Grounded in the Experiential Learning Theory and expertise research, this study examines the processes of experience-based learning, i.e., acquisition of skills and knowledge from direct experience, at different career stages of different types of IT professionals. A qualitative research method was used to compile a series of case studies on the basis of theoretical replication to answer this r...

Multiprocessor systems make it possible to reduce program execution time by using parallel processing. We present an architecture that implements triple modular redundancy (TMR) in FTAG (Fault Tolerant Attribute Grammar): a functional and attribute based model[2]. A replication scheme is developed for this architecture where three instances of a replicated job called replica are active at di er...

As grow as the data-intensive applications in cloud computing day after day, data popularity in this environment becomes critical and important. Hence to improve data availability and efficient accesses to popular data, replication algorithms are now widely used in distributed systems. However, most of them only replicate the static number of replicas on some requested chosen sites and it is ob...

Research Study: Registered Nurse Empowerment and Retention Correlations Student: Michele Etchison, RN, BSN, CNOR Degree: Masters of Science College: College of Applied Sciences and Technology Date: December, 2012 Many studies that have been conducted regarding job satisfaction and nurse retention, yet there is a lack of information about empowerment and how empowerment affects nurse retention. ...

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...

The remit of the European DataGrid (EDG) [2] project was to develop an infrastructure that could support the intensive computational and data handling needs of widely distributed scientific communities. An important part of managing the data present in such a Grid is file replication placing copies of files at different sites in order to reduce data access times, hence shortening job running ti...

ABSTRACT Motivated by distributed schedulers that combine the power-ofd-choices with late binding and systems that use replication with cancellation-on-start, we study the performance of the LL(d) policy which assigns a job to a server that currently has the least workload among d randomly selected servers in large-scale homogeneous clusters. We consider general service time distributions and p...

This paper studies parallel processing as a device for increasing fault tolerance. In the first of two basic models, a single job with a given running time is to be run on a finite set of processors; each processor is subject to failure but only while running a job. If a job is running on only one processor, and that processor fails, then the job must be restarted on another processor, assuming...

Large-scale Non-Uniform Memory Access (NUMA) multiprocessors are gaining increased attention due to their potential for achieving high performance through the replication of relatively simple components. Because of the complexity of such systems, scheduling algorithms for parallel applications are crucial in realizing the performance potential of these systems. In particular, scheduling methods...
