The past decade have seen the rise of data-intensive scalable computing (DISC) systems, such as Hadoop, and the consequent demand for scheduling policies to manage their resources, so that they can provide quick response times as well as fairness. Schedulers for DISC systems are usually focused on the fairness, without optimizing the response times. The best practices to overcome this problem i...
Historically, job analysis has played a fundamental role for developing and validating licensure and certification examinations. Still, research on what constitutes reliable and valid job analysis data is lacking. This paper illustrates several ways to examine the reliability and validity of job analysis survey results. Generalizability theory and the many-facets Rasch model are applied to inve...
A network of workstations (NOWs) may be employed for high performance computing where execution time of a target job is to be minimized. Job arrival rate and size are “random” on a NOWs. In such an environment, partitioning (load balancing) a target job based on only the first order moments (means) of system parameters is not optimal. In this paper, it is proposed to consider the second order m...
Grid computing is a high performance computing environment to solve larger scale computational applications. Grid computing contains resource management, job scheduling, security problems, information management and so on. Job scheduling is a fundamental and important issue in achieving high performance in grid computing systems. However, it is a big challenge to design an efficient scheduler a...
It is important to identify scalability constraints in existing job scheduling software as they are applied to next generation parallel systems. In this paper, we analyze the scalability of job scheduling and job dispatching functions in the IBM LoadLeveler job scheduler. To enable this scalability study, we propose and implement a new virtualization method to deploy different size LoadLeveler ...
In optics the nonlinear Schrödinger equation (NLSE) which modelizes light-wave propagation in an optical fibre is the most widely solved by the Symmetric Split-Step method. The practical efficiency of the Symmetric Split-Step method is highly dependent on the computational grid points distribution along the fiber and therefore an efficient adaptive step-size control strategy is mandatory. A lot...
مدل روزنه های موازی موج دار (corrugated oarallel bundle model) برای تعریف اثر ساختمان روزنه ها در نفوذ-واکنش (diffusion and reaction) در کاتالیستهای متخلخل بکار می رود. در مدل روزنه های موج دار، از یک دسته روزنه های اصلی (pore) استفاده شده است . هر یک از این روزنه های اصلی دارای یکسری عناصر روزنه می باشد که هر عنصر دارای یک شعاع تعیین شده به صورت اتفاقی از یک توزیع اندازه روزنه ها (pore size di...
Background: Job satisfaction represents one of the most complex areas facing today’s managers when it comes to managing their employees. The low job satisfaction among nurses results negative outcome that affect both quality and cost of patient care. Dissatisfaction not only gives poor quality, but also less efficient care. Objective: To assess the level of job satisfaction and associated facto...
BACKGROUND Emotional intelligence is the potential to feel, use, communicate, recognize, remember, describe, identify, learn from, manage, understand and explain emotions. Service quality also can be defined as the post-consumption assessment of the services by consumers that are determined by many variables. OBJECTIVES This study was aimed to determine the nurses' emotional intelligence impa...
