Analysis and optimization of dynamically loaded porous metal sliding bearings under conditions of elastohydrodynamic lubrication
(2007)Purpose - This paper aims to develop a simulating model of a journal porous metal bearing under elastohydrodynamic conditions and combined (radial, friction and thermal) load distribution and to carry out structural ... -
Back pressure based multicast scheduling for fair bandwidth allocation
(2005)We study the fair allocation of bandwidth in multicast networks with multirate capabilities. In multirate transmission, each source encodes its signal in layers. The lowest layer contains the most important information and ... -
A classification system based on a new wrapper feature selection algorithm for the diagnosis of primary and secondary polycythemia
(2013)Primary and Secondary Polycythemia are diseases of the bone marrow that affect the blood's composition and prohibit patients from becoming blood donors. Since these diseases may become fatal, their early diagnosis is ... -
Classification tree based protein structure distances for testing sequence-structure correlation
(2008)A methodology for testing the correlation between the sequence and structure distances of proteins is proposed. Structure distances were derived by applying a forward growing classification tree algorithm on defined ... -
Dependence of contact area on the resolution of fractal interfaces in elastic and inelastic problems
(2011)Purpose - The purpose of this paper is to investigate the influence of the resolution with which interfaces of fractal geometry are represented, on the contact area and consequently on the contact interfacial stresses. The ... -
Effects from diaphragm wall installation to surrounding soil and adjacent buildings
(2013)A new approach for simulating the excavation and construction of subsequent panels is proposed to investigate the effects from the installation of diaphragm walls on the surrounding and adjacent buildings. The method has ... -
Evaluation of negative skin friction effects in pile foundations using 3D nonlinear analysis
(2005)The aim of this paper is to evaluate the influence of negative skin friction in pile foundations. Three dimensional nonlinear analyses for a single pile and pile groups were carried out for a specific case and some case ... -
Evaluation of the ductility features in steel structures with softening moment-rotation behaviour based on a nonconvex optimization formulation
(2000)In order to determine the ductility features of steel structures, several approaches have been introduced in the bibliography. In this paper a certain method is proposed which considers the actual form of the moment-rotation ... -
Examining the stability of genetic risk effect as evidence accumulates in the context of meta-analysis
(2013)The recursive cumulative meta-analysis (RCM) of genetic association studies explores the relative change of the cumulative risk effect (e.g. OR) in time, indicating the stability of risk effect as evidence accumulates. ... -
Explicit extension of the p-y method to pile groups in cohesive soils
(2013)Although simplified numerical methods are reliable for evaluating the response of a single pile under horizontal load, their application is questionable for assessing the response of pile groups. The notion of "p-y" curves ... -
Forest classification trees and forest support vector machines algorithms: Demonstration using microarray data
(2010)Classification into multiple classes when the measured variables are outnumbered is a major methodological challenge in -omics studies. Two algorithms that overcome the dimensionality problem are presented: the forest ... -
Friction evolution as a result of roughness in fractal interfaces
(2003)In this paper, the influence of fractal interface geometry to the evolution of the friction mechanism is studied The paper is based on fractal approaches for the modelling of the multiscale self-affine topography of these ... -
A heuristic algorithm for the buffer allocation in unreliable unbalanced production lines
(2001)In this work we investigate the buffer allocation problem (BAP) in short unbalanced production lines consisting of up to six machines that are subject to breakdowns. Times to failure are assumed exponential whereas service ... -
An implicit evolution scheme for active contours and surfaces based on IIR filtering
(2014)In this work, we present an approach for implementing an implicit scheme for the numerical solution of the partial differential equation of the evolution of an active contour/surface. The proposed scheme is applicable to ... -
Insight into the seismic response of earth dams with an emphasis on seismic coefficient estimation
(2014)This paper presents a numerical investigation of the seismic response of earth dams by employing results from 110 nonlinear two-dimensional (2D) dynamic analyses of four different cross-sections with heights ranging from ... -
Measuring biodiversity performance: A conditional efficiency measurement approach
(2010)This paper uses a methodological framework based on the new advances of Data Envelopment Analysis (DEA) and a sample of 71 developed, developing and under-developed countries to model and evaluate their biodiversity ... -
Methodology for automated GIS-aided seismic microzonation studies
(2008)This paper presents an automated methodology for performing geographic information system (GIS)-aided seismic microzonation studies. It presupposes the existence of a geotechnical database containing data from sampling ... -
MRISIMUL: A GPU-Based Parallel Approach to MRI Simulations
(2014)A new step-by-step comprehensive MR physics simulator (MRISIMUL) of the Bloch equations is presented. The aim was to develop a magnetic resonance imaging (MRI) simulator that makes no assumptions with respect to the ...
