Capacitive Circuit Method for Fast and Efficient Design of Wideband Radar Absorbers

A simple, fast and efficient method for designing wideband radar absorbers is proposed. The idea is to modify the circuit analog absorber method without perturbing the bandwidth. This is done by utilizing the asymptotic behavior of such an absorber at low frequency and replacing the band-stop resonating frequency selective surfaces with low-pass capacitive ones, which can be synthesized by square

Decision-making in health issues: Teenagers' use of science and other discourses

The purpose of this thesis is to develop knowledge about young individuals’ reasoning and how they justify their standpoints concerning trustworthiness and decision-making in issues connected to health where available information is contradictory or uncertain. This purpose has been addressed in three different steps. In the first step almost 300 students in Swedish upper secondary school answered

Procurement Performance Measurement System

The procurement process can be defined as all the activities required in getting a product or a service from the supplier to a final destination. It encompasses the purchasing function, storing, transportation and manages the relations between suppliers and internal customers. It is a cyclical process involving the following activities: analysis, planning, implementation, and measurement. The perf

Angle sizes for pointing gestures

One factor which can be expected to influence performance in applications where the user is expected to point a device in some direction to obtain information is the angle interval in which the user gets feedback. The present study was performed in order to get a better understanding of the influence of this angle interval on navigation performance, gestures and strategies in a more realistic outd

Coordinated control of Multi-Stage Inventory System

This thesis is based on three scientific papers dealing with different models for coordinated control of multi-stage inventory systems. The ability to control multi-echelon inventory systems, is paramount for reducing tied up capital and inventory costs in large distribution systems. It is also one key issue in achieving efficient supply chain management. We focus our attention on a general distr
