In this paper, multiple-input multiple-output (MIMO) channel measurements in an outdoor micro-cell environment are used to study the effect of base-station (BS) inter-element spacing on multi-user MIMO signal separation. Users with two dual-polarized patch antennas at the mobile station (MS), and four equally-spaced dual-polarized patch antennas at the BS are considered. At the BS, the inter-eleme
The convergence of the Internet and Telecommunication Architectures is a key issue in today’s telecommunication world. It is foreseen that future versions of UMTS will be all-IP based, and therefore the interest in this area is increasing. The focus in this paper is to show how to access IN-services from the Internet and other IP-based networks. Previous research of the interworking between PSTN a
Förutom att vara en uppskattning av Håkan Lundström är detta en bok av intresse för alla som funderar i konstnärliga termer och framför allt i en akademisk miljö. Boken består av en mosaik av idéer om allt möjligtsom ryms under det konstnärliga idéparaplyet och som har något slags anknytning till festföremålet. Utgångspunkten är drongo-fågeln som är en metafor för längtan i kammudiktningen, som haApart from appealing to those who know and appreciate Håkan, this book is likely to interest the artistically inclined, particularly those in an academic environment. It is a mosaic of texts, more than a mere memorial, that allows us to accompany Håkan on a journey to many of the places contained under the artistic umbrella, especially those which happen to have a more intimate connection with our
In the present study, the effects of a single rib on the local heat transfer around a bluff body are examined by using the steady state liquid crystal technique. By varying the spacing between the bluff body and the rib, the interaction between the rib and the bluff body can be controlled. The bluff body is oriented vertically towards the flow direction and spans the whole height of the channel. T
This article concerns the co-evolution of hominin cooperation, communication and cognition. Certain hominin ecologies seem to have relied on cognitive foresight. The capacity of planning for future needs, combined with more developed cooperative skills, opened up the cognitive niche of cooperation towards future goals. Such cooperation requires complex intersubjectivity (theory of mind). We analyz

Popular Abstract in Swedish Upptag och omsättning samt dosimetri för 14C märkt fett, urea, gallsyra och xylos, i människa. Kol-14 (14C) används som radioaktivt spårämne vid patientundersökningar inom sjukvården och utnyttjas i stor utsträckning vid medicinsk forskning och vid utprovning av nya läkemedel på frivilliga försökspersoner. Eftersom 14C har mycket lång fysikalisk halveringstid (5730 år)14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. In this work detailed long-term biokinetic and dosimetric estimation have been carried out for four clinically used 14C-breath tests: 14C-triolein (exam
The Messiah neatly surveys currents of messianic thought in the formative centuries of Judaism and Christianity, providing precision in thinking about "messianic" images and tradition. Leading scholars offer succinct and illuminating essays on the traditions that decisively shaped Jewish and Christian belief in a messiah. Includes two maps, a timeline of persons, events, and literature, and a glos
This paper presents an adaptive signal management Modelica library, “SignalFlow”, interconnected with a C++ class library. The objective is to simplify the signal exchange in large simulation models based on modular designs, which should correspond to the signal flow for real applications by representing common networks as models with general interfaces. The library enables automatic configuration
