A computational framework of kinematic accuracy reliability analysis for industrial robots
(2020)A new computational method to evaluate comprehensively the positional accuracy reliability for single coordinate, single point, multipoint and trajectory accuracy of industrial robots is proposed using the sparse grid ... -
A design flow for the precise identification of the worst-case voltage drop in power grid analyses
(2008)Modern IC designs contain hundreds of millions of transistors and new implementations of multi core chips take place in commercial products. Identifying worst-case voltage drop conditions in every hierarchical module ... -
An efficient implementation on a low cost FPGA for photon detection in nuclear imaging
(2010)The aim of this study is to propose and evaluate a simple, open source, data acquisition (DAQ) tool, which provides accurate results for nuclear imaging applications. For this purpose a Xilinx Spartan3E Starter Kit, which ... -
Joint multiuser downlink beamforming and admission control: A semidefinite relaxation approach
(2007)Multiuser downlink beamforming under quality of service (QoS) constraints has attracted considerable interest in recent years, because it is particularly appealing from a network operator's perspective (e.g., UMTS, 802.16e). ... -
Pitch and flight path control with simultaneous forward gust rejection
(1999)The problem of rejecting atmospheric disturbances with simultaneous input-output decoupling of the pitch angle and the flight path angle of an aircraft, is studied. The problem is proven to be solvable for almost all flight ... -
Robust discretization algorithms for the numerical intergration of nonlinear PDEs with application to a generalized capacitor
(1998)Numerical integration of nonlinear (NL) partial differential equations (PDEs) is studied via approximating the original continuous-domain physical system by a discrete multidimensional (MD) and passive system, using ... -
Simulation of soil water drainage in sandy soils, laid on a ceramic plate. Comparison with experimental data
(1998)In the present paper the simulation of water movement during vertical one dimensional drainage is presented. The study is referred to uniform sandy soil samples, laid on a ceramic plate of a very small saturation hydraulic ... -
System optimal signal optimization formulation
(2006)A mixed-integer linear programming formulation is proposed to solve the combined system optimal dynamic traffic assignment and signal optimization problem. Traffic conditions are modeled with the cell transmission model, ... -
Three-dimensional convective cooling in a vertical channel with flush-mounted heat sources
(2003)Three-dimensional free convection in a vertical channel with spatially periodic, flush-mounted heat sources is investigated by a spectral element method. All numerical solutions are obtained using a time-accurate ... -
Treatment of unidentifiability in structural model updating
(2000)The present study addresses the issues of non-uniqueness and unidentifiability arising in structural model updating. A Bayesian probabilistic frame-work is used for model updating which properly handles the uncertainties ...
