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

Tracking degradation in software product lines through measurement of design rule violations

In order to increase reuse, a number of product versions may be)", developed based on the same software platform. The platform must, however, be managed and updated according to new requirements if it should be reusable in a series of releases. This means that the platform is constantly changed during its lifecycle, and changes can result in degradation of the platform. In this paper, a measuremen
