Commercial applications for the location of subscribers of wireless services continue to expand. Consequently, finding the CramerRao bound (CRB), which serves as an optimality criterion for the location estimation problem, is of interest. In this article, we derive the CRB for the estimation of channel parameters and mobile position in an asynchronous direct sequence code division multiple acce...

BACKGROUND Global performance rating is frequently used in clinical training despite its known psychometric drawbacks. Inter-rater reliability is low in undergraduate training but better in residency training, possibly because residency offers more opportunities for supervision. The low or moderate predictive validity of global performance ratings in undergraduate and residency training may be ...

In this paper we derive a criterion for the breakdown of classical solutions to the incompressible magnetohydrodynamic equations with zero viscosity and positive resistivity in R3. This result is analogous to the celebrated Beale-KatoMajda’s breakdown criterion for the inviscid Eluer equations of incompressible fluids. In R2 we establish global weak solutions to the magnetohydrodynamic equation...

For each hotel, we have the following information: ? Name: the name of the luxury hotel; ? Total of negative words (criterion 1): the total number of negative words in all the comments given by the clients of this hotel. (criterion to be minimized); ? Total of positive words (criterion 2): the total number of positive words in all the comments given by the clients of this hotel. (criterion to b...

In this paper, we present the influence of the presence of a mobile platform on manipulability measure. We propose a normalized measure to solve problems inherent to physical units and velocity limits of the system. Simulation results on three dimensional positioning task are given to show the effect of nonholonomic constraint on manipulability measure. Manipulability is a well-established tool...

This paper addresses the problem of tracking feature points along image sequences to analyze the undergoing human movement. An approach based on Kalman filtering performs the estimation and correction of the feature point’s movement in every image frame, and optimizes the incorporation of the measured data in order to establish the best global correspondence. We propose a criterion to establish...

Abstract. The photon map method allows efficient computation of global illumination in general scenes. Individual photon hits, generated using Monte Carlo particle tracing, are stored in the maps and form a geometry independent representation of the illumination. Two important issues with the photon map are memory requirements to store the photons and the question how many photons are needed fo...

A novel approach to the Bayesian Information Criterion (BIC) is introduced. The new criterion redefines the penalty terms of the BIC, such that each parameter is penalized with the effective sample size is trained with. Contrary to Local-BIC, the proposed criterion scores overall clustering hypotheses and therefore is not restricted to hierarchical clustering algorithms. Contrary to Global-BIC,...

We propose a new and rather stringent criterion for testing the goodness of fit between a theory and experiment. It is motivated by the paradox that the criterion on χ2 for testing a theory is much weaker than the criterion for finding the best fit value of a parameter in the theory. We present a method by which the stronger parameterfitting criterion can be applied to subsets of data in a glob...

In this paper we address the problem of tracking feature points along image sequences. To analyze the undergoing movement we use a common approach based on Kalman filtering which performs the estimation and correction of the feature point’s movement in every image frame. The criterion proposed to establish correspondences, between the group of estimates in each image and the new data to include...
