Popular Abstract in Swedish Bostäder och service svarar för hela 36 procent av Sveriges totala energianvändning, av detta står bostäder och lokaler för ungefär 86 procent. Den svenska riksdagen har antaget EU: s klimat-och energipolitiska mål som skall nås till 2020, som kallas "20-20-20"-målen. EU:s 20-20-20-mål innebär att vi ska minska klimat¬påverkan med 20 procent, uppnå 20 procent förnybar eUsing energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. Pre-heating the incoming outdoor air reduces the need to heat ventilation and reduces the need for high-quality energy such as electricity or he

The paper presents a revised definition of the mean effective gain (MEG) of terminal antennas. It now includes the gain pattern of both the transmitting (BS) and receiving (MS) antennas, the path gain matrix as well as the joint angular power distributions of the two orthogonal polarizations at both ends. A closed form equation is provided followed by the analysis of some special cases and their p

When designing a new basic course in statistics for students in Environmental Engineering at Lund University, our aim was that assessment should be an integral part of the course. We found that there were several factors to be considered, such as how the assessment should be in line with the goals of the course and with the teaching method. One piece of the assessment is a major project and we dis

The paper examines in selected detail, issues of maritime security in international law that are currently at the forefront of concerns in the maritime world. It provides an overview of the nature of maritime security contra maritime safety and gives an introduction of the most common threats. It looks at the current scenario in light of what is evolving in response to certain dramatic events of t

The channel properties have a large influence on user separability in massive multi-user multiple-input multiple-output (massive MIMO) systems. In this paper we present spatio-temporal characteristics obtained from massive MIMO channel measurements at 2.6 GHz. The results are based on data acquired in both indoor and outdoor scenarios where a base station equipped with 64 dual-polarized antenna el

Latency of available channel state information (CSI) at the transmitter in time-varying channels greatly affects the performance of multiple-input multiple-output (MIMO) systems. We have derived a simple algorithm to calculate an approximation of the expected performance loss based on the most recent channel feedback. The proposed algorithm can be used to determine the maximum tolerable channel fe

I föregående nummer av samfundets tidskrift behandlades olika aspekter på missbruk av marknadsdominerande ställning inom den europeiska ekonomiska gemenskapen – EEC. I denna artikel diskuteras motsvarande problem från en svensk utgångspunkt med stöd av då gällande konkurrenslagstiftning.

Popular Abstract in Swedish Kvinnor som har slutat röka löper ökad risk att drabbas av bröstcancer. Denna slutsats baseras på en uppföljning av drygt 10.000 kvinnor som på 70- och 80-talen deltog i en hälsoundersökning på avdelningen för Förebyggande Medicin i Malmö. Genom att samköra denna databas med det svenska cancerregistret har det varit möjligt att spåra hur många av rökarna, ex-rökarna ochEx-smokers are exposed to a higher breast cancer risk than are never smokers. This conclusion is based on a follow-up of the 10 902 women in the Malmö Preventive Project. The 31% higher incidence in ex-smokers remained statistically significant when other risk factors were taken into account in the analysis. In both smokers and ex-smokers there was an increased incidence of oestrogen receptor nega

This paper presents the Reed-Solomon (RS) decoder for multiband OFDM(MB-OFDM) ultra-wideband(UWB). In UWB system, RS (23,17) code is adopted. To achieve high throughput and small area, two iterative Modified Euclidean (ME) blocks are proposed to work by turns in this paper. The architectures of syndrome block, ME block, Chien search block, Forney block are presented later in detail. At last, this
