Dynamics of Random Early Detection
- In Proceedings of ACM SIGCOMM
, 1997
"... In this paper we evaluate the effectiveness of Random Early Detection (RED) over traffic types categorized as nonadaptive, fragile and robust, according to their responses to congestion. We point out that RED allows unfair bandwidth sharing when a mixture of the three traffic types shares a link Thi ..."

This urlfairness is caused by the fact that at any given time RED imposes the same loss rate on all jlows, regardless of their bandwidths. We propose Fair Random Early Drop (FRED), a modified version of RED. FRED uses per-active-jlow accounting to impose 011 each flow a loss rate that depends on the flow’s buffer
Health-Related Quality of Life in Persons with Memory Loss and their
, 2012
"... Background/Purpose: The burden of memory loss can affect health-related quality of life (HRQoL) for those with memory loss as well as for their informal caregivers. This study describes physical and mental HRQoL for both caregivers and their care recipients ’ and examines associations among physical ..."

Noise-induced spatial dynamics in the presence of memory loss
, 2007
"... Abstract We study the spatial dynamics of noise-induced waves in two-dimensional excitable media in dependence on the duration of the artificially imposed refractory time that is introduced to each constitutive system unit after an excitation. Due to the introduction of refractory times, a randomly ..."

. We show that even in the presence of such memory loss, self-organization of excitatory events leads to noise-induced spatial periodicity in the media. We present a simple analytical treatment of a two-unit system to capture and explain the essence of the observed phenomenon. Since refractory times
Memory Loss and Response Bias in Senescence1
"... Recognition memory was studied in young and elderly women by assessing memory strength and response bias using Signal Detection Theory methodology. Young women (mean age 21 years; n = 8) had better recognition memory (d ' and d'e) than did elderly women (mean age 71 years; n = 16) but the ..."

research, evaluation of memory in terms of correct and incorrect recognitions can lead to erroneous interpretations, due to uncontrolled bias effects. Age does adversely influence recognition memory strength suggesting that ac-quisition and/or storage processes are not invariant with age. MEMORY loss
Memory loss for time-dependent dynamical systems
- Math. Res. Lett
"... Abstract. This paper discusses the evolution of probability distributions for certain time-dependent dynamical systems. Exponential loss of memory is proved for expanding maps and for one-dimensional piecewise expanding maps with slowly varying parameters. 1. ..."

A Guttman Scale to Assess Memory Loss Among the Elderly
"... A modification of the Mental Status Questionnaire using questions requiring the recall of basic memory is described. After interviewing 254 elderly people, the responses to six questions were found to meet the criteria for Guttman scaling, and each respondent was assigned a score which characterized ..."

characterized the extent of his memory loss. After a 14-month-follow-up, it was found that a statistically significant proportion of the low scores, i.e., those with more memory loss, had died. The technique described is useful for comparing respondents ' extent of memory loss both to assess high risk
Activity Theory Applied to the Corporate Memory Loss Problem
, 2000
"... In 1989 a work procedure hierarchy was developed as a model for a database to store corporate memory in the form of decomposed and linked work procedures. This paper describes the development of this work procedure hierarchy over the last ten years and the significant contribution of Activity Theory ..."

years now the loss of corporate memory has been a significant problem for both public and private organizations. Many attempts have been made over the years to solve this problem. A large government utility attempted to solve this problem with an information system based on a work procedure hierarchy
Should We Worry About Memory Loss?
"... In recent years the High Performance Computing (HPC) industry has benefited from the development of higher density multi-core processors. With recent chips capable of executing up to 32 tasks in parallel, this rate of growth also shows no sign of slowing. Alongside the development of denser micro-pr ..."
Abstract
- Add to MetaCart
-processors has been the considerably more modest rate of improvement in random access memory (RAM) capacities. The effect has been that the available memory-percore has reduced and current projections suggest that this is still set to reduce further. In this paper we present three studies into the use
