An Optimization Approach to Indoor Location Problem Based on Received Signal Strength
… through the implementation of a low-cost indoor location system using received signal devices. Indoor location through received signal strength (RSS) is of low costs, yet it suffers from poor accuracy due to lack of direct line-of-sight, multi-path ratio propagation, and various interferences. To …

Investigating the Maximal Coverage by Point-based Surrogate Model for Spatial Facility Location Problem
Spatial facility location problems (SFLPs) involve the placement of facilities in continuous demand regions. One approach to solving SFLPs is to aggregate demand into discrete points, and then solve the point-based model as a conventional facility location problem (FLP) according to a surrogate …

A Discrete Optimization Approach to Solve a Reader Location Problem for Estimating Travel Times
… using AVI tag readers fixed at certain specific locations. This thesis focuses on devising an efficient methodology to capture as much travel time information as possible, by solving a Reader Location Problem that maximizes the benefit accruing from measuring travel time variability with respect …

Nonparametric multivariate multisample tests of the location problem and multivariate regression based on directions of data
Randles' one sample multivariate sign test based on interdirections is extended to two sample and multisample tests. A heuristic argument suggests that when samples are drawn from elliptically symmetric distributions all of these tests share the same asymptotic relative efficiency with respect to …
