This paper investigates the implementation of a novel wireless local positioning system (WLPS). WLPS main components are: (a) a dynamic base station (DBS) and (b) a transponder, both mounted on mobiles. The DBS periodically transmits ID request signals. As soon as the transponder detects the ID request signal, it sends its ID (a signal with a limited duration) back to the DBS. Hence, the DBS re...

We represent the Brownian model for continuous traits with phylogenetic dependence as a variance components model, allowing for the novel estimation of edge weights for every branch of a tree graph. We show that maximum likelihood estimation carries an inherent bias often shrinking internal edges to zero, which is troublesome because this estimate is intended to compare covariance structures as...

Longitudinal data refers to datasets with multiple measurements of a response variable on the same experimental unit made over a period of time. These types of data require special attention because they involve correlated data. The relationships between repeated measurements are important in assessing reliability and tracking of those measurements. The proper variancecovariance structure in th...

The non-linear inverse problem is formulated in a Bayesian framework. The multivariate normal distribution is assumed in both the noise and prior distributions. However, only the structures of the covariance matrices have to be specified, estimation of the variance levels is included in the inversion procedure. The maximum a posteriori approximation is derived, and the final result is a weighte...
