A unified approach for multi objective redundancy allocation problem

This paper represents to solve the redundancy allocation problem (RAP) occurring in optimization technique. The past research of RAP is basically single objective, which is focused on optimization of only one objective. We can genuinely combine more important aspects like cost, volume and weight to this which will lead to a multiple objective redundancy allocation problem (MORAP). The objective of this paper is to solve the RAP problem and makes it more comfortable for use. The most important technique of this paper is Multi-objective evolutionary algorithms (MOEA) that can be used to optimize the solutions in MORAP. From the experimental results, it is obvious that MOEA will give better compromising solutions in the form of non-dominated solutions instead of subsequent joining of a number of single objective approaches.
Performance Analysis with HPX

With High Performance Computing moving towards Exascale, where parallel applications will be required to run concurrently on millions of cores, every part of the computational model must perform ideally to achieve optimal performance. The task scheduler is one of such entities that could be enhanced to runtime application prerequisites. Not only the overheads associated with task scheduling vary depending on the task size but also are affected by the different schedulers used. One of the best strategies used to ameliorate performance and to decrease the overheads would be to adapt the scheduler to the application’s needs or to vary the task size or a combination of both. In this work, we show how scheduling overheads vary with the different types of schedulers used in the High Performance ParalleX (HPX) runtime system. In addition to this, we show how the different schedulers perform with varying task size. This performance analysis focuses on understanding how the different schedulers perform for a specific HPX benchmark in turn helping us to settle on a scheduler that could give optimal performance. HPX is an ideal experimental platform as it makes use of asynchronous fine-grained task scheduling and incorporates a dynamic performance modeling capability. In addition to this, HPX offers performance counter capabilities with which we can characterize scheduling overheads.
ThermalSim: A Thermal Simulator for Error Analysis

Researchers have extensively explored predictive control strategies for controlling heating, ventilation, and air conditioning (HVAC) units in commercial buildings. Predictive control strategies, however, critically rely on weather and occupancy forecasts. Existing state-of-the-art building simulators are incapable of analysing the influence of prediction errors (in weather and occupancy) on HVAC energy consumption and occupant comfort. In this paper, we introduce ThermalSim, a building simulator that can quantify the effect of prediction errors on the HVAC operations. ThermalSim has been implemented in C/C++ and MATLAB. We describe its design, use, and input format.
Study of Introducing Competition in Retail Supply of Electricity across Developed Countries and its Framework for India

The Electricity Act 2003 in India brought a competition in generation segment resulting into a wholesale market. With the absence of segregation of wire and supply of Discoms in the existing policy for introducing competition in retail supply, a fair competition environment in distribution of electricity is yet to be flourished. An initiative of Government of India through Electricity (Amendment) Bill, 2014 advocated introduction of separation of wire and content of Discoms. In order to provide more clarity to various States of India for its implementation, Forum of Regulators developed a model rollout plan for introducing competition in retail sale of electricity. This paper evaluates a model rollout plan developed by Forum of Regulators vis-à-vis international experience on introducing competition in retail supply of electricity by method of separating wire from the content of supply in distribution of electricity. Five international experiences, viz. UK, Australia, Philippines, New Zealand and California were chosen for a detailed study of their electricity reform processes with criteria of segregating wire and supply functions of Disoms and having mixed experience of success and failures. Based on various international experiences on key issues of electricity retail supply competition , a framework for India as suggested by Forum of Regulators introducing competition in retail electricity supply have been analysed.
Awareness of Suicide Risk and Communication Between Health Care Professionals and Next‐of‐Kin of Suicides in the Month Before Suicide

Based on psychological autopsy data, the study compared awareness of suicide risk in the deceased among next-of-kin (NOK) and health care professionals (HCPs), and communication between these two groups in the month before death. The NOKs had significantly more knowledge about the decedent's suicide warning signs than the HCPs (90.5% vs. 44.6%). Contact between NOK and HCP was initiated more often by the family than the HCPs (29.4% vs. 5.9%). The study found communication gaps between HCPs and NOK and stresses the need for suicide prevention strategies strengthening communication between these two groups.
Development of On-line Shopping Mart System for Developing Countries

In Nigeria and most Developing Countries, buying and selling of goods are done in a market. This situation is faced with diverse problems. These problems include the need for buyers and sellers to come into physical contact, the necessary need for potential buyers to visit the shop and non-flexibility in time usage. In order to overcome these problems, an On-line Shopping Mart system (EasyShop) is developed.This is done by developing an information system database that stores and processes information about buyer’s orders, sellers and products. The database is queried to respond to clients’ requests. It is updated with clients’ requests. The system is a web application designed using ASPX /Microsoft C# . NET programming language and the database is designed by using MySQL Server.The proposed system can be used for shopping activities by developing countries. It is an easy to use information system that will assist both buyers and sellers shop effectively.
Virtual Facility at Fermilab: Infrastructure and Services Expand to Public Clouds

In preparation for its new Virtual Facility Project, Fermilab has launched a program of work to determine the requirements for running a computation facility on-site, in public clouds, or a combination of both. This program builds on the work we have done to successfully run experimental workflows of 1000-VM scale both on an on-site private cloud and on Amazon AWS. To do this at scale we deployed dynamically launched and discovered caching services on the cloud. We are now testing the deployment of more complicated services on Amazon AWS using native load balancing and auto scaling features they provide. The Virtual Facility Project will design and develop a facility including infrastructure and services that can live on the site of Fermilab, off-site, or a combination of both. We expect to need this capacity to meet the peak computing requirements in the future. The Virtual Facility is intended to provision resources on the public cloud on behalf of the facility as a whole instead of having each experiment or Virtual Organization do it on their own. We will describe the policy aspects of a distributed Virtual Facility, the requirements, and plans to make a detailed comparison of the relative cost of the public and private clouds. This talk will present the details of the technical mechanisms we have developed to date, and the plans currently taking shape for a Virtual Facility at Fermilab.

Robust Solutions for the DWDM Routing and Provisioning Problem: Models and Algorithms

The dense wavelength division multiplexing routing and provisioning problem with uncertain demands and a fixed budget is modeled as a multicriteria optimization problem. To obtain a robust design for this problem, the primary objective is to minimize a regret function that models the total amount of over and/or under provisioning in the network resulting from uncertainty in a demand forecast. Point-to-point demands are given by a set of scenarios each with a known probability, and regret is modeled as a quadratic function. The secondary objective is to minimize the equipment cost that achieves the optimal value for regret. We propose a two-phase robust optimization strategy that uses a pair of integer linear programs having a large number of continuous variables, but only two integer variables for each link. In an empirical study, the two-phase robust optimization strategy is compared to alternative techniques using a mean-value model, a worst-case model, and a two-stage stochastic integer program with recourse model. Both the worst-case model and the stochastic programming model exhibited a bias toward low-cost designs (well below the budget) at the expense of high expected over/under provisioning. For a tight budget, the mean-value model fails miserably yielding no design for comparison. The two-phase robust strategy produces the optimal design for a given budget that is the best compromise between expected regret and equipment cost.
RPE during prolonged cycling with and without carbohydrate ingestion in boys and men.

PURPOSE To examine the effect of prolonged cycling on ratings of perceived exertion (RPE) in boys and men and whether carbohydrate (CHO) ingestion would lower RPE during exercise. METHODS Ten boys (9-10 yr) and 10 men (20-25 yr) cycled for 60 min at approximately 70% VO2peak on two occasions. In a double-blind, counterbalanced design, a total volume of 24 mL.kg(-1) body mass of either a 6% CHO-electrolyte (CT) or flavored water (WT) beverage was consumed intermittently before and during exercise in each trial. Oxygen consumption (VO2), ventilation (VE), respiratory rate (RR), RPE (Borg's 6-20 scale), and heart rate (HR) were recorded periodically throughout exercise. Plasma glucose (GLU) was determined before and after exercise. RESULTS Postexercise GLU was not different between age groups but higher (P<0.001) during CT (5.6 +/- 0.2 mmol.L(-1)) compared with WT (4.7 +/- 0.1 mmol.L(-1)). CHO ingestion had no effect (P>0.05) on VO2, VE, RR, or RPE in either group. RR during exercise was higher (P<0.01) in boys (39.0 +/- 2.2 breaths.min(-1)) than in men (30.9 +/- 1.3 breaths.min(-1)). HR was slightly higher (P=0.047) during CT (160 +/- 3 beats.min(-1)) compared with WT (156 +/- 4 beats.min(-1)) and increased less over time (P<0.01) in boys compared with men. RPE at 5 min of exercise was similar (P>0.05) between boys (11.8 +/- 0.7) and men (12.0 +/- 0.7) but increased faster (P<0.01) over time in boys. The average exercise RPE was higher (P<0.01) in boys (15.8 +/- 0.5) than in men (14.0 +/- 0.4). CONCLUSIONS The higher and faster increase in RPE during exercise in boys, compared with men, may reflect a sensitivity to RR that outweighed any effect of CHO ingestion on RPE.
Analyse des représentations graphiques de l'information : extensions aux représentations tridimensionnelles

Le probleme du traitement de l'information par l'utilisateur est au cur d'un certain nombre d'applications. De ce fait, la representation graphique de l'information est une solution frequemment retenue et se trouve alors au centre des problemes de conception d'interfaces utilisateur. Il existe dans ce domaine de nombreuses tentatives qui visent a experimenter de nouvelles techniques de representation. C'est a ces systemes que nous nous sommes plus particulierement interesses. Les innovations presentees dans la litterature sont souvent recensees sous le terme de techniques de visualisation. Ce vocable flou recouvre dans les faits un vaste champ d'activites. La reutilisation de ces techniques, au sens de l'application des propositions qui sont faites en matiere de representation graphique a d'autres domaines que celui pour lesquels elles ont ete concues, semble difficile. La caracterisation que nous proposons nous permet de decrire a la fois la nature des informations transcrites dans la representation graphique et la maniere dont celle-ci est construite. Ce travail permet egalement de mettre en evidence le processus de conception d'une representation graphique et les solutions envisageables a chaque etape de ce processus. Cette caracterisation des representations graphiques nous conduit ensuite a considerer l'un des points mis en evidence : l'utilisation d'un espace tridimensionnel pour la representation graphique des informations. Ce theme constitue la seconde partie de notre travail. Envisager l'utilisation de l'espace a trois dimensions pour la representation graphique conduit a considerer deux aspects : tout d'abord une analyse de l'espace tridimensionnel en tant qu'espace de representation, puis une analyse de l'espace tridimensionnel en tant qu'espace de construction des representations graphiques.
Detection and genotyping of enteroviruses in cerebrospinal fluid in patients in Victoria, Australia, 2007–2013

Genotyping by VP1 fragment polymerase chain reaction (PCR) and nucleic acid sequencing to detect enterovirus (EV) genotypes was performed directly on 729 EV PCR positive cerebrospinal fluid (CSF) samples collected between 2007 and 2012 from Victorian hospital inpatients. The overall genotype identification rate from CSF‐positive material was 43%. The four most common genotypes identified were Echovirus 6 (24%), Echovirus 30 (17%), Echovirus 25 (10%), and Coxsackievirus A9 (10%), together comprising 61% of all EVs typed. The seasonal distribution of all EVs identified followed the recognized pattern of mainly summer epidemics. Three of the four predominant genotypes were present in each of the 6 years in which the study was conducted, with 20 other EV genotypes also detected, often in only a single year. Genotyping of EVs directly in CSF is faster, simpler and more sensitive than traditional virus neutralization assays performed on EV positive samples. J. Med.

The Use of Statistical Process Control Charts in Hospital Epidemiology

Hospital epidemiologists rely on sound scientific and analytical principles in the conduct of surveillance, studies, investigations, etc. The demonstration of differences in occurrence of events (eg, nosocomial infections) in different time periods generally has used traditional hypothesis testing statistical models. However, repetitive hypothesis testing is impractical for frequent analysis of accumulating data, especially when there is no apparent outbreak. Clearly, a statistical procedure that simplifies hypothesis testing to detect acute variations in certain occurrences is desirable. Ongoing analysis of trends also would be desirable. Many United States hospitals have espoused continuous quality improvement (CQI) or similarly identified programs as a means to improve both patient care and operating efficiency. With this trend, the scientific method has become interjected into all aspects of patient management, and no longer is confined to formal research studies. Many scientific quality management techniques that long have been used in industrial settings have been applied to healthcare settings. Noteworthy is the use of statistical methods to describe the variation in processes, which is known as statistical process control (SPC). The term statistical quality control (SQC) often is used interchangeably, but some authors refer to SQC only when statistical methods also are used to improve a process. This article will describe the basic theory and simple application of SPC in hospital epidemiology.
The protozoan parasite Trichomonas gallinae causes adult and nestling mortality in a declining population of European Turtle Doves, Streptopelia turtur

SUMMARY Studies incorporating the ecology of clinical and sub-clinical disease in wild populations of conservation concern are rare. Here we examine sub-clinical infection by Trichomonas gallinae in a declining population of free-living European Turtle Doves and suggest caseous lesions cause mortality in adults and nestlings through subsequent starvation and/or suffocation. We found a 100% infection rate by T. gallinae in adult and nestling Turtle Doves (n = 25) and observed clinical signs in three adults and four nestlings (28%). Adults with clinical signs displayed no differences in any skeletal measures of size but had a mean 3·7% reduction in wing length, with no overlap compared to those without clinical signs. We also identified T. gallinae as the suggested cause of mortality in one Red-legged Partridge although disease presentation was different. A minimum of four strains of T. gallinae, characterized at the ITS/5·8S/ITS2 ribosomal region, were isolated from Turtle Doves. However, all birds with clinical signs (Turtle Doves and the Red-legged Partridge) carried a single strain of T. gallinae, suggesting that parasite spill over between Columbidae and Galliformes is a possibility that should be further investigated. Overall, we highlight the importance of monitoring populations for sub-clinical infection rather than just clinical disease.

Applications of diffusion-weighted magnetic resonance imaging in renal cell carcinoma

Diffusion-weighted MRI (DW-MRI) has received more attention recently, especially from uroradiologists, owing to its role in the characterization of renal lesions. Moreover, the apparent diffusion coefficient (ADC), a value calculated based on DW-MRIs, has been used to analyze renal lesions quantitatively. However, many factors influence the accuracy of the ADC value calculation during the DW-MRI procedure. In addition, it is of great interest whether DW-MRI is superior to more conventional dynamic contrast-enhanced (DCE)-MRI for the characterization of renal lesions, or whether DW-MRI combined with DCE-MRI may provide more valuable information. Here we review state-of-the-art DW-MRI for the evaluation of renal cell carcinomas, discuss factors that influence the calculation of ADC maps, examine the impact of field strength on ADC values and, finally, compare DW-MRI and DCE-MRI for imaging renal lesions.
The role of capital structure in the U.S. enterprises – the case of Californian small businesses

Small businesses face acute problems in accessing external funds. There is a large interest in finding the optimal capital structure and understanding the access of firms to finance, particularly in the process of financing small enterprises. Small firms tend to be bank dependent for external funds and the adequate capital structure is of crucial importance. This paper is concerned with the role of capital structure in the U.S. small enterprises. The data and statistical analysis derived from the empirical research and empirical study that was done in California are discussed. The paper presents the literature review on the capital structure and its theories. Moreover, it identifies the most important factors influencing the optimal capital structure. Last but not least is a short presentation and analysis of the association between particular empirical research questions regarding the capital structure and selected external factors.
A collaborative Brain-Computer Interface for improving group detection of visual targets in complex natural environments

Detecting a target in a complex environment can be a difficult task, both for a single individual and a group, especially if the scene is very rich of structure and there are strict time constraints. In recent research, we have demonstrated that collaborative Brain-Computer Interfaces (cBCIs) can use neural signals and response times to estimate the decision confidence of participants and use this to improve group decisions in visual-matching and visual-search tasks with artificial stimuli. This paper extends that work in two ways. Firstly, we use a much harder target detection task where observers are presented with complex natural scenes where targets are very difficult to identify. Secondly, we complement the neural and behavioural information used in our previous cBCIs with physiological features representing eye movements and eye blinks of participants in the period preceding their decisions. Results obtained with 10 participants indicate that the proposed cBCI improves decision errors by up to 3.4% (depending on group size) over group decisions made by a majority vote. Furthermore, results show that providing the system with information about eye movements and blinks further significantly improves performance over our best previously reported method.
Human Masticatory Muscle Forces during Static Biting

Muscle forces determine joint loads, but the objectives governing the mix of muscle forces involved are unknown. This study tested the hypothesis that masticatory muscle forces exerted during static biting are consistent with objectives of minimization of joint loads (MJL) or muscle effort (MME). To do this, we compared numerical model predictions with data measured from six subjects. Biting tasks which produced moments on molar and incisor teeth were modeled based on MJL or MME. The slope of predicted vs. electromyographic (EMG) data for an individual was compared with a perfect match slope of 1.00. Predictions based on MME matched best with EMG activity for molar biting (slopes, 0.89-1.16). Predictions from either or both models matched EMG results for incisor biting (best-match slopes, 0.95-1.07). Muscle forces during isometric biting appear to be consistent with objectives of MJL or MME, depending on the individual, biting location, and moment.
Impacts of ASEAN +3 integration on Vietnam's trade flows in fishery sector

This research examines the impacts of FTAs in ASEAN+3 trade integration on Vietnam‟s trade flow in fisheries sector based on a gravity model and panel data for years from 2001 – 2012. Estimates indicate that economic size, market size, distance and real exchange rate of Vietnam and 43 trade partners play a major role in bilateral trade in fisheries sector between Vietnam and these coutries. Meanwhile, the results also reveal that the opening and trade liberlization in ASEAN+3 bring large trade creation effects in fisheries sector especially AFTA, AKFTA, ACFTA. Howerver, some other FTAs such as VJEPA and AJCEP have thus far not been shown to have impact on trade flow in fisheries sector.
