When using the K-nearest neighbors method, one often ignores uncertainty in the choice of K. To account for such uncertainty, Holmes and Adams (2002) proposed a Bayesian framework for K-nearest neighbors (KNN). Their Bayesian KNN (BKNN) approach uses a pseudo-likelihood function, and standard Markov chain Monte Carlo (MCMC) techniques to draw posterior samples. Holmes and Adams (2002) focused o...

In this paper, modeling is proposed for simulating the functionality of a new waist-trunk system for humanoid robots. A 3D model of the proposed waist-trunk system has been elaborated in the MSC.ADAM® environment with the aims to investigate its dynamical operation feasibility and to characterize operation performances. Motion algorithms have been developed in the Simulink® environment for para...

We study the numerical errors in finite element discretizations of a time relaxation model of fluid motion: ut + u · ∇u + ∇p − ν∆u + χu∗ = f and ∇ · u = 0 In this model, introduced by Stolz, Adams and Kleiser, u∗ is a generalized fluctuation and χ the time relaxation parameter. The goal of inclusion of the χu∗ is to drive unresolved fluctuations to zero exponentially. We study convergence of di...

Linear programming (LP) relaxations are widely used as for finding a most likely configuration of a discrete graphical model. Whenever a linear program finds an integral solution it is guaranteed to be optimal and we say the relaxation is tight. In this paper we generalize the Sherali Adams hierarchy of LP relaxations and introduce the use of discrete Fourier Analysis to show this generalizatio...

in this paper, the deformation of a thick-walled circular cylindrical shell of incompressible isotropic elastic material is considered. the shell, which is made of three-term strain energy function is subjected to the combined external and axial loading pressure. in order to obtain the relevant eigenvalues, which is the main objective of the work, the incremental equilibrium equations are so...

in this paper, the effects of roll center height of mcpherson suspension mechanism on dynamic behaviour of a vehicle is studied first and then the optimum location of roll center of this suspension system is determined for a conceptual class a vehicle. adams/car software was used for analysis of vehicle dynamic behaviour in different positions of suspension roll center, then optimization proces...

in this research optimal reconfiguration strategy of the improved srr reconfigurable mobile robot based on force-angle stability measure has been designed using genetic algorithm. path tracking nonlinear controller which keeps robot’s maximum stability has been designed and simulated in matlab. motion equations of the robot have been derived in parametric form by means of newton- euler, lagrang...

Transient stability-constrained optimal power flow (TSCOPF) models comprehensively analyze the security and economic operation of systems. However, they require a high computational effort can suffer from convergence problems when applied to large This study analyzes performance eleven numerical integration algorithms ordinary differential equations that represent system dynamics in TSCOPF mode...
