Block scheduling: Instructional practices in high school science classrooms  

NASA Astrophysics Data System (ADS)

Proponents of block scheduling perceive this approach to be a 'structural lever' to invite and impel teachers to change their teaching (Marshak, 1997). This desired shift is supposed to be manifest in movement from the traditional classroom structure, focusing on the teacher as lecturer or transmitter of subject matter, to that of teacher as coach with students as active learners, engaged in a variety of activities involving them individually and collaboratively in their education (Canady & Rettig, 1995). Block scheduling changes the formal structure of the school day, but does it really change pedagogical practices in high school science classrooms? Fraser's Individualized Classroom Environment Questionnaire (ICEQ) the instrument used in this study of science classes in five block-scheduled high schools in Connecticut, incorporates the tenets for an enriched classroom environment in its five scales or constructs: Participation---Extent to which students are encouraged to participate rather than be passive learners; Personalization---Emphasis on opportunities for individual students to interact with the teacher and on concern for the personal welfare and social growth of the individual; Investigation---Emphasis on the skills and processes of inquiry and their use in problem solving and investigation. Independence---Extent to which students are allowed to make decisions and have control over their own learning environment and behavior; Differentiation---Emphasis on the selective treatment of students on the basis of ability, learning style, interests, and rate of working (Fraser, 1990). The results and conclusions from this research study suggested that the block-scheduled high school science classes that participated in this research do promote, to varying degrees, those tenets that define an enriched classroom environment. Both the teachers and their classes of students perceived opportunities for Participation, Personalization, and Investigation constructs as prevalent in science instruction. However, Independence and Differentiation, although existent to some extent, were perceived to occur less by both the teachers and the students in their classes. The provision of more class time alone was not enough to drive the tenets of these two constructs significantly.

Heuristics for scheduling Earth observing satellites  

NASA Astrophysics Data System (ADS)

This paper describes several methods for assigning tasks to Earth Observing Systems Satellites (EOS). We present empirical results for three heuristics, called: Priority Dispatch (PD), Look Ahead (LA), and Genetic Algorithm (GA). These heuristics progress from simple to complex, from less accurate to more accurate, and from fast to slow. We present empirical results as applied to the Window-Constrained Packing problem (WCP). The WCP is a simplified version of the EOS scheduling problem. We discuss the problem of having more than one optimization criteria. We will also discuss the relationship between the WCP and the more traditional Knapsack and Weighted Early/Tardy problems.

Investigations into Generalization of Constraint-Based Scheduling Theories with Applications to Space Telescope Observation Scheduling  

NASA Astrophysics Data System (ADS)

This final report summarizes research performed under NASA contract NCC 2-531 toward generalization of constraint-based scheduling theories and techniques for application to space telescope observation scheduling problems. Our work into theories and techniques for solution of this class of problems has led to the development of the Heuristic Scheduling Testbed System (HSTS), a software system for integrated planning and scheduling. Within HSTS, planning and scheduling are treated as two complementary aspects of the more general process of constructing a feasible set of behaviors of a target system. We have validated the HSTS approach by applying it to the generation of observation schedules for the Hubble Space Telescope. This report summarizes the HSTS framework and its application to the Hubble Space Telescope domain. First, the HSTS software architecture is described, indicating (1) how the structure and dynamics of a system is modeled in HSTS, (2) how schedules are represented at multiple levels of abstraction, and (3) the problem solving machinery that is provided. Next, the specific scheduler developed within this software architecture for detailed management of Hubble Space Telescope operations is presented. Finally, experimental performance results are given that confirm the utility and practicality of the approach.

Nonlinear observer output-feedback MPC treatment scheduling for HIV  

PubMed Central

Background Mathematical models of the immune response to the Human Immunodeficiency Virus demonstrate the potential for dynamic schedules of Highly Active Anti-Retroviral Therapy to enhance Cytotoxic Lymphocyte-mediated control of HIV infection. Methods In previous work we have developed a model predictive control (MPC) based method for determining optimal treatment interruption schedules for this purpose. In this paper, we introduce a nonlinear observer for the HIV-immune response system and an integrated output-feedback MPC approach for implementing the treatment interruption scheduling algorithm using the easily available viral load measurements. We use Monte-Carlo approaches to test robustness of the algorithm. Results The nonlinear observer shows robust state tracking while preserving state positivity both for continuous and discrete measurements. The integrated output-feedback MPC algorithm stabilizes the desired steady-state. Monte-Carlo testing shows significant robustness to modeling error, with 90% success rates in stabilizing the desired steady-state with 15% variance from nominal on all model parameters. Conclusions The possibility of enhancing immune responsiveness to HIV through dynamic scheduling of treatment is exciting. Output-feedback Model Predictive Control is uniquely well-suited to solutions of these types of problems. The unique constraints of state positivity and very slow sampling are addressable by using a special-purpose nonlinear state estimator, as described in this paper. This shows the possibility of using output-feedback MPC-based algorithms for this purpose.

Observatorio Astrofísico de Javalambre: observation scheduler and sequencer  

NASA Astrophysics Data System (ADS)

Observational strategy is a critical path in any large survey. The planning of a night requires the knowledge of the fields observed, the quality of the data already secured, and the ones still to be observed to optimize scientific returns. Finally, field maximum altitude, sky distance/brightness during the night and meteorological data (cloud coverage and seeing) have to be taken into account in order to increase the chance to have a successful observation. To support the execution of the J-PAS project at the Javalambre Astrophysical Observatory, we have prepared a scheduler and a sequencer (SCH/SQ) which takes into account all the relevant mentioned parameters. The scheduler first selects the fields which can be observed during the night and orders them on the basis of their figure of merit. It takes into account the quality and spectral coverage of the existing observations as well as the possibility to get a good observation during the night. The sequencer takes into account the meteorological variables in order to prepare the observation queue for the night. During the commissioning of the telescopes at OAJ, we expect to improve our figures of merit and eventually get to a system which can function semi-automatically. This poster describes the design of this software.

Observing with HST V: Planning and Scheduling HST Instrument Calibrations  

NASA Astrophysics Data System (ADS)

HST has an extensive program of science instrument calibrations that consumes up to 10% of all available HST observing time. Its major goals are to provide calibration data for the HST science program and to monitor instrument health and the stability of instrument performance. The program also includes a variety of instrument and spacecraft tests, flight software installations, and other activities which ensure the vitality of HST. A prerequisite for achieving these goals is the effective planning and scheduling of HST calibration observations. The purpose of this process is to ensure the timely development of calibration proposals; to ensure accurate planning and timely execution of calibration proposals; to provide the instrument teams and engineering staff with a clear view of when instrument calibrations are supposed to execute; and to give HST observers insight into the plans for calibration that could affect their data reduction and analysis strategies. This paper describes the nature and process of HST calibration planning and scheduling, along with the specific calibration plans for Cycle 4.

Observing with HST V: Improvements to the Scheduling of HST Parallel Observations  

NASA Astrophysics Data System (ADS)

Recent improvements to the Hubble Space Telescope (HST) ground system have significantly increased the frequency of pure parallel observations, i.e. the simultaneous use of multiple HST instruments by different observers. Opportunities for parallel observations are limited by a variety of timing, hardware, and scientific constraints. Formerly, such opportunities were heuristically predicted prior to the construction of the primary schedule (or calendar), and lack of complete information resulted in high rates of scheduling failures and missed opportunities. In the current process the search for parallel opportunities is delayed until the primary schedule is complete, at which point new software tools are employed to identify places where parallel observations are supported. The result has been a considerable increase in parallel throughput. A new technique, known as ``parallel crafting,'' is currently under development to streamline further the parallel scheduling process. This radically new method will replace the standard exposure logsheet with a set of abstract rules from which observation parameters will be constructed ``on the fly'' to best match the constraints of the parallel opportunity. Currently, parallel observers must specify a huge (and highly redundant) set of exposure types in order to cover all possible types of parallel opportunities. Crafting rules permit the observer to express timing, filter, and splitting preferences in a far more succinct manner. The issue of coordinated parallel observations (same PI using different instruments simultaneously), long a troublesome aspect of the ground system, is also being addressed. For Cycle 5, the Phase II Proposal Instructions now have an exposure-level PAR WITH special requirement. While only the primary's alignment will be scheduled on the calendar, new commanding will provide for parallel exposures with both instruments.

Refining MARGINS Mini-Lessons Using Classroom Observations  

NASA Astrophysics Data System (ADS)

One of the challenges that we face in developing teaching materials or activities from research findings is testing the materials to determine that they work as intended. Traditionally faculty develop material for their own class, notice what worked and didn’t, and improve them the next year. However, as we move to a community process of creating and sharing teaching materials, a community-based process for testing materials is appropriate. The MARGINS project has piloted such a process for testing teaching materials and activities developed as part of its mini-lesson project (http://serc.carleton.edu/margins/index.html). Building on prior work developing mechanisms for community review of teaching resources (e.g. Kastens, 2002; Hancock and Manduca, 2005; Mayhew and Hall, 2007), the MARGINS evaluation team developed a structured classroom observation protocol. The goals of field testing are to a) gather structured, consistent feedback for the lesson authors based on classroom use; b) guide reviewers of these lessons to reflect on research-based educational practice as a framework for their comments; c) collect information on the data and observations that the reviewer used to underpin their review; d) determine which mini-lessons are ready to be made widely available on the website. The protocol guides faculty observations on why they used the activity, the effectiveness of the activity in their classroom, the success of the activity in leading to the desired learning, and what other faculty need to successfully use the activity. Available online (http://serc.carleton.edu/margins/protocol.html), the protocol can be downloaded and completed during instruction with the activity. In order to encourage review of mini-lessons using the protocol, a workshop focused on review and revision of activities was held in May 2009. In preparation for the workshop, 13 of the 28 participants chose to field test a mini-lesson prior to the workshop and reported that they found this process instructive. Activity authors found the observations very helpful and the first mini-lessons have now been revised using feedback from testers. Initial results show that the tested mini-lessons give students hands-on experience with scientific data and help students make connections between geologic phenomena and data. Productive feedback ranged from suggestions for improving activity design, adaptations for other audiences, suggestions for clearer presentation, and tips for using the materials. The team plans to broaden the use of the protocol to test and refine all of the mini-lessons in the MARGINS collection.

Student–teacher interactions are dynamic relationships that change and evolve over the course of a school year. Measuring classroom quality through observations that focus on these interactions presents challenges when observations are conducted throughout the school year. Variability in observed scores could reflect true changes in the quality of student–teacher interaction or simply reflect measurement error. Classroom observation protocols should be

A dynamic scheduling method of Earth-observing satellites by employing rolling horizon strategy.  

PubMed

Focused on the dynamic scheduling problem for earth-observing satellites (EOS), an integer programming model is constructed after analyzing the main constraints. The rolling horizon (RH) strategy is proposed according to the independent arriving time and deadline of the imaging tasks. This strategy is designed with a mixed triggering mode composed of periodical triggering and event triggering, and the scheduling horizon is decomposed into a series of static scheduling intervals. By optimizing the scheduling schemes in each interval, the dynamic scheduling of EOS is realized. We also propose three dynamic scheduling algorithms by the combination of the RH strategy and various heuristic algorithms. Finally, the scheduling results of different algorithms are compared and the presented methods in this paper are demonstrated to be efficient by extensive experiments. PMID:23690742

NASA Astrophysics Data System (ADS)

From paper proposals and photographic plate observations of the early days to today's submission, CFHT (Canada-France-Hawaii Telescope) went through many changes. However, a few basic features of the observatory did not change over the years, reflecting the very nature of an international collaboration deeply rooted in the concept of equal role and responsibilities of its two main partners, Canada and France. Nevertheless, the overall role of the observatory strongly evolved over the past years, as demonstrated by a more business-like management emphasizing the services rendered by the observatory to its customers, a move made possible by the Queues Service Observing mode. Together with a careful selection of its new generation of instruments, it allows the observatory to play a significant role in astronomy in spite of the relatively small size of its telescope.

Teacher cognitive functioning as a factor in observed variety and level of classroom teaching behavior  

NASA Astrophysics Data System (ADS)

A review of the literature suggests a relationship between life-long development of formal reasoning schema and performance in professional education careers. The study investigated implications of cognitive development of preservice teachers as it relates to their classroom teaching performance. Ninety-one seniors involved in a field-oriented teacher education program were given classroom responsibilities which included teaching a science unit. Formal thinking abilities were assessed using two types of developmental level tasks, performance on traditional type Piagetian tasks and recognition of formal thought approaches in solving educational tasks. Professional behaviors were assessed using observational ratings of classroom instructional and planning activities. Subjects assessed as formal operational, 30% of sample, using Piagetian performance tasks, had significantly higher facility in performing model classroom teaching behaviors than transitional or concrete subjects. Higher recognition ability of formal thought approaches to teaching was not related to facility in performing classroom teaching when compared to performance on Piagetian tasks. The relationship held up in seven of eight broad teaching behavior categories observed in classroom instruction. The results supported a general portrait of teaching behavior specifically related to teachers of differing cognitive functional levels. Implications for professional training programs are discussed.

Feedback schedules for motor-skill learning: the similarities and differences between physical and observational practice.  

PubMed

In 2 experiments, the authors assessed different knowledge of results (KR) schedules for observational and physical practice. In Experiment 1, participants had to learn a sequence timing task under either a bandwidth (KR being delivered when participants’ performance was outside a predefined bandwidth or range) or yoked (same number of KRs provided as the bandwidth group) KR procedure. The results show that for both practice conditions the bandwidth KR schedule was more effective in promoting learning than the yoked schedule. During Experiment 2, a KR frequency was controlled (100% or 33% KR) and the data indicate that a reduced KR frequency only enhanced the learning of observers. Because a low KR frequency improves the sensory process controlling motor learning, the authors propose that action observation may be perceptual in nature. PMID:20862778

On the representativeness of behavior observation samples in classrooms.  

PubMed

School consultants who rely on direct observation typically conduct observational samples (e.g., 1 30-min observation per day) with the hopes that the sample is representative of performance during the remainder of the day, but the representativeness of these samples is unclear. In the current study, we recorded the problem behavior of 3 referred students for 4 consecutive school days between 9:30 a.m. and 2:30 p.m. using duration recording in consecutive 10-min sessions. We then culled 10-min, 20-min, 30-min, and 60-min observations from the complete record and compared these observations to the true daily mean to assess their accuracy (i.e., how well individual observations represented the daily occurrence of target behaviors). The results indicated that when behavior occurred with low variability, the majority of brief observations were representative of the overall levels; however, when behavior occurred with greater variability, even 60-min observations did not accurately capture the true levels of behavior.

Objective To replicate the factor structure and predictive validity of revised Autism Diagnostic Observation Schedule algorithms in an independent dataset (N = 1,282). Method Algorithm revisions were replicated using data from children ages 18 months to 16 years collected at 11 North American sites participating in the Collaborative Programs for Excellence in Autism and the Studies to Advance Autism Research and Treatment. Results Sensitivities and specificities approximated or exceeded those of the old algorithms except for young children with phrase speech and a clinical diagnosis of pervasive developmental disorders not otherwise specified. Conclusions Revised algorithms increase comparability between modules and improve the predictive validity of the Autism Diagnostic Observation Schedule for autism cases compared to the original algorithms.

Diagnosing autism spectrum disorders in adults: the use of Autism Diagnostic Observation Schedule (ADOS) module 4.  

PubMed

Autism Diagnostic Observation Schedule (ADOS) module 4 was investigated in an independent sample of high-functioning adult males with an autism spectrum disorder (ASD) compared to three specific diagnostic groups: schizophrenia, psychopathy, and typical development. ADOS module 4 proves to be a reliable instrument with good predictive value. It can adequately discriminate ASD from psychopathy and typical development, but is less specific with respect to schizophrenia due to behavioral overlap between autistic and negative symptoms. However, these groups differ on some core items and explorative analyses indicate that a revision of the algorithm in line with Gotham et al. (J Autism Dev Disord 37: 613-627, 2007) could be beneficial for discriminating ASD from schizophrenia. PMID:21153873

[The BASYS observation system for the analysis of aggressive behavior in classroom-settings].  

PubMed

Educational or therapeutic measures of aggressive student behavior are often based on the judgments of teachers. However, empirical studies show that the objectivity of these judgments is generally low. In order to assess aggressive behavior in classroom settings, we developed a context-sensitive observational system. The observation system exists in a version for teachers in action as well as a version for the uninvolved observer. The teacher version allows categorizing aggressive behavior while teaching. The aim is to differentiate the perception and the judgments of teachers, so that the judgments can serve as trustable diagnostic information. The version for an independent observer, in addition, contains categories to collect information about the context in which aggressions take place. The behavior observation system was tested in four field-studies in regular and special classes. The empirical results show that, after training, teachers were able to make objective observations, and that aggressive behavior depends to a large extent on situational factors. The system allows identification of problematic people-environment relationships and the derivation of intervention measures. PMID:22748725

[Polish version of the ADOS (autism diagnostic observation schedule-generic)].  

PubMed

The article presents the Polish version of the autism diagnostic observation schedule-generic (ADOS), which together with the autism diagnostic interview-revised (ADI-R) is cited as the "gold standard" for the diagnosis of autism. The ADOS is a standardised, semistructured observation protocol appropriate for children and adults of differing age and language levels. It is linked to ICD-10 and DSM-IV-TR criteria. The ADOS consists of four modules, ranging from module 1 for nonverbal individuals to module 4 for verbally fluent adults. The adequate inter-rater reliability for items has been established. The protocol has high discriminant validity and distinguishes children with pervasive developmental disorders from children, who are outside of the spectrum. Although it does not enable to distinguish individuals with pervasive developmental disorder, unspecified from individuals with childhood autism. The paper presents subsequent steps of the translation process of the original version into Polish, as well as a chosen adaptation strategy of the Polish version. The ADOS is a very useful tool both for clinical diagnosis and for the scientific purpose diagnosis. In this last case it is extremely important to use a standardised method. Until now, there was no standardised diagnostic tool for autism in Poland. PMID:23394018

Use of the Autism Diagnostic Observation Schedule (ADOS) in a clinical setting.  

PubMed

The aim of this study was to examine the Autism Diagnostic Observation Schedule (ADOS) as it is commonly used in clinical practice. ADOS classifications were compared to final diagnoses given by a multidisciplinary team to 584 children referred for evaluation for possible autism spectrum disorder (ASD) at the Cincinnati Children's Hospital Medical Center. A total of 177 children were evaluated with a Module 1 (87 No Words), 198 with a Module 2 (90 < 5 years) and 209 with a Module 3. Of these, 142 (26%) were diagnosed with autism, 185 (32%) with non-autism ASD, and 257 (44%) with non-spectrum disorders. Sensitivities were moderate to high on both original and revised algorithms, while specificities were substantially lower than those previously reported. This difference is likely attributable to the composition of the sample that included many children with a broad array of developmental and behavioral disorders. The clinical impression of the team member who administered the ADOS was critical to the accuracy of the overall diagnosis. Using numeric scores alone resulted in misclassification from false positive results. The study highlights the importance of the qualitative interactions of the ADOS activities as well as the score in diagnostic decision making. PMID:21339248

Direct observation was utilized to study how 5 children with mild-to-moderate deafness participated within inclusive classroom settings. Responses to practice and prompt opportunities, levels of prompting required to follow classroom directions, and engagement were analyzed across students with mild-to-moderate deafness and were compared to students with normal hearing. Similar responses to practice and prompt opportunities were observed across students, and engagement data indicated that 4 children with mild-to-moderate deafness had similar rates to their peers. However, children with mild-to-moderate deafness required higher levels of prompting and were less accurate at following classwide verbal prompts. Agreement data on variables ranged between 83% and 99%, with the exception of 2 prompting levels. Social validity judgments indicated that the information was useful and important. Potential uses for data include consultation with teachers regarding interventions to increase student engagement and research regarding inclusionary practices. PMID:20591839

Variable sleep schedules and outcomes in children with psychopathological problems: preliminary observations  

PubMed Central

Background Night-to-night variability in sleep of children with attention deficit hyperactivity disorder (ADHD) may be a mediator of behavioral phenotype. We examined the potential association between alertness, sleep, and eating behaviors in children with ADHD and comorbid problems. Methods Sleep was monitored by actigraphy for 7 days. Questionnaires were used to assess sleep complaints, habits and food patterns by parental report, and sleep complaints and sleepiness by child report. Results The group comprised 18 children, including 15 boys, aged 9.4 ± 1.7 years, 88.9% Caucasian, who took one or multiple medications. Children slept on average for 6 hours and 58 minutes with a variability of 1 hour 3 minutes relative to the mean, and their sleepiness scores were highly variable from day to day. Most children had a normal body mass index (BMI). Sleepiness and BMI were associated with sleep schedules and food patterns, such that they accounted for 76% of variance, predominantly by the association of BMI with mean wake after sleep onset and by bedtime sleepiness, with wake after sleep onset variability. Similarly, 97% of variance was shared with eating behaviors, such as desserts and snacks, and fast food meals were associated with morning sleepiness. Conclusion Disrupted sleep and sleepiness appears to favor unhealthy food patterns and may place children with ADHD at increased risk for obesity.

Overlap between autism and specific language impairment: comparison of Autism Diagnostic Interview and Autism Diagnostic Observation Schedule scores.  

PubMed

Autism and specific language impairment (SLI) are developmental disorders that, although distinct by definition, have in common some features of both language and social behavior. The goal of this study was to further explore the extent to which specific clinical features of autism are seen in SLI. The children with the two disorders, matched for non-verbal IQ, were compared on the Autism Diagnostic Interview-Revised (ADI-R) and the Autism Diagnostic Observation Schedule (ADOS). In the SLI group, 41% met autism or autism spectrum cut-offs for social or communication domains either on the ADI or ADOS or both. No relationship was found between the language deficits exhibited by the children with SLI and their scores on the ADI and ADOS. These findings contribute to evidence that there is some overlap in social and communicative deficits between autism and SLI, supporting the view that autism and SLI share etiologic factors. This continuum of pathology between SLI and autism appears to range from structural language abnormalities as seen in individuals with SLI to individuals with SLI with both structural and social abnormalities to individuals with autism with pragmatic impairment and language abnormalities.

Observations of adolescent peer resistance skills following a classroom-based healthy relationship program: a post-intervention comparison.  

PubMed

This study examines peer resistance skills following a 21-lesson classroom-based intervention to build healthy relationships and decrease abusive and health-risk behaviors among adolescents. The Fourth R instructs students in positive relationship skills, such as negotiation and delay, for navigating challenging peer and dating scenarios. Observational data from 196 grade 9 students participating in a larger cluster randomized controlled trial were used to evaluate post-intervention acquisition of peer resistance skills. Pairs of students engaged in a role play paradigm with older student actors, where they were subjected to increasing pressure to comply with peer requests related to drugs and alcohol, bullying, and sexual behavior. Specific and global measures of change in peer resistance responses were obtained from two independent sets of observers, blinded to condition. Specific peer resistance responses (negotiation, delay, yielding to pressure, refusal, and compliance) were coded by research assistants; global peer resistance responses were rated by teachers from other schools (thinking / inquiry, application, communication, and perceived efficacy). Students who received the intervention were more likely to demonstrate negotiation skills and less likely to yield to negative pressure relative to controls. Intervention students were also more likely to use delay than controls; control girls were more likely to use refusal responses; the number of times students complied with peer requests did not differ. Teacher ratings demonstrated significant main effects favoring intervention youth on all measures. Program and research implications are highlighted. PMID:22057307

Teaching strategies and student achievement in high school block scheduled biology classes  

NASA Astrophysics Data System (ADS)

The objectives of this study included determining whether teachers in block or traditionally scheduled biology classes (1) implement inquiry-based instruction more often or with different methods, (2) understand the concept of inquiry-based instruction as it is described in the National Science Standards, (3) have classes with significantly different student achievement, and (4) believe that their school schedule facilitates their use of inquiry-based instruction in the classroom. Biology teachers in block and non-block scheduled classes were interviewed, surveyed, and observed to determine the degree to which they implement inquiry-based instructional practices in their classrooms. State biology exams were used to indicate student achievement. Teachers in block scheduled and traditional classes used inquiry-based instruction with nearly the same frequency. Approximately 30% of all teachers do not understand the concept of inquiry-based instruction as described by the National Science Standards. No significant achievement differences between block and traditionally scheduled biology classes were found using ANCOVA analyses and a nonequivalent control-group quasi-experimental design. Using the same analysis techniques, significant achievement differences were found between biology classes with teachers who used inquiry-based instruction frequently and infrequently. Teachers in block schedules believed that their schedules facilitated inquiry-based instruction more than teachers in traditional schedules.

Automated Telescope Scheduling  

NASA Astrophysics Data System (ADS)

The Giant Metrewave Radio Telescope, commonly known as GMRT, is the world's largest low frequency radio telescope. Being a rare resource, efficient planning of GMRT is needed. Planning consists of scheduling a pre-selected large collection of scientific proposals up to half a year in advance. Scheduling becomes complex due to the variety of astronomical, equipment and logistical constraints. The goal is to schedule each observation to appropriate time slots so that constraints violation is minimized. We have developed a scheduler software named GSCHED to assist in scheduling and to increase the utilization of GMRT.

Maintenance scheduling

The requirements for daily, weekly, monthly and overtime maintenance scheduling of coal-fired power plants are discussed. It is concluded that maintenance scheduling is as essential as the physical performance of the work itself. By prescheduling maintenance, the optimum utilization of manpower and equipment reliability will be obtained. Spare parts, special tools and service engineer requirements can be anticipated with reasonable scheduling. Meetings are a distasteful word in anyone's vocabulary. However, close communication, between operation and maintenance, is a must to insure that both departments are aware of the job status and progress. Improved communication and scheduling of equipment maintenance can help break down the barrier that has developed between the two Departments.

NASA Astrophysics Data System (ADS)

The Robert C.

Using observing criteria; observer availability and qualifications for remote observing; three-dimensional weather forecasts; and telescope state, the DSS software optimally schedules observers 24 to 48 hours in advance for a telescope that has a wide-range of capabilities and a geographical location with variable weather patterns. The DSS project was closed October 28, 2011 and will now enter a continuing maintenance and enhancement phase. Recent improvements include a new resource calendar for incorporating telescope maintenance activities, a sensitivity calculator that leverages the scheduling algorithms to facilitate consistent tools for proposal preparation, improved support for monitoring observations, scheduling of high frequency continuum and spectral line observations for both sparse and fully sampled array receivers, and additional session parameters for observations having special requirements.

Robust telescope scheduling  

NASA Astrophysics Data System (ADS)

This paper presents a technique for building robust telescope schedules that tend not to break. The technique is called Just-In-Case (JIC) scheduling and it implements the common sense idea of being prepared for likely errors, just in case they should occur. The JIC algorithm analyzes a given schedule, determines where it is likely to break, reinvokes a scheduler to generate a contingent schedule for each highly probable break case, and produces a 'multiply contingent' schedule. The technique was developed for an automatic telescope scheduling problem, and the paper presents empirical results showing that Just-In-Case scheduling performs extremely well for this problem.

Evaluating LSST Schedule Realizations  

NASA Astrophysics Data System (ADS)

How would one quantify and graphically represent the scientific performance of various scientific goals of a survey strategy? A simulated 10-year LSST observing schedule will produce 2.5x106 visits and in order to evaluate a simulated schedule, the project, collaborating scientists and team have defined tools called Merit Functions. Each Merit Function evaluates the success of a simulation in acquiring images with properties which characterize a specific parameter. Each Merit Function can be applied to a set of simulations, providing a single numerical value (a Metric) representative of the function and the simulation. The complete set of metric values can be used to quantitatively compare the performance of multiple simulated schedules. At present we are working with 6 groups of Merit functions: Airmass, Astrometry, Early Good Images, Randomization, Solar System, Variables & Transients and Uniformity. The Metrics derived from the Merit functions offer the possibility of comparing simulations quantitatively, within the context of defined functions. However, with dozens of metrics, it is still a challenge to present the results in a format that is both informative and objective. In this poster we show an early attempt to summarize the comparison of metric sets graphically.

Dedicated heterogeneous node scheduling including backfill scheduling  

SciTech Connect

A method and system for job backfill scheduling dedicated heterogeneous nodes in a multi-node computing environment. Heterogeneous nodes are grouped into homogeneous node sub-pools. For each sub-pool, a free node schedule (FNS) is created so that the number of to chart the free nodes over time. For each prioritized job, using the FNS of sub-pools having nodes useable by a particular job, to determine the earliest time range (ETR) capable of running the job. Once determined for a particular job, scheduling the job to run in that ETR. If the ETR determined for a lower priority job (LPJ) has a start time earlier than a higher priority job (HPJ), then the LPJ is scheduled in that ETR if it would not disturb the anticipated start times of any HPJ previously scheduled for a future time. Thus, efficient utilization and throughput of such computing environments may be increased by utilizing resources otherwise remaining idle.

A Descriptive Assessment of Instruction-Based Interactions in the Preschool Classroom  

PubMed Central

The current study describes preschool teacher–child interactions during several commonly scheduled classroom activities in which teachers deliver instructions. An observation system was developed that incorporated measurement of evidence-based compliance strategies and included the types of instructions delivered (e.g., integral or deficient directives, embedded directives, “do” or “don't” commands), the children's behavior with respect to the instructions (e.g., compliance, noncompliance, active avoidance, problem behavior), and the differential responses of the teacher to the child's behavior following an instruction (e.g., appropriate or inappropriate provision of attention and escape). After 4 classroom teachers were observed at least five times in each of five target activities, simple and conditional probabilities were calculated. Results indicated that (a) the frequency of instruction and probability of compliance varied as a function of activity type, (b) “do” commands and directive prompts were delivered almost to the exclusion of “don't” commands and nondirective prompts, (c) the likelihood of compliance was highest following an embedded or an integral directive prompt, and (d) although putative social reinforcers were more likely to follow noncompliance than compliance and were highly likely following problem behavior, compliance occurred over twice as much as noncompliance, and problem behavior during instructions was very low. Implications for using descriptive assessments for understanding and improving teacher–child interactions in the preschool classroom are discussed.

Comparative pharmacokinetics of plasma- and albumin-free recombinant factor VIII in children and adults: the influence of blood sampling schedule on observed age-related differences and implications for dose tailoring  

PubMed Central

Summary Background: Dose tailoring of coagulation factors requires reliably estimated and reproducible pharmacokinetics (PK) in the individual patient. Objectives: To investigate the contribution of both biological and methodological factors to the observed variability of factor VIII (FVIII) PK, with the focus on differences between children and adults, and to examine the implications for dosing. Patients: Data from 52 1–6-year-old and 100 10–65-year-old patients with hemophilia A (FVIII ? 2 IU dL?1) in three clinical studies were included. Results: In vivo recovery was lower, weight-adjusted clearance was higher and FVIII half-life was on average shorter in children than in adults. However, a reduced blood sampling schedule for children was estimated to account for up to one half of the total observed differences. Intrapatient variance in PK was smaller than interpatient variance in 10–65-year-olds. Age and ratio of actual to ideal weight only showed weak relationships with PK parameters. Variance in PK caused large variance in the calculated dose required to maintain a target FVIII trough level during prophylactic treatment. Conclusion: Differences in blood sampling schedules should be taken into account when results from different PK studies are compared. However, even with this consideration, PK cannot be predicted from observable patient characteristics but must be determined for the individual. Because the influence of reducing the blood sampling was minor in comparison to the true variance between patients, a reduced blood sampling protocol can be used. Low intrapatient variability supports the use of PK measurements for dose tailoring of FVIII.

Model Predictive Sensor Scheduling  

NASA Astrophysics Data System (ADS)

The objective of sensor scheduling is to select a sensor (or a group of sensors) from multiple sensors at each time step so as to perform optimally a task based on the sensed data. In this paper, we pose a model predictive type sensor scheduling problem with a general class of criterion functions including the trace, the maximal eigenvalue, and the determinant of the error covariance, for discrete-time linear Gaussian time-varying systems, and develop an approach to solve this problem based on the dynamic programming. We show first that, in a special case of the model predictive deterministic sensor scheduling problem where the Riccati recursion of the error covariance satisfies a specific structural condition, the online optimization using the dynamic programming is reduced to a static optimization, and hence the scheduling algorithm can be easily implemented online. Next, we pose a model predictive stochastic sensor scheduling problem to relax the condition of the deterministic sensor scheduling problem, and show an alternative condition where the optimization is reduced so that the scheduling algorithm can be easily implemented online. Finally, we discuss an example to illustrate the two sensor scheduling algorithms.

Science teachers' understanding and use of instructional strategies within the 4 x 4 block schedule  

NASA Astrophysics Data System (ADS)

The primary purpose of this researcher was to investigate how science teachers engage students under the 4 x 4 block schedule and how the teachers' understanding of how they use instructional strategies influenced their lessons. As an inquiry-based approach has been adopted by the National Science Standards, research has suggested that block scheduling provides more time for teachers to incorporate varied strategies such as inquiry-based and cooperative learning teaching which have philosophical roots in a social constructivist philosophy. This research investigated the questions: What instructional strategies do science teachers use to engage students on the 4 x 4 block schedule? How do science teachers understand their use of instructional strategies? The methodology was qualitative in nature and involved a multiple case study of three high school science teachers at a large rural county high school. Data sources included pre-observation interviews, classroom observations, post-observation interviews, and the collection of documents and artifacts such as lesson plans, student hand-outs, worksheets, laboratory exercises, homework and other document(s) the teacher used to prepare for or implement a lesson. The evidence observed in this study, suggests that the strategies used by these three science teachers remain mostly didactic in nature. Although the teachers reported in the interview phase of this research that they use a wide variety of strategies, what was observed within the 4 x 4 block structure was the use of different didactic strategies, not different holistic strategies. Although the teachers were aware of more holistic strategies such as inquiry-based and cooperative learning, they were not adopted nor adapted within the lesson. The three teachers used strategies that were consistent with their scientific realist views concerning the nature of science. These scientific realist philosophies are antithetical to a social constructivist approach to teaching and learning, which is what the National Research Council suggests science teachers adopt.

Redefining classroom instruction.  

PubMed

In this study, the role of the classroom instructor was redefined from a "lecturer" responsible for delivering the core curriculum to a "facilitator" at the center of an active learning environment. Web-based lectures were used to provide foundation content to students outside of the classroom, which made it possible to improve the quality of student-faculty contact time in the classroom. Students reported that this hybrid format of instruction afforded them a better understanding of the content, a higher probability of retaining the content, and the opportunity to spend more time thinking about the application of the content compared with more traditional lecture-based methods of instruction.

Chandra mission scheduling on-orbit experience  

NASA Astrophysics Data System (ADS)

Scheduling observatory time to maximize both day-to-day science target integration time and the lifetime of the observatory is a formidable challenge. Furthermore, it is not a static problem. Of course, every schedule brings a new set of observations, but the boundaries of the problem change as well. As spacecraft ages, its capabilities may degrade. As in-flight experience grows, capabilities may expand. As observing programs are completed, the needs and expectations of the science community may evolve. Changes such as these impact the rules by which a mission scheduled. In eight years on orbit, the Chandra X-Ray Observatory Mission Planning process has adapted to meet the challenge of maximizing day-to-day and mission lifetime science return, despite a consistently evolving set of scheduling constraints. The success of the planning team has been achieved, not through the use of complex algorithms and optimization routines, but through processes and home grown tools that help individuals make smart short term and long term Mission Planning decisions. This paper walks through the processes and tools used to plan and produce mission schedules for the Chandra X-Ray Observatory. Nominal planning and scheduling, target of opportunity response, and recovery from on-board autonomous safing actions are all addressed. Evolution of tools and processes, best practices, and lessons learned are highlighted along the way.

Multiple punishment schedule1  

PubMed Central

Concurrent schedules of punishment and fixed-ratio reinforcement were studied in six white Carneaux pigeons. Two stimuli were alternated on the translucent key which served as the response mechanism. The pigeons were exposed to continuous punishment in one stimulus and first response punishment in the other. It was found that continuous punishment suppressed the fixed-ratio performance more than did punishment of the first response. Typically, a ratio run of responses was completed in spite of the onset of continuous punishment. Responding was then reduced for the remainder of the continuous punishment stimulus, except for those times when responding was initiated near the end of the stimulus. The results indicate that a multiple schedule can be used to compare different schedules of punishment in the same organism.

Becoming Galileo in the Classroom  

NASA Astrophysics Data System (ADS)

Galileo's contributions are so familiar as to be taken for granted, obscuring the exploratory process by which his discoveries arose. The wonder that Galileo experienced comes alive for undergraduates and teachers that I teach, when they find themselves taking Galileo's role by means of their own explorations. These classroom journeys include: sighting through picture frames to understand perspective, watching the night sky, experimenting with lenses and motion, and responding to Galileo's story. In teaching, I use critical exploration, the research pedagogy developed by Eleanor Duckworth that arose historically from both the clinical interviewing of Jean Piaget and B"arbel Inhelder and the Elementary Science Study of the 1960s. During critical explorations, the teacher supports students' investigations by posing provocative experiences while interactively following students' emergent understandings. In the context of Galileo, students learned to observe carefully, trust their observations, notice things they had never noticed before, and extend their understanding in the midst of pervasive confusion. Personal investment moved students to question assumptions that they had never critically evaluated. By becoming Galileo in today's classroom, we found the ordinary world no less intriguing and unsettling to explore, as the historical world of protagonists in Galileo's Dialogue.

Eyeglasses in the Classroom  

NASA Astrophysics Data System (ADS)

Optical phenomena can be divided into two categories: ray optics and wave optics. The former is also known as geometrical optics, and examples are reflection and refraction, while the latter is also known as physical optics and includes interference and diffraction. In most textbooks, these two topics are presented in separate chapters.1 To help students grasp corresponding principles, instructors often emphasize the contrast between these two categories. For example, the length scale of objects encountered by light beams is taken as an indicator to differentiate these two. When the scale is microscopic (down to the wavelength at 550 nm for green light), the light shall be treated as a wave, while at a macroscopic scale (start from a few mm for a tiny lens), the light shall be taken as a ray. Diffraction effects are almost always negligible in the formation of images by lens, and refraction effects can also be neglected safely in the discussions of interference. As a result, some students get the wrong impression that these two phenomena must manifest in quite different regimes. In this paper, we show that eyeglasses can be a very handy tool to demonstrate these two phenomena at the same time, working as a lens for light rays and also showing interference of light waves from reflections off the lens coating. According to a recent survey, more than 80% of college students in Taiwan are nearsighted, and eyeglasses are easily accessible in the classroom. Students are guided to observe, describe, and then provide qualitative explanations. And some of the students might take the challenge to work out quantitative calculations as exercises after class.

The companion “1999 Transportation ‘Barriers’ Analysis” analyzes the data and identifies existing and potential problems that may prevent or delay transportation activities based on the data presented. The “1999 Transportation Baseline Schedule” (this report) uses the same data to provide an overview of the transportation activities of DOE EM waste/materials. This report can be used to identify areas where stakeholder interface is needed, and to communicate to stakeholders the quantity/schedule of shipments going through their area. Potential bottlenecks in the transportation system can be identified; the number of packages needed, and the capacity needed at receiving facilities can be planned. This report offers a visualization of baseline DOE EM transportation activities for the 11 major sites and the “Geologic Repository Disposal” site (GRD).

Remote Observational Techniques in Education  

NASA Astrophysics Data System (ADS)

The ability to observe celestial objects remotely is making a major impact into classroom access to astronomical instrumentation previously impossible to encorporate into curriculum. Two programs, Radio Jove and Telescopes In Education have made important contributions in this field. Radio JOVE is an interactive, hands-on, educational activity for learning the scientific method through the medium of radio observations of Jupiter, the Sun, and the galactic radio background. Students build radio receivers from relatively inexpensive non-profit kits (about \\$125 plus shipping) and use them to record data, analyze the data, and share the results with others. Alternatively, for no cost, the students can record and analyze data from remote radio receivers connected to the web. The projects are useful adjuncts to activities in optical observing since students should recognize that we learn about the universe through more than just the optical spectrum. The projects are mini-electronics courses and also teach about charged particles and magnetic fields. The Radio JOVE web site (http://radiojove.gsfc.nasa.gov) should be consulted for further information. The NASA-sponsored Telescopes In Education (TIE) network (http://tie.jpl.nasa.gov) has been wildly successful in engaging the K-12 education community in real-time, hands-on, interactive astronomy activities. Hundreds of schools in the US, Australia, Canada, England, and Japan have participated in the TIE program, remotely controlling the 24-inch telescope at the Mount Wilson Observatory from their classrooms. In recent years, several (approximately 20 to date) other telescopes have been, or are in the process of being, outfitted for remote use as TIE affiliates. These telescopesare integrated seamlessly into one virtual observatory providing the services required to operate this facility, including a scheduling service, tools for data manipulation, an online proposal review environment, an online "Virtual TIE Student Ap J" for publication of results, and access to related educational materials provided by the TIE community.

MESA: Mercator scheduler and archive system  

NASA Astrophysics Data System (ADS)

We have developed an observing scheduling and archive system for the 1.2 meter Mercator Telescope. The goal was to optimize the specific niche of this modern small telescope in observational astrophysics: the building-up of long-term time series of photometric or high-resolution spectroscopic data with appropriate sampling for any given scientific program. This system allows PIs to easily submit their technical requirements and keep track of the progress of the observing programmes. The scheduling system provides the observer with an optimal schedule for the night which takes into account the current observing conditions as well as the priorities and requirements of the programmes in the queue. The observer can conveniently plan an observing night but also quickly adapt it to changing conditions. The archiving system automatically processes new files as they are created, including reduced data. It extracts the metadata and performs the normalization. A user can query, inspect and retrieve observing data. The progress of individual programmes, including timeline and reduced data plots can be seen at any time. Our MESA project is based on free and open source software (FOSS) using the Python programming language. The system is fully integrated with the Mercator Observing Control System1 (MOCS).

Simulation of an Optimum Multilevel Dynamic Round Robin Scheduling Algorithm  

NASA Astrophysics Data System (ADS)

CPU scheduling has valiant effect on resource utilization as well as overall quality of the system. Round Robin algorithm performs optimally in time shared systems, but it performs more number of context switches, larger waiting time and larger response time. In order to simulate the behavior of various CPU scheduling algorithms and to improve Round Robin scheduling algorithm using dynamic time slice concept, in this paper we produce the implementation of new CPU scheduling algorithm called An Optimum Multilevel Dynamic Round Robin Scheduling (OMDRRS), which calculates intelligent time slice and warps after every round of execution. The results display the robustness of this software, especially for academic, research and experimental use, as well as proving the desirability and efficiency of the probabilistic algorithm over the other existing techniques and it is observed that this OMDRRS projects good performance as compared to the other existing CPU scheduling algorithms.

Wait-time, classroom discourse, and the influence of sociocultural factors in science teaching  

NASA Astrophysics Data System (ADS)

Wait-time, a variable related to questioning in a teaching-learning situation, has been found to have implications for the inquiry mode of science teaching especially in Western classroom environments. Aside from the fact that the literature is very sparse in this area about what obtains in developing countries, nothing appears to be available with regard to how wait-time interacts with the sociocultural factors within non-Western science classrooms. In a non-Western country such as Nigeria where most science programs in schools are inquiry-oriented, do teachers take notice of, and effectively use, wait-time in the teaching-learning process? Are science teachers able to effectively use the mediating role of sociocultural factors in science teaching in a traditional environment which expects children to be seen only and not heard? The main purpose of this study was to investigate the wait-time of Nigerian integrated science teachers in relation to the amount of students' participation in inquiry. This study also investigated the relationship between wait-time and sociocultural attitudinal factors prevalent in traditional societies. The instruments used for data collection were the Hough's Observational Schedule and a modified version of the Socio-Cultural Environment Scale (SCES); a stop-watch was used to measure the wait-time of audio-recorded integrated science lessons of 37 integrated science teachers from selected junior secondary schools in Kaduna State, Nigeria. The results showed that the average wait-time TT and wait-time ST of the integrated science teachers was 3.0 seconds and 0.7 seconds, respectively. The study reported the amount of student participation in the student-teacher classroom discourse to be very low. Wait-time was also shown to have a strong relationship with sociocultural factors of authoritarianism, goal structure, societal expectation, and traditional worldview. The pedagogical and curricular implications of the results have been highlighted.

We evaluated the effects of rewarded scheduled toilet sits on non-retentive encopretic behavior of an elementary-school student receiving services for serious emotional disturbance. A multidisciplinary team implemented the 8-week intervention using a multiple baseline across settings design. The results showed an increase in sitting on the toilet and a decline in encopretic episodes in both school and home settings. These findings support the use of a behavioral intervention for children with significant behavioral disorders within a classroom setting. PMID:22477690

Automated long-term scheduling for the SOFIA airborne observatory  

NASA Astrophysics Data System (ADS)

The NASA Stratospheric Observatory for Infrared Astronomy (SOFIA) is a joint US/German project to develop and operate a gyro-stabilized 2.5-meter telescope in a Boeing 747SP. SOFIA's first science observations were made in December 2010. During 2011, SOFIA accomplished 30 flights in the “ Early Science” program as well as a deployment to Germany. The next observing period, known as Cycle 1, is scheduled to begin in late fall 2012. It includes 46 science flights grouped in four multi-week observing campaigns spread through a 13-month span. Automation of the flight scheduling process offers a major challenge to the SOFIA mission operations. First because it is needed to mitigate its relatively high cost per unit observing time compared to space-borne missions. Second because automated scheduling techniques available for ground-based and space-based telescopes are inappropriate for an airborne observatory. Although serious attempts have been made in the past to solve part of the problem, until recently mission operations staff was still manually scheduling flights. We present in this paper a new automated solution for generating SOFIA's long-term schedules. We describe the constraints that should be satisfied to solve the SOFIA scheduling problem in the context of real operations. We establish key formulas required to efficiently calculate the aircraft course over ground when evaluating flight schedules. We describe the foundations of the SOFIA long-term scheduler, the constraint representation, and the random search based algorithm that generates observation and instrument schedules. Finally, we report on how the new long-term scheduler has been used in operations to date.

Marine sediments in the classroom  

NASA Astrophysics Data System (ADS)

In the present context of global climatic change, studies of the past natural climate variability is critical for the knowledge of the Earth climate mechanism. One of the major climatic reservoir is the ocean which covers more than 70% of the surface of the earth. It exchanges moisture and heat with the atmosphere and plays an important role in the climatic changes at different latitudes. The marine sediments are therefore archives of the past oceanographic/climatic changes. These marine sediments are collected as long cores penetrating into the sediment and therefore giving access to the progressive climatic changes with time. Marine sediments are classically composed of skeleton of micro-organisms and of terrigenous fraction. The main micro-organisms used as tracers of paleoclimatic changes are foraminifera. Their species change with the properties of the water mass in which they live (in particular temperature and salinity). With the aim of showing the students in a classroom how to recognize these species and to reconstruct the past oceanographic changes, "real" sediment has been taken during different cruises in different oceanic basins. We will present here the type of sediments available and the type of analysis/observation which can be made in a class. We will show how to perform the preparation of the samples and what are the possible observations through a binocular microscope. The students will then be able to extract information from their own observation about climate: its variations over time and through the differences between the areas of coring operations. In order to allow this activity to be introduced into your class, a program of distribution of these marine sediments will be proposed and will be presented. A registration form will be available. A limited number of proposals will be accepted and a report of their activity in the classroom will be mandatory a few months after the distribution of samples.

Science Teacher Beliefs and Classroom Practice Related to Constructivism in Different School Settings  

NASA Astrophysics Data System (ADS)

Science teacher beliefs and classroom practice related to constructivism and factors that may influence classroom practice were examined in this cross-case study. Data from four science teachers in two schools included interviews, demographic questionnaire, Classroom Learning Environment Survey (preferred/perceived), and classroom observations and documents. Using an inductive analytic approach, results suggested that the teachers embraced constructivism, but classroom observations did not confirm implementation of these beliefs for three of the four teachers. The most preferred constructivist components were personal relevance and student negotiation; the most perceived component was critical voice. Shared control was the least preferred, least perceived, and least observed constructivist component. School type, grade, student behavior/ability, curriculum/standardized testing, and parental involvement may influence classroom practice.

Science Beyond the Classroom  

NSDL National Science Digital Library

Taking science education beyond the classroom provides learning opportunities and experiences for students that just aren't available within school walls, and Science Beyond the Classroom has a wealth of ideas on how to do it successfully. These carefully selected articles from the NSTA journals Science Scope and Science and Children were gathered into a compendium because of the value of informal science education in providing access to those experiences and in tapping into student interests. Science Beyond the Classroom provides an overview of information and ideas--many of them include step-by-step, teacher-tested instructions and guidelines--that can be easily modified and adapted by teachers and others--scout leaders, club sponsors, parents, and home schoolers among them--who want to nurture enthusiasm for science. An introduc�tion providing background and ideas for using the articles and a list of additional articles and web sites leads each of the five sections: � Extending Science Learning Beyond the Curriculum: Projects and Challenges � Extending Science Learning Beyond the School Building Walls: Using Local Sites � Extending Science Learning Beyond the School Day: Clubs, Camps and Science Expositions � Extending Science Learning to the Family: Take-Home Projects and Family Science Events � Extending Science Learning to Informal Institutions: Museums, Zoos, and Other Field Trips With its potential for engaging student interest, this book aims also at encouraging more students to enter academic fields of science, technology, engineering, and mathematics.

Dynamics in scheduled networks  

NASA Astrophysics Data System (ADS)

When studying real or virtual systems through complex networks theories, usually time restrictions are neglected, and a static structure is defined to characterize which node is connected to which other. However, this approach is oversimplified, as real networks are indeed dynamically modified by external mechanisms. In order to bridge the gap, in this work we present a scheduled network formalism, which takes into account such dynamical modifications by including generic time restrictions in the structure of an extended adjacency matrix. We present some of its properties and apply this formalism to the specific case of the air transportation network in order to analyze its efficiency. Real data are used at this point. We finally discuss on the applicability of this formalism to other complex systems.

Chemical Kiloton Experiment schedules  

NASA Astrophysics Data System (ADS)

The Lawrence Livermore National Laboratory will conduct a large chemical explosion (CE) called the Chemical Kiloton Experiment (CKE) in the Rainier Mesa area of the Nevada Test site. The explosion will involve a 30/70 Emulsion-to-ANFO blend of 1,147,000 kg to supply 1 kt, and is scheduled for January 29. It will be heavily instrumented with close-in, free-field surface seismic and regional seismic measurements. The CKE is located near several DNA-sponsored nuclear explosions (NEs) and will provide a unique opportunity for fundamental studies on explosion phenomenology (for example, CE/NE equivalence), scaling with CEs and NEs, and integration of multiple monitoring methods. This experiment will also address some critical proliferation monitoring problems such as CE masking of NEs, CEs as false alarms, CEs for regional calibration, and on-site inspection.

A classroom experiment to demonstrate ferroelectric hysteresis  

NASA Astrophysics Data System (ADS)

We have developed a classroom experiment suitable for undergraduate students in which they fabricate a ferroelectric capacitor from potassium nitrate and then observe the electrical behavior as the film is cooled through its transition temperature. The experiment can be carried out using a capacitance bridge that is simple to construct and inexpensive. The experiment gives students a hands-on experience with ferroelectric phenomena, a subject of considerable interest from both a fundamental and a technological standpoint.

Teachers were trained in the systematic use of attention and praise to reduce the disruptive classroom behavior of four first-grade children. Observation measures showed a significant improvement from baseline to treatment for these children and no significant changes for same-class controls. While the amount of teacher attention to target children remained the same from baseline to treatment, the proportion of attention to task-relevant behavior of these children increased. Psychological tests revealed no adverse changes after treatment.

Science returns of flexible scheduling on UKIRT and the JCMT  

NASA Astrophysics Data System (ADS)

The Joint Astronomy Centre operates two telescopes at the Mauna Kea Observatory: the James Clerk Maxwell Telescope, operating in the submillimetre, and the United Kingdom Infrared Telescope, operating in the near and thermal infrared. Both wavelength regimes benefit from the ability to schedule observations flexibly according to observing conditions, albeit via somewhat different "site quality" criteria. Both UKIRT and JCMT now operate completely flexible schedules. These operations are based on telescope hardware which can quickly switch between observing modes, and on a comprehensive suite of software (ORAC/OMP) which handles observing preparation by remote PIs, observation submission into the summit database, conditions-based programme selection at the summit, pipeline data reduction for all observing modes, and instant data quality feedback to the PI who may or may not be remote from the telescope. This paper describes the flexible scheduling model and presents science statistics for the first complete year of UKIRT and JCMT observing under the combined system.

We consider the resource-constrained scheduling of loops with interiteration dependencies. A loop is modeled as a data flow graph (DFG), where edges are labeled with the number of iterations between dependencies. We design a novel and flexible technique, called rotation scheduling, for scheduling cyclic DFGs using loop pipelining. The rotation technique repeatedly transforms a schedule to a more compact schedule.

Acoustical evaluation of preschool classrooms  

NASA Astrophysics Data System (ADS)

An investigation was made of the acoustical environments in the Berwick Preschool, Vancouver, in response to complaints by the teachers. Reverberation times (RT), background noise levels (BNL), and in-class sound levels (Leq) were measured for acoustical evaluation in the classrooms. With respect to the measured RT and BNL, none of the classrooms in the preschool were acceptable according to the criteria relevant to this study. A questionnaire was administered to the teachers to assess their subjective responses to the acoustical and nonacoustical environments of the classrooms. Teachers agreed that the nonacoustical environments in the classrooms were fair, but that the acoustical environments had problems. Eight different classroom configurations were simulated to improve the acoustical environments, using the CATT room acoustical simulation program. When the surface absorption was increased, both the RT and speech levels decreased. RASTI was dependent on the volumes of the classrooms when the background noise levels were high; however, it depended on the total absorption of the classrooms when the background noise levels were low. Ceiling heights are critical as well. It is recommended that decreasing the volume of the classrooms is effective. Sound absorptive materials should be added to the walls or ceiling.
