An iterative receiver for Multiple-Input Multiple-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) wireless systems is presented and tested on channel measurements from a real indoor scenario. The receiver jointly performs channel estimation and multiuser detection, with soft information iteratively provided by the singleuser decoders. Results for the performance are presented in te

The extreme soil conditions in metalliferous mine soils have a negative influence on soil biological activity. Therefore, amendments are often used to improve soil quality and activate microbial communities. In order to elucidate some of the factors controlling microbial growth and community structure after application of amendments in acid mine soils, we performed an incubation experiment with fo

This paper addresses the challenge of how to understand and handle divergent views on the need for leadership interventions between managers and subordinates. Recent popular discourses of leadership, such as the authentic leadership perspective, privileges the potential leader himself or herself as the origin of leadership. This perspective thereby neglects the view of the followers and the essent

Summary The egress strategy in high-rise buildings has traditionally been based on the sole use of stairs for evacuation. However, it is becoming more common to include evacuation elevators in the egress strategy in high-rise buildings. Traditionally, evacuation elevators have not been allowed as an evacuation route, and people have been instructed to not use elevators in case of fire. This means

Objective: contribute to the existing body of knowledge about the specific needs of first-time parents specifically for early parenthood. Method: the databases PubMed, MEDLINE, PSYCINFO, CINAHL, EMBASE, Family Studies Abstracts, and Web of Science, were searched using search terms: prenatal, antenatal, preparation, education, parents, parenthood. The meta-synthesis included 12 articles representin

This article quantifies the energy saving potential and robustness of nine energy retrofitting measures, as well as four combinations of these, for residential building stocks of three major cities in Sweden and for five scenarios of future climatic conditions, downscaled by a regional climate model (RCM). The retrofitting measures are evaluated for five temporal resolutions of hourly, daily, mont

Taking as the starting point the increasing interest for utilizing public procurement as a means to stimulate innovation, this paper explores some considerations for curriculum development for teaching public procurement of innovation. A basic understanding of what is a curriculum was used as a foundation for the development of a master level course in public procurement of innovation in a univers

In this paper, we propose a new methodology for optimal memory mapping of data and instructions to Scratch-Pad Memories (SPM). In the mapping process, we optimize, as the main priority, the number of memory accesses to minimize power consumption. Minimization of external memory accesses lowers switching activity and therefore power consumption. The optimization is done by finding Pareto-points, us

The Swedish HE Ordinance requires all supervisors of doctoral students to undergo introductory training. The content, goals, learning outcomes and duration is not specified by the Ordinance and thus practices vary between institutions. In 2009/2010, a new study program for doctoral supervisors was launched at Lund University. The program was designed to:- provide research-based support for doctora

The traditional sheet metal forming process, including cast steel die tool and conventional work materials, is fairly well established and analysed. Developments of new alternative materials make great demands upon new forming processes and manufacturing methods. A general goal for the manufacturing industries is to reduce the weight of metal parts, reduce batch sizes and reduce the lead-time of n

The legal empowerment approach is a recent attempt to be specific about the role of institutions for the future eradication of poverty. This is a broad concept that includes not only the national formal judicial system in a country, but all formal and informal institutional structures providing the rules of the game of human interaction in any given society. It has invited a lot of debate as to wh
