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
Disturbances on utilities, such as steam and cooling water, often cause large economic losses at industrial sites. Utilities are often shared between production areas, and a disturbance on a utility is therefore likely to affect a large part of the production site. In addition, production areas are often coupled by the product at the site. Obtaining a dynamic model of a site, with respect to utili
