Experimental and numerical investigation of the effect of phase change materials on clothing during periodic ventilation

Ghali K.; Ghaddar N.; Harathani J.; Jones B. (PRINCETONPO BOX 625, PRINCETON, NJ 08540 USA, 2004)

A numerical and experimental investigation is conducted of periodic ventilation processes in fabric containing microcapsules of phase change materials (PCM). When PCMS are added to textiles, they release heat as the liquid ...
SmartSLAM: Localization and mapping across multi-environments

Asmar D.C.; Zelek J.S.; Abdallah S.M. (, 2004)

In the absence of absolute localization tools such as GPS, a robot can still successfully navigate by conducting Simultaneous Localization and Mapping (SLAM). All SLAM algorithms to date can only be applied in one environment ...
Pressure-based algorithms for multifluid flow at all speeds - Part II: Geometric conservation formulation

Moukalled F.; Darwish M. (PHILADELPHIA325 CHESTNUT ST, SUITE 800, PHILADELPHIA, PA 19106 USA, 2004)

This work is concerned with the implementation and testing, within a structured collocated finite-volume framework, of seven segregated algorithms for the prediction of multiphase flow at all speeds. These algorithms belong ...
A comparative assessment within a multigrid environment of segregated pressure-based algorithms for fluid flow at all speeds

Darwish M.; Asmar D.; Moukalled F. (, 2004)

This article deals with the evaluation of six segregated high-resolution pressure-based algorithms, which extend the SIMPLE, SIMPLEC, PISO, SIMPLEX, SIMPLEST, and PRIME algorithms, originally developed for incompressible ...
Inertia effects on the modulated air layer heat and moisture transport from clothing with open aperture

Ghaddar N.; Ghali K.; Harathani J. (, 2004)

A two-dimensional model is developed of the modulated internal airflow in the gap between clothing and skin surface due to walking and in presence of clothing end apertures. The normal airflow renewing the air layer through ...
Heat and transport through the micro-climate air annulus of the clothing-skin system under periodic motion

Ghaddar N.; Ghali K.; Jaroudi E. (NEW YORKTHREE PARK AVENUE, NEW YORK, NY 10016-5990 USA, 2005)

A dynamic thermal model is developed using the 2-D cylinder model of Ghaddar et al [1] of ventilated fabric-skin system where a microclimate air annulus separates an outer cylindrical fabric boundary and an inner human ...
Novel MEMS L-switching matrix optical cross-connect architecture: Design and analysis - Optimal and staircase-switching algorithms

Yeow J.T.W.; Abdallah S.S. (PISCATAWAY445 HOES LANE, PISCATAWAY, NJ 08855 USA, 2005)

Free-space optical cross connect (OXC) for optical switching has shown promise in replacing traditional electronic switching fabrics. Micromachined optical switches offer superior performance in terms of bit rate and ...
Optimum synthesis of mechanisms using tabu-gradient search algorithm

Smaili A.A.; Diab N.A.; Atallah N.A. (, 2005)

A tabu-gradient search is herein presented for optimum synthesis of planar mechanisms. The solution generated by a recency-based, short term memory tabu search is used to start a gradient search to drive the solution ever ...
Adaptive fuzzy logic control of a flexible four-bar mechanism with a smart coupler link

Smaili A.; Mrad F.; Maamoun H. (, 2005)
