Description of Telia's OFDM-based proposal

This document give an overview of Telias OFDM based proposal for UTRA and should be considered as an input to the OFDM concept group within SMG 2. The document describe the fundamental frame structure, principles of the detection, modulation, coding and synchronisation. Further on the channel structure, the resource management and handover principles are outlined.

Nutrient Limitation of Bacterial Growth in Soil

Lack of carbon has been assumed to be the most common limiting factor for bacterial growth in soil, although there are reports of limitation by nitrogen and phosphorus. I have studied nutrient limitation of bacterial growth in soil using a novel technique, where thymidine or leucine incorporation is used to detect changes in growth rates after adding nutrients. I have studied which nutrient(s) li

Performance Evaluation of a High Solar Fraction CPC-Collector System

One of the most important goals on solar collector development is to increase the system’s annual performance without increasing overproduction. The studied collector is formed by a compound parabolic reflector which decreases the collector optical efficiency during the summer period. Hence, it is possible to increase the collector area and thus, the annual solar fraction, without increasing the o

Competition and barriers to entry the construction sector

In 1999 Sweden and Denmark were physically, linked for the first time by, a bridge bringing the countries even closer. The bridge connects the capital area of Denmark and the south part of Sweden in an area called the Oresund region. At a national level there is a mutual political interest to create an integrated market in the Oresund region and in a wider perspective the bridge is a physical cont

On unequal error protection for information symbols via active distances

This paper describes the active burst distance for convolutional codes. The unequal error protection for information sequences are used to formulate a theorem on the error-correcting capability of the generator matrix and set state paths in the encoder state-transition diagram correspond to code sequences. Therefore the active-distance concepts are used to characterize the error patterns
