysis are integrated to achieve content rating results for web pages. We tested our system on two data sets and demonstrated its effectiveness.

Content-based image retrieval in the World Wide Web: a web agent for fetching portraits  

NASA Astrophysics Data System (ADS)

This article propose a way to automatically retrieve images from the world-wide-web using a semantic description for images and an agent concept for the retrieval of images. The system represents image in a textual way, e.g. look for a portrait of the a specific person, or fetch an image showing a countryside in Southern California. This textual descriptions are fed in search machines, e.g. yahoo, alta- vista. The resulting html documents are seeked for links. The next step subsequently processes each link by fetching the document other the net, converting it to an ascii representation, and performing a full text search by using the image description. This leads to starting points of images which are retrieved via a web-agent. The image descriptions are decomposed in a set of parts containing image operations which are further processed, e.g. a set for representing the background of a portrait tries to find a homogeneous region in the image because this is likely to find in a portrait. Additional operations are performed on the foreground, i.e. the image region which contains e.g. the face of a person. The system is realized using two C++ libraries: one for building up web-agents, LIWA++, and one for processing images, HORUS.

World Wide Web Based Image Search Engine Using Text and Image Content Features  

NASA Astrophysics Data System (ADS)

Using both text and image content features, a hybrid image retrieval system for Word Wide Web is developed in this paper. We first use a text-based image meta-search engine to retrieve images from the Web based on the text information on the image host pages to provide an initial image set. Because of the high-speed and low cost nature of the text-based approach, we can easily retrieve a broad coverage of images with a high recall rate and a relatively low precision. An image content based ordering is then performed on the initial image set. All the images are clustered into different folders based on the image content features. In addition, the images can be re-ranked by the content features according to the user feedback. Such a design makes it truly practical to use both text and image content for image retrieval over the Internet. Experimental results confirm the efficiency of the system.

Enterprise-scale image distribution with a Web PACS.  

PubMed

The integration of images with existing and new health care information systems poses a number of challenges in a multi-facility network: image distribution to clinicians; making DICOM image headers consistent across information systems; and integration of teleradiology into PACS. A novel, Web-based enterprise PACS architecture introduced at Massachusetts General Hospital provides a solution. Four AMICAS Web/Intranet Image Servers were installed as the default DICOM destination of 10 digital modalities. A fifth AMICAS receives teleradiology studies via the Internet. Each AMICAS includes: a Java-based interface to the IDXrad radiology information system (RIS), a DICOM autorouter to tape-library archives and to the Agfa PACS, a wavelet image compressor/decompressor that preserves compatibility with DICOM workstations, a Web server to distribute images throughout the enterprise, and an extensible interface which permits links between other HIS and AMICAS. Using wavelet compression and Internet standards as its native formats, AMICAS creates a bridge to the DICOM networks of remote imaging centers via the Internet. This teleradiology capability is integrated into the DICOM network and the PACS thereby eliminating the need for special teleradiology workstations. AMICAS has been installed at MGH since March of 1997. During that time, it has been a reliable component of the evolving digital image distribution system. As a result, the recently renovated neurosurgical ICU will be filmless and use only AMICAS workstations for mission-critical patient care. PMID:9735424

Following Stress Level Modification of Real Size Concrete Structures with Coda Wave Interferometry (cwi)  

NASA Astrophysics Data System (ADS)

The determination of the stress level in in-situ concrete structures is of paramount importance for in the engineering field. CODA wave interferometry (CWI) has been recently proposed to monitor stress levels in pre-stressed concrete structures in a non-destructive manner. The idea is to follow very small changes of the ultrasonic wave velocity linked to stress level modifications, through Murnaghan's theory. The change in velocity, which is of the order of 0.1% for 10 MPa for classical concrete, can be measured by taking advantage of the heterogeneity of concrete. The accurate measurement of travel time delay is made possible by a source generating a wave train with wavelength sizes comparable to that of the aggregates in the concrete, resulting in multiple scattering. This method is sufficiently sensitive to record small changes in the medium's mechanical properties. An experiment on a real size concrete structure subjected to time varying loading is described.

Design of a Web interface for anatomical images.  

PubMed

Interactive documents for use with the World Wide Web have been developed for viewing multi-dimensional radiographic and visual images of human anatomy, derived from the Visible Human Project. Emphasis has been placed on user-controlled features and selections. The purpose was to develop an interface which was independent of host operating system and browser software which would allow viewing of information by multiple users. The interfaces were implemented using HyperText Markup Language (HTML) forms, C programming language and Perl scripting language. Images were pre-processed using ANALYZE and stored on a Web server in CompuServe GIF format. Viewing options were included in the document design, such as interactive thresholding and two-dimensional slice direction. The interface is an example of what may be achieved using the World Wide Web. Key applications envisaged for such software include education, research and accessing of information through internal databases and simultaneous sharing of images by remote computers by health personnel for diagnostic purposes.

Autonomous system for Web-based microarray image analysis.  

PubMed

Software-based feature extraction from DNA microarray images still requires human intervention on various levels. Manual adjustment of grid and metagrid parameters, precise alignment of superimposed grid templates and gene spots, or simply identification of large-scale artifacts have to be performed beforehand to reliably analyze DNA signals and correctly quantify their expression values. Ideally, a Web-based system with input solely confined to a single microarray image and a data table as output containing measurements for all gene spots would directly transform raw image data into abstracted gene expression tables. Sophisticated algorithms with advanced procedures for iterative correction function can overcome imminent challenges in image processing. Herein is introduced an integrated software system with a Java-based interface on the client side that allows for decentralized access and furthermore enables the scientist to instantly employ the most updated software version at any given time. This software tool is extended from PixClust as used in Extractiff incorporated with Java Web Start deployment technology. Ultimately, this setup is destined for high-throughput pipelines in genome-wide medical diagnostics labs or microarray core facilities aimed at providing fully automated service to its users.

Web-Based Image Viewer for Monitoring High-Definition Agricultural Images  

NASA Astrophysics Data System (ADS)

This paper describes a Web-based image viewer which was developed to monitor high-definition agricultural images. In the cultivation of crops, physiological data and environmental data are important to increase crop yields. However, it is a burden for farmers to collect such data. Against this backdrop, the authors developed a monitoring system to automatically collect high-definition crop images, which can be viewed on a specialized Web-based image viewer. Users can easily observe detailed crop images over the Internet and easily find differences among the images. The authors experimentally installed the monitoring system in an apple orchard and observed the apples growing there. The system has been operating since August 11, 2009. In this paper, we confirm the ability of the monitoring system to perform detailed observations, including tracing the progress of a disease that affects the growth of an apple.

Web Service Infrastructure for Correcting InSAR Imaging  

NASA Astrophysics Data System (ADS)

InSAR images can be obtained from satellite radar data by combining signals acquired at two different times along the spacecraft's orbit, at geospatial locations nearly identical. Changes in the propagation of the radar signal from the first acquisition to the second, caused for example by changes in the tropospheric water vapor content, can lead to a deterioration of the quality of the interferometric data analysis. Other extraneous effects such as ocean tidal loading can also lead to errors that reduce the potential science return of InSAR missions. Data from Global Positioning Systems and infrared radiometers are current used on an ad hoc basis for the tropospheric corrections when available, and operational weather forecast was demonstrated to be able to fill in the remaining spatial and temporal gaps. We have developed a set of web services named OSCAR (Online Services for Correcting Atmosphere in Radar) that transparently to the user retrieves remote sensing and weather forecast data and delivers atmospheric radar delays on a latitude longitude grid that can be directly integrated with Interferometric Synthetic Aperture Radar data processing software. We will describe the common web service architecture, relying on RESTful, that we developed to streamline the development of OSCAR's capabilities. We will also discuss the Bayesian averaging process that we use for merging the radiometric data with numerical weather forecast results. Correcting for biases and estimating the error model will be discussed in detail and validation results will be presented. The success of the correction procedure will be demonstrated by using MODIS data and ECMWF model output. We will also outline the extension of our online correction system to include GPS data to automatically correct for biases in the radiometric data, and a model of ocean tidal loading to correct for long wavelength errors near coastal regions.

Robust image obfuscation for privacy protection in Web 2.0 applications  

NASA Astrophysics Data System (ADS)

We present two approaches to robust image obfuscation based on permutation of image regions and channel intensity modulation. The proposed concept of robust image obfuscation is a step towards end-to-end security in Web 2.0 applications. It helps to protect the privacy of the users against threats caused by internet bots and web applications that extract biometric and other features from images for data-linkage purposes. The approaches described in this paper consider that images uploaded to Web 2.0 applications pass several transformations, such as scaling and JPEG compression, until the receiver downloads them. In contrast to existing approaches, our focus is on usability, therefore the primary goal is not a maximum of security but an acceptable trade-off between security and resulting image quality.

A review of images of nurses and smoking on the World Wide Web.  

PubMed

With the advent of the World Wide Web, historic images previously having limited distributions are now widely available. As tobacco use has evolved, so have images of nurses related to smoking. Using a systematic search, the purpose of this article is to describe types of images of nurses and smoking available on the World Wide Web. Approximately 10,000 images of nurses and smoking published over the past century were identified through search engines and digital archives. Seven major themes were identified: nurses smoking, cigarette advertisements, helping patients smoke, "naughty" nurse, teaching women to smoke, smoking in and outside of health care facilities, and antitobacco images. The use of nursing images to market cigarettes was known but the extent of the use of these images has not been reported previously. Digital archives can be used to explore the past, provide a perspective for understanding the present, and suggest directions for the future in confronting negative images of nursing. PMID:23036793

Prototype Web-based continuing medical education using FlashPix images.  

PubMed Central

Continuing Medical Education (CME) is a requirement among practicing physicians to promote continuous enhancement of clinical knowledge to reflect new developments in medical care. Previous research has harnessed the Web to disseminate complete pathology CME case studies including history, images, diagnoses, and discussions to the medical community. Users submit real-time diagnoses and receive instantaneous feedback, eliminating the need for hard copies of case material and case evaluation forms. This project extends the Web-based CME paradigm with the incorporation of multi-resolution FlashPix images and an intuitive, interactive user interface. The FlashPix file format combines a high-resolution version of an image with a hierarchy of several lower resolution copies, providing real-time magnification via a single image file. The Web interface was designed specifically to simulate microscopic analysis, using the latest Javascript, Java and Common Gateway Interface tools. As the project progresses to the evaluation stage, it is hoped that this active learning format will provide a practical and efficacious environment for continuing medical education with additional application potential in classroom demonstrations, proficiency testing, and telepathology. Using Microsoft Internet Explorer 4.0 and above, the working prototype Web-based CME environment is accessible at http://telepathology.upmc.edu/WebInterface/NewInterface/welcome.html.

iMole, a web based image retrieval system from biomedical literature.  

PubMed

iMole is a platform that automatically extracts images and captions from biomedical literature. Images are tagged with terms contained in figure captions by means of a sophisticate text-mining tool. Moreover, iMole allows the user to upload directly their own images within the database and manually tag images by curated dictionary. Using iMole the researchers can develop a proper biomedical image database, storing the images extracted from paper of interest, image found on the web repositories, and their own experimental images. In order to show the functioning of the platform, we used iMole to build a 2DE database. Briefly, tagged 2DE gel images were collected and stored in a searchable 2DE gel database, available to users through an interactive web interface. Images were obtained by automatically parsing 16,608 proteomic publications, which yielded more than 16,500 images. The database can be further expanded by users with images of interest trough a manual uploading process. iMole is available with a preloaded set of 2DE gel data at http://imole.biodigitalvalley.com.

Cotton crop spectral imaging analysis: a web-based hyperspectral synthetic imagery simulation system  

NASA Astrophysics Data System (ADS)

The development of spectral libraries for specific vegetation species and soils is useful for identifying different physiological or physical-chemical characteristics. Usually, spectral libraries are provided as a data-base add-in of current commercial software used for analyzing hyperspectral imagery. The use of those databases requires installation of the software in the user"s machine for either visualizing or using the spectral libraries. There are also spectral libraries available on the web but the data is static and partitioned by spectrum of vegetation or soil because the size of the files of actual hyperspectral images precludes it"s publication on the web. In this paper, a web-based simulation environment for generating hyperspectral synthetic imagery of cotton plots is presented. The system was developed using Java and is based on a previous synthetic imagery program1. The mathematical and numerical formulation of the model is briefly sketched. The core computing components of the simulation environment were written in C for their computational efficiency. The emerging Java Native Interface (JNI) technique and standard Java techniques were used to design a user-friendly simulator. The simulation system provides interactive user control and real time visualization of the resulting hyperspectral image through standard web browsers. It shows potential for providing web-based hyperspectral libraries, in the form of images, for public use.

Design of a Web-tool for diagnostic clinical trials handling medical imaging research.

New clinical studies in medicine are based on patients and controls using different imaging diagnostic modalities. Medical information systems are not designed for clinical trials employing clinical imaging. Although commercial software and communication systems focus on storage of image data, they are not suitable for storage and mining of new types of quantitative data. We sought to design a Web-tool to support diagnostic clinical trials involving different experts and hospitals or research centres. The image analysis of this project is based on skeletal X-ray imaging. It involves a computerised image method using quantitative analysis of regions of interest in healthy bone and skeletal metastases. The database is implemented with ASP.NET 3.5 and C# technologies for our Web-based application. For data storage, we chose MySQL v.5.0, one of the most popular open source databases. User logins were necessary, and access to patient data was logged for auditing. For security, all data transmissions were carried over encrypted connections. This Web-tool is available to users scattered at different locations; it allows an efficient organisation and storage of data (case report form) and images and allows each user to know precisely what his task is. The advantages of our Web-tool are as follows: (1) sustainability is guaranteed; (2) network locations for collection of data are secured; (3) all clinical information is stored together with the original images and the results derived from processed images and statistical analysis that enable us to perform retrospective studies; (4) changes are easily incorporated because of the modular architecture; and (5) assessment of trial data collected at different sites is centralised to reduce statistical variance.

Web and personal image annotation by mining label correlation with relaxed visual graph embedding.  

PubMed

The number of digital images rapidly increases, and it becomes an important challenge to organize these resources effectively. As a way to facilitate image categorization and retrieval, automatic image annotation has received much research attention. Considering that there are a great number of unlabeled images available, it is beneficial to develop an effective mechanism to leverage unlabeled images for large-scale image annotation. Meanwhile, a single image is usually associated with multiple labels, which are inherently correlated to each other. A straightforward method of image annotation is to decompose the problem into multiple independent single-label problems, but this ignores the underlying correlations among different labels. In this paper, we propose a new inductive algorithm for image annotation by integrating label correlation mining and visual similarity mining into a joint framework. We first construct a graph model according to image visual features. A multilabel classifier is then trained by simultaneously uncovering the shared structure common to different labels and the visual graph embedded label prediction matrix for image annotation. We show that the globally optimal solution of the proposed framework can be obtained by performing generalized eigen-decomposition. We apply the proposed framework to both web image annotation and personal album labeling using the NUS-WIDE, MSRA MM 2.0, and Kodak image data sets, and the AUC evaluation metric. Extensive experiments on large-scale image databases collected from the web and personal album show that the proposed algorithm is capable of utilizing both labeled and unlabeled data for image annotation and outperforms other algorithms.

Web based brain volume calculation for magnetic resonance images.  

PubMed

Brain volume calculations are crucial in modern medical research, especially in the study of neurodevelopmental disorders. In this paper, we present an algorithm for calculating two classifications of brain volume, total brain volume (TBV) and intracranial volume (ICV). Our algorithm takes MRI data as input, performs several preprocessing and intermediate steps, and then returns each of the two calculated volumes. To simplify this process and make our algorithm publicly accessible to anyone, we have created a web-based interface that allows users to upload their own MRI data and calculate the TBV and ICV for the given data. This interface provides a simple and efficient method for calculating these two classifications of brain volume, and it also removes the need for the user to download or install any applications.

Improving Web image search by bag-based reranking.  

PubMed

Given a textual query in traditional text-based image retrieval (TBIR), relevant images are to be reranked using visual features after the initial text-based search. In this paper, we propose a new bag-based reranking framework for large-scale TBIR. Specifically, we first cluster relevant images using both textual and visual features. By treating each cluster as a "bag" and the images in the bag as "instances," we formulate this problem as a multi-instance (MI) learning problem. MI learning methods such as mi-SVM can be readily incorporated into our bag-based reranking framework. Observing that at least a certain portion of a positive bag is of positive instances while a negative bag might also contain positive instances, we further use a more suitable generalized MI (GMI) setting for this application. To address the ambiguities on the instance labels in the positive and negative bags under this GMI setting, we develop a new method referred to as GMI-SVM to enhance retrieval performance by propagating the labels from the bag level to the instance level. To acquire bag annotations for (G)MI learning, we propose a bag ranking method to rank all the bags according to the defined bag ranking score. The top ranked bags are used as pseudopositive training bags, while pseudonegative training bags can be obtained by randomly sampling a few irrelevant images that are not associated with the textual query. Comprehensive experiments on the challenging real-world data set NUS-WIDE demonstrate our framework with automatic bag annotation can achieve the best performances compared with existing image reranking methods. Our experiments also demonstrate that GMI-SVM can achieve better performances when using the manually labeled training bags obtained from relevance feedback. PMID:21659029

A Shape- Similarity (SS)-based method which is to effectively support a retrieval over large Chinese calligraphic manuscript databases [19]. In this retrieval method, shapes of calligraphic characters are represented by their approximate contour points extracted from the character images; 2). To speed up the retrieval efficiency, we then propose a Composite - Distance- Tree(CD-Tree)-based high-dimensional indexing scheme for it. Comprehensive experiments are conducted to testify the effectiveness and efficiency of our proposed retrieval and indexing methods respectively.

Server-based approach to web visualization of integrated 3-D medical image data.  

PubMed Central

Although computer processing power and network bandwidth are rapidly increasing, the average desktop is still not able to rapidly process large datasets such as 3-D medical image volumes. We have therefore developed a server side approach to this problem, in which a high performance graphics server accepts commands from web clients to load, process and render 3-D image volumes and models. The renderings are saved as 2-D snapshots on the server, where they are uploaded and displayed on the client. User interactions with the graphic interface on the client side are translated into additional commands to manipulate the 3-D scene, after which the server re-renders the scene and sends a new image to the client. Example forms-based and Java-based clients are described for a brain mapping application, but the techniques should be applicable to multiple domains where 3-D medical image visualization is of interest.

A medical ontology for intelligent web-based skin lesions image retrieval.  

PubMed

Researchers have applied increasing efforts towards providing formal computational frameworks to consolidate the plethora of concepts and relations used in the medical domain. In the domain of skin related diseases, the variability of semantic features contained within digital skin images is a major barrier to the medical understanding of the symptoms and development of early skin cancers. The desideratum of making these standards machine-readable has led to their formalization in ontologies. In this work, in an attempt to enhance an existing Core Ontology for skin lesion images, hand-coded from image features, high quality images were analyzed by an autonomous ontology creation engine. We show that by exploiting agglomerative clustering methods with distance criteria upon the existing ontological structure, the original domain model could be enhanced with new instances, attributes and even relations, thus allowing for better classification and retrieval of skin lesion categories from the web.

Feedstock and Web Analysis Using Mid-Infrared Diffuse Reflectance Spectroscopy and Imaging Spectroradiometry  

SciTech Connect

Potential applications of mid-infrared (MIR) spectroscopy in the forest products industry include on-line analysis of feedstock and web materials; these applications differ dramatically in purpose, speed, and overall chemical heterogeneity. Characterization of feedstock will enable sorting of the stock and/or wet chemistry adjustment prior to the web stage of paper production. Sorting will require imaging of the stock as well as classification of the wide variety of chemistry found in recycled stock. At the opposite end of the manufacturing process, on-line analysis of the web will enable adjustment of machine parameters to maximize product quality and minimize waste. Spectroscopic requirements for web analysis include high-speed capability and measurement precision. If successful, both applications could result in a reduction of resource waste, a reduction of plant pollution, and a reduction of energy use while simultaneously improving product quality. Here the progress towards feedstock and web analysis with MIR spectroscopy is presented. To date, work has progressed in three main areas: Diffuse Reflectance mid-Infrared Fourier Transform (DRIFT) spectroscopy of cellulose-based materials, chemometrics analysis, and research of MIR instrumentation for prototype development. The DRIFT spectroscopy data represents a database of the chemistries and spectroscopic signatures of interest to the applications discussed here. Over 50,000 spectra were obtained from cellulose-based materials infised with a wide variety of non-cellulose chemistry. Chemometrics analysis was performed on the DRIFT database to determine the quantitative and qualitative limits of the technique. Emphasis was placed on qualitative evaluation of spectroscopic signatures unique to the particular classes of cellulose-based material; thus, the degree to which classes could be sorted was determined. Finally, investigations of MIR instrumentation suitable for transfer of the technique from the lab-based instrument to a field ready prototype were made.

Large scale near-duplicate celebrity web images retrieval using visual and textual features.  

PubMed

Near-duplicate image retrieval is a classical research problem in computer vision toward many applications such as image annotation and content-based image retrieval. On the web, near-duplication is more prevalent in queries for celebrities and historical figures which are of particular interest to the end users. Existing methods such as bag-of-visual-words (BoVW) solve this problem mainly by exploiting purely visual features. To overcome this limitation, this paper proposes a novel text-based data-driven reranking framework, which utilizes textual features and is combined with state-of-art BoVW schemes. Under this framework, the input of the retrieval procedure is still only a query image. To verify the proposed approach, a dataset of 2 million images of 1089 different celebrities together with their accompanying texts is constructed. In addition, we comprehensively analyze the different categories of near duplication observed in our constructed dataset. Experimental results on this dataset show that the proposed framework can achieve higher mean average precision (mAP) with an improvement of 21% on average in comparison with the approaches based only on visual features, while does not notably prolong the retrieval time.

Large Scale Near-Duplicate Celebrity Web Images Retrieval Using Visual and Textual Features  

PubMed Central

Near-duplicate image retrieval is a classical research problem in computer vision toward many applications such as image annotation and content-based image retrieval. On the web, near-duplication is more prevalent in queries for celebrities and historical figures which are of particular interest to the end users. Existing methods such as bag-of-visual-words (BoVW) solve this problem mainly by exploiting purely visual features. To overcome this limitation, this paper proposes a novel text-based data-driven reranking framework, which utilizes textual features and is combined with state-of-art BoVW schemes. Under this framework, the input of the retrieval procedure is still only a query image. To verify the proposed approach, a dataset of 2 million images of 1089 different celebrities together with their accompanying texts is constructed. In addition, we comprehensively analyze the different categories of near duplication observed in our constructed dataset. Experimental results on this dataset show that the proposed framework can achieve higher mean average precision (mAP) with an improvement of 21% on average in comparison with the approaches based only on visual features, while does not notably prolong the retrieval time.

Web-based monitoring and management system for integrated enterprise-wide imaging networks  

NASA Astrophysics Data System (ADS)

Mass proliferation of IP networks and the maturity of standards has enabled the creation of sophisticated image distribution networks that operate over Intranets, Extranets, Communities of Interest (CoI) and even the public Internet. Unified monitoring, provisioning and management of such systems at the application and protocol levels represent a challenge. This paper presents a web based monitoring and management tool that employs established telecom standards for the creation of an open system that enables proactive management, provisioning and monitoring of image management systems at the enterprise level and across multi-site geographically distributed deployments. Utilizing established standards including ITU-T M.3100, and web technologies such as XML/XSLT, JSP/JSTL, and J2SE, the system allows for seamless device and protocol adaptation between multiple disparate devices. The goal has been to develop a unified interface that provides network topology views, multi-level customizable alerts, real-time fault detection as well as real-time and historical reporting of all monitored resources, including network connectivity, system load, DICOM transactions and storage capacities.

Comparing image quality of print-on-demand books and photobooks from web-based vendors  

NASA Astrophysics Data System (ADS)

Because of the emergence of e-commerce and developments in print engines designed for economical output of very short runs, there are increased business opportunities and consumer options for print-on-demand books and photobooks. The current state of these printing modes allows for direct uploading of book files via the web, printing on nonoffset printers, and distributing by standard parcel or mail delivery services. The goal of this research is to assess the image quality of print-on-demand books and photobooks produced by various Web-based vendors and to identify correlations between psychophysical results and objective metrics. Six vendors were identified for one-off (single-copy) print-on-demand books, and seven vendors were identified for photobooks. Participants rank ordered overall quality of a subset of individual pages from each book, where the pages included text, photographs, or a combination of the two. Observers also reported overall quality ratings and price estimates for the bound books. Objective metrics of color gamut, color accuracy, accuracy of International Color Consortium profile usage, eye-weighted root mean square L*, and cascaded modulation transfer acutance were obtained and compared to the observer responses. We introduce some new methods for normalizing data as well as for strengthening the statistical significance of the results. Our approach includes the use of latent mixed-effect models. We found statistically significant correlation with overall image quality and some of the spatial metrics, but correlations between psychophysical results and other objective metrics were weak or nonexistent. Strong correlation was found between psychophysical results of overall quality assessment and estimated price associated with quality. The photobook set of vendors reached higher image-quality ratings than the set of print-on-demand vendors. However, the photobook set had higher image-quality variability.

Performance of Web-based image distribution: client-oriented measurements.  

PubMed

The aim of this study was to define a clinically suitable personal computer (PC) configuration for Web-based image distribution and to assess the influence of different hard- and software configurations on the performance. Through specially developed software the time-to-display (TTD) for various PC configurations was measured. Different processor speeds, random access memory (RAM), screen resolutions, graphic adapters, network speeds, operating systems and examination types (computed radiography, CT, MRI) were evaluated, providing more than half a million measurements. Processor speed was the most relevant factor for the TTD; doubling the speed halved the TTD. Under processor speeds of 350 MHz, TTD mostly remained above 5 s for 1 CR or 16 CT images. Here Windows NT with lossy compression were superior. Processor speeds of 350 MHz and over delivered TTD <5 s. In this case Windows 2000 and lossless compression were preferable. Screen resolutions above 1280 x 1024 pixels increased the TTD mainly for CR images. The RAM amount, network speed and graphic adapter did not have a significant influence. The minimum threshold for clinical routine is any standard off-the-shelf PC better than Pentium II 350 MHz, 128 MB RAM; hence, high-end PC hardware is not required. PMID:12682783

Modeling and localization of web-based fusion image using VRML in clinical stroke case  

NASA Astrophysics Data System (ADS)

Three dimensional (3D) modeling and visualization of the brain fusion images on the World Wide Web (WWW) is an effective way of sharing anatomic and functional information of the brain over the Internet, particularly for morphometry-based research and resident training in neuroradiology and neurosurgery. In this paper, 3D modeling, visualization, dynamic manipulation techniques, and the localization techniques for obtaining distance measurements of the inside and outside of the brain are integrated in an interactive and platform-independent manner and implemented over the WWW. The T1 weighted- and diffusion-weighted MR data of a stroke case which forms the subject of this study were digitally segmented, and used to visualize VRML-fused models in the form of polygonal surfaces based on the marching cube algorithm. Also, 2D cross sectional images were sequentially displayed for the purpose of 3D volume rendering, and user interface tools were embedded with ECMA script routines for the purpose of setting the appearance and transparency of the 3D objects. Finally, a 3D measurement tool was built in order to determine the spatial positions and sizes of the 3D objects.

Cable modem access to picture archiving and communication system images using a web browser over the Internet.  

PubMed

This presentation describes our experiences using a web-based viewing software and a browser to view our picture archiving and communication system (PACS) images at a remote site with cable modem-internet communications. Our testing shows that using a cable modem to access our radiology webserver produces acceptable transmission speeds to remote sites. The average time-to-display (TTD) for 16 computed tomography (CT) images on the web-based intranet system in our hospital was 7 to 8 seconds. Using a cable modem and comparable equipment at a remote site, the average TTD is 16 seconds over the internet. The TTD does not significantly change during various hours of the day. Security for our hospital-based PACS is provided by a firewall. Access through the firewall is accomplished using virtual private network (VPN) software, a secure ID, and encryption. We have found that this is a viable method for after-hours subspecialty radiology consultation. PMID:10847372

Teleradiology network system using the web medical image conference system with a new information security solution  

NASA Astrophysics Data System (ADS)

We have developed the teleradiology network system with a new information security solution that provided with web medical image conference system. In the teleradiology network system, the security of information network is very important subjects. We are studying the secret sharing scheme and the tokenization as a method safely to store or to transmit the confidential medical information used with the teleradiology network system. The confidential medical information is exposed to the risk of the damage and intercept. Secret sharing scheme is a method of dividing the confidential medical information into two or more tallies. Individual medical information cannot be decoded by using one tally at all. Our method has the function of automatic backup. With automatic backup technology, if there is a failure in a single tally, there is redundant data already copied to other tally. Confidential information is preserved at an individual Data Center connected through internet because individual medical information cannot be decoded by using one tally at all. Therefore, even if one of the Data Centers is struck and information is damaged due to the large area disaster like the great earthquake of Japan, the confidential medical information can be decoded by using the tallies preserved at the data center to which it escapes damage. Moreover, by using tokenization, the history information of dividing the confidential medical information into two or more tallies is prevented from lying scattered by replacing the history information with another character string (Make it to powerlessness). As a result, information is available only to those who have rightful access it and the sender of a message and the message itself are verified at the receiving point. We propose a new information transmission method and a new information storage method with a new information security solution.

Computer-aided diagnosis workstation and teleradiology network system for chest diagnosis using the web medical image conference system with a new information security solution  

NASA Astrophysics Data System (ADS)

Diagnostic MDCT imaging requires a considerable number of images to be read. Moreover, the doctor who diagnoses a medical image is insufficient in Japan. Because of such a background, we have provided diagnostic assistance methods to medical screening specialists by developing a lung cancer screening algorithm that automatically detects suspected lung cancers in helical CT images, a coronary artery calcification screening algorithm that automatically detects suspected coronary artery calcification and a vertebra body analysis algorithm for quantitative evaluation of osteoporosis. We also have developed the teleradiology network system by using web medical image conference system. In the teleradiology network system, the security of information network is very important subjects. Our teleradiology network system can perform Web medical image conference in the medical institutions of a remote place using the web medical image conference system. We completed the basic proof experiment of the web medical image conference system with information security solution. We can share the screen of web medical image conference system from two or more web conference terminals at the same time. An opinion can be exchanged mutually by using a camera and a microphone that are connected with the workstation that builds in some diagnostic assistance methods. Biometric face authentication used on site of teleradiology makes "Encryption of file" and "Success in login" effective. Our Privacy and information security technology of information security solution ensures compliance with Japanese regulations. As a result, patients' private information is protected. Based on these diagnostic assistance methods, we have developed a new computer-aided workstation and a new teleradiology network that can display suspected lesions three-dimensionally in a short time. The results of this study indicate that our radiological information system without film by using computer-aided diagnosis workstation and our teleradiology network system can increase diagnostic speed, diagnostic accuracy and security improvement of medical information.

Web-based spatial analysis with the ILWIS open source GIS software and satellite images from GEONETCast  

NASA Astrophysics Data System (ADS)

This paper involves easy accessible integrated web-based analysis of satellite images with a plug-in based open source software. The paper is targeted to both users and developers of geospatial software. Guided by a use case scenario, we describe the ILWIS software and its toolbox to access satellite images through the GEONETCast broadcasting system. The last two decades have shown a major shift from stand-alone software systems to networked ones, often client/server applications using distributed geo-(web-)services. This allows organisations to combine without much effort their own data with remotely available data and processing functionality. Key to this integrated spatial data analysis is a low-cost access to data from within a user-friendly and flexible software. Web-based open source software solutions are more often a powerful option for developing countries. The Integrated Land and Water Information System (ILWIS) is a PC-based GIS & Remote Sensing software, comprising a complete package of image processing, spatial analysis and digital mapping and was developed as commercial software from the early nineties onwards. Recent project efforts have migrated ILWIS into a modular, plug-in-based open source software, and provide web-service support for OGC-based web mapping and processing. The core objective of the ILWIS Open source project is to provide a maintainable framework for researchers and software developers to implement training components, scientific toolboxes and (web-) services. The latest plug-ins have been developed for multi-criteria decision making, water resources analysis and spatial statistics analysis. The development of this framework is done since 2007 in the context of 52°North, which is an open initiative that advances the development of cutting edge open source geospatial software, using the GPL license. GEONETCast, as part of the emerging Global Earth Observation System of Systems (GEOSS), puts essential environmental data at the fingertips of users around the globe. This user-friendly and low-cost information dissemination provides global information as a basis for decision-making in a number of critical areas, including public health, energy, agriculture, weather, water, climate, natural disasters and ecosystems. GEONETCast makes available satellite images via Digital Video Broadcast (DVB) technology. An OGC WMS interface and plug-ins which convert GEONETCast data streams allow an ILWIS user to integrate various distributed data sources with data locally stored on his machine. Our paper describes a use case in which ILWIS is used with GEONETCast satellite imagery for decision making processes in Ghana. We also explain how the ILWIS software can be extended with additional functionality by means of building plug-ins and unfold our plans to implement other OGC standards, such as WCS and WPS in the same context. Especially, the latter one can be seen as a major step forward in terms of moving well-proven desktop based processing functionality to the web. This enables the embedding of ILWIS functionality in Spatial Data Infrastructures or even the execution in scalable and on-demand cloud computing environments.

[Server World-Wide Web on the Internet for the provision of clinical cases and digital radiologic images for training and continuing education in radiology].  

PubMed

The Internet, as a global computer network, provides opportunities to make available multimedia educational materials, such as teaching files and image databases, that can be accessed using "World-Wide Web" client browser to provide continuing medical education. Since August, 1995, at the Institute of Radiology-University of Palermo, we developed a World-Wide Web server on the Internet to provide a collection of interactive radiology educational resources such as teaching files and image database for continuing medical education in radiology. Our server is based on a UNIX workstation connected to the Internet via our campus Ethernet network and reachable at the uniform resource locator (URL) address: http:/(/)mbox.unipa.it/approximately radpa/ radpa.html. Digital CT and MR images for teaching files and image database are downloaded through an Ethernet local area network from a GE Advantage Windows workstation. US images will be acquired on-line through a video digitizing board. Radiographs will be digitized by means of a Charge Coupled Device (CCD) scanner. To set up teaching files, image database and all other documents, we use the standard "HyperText Markup Language" (HTML) to edit the documents, and the Graphics Interchange Format (GIF) or Joint Photographic Expert Group (JPEG) format to store the images. Nine teaching files are presently available on the server, together with 49 images in the database, a list of international radiological servers, a section devoted to the museum of radiology hosted by our Institute, the electronic version of the Journal Eido Electa. In the first 12 months of public access through the Internet, 12,280 users accessed the server worldwide: 45% of them to retrieve teaching files; 35% to retrieve images from the database; the remaining 20% to retrieve other documents. Placing teaching files and image database on a World-Wide Web server makes these cases more available to residents and radiologists to provide continuing medical education in radiology. PMID:9411524

Foibles, follies, and fusion: web-based collaboration for medical image labeling.  

PubMed

Labels that identify specific anatomical and functional structures within medical images are essential to the characterization of the relationship between structure and function in many scientific and clinical studies. Automated methods that allow for high throughput have not yet been developed for all anatomical targets or validated for exceptional anatomies, and manual labeling remains the gold standard in many cases. However, manual placement of labels within a large image volume such as that obtained using magnetic resonance imaging (MRI) is exceptionally challenging, resource intensive, and fraught with intra- and inter-rater variability. The use of statistical methods to combine labels produced by multiple raters has grown significantly in popularity, in part, because it is thought that by estimating and accounting for rater reliability estimates of the true labels will be more accurate. This paper demonstrates the performance of a class of these statistical label combination methodologies using real-world data contributed by minimally trained human raters. The consistency of the statistical estimates, the accuracy compared to the individual observations, and the variability of both the estimates and the individual observations with respect to the number of labels are presented. It is demonstrated that statistical fusion successfully combines label information using data from online (Internet-based) collaborations among minimally trained raters. This first successful demonstration of a statistically based approach using minimally trained raters opens numerous possibilities for very large scale efforts in collaboration. Extension and generalization of these technologies for new applications will certainly present fascinating areas for continuing research. PMID:21839181

Web Weavers  

NSDL National Science Digital Library

In this outdoor science/art activity, learners investigate spider webs by using string to create their own spider webs. Before making their own web models, learners look closely at spider webs in nature, using a water mist sprayer to make real webs more visible in their natural setting. Learners also consider the spiders and other animals they spot on or very near real webs. (In case of rain, this activity can be done in an old shed, garage or shelter where spider webs are found.)

Web It!  

NSDL National Science Digital Library

In this outdoor activity, learners investigate spider webs and feeding behavior, particularly how spiders trap food in their sticky silk webs while not getting stuck themselves. Learners catch small insects and drop them into webs they have found, then watch what the spiders do to approach an insect and prepare it for eating. This activity goes well with Web Weavers from the same source, and is a good night activity because spiders are nocturnal animals.

Four-dimensional characterization of a sheet-forming web  

DOEpatents

A method and apparatus are provided by which a sheet-forming web may be characterized in four dimensions. Light images of the web are recorded at a point adjacent the initial stage of the web, for example, near the headbox in a paperforming operation. The images are digitized, and the resulting data is processed by novel algorithms to provide a four-dimensional measurement of the web. The measurements include two-dimensional spatial information, the intensity profile of the web, and the depth profile of the web. These measurements can be used to characterize the web, predict its properties and monitor production events, and to analyze and quantify headbox flow dynamics.

WebMIRS: web-based medical information retrieval system  

NASA Astrophysics Data System (ADS)

At the Lister Hill National Center for Biomedical Communications, a research and development division of the National Library of Medicine (NLM), we are developing a prototype multimedia database system to provide World Wide Web access to biomedical databases. WebMIRS (Web-based Medical Information Retrieval System) will allow access to databases containing text and images and will allow database query by standard SQL, by image content, or by a combination of the two. The system is being developed in the form of Java applets, which will communicate with the Informix DBMS on an NLM Sun workstation running the Solaris operating system. The system architecture will allow access from any hardware platform, which supports a Java-enabled Web browser, such as Netscape or Internet Explorer. Initial databases will include data from two national health surveys conducted by the National Center for Health Statistics (NCHS), and will include x-ray images from those surveys. In addition to describing in- house research in database access systems, this paper describes ongoing work toward querying by image content. Image content search capability will include capability to search for x-ray images similar to an input image with respect to vertebral morphometry used to characterize features such as fractures and disc space narrowing.

IDL Grid Web Portal  

NASA Astrophysics Data System (ADS)

Image Data Language is a software for data analysis, visualization and cross-platform application development. The potentiality of IDL is well-known in the academic scientific world, especially in the astronomical environment where thousands of procedures are developed by using IDL. The typical use of IDL is the interactive mode but it is also possible to run IDL programs that do not require any interaction with the user, submitting them in batch or background modality. Through the interactive mode the user immediately receives images or other data produced in the running phase of the program; in batch or background mode, the user will have to wait for the end of the program, sometime for many hours or days to obtain images or data that IDL produced as output: in fact in Grid environment it is possible to access to or retrieve data only after completion of the program. The work that we present gives flexibility to IDL procedures submitted to the Grid computer infrastructure. For this purpose we have developed an IDL Grid Web Portal to allow the user to access the Grid and to submit IDL programs granting a full job control and the access to images and data generated during the running phase, without waiting for their completion. We have used the PHP technology and we have given the same level of security that Grid normally offers to its users. In this way, when the user notices that the intermediate program results are not those expected, he can stop the job, change the parameters to better satisfy the computational algorithm and resubmit the program, without consuming the CPU time and other Grid resources. The IDL Grid Web Portal allows you to obtain IDL generated images, graphics and data tables by using a normal browser. All conversations from the user and the Grid resources occur via Web, as well as authentication phases. The IDL user has not to change the program source much because the Portal will automatically introduce the appropriate modification before submitting the IDL program to the Grid. When the user wishes, he will be able to check the status of his program and outputs, if any, because the Portal will assign the users a specific and univocal session identification number. This Web portal runs in the Trinacria Grid Virtual Laboratory and fully exploits the power of this grid in terms of CPU and data storage.

Sequential detection of web defects  

DOEpatents

A system for detecting defects on a moving web having a sequential series of identical frames uses an imaging device to form a real-time camera image of a frame and a comparitor to comparing elements of the camera image with corresponding elements of an image of an exemplar frame. The comparitor provides an acceptable indication if the pair of elements are determined to be statistically identical; and a defective indication if the pair of elements are determined to be statistically not identical. If the pair of elements is neither acceptable nor defective, the comparitor recursively compares the element of said exemplar frame with corresponding elements of other frames on said web until one of the acceptable or defective indications occur.

Automating Information Discovery Within the Invisible Web  

NASA Astrophysics Data System (ADS)

A Web crawler or spider crawls through the Web looking for pages to index, and when it locates a new page it passes the page on to an indexer. The indexer identifies links, keywords, and other content and stores these within its database. This database is searched by entering keywords through an interface and suitable Web pages are returned in a results page in the form of hyperlinks accompanied by short descriptions. The Web, however, is increasingly moving away from being a collection of documents to a multidimensional repository for sounds, images, audio, and other formats. This is leading to a situation where certain parts of the Web are invisible or hidden. The term known as the "Deep Web" has emerged to refer to the mass of information that can be accessed via the Web but cannot be indexed by conventional search engines. The concept of the Deep Web makes searches quite complex for search engines. Google states that the claim that conventional search engines cannot find such documents as PDFs, Word, PowerPoint, Excel, or any non-HTML page is not fully accurate and steps have been taken to address this problem by implementing procedures to search items such as academic publications, news, blogs, videos, books, and real-time information. However, Google still only provides access to a fraction of the Deep Web. This chapter explores the Deep Web and the current tools available in accessing it.

Development and Implementation of a Web-Enabled 3D Consultation Tool for Breast Augmentation Surgery Based on 3D-Image Reconstruction of 2D Pictures  

PubMed Central

Background Producing a rich, personalized Web-based consultation tool for plastic surgeons and patients is challenging. Objective (1) To develop a computer tool that allows individual reconstruction and simulation of 3-dimensional (3D) soft tissue from ordinary digital photos of breasts, (2) to implement a Web-based, worldwide-accessible preoperative surgical planning platform for plastic surgeons, and (3) to validate this tool through a quality control analysis by comparing 3D laser scans of the patients with the 3D reconstructions with this tool from original 2-dimensional (2D) pictures of the same patients. Methods The proposed system uses well-established 2D digital photos for reconstruction into a 3D torso, which is then available to the user for interactive planning. The simulation is performed on dedicated servers, accessible via Internet. It allows the surgeon, together with the patient, to previsualize the impact of the proposed breast augmentation directly during the consultation before a surgery is decided upon. We retrospectively conduced a quality control assessment of available anonymized pre- and postoperative 2D digital photographs of patients undergoing breast augmentation procedures. The method presented above was used to reconstruct 3D pictures from 2D digital pictures. We used a laser scanner capable of generating a highly accurate surface model of the patient’s anatomy to acquire ground truth data. The quality of the computed 3D reconstructions was compared with the ground truth data used to perform both qualitative and quantitative evaluations. Results We evaluated the system on 11 clinical cases for surface reconstructions and 4 clinical cases of postoperative simulations, using laser surface scan technologies showing a mean reconstruction error between 2 and 4 mm and a maximum outlier error of 16 mm. Qualitative and quantitative analyses from plastic surgeons demonstrate the potential of these new emerging technologies. Conclusions We tested our tool for 3D, Web-based, patient-specific consultation in the clinical scenario of breast augmentation. This example shows that the current state of development allows for creation of responsive and effective Web-based, 3D medical tools, even with highly complex and time-consuming computation, by off-loading them to a dedicated high-performance data center. The efficient combination of advanced technologies, based on analysis and understanding of human anatomy and physiology, will allow the development of further Web-based reconstruction and predictive interfaces at different scales of the human body. The consultation tool presented herein exemplifies the potential of combining advancements in the core areas of computer science and biomedical engineering with the evolving areas of Web technologies. We are confident that future developments based on a multidisciplinary approach will further pave the way toward personalized Web-enabled medicine.

Animal Diversity Web  

NSDL National Science Digital Library

The University of Michigan Museum of Zoology provides the searchable Animal Diversity Web database, with species accounts (images and text) of some of the world's mammals, birds, amphibians, reptiles, sharks, bony fishes, mollusks, arthropods and echinoderms. The database is searchable by common or scientific name. For each species account, information includes scientific and common name, classification (Phylum through Genus), and color photographs (many beauties). Some accounts supply additional information, such as geographic range, physical characteristics, natural history (food habits, reproduction, behavior, conservation, and habitat), other comments, and references. Although the list of species is by no means complete, these simple but effective accounts are interesting to read and will be helpful as supplemental resources in a biological diversity/ ecology course.

Presence of pro-tobacco messages on the Web.  

PubMed

Ignored in the finalized Master Settlement Agreement (National Association of Attorneys General, 1998), the unmonitored, unregulated World Wide Web (Web) can operate as a major vehicle for delivering pro-tobacco messages, images, and products to millions of young consumers. A content analysis of 318 randomly sampled pro-tobacco Web sites revealed that tobacco has a pervasive presence on the Web, especially on e-commerce sites and sites featuring hobbies, recreation, and "fetishes." Products can be ordered online on nearly 50% of the sites, but only 23% of the sites included underage verification. Further, only 11% of these sites contain health warnings. Instead, pro-tobacco sites frequently associate smoking with "glamorous" and "alternative" lifestyles, and with images of young males and young (thin, attractive) females. Finally, many of the Web sites offered interactive site features that are potentially appealing to young Web users. Recommendations for future research and counterstrategies are discussed.

Drying of fiber webs  

DOEpatents

A process and an apparatus for high-intensity drying of fiber webs or sheets, such as newsprint, printing and writing papers, packaging paper, and paperboard or linerboard, as they are formed on a paper machine. The invention uses direct contact between the wet fiber web or sheet and various molten heat transfer fluids, such as liquified eutectic metal alloys, to impart heat at high rates over prolonged durations, in order to achieve ambient boiling of moisture contained within the web. The molten fluid contact process causes steam vapor to emanate from the web surface, without dilution by ambient air; and it is differentiated from the evaporative drying techniques of the prior industrial art, which depend on the uses of steam-heated cylinders to supply heat to the paper web surface, and ambient air to carry away moisture, which is evaporated from the web surface. Contact between the wet fiber web and the molten fluid can be accomplished either by submersing the web within a molten bath or by coating the surface of the web with the molten media. Because of the high interfacial surface tension between the molten media and the cellulose fiber comprising the paper web, the molten media does not appreciately stick to the paper after it is dried. Steam generated from the paper web is collected and condensed without dilution by ambient air to allow heat recovery at significantly higher temperature levels than attainable in evaporative dryers.

Web Accessibility and Guidelines  

NASA Astrophysics Data System (ADS)

Access to, and movement around, complex online environments, of which the World Wide Web (Web) is the most popular example, has long been considered an important and major issue in the Web design and usability field. The commonly used slang phrase ‘surfing the Web’ implies rapid and free access, pointing to its importance among designers and users alike. It has also been long established that this potentially complex and difficult access is further complicated, and becomes neither rapid nor free, if the user is disabled. There are millions of people who have disabilities that affect their use of the Web. Web accessibility aims to help these people to perceive, understand, navigate, and interact with, as well as contribute to, the Web, and thereby the society in general. This accessibility is, in part, facilitated by the Web Content Accessibility Guidelines (WCAG) currently moving from version one to two. These guidelines are intended to encourage designers to make sure their sites conform to specifications, and in that conformance enable the assistive technologies of disabled users to better interact with the page content. In this way, it was hoped that accessibility could be supported. While this is in part true, guidelines do not solve all problems and the new WCAG version two guidelines are surrounded by controversy and intrigue. This chapter aims to establish the published literature related to Web accessibility and Web accessibility guidelines, and discuss limitations of the current guidelines and future directions.

The urologic epithelial stem cell database (UESC) - a web tool for cell type-specific gene expression and immunohistochemistry images of the prostate and bladder  

PubMed Central

Background Public databases are crucial for analysis of high-dimensional gene and protein expression data. The Urologic Epithelial Stem Cells (UESC) database is a public database that contains gene and protein information for the major cell types of the prostate, prostate cancer cell lines, and a cancer cell type isolated from a primary tumor. Similarly, such information is available for urinary bladder cell types. Description Two major data types were archived in the database, protein abundance localization data from immunohistochemistry images, and transcript abundance data principally from DNA microarray analysis. Data results were organized in modules that were made to operate independently but built upon a core functionality. Gene array data and immunostaining images for human and mouse prostate and bladder were made available for interrogation. Data analysis capabilities include: (1) CD (cluster designation) cell surface protein data. For each cluster designation molecule, a data summary allows easy retrieval of images (at multiple magnifications). (2) Microarray data. Single gene or batch search can be initiated with Affymetrix Probeset ID, Gene Name, or Accession Number together with options of coalescing probesets and/or replicates. Conclusion Databases are invaluable for biomedical research, and their utility depends on data quality and user friendliness. UESC provides for database queries and tools to examine cell type-specific gene expression (normal vs. cancer), whereas most other databases contain only whole tissue expression datasets. The UESC database provides a valuable tool in the analysis of differential gene expression in prostate cancer genes in cancer progression.

Sign language Web pages.  

PubMed

The WORLD WIDE WEB has changed the way people interact. It has also become an important equalizer of information access for many social sectors. However, for many people, including some sign language users, Web accessing can be difficult. For some, it not only presents another barrier to overcome but has left them without cultural equality. The present article describes a system that allows sign language-only Web pages to be created and linked through a video-based technique called sign-linking. In two studies, 14 Deaf participants examined two iterations of signlinked Web pages to gauge the usability and learnability of a signing Web page interface. The first study indicated that signing Web pages were usable by sign language users but that some interface features required improvement. The second study showed increased usability for those features; users consequently couldnavigate sign language information with ease and pleasure. PMID:17225637

A query integrator and manager for the query web.  

PubMed

We introduce two concepts: the Query Web as a layer of interconnected queries over the document web and the semantic web, and a Query Web Integrator and Manager (QI) that enables the Query Web to evolve. QI permits users to write, save and reuse queries over any web accessible source, including other queries saved in other installations of QI. The saved queries may be in any language (e.g. SPARQL, XQuery); the only condition for interconnection is that the queries return their results in some form of XML. This condition allows queries to chain off each other, and to be written in whatever language is appropriate for the task. We illustrate the potential use of QI for several biomedical use cases, including ontology view generation using a combination of graph-based and logical approaches, value set generation for clinical data management, image annotation using terminology obtained from an ontology web service, ontology-driven brain imaging data integration, small-scale clinical data integration, and wider-scale clinical data integration. Such use cases illustrate the current range of applications of QI and lead us to speculate about the potential evolution from smaller groups of interconnected queries into a larger query network that layers over the document and semantic web.

A Query Integrator and Manager for the Query Web  

PubMed Central

We introduce two concepts: the Query Web as a layer of interconnected queries over the document web and the semantic web, and a Query Web Integrator and Manager (QI) that enables the Query Web to evolve. QI permits users to write, save and reuse queries over any web accessible source, including other queries saved in other installations of QI. The saved queries may be in any language (e.g. SPARQL, XQuery); the only condition for interconnection is that the queries return their results in some form of XML. This condition allows queries to chain off each other, and to be written in whatever language is appropriate for the task. We illustrate the potential use of QI for several biomedical use cases, including ontology view generation using a combination of graph-based and logical approaches, value set generation for clinical data management, image annotation using terminology obtained from an ontology web service, ontology-driven brain imaging data integration, small-scale clinical data integration, and wider-scale clinical data integration. Such use cases illustrate the current range of applications of QI and lead us to speculate about the potential evolution from smaller groups of interconnected queries into a larger query network that layers over the document and semantic web.

Web-based radiology applications for clinicians and radiologists  

NASA Astrophysics Data System (ADS)

The University of Pennsylvania Radiology Department has developed a suite of Web based applications for clinicians and radiologists to provide wide spread, cost-effective and easy access to radiological information. The Image Viewer application provides clinicians and radiologists access to all diagnostic reports and digital images performed in the last week for all Emergency Dept., Intensive Care Unit and Neuro/CT studies. Image control options including zoom/pan, rotate, flip, and window/level are all available. The image mover/viewer application gives radiologists and technologists the ability to both move studies between any DICOM Storage Class Provider (SCP) and DICOM storage class user (SCU) and to view studies from any DICOM displayed. Web server support requires integration using Perl based CGI scripts with our DICOM/PACS and the MIR/CTN for images and our IDXrad/RIS for reports. Targeted images and reports are automatically routed from the PACS and RIS for storage on the web server. All images sent to the web server are modality specific per-processed to reduce size and improve contrast. After processing, all images are stored in DICOM and GIF formats. Client support requires web browsers with JavaScript and frame support.

A Web Portal that Enables Collaborative Use of Advanced Medical Image Processing and Informatics Tools through the Biomedical Informatics Research Network (BIRN)  

PubMed Central

Launched in 2001, the Biomedical Informatics Research Network (BIRN; http://www.nbirn.net) is an NIH – NCRR initiative that enables researchers to collaborate in an environment for biomedical research and clinical information management, focused particularly upon medical imaging. Although it supports a vast array of programs to transform and calculate upon medical images, three fundamental problems emerged that inhibited collaborations. The first was that the complexity of the programs, and at times legal restrictions, combined to prohibit these programs from being accessible to all members of the teams and indeed the general researcher, although this was a fundamental mission of the BIRN. Second, the calculations that needed to be performed were very complex, and required many steps that often needed to be performed by different groups. Third, many of the analysis programs were not interoperable. These problems combined to created tremendous logistical problems. The solution was to create a portal-based workflow application that allowed the complex, collaborative tasks to take place and enabled new kinds of calculations that had not previously been practical.

A framework for medical visual information exchange on the web.  

PubMed

The web has become such an extensive health information repository in the world that it is increasingly difficult to search for relevant medical information. Most medical information available on the web is not peer reviewed, and is retrieved imprecisely by current web search mechanisms (i.e. based on keywords). This paper presents the MedISeek metadata model that allows one to describe medical visual information (i.e. medical images) of different modalities, including their properties, components, relationships and authorship. The model uses the web architecture and supports the international classification of diseases and related health problems (i.e. ICD-10). An RDF schema (Resource Description Framework (RDF), http://www.w3.org/RDF/.) derived from this metadata model is integrated to each medical image, and specifies the semantics of each property in the image. Thus, relevant information can be extracted directly from the images, and data integrity is better preserved in the web. A prototype, presented here, has been built to validate the metadata model, and the mechanism for medical visual information exchange on the web. Our preliminary experimental results indicate that authorized users of our system have been able to describe, store and retrieve medical images and their associated diagnostic information.

Chapter 59: Web Services  

NASA Astrophysics Data System (ADS)

Web services are a cornerstone of the distributed computing infrastructure that the VO is built upon yet to the newcomer, they can appear to be a black art. This perception is not helped by the miasma of technobabble that pervades the subject and the seemingly impenetrable high priesthood of actual users. In truth, however, there is nothing conceptually difficult about web services (unsurprisingly any complexities will lie in the implementation details) nor indeed anything particularly new. A web service is a piece of software available over a network with a formal description of how it is called and what it returns that a computer can understand. Note that entities such as web servers, ftp servers and database servers do not generally qualify as they lack the standardized description of their inputs and outputs. There are prior technologies, such as RMI, CORBA, and DCOM, that have employed a similar approach but the success of web services lies predominantly in its use of standardized XML to provide a language-neutral way for representing data. In fact, the standardization goes further as web services are traditionally (or as traditionally as five years will allow) tied to a specific set of technologies (WSDL and SOAP conveyed using HTTP with an XML serialization). Alternative implementations are becoming increasingly common and we will cover some of these here. One important thing to remember in all of this, though, is that web services are meant for use by computers and not humans (unlike web pages) and this is why so much of it seems incomprehensible gobbledegook. In this chapter, we will start with an overview of the web services current in the VO and present a short guide on how to use and deploy a web service. We will then review the different approaches to web services, particularly REST and SOAP, and alternatives to XML as a data format. We will consider how web services can be formally described and discuss how advanced features such as security, state and asynchrony can be provided. Note that much of this material is not yet used in the VO but features heavily in IVOA discussions on advanced services and capabilities.

A web-based virtual lighting simulator  

SciTech Connect

This paper is about a web-based ''virtual lighting simulator,'' which is intended to allow architects and lighting designers to quickly assess the effect of key parameters on the daylighting and lighting performance in various space types. The virtual lighting simulator consists of a web-based interface that allows navigation through a large database of images and data, which were generated through parametric lighting simulations. At its current form, the virtual lighting simulator has two main modules, one for daylighting and one for electric lighting. The daylighting module includes images and data for a small office space, varying most key daylighting parameters, such as window size and orientation, glazing type, surface reflectance, sky conditions, time of the year, etc. The electric lighting module includes images and data for five space types (classroom, small office, large open office, warehouse and small retail), varying key lighting parameters, such as the electric lighting system, surface reflectance, dimming/switching, etc. The computed images include perspectives and plans and are displayed in various formats to support qualitative as well as quantitative assessment. The quantitative information is in the form of iso-contour lines superimposed on the images, as well as false color images and statistical information on work plane illuminance. The qualitative information includes images that are adjusted to account for the sensitivity and adaptation of the human eye. The paper also includes a section on the major technical issues and their resolution.

A zooming Web browser  

SciTech Connect

We are developing a prototype zooming World-Wide Web browser within Pad++, a multiscale graphical environment. Instead of having a single page visible at a time, multiple pages and the links between them are depicted on a large zoomable information surface. Pages are scaled so that the page in focus is clearly readable with connected pages shown at smaller scales to provide context. We quantitatively compared performance with the Pad++ Web browser and Netscape in several different scenarios. We examined how quickly users could answer questions about a specific Web site designed for this test. Initially we found that subjects answered questions slightly slower with Pad++ than with Netscape. After analyzing the results of this study, we implemented several changes to the Pad++ Web browser, and repeated one Pad++ condition. After improvements were made to the Pad++ browser, subjects using Pad++ answered questions 23% faster than those using Netscape.

Supporting Web Search with Visualization  

NASA Astrophysics Data System (ADS)

One of the fundamental goals of Web-based support systems is to promote and support human activities on the Web. The focus of this Chapter is on the specific activities associated with Web search, with special emphasis given to the use of visualization to enhance the cognitive abilities of Web searchers. An overview of information retrieval basics, along with a focus on Web search and the behaviour of Web searchers is provided. Information visualization is introduced as a means for supporting users as they perform their primary Web search tasks. Given the challenge of visualizing the primarily textual information present in Web search, a taxonomy of the information that is available to support these tasks is given. The specific challenges of representing search information are discussed, and a survey of the current state-of-the-art in visual Web search is introduced. This Chapter concludes with our vision for the future of Web search.

U.S. Geological Survey Presents: The Learning Web  

NSDL National Science Digital Library

The Learning Web, provided by the U.S. Geological Survey, is dedicated to K-12 education, exploration, and life-long learning. It is divided into two sections, Teaching in the Learning Web, and Living in the Learning Web. Teaching at present contains information about three main topics, Global Change, Working with Maps, and Earth Science. Each of these sections offers student activities, along with several images. Global Change and Working with Maps also offer teacher's guides that contain bibliographies and further information. Teaching also contains pointers to lists of USGS maintained pointers (not limited to K-12 sites) in subjects such as climate, earth science, hydrology, oceanography, and volcanology, among others. Living in the Learning Web presents information on topics such as household water supply, radon gas, preparing for volcanoes, and the affect of weather on streams. Each one of these sections connects to a pertinent USGS Web page, which in turn offers additional information and pointers.

Web-accessible cervigram automatic segmentation tool

Uterine cervix image analysis is of great importance to the study of uterine cervix cancer, which is among the leading cancers affecting women worldwide. In this paper, we describe our proof-of-concept, Web-accessible system for automated segmentation of significant tissue regions in uterine cervix images, which also demonstrates our research efforts toward promoting collaboration between engineers and physicians for medical image analysis projects. Our design and implementation unifies the merits of two commonly used languages, MATLAB and Java. It circumvents the heavy workload of recoding the sophisticated segmentation algorithms originally developed in MATLAB into Java while allowing remote users who are not experienced programmers and algorithms developers to apply those processing methods to their own cervicographic images and evaluate the algorithms. Several other practical issues of the systems are also discussed, such as the compression of images and the format of the segmentation results.

A New Web Interface for Saada  

NASA Astrophysics Data System (ADS)

Saada transforms a set of heterogeneous FITS files or VOTables of various categories (images, tables, spectra, etc.) in a powerful database deployed on the Web without writing code. Saada can mix data of various categories in multiple collections. Data collections can each be linked to others, making relevant browsing paths and allowing data-mining oriented queries. Saada supports 4 VO services (spectra, images, sources and TAP). Data collections can be published immediately after the deployment of the Web interface. The poster presents the new the administration interface (beta) coming with Saada databases. This application is much more user-friendly. It also makes the publication of data collections into the VO very easy.

Digital Imaging and Image Processing  

NSDL National Science Digital Library

The first site is an excellent introduction to digital imaging from the Eastman Kodak Company (1). There are five lessons with review questions and competency exams, covering fundamentals, image capture, and processing. A more technical introduction is found at the Digital Imaging Glossary (2). This educational resource has several short articles about compression algorithms and specific imaging techniques. The Hypermedia Image Processing Reference (3) goes into the theory of image processing. It describes operations involving image arithmetic, blending multiple images, and feature detectors, to name a few; and several of the sections have illustrative Java applets. The Center for Imaging Science at John Hopkins University (4) offers two chapters from a book on "metric pattern theory." A brief overview of the material is provided on the main page, and the chapters can be viewed on or offline with special plug-ins given on the Web site. The Journal of Electronic Imaging (5) is a quarterly publication with many papers on current research. The final issue of 2002 has a special section on Internet imaging that is quite interesting. A research project at the University of Washington (6) focuses on the role of mathematics in image processing. Besides a thorough description of the project, there is free software and documentation given on the Web site. Philips Research (7) is working on a product that seems like something from a science fiction movie. Three dimensional television and the technologies that make it possible are described on the site. Related to this is a November 2002 news article discussing holograms and 3-D video displays (8). The devices are being studied by the Spatial Imaging Group at the Massachusetts Institute of Technology Media Lab.

The Learning Web  

NSDL National Science Digital Library

Here is a new, rich resource for K-12 teachers and students from the US Geological Survey (USGS). The Learning Web provides online lesson plans, activities, tutorials (some downloadable and printable in .pdf), and links to references dealing with interdisciplinary studies of natural science. For example, the Exploring Caves section (1-3 level) covers the basic geology of caves, life habits of cave-dwelling organisms, and cave safety and conservation. Other topics explored on the Learning Web include maps, climate, wildlife, earth processes, and more. Learning Web culls pages appropriate for K-12 instruction from the USGS's vast online collection of factsheets, data, and program sites, allowing teachers and students to spend time learning rather than searching. However, because this site is so full of information, it can be tricky to navigate and important sections can be missed, so try using their search engine to find specific topics. Note also that elementary content is much more abundant here than secondary.

Using ESO Reflex with Web Services  

NASA Astrophysics Data System (ADS)

ESO Reflex is a prototype graphical workflow system, based on Taverna, and primarily intended to be a flexible way of running ESO data reduction recipes along with other legacy applications and user-written tools. ESO Reflex can also readily use the Taverna Web Services features that are based on the Apache Axis SOAP implementation. Taverna is a general purpose Web Service client, and requires no programming to use such services. However, Taverna also has some restrictions: for example, no numerical types such integers. In addition the preferred binding style is document/literal wrapped, but most astronomical services publish the Axis default WSDL using RPC/encoded style. Despite these minor limitations we have created simple but very promising test VO workflow using the Sesame name resolver service at CDS Strasbourg, the Hubble SIAP server at the Multi-Mission Archive at Space Telescope (MAST) and the WESIX image cataloging and catalogue cross-referencing service at the University of Pittsburgh. ESO Reflex can also pass files and URIs via the PLASTIC protocol to visualisation tools and has its own viewer for VOTables. We picked these three Web Services to try to set up a realistic and useful ESO Reflex workflow. They also demonstrate ESO Reflex abilities to use many kind of Web Services because each of them requires a different interface. We describe each of these services in turn and comment on how it was used

NASA Astrophysics Data System (ADS)

We analyze the effectiveness of different Web browser update mechanisms on various operating systems; from Google Chrome's silent update mechanism to Opera's update requiring a full re-installation. We use anonymized logs from Google's world wide distributed Web servers. An analysis of the logged HTTP user-agent strings that Web browsers report when requesting any Web page is used to measure the daily browser version shares in active use. To the best of our knowledge, this is the first global scale measurement of Web browser update effectiveness comparing four different Web browser update strategies including Google Chrome. Our measurements prove that silent updates and little dependency on the underlying operating system are most effective to get users of Web browsers to surf the Web with the latest browser version.

Quantum computational webs  

SciTech Connect

We discuss the notion of quantum computational webs: These are quantum states universal for measurement-based computation, which can be built up from a collection of simple primitives. The primitive elements--reminiscent of building blocks in a construction kit--are (i) one-dimensional states (computational quantum wires) with the power to process one logical qubit and (ii) suitable couplings, which connect the wires to a computationally universal web. All elements are preparable by nearest-neighbor interactions in a single pass, of the kind accessible in a number of physical architectures. We provide a complete classification of qubit wires, a physically well-motivated class of universal resources that can be fully understood. Finally, we sketch possible realizations in superlattices and explore the power of coupling mechanisms based on Ising or exchange interactions.

Online advertising has enjoyed exponential growth in recent years, and many advertisements appear in the form of images. Although it makes considerable profit, these advertisements tend to disturb the Internet surfing of normal users. Moreover, they always bring extra burden in indexing to commercial image search engines. Therefore, it is necessary to automatically detect those advertising images on the Web.

Hera: Engineering Web Applications Using Semantic Web-based Models  

NASA Astrophysics Data System (ADS)

In this chapter, we consider the contribution of models and model-driven approaches based on Semantic Web for the development of Web applications. The model-driven web engineering approach, that separates concerns on different abstraction level in the application design process, allows for more robust and structural design of web applications. This is illustrated by the use of Hera, an approach from the class of Web engineering methods that relies on models expressed using RDF(S) and an RDF(S) query language. It illustrates how models and in particular models that fit with the ideas and concepts from the Semantic Web allow to approach the design and engineering of modern, open and heterogeneous Web based systems. In the presented approach, adaptation and personalization are a main aspect and it is illustrated how they are expressed using semantic data models and languages. Also specific features of Hera are discussed, like interoperability between applications in user modeling, aspect orientation in Web design and graphical tool support for Web application design.

WebPresent: a World Wide Web-based telepresentation tool for physicians  

NASA Astrophysics Data System (ADS)

In this paper, we present the design architecture and the implementation status of WebPresent - a world wide web based tele-presentation tool. This tool allows a physician to use a conference server workstation and make a presentation of patient cases to a geographically distributed audience. The audience consists of other physicians collaborating on patients' health care management and physicians participating in continuing medical education. These physicians are at several locations with networks of different bandwidth and capabilities connecting them. Audiences also receive the patient case information on different computers ranging form high-end display workstations to laptops with low-resolution displays. WebPresent is a scalable networked multimedia tool which supports the presentation of hypertext, images, audio, video, and a white-board to remote physicians with hospital Intranet access. WebPresent allows the audience to receive customized information. The data received can differ in resolution and bandwidth, depending on the availability of resources such as display resolution and network bandwidth.

Genetic toxicology: web resources.  

PubMed

Genetic toxicology is the scientific discipline dealing with the effects of chemical, physical and biological agents on the heredity of living organisms. The Internet offers a wide range of online digital resources for the field of Genetic Toxicology. The history of genetic toxicology and electronic data collections are reviewed. Web-based resources at US National Library of Medicine (NLM), including MEDLINE, PUBMED, Gateway, Entrez, and TOXNET, are discussed. Search strategies and Medical Subject Headings (MeSH) are reviewed in the context of genetic toxicology. The TOXNET group of databases are discussed with emphasis on those databases with genetic toxicology content including GENE-TOX, TOXLINE, Hazardous Substances Data Bank, Integrated Risk Information System, and Chemical Carcinogenesis Research Information System. Location of chemical information including chemical structure and linkage to health and regulatory information using CHEMIDPLUS at NLM and other databases is reviewed. Various government agencies have active genetic toxicology research programs or use genetic toxicology data to assist fulfilling the agency's mission. Online resources at the US Food and Drug Administration (FDA), the US Environmental Protection Agency (EPA), the National Institutes of Environmental Health Sciences, and the National Toxicology Program (NTP) are outlined. Much of the genetic toxicology for pharmaceuticals, industrial chemicals and pesticides that is performed in the world is regulatory-driven. Regulatory web resources are presented for the laws mandating testing, guidelines on study design, Good Laboratory Practice (GLP) regulations, and requirements for electronic data collection and reporting. The Internet provides a range of other supporting resources to the field of genetic toxicology. The web links for key professional societies and journals in genetic toxicology are listed. Distance education, educational media resources, and job placement services are also available online in the field of genetic toxicology. As molecular biology and computational tools improve, new areas within genetic toxicology such as structural activity relationship analysis, mutational spectra databases and toxicogenomics, now have resources online as well.

Web-based access to an online atlas of anatomy: the Digital Anatomist Common Gateway Interface.

A World Wide Web Common Gateway Interface package is described for accessing existing online interactive atlases of anatomy. The Web interface accesses the same 2-D and 3-D images of human neuroanatomy, knee anatomy and thoracic viscera that are currently accessed by a custom interactive atlas in distance learning courses. Although the Web interface is too slow to replace the existing atlas, it provides a parallel access path that has much broader potential for development of a distributed distance learning network in anatomy. By maintaining both access methods to the same information sources we continue to satisfy the fast interactivity needs for our local courses, while at the same time providing a migration path to the Web as the capabilities of Web browsers evolve.

Multimedia Elements in a Hybrid Multi-Agent System for the Analysis of Web Usability  

NASA Astrophysics Data System (ADS)

The widespread use of the World Wide Web by persons from different age groups, diverse cultures, and with different computer skills has put more emphasis in the process of ensuring that web sites and applications are usable. On the other hand we can see how plain text web pages have been replaced by ones in which multimedia information (images, video and audio) are an important part of them. In this context we have developed a multi-agent system for analysing web usability that performs both static and dynamic analysis of web sites. The static analysis can examine certain multimedia issues related to usability (mostly associated with images) and in this paper we also comment on the issues related with video and audio technologies.

Web map is the hybrid of map and the World Wide Web (known as Web). It is usually created with WebGIS techniques. With the rapid social development, web maps oriented the public are facing pressure that dissatisfy the increased demanding. The geocoding database plays a key role in supporting query services effectively. The traditional geocoding method is laborious and time-consuming. And there is much online spatial information, which would be the supplementary information source for geocoding. Therefore, this paper discusses how to improve query services by web mining. The improvement can be described from three facets: first, improving location query by discovering and extracting address information from the Web to extend geocoding database. Second, enhancing the ability of optimum path query of public traffic and buffer query by spatial analyzing and reasoning on the extended geocoding database. Third, adjusting strategies of collecting data according to patterns discovered by web map query mining. Finally, this paper presents the designing of the application system and experimental results.

Web Map Services for Hurricane Data  

NASA Astrophysics Data System (ADS)

We have established several Web Map Services (WMS) that provide visualizations of numerical weather model data and satellite observations in support of NASA's Modeling, Analysis and Prediction Program 2005 Intensive Analysis (MAP05) Hurricane Project. The primary data component offered is the voluminous output (30GB/day) from the fourth-generation Goddard Earth Observing System (GEOS4) incorporating the finite-volume General Circulation Model (fvGCM). In addition, cloud imagery from the NASA MODIS and NOAA GOES sensors, and other ancillary datasets, are provided. We will discuss and demonstrate these servers using a simple web-based client. WMS is a web service interoperability specification developed by the Open Geospatial Consortium (OGC) and also approved for release as an International Standard (ISO 19128). WMS allows the user to request customized images of geospatial information, selecting exactly the dataset(s), times, geographic area and output size desired. A WMS client can combine output from multiple WMS servers, thus producing a unified view of information stored in a distributed network. Adoption of web services for access to hurricane data can be more efficient than older methods of data access. Specifically, instead of downloading huge datasets to a local workstation for analysis, the data can be stored on a remote server that generates visualizations of user-selected subsets of the data. In addition, a "clip-and-ship" capability can allow the user to visually inspect the data via WMS and then request numeric data values for only the subset of interest.

Surface Characterization of a Paper Web at the Wet End  

SciTech Connect

We present an algorithm for the detection and representation of structures and non-uniformities on the surface of a paper web at the wet end (slurry). This image processing/analysis algorithm is developed as part of a complete on-line web characterization system. Images of the slurry, carried by a fast moving table, are obtained using a stroboscopic light and a CCD camera. The images have very poor contrast and contain noise from a variety of sources. Those sources include the acquisition system itself, the lighting, the vibrations of the moving table being imaged, and the scattering water from the same table's movement. After many steps of enhancement, conventional edge detection methods were still inconclusive and were discarded. The facet model algorithm, is applied to the images and is found successful in detecting the various topographic characteristics of the surface of the slurry. Pertinent topographic elements are retained and a filtered image is computed based on the general appearance and characteristics of the structures in question. Morphological operators are applied to detect and segment regions of interest. Those regions are then filtered according to their size, elongation, and orientation.Their bounding rectangles are computed and superimposed on the original image. Real time implementation of this algorithm for on-line use is also addressed in this paper. The algorithm is tested on over 500 images of slurry and is found to detect nonuniformities on all 500 images. Locating and characterizing all different size structures is also achieved on all 500 images of the web.

Web Archiving Service  

NSDL National Science Digital Library

The California Digital Library has developed a unique online service called the "web archiving service" which allows librarians and scholars to have access to web content from critical sites that have been captured and preserved over the past few years. The publicly archived documents can be browsed or searched courtesy of a helpful search engine. The archives currently available include those that deal with the 2007 Southern California wildfires, the 2010 Winter Olympics, and the world of International Development Organizations. Visitors can also build their own archives of websites and documents. The "Information for" box on the far right hand side of the homepage gives a link for "WAS Curators", which provides a multitude of documents and videos for new curators to aid them in building their archive. Moving along, users will find that some of the documents include "Collection Planning", "Rights Management", and "WAS Administration Features". The videos explain some of the curator features available, such as how to "Display and Analyze Capture Results" and "Evaluating Sites for Capture".

AGRICOLA Web Gateway  

NSDL National Science Digital Library

The US National Agricultural Library, the largest agricultural library in the world, has a Web gateway to its mammoth AGRICOLA (AGRICultural OnLine Access) database. AGRICOLA "is a machine-readable database of bibliographic records created by the National Agricultural Library and its cooperators. Production of these records in electronic form began in 1970, but the database covers materials dating from the 16th century to the present. The records describe publications and resources encompassing all aspects of agriculture and allied disciplines, including plant and animal sciences, forestry, entomology, soil and water resources, agricultural economics, agricultural engineering, agricultural products, alternative farming practices, and food and nutrition." The Web interface is divided into two sections at this time, an online public access book catalog and a "journal article citation index." The book catalog contains bibliographic records produced since 1970, while the journal section contains records produced since 1985. Searching is available on six variables for each section, and several of the indexes are browseable, for ease of use.

Tele diagnostic by web  

NASA Astrophysics Data System (ADS)

Because of the development of multimedia technologies like Web and Internet, it now becomes possible to think about Tele Medicine and Tele Diagnostic for a distant place where no doctors and no nurses are situated at or are available. And also some kind of intelligence can be added onto them, which makes possible to give certain kind of medical treatment assistance or suggestions for a patient from a computer diagnostic base through the Internetworking. For doing this, here considers about a basic system of "Tele Diagnostic for a remote place" where it dose not have a doctor and a medical assistance. In order to implement the system, JAVA, VRML, HTML, and CORTONA are used as a basic language and a viewer. And also in order to add a kind of intelligence, Augmented Knowledge In Agent (AKIA) by using Back Propagation Neural Networks (BPNN) is used. And by this study, here can introduce the system that has the following basic mechanisms; By inputting physical data like temperature or blood pressure, the system would show a diagnostic assistance by TEXT. And also the bad place of body would be shown graphically if there were any. The system can be put onto Web, so that anybody could have this assistance at any place ubiquitously only if a person has Internetworking access.

The EMBRACE web service collection

The EMBRACE (European Model for Bioinformatics Research and Community Education) web service collection is the culmination of a 5-year project that set out to investigate issues involved in developing and deploying web services for use in the life sciences. The project concluded that in order for web services to achieve widespread adoption, standards must be defined for the choice of web service technology, for semantically annotating both service function and the data exchanged, and a mechanism for discovering services must be provided. Building on this, the project developed: EDAM, an ontology for describing life science web services; BioXSD, a schema for exchanging data between services; and a centralized registry (http://www.embraceregistry.net) that collects together around 1000 services developed by the consortium partners. This article presents the current status of the collection and its associated recommendations and standards definitions.

NASA Astrophysics Data System (ADS)

Amira (www.amiravis.com) is a powerful 3-D visualization package and has been employed recently by the science and engineering communities to gain insight into their data. We present a new web-based interface to Amira, packaged in a Java applet. We have developed a module called WEB-IS/Amira (WEB-IS2), which provides web-based access to Amira. This tool allows earth scientists to manipulate Amira controls remotely and to analyze, render and view large datasets over the internet, without regard for time or location. This could have important ramifications for GRID computing. The design of our implementation will soon allow multiple users to visually collaborate by manipulating a single dataset through a variety of client devices. These clients will only require a browser capable of displaying Java applets. As the deluge of data continues, innovative solutions that maximize ease of use without sacrificing efficiency or flexibility will continue to gain in importance, particularly in the Earth sciences. Major initiatives, such as Earthscope (http://www.earthscope.org), which will generate at least a terabyte of data daily, stand to profit enormously by a system such as WEB-IS/Amira (WEB-IS2). We discuss our use of SOAP (Livingston, D., Advanced SOAP for Web development, Prentice Hall, 2002), a novel 2-way communication protocol, as a means of providing remote commands, and efficient point-to-point transfer of binary image data. We will present our initial experiences with the use of Naradabrokering (www.naradabrokering.org) as a means to decouple clients and servers. Information is submitted to the system as a published item, while it is retrieved through a subscription mechanisms, via what is known as "topics". These topic headers, their contents, and the list of subscribers are automatically tracked by Naradabrokering. This novel approach promises a high degree of fault tolerance, flexibility with respect to client diversity, and language independence for the services (Erlebacher, G., Yuen, D.A., and F. Dubuffet, Current trends and demands in visualization in the geosciences, Electron. Geosciences, 4, 2001).

Arctic Circle Web  

NSDL National Science Digital Library

The Arctic Circle Web site at the University of Connecticut aims to stimulate among viewers a greater interest in the peoples and environment of the Arctic and Sub Arctic region. As stated on the Welcome page, this 'electronic circle' has three interrelated themes: natural resources; history and culture; social equity and environmental justice. In addressing these issues, the presentations utilize a range of textual and photographic materials, and in the near future, sound and short video recordings. Specific topics include discussions of Sustainability, Equity, and Environmental Protection; Northern Development and the Global Economy; Ethnographic Portraits of indigenous peoples in Alaska, Canada, Northwest Siberia, etc.; and specific studies dealing with the impact of petroleum, gas, hydroelectric, and other forms of large scale natural resource development in selected regions of the Circumpolar North. New material is being added on a regular basis.
