2. 1. Equal opportunities? : a cross-national comparison of immigrant organisations in Sweden and Italy

   Author : Roberto Scaramuzzino; Malmö högskola; []
   Keywords : corporatism; social welfare; integration; civil society; diversity; political opportunity structures; resource mobilisation; cross-national research; immigrant organisations;

   Abstract : Abstract This thesis concerns the role played by immigrant organisations today. It focuses on the way in which the national context and especially the corporative, social welfare, and integration systems affect such roles. READ MORE

4. 2. Stability analysis of channel flow laden with small particles

   Author : Joy Klinkenberg; Luca Brandt; Cristian Marchioli; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transition; modal analysis; non-modal analysis; Direct Numerical Simulations; multi-phase flow; heavy particles; light particles; particle-laden;

   Abstract : This thesis deals with the stability of particle laden flows. Both modal and non-modal linear analyses have been performed on two-way coupled particleladen flows, where particles are considered spherical, solid and either heavy or light. When heavy particles are considered, only Stokes drag is used as interaction term. READ MORE

5. 3. On Modulation and Detection Schemes for Low-Complexity Impulse Radio UWB Communications

   Author : Muhammad Gufran Khan; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UWB; RAKE; Transmitted reference; Energy detection; Channel measurements; BPPM;

   Abstract : Due to wealth of advantages offered by short range ultra wideband (UWB) technology, such as capacity improvement, fading reduction and localization, it has gathered a considerable attention. Distinct UWB qualities also pose many system design challenges like difficulties in using digital processing, complex channel estimation and different propagation characteristics. READ MORE

6. 4. Optimization of Joint Cell, Channel and Power Allocation in Wireless Communication Networks

   Author : Mikael Fallgren; Anders Forsgren; Zhi-Quan (Tom) Luo; KTH; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Wireless multicell networks; Optimization; OFDMA; Shannon capacity; Complexity; NP-hard; Relays; Allocation problems; Heuristic algorithms;

   Abstract : In this thesis we formulate joint cell, channel and power allocation problems within wireless communication networks. The objectives are to maximize the user with mini- mum data throughput (Shannon capacity) or to maximize the total system throughput, referred to as the max-min and max-sum problem respectively.

7. 5. Fast Power Control to Counteract Rayleigh Fading in Cellular Radio Systems

   Author : Anders Ericsson; Mille Millnert; Linköpings universitet; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In urban areas, cellular radio signals are subject to Rayleigh fading, which results in rapid changes in the channel gain. For TDMA-systems without the possibility of frequency hopping, this can cause severe problems for slowly moving cellular phones. READ MORE
