We studied the behavior of an iterative receiver using protograph based LDPC codes (PG-LDPCC) in an UWB short range communication system. An EXIT-Chart-Analysis is applied by means of density evolution of protographs. We show that AWGN-optimized protograph ensembles perform also well on frequency-flat UWB channels, outperform rate-compatible punctured convolutional codes (RCPC), but degrade with i

Popular Abstract in Swedish Avhandlingen består av transportmätningar på AlGaAs/GaAs och GaInAs/InP heterostrukturer.This thesis consists of experimental studies of transport properties in high mobility two dimensional electron gases (2DEGs). Two material systems are used, an AlGaAs/GaAs heterojunction and a GaInAs/InP quantum well. The AlGaAs/GaAs heterojunction is used for top gating, either to additionally reduce the dimensionality of the 2DEG to observe one dimensional effects, or to explore the edge channe

People can often contribute to prosocial causes by several means; for instance, environmentally friendly activities include sorting household waste, buying organic products, and donating to NGOs. Policy to encourage prosocial behavior is sometimes directed only towards a particular activity, however, and such policies may give rise to `behavioral spillovers', affecting efforts on other prosocial a

Popular Abstract in Swedish Jesaja 40-55 representerar en av Gamla testamentets höjdpunkter. Här ackumuleras bilderna av Gud som Israels konung, herde, fader, moder, skapare och försörjare. Det är en befriande, nyskapande och mäktig Gud som tilltalar ett modlöst, förtvivlat och krossat Israel. Dessa kapitel domineras av budskapet om tröst och räddning till den grad att bibelforskningen sammanfattaThe theology of Isaiah 40-55 has two seemingly contradictory aspects: the tension between the consolatory message of deliverance, and the harsh tone of accusation. In this part of the Book of Isaiah, YHWH's return to his people is demonstrated through the accumulation of declarations about YHWH's ability and his will to deliver the Israelites from the exile. At the same time, the Israelites are ex

Abstract : This collection of ten essays adds a new and original perspective to the debate on political reform in the Gulf countries which has intensified in recent years. Rather than couching the issue in the more frequently heard terms of authoritarianism vs. democratization, the book focuses on the evolution of Gulf constitutions and on the widening of political participation. It is shown that

Athos Protaton 86) utgiven av Britt Dahlman och en svensk översättning av den systematiska samlingen av Apophthegmata Patrum (Ökenfädernas tänkespråk), bok 7. Översättningen har gjorts gemensamt av deltagarna i översättningsseminariet vid Johannesakademin.The book contains a Greek text (based on MS Athos Protaton 86) edited by Britt Dahlman and a Swedish translation of the Systematical collection of the Apophthegmata Patrum, book 7. The translation was made jointly by the participants in the translation seminar at Johannesakademin.

Popular Abstract in Swedish VIKTEN AV HETEROGENA JORDBRUKSMILJÖER FÖR GRÅSPARVEN Under de senaste 40 åren har vårt odlingslandskap genomgått kraftiga strukturella förändringar som en konsekvens av att jordbruket har intensifierats och effektiviserats. Dessa förändringar har möjliggjort en nödvändig, ökad produktion av spannmål och andra grödor men samtidigt har det haft förödande konsekvenser på dStrong declines of European farmland birds in recent decades are assumed to be caused by decreased food availability resulting from agricultural intensification and concomitant loss of farmland heterogeneity. One of the species suffering particularly strong declines in NW European countries is the house sparrow. In this thesis I investigated the importance of farmland land-use on house sparrow eco

Fortresses, Storehouses and Symbols - ambiguous churches of the Baltic Sea: Källa on Öland is used as a point of departure in a discussion of the so-called defensive churches or multi-functional churches at the Baltic Sea. The categorization of medieval society into four separate spheres, the church, the castle, the town and the countryside, is criticised as having created a heterogenous group of
