Non-simulation techniques for comparison of multisensor probabilistic data association lters are developed and are used to compare tracking performance of sequential and parallel implementations of the algorithm. The non-simulation techniques are shown to accurately predict the average superior performance of the sequential implementation in terms of RMS position error and track lifetime which ...

Stochastic seismic inversion is a family of inversion algorithms in which the inverse solution was carried out using geostatistical simulation. In this work, a new 3D stochastic seismic inversion was developed in the MATLAB programming software. The proposed inversion algorithm is an iterative procedure that uses the principle of cross-over genetic algorithms as the global optimization techniqu...

Abstract This study focuses on constructing a 3D geo-cellular model by using well-log data and other geological information to enable deep investigation of the reservoir characteristics estimation hydrocarbon potential in clastic marginal field offshore Vietnam. In this study, Petrel software was adopted for geostatistical modeling. First, sequential indicator simulation (SIS) facies Next, Gaus...

[1] The influence of aquifer property correlation on multiphase fluid migration and entrapment was explored through the use of correlated and uncorrelated porosity, permeability, and capillary pressure-saturation (Pc-Sat) parameter fields in a crosssectional numerical multiphase flow model. Data collected from core samples in a nonuniform sandy aquifer were used to generate three-dimensional aq...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

Concentrations of four heavy metals (Cr, Cu, Ni, and Zn) were measured at 1,082 sampling sites in Changhua county of central Taiwan. A hazard zone is defined in the study as a place where the content of each heavy metal exceeds the corresponding control standard. This study examines the use of spatial analysis for identifying multiple soil pollution hotspots in the study area. In a preliminary ...

A fast fault simulation approach based on ordinary logic emulation is proposed. The circuit configured into our system that emulates the faulty circuit’s behavior is synthesized from the good circuit and the given fault list in a novel way. Fault injection is made easy by shifting the content of a fault injection scan chain or by selecting the output of a parallel fault injection selector, with...

this paper extends the sequential learning algorithm strategy of two different types of adaptive radial basis function-based (rbf) neural networks, i.e. growing and pruning radial basis function (gap-rbf) and minimal resource allocation network (mran) to cater for on-line identification of non-linear systems. the original sequential learning algorithm is based on the repetitive utilization of s...
