Power-Aware Scheduling for Multiple Feasible Interval Jobs

Time-critical jobs in many real-time applications have more than one feasible interval. Such jobs can be executed in any of their feasible intervals. Given a Multiple Feasible Interval (MFI) job set that is schedulable, energy can be saved by carefully selecting the executing interval for each job. In this paper, we explore the energy minimization problem for real-time systems in which jobs have multiple feasible intervals. The static and dynamic energy management schemes are both investigated to minimize the energy consumption while preserving the systempsilas feasibility. Focusing on the EDF scheduling algorithm, we first study reducing the dynamic power consumption. We show that the static optimal speed assignment problem is NP-Hard and propose a Simulated Annealing (SA) based approach to solve it. Then, we develop an online greedy algorithm to exploit the run-time slacks by ldquofetchingrdquo the eligible job from a hot spot to execute earlier, thus, reducing the dynamic energy consumption. In addition, a leakage-aware version is discussed to improve the overall energy efficiency as well. Simulation results show that all the proposed schemes can achieve significant improvements on energy efficiency while the system remains schedulable.
A role for stem cell factor and c-kit in the murine intestinal tract secretory response to cholera toxin

The role of stem cell factor (SCF) and its receptor (c-kit) in the intestinal secretory response to cholera toxin (CT) was investigated using a ligated intestinal loop model in mice having mutations in the dominant white spotting (W) locus and the steel (Sl) locus. W/Wv mice, which express an aberrant form of the c-kit protein, failed to give an intestinal secretory response after luminal CT challenge. In contrast, W/Wv mice and their control littermates had equivalent intestinal secretory responses to Escherichia coli heat-stable enterotoxin (STa). Sl/Sld mice, which express only a soluble truncated form of SCF, also gave a significantly reduced intestinal secretory response to CT when compared to the secretory response of their littermate controls. The unresponsiveness of W/Wv mice to CT was restricted to the intestinal tract since these mice had foot pad swelling responses to CT challenge that were equivalent to their littermate controls. Restoration of mast cells in W/Wv mice by bone marrow transplantation of control littermate bone marrow did not reverse the CT-unresponsiveness of the intestinal tract. Histological evaluation of the gastrointestinal tract from W/Wv mice showed a normal distribution of enterochromaffin cells (ECC). CT challenge of either ligated intestinal loops from C57B1/6 mice or a mouse intestinal epithelial cell line (MODE-K) resulted in elevated levels of mRNA for SCF. MODE-K cells exposed to CT also had enhanced expression of c-kit. Finally, fluid obtained from CT-challenged ligated intestinal loops from C57B1/6 mice contained significant levels of SCF. Taken together, the above results suggest that CT-induced intestinal secretory responses are dependent upon SCF-c-kit interactions. These interactions appear to be induced as a consequence of CT stimulation of the intestinal tract and may also play a role in the development or functionality of the enteric nervous system.
Technical and timing characteristics of badminton men’s single: comparison between groups and play-offs stages in 2016 Rio Olympic Games

Abstract Badminton match is characterised by intermittent efforts of high intensity and short-duration rallies interspersed by periods of rest. The analyses of technical and timing variables provide important information for understanding the match. The aim of this study was to characterise the technical and timing variables of badminton men’s singles matches and to compare the characteristics between groups and play-offs stages in 2016 Olympic Games. All men’s single matches (groups = 43 and play-offs = 13) from Rio 2016 were used to carry out the post-event analysis. The comparison between phases showed that total time, pause time, points played and shots/rally were significantly higher in the play-offs phase. The frequency of serve, net, smash and total shots was also significantly higher in the play-offs. Only drive presented higher frequency in the group phase. We can conclude that play-offs were more intense than the group stage. Research in this area is relevant for understanding the match and providing information for training planning. The results of this study are important to set the appropriate targeting of workloads in view of the requirements of a match.
Weighted N-gram model for evaluating Machine Translation output

I present the results of an experiment on extending an automatic method of Machine Translation evaluation (BLEU) with weights for the statistical significance of lexical items. I show that this extension gives additional information about evaluated texts; in particular it allows us to measure translation Adequacy, which, for statistical MT systems, is often overestimated by the baseline BLEU method. The proposed model also improves the stability of evaluation scores with a single human reference translation, which increases the usability of the proposed method for practical purposes. The model suggests linguistic a interpretation which develops deeper understanding of human intuitions about translation Adequacy and Fluency.
Modelling and analysis of a smart antenna system with sub-sector dynamic capacity enhancement for mobile telecommunication networks

This paper describes the modelling and analysis of a new smart antenna concept. The paper outlines the rational for the development of a dynamically reconfigurable smart antenna system without greatly increasing the complexity of the system. The subject smart antenna system is developed to offer good coverage and capacity using multiple beams throughout a cell sector and to be able to reconfigure the beam to provide enhanced coverage and maintain capacity in certain areas at reduced, but acceptable coverage throughout the rest of the cell sector of a mobile telecommunication network. The motivation behind the architecture and the methodology used is discussed and then modelling and analysis of the antenna system is presented.
Improvement and AppLication of MKSVM

Grinding production rate (GPR) is a vital index of grinding process. Getting accurate and timely information of GPR is the premise of enhancing grinding efficiency and conducting optimization control. However, for complexity of grinding process, there is no effective method to on-Line predict GPR. On the basis of soft sensor principle, a new sCheme that applying improved mixed-kernel support vector machine (MKSVM) to predict GPR is presented. Meanwhile nesting termination condition genetic algorithm (NTCGA) is proposed to improve the deficiency of MKSVM that there is no effectual way to select parameters of MKSVM's kernel. Furthermore comparison experiments of prediction between the improved MKSVM and traditional support vector machines (SVMs) and radial basis function (RBF) network are conducted. Simulation results show the prediction accuracy of GPR by using the improved MKSVM can meet the demand of practical appLications. And performance of improved MKSVM is much better than other SVMs and RBF network.
Optimized decentralization of composite web services

Composite services are usually specified by means of orchestration models that capture control and data-flow relations between activities. Concrete services are then assigned to each activity based on various criteria. In mainstream service orchestration platforms, the orchestration model is executed by a centralized orchestrator through which all interactions are channeled. This architecture is not optimal in terms of communication overhead and has the usual problems of a single point of failure. In previous work, we proposed a method for executing service orchestrations in a decentralized manner while fulfilling collocation and separation constraints. However, this and similar methods for decentralized orchestration do not seek to optimize the communication overhead between services participating in the orchestration. This paper presents a method for optimizing the selection of services assigned to activities in a service orchestration in terms of QoS properties and communication overhead. The method takes into account the communication cost between pairs of services, the amount of data that these services need to exchange in the orchestration, and the collocation and separation constraints imposed by the service providers.
SEPARATING QUASICONVEX SUBGROUPS OF RIGHT-ANGLED ARTIN

A graph group, or right-angled Artin group, is a group given by a presentation where the only relators are commutators of the generators. A graph group presentation corresponds in a natural way to a simplicial graph, with each generator corresponding to a vertex, and each commutator relator corresponding to an edge. Suppose that G is a graph group whose corresponding graph is a tree and H is a subgroup of G. We show that if H is quasiconvex with respect to either the word metric on G or the CAT(0) metric on the universal cover of the standard complex for G, then H is separable, that is, H is the intersection of finite index subgroups of G. We also discuss some consequences relating to certain 3-manifold groups.
Lacticin 3147, a Broad-Spectrum Bacteriocin Which Selectively Dissipates the Membrane Potential

ABSTRACT Lacticin 3147 is a broad-spectrum bacteriocin produced byLactococcus lactis subsp. lactis DPC3147 (M. P. Ryan, M. C. Rea, C. Hill, and R. P. Ross, Appl. Environ. Microbiol. 62:612–619, 1996). Partial purification of the bacteriocin by hydrophobic interaction chromatography and reverse-phase fast protein liquid chromatography revealed that two components are required for full activity. Lacticin 3147 is bactericidal againstL. lactis, Listeria monocytogenes, andBacillus subtilis; at low concentrations of the bacteriocin, bactericidal activity is enhanced when target cells are energized. This finding suggests that the presence of a proton motive force promotes the interaction of the bacteriocin with the cytoplasmic membrane, leading to the formation of pores at these low lacticin 3147 concentrations. These pores were shown to be selective for K+ ions and inorganic phosphate. The loss of these ions resulted in immediate dissipation of the membrane potential and hydrolysis of internal ATP, leading to an eventual collapse of the pH gradient at the membrane and ultimately to cell death. Our results suggest that lacticin 3147 is a pore-forming bacteriocin which acts on a broad range of gram-positive bacteria.
Changes in Guesswork over Time in Multi-processor Attacks

More and more effort is being spent on security improvements in today’s computer networking environments. However, due to the nature of computer security, there is still a lack of good quantitative assessment methods. Inventing and developing new ways of measuring security are therefore needed in order to more exactly describe, assess, and improve the security of computer environments. One existing quantitative security measure is guesswork. Guesswork gives the average number of guesses in a brute force attack to succeed in breaking an encrypted message. In the current definition of guesswork, it is assumed that the attacker uses a single processor when breaking an encrypted message. An intelligent and motivated attacker will however likely use several processors that run in parallel. This paper formally investigates how guesswork changes over time in multi-processor attacks. The result is applied to three probability distributions, the English alphabet, the geometric and the truncated geometric, in order to illustrate some behaviors.
Family focused strategies for student engagement

Abstract A substantial body of research focuses on student achievement and the characteristics of schools that regularly produce it. While academic achievement is an important variable to measure, student engagement serves as a related and highly influential variable that merits more attention, particularly as it relates to preventative interventions. Student engagement mediates and moderates the relationship between parental influences and academic achievement and school completion. Research examining influences on engagement have often utilized a familiar concept known as parent involvement. Traditional research on parent involvement is school-centric, meaning it is focused on parents’ interactions with and attendance at school events. Unfortunately, this school-centric approach fails to incorporate the conjoint influence of parenting practices, parenting styles, parent-child relationship quality and family structure. New research that examines non-school parental and familial factors influencing student engagement is needed. This article maps the conceptual territory for future research and enhanced practice that is centered on student engagement and the important role that parents and families can play in fostering positive academic outcomes.
Nervous control of the blood pressure in the Atlantic cod, Gadus morhua.

Dorsal (PDA) and ventral aortic blood pressure (PVA) and heart rate (HR) were measured in conscious resting cod, Gadus morhua L. , which has been allowed 24 h recovery from surgery. Plasma adrenalin and nonadrenalin concentrations in these fish were 3.4 and 2.2 nmoll-1 respectively, and thus lower than previously reported values from partially recovered cod. Twenty-four hours after treatment with the adrenergic neurone blocking agent bretylium, PDA was significantly reduced by 17% compared to sham-injected controls, although PVA and heart rate were unaltered. Subsequent alpha-adrenoceptor blockade by phentolamine produced no further fall in PDA and no changes in PVA or HR, provided a 5-h period was allowed to overcome the acute toxic side effects of phentolamine. The effectiveness of the bretylium or phentolamine blockade was confirmed by noting the absence of any vasoconstrictor response during sympathetic nerve stimulation in perfused tails from fish used in the in vivo experiments. Bretylium had no significant effect on the sensitivity of the isolated coeliac artery to adrenalin, but effectively blocked the adrenergic innervation of this artery or the vasculature of the tail. Evidence for a non-selective blockade of non-adrenergic nerves to the heart was also obtained. It is concluded that the adrenergic tonus affecting the dorsal aortic blood pressure in resting cod that have recovered for 24 h following surgery is due solely to an adrenergic nervous tone.
Use of Flattening Filter-Free Photon Beams in Treating Medulloblastoma: A Dosimetric Evaluation

Aim. To evaluate the dosimetric benefits of flattening filter-free (FFF) photon beams in intensity modulated radiation therapy (IMRT) and Rapid Arc (RA) over conventional CSI methods. Methods and Materials. Five patients treated with IMRT using static multileaf collimators (MLC) were randomly selected for this retrospective study. Dynamic MLC IMRT, RA, and conformal therapy (3DCRT) were iterated with the same CT data sets with and without flattening filter photons. Total dose prescribed was 28.80 Gy in 16 fractions. Dosimetric parameters such as D max⁡, D min⁡, D mean, V 95%, V 107%, DHI, and CI for PTV and D max⁡, D mean, V 80%, V 50%, V 30%, and V 10% for OARs were extracted from DVHs. Beam on time (BOT) for various plans was also compared. Results. FFF RA therapy (6F_RA) resulted in highly homogeneous and conformal doses throughout the craniospinal axis. 3DCRT resulted in the highest V 107% (SD) 46.97 ± 28.6, whereas flattening filter (FF) and FFF dynamic IMRT had a minimum V 107%. 6F_RA and 6F_DMLC resulted in lesser doses to thyroid, eyes, esophagus, liver, lungs, and kidneys. Conclusion. FFF IMRT and FFF RA for CSI have definite dosimetric advantages over 3DCRT technique in terms of target coverage and OAR sparing. Use of FFF in IMRT resulted in 50% reduction in BOT, thereby increasing the treatment efficiency.

A Risk-Benefit Driven Architecture for Personal Data Release (Invited Paper)

Personal data storages (PDSs) give individuals the ability to store their personal data in a data unified repository and control release of their data to data consumers. Being able to gather personal data from different data sources (e.g., banks, hospitals), PDSs will play strategic role in individual privacy management. As such, PDS demands for new privacy models for protecting personal data. In this paper, we propose a new technical approach that empowers individuals to better control data in PDS. Particularly, we present a privacy-aware PDS architecture by focusing on two logical data zones based on the categories of personal data. Moreover, we propose a strategy for regulating personal data release that takes in consideration both user preferences and possible risks and benefits of the data release.
Understanding the context of neighborhood parks: a method for public space classification

ABSTRACT Neighborhood parks are recognized as key urban public spaces that serve the social, economic, and environmental needs of adjacent neighborhoods. However, relevant studies primarily focus on the contribution of neighborhood parks as discrete spaces, instead of neighborhood parks as built spaces within an urban context. This research provides a better understanding of the inter-relationships between various urban form measures and an alternative way of constructing public space typology based on the surrounding urban form. The research employs factor and cluster analysis to develop a typology of 150 neighborhood park contexts in the City of Chicago, Illinois. 150-neighborhood park surroundings are classified into six categories based on an understanding of the dimensional structure of urban form elements; however, the Chicago Park District currently classifies them into one broad category. The study also provides guidelines for urban design and physical planning strategies for neighborhood park development.
Does Noise Trading Affect Securities Market Efficiency ?

I investigate the impact of noise trading on securities market efficiency using data from short-horizon Arrow-Debreu securities traded on an online exchange. Using liquidity as a proxy for the amount of noise trading, I show that securities markets with persistently high noise trade exhibit significant pricing anomalies, such as overpricing low probability events and underpricing high probability events. By contrast, markets are remarkably efficient when there is low noise trade or when it is likely that securities’ payoffs will be equal to their fundamental values. These findings are consistent with theoretical models in which rational agents face limits to arbitrage, but inconsistent with frictionless models in which increases in noise trading have no impact or a favorable impact on efficiency. * Please send all comments to tetlock@mail.utexas. edu.

A GPGPU compiler for memory optimization and parallelism management

This paper presents a novel optimizing compiler for general purpose computation on graphics processing units (GPGPU). It addresses two major challenges of developing high performance GPGPU programs: effective utilization of GPU memory hierarchy and judicious management of parallelism. The input to our compiler is a naïve GPU kernel function, which is functionally correct but without any consideration for performance optimization. The compiler analyzes the code, identifies its memory access patterns, and generates both the optimized kernel and the kernel invocation parameters. Our optimization process includes vectorization and memory coalescing for memory bandwidth enhancement, tiling and unrolling for data reuse and parallelism management, and thread block remapping or address-offset insertion for partition-camping elimination. The experiments on a set of scientific and media processing algorithms show that our optimized code achieves very high performance, either superior or very close to the highly fine-tuned library, NVIDIA CUBLAS 2.2, and up to 128 times speedups over the naive versions. Another distinguishing feature of our compiler is the understandability of the optimized code, which is useful for performance analysis and algorithm refinement.
Exxon Valdez Oil Spill Restoration Project Final Report Communication in River Otters : Creation of Variable Resource Sheds for Terrestrial Communities Restoration Project 02593 Final Report

Movements and behavior of animals can result in transfer of nutrients between discrete spatial patches, leading to spatial and temporal variability in resource sheds, modification of nutrient cycling, changes in productivity and in community structure and function, and increases in landscape heterogeneity. In this study, we explored the function of scent-marking at latrines by coastal river otters (Lontra canadensis), through investigating spatial distributions of otters with respect to gender, sociality, and the distribution of their food resources. We then calculated the amounts of nitrogen (N) and phosphorus (P) transported to latrine sites based on otter foraging behavior and the function of scent-marking at latrines. Locations of 55 radio-tagged otters in Prince William Sound, Alaska, USA, were obtained through aerial telemetry over a period of four years. Data on fish densities and marine habitat features were concurrently obtained from scuba transects and aerial surveys. A plastic social organization in river otters resulted in different foraging strategies and scent-marking behaviors. Social otters were more closely associated with schooling fishes and used latrines for intra-group communication, whereas nonsocial otters, which concentrated on intertidal and subtidal fishes, probably signaled mutual avoidance. In contrast, females appeared to use latrines for the defense of territories. Social otters used fewer sites with greater intensity, whereas nonsocial otters used more sites with lower intensity. These different functions of scent-marking and associated behaviors of otters resulted in high variability in nutrient inputs to different latrine sites. Although some sites may receive 2.7 g N·m22·yr21 and 0.4 g P·m22·yr21, others may be fertilized with up to 47.6 g N·m22·yr21 and 6.7 g P·m22·yr21. This spatial variability and the temporal changes in resource sheds is likely to result in the creation of heterogeneous landscape at the land margin.
An adaptive sliding mode controller for buck converter in continuous conduction mode

This paper proposes a new adaptive sliding mode controller for buck converter operating in the continuous conduction mode. Through gain scheduling, the controller is designed to monitor the output loading condition, and adaptively changes its control parameters to give optimal dynamic performances corresponding to any loading variations. Simulations have been carried out to verify the idea. The results show faster transient response and reduced steady state error during over-loaded operation, and improved controller's reliability during underloaded operation, under the adaptive controller.
