När man möter en mamma eller pappa berättar de kanske om sitt barn. Men är barnen deras? I många andra sammanhang talas det om våra barn: skolan, sjukvården, föreningar gör också anspråk på att äga barnen. Världen kring handikappade barn sätter förhållandet på sin spets: där finns en myriad av yrken och institutioner, som hävdar att de både vet mer och vet bäst. Experternas kunskaper är eftersökt

A predictive PI (proportional-integral) controller with dead-time compensation is described. Its advantage compared with previous dead-time compensating controllers is that although it also contains five parameters, only three are adjusted by the operator, namely, the gain, the integral time and the dead time. The controller is also suited for processes with varying dead times. Conceptually, the n

The common-mode (CM) signal in wireline transmission systems has proven to provide valuable information exploited for mitigating narrowband noise at the receive side. We focus on the case of broadband noise. Treating the CM signal as an additional receive signal, we investigate the capacity of the copper cable channel for different levels of coordination among the users. We introduce a channel mod

It is easy to demonstrate the naivety of many people preparing messages for intelligent beings on other planets using pictures. On the other hand, constructivism, which supposes all our perception to rely on social constructs, has long been shown to be untenable, notably by Gibson, who instead suggested that some general ecological principles have to be taken into account. In a parallel fashion, I

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

It is well known that WLAN based on the IEEE 802.11 standard suffers from interference and scalability problems due to a limited number of non-overlapping channels. In order to mitigate the interference problem, channel assignment algorithms have been a popular research topic in recent years. It has been shown that such algorithms can greatly reduce the interference among wireless access points. H

The purpose of this thesis is to develop knowledge about young individuals’ reasoning and how they justify their standpoints concerning trustworthiness and decision-making in issues connected to health where available information is contradictory or uncertain. This purpose has been addressed in three different steps. In the first step almost 300 students in Swedish upper secondary school answered

One way of making sense of what is happening in international law today is to read it as a political theology; and as such a continuation of secularized Christian theological institutions. This paper is a reading of jus ad bellum (and just war tradition), jus in bello, and jus post bellum as an eschatology of international law. In order to illustrate my argument I will use the invasion and subsequ
