Window decoding schedules are very attractive for message passing decoding of spatially coupled LDPC codes. They take advantage of the inherent convolutional code structure and allow continuous transmission with low decoding latency and complexity. In this paper we show that the decoding complexity can be further reduced if suitable message passing schedules are applied within the decoding window.

In this paper the problem of modeling and design by using an ontology-based methodology is addressed. Ontology is a pretty new concept in the robotics fields. However, developing an example we will show that important advantages can be obtained in terms of design and robustness. The crucial point will be the definition of compound tasks, devices, and skills to facilitate the reasoning on different

Over the years, two strands of thought on Sustainable Development (SD) have emerged, often identified as ecologism and environmentalism, respectively. This paper suggests that there exists a third rhetorically excluded option, namely large-scale industrial expansion into space. Access to raw materials found on the Moon as well as unfiltered solar energy would dramatically increase the stock of res

Rapporten beskriver hur subjektiva faktorer påverkar medborgarnas uppfattning av staden och deras beteende, samt hur man kan bedöma eller mäta dessa faktorer. Vad som ingår i dessa faktorer resp. vilka indikatorer som speglar dem diskuterades först med ansvariga från olika kommuner i Sverige. 16 personer från11 kommuner intervjuades med detta syfte. Resultaten från intervjuerna sammanfattas i denn

Popular Abstract in Swedish Bakgrund Varje år dör omkring 700 malmöbor av hjärtinfarkt, av dessa är var tredje yngre än 75 år. Den bakomliggande sjukdomen, åderförkalkning, leder till en successiv tilltäppning av hjärtats kranskärl. Hjärtinfarkten, som alltså innebär att en del av hjärtmuskeln går under, beror på att det till slut bildas en blodpropp som täpper till kärlet helt och hållet. Att inMalmö (pop. 250 000) is a city in the south of Sweden where there are marked intra-urban differences in the mortality rates from myocardial infarction. This thesis, which is based on local and national morbidity and mortality registers and two prospective population-based cohort studies, should be considered as an attempt to explore if and how morbidity and mortality patterns co-vary with the prev

Abstract in French L’approche phénoménologique induit le chercheur vers une collecte de données aussi libre que possible, évitant toute construction de sens de la part du chercheur tant au niveau des questions que des réponses. Il s’agit d’obtenir, de la part du sujet invité à une participation active à la recherche, un texte exprimé d’une facon aussi libre et spontanée que possible, dévoilant ses

Designs for Extremely Large Telescopes (ELTs) are quite well advanced,but the requirements of instruments have had limited impact. Sinceprovision of a suitable environment for instruments is a critical aspectof all telescopes, we outline some well-known and some less-appreciatedchallenges of designing instruments for ELTs. A wide-field spectrometer(WFSPEC) with ~10 arcmin field-of-view, probably w

Endometrial prostaglandins (PGs) and the PGE2/PGF2alpha ratio play an important role in regulating the estrous cycle and establishment of pregnancy. The enzymes downstream of cyclooxygenase-2 may determine the PGE2/PGF2alpha ratio in the porcine uterus. Thus, we have cloned porcine PGF synthase (PGFS) and microsomal PGE synthase-1 (mPGES-1) and characterized their expression in porcine endometrium
