aging is a crucial period in human life and it is a social necessity to pay attention to the issues and needs of this stage of life. the aim of the current study was to study the effect of body mass index (bmi) on reaction time and response time of the active and inactive elderly. the research method was causal-comparative and its statistical population consisted of the elderly from mahabad cit...

This study addresses the relationship between item response time and item accuracy (i.e., the response time accuracy correlation, RTAC) in figural matrices tests. The dual processing account of response time effects predicts negative RTACs in tasks that allow for relatively automatic processing and positive RTACs in tasks that require controlled processing. Contrary to these predictions, severa...

Response time is the time an agent needs to make a decision. One fundamental finding in psychology and neuroscience is that, in a binary choice, there is a monotonic relationship between the response time and the difference between the utilities of the two options. We consider situations in which utilities are not observed, but rather inferred from revealed preferences: meaning they are inferre...

Schedulability analysis of xed priority preemptive scheduled systems can be performed by calculating the worst-case response-time of the involved processes. The system is deemed schedulable if the calculated response-time for each process is less than the corresponding deadline. It is desirable that the employed Response-Time Analysis (RTA) can be eeciently performed. This is particularly impor...

(ABSTRACT) It is critical to understand WWW latency in order to design better HTTP protocols. In this study we characterize Web response time and examine the effects of proxy caching, network bandwidth, traffic load, persistent connections for a page, and periodicity. Based on studies with four workloads, we show that at least a quarter of the total elapsed time is spent on establishing TCP con...

This paper presents a work-in-progress on the response time variability problem. This problem occurs whenever events, jobs, clients or products need to be sequenced so as to minimize the variability of time they wait for their next turn in obtaining the necessary resources. The problem has numerous real-life applications, which will be briefly reviewed. The problem has distinctive number theore...

A new experiment measuring the dynamical response of the Internet population to a “pointlike” perturbation has been performed. The nature of the perturbation was that of an announcement, specifically a web-interview on stock market crashes, which contained the URL to the author’s articles on the subject. It was established that the download rate obeys the relation ≈ 1/t in qualitative agreement...
