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

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

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

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

A "compass rose" pattern sometimes appears when stock returns are plotted against themselves with a one-day lag, since stock prices move in discrete steps. In this paper, we perform a Monte Carlo study on simulated stock price series rounded in different ways to mirror the behavior of stocks on the Stockholm Stock Exchange. We find AR-GARCH parameter estimates to be affected by the discreteness im

Occasional verse and orations in separately printed leaflets at funerals, weddings and other celebrations was the dominant vehicle for literary production in Sweden in the 17th and 18th centuries. It honoured the recipients and promoted the authors. This aspect of print culture in the Swedish Age of Greatness is here summarized.

Listening Lund Sound environment centre at Lund university in Sweden is known to be the first interdisciplinary centre created with an aim to coordinate research on sound and sound environmental issues. Ranging från acoustics to medicin to juridics as well to humanities as musicology and ethnology sound environmental research adresses many interdepentent areas and topics. To be able to get a more
