Massive MIMO has been shown, both in theory and through experiments, to offer very promising properties. These include the possibility to decrease output power by at least an order of magnitude while still achieving large gains in spectral efficiency, as compared to today’s access schemes. To efficiently design communication algorithms and evaluate massive MIMO schemes, channel models that capture

To remain effective within the public procurement proc-ess it is important to avoid revisions on contract award deci-sions, which prolong the procurement process and takes its toll on public resources. This paper aims to delineate the grey zone within public procurement legislation and clarify how the court interprets it, which will aid procurement officers in achieving best practice. Findings ind

Outdoor positioning systems are commonly available and typically rely on satellite navigation. The same is not true for indoor positioning systems. Severe multipath, non line-of sight to satellites and moving objects are some of the aspects that make the task of indoor positioning tricky. In this paper, we analyse different tracking methods to estimate and track the delay evolution of a radio chan

Aim: To present the utilization of a highly interactive, internet-based, package for ophthalmological content. Summary of work: The clinical ophthalmology rotation in Malmö is a 6 weeks on-campus period integrated with ENT. Weekly interactive internet-based theory parts include, (1) a PBL scenario (pathophysiology and basic sciences), (2) a series of case presentations (management principles), (3)

A series of comparative studies is suggested, focused on perceptions of outrigger canoes, and aimed at an increased understanding of the relationship between social relations, biodiversity, and sustainable development in Oceanic societies on small islands and in coastal areas undergoing rapid cultural change. After a critique of the recent notion that canoe-building in Polynesia developed as a res

A strain-independent feeding strategy for fed-batch cultures of Escherichia coli is presented. The key idea is to exploit a characteristic change in the cell metabolism at the onset of acetate formation. By superimposing short pulses in the glucose feed rate, on-line detection of acetate formation can be made using a standard dissolved oxygen sensor. A simple feedback algorithm is then us

Popular Abstract in Swedish Ju tidigare man kan upptäcka sjukdomskopplade förändringar i kroppen, desto större är chansen att bli frisk och överleva sjukdomen. Molekylär avbildning är ett nytt forskningsfält som vuxit fram de senaste årtiondena som svarar mot detta önskemål. Målet är att så tidigt som möjligt kunna avbilda de förändringar som ger upphov till sjukdomen, snarare än att som idag, avbThe earlier abnormalities coupled with disease can be discovered in the body, the larger is the chance to survive the disease. Molecular imaging is a growing research field which aims to detect these abnormalities at a molecular level, when the chance of survival is still high. The main idea of molecular imaging is to use target specific contrast agents that accumulate at the diseased region at a

Regional cerebral blood flow was measured in 35 patients with organic dementia (Alzheimer's disease, n = 13, vascular dementia, n = 17, frontotemporal dementia, n = 5) and orthostatic hypotension. Measurements were performed during supine rest and during head-up tilt (60 degrees). Despite marked blood pressure falls, few patients had symptoms of orthostatic hypotension. All three dementia groups h
