The next challenge for MIMO radio channel models is to simulate the time-variant nature of the channel correctly. Cluster-based MIMO channel models are well suited for this problem, however they currently lack an accurate parameterization of the time-variant cluster parameters. In this paper we identify and track clusters from three differentmeasurements conducted in an indoor, a sub-urban, and a

High-speed communication using the copper network, originally installed for telephony, is one of the dominant Internet access techniques. Several variants of a technology referred to as digital subscriber line (xDSL) have been developed, standardized and installed during the last two decades. Essentially, xDSL achieves high rates by exploiting wide bands of the copper cable channel. The shorter th
Increased logistics outsourcing and importance of supply chain integration (SCI) have attracted our interest in studying how logistics service providers (LSPs) are viewed as contributors to SCI and to their clients' performance. On the basis of LSPs? roles as they emerge from SCI-performance literature and from analysis of LSP-websites on how they communicate their role(s), we discuss how this dif
Elsewhere I have argued that the notion of a normative agent-neutral reason is undermined by certain views on reasons; the existence of agent-neutral reasons can be questioned. Here I shall not repeat my doubts but rather address a way of expressing the distinction that I had not considered and which would, if correct, put an end to my worries about the soundness of this dichotomy. The idea, which
I min analys försöker jag ta reda på om kursplanen för NOR stämmer överens med principen för ”constructive alignment”. Jag har utgått från John Biggs och Catherine Tangs bok ”Teaching for Quality Learning at University” från 2007, där de redogör för vad ”constructive alignment” innebär och hur konceptet kan användas i praktiken för design av kursupplägg och undervisning. ”Constructive alignment” (
The new Department of Design Sciences was established as a result of the reorganisation of the Lund Institute of Technology, Lund University. The main ambition of this new department is to facilitate interdisciplinary scientific research and to support the development of new research areas, one of which is packaging logistics where the packaging perspective is used to evaluate and develop logistic
