In clinical settings, traditional stroke rehabilitation evaluation methods are subjectively scored by occupational therapists, and the assessment results vary individually. To address this issue, this study aims to develop a stroke rehabilitation assessment system by using inertial measurement units. The inertial signals from the upper extremities were acquired, from which three quantitative in...

We consider the dimensioning problem for Internet access links carrying TCP traffic with two priority classes. To this end, we study the behaviour of TCP at the flow level described by a multiple-server Processor Sharing (PS) queueing model with two customer classes, where the customers represent flows generated by downloading Internet objects; the sojourn times represent the object transfer ti...

research centers are among the most important institutes in a scientific society. using the altavista search engine and webometric methods, this research tries to find the performance and impact of the top research centers of the islamic world countries. the results reveal that from 57 countries, 40 of them did not have any research centers scored in webometric ranking and the rest of them had ...

The main aim of the study was to examine the relationship between youth athletes ́ perception of antisocial behavior and motivational climate as well as their opinion regarding antisocial behavior of their significant others. The participants were 1,897 young male and female athletes, ranging in age from 11 to 16 years, who played in basketball, handball, football, or volleyball teams. The resul...

With the number increment of mobile computing equipment, the invalidation of equipment and broadcasting information because of wireless bandwidth, communication quality and too long scheduling queue that badly influence the system computing performance. Mobile cache is a good technology to solute this difficult problem. Considering the priority problem of broadcasting queue generated by data in...

Priority queues are an important algorithmic component and are ubiquitous in systems and software. With the rapid deployment of parallel platforms, concurrent versions of priority queues are becoming increasingly important. In this paper, we present a novel concurrent lock-free linearizable algorithm for priority queues that scales significantly better than all known (lock-based or lock-free) p...

This report summarizes the research conducted at The University of Texas at Austin on the performance analysis of priority systems for containers. The performance analysis focused on a selected group of possible priority systems that differ in the extent in which service by priority is implemented. The systems analyzed are: (a) base case, i.e., no service differentiation; (b) "hot hatch program...

Abstract Priority queueing models have been commonly used in telecommunication systems. The development of analytically tractable models to determine their performance is vitally important. The discrete time batch Markovian arrival process (DBMAP ) has been widely used to model the source behavior of data traffic, while phase-type (PH) distribution has been extensively applied to model the serv...

Operating systems which implement a dynamic priority mechanism are very common. Nevertheless, it is very di cult to develop an accurate analytical model to evaluate their performance, mainly due to the different forms of dependency between the various constituent parts. In this paper, we introduce a black box modeling approach which allows us to identify and decompose the di erent functions of ...

In this brief, we introduce a priority encoder that uses a novel priority lookahead (PL) scheme to reduce delays associated with priority propagation. Two priority encoder approaches are presented, one without and the other with a PL scheme. For an -bit encoder, the circuit with the PL scheme requires about 0.1 more transistors than the circuit without the scheme. However, a 32-bit very large s...
