An agent-based production control framework for multiple-line collaborative manufacturing

This research focuses on constructing an agent-based collaborative production control framework that is capable of conducting scheduling and dispatching functions among production entities, as well as within them, in a collaborative manufacturing environment. The proposed framework utilizes autonomous agent and weighted functions for distributed decision-making while all agents work in active and collaborative ways to help each other make decisions. This collaborative control framework is capable of realizing and seeking balances among heterogeneous objectives of the production entities within a collaborative manufacturing system. The agents in this control framework were constructed with an object-oriented prospective so that a production entity can join or depart from the control scheme without affecting the rest of the framework. Simple index values, instead of detailed data, were used for information exchange among agents. This can greatly reduce the communication and computation load of the control system and keep detailed production information confidential while the agents in the system could belong to different companies. In this research we created a simulation model of a real-world multi-line elevator manufacturing system as the test bed to evaluate the performance of the proposed control framework. Two other control strategies with different levels of collaboration were applied to the simulation model to compare and evaluate the performances of the proposed control strategy. Results of the simulation show that multiple objectives of the production entities can be realized.
An Abstraction to Support Design of Deadlock-free Routing Algorithms for Large and Hierarchical NoCs

New techniques and tools will be required to handle the complexity of on-chip networks required for building multi-core platforms with hundreds of cores. The concepts of hierarchy and abstraction, which have been useful in the design and analysis of electronic systems, will also be useful in the network design area. In this paper we propose an abstraction for networks to reduce the complexity of design and analysis of deadlock-free routing for large and hierarchical networks. Raising the level of abstraction necessarily leads to loss of some information. This loss of information in turn often results in loss of performance of the design as compared to when the network was considered at a lower level of abstraction. We show that our proposed abstraction leads to very small loss of performance. In particular, we show that average increase in communication distance (hops) is low or comparable to non-abstract design. Our simulation-based evaluation indicates that abstract routing design has no negative impact on message latency. On the contrary, abstract routing shows a slight advantage, which increases if more network communication is local and confined within subnets.
Enforcing fairness in a live-streaming system

We describe a practical auditing approach designed to encourage fairness in peer-to-peer streaming. Auditing is employed to ensure that correct nodes are able to receive streams even in the presence of nodes that do not upload enough data (opportunistic nodes), and scales well when compared to previous solutions that rely on tit-for-tat style of data exchange. Auditing involves two roles: local and global. Untrusted local auditors run on all nodes in the system, and are responsible for collecting and maintaining accountable information regarding data sent and received by each node. Meanwhile, one or more trusted global auditors periodically sample the state of participating nodes, estimate whether the streaming quality is satisfactory, and decide whether any actions are required. We demonstrate through simulation that our approach can successfully detect and react to the presence of opportunistic nodes in streaming sessions. Furthermore, it incurs low network and computational overheads, which remain fixed as the system scales.
Potential for Psorophora columbiae and Psorophora ciliata Mosquitoes (Diptera: Culicidae) to Transmit Rift Valley Fever Virus

ABSTRACT Rift Valley fever virus (RVFV) continues to pose a threat to much of the world. Unlike many arboviruses, numerous mosquito species have been associated with RVFV in nature, and many species have been demonstrated as competent vectors in the laboratory. In this study, we evaluated two field-collected Psorophora species, Psorophora columbiae (Dyar and Knab) and Psorophora ciliata (F.) for their potential to transmit RVFV in North America. Both species were susceptible to infection after feeding on a hamster with a viremia of 107 plaque-forming units/ml, with infection rates of 65 and 83% for Ps. columbiae and Ps. ciliata, respectively (with nearly all specimens becoming infected when feeding on a hamster with a higher viremia). However, both species had a significant salivary gland barrier, as only 2/35 Ps. columbiae and 0/3 Ps. ciliata with a disseminated infection transmitted virus by bite. Despite the presence of the salivary gland barrier, due to the very high population that can occur and its propensity to feed on large mammals, Ps. columbiae might play a role in amplifying RVFV should that virus be introduced into an area where this species is common.
Analysis of Data Collected by RDS Among Sex Workers in 10 Brazilian Cities, 2009: Estimation of the Prevalence of HIV, Variance, and Design Effect

Background:Respondent-driven sampling (RDS) is a chain-referral method that is being widely used to recruit most at-risk populations. Because the method is respondent driven, observations are dependent. However, few publications have focused on methodological challenges in the analysis of data collected by RDS. Methods:In this article, we propose a method for estimating the variance of the HIV prevalence rate, based on the Markov transition probabilities and within recruitment cluster variation. The method was applied to a female commercial sex workers study carried out in 10 Brazilian cities in 2008. Both the inverse of network size and the size of the city were considered in the estimation of overall sampling weights. The study included a behavior questionnaire and rapid tests for HIV and syphilis. Results:About 2523 interviews were conducted successfully, excluding the seeds. Results show a positive homophily between recruits for those HIV+; HIV- recruiters selected HIV+ recruits 4% of the time; HIV+ recruiters selected other HIV+ recruits 19.6% of the time, about 5 times higher. The prevalence rate was estimated at 4.8% (95% confidence interval: 3.4 to 6.1), and a design effect of 2.63. Conclusions:Using statistical methods for complex sample designs, it was possible to estimate HIV prevalence, standard error, and the design effect analytically. Additionally, the proposed analysis lends itself to logistic regression, permitting multivariate models. The stratification in cities has proved suitable for reducing the effect of design and can be adopted in other RDS studies, provided the weights of the strata are known.

Attentional refocusing between time and space in older adults:investigation of neural mechanisms and relation to driving

Older adults have a disproportionately high risk of causing collisions at intersections and causing collisions by failing to notice surrounding road signs or signals. Collisions caused by older drivers seem to result from attentional failures. There is limited research exploring the ability to refocus from orienting attention to events changing in time (i.e. temporal attention) to distributing attention spatially (i.e. spatial attention), a process that is particularly important while driving and, if impaired,could cause collisions. The aims of the project were firstly to assess whether the ability to refocus attention from time to space changes throughout the adult lifespan when assessed with a computer based task and in an ecologically valid scenario during simulated driving, secondly, to use magnetoencephalography (MEG) to identify changes to neural mechanism that might explain difficulties in attentional refocusing, and finally, use mobile electroencephalography to explore the neural mechanisms involved in attentional refocusing while driving. Results demonstrated age related declines in the ability to refocus attention from time to space both in a computer-based task and during simulated driving. MEG recorded in a computer-based attention refocusing task revealed that, compared to younger adults, older and middle-aged adults displayed task-related theta deficits in lower level visual processing areas, and instead, displayed compensatory increases in theta power and phase-related connectivity across frontal regions. Increased frontal lobe recruitment likely reflects enhanced top-down attention to cope with impaired lower level attention mechanisms,supporting compensatory recruitment models of ageing. During simulated driving, older participants displayed slower driving speeds and weaker beta desynchronization in preparation to read a road sign, instead displaying a stronger theta power increase in response to the road sign, further demonstrating neural and behavioural compensatory strategies that are only partially successful.Findings warrant the development of a training programme to improve attentional refocusing between time and space while driving.
Robust person identification system using iris

Human iris provides a unique structure suitable for non-invasive biometric assessment. The irises are as distinct as fingerprints even for twins. In this paper a robust system for person identification is presented that uses a technique of localization, alignment, feature extraction, and matching the features of irises. A CASIA iris database has been used to observe the performance of the proposed iris recognition system. The results show that proposed method is quite effective.

Reducing Packet Delay through Filter Merging

The use of packet filters has increased considerably due to the growth of Internet users and network services. A number of header fields must be examined by the filter, causing delay for each packet processed. The problem is compounded when considering multiple filters across a network. To maximize network performance, it would be desirable to minimize the number of packet filters for each path across a domain. Due to the interactions of rules between filters, the underlying network topology and the actions of dynamic routing protocols, it is computationally infeasible to implement this strategy by collectively considering all packet filters across the network. A simpler approach is the elimination of a filter by merging two filters on a common network segment. This work presents a novel packet filter merging algorithm using decision diagrams. A large number of practical and simulated experimental results are provided to demonstrate the effectiveness of the technique and possible enhancements are considered in the conclusion. The results show an average 20% performance improvement can be obtained using the technique.
Plasticity of Intact Rubral Projections Mediates Spontaneous Recovery of Function after Corticospinal Tract Injury

Axons in the adult CNS fail to regenerate after injury, and therefore recovery from spinal cord injury (SCI) is limited. Although full recovery is rare, a modest degree of spontaneous recovery is observed consistently in a broad range of clinical and nonclinical situations. To define the mechanisms mediating spontaneous recovery of function after incomplete SCI, we created bilaterally complete medullary corticospinal tract lesions in adult mice, eliminating a crucial pathway for voluntary skilled movement. Anatomic and pharmacogenetic tools were used to identify the pathways driving spontaneous functional recovery in wild-type and plasticity-sensitized mice lacking Nogo receptor 1. We found that plasticity-sensitized mice recovered 50% of normal skilled locomotor function within 5 weeks of lesion. This significant, yet incomplete, spontaneous recovery was accompanied by extensive sprouting of intact rubrofugal and rubrospinal projections with the emergence of a de novo circuit between the red nucleus and the nucleus raphe magnus. Transient silencing of this rubro–raphe circuit in vivo via activation of the inhibitory DREADD (designer receptor exclusively activated by designer drugs) receptor hM4di abrogated spontaneous functional recovery. These data highlight the pivotal role of uninjured motor circuit plasticity in supporting functional recovery after trauma, and support a focus of experimental strategies on enhancing intact circuit rearrangement to promote functional recovery after SCI.

Dualité entre espace des variables et espace des sujets

The Implicative Statistics Analysis tends to quantify, through the concepts of typicality and contribution, the quality of the relationship that links each subject to the implicative graph ways or to the classes for similarity hierarchies and to the implicative cohesion ones. These quantitative formulas conversely provide a metric structure for the subjects set, allowing comparison of the places of subjects according to the concepts extracted from the first data base. Eventually borderlines subjects may be detected, that is the furthest ones. We use this approach in exploring how elementary school students identify the different subjects they are taught Key-words. Contribution, implicative graph, cohesitive hierarchy, rule, borderline subject, typicality.
Quadratic Stability of Discrete-Time Switched Systems

Quadratic stability of switched systems consisting of a class of m-discrete subsystems is studied. An interval matrix is constructed to transform the discrete-time switched system into interval system. Then, a sufficient condition is presented in terms of linear matrix inequality for the quadratic stability of discrete-time switched systems under arbitrary switching laws. This condition is much simpler than the other methods because it needs only one linear matrix inequality to solve. A numerical example illustrates the effectiveness of the method.
String production at the level of effective field theory

Pair creation of strings in time-dependent backgrounds is studied from an effective field theory viewpoint, and some possible cosmological applications are discussed. Simple estimates suggest that excited strings may have played a significant role in preheating, if the string tension as measured in four-dimensional Einstein frame falls a couple of orders of magnitude below the four-dimensional Planck scale.
Performance comparison of various post processing algorithms

The multiuser detection (MUD) like joint multiuser detection requires more accurate channel estimation than that of single user detection, and hence post processing performed after channel estimation is required to enhance data detection performance. The post processing is to modify the estimated channel coefficients by eliminating the noise only coefficients after the channel estimation. In this paper, various post processing algorithms are introduced and find optimum threshold of each algorithm in the wireless system of the third generation partnership project (3GPP) time division duplex (TDD) mode.
Effect of experiential teaching methodology on personality and entrepreneurial intentions: a proposed framework

Personality has been found to be a primary antecedent to gauge entrepreneurial intentions of an individual. A holistic view of personality is better at understanding this relationship, and may be of more benefit to the individual and assessor. Among students of higher education institutions, entrepreneurial intentions are declining. Individuals with higher entrepreneurial intentions respond better to experiential teaching methodology. In this was higher education institutions may be able to increase the entrepreneurial intentions of the students by using experiential teaching methodologies. This study proposes the use of experiential teaching methodology as a moderator to better understand the relationship between; entrepreneurial proactivity, entrepreneurial creativity, entrepreneurial opportunism and entrepreneurial vision with entrepreneurial intentions. This study also elaborates on the use of entrepreneurial event model as the underpinning theory and human capital theory as the supporting theory to build the proposed research framework.
Dependence of proliferative vascular smooth muscle cells on CD98hc (4F2hc, SLC3A2)

Activation of vascular smooth muscle cells (VSMCs) to migrate and proliferate is essential for the formation of intimal hyperplasia. Hence, selectively targeting activated VSMCs is a potential strategy against vaso-occlusive disorders such as in-stent restenosis, vein-graft stenosis, and transplant vasculopathy. We show that CD98 heavy chain (CD98hc) is markedly up-regulated in neointimal and cultured VSMCs, and that activated but not quiescent VSMCs require CD98hc for survival. CD98hc mediates integrin signaling and localizes amino acid transporters to the plasma membrane. SMC-specific deletion of CD98hc did not affect normal vessel morphology, indicating that CD98hc was not required for the maintenance of resident quiescent VSMCs; however, CD98hc deletion reduced intimal hyperplasia after arterial injury. Ex vivo and in vitro, loss of CD98hc suppressed proliferation and induced apoptosis in VSMCs. Furthermore, reconstitution with CD98hc mutants showed that CD98hc interaction with integrins was necessary for the survival of VSMCs. These studies establish the importance of CD98hc in VSMC proliferation and survival. Furthermore, loss of CD98hc was selectively deleterious to activated VSMCs while sparing resident quiescent VSMCs, suggesting that activated VSMCs are physiologically dependent on CD98hc, and hence, CD98hc is a potential therapeutic target in vaso-occlusive disorders.
