1. Intermediation in Business Networks: A Case Study in the Textile and Clothing Industry
Sammanfattning : Intermediation is a central concept in the marketing channel literature where it is used for analyzing how specific firms, intermediaries, connect producers and users. It is argued that intermediation is primarily about increasing transaction efficiency when intermediaries undertake functions for closing the gap between producer stocks and consumer assortments, thus bridging discrepancies in time and place between supply and demand.

2. Estimation and detection of transmission line characteristics in the copper access network
Sammanfattning : The copper access-network operators face the challenge of developing and maintaining cost-effective digital subscriber line (DSL) services that are competitive to other broadband access technologies. The way forward is dictated by the demand of ever increasing data rates on the twisted-pair copper lines. LÄS MER
3. On error-robust source coding with image coding applications
Sammanfattning : This thesis treats the problem of source coding in situations where the encoded data is subject to errors. The typical scenario is a communication system, where source data such as speech or images should be transmitted from one point to another. A problem is that most communication systems introduce some sort of error in the transmission. LÄS MER
4. Sparse Array Architectures for Wireless Communication and Radar Applications
Sammanfattning : This thesis focuses on sparse array architectures for the next generation of wireless communication, known as fifth-generation (5G), and automotive radar direction-of-arrival (DOA) estimation. For both applications, array spatial resolution plays a critical role to better distinguish multiple users/sources. LÄS MER
