Performance analysis of cooperative diversity networks with imperfect channel estimation
(IEEE, 2010)In this paper, we investigate the effect of channel estimation error on the error rate performance of a multi-relay system with amplify-and-forward relaying. We consider orthogonal relaying and study both conventional ... -
Redundancy estimation and adaptive density control inwireless sensor networks
(Old City Publishing, 2010)While dense random deployment satisfies coverage and sensing requirements, constructing dense networks of sensor nodes poses the problems of obtaining node location information.We provide an analytical framework for ... -
Diffusion-based approach to deploying wireless sensor networks
(Inderscience, 2010)An important objective of Wireless Sensor Networks (WSNs) is to reliably sense data about the environment in which they are deployed. Reliability in WSNs has been widely studied in terms of providing reliable routing ... -
Connection characteristics of silicon nanowire waveguides and fabrication of physical contact switches
(IEEE, 2010)Optical characteristics of silicon nanowire waveguide connections are studied both theoretically and experimentally. Effects of geometrical sizes and positional alignments on optical performance are investigated. Results ... -
Integrated airline schedule design and fleet assignment: polyhedral analysis and benders’ decomposition approach
(Informs, 2010-01)The main airline operations consist of schedule planning, fleet assignment, aircraft routing, and crew scheduling. To improve profitability, we present in this paper an integrated fleet assignment model with schedule ... -
Polarization imaging of multiply-scattered radiation based on integral-vector Monte Carlo method
(Elsevier, 2010-01)A new integral-vector Monte Carlo method (IVMCM) is developed to analyze the transfer of polarized radiation in 3D multiple scattering particle-laden media. The method is based on a “successive order of scattering series” ... -
A unified Monte Carlo treatment of the transport of electromagnetic energy, electrons, and phonons in absorbing and scattering media
(Elsevier, 2010-02)The scalar Boltzmann transport equation (BTE) is often applicable to radiative energy transfer, electron–beam propagation, as well as thermal conduction by electrons and phonons provided that the characteristic length of ... -
Axial charges of octet baryons in two-flavor lattice QCD
(Elsevier, 2010-03-15)We evaluate the strangeness-conserving NN, ΣΣ, ΞΞ, ΛΣ and the strangeness-changing ΛN, ΣN, ΛΞ, ΣΞ axial charges in lattice QCD with two flavors of dynamical quarks and extend our previous work on pseudoscalar-meson–octet-baryon ... -
Discrete time/cost trade-off problem: a decomposition-based solutionalgorithm for the budget version
(Elsevier, 2010-04)This paper investigates the budget variant of the discrete time/cost trade-off problem (DTCTP). This multi-mode project scheduling problem requires assigning modes to the activities of a project so that the total completion ... -
Design, operation, and motion characteristics of a precise piezoelectric linear motor
(Elsevier, 2010-04)This paper presents the design, operation, and motion characteristics of a precise piezoelectric motor for linear translation. The motor is compact, thermally stable, ultra-high vacuum compatible, and suitable for applications ... -
Iterative near maximum-likelihood sequence detection for MIMO optical wireless systems
(IEEE, 2010-04)A major performance-limiting factor in terrestrial optical wireless (OW) systems is turbulence-induced fading. Exploiting the additional degrees of freedom in the spatial dimension, multiple laser transmitters combined ... -
Pseudoscalar-meson octet-baryon coupling constants from two-flavor lattice QCD
(Elsevier, 2010-04-01)We evaluate the pseudoscalar-meson octet-baryon coupling constants and the corresponding axial charges in eight channels (πNN, πΣΣ, πΛΣ, KΛN, KΣN, πΞΞ, KΛΞ and KΣΞ) in lattice QCD with two flavors of dynamical quarks. The ... -
Tailoring silica nanotribology for CMP slurry optimization: Ca2+ cation competition in C12TAB mediated lubrication
(ACS, 2010-04-12)Self-assembled surfactant structures at the solid/liquid interface have been shown to act as nanoparticulate dispersants and are capable of providing a highly effective, self-healing boundary lubrication layer in aqueous ... -
Adaptive density control in heterogeneous wireless sensor networks with and without power management
(IEEE, 2010-04-30)The authors study the design of heterogeneous two-tier wireless sensor networks (WSNs), where one tier of nodes is more robust and computationally intensive than the other tier. The authors find the ratios of densities of ... -
ZMP-based online jumping pattern generation for a one-legged robot
(IEEE, 2010-05-01)This paper is aimed at presenting a method to generate online jumping patterns, which can be applied to one legged jumping robots and optionally to humanoid robots. Our proposed method is based on ensuring the overall ... -
The attractive traveling salesman problem
(Elsevier, 2010-05-16)In the Attractive Traveling Salesman Problem the vertex set is partitioned into facility vertices and customer vertices. A maximum profit tour must be constructed on a subset of the facility vertices. Profit is computed ... -
A retrospective view on‘‘3-dimensional radiation in absorbing, emitting and scattering media using discrete-ordinates approximation’’by J.S.Truelove
(Elsevier, 2010-06)Discrete-ordinates (DO) approximations to the radiative transfer equation in three- dimensional enclosures have extensively been used during the last three decades. The 1988 paper by Truelove [1] is one of the pioneering ... -
On ‘‘Radiative transfer in three-dimensional rectangular enclosures containing inhomogeneous,anisotropically scattering media’’
(Elsevier, 2010-07)Our 1985 paper (JQSRT 1985; 33: 533–549) reported the result of the research we conducted back then to better understand heat transfer processes in large-scale combustion chambers, especially in pulverized coal-fired ... -
Calibrating artificial neural networks by global optimization
(2010-07)An artificial neural network (ANN) is a computational model − implemented as a computer program − that is aimed at emulating the key features and operations of biological neural networks. ANNs are extensively used to model ... -
