Aggregated bandwidth allocation: Investigation of performance of classical constrained and genetic algorithm based optimisation techniques
(2002)We consider a high speed integrated services network, and investigate compare and contrast the performance of two algorithms for solving the Aggregated Bandwidth Allocation (BA) problem. The algorithms we focus our attention ...

Approximating standard cell delay distributions by reformulating the most probable failure point
(CEUR-WS, 2016)The delay distribution of a digital circuit path is crucial for the early reliability evaluation of a digital design. As transistors are shrunk to unprecedented dimensions, accurate yet fast estimation of such distributions ...

Brownian-like kinematics of ball milling for particulate structural modeling
(2016)Ball milling motion has been previously studied through computationally expensive, off-line experimental video processing and numerical simulations by the discrete element method. This research establishes a more efficient ...

Conditional densities for continuous-time nonlinear hybrid systems with applications to fault detection
(1998)Continuous-time nonlinear stochastic differential state and measurement equations, all of which have coefficients capable of abrupt changes at a random time, are considered; finite-state jump Markov chains are used to model ...

A DFT study of the ground state multiplicities of linear vs angular polyheteroacenes
(2004)Unrestricted density functional calculations in combination with the broken-symmetry approach and spin-projection methods have been employed to study a series of formally 4n π antiaromatic linear and angular polyheteroacenes. ...

First-passage study and stationary response analysis of a BWB hysteresis model using quasi-conservative stochastic averaging method
(1995)The quasi-conservative stochastic averaging (QCSA) method is applied to a Bouc-Wen-Baber hysteretic system (BWB) under Gaussian white noise excitations. The stationary probability density of the system's response amplitude ...

A graph-theoretic network security game
(2005)Consider a network vulnerable to viral infection. The system security software can guarantee safety only to a limited part of the network. We model this practical network scenario as a non-cooperative multi-player game on ...

Mapping of data obtained on driving simulator to reality based on simulator validation results (WIP)
(The Society for Modeling and Simulation International, 2014)The use of a driving simulator can be preferable to on-road experiments for cost-efficient rapid prototype testing or dangerous driving scenario evaluations. However, the mismatch of the simulator and the actual driving ...

Measurement of the top-quark mass with dilepton events selected using neuroevolution at CDF
(2009)We report a measurement of the top-quark mass Mt in the dilepton decay channel tt̄→bl′+νl′b̄l-ν̄l. Events are selected with a neural network which has been directly optimized for statistical precision in top-quark mass ...

Modeling change of haplotype distributions in random mating populations using random sets
(2004)Several mathematical models have been developed to describe the genetic structure of populations. Most of these models focus on only one, or few genetic loci. In this paper, we develop a model to describe a large number ...

On comparing several spectral densities
(2008)We investigated the problem of testing equality among spectral densities of several independent stationary processes. Our main methodological contribution is the introduction of a novel semiparametric log-linear model that ...

Optimizing the utility function-based self-adaptive behavior of context-aware systems using user feedback
(2008)The vision of ubiquitous computing is about numerous devices embedded in our every-day environment, designed to serve humans in a non-obtrusive manner while minimizing the required user attention. These devices are expected ...

Precise measurement of the top-quark mass in the lepton+jets topology at CDF II
(2007)We present a measurement of the mass of the top quark from proton-antiproton collisions recorded at the CDF experiment in Run II of the Fermilab Tevatron. We analyze events from the single lepton plus jets final state ...

Search for a W1 Boson decaying to a top and bottom quark pair in 1.8 TeV pp̄ collisions
(2003)A study was performed to search for the production of a new heavy vector gauge boson in 1.8 TeV p̄p collisions and decaying into the tb final state. No evidence was obtained for a signal above the expected background ...

Statistical analysis of multipath fading channels using generalizations of shot noise
(2008)This paper provides a connection between the shot-noise analysis of Rice and the statistical analysis of multipath fading wireless channels when the received signals are a low-pass signal and a bandpass signal. Under certain ...

Stochastic models for short-term multipath fading channels: chi-square and Ornstein-Uhlenbeck processes
(IEEE, 1999)This paper discusses the use of stochastic differential equations to model signal envelope variations over areas, which are subject to short-term fading effects. The short-term fading effects are modeled using Ornstein-Uhlenbeck ...
