Local density of electromagnetic states within a nanometric gap formed between two thin films supporting surface phonon polaritons
(AIP Publishing, 2010)
We present a detailed physical analysis of the near-field thermal radiation spectrum emitted by a silicon carbide (SiC) film when another nonemitting SiC layer is brought in close proximity. This is accomplished via the ...
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 ...
The traveling salesman problem with pickups, deliveries, and handling costs
(Informs, 2010-08)
This paper introduces a new variant of the one-to-many-to-one single vehicle pickup and delivery problems (SVPDP) that incorporates the handling cost incurred when rearranging the load at the customer locations. The ...
A branch-and-cut algorithm for solving the non-preemptive capacitated swapping problem
(Elsevier, 2010-08-06)
This paper models and solves a capacitated version of the Non-Preemptive Swapping Problem. This problem is defined on a complete digraph , at every vertex of which there may be one unit of supply of an item, one unit of ...
Optical subwavelength-scale displacement sensing with dynamically controllable characteristics
(The Optical Society, 2010)
Silicon photonic devices with embedded MEMS have significantly been studied. Characterization and operation of such devices in the nanometer-level is critical. A novel optical technique for subwavelength displacement ...
Investigation of stochastic pairs trading strategies under different volatility regimes
(Blackwell, 2010-09)
We investigate several market-neutral trading strategies and find empirical evidence that market-neutral equity trading outperforms in 2008, the first full year of the global financial meltdown. In our experiments we use ...
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 ...
