Paired Pulse Basis Functions and Triangular Patch Modeling for the Method of Moments Calculation of Electromagnetic Scattering from Three-Dimensional, Arbitrarily-Shaped Bodies
(2009-02-23)
Due to an increasing emphasis on fabrication with composite materials, it is important
to be able to model accurately the electromagnetic properties of composite structures. In
this work, we demonstrate a new pair of ...
Online In-Situ Estimation of Network Parameters Under Intermittent Excitation Conditions
(2009-02-23)
Online in-situ estimation of network parameters is potential tool to evaluate electrical network and conductor health. The integration of the physics-based models with stochastic models can provide important diagnostic ...
Breakdown studies of helium and nitrogen in partial vacuum subject to non-uniform, unipolar fields in the 20-220 kHz range
(2009-02-23)
Partial discharges and corona are considered as unwanted processes in electrical power systems since they are constant source of power loss and electrical noise (EMI). These effects can further develop into a major problem ...
Soft Error Rate Determination For Nanometer CMOS VLSI Circuits
(2009-02-23)
Nanometer CMOS VLSI circuits are highly sensitive to soft errors due to envi-
ronmental causes such as cosmic radiation and high-energy particles. These errors are
random and not related to permanent hardware faults. ...
Built-In Self-Test for Input/Output Tiles in Field Programmable Gate Arrays
(2008-09-09)
Very large scale integration (VLSI) circuits use input/output (I/O) cells to both send and receive signals from external resources. Field Programmable Gate Arrays (FPGAs) and System-on-Chips (SoCs) with FPGA cores offer ...
Node Placement, Routing and Localization Algorithms for Heterogeneous Wireless Sensor Networks
(2008-09-09)
Wireless sensor network is a very promising technology for many
military and civilian applications. The network usually consists
large number of nodes and many existing network techonlogies can
not be used directly in ...
