We have studied the interaction of light with an array of vertically oriented III-V semiconductor nanowires both theoretically and experimentally. For the theoretical studies, electromagnetic modeling has been employed. This modeling shows that with proper tuning of the nanowire diameter, the absorption per volume semiconductor material can be 20 times higher in the nanowires than in a correspondi

In 2001, a paper published in Nature by Andrews et al postulated the use of six co-located antennas, namely three electric and three magnetic dipoles, to achieve up to a six-fold capacity increase in wireless channels, relative to that of a single antenna. In other words, six degrees of freedom (DOFs) can be supported in a wireless channel with co-located six-port transmit and receive antenna arra
The SVARNE project investigates how an expert system may be used when dealing with occurrences of violence within the care of people with cognitive impairments. The method used is potentially applicable in many other areas where the expert knowledge is ma
This paper addresses issues of population policy and stratified reproduction in Singapore. When Singapore gained its independence in 1965 the government initiated an ambitious modernization program. The economy was restructured, farmland and villages were torn down to give way to high‐rise housing estates and infrastructure, and the education system was reformed. Population management has been (an
This paper presents and discusses results from the research project LETS 2050 that studies the governance challenges of a transition to a low-carbon transport and energy system in Sweden by 2050 (www.lets2050.se ). A key starting point of the project was that a low carbon transition is technically possible and economically feasible, while the main challenge is political. At the moment there is an
