In this paper, we propose a novel matchedfilter-type parallel code acquisition scheme to detect uplink short-code wideband CDMA multipath signals. A treestructured parallel adaptive network of RAKE fingers is created for all possible delay shifts and users. Employing a sequential detection scheme, only viable fingers are used to generate the output decision statistics. Monte Carlo computer simu...

Top-hat monopole antennas loaded with radially layered dielectric are analyzed using the finite-difference time-domain (FDTD) method. Unlike the mode-matching method (MMM) (which was previously used for analyzing these antennas) the FDTD method enables us to study such structures accurately and easily. Using this method, results can be obtained in a wide frequency band by performing only one ti...

langevin equation for a nano-particle suspended in a laminar fluid flow was analytically studied. the brownian motion generated from molecular bombardment was taken as a wiener stochastic process and approximated by a gaussian white noise. euler-maruyama method was used to solve the langevin equation numerically. the accuracy of brownian simulation was checked by performing a series of simulati...

in this paper, a bayesian approach is proposed for shift point detection in an inverse gaussian distribution. in this study, the mean parameter of inverse gaussian distribution is assumed to be constant and shift points in shape parameter is considered. first the posterior distribution of shape parameter is obtained. then the bayes estimators are derived under a class of priors and using variou...

This study illustrates the application of conditional simulations to calculate uncertainty associated with thickness bauxite ores. The deposit Rondon do Pará in northern State, Brazil, is characterized by a well-defined lateritic profile, ore being composed two sequential horizons: massive and ferruginous bauxite. used data from 1.005 drillholes different grid spacing. Drillhole intervals both ...

ÐGenerated realizations of random ®elds are used to quantify the natural variability of geological properties. When the realizations are used as inputs for simulations with a deterministic model, it may be desirable to minimize di€erences between statistics of sequential realizations and make the statistics close to ones speci®ed at generating the realizations. We describe the use of a genetic ...

Most small-scale simulation applications are implemented by sequential simulation techniques. As the problem size increases, however, sequential techniques may be unable to manage the time complexity of the simulation applications adequately. It is natural to consider re-implementing the corresponding largescale simulations using parallel techniques, which have been reported to be successful in...
