ATM networks being a connection-oriented technology are providing service for real-time communication. Before two hosts can communicate, a connection has to be established between them. After a connection is established, messages are divided into fixed size packets called cells and are being sent from a source host to a destination host. Real-time communication service requires the underlying n...

Recently, a new type of Design-for-Delay-Testability (DfDT) structure and associated Built-In Self-Test architecture for detecting delay faults in digital highperformance circuits has been proposed. It circumvents the requirement of an expensive high-speed tester. In this paper, the ability of the proposed structure to function correctly in an environment with processand application-induced var...

The analysis of Metacognitive skills is a key element to guide the learning process. Current research has shown the initiation of these skills from an early age. The present study had two aims: (1) to validate a Scale Measuring Precursor Metacognitive Skills (SMPMS) in children with diverse disabilities, and (2) to study possible significant different between different disabilities in precursor...

2008 iv Delay discounting—a behavioral measure of impulsivity defined as a tendency to prefer a small, immediate reward over a larger reward delayed in time—has been extensively linked with tobacco smoking. However, the causal direction of this relationship remains unclear. One possibility is that delay discounting may be a marker for an underlying vulnerability to nicotine reinforcement—a poss...

Background: Self-medication can lead to the latency of the real severity of disease, delay in diagnosis, a complication of treatment, threatening side effects, and unexpected intoxication. The present research aimed to explore the prevalence of self-medication and its factors among students affiliated to Bandar Abbas universities in 2016. Materials and Methods: This Descriptive Analytic study w...

Individuals with anorexia nervosa (AN) are often characterized as possessing excessive self-control and are unusual in their ability to reduce or avoid the consumption of palatable foods. This behavior promotes potentially life-threatening weight loss and suggests disturbances in reward processing. We studied whether individuals with AN showed evidence of increased self-control by examining the...

The ability of children to delay gratification is correlated with a range of positive outcomes in adulthood, showing the potential impact of helping young children increase their competence in this area. This study investigated the influence of symbolic models on the self-control of 3-year old children. Eighty-three children were randomly assigned to one of three modelling conditions: personal ...

This article proposes the XGOP-B deterministic traffic model for MPEG video services requiring strict bounds on the quality of service provided by the network. The XGOP-B model takes advantage of two characteristics of MPEG video traffic by performing a two-level analysis of such sources. In our scheme, the traffic parameters are directly obtained by a single-input single-output parameter extra...

Using a delay adaptation learning rule, we model the activity-dependent development of directionally selective cells in the primary visual cortex. Based on input stimuli, a learning rule shifts delays to create synchronous arrival of spikes at cortical cells. As a result, delays become tuned creating a smooth cortical map of direction selectivity. This result demonstrates how delay adaption can...

In this paper we exploit a model of a single TCP source introduced in [1] to show the dependence of the scaling properties of the TCP throughput on the correlation structure of the Round Trip Times (RTTs) and of the packet losses. The source works according to the most common TCP mechanisms, i.e. slow-start, congestion avoidance and exponential back-off retransmission timer. The innovation of t...
