abstract— data grids are an important branch of gird computing which provide mechanisms for the management of large volumes of distributed data. energy efficiency has recently emerged as a hot topic in large distributed systems. the development of computing systems is traditionally focused on performance improvements driven by the demand of client's applications in scientific and business ...

with the rapid emergence of 3d applications and virtual environments in computer systems; the need for a new type of interaction device arises. this is because the traditional devices such as mouse, keyboard, and joystick become inefficient and cumbersome within these virtual environments. in other words, evolution of user interfaces shapes the change in the human-computer interaction (hci). in...

Fixture design is crucial part of manufacturing process. Fixture design is a critical design activity process, in which automation plays an integral role in linking computer-aided design (CAD) and computer-aided manufacturing (CAD). This paper presents a literature review in computer aided fixture design (CAFD) in terms of automation and optimization techniques over the past decades. First, the...

introduction: nowadays, the widespread distribution of hospital information systems (his) in healthcare institutions requires professional evaluation to assess the practical usefulness of these applications. nursing staff are the largest group of staff in a hospital and play an important role in the adoption and evaluation of hiss. methods: this was a descriptive, analytic, cross-sectional stud...

this paper presents a discrete-time single-server finite buffer n threshold policy queue with renewal input and discretemarkovian service process. the server terminates service whenever the system becomes empty, and recommencesservice as soon as the number of waiting customers in the queue is n. we obtain the system-length distributionsat pre-arrival and arbitrary epochs using the supplementary...

in many active noise control (anc) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. this paperproposes a new feedback anc system. here we modified both the fxlms and thevss-lms algorithms to raised noise attenuation and modelling accuracy for theoverall system. the proposed algorithm stops injection of the white noise at theoptimum...
