Fully-synchronous measurements of a massive multi-user multiple-input multiple-output (MU-MIMO) radio propagation channel are presented. We evaluate the ability of a massive MIMO system to spatially separate users located close to each other in line-of-sight (LOS) propagation conditions. The system consists of a base-station (BS) antenna array equipped with 64 dual-polarized antenna elements (128
This work presents a literature review and a questionnaire study with 62 participants aimed at providing recommendations on the design of a set of evacuation systems for road tunnels: 1) Traffic Information Sign (TIS) - message and size of the sign (large or small), colour scheme, and use of pictograms and/or flashing lights, 2) Emergency exit portal layout - colour scheme, 3) Acoustic systems - v
The morphological matrix is an important element of the engineering design methodology and is present in many textbooks. This method originally aimed at generating an exhaustive set of solutions for a given problem, by decomposing it into subproblems, finding solutions to each subproblem, and combining them. One issue associated with the morphological matrix has been the necessity to deal with the
Målet med att införa kontinuerliga självvalda kontroller under en kurs gång är att på så vis engagera och motivera studenterna att läsa kontinuerligt redan från kursstart. De självvalda kontrollerna genomförs individuellt under kursen för att fånga upp vilka kunskaper som studenten införskaffat hitintills. Ett bra resultat på dessa självvalda kontroller innebär att studenten erhåller bonuspoäng vi
Popular Abstract in Swedish Biotisk och abiotisk stress hos mikroorganismer och växter.Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. coli, was subjected to directed evolution with NaCl as selective pressure. The resulting clones were teste
The S.T.A.R. Design Studio (Space and Terrestrial Architectural Research) studies pre-industrial habitats in i.a. Tanzania, and develops design concepts for future habitats in space in cooperation with Johnson Space Centre, Houston, Texas. In both cases our studies focus on "extreme" circumstances. Perhaps studying the conditions of a crew sealed in a capsule can better prepare us for the problems
Zabrze is a medium size town of 200 000 inhabitants in the region of Upper Silesia, Poland. The development of the town was originally based on the exploitation of heavy industries. In the past few years Zabrze has, however, moved towards more service and tourism oriented industries. As part of this journey, the city of Zabrze sees the need to improve its existing waste management system. This rep
