Orthogonal Grey Wolf Optimization Algorithm for Task Scheduling in Cloud Environment

— Cloud Computing (CC) is being popularly used by small organizations and startups as a business model in distributed computing environment. In cloud computing, it provides three architectures SaaS, the user tasks are organized and executed with suitable resources PaaS and IaaS to deliver the different types of services to the customer. In cloud, the time complexity of task execution is a common problem. In this paper, an efficient Task Scheduling (TS) technique is proposed namely Orthogonal Grey Wolf Optimization (O-GWO) algorithm. The O-GWO algorithm, schedules the tasks on VMs with minimum execution time. Also, it increases the convergence speed and reduces the Degree of Imbalance (DI) of total task schedule across VMs. An experimental analysis shows that, proposed O-GWO algorithm performance is measured with respect to efficient evaluation metrics such as makespan and Degree of Imbalance. The makespan of proposed O-GWO algorithm is achieved to the extent of 38.20 seconds of enhancement compared to the existing Hybrid Particle Swarm Optimization with Simulated Annealing (HPSO-SA).
Part-time work : policy, practice and resistance in a manufacturing organisation

In Australia, part-time work is seen as the key strategy for enabling employees, primarily women, to better balance work and care responsibilities. However, while almost half of all employed women work on a part-time basis, the take up of part-time work varies considerably across industries and organisations. In retail and hospitality, for example, a significant proportion of jobs are organised on a part-time (and casual) basis. In contrast, in industries like manufacturing, part-time work remains relatively rare even for female employees, with those seeking to reduce their hours of work often having to negotiate on an individual basis with their line supervisor. This article examines the issue of part-time work in a maledominated manufacturing organisation, ManuCo, where relatively few female employees work on a part-time basis. While blue collar employees have an award 'right' to part-time work after return from parental leave, uptake is highest among white collar workers who are dependent on managerial discretion to access part-time work. This article explores the reasons for this apparent paradox and reports on the development of a formal company-wide 'right-to request' part-time work policy. We explore the resistance, both overt and covert, to this initiative and the deeply embedded and gendered organisation of work and working-time that underpins it.
Resale Price Maintenance And Antitrust Policy

Some scholars would legalize all purely vertical resale price maintenance (RPM). They acknowledge that RPM can harm consumers when it facilitates horizontal collusion among manufacturers or dealers. But when RPM is purely vertical (i.e., when it is imposed by a manufacturer acting independently), they argue that it must be procompetitive. Recent theoretical research has shown, however, that purely vertical RPM can reduce economic efficiency. This result occurs when the higher prices and dealer services induced by RPM benefit marginal consumers but substantially reduce the welfare of intramarginal consumers, who would have preferred the product without the services at a lower price. Since these circumstances are empirically plausible, a rule of per se legality may not be appropriate. At the same time, evaluating RPM under the rule of reason might not be workable. Anticompetitive instances of the type described could be difficult to prove. These research findings, therefore, are most consistent with a rule of per se illegality for RPM, with exceptions for situations in which RPM is most likely to be pro-competitive (e.g., new entry).

Static stability characteristics of a systematic series of stern control surfaces on a body of revolution

Abstract : Experiments were conducted to determine the forces and moments due to angle of attack on a representative streamlined body of revolution alternately appended with members of a systematic series of stern control surfaces. The data from these experiments are presented in the report in the form of graphs and tabulations of the nondimensional force and moment coefficients and static stability derivatives. Based on these data empirical mathematical expressions have been developed to predict the contribution of sternplanes to the static stability derivative Zw' when the sternplanes are appended to a submarine whose basic hull is a streamlined body of revolution. A graph is presented for estimating the location of the center of pressure of the forces due to the presence of sternplanes.
Dual broadband design of rectangular slot antenna for 2.4 and 5 GHz wireless communication

A novel dual broadband rectangular slot antenna for 2.4 and 5 GHz wireless local area network (WLAN) is proposed. With the use of a U-shaped strip inset at the centre of the rectangular slot antenna, the obtained impedance bandwidths for two operating bands can reach about 10.6% for the 2.4 GHz band and 33.8% for the 5 GHz band, which cover the required bandwidths of IEEE 802.11b/g (2.4-2.484 GHz) and IEEE 802.11a (5.150-5.950 GHz). Details of the antenna design and experimental results are presented and discussed.

Influence of moisture on device characteristics of polythiophene-based field-effect transistors

We investigated a field-effect transistor (FET) based on a poly(3-n-hexylthiophene) (P3HT) to determine the influence of moisture on device characteristics and thus gain a deep understanding of the mechanism underlying the susceptibility to air of the operation of FETs of this kind. The fundamental output characteristics, which include effective field-effect modulation and saturation behavior in the output current, remained almost the same for every current–voltage profile in a vacuum, N2 and O2. By contrast, operation in N2 humidified with water resulted in enlarged off-state conduction and deterioration in the saturation behavior, in the same manner as that experienced with exposure to room air. We concluded that atmospheric water had a greater effect on the susceptibility of the device operation to air than O2, whose p-type doping activity as regards P3HT caused only a small increase in the conductivity of the active layer and a slight decrease in the field-effect mobility with exposure at ambient pres.
Preparation and in vitro Evaluation of High Performance Fermented Soybean Meal using a mixture of Lactobacillus plantarum, Bacillus subtilis and Saccharomyces cerevisiae

Background: Soybean meal is used in animal feeds as a protein supplement but contains significant amounts of anti-nutritional factors such as trypsin inhibitor that directly inhibit digestion, absorption and utilization of nutrients. Results: Herein, we used solid state batch fermentation of soybean meal using Lactobacillus plantarum, Bacillus subtilis and Saccharomyces cerevisiae alone and in combination to alter the content of anti-nutritional compounds in the meal. A systematic analysis identified a temperature of 40℃, water content of 40 % in a 48 h fermentation that optimized the fermentation according to our goals. The digestibility of the meal increased within 36 h and by 48 h, the free amino acid content increased while glycinin, β-conglycinin and trypsin inhibitor significantly decreased and the indigestible sugars stachyose and raffinose were reduced to undetectable levels. These processes correlated with high levels of lactic acid that were responsible for an overall pH decrease. Conclusions: Bacterial and mixed fermentations increased nutritional content while eliminating anti-nutritional factors and significantly improved the nutritional quality of the soybean meal.
On the Assessment of Equipment Reliability: Trading Data Collection Costs for Precision

The collection of data for quantitative reliability analyses is often a costly process, particularly when field data have to be forwarded to a central point for analysis. In this short note, the authors consider one aspect of these reliability assessments, and show how data collection costs may be considerably reduced by allowing for a relatively low loss of precision in the subsequent analysis. The authors support their remarks with an example in which the two-parameter Weibull distribution is used to describe the times in service of items of equipment; however, this example illustrates principles which are more generally true, and the reader will be able to transfer the conclusions of the discussion to a wide variety of cases.
IEEE 802.11ac sebagai Standar Pertama untuk Gigabit Wireless LAN

WLAN is a technology that currently has been used widely. This technology is considered as a data transferring media technology within the LAN/MAN. To ensure that WLAN technology can be used widely in the whole world, the IEEE has set a standard known as 802.11 to be an international standard for the WLAN technology. This standard was appeared in 1997, and has been revised and improved for several times. This improvement is done to anticipate the rapidly grown WLAN market as well as to keep this technology remains effective, efficient, and reliable at any time. At the beginning of 2014, the IEEE has set 802.11ac-2013 as a new standard for WLANs that operate below 6 GHz to achieve a data rate for up to 7 Gbps. The purpose of this article is to describe comprehensively the IEEE 802.11ac standard as a result of recent changes to the regulatory for WLAN technology which is known as the first standard issued by the IEEE for the gigabit WLANs. This article discusses the goals and objectives to be achieved by 802.11ac standard as well as the parts that have been enhanced significantly both in its PHY and MAC layers. This article will also contrast the differences between the 802.11ac standard and previous WLAN standards. Finally it will also explain the level of compatibility and interoperability of 802.11ac standards with some of previous WLAN standard. Keywords: IEEE, 802.11, 802.11ac, Gigabit WLAN
Effects of Simultaneous Reinforcement of Endocannabinoid and Cholinergic Systems on Anxiety-Like Behavior in Mice

ObjectiveAnxiety behavior is regulated by different neurotransmitter systems. There has been no direct relationship between endocannabinoid and cholinergic systems on anxiety in previous studies. This study investigated the effects of each of these systems separately and simultaneously using Donepezil (Cholinesterase inhibitor) and URB-597 (endocannabinoid degrading enzyme inhibitor) on anxiety-like behavior. MethodEighty-eight male mice were divided into eleven groups (n=8) including control (saline), diazepam (0.3 mg /kg), URB-597 (0.1, 0.3, or 1 mg /kg), donepezil (0.5, 1 or 2 mg/kg) and the combination of the two drugs at low, medium and high doses. All treatments were injected intraperitoneally 30 minutes before the elevated plus maze test. ResultsSeparate administration of URB597, donepezil or diazepam increased the number and time spent of open arms compared to the control group. Concurrent administration of URB and donepezil at low, medium and high doses did not change the number of open arms entries compared to the control group, but they reduced the number of entries to the closed arms. ConclusionsThese results suggest that strengthening any cholinergic or endocannabinoid system has anxiolytic effect similar to diazepam. However, the interaction of these two systems has fewer anxiolytic effects compared to the effects of each alone. It seems that these drugs alone may represent a strategy for the treatment of anxiety disorders.
An Approach to Multivariable Control System Design Using Relay Auto-Tuning

In this paper, a simple method for designing multiloop controllers (see Figure 2) for multivariable system is presented. The procedure is a combination of sequential loop closing and relay auto-tuning often used for tuning PIPID structures. Closed loop stability is guaranteed. Set point responses are improved by introducing set point weighting factors. Some simulation and comparative results are shown for distillation column models commonly used to demonstrate multiloop design procedures.
Macrobend Fiber Optic Transducer For Aerospace Applications

Intensity modulation induced by macrobending in multimode optical fibers is presented as a transduction mechanism for analog position sensing in harsh aerospace environments. The macrobend sensor described herein is most suitable for short stroke applications (1 to 10 mm) where an intrinsic sensor is desired and only moderate linearity is required (< ± 1 %). Macrobend sensors are built and tested with intensity referencing and modal conditioning. The latter allow for sensor replacement without in-situ calibration. The theory, design tradeoffs, and test results of generic intrinsic macrobend position sensors are presented.
A multisensor fusing system on ultrasonic sensors

In the application of an industrial robot, it is often found that the workspace is restructured or changed from time to time, as with for example mining robots or some construction robots. In some special cases, where for example there is dust or insufficient illumination in the environment, the use of sensors is limited. Ultrasonic sensors have been widely used in the robot application for its simplicity and low cost. However, determining accurate distance and direction of the obstacle from ultrasonic sensors is quite difficult due to the expanding beam of the ultrasonic waves. The uncertainty about the distance and direction information limits the further application of ultrasonic sensors. In order to use ultrasonic sensors efficiently, a blackboard strategy for multiple ultrasonic sensors is developed in this paper. Based on the blackboard, information of the inner sensors of robot and information from ultrasonic sensors are integrated and fused at the data-level, character level and decision level. Finally, a simulation shows that the uncertainty of the distance and direction information has been eliminated to some degree and a more accurate workspace has been obtained.
Towards understanding innovation in construction

This is done through two separate parts. Part I looks at how corporate structure and inter-organizational networks are related to innovation in five European countries (Germany, Sweden, Denmark, France, the UK). Part II examines factors enabling and inhibiting the diffusion of sustainable technologies in the UK construction industry. Both parts are based on case studies. Part I draws on interviews with three to four contractors in each country; whereas Part II, among other sources, draws on the experiences from different sustainable energy projects within construction.
Compensatory head roll in the blowfly Calliphora during flight

Video records were made of the blowfly Calliphora erythrocephala L. mainly during tethered flight in a wind-tunnel, to study its movements about the longitudinal body axis (roll). During undisturbed flight, flies hold their head on average aligned with the body but may turn it about all three body axes. Pitch and yaw turns of the head are comparatively small (20°), whereas roll turns can be large (90°), and fast (1200° s-1). When passively rolled, flies produce compensatory head movements during walking or flight; at rest this reflex is turned off. Flies perceive a static misalignment relative to the vertical, as well as roll motion up to 10000° s-1. Within this range flies counteract an imposed roll with maximal gain at about 1000° s-1. Compensatory head movements are made with very low latency (down to ∆t ≈ 5ms), and with considerable speed (up to ω = 1000° s-1). Flies may ‘disregard’ an apparent deviation from their correct orientation, and may superimpose spontaneous head movements on those elicited by a stimulus. Compensatory head movements generally undercompensate the imposed misalignment. Simultaneously, however, flies modify their wing pitch and wingbeat amplitude to produce a compensatory roll torque. Since head and body roll act simultaneously and in the same direction, the overall speed and degree of head realignment, relative to external coordinates, increase considerably. This is certainly an advantage for flight in turbulent air. In still air, without need to correct an imposed misalignment, flies nevertheless produce spontaneous fluctuations of their flight torque, and head roll movements in the opposite direction. This is to be expected if flies intend to keep their eyes aligned with the coordinates of the environment while spontaneously performing banked turns. The limits of fly vision and the advantages of compensatory head movements for different visually guided behaviour are discussed. Compensatory head roll movements give flies greater manoeuvrability when cruising than the visual system would allow, without such a stabilizing reflex.
Establishing a sea bottom model by applying a multi-sensor acoustic remote sensing approach

Detailed information about the oceanic environment is essential for many applications in the field of marine geology, marine biology, coastal engineering, and marine operations. Especially, knowledge of the properties of the sediment body is often required. Acoustic remote sensing techniques have become highly attractive for classifying the sea bottom and for mapping the sediment properties, due to their high coverage capabilities and low costs compared to common sampling methods. In the last decades, a number of different acoustic devices and related techniques for analyzing their signals have evolved. Each sensor has its specific application due to limitations in the frequency range and resolution. In practice, often a single acoustic tool is chosen based on the current application, supported by other non-acoustic data where required. However, different acoustic remote sensing techniques can supplement each other, as shown in this thesis. Even more, a combination of complementary approaches can contribute to the proper understanding of sound propagation, which is essential when using sound for environmental classification purposes. This includes the knowledge of the relation between acoustics and sediment properties, the focus of this thesis. Providing a detailed three dimensional picture of the sea bottom sediments that allows for gaining maximum insight into this relation is aimed at.

Avaliação isocinética da fadiga em jogadores de futebol profissional

The aim of this study was to review the results of the relation between fatigue with the performance and incidence of injuries in soccer, as well as to check in the mentioned studies the fatigue test protocols in this sport. For this, were selected SCOPUS, PubMed, Journals Ovid, Web of Science e BMJ databases, and the keywords soccer and isokinetic, soccer and fatigue test, soccer and fatigue and isokinetic, soccer and injury. The studies included in this study were selected by the title containing the keywords and by reading the abstract, then checking if there was a relation between soccer, evaluation of fatigue in professional players, muscle imbalance and injury. The literature presents several protocols for the assessment of fatigue in professional soccer players. Although there is no consensus on what is the best protocol for evaluation, the fatigue index is an important parameter to be determined. Furthermore, the muscle ratios, especially the functional ratio, allow inferences about muscle balance and the propensity to develop related injuries to the knee joint in soccer players.
