A self–routing permutation network is a connector which can set its own switches to realize any one-to-one mapping of its inputs onto its outputs. Many permutation networks have been reported in the literature, but none with self–routing property, except crossbars and cellular permutation arrays which have excessive cost. This paper describes a self–routing permutation network which has O(log n...

The new telecommunication networks scenario is characterised by a very rapid increase of the volume of traffic, and also very variable and unpredictable traffic demands. In this context, all-optical packet switching is emerging as the most promising technology for covering such new requirements. In this paper, we deal with the performance analysis of an optical packet switch with a feedback del...

People are more sensitive at detecting asynchrony between a self-generated movement and visual feedback concerning that movement when the movement is viewed from a first-person perspective. We call this the 'self-advantage' and interpret it as an objective measure of self. Here we ask if disruption of the vestibular system in healthy individuals affects the self-advantage. Participants performe...

One of the major causes of morbidity and mortality in breast cancer patients is delay in seeking help. Leventhal's self-regulation model provides an appropriate framework to assess delay in seeking help. The aim of this study was to investigate the relationship between "illness perception" and "help seeking delay" in breast cancer patients based on Leventhal's self-regulation model. In this cor...

conclusions a significant association was found between ages of women with their delays in consultation. delay is still prevalent amongst women with breast cancer. it seems necessary to design educating programs for women in both clinical and community settings, about breast cancer and early detection practices. results the mean age of women was 46.99 years. 38.4% of women were ≤ 40 years. 61% ...

Variations of the self-imposed delay-of-gratification situation in preschool were compared to determine when individual differences in this situation may predict aspects of cognitive and self-regulatory competence and coping in adolescence. Preschool children from a university community participated in experiments that varied features of the self-imposed delay situation. Experimental analyses o...

A semi-empirical mathematical model for predicting the physical part of ignition delay period in the combustion of diesel engines with swirl is developed. This model is based on a single droplet evaporation model. The governing equations, namely, equations of droplet motion, heat and mass transfer were solved simultaneously using a Runge-Kutta step by step method. The computation was executed u...

A short-term longitudinal study (N = 162 undergraduate students) replicates and extends previous findings on the relationship between self-reported procrastination and behavioral measures of procrastination (i.e., a comparison between actual and planned study time), and assesses their relation with affective well-being. All variables were measured 16 times over the course of 8 weeks. State meas...
