Popular Abstract in Swedish Surfplattor och mobiltelefoner med prestanda i klass med den hos stationära datorer för bara några år sedan är resultatet av den kontinuerliga hårdsatsning som i över 50 års tid stadigt lyckats göra den minsta elektronikkomponenten, transistorn, mindre, snabbare och mer strömsnål. Under senare år har det dock blivit svårare att förbättra prestandan enbart genom att minsThe background of this thesis is related to the steadily increasing demand of higher bandwidth and lower power consumption for transmitting data. The work aims at demonstrating how new types of structures, at the nanoscale, combined with what is referred to as exotic materials, can help benefit in electronics by lowering the consumed power, possibly by an order of magnitude, compared to the indust

The purpose of this study is to investigate the firm value effect of the relative voting power between the minority blockholders and the largest shareholder in firms, and the excess voting rights relative to capital rights for minority blockholders. The Holdings database was used to collect detailed ownership data on a sample of 266 listed Swedish firms corresponding to 1 781 firm-year while finan

In this study a coarse-grained model of intrinsically disordered proteins (IDPs) is evaluated to determine whether the model is suitable to use for analyzing the structure and dynamics of IDPs. IDPs are proteins that lack a stable tertiary structure which gives them a flexible structure. The aim with this study is to find a model that is appropriate to use for analyzing dynamics events of IDPs. To

Menstruation is a normal body function and a sign of reproductive health. Although it is a fundamental human right for girls and women to have the ability to properly manage their menstruation, it is a long-neglected issue in low-income countries. Pilot studies have provided optimism for the menstrual cup’s potential to improve the quality of life for Ugandan girls and women. Several actors are in

In recent years, many scholars have observed increasing polarization in the distribution of labor market risk, as well as social and employment rights. This phenomenon is often referred to as labor market dualization, a process deepening the divide between privileged insiders and less fortunate outsiders. Some authors have begun to search for a possible insider-outsider divide in policy preference

The permanent magnet synchronous motor, PMSM, is an efficient electrical motor that has seen a greater prevalence in the automotive industry from the increasing demand for electrical vehicles. Managing the temperature of the permanent magnet rotor is important to optimize motor utilization and avoid hardware failures. Direct temperature measurements of the moving rotor with a sensor are, however,

China, as a huge and promising market, has always been largely exposed to and influenced by the Japanese and Korean idol industries. With various attempts trying to adopt the transnational experienced idol production within the challenging Chinese context, numerous reality television talent shows had been introduced in the past few years. After the very first boy group talent show, Idol Producer (

How can a physical working environment be created that can prevent psychological problems such as depression and burnout and thus have a lasting effect on us mentally, socially and physically? Which aspects of human nature have to be taken into account? Holistically, findings from different fields are carried together to meet the needs of the individual but also the requirements of a modern perfo

Employment restrictions have been experienced by many people with epilepsy. In many cases, the restrictions are unjustified and based on stigma or a stereotypical image of the person with epilepsy. Unjustifiable restrictions are a form of discrimination and lead to unemployment and underemployment. Unfortunately, much of the research in this area has been difficult to interpret because of differen

The concept of a fair and optimal allocation was recently introduced by Sun and Yang [Sun, N., Yang, Z., 2003. A general strategy proof fair allocation mechanism. Economics Letters 81, 73-79]. This note states some basic properties of fair and optimal allocations and provides a simple algorithm for identifying them. (C) 2007 Elsevier B.V. All fights reserved.

Nuclear Quadrupole Resonance (NQR) is a method of de- tection and unique characterization of compounds containing quadrupolar nuclei, commonly found in many forms of ex- plosives, narcotics, and medicines. Typically, multi-pulse sequences are used to acquire the NQR signal, allowing the resulting signal to be well modeled as a sum of exponentially damped sinusoidal echoes. In this paper, we improv

Image monitors and viewing boxes have a crucial role in the diagnostic process. Modern radiology uses different modalities to produce digital images which are to be viewed in different parts of the radiology department and throughout the hospital, sometimes simultaneously, via the Picture Archiving and Communications System (PACS). Therefore, the quality of the image monitors is of great importanc

In this paper we provide a far-reaching generalization of the existent results about invariant subspaces of the differentiation operator D=∂t on C^{\infty}(0,1) and the Volterra operator Vf(t)=∫f(s)ds, on L^{2}(0,1). We use an abstract approach to study invariant subspaces of pairs D,V with DV=I, where V is compact and quasi-nilpotent and D is unbounded densely defined and closed on the same Hilbe

Modern antenna design for communication systems revolves around two extremes: devices, where only a small region is dedicated to antenna design, and base stations, where design space is not shared with other components. Both imply different restrictions on what performance is realizable. In this paper properties of both ends of the spectrum in terms of MIMO performance is investigated. For small a

Background: The development of social assistive robots is an approach with the intention of preventing and detecting falls among seniors. There is a need for a relatively low-cost mobile robot with an arm and a gripper which is small enough to navigate through private homes. Material and methods: User requirements of a social assistive robot were collected using workshops, a questionnaire and inte
