Analysis of Lateral Transshipments in Inventory Systems

This thesis is based on two scientific papers. In these papers we study how one can approximate the inventory level of probabilities and the transshipment rates for inventory systems that apply lateral transshipment policies. Both papers consider a single-echelon inventory system consisting of a number of parallel installations, which all face Poisson demand. Normally, the installations replenish

Source reconstruction by far-field data for imaging of defects in frequency selective radomes

In this paper, an inverse source reconstruction method with great potential in radome diagnostics is presented. Defects, e.g. seams in large radomes, and lattice dislocations in frequency selective surface (FSS) radomes, are inevitable, and their electrical effects demand analysis. Here, defects in a frequency selective radome are analyzed with a method based on an integral formulation. Several fa
