1. 16. Colorimetric and Multispectral Image Acquisition

   Författare :Daniel Nyström; Björn Kruse; Carl-Magnus Fahlcrantz; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Spectral reconstruction; Device characterization; Image analysis; Bildanalys;

   Sammanfattning : The trichromatic principle of representing color has for a long time been dominating in color imaging. The reason is the trichromatic nature of human color vision, but as the characteristics of typical color imaging devices are different from those of human eyes, there is a need to go beyond the trichromatic approach.

4. 18. Cross-Layer Optimization of Voice over IP in Wireless Mesh Networks

   Författare :Peter Dely; Andreas Kassler; Dirk Staehle; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

   Sammanfattning : Wireless Mesh Networks (WMNs) have emerged as a promising network technology, which combines the benefits of cellular networks and Wireless Local Area Networks (WLANs). In a WMN mesh routers wirelessly relay traffic on behalf of other mesh routers or clients and thereby provide coverage areas comparable to cellular networks, while having the low complexity and low costs of WLANs.

   Sammanfattning : In recent years, the rapid growth in wireless data traffic has posed not only unique opportunities but also great challenges for the wireless industry. In order to meet the growing demand without excessive cost or energy consumption, one feasible option for the operators is to acquire more spectrum for wireless communication. LÄS MER

7. 20. Experimental Verification of Superconductor Digital Circuits

   Författare :Henrik Engseth; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cryocooler.; Superconductivity; Multi Chip Modules MCM ; high frequency test; Rapid Single Flux Quantum RSFQ logic; heatload;

   Sammanfattning : AbstractSuperconducting digital technology based on Rapid Single Flux Quantum (RSFQ) logic offers a 50 times faster clock rate and 100 times less on chip power consumption than today's mainstream semiconductor electronics. This technology is attractive for many applications and in particular for Digital Signal Processing (DSP). LÄS MER
