A REVIEW ON TASK ALLOCATION PERFORMANCE ISSUES IN CLOUD ENVIRONMENT

Cloud computing is an emerging paradigm in the computer industry where the computing is moved to a cloud of computers. It has become one of the buzz words of the industry. The core concept of cloud computing is, quite simply, that the vast computing resources that we need will reside somewhere out there in the cloud of computers and we’ll connect to them and use them as and when needed. Computing can be described as any activity of using and/or developing computer hardware and software. It includes everything that sits in the bottom layer, i.e. everything from raw compute power to storage capabilities. Cloud computing ties together all these entities and delivers them as a single integrated entity under its own sophisticated management. Load balancing is a mechanism that distributes the dynamic workload equally across over the nodes or virtual machines within the whole cloud server to avoid a state of conflict wherever some virtual machines are measured as heavily loaded whereas others nodes or hosts are measured as idle or doing very little work. It helps to realize a high client satisfaction and resource utilization magnitude relation, consequently increasing the performance and resource utility of the system. It additionally makes sure that each computing resource in the cloud server is distributed with efficiently and fairly among all the requests of the client. It additionally prevents bottlenecks of the system which can occur because of load imbalance.
Aeration of volatile organic compounds using gas dispersion impellers

A number of volatile organic compounds (VOCs) are found in the wastewater and some of these VOCs are very harmful to human health as well as environment. Although there are several methods which are being used for the removal of VOCs, air stripping process is the low energy usage, low preventive and maintenance cost and high efficiency process which can stripe VOCs from wastewater. The present study consists of aeration system for the removal of VOCs. Aeration of VOC is based on the mass transfer rate of VOCs from the liquid to gaseous phase. Principle of air stripping involves the mass transfer of volatile organic contaminant from water to air. The system can be easily upgraded to strip greater amount of VOCs with relatively small increase in capital cost. Aeration tanks strip volatile compounds by bubbling air into tank through which contaminated water flows. The present study shows aeration of a VOC by using advanced designed gas dispersing radial impeller that is, Rushton, CD-6 and BT-6 and the factors which affect the design of an aeration tank baffles and the impeller used for best possible result. This study also shows the removal of VOCs at different height of submergence. It also shows the effect of air supply on the removal of VOCs at different operating condition. A comparison of the result from experiment shows the emission rate of VOCs during aeration and is a function of mass transfer coefficient of air; it increases with increase of submergence of height, by supply of air, and increase in impeller speed. Best aeration result can be obtained at the 2/3rd height of the submergence of the total depth of water for impeller used. The study also shows that the gas dispersion BT-6 impeller has larger removal efficiency (up to 96%, with air supply at 4 h run) compare to Rushton and CD-6 impeller. Key words: Volatile organic compounds (VOCs), aeration, mass transfer coefficient, stripping, gas dispersion impellers, Rushton, CD-6, BT-6, gas liquid mass transfer.
Analysis of Bleeding Complications in Acute Coronary Syndrome: Comparison of Effect of Tirofiban in Diabetic and Non-Diabetic Patients

Background: Coronary artery disease (CAD) is the most prevalent manifestation of cardiovascular diseases and is associated with high mortality and morbidity. The clinical presentations of CAD include silent ischemia, stable angina pectoris, unstable angina, myocardial infarction (MI), heart failure, and sudden death. Objective: This study was designed to define the frequency of hemorrhagic complications and to identify clinical variables associated with increased risk of bleeding complications in diabetic versus non-diabetic patients presented with acute coronary syndrome whom received aspirin, clopidogrel and heparin only or in combination with GPIIb/IIIa receptors blockade (Tirofiban) and to detect any bleeding complications in all patients during the period of admission in the hospital. Patients and Methods: 150 patients with ACS were divided into two groups, 82 diabetic patients and 68 nondiabetic patients. 40 patients out of total sample received tirofiban. Assessment of in hospital TIMI bleeding, GRACE and CRUSADE risk scores was estimated for all of them. Results: We observed that, there is no statistically significant difference in TIMI bleeding in both heparin and tirofiban group in diabetic versus non-diabetic patients. Cardiac catheterization access site was the most frequent location of bleeding most likely secondary to the high rate of coronary angiography performed in the study. Tirofiban added to heparin did not increase the risk of bleeding at the vascular access site.Conclusion: There was no statistically significant increase in all TIMI bleeding, thrombocytopenia or blood transfusions with the combination of tirofiban with heparin in both diabetic and non-diabetic patients.
Trapped in Poor Places? An Assessment of the Residential Spatial Patterns of Housing Choice Voucher Holders in 2004 and 2008

ABSTRACT This study examines the residential spatial patterns of Housing Choice Voucher holders in Western New York in 2004 and 2008 (n = 4,600 and n = 4,759, respectively). It seeks to answer two questions: Has the concentration of voucher holders in impoverished and same race neighborhoods diminished overtime; and are voucher holders, particularly African Americans, relocating in patterns that would lead to reghettoization or the reconcentration of race and poverty? This type of residential pattern puts voucher holders at risk for resettling in neighborhoods that limit economic and social mobility. Data from the public housing agency contracted to distribute Housing Choice Vouchers were examined. Exploratory spatial analysis techniques were used to identify spatial outliers and to form a hypothesis on spatial patterns of relocation. Spatial clustering analyses were conducted to test the hypothesis on the reghettoization of African American voucher holders in recently relocated neighborhoods. Analyses indicate that African American voucher holders are moving out of impoverished, hypersegregated areas into historically White neighborhoods. A limited number of voucher holders are moving in clustered patterns, which lead to reghettoization. Future research is needed that highlights the role that housing assistance providers play in the residential location choices of low-income clients.
EXPLORING THE INPUT OF COMPETENCE ASSESSMENT TO GOAL-SETTING IN VARIOUS TYPES OF ORGANIZATIONS

The aim of the present research is to investigate the existing practices of linking competence assessment to organizational goal-setting in various organisations in Latvia. The importance of linking employee competences to goal-setting within organizations has been established in scientific literature. Nevertheless, there is evidence gathered in this interdisciplinary research that existing methods of competence assessment used by various organizations in Latvia do not translate well into organizational goal-setting. The research is based on information gathered from semi-structured interviews with representatives of managerial positions in private and public, including educational service organizations (26 in total). Additionally, publicly available development plans are analysed. Empirical data are analysed according to a conceptual framework of criteria impacting the goal-setting process. Three subsets of criteria are used that guided interview question formulation and interview data analysis: formulation of a goal; employee’s ability to reach the assigned goal; employee’s self-assessment on his/her ability to reach the assigned goal. Analysis of the results indicate that when setting goals and assessing employee competences in relation to those goals, management decisions are greatly guided by subjective approaches. Such identified approaches in observed private and public service organizations indicate common risks that are discussed in this research.
Use of miniature soil stress measuring cells under repeating loads

Different types of soil stress measuring cells have been successfully used in model tests under monotonic loading after following a strict calibration exercise to simulate field conditions. This paper explores the potential of one particular type of strain-gauged cell (type TML–PDA–200kPa) to determine the magnitudes of stresses generated at soil-structure interfaces and also within the soil medium for repeating load tests on models at 1 g. Difficulties associated with the use and calibration of these cells, including hysteresis, are discussed. In the present investigation, repeating load tests performed on dry sand prepared at different density states indicated that the cell response was strongly dependent on sand density, load amplitude, loading frequency and number of load cycles.
Estimated Prey Consumption by Harp seals (Phoca groenlandica), Hooded seals (Cystophora cristata), Grey seals (Halichoerus grypus) and Harbour seals (Phoca vitulina) in Atlantic Canada

Consumption of prey by harp (Phoca groenlandica), hooded (Cystophora cristata), grey (Halichoerus grypus), and harbour (Phoca vitulina) seals in Atlantic Canada was estimated for the period 1990–96 by synthesizing and integrating information on individual energy requirements, population size, distribution and diet composition. Total annual consumption by these four species increased from 3.1 million to 4.0 million tons over the seven-year period. Seventy-seven percent (by weight) of the total prey consumption consisted of fish, of which capelin and sand lance were the dominant species accounting for 49% (by weight) of the total fish consumed. The majority (74%) of total prey consumption occurred off southern Labrador and Newfoundland (Div. 2J and 3KL), followed by the northern Gulf of St Lawrence (Div. 4RS) (18%), and the eastern Scotian Shelf (Div. 4VsW) (4%). Harp seals were the most important predator, accounting for 82% of total consumption, followed by hooded seals (10% of total prey consumption), grey seals (7.8%), and harbour seals (0.2%). Regional differences existed in predation impacts of the four pinnipeds; harp seals were most important in Div. 2J and 3KL and in Div. 4RS, hooded seals were most important in Div. 2J and 3KL and Div. 3M (Flemish Cap), while grey seal predation predominated in the southern Gulf of St. Lawrence (Div. 4T) and on the Scotian Shelf (Div. 4VsW). Of the 3.1 million tons of fish consumed by the four species of seals in 1996, only about 20% accounted for commercial species such as Greenland halibut (7%), Atlantic cod (6%), redfish (4%), and Atlantic herring (3%). Most of the consumption of these commercial species consisted of juveniles.
The role of non-invasive brain stimulation in neurorehabilitation of post-stroke dysphagia.

Post stroke dysphagia has been related to an increased risk for pulmonary complications and higher rate of morbidity and mortality. A developing body of evidence has pointed to noninvasive brain stimulation techniques as efficient neurorehabilitation approaches in treatment of post-stroke dysphagia. Transcranial magnetic stimulation (TMS) depending on frequency and transcranial direct current stimulation (tDCS) depending on the duration and polarity of stimulation can activate or suppress activity in cortical regions. Enhancement of cortical excitability in the undamaged hemisphere has been related to the improvement of swallowing function in post stroke dysphagia. Developing data suggest that adjunct of cortical stimulation and following reorganization of the intact swallowing cortex augmented the speed of improvement of oropharyngeal dysphagia after a unilateral hemispheric stroke. This Review aims to evaluate the effects of the role of noninvasive brain stimulation techniques including TMS and tDCS as facilitators of recovery from post stroke dysphagia.
Globalization and Firm Refocusing

When a firm produces a single product, its best response to import competition is to reduce output and even shut down. However, many firms produce multiple products that are related to one another via various cost and demand complementarities. Thus, import competition directed at one product has implications for a firm’s entire product mix. Drawing upon insights from the concept of ‘core competency’ (e.g., Aghion and Tirole, 1995), I consider two ways in which import competition affects multi-product firms. (i) In response to rising core-product imports, the firm will protect the core by shifting resources from the periphery to the core. This will lead the firm to contract its peripheral products and expand its core products. (ii) In contrast, rising peripheral-product imports will lead to a conventional response i.e., to the firm shedding its peripheral products. Using Compustat data for more than 1,000 firms over the period 1984-1996, I find striking support for these implications. First, a rise in imports of core products leads to a contraction of periphery products and an expansion of core products as measured by sales, sales growth, and exit probabilities. Second, the weaker the complementarities that a peripheral product shares with the core (as measured by the extent of joint production, joint purchases of inputs, and joint sales to buyers), the more likely is the peripheral product to be divested in response to import competition. These facts point clearly to the need for distinguishing between single-product and multi-product firms when examining the impacts of import competition. (JEL classification: F1, F15, L23, M21)
Foundations of Financial Sector Mechanisms and Economic Growth in Emerging Economies: A Panel-Data Approach towards a Nexus

In this paper, we try to uncover the economic foundations of financial sector development and its impacts on accelerating economic growth in the given context of emerging economies. We theorize and empirically test a causally-motivated relationship among economic growth and related key financial sector variables pertinent to this problem. We accomplish this by analyzing a 20 year panel-data constructed for 30 countries falling within the categorization of an 'emerging economy'. We estimate the appropriate statistical models along with related diagnostic tests. Finally, we comment on the strengths and weaknesses of our approach and we try to explicate the economic rationale and justification for our formulation and the evidences that follow.
Grain Refinement of Freeform Fabricated Ti-6Al-4V Alloy Using Beam/Arc Modulation

Grain refinement can significantly improve the mechanical properties of freeform-fabricated Ti-6Al-4V alloy, promoting increased strength and enhanced isotropy compared with coarser grained material. Large beta-grains can lead to a segregated microstructure, in regard to both alpha-phase morphology and alpha-lath orientation. Beam modulation, which has been used in conventional fusion welding to promote grain refinement, is explored in this study for use in additive manufacturing processes including electron beam freeform fabrication (EBF(sup 3)) and gas-tungsten arc (GTA) deposition to alter solidification behavior and produce a refined microstructure. The dynamic molten pool size induced by beam modulation causes rapid heat flow variance and results in a more competitive grain growth environment, reducing grain size. Consequently, improved isotropy and strength can be achieved with relatively small adjustments to deposition parameters.
Study of the luminous blue variable star candidate G26.47+0.02 and its environment

Aims. The luminous blue variable (LBV) stars are peculiar very massive stars. The study of these stellar objects and their surroundings is important for understanding the evolution of massive stars and its effects on the interstellar medium. We study the LBV star candidate G26.47+0.02. Methods. Using several large-scale surveys in different frequencies we performed a multiwavelength study of G26.47+0.02 and its surroundings. Results. We found a molecular shell (seen in the 13CO J = 1–0 line) that partially surrounds the mid-infrared nebula of G26.47+0.02, which suggests an interaction between the strong stellar winds and the molecular gas. From the HI absorption and the molecular gas study we conclude that G26.47+0.02 is located at a distance of ∼4.8 kpc. The radio continuum analysis shows both thermal and non-thermal emission toward this LBV candidate, pointing to wind-wind collision shocks from a binary system. This hypothesis is supported by a search of near-IR sources and the Chandra X-ray analysis. Additional multiwavelength and long-term observations are needed to detect some possible variable behavior, and if that is found, to confirm the binary nature of the system.
Linking Knowledge Creation with Employee Engagement: A Conceptual Model

Employee engagement is increasingly important in this competitive society because organizational competitive advantage requires knowledge especially the tacit which resides in employees and this cannot be achieved unless employees are engaged in the process of knowledge creation. However, researches have rarely explored to bridge engaging employees with creating knowledge. This paper after reviewing relevant literatures on knowledge creation and employee engagement, emphasized the essential linkage between knowledge creation and employee engagement. It is expected to enhance theory that knowledge creation link to employee engagement. Hopefully, the proposed model could help organizations to understand how employee engagement can be a key approach to achieve competitive advantage through knowledge creation.
Torsion-rotational spectra within the vibrational ground state

Dimethyl ether (CH3OCH3) is one of the largest organic molecules detected in the interstellar medium. As an asymmetric top molecule with two methyl groups which undergo large amplitude motions and a dipole moment of μ = 1.3 D, it conveys a dense spectrum throughout the terahertz region and contributes to the spectral line confusion in astronomical observations at these frequencies. In this paper, we present rotational spectra of dimethyl ether in its ground vibrational states, which have been measured in the laboratory and analyzed covering frequencies up to 2.1 THz. The analysis is based on an effective Hamiltonian for a symmetric two-top rotor and includes experimental data published so far. Frequency predictions are presented up to 2.5 THz for astronomical applications with accuracies better than 1 MHz.
'Re-composing the Elephant': Bringing the Big Picture back into IS Research

Information Systems is a practice-based discipline. It experiences periodic debates about the rigour and relevance of its research. The tensions between pretensions to be a ‘real’ science (rigour) and the need to contribute to practice (relevance) are intensified at a time of low student enrolment, lack of a clear identity, and uncertainties about the viability of our discipline. This essay argues that decomposing phenomena into narrow topics of research to achieve rigour is damaging to our discipline if we fail to then ‘recompose’ or integrate these back into understanding, lessons and guidelines for application to real-world practices. This argument is illustrated through recent work on the motors that drive changes in technology appropriation. It highlights the importance of plurality of theories and methods in understanding complex real-world phenomena in order to achieve both rigour and relevance.
Systematic challenges in a refugee camp

Systemic therapists work in many different settings and face varied challenges. What I will try to outline here are some of my experiences in working in a large refugee camp in Africa and some of the challenges I face there. Although not many situations encountered there would be of direct relevance to therapists working in more traditional settings, nevertheless, I believe that many of the issues that I will address below can be related to most of the challenges we face, whatever our work setting may be. Moreover, I would argue that working in different settings may help us to sharpen and deepen our understanding of systemic principles which tend to become imprecise within the context of too familiar and predictable work settings.

NEUTRINO MASSES VIA A SEESAW WITH HEAVY MAJORANA AND DIRAC NEUTRINO MASS MATRICES FROM DISCRETE SUBGROUP

Neutrino mass matrix via a seesaw mechanism is constructed by assumming that the underlying symmetry of both heavy Majorana and Dirac neutrino mass matrices is the discrete subgroup �(27) symmetry of SU(3). Using the experimental data of neutrino oscillations, the neutrino mass matrix exhibits maximal �µ − �� mixing and has a specific prediction on the effective neutrino mass in neutrinoless double beta decay which can be tested in future experiment.
Managing Volatility Risk: An Application of Karhunen-Lo\`eve Decomposition and Filtered Historical Simulation

Implied volatilities form a well-known structure of smile or surface which accommodates the Bachelier model and observed market prices of interest rate options. For the swaptions that we study, three parameters are taken into account for indexing the implied volatilities and form a "volatility cube": strike (or moneyness), time to maturity of the option contract, duration of the underlying swap contract. It should be noted that the implied volatility structure changes across time, which makes it important to study its dynamics in order to well manage the volatility risk. As volatilities are correlated across the cube, it is preferable to decompose the dynamics on orthogonal principal components, which is the idea of Karhunen-Lo\`eve decomposition that we have adopted in the article. The projections on principal components are investigated by Filtered Historical Simulation in order to predict the Value at Risk (VaR), which is then examined by standard tests and non-arbitrage condition to ensure its appropriateness.
Effects Of Cohabiting Law And Alimony Rights Over Fertility In The Brazilian Northeast Region

One of the aspects of main importance for the determination of fertility is the insurance that marriage creates over a possible dissolution of the relationship. In this article, we present evidence that a greater level of insurance leads to a greater fertility. By analyzing the natural experiment given by the approval of the Cohabiting Law in December of 1994, we identify an increase on the intentions of pregnancy for poor women directly affected by the Law. This increase is accompanied from a reduction on the probability that cohabiting women make a sterilization surgery. Our results are valid under many robustness checks.
