This manuscript presents an reconfigurable architecture, suitable to process time synchronization for multiple OFDM standards. The proposed architecture is based on a coarse-grained reconfigurable cell array, and the different radio standards under analysis are IEEE 802.11n, 3GPP Long Term Evolution and Digital Video Broadcast for cellular devices. With the use of a 2-by-2 cell array, composed of

In radiological diagnostics and therapy, it is important that practitioners, referrers, (i.e. radiologists, radiation oncologists and others in health-care) are aware of how much radiation a patient may receive from the various procedures used and associated health risk. The profession has a duty to inform patients or their representatives of the advantages and disadvantages of specific investigatIn radiological diagnostics and therapy, it is important that practitioners, referrers, (i.e. radiologists, radiation oncologists and others in healthcare) are aware of how much radiation a patient may receive from the various procedures used and associated health risk.

ABSTRACT The existence of sound symbolic and mimetic words in the Japanese language is well known. Although the most common appearance of these sound symbolic words occurs in Japanese comics they do exist in many other forms of media, ranging from television shows to everyday conversation. These words, a very good tool for the native Japanese speaker to convey intimate meanings and sensations, po

The immune system has evolved regulatory mechanisms in order to balance the effects of deleterious immune responses. Such immunological tolerance may be specifically acquired by lymphocytes, although different cells of the immune system participate in the induction and maintenance of tolerance. This thesis work is based on investigations of different tolerance mechanisms induced in CD4+ T lymphocy

The concept using inside information has its origin in Directive 2003/6/EC on insider dealing and market manipulation, Market Abuse Directive. The Market Abuse Directive requires Member States to prohibit and penalize market abuse. The expression using inside information is found in the prohibition on insider dealing in Article 2.1 in the Directive. This article requires Member States to prohibit Begreppet utnyttjande av insiderinformation har sitt ursprung i direktiv 2003/6/EG om marknadsmissbruk, MmD. MmD ålägger medlemsstaterna att förbjuda och beivra marknadsmissbruk. Uttrycket utnyttjande av insiderinformation återfinns i förbudet mot insiderhandel, som i huvudsak regleras i artikel 2.1 i MmD. Artikel 2.1 föreskriver att medlemsstaterna ska förbjuda en person som förfogar över insider

The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. More sophisticated engine instrumentation with additional degrees of freedom has been added to the engine de

An increasing number of robots have been used for the finishing of castings during recent years. This is mainly due to developments to overcome problems that restricted their use during the past decade. The major difficulties have been the need to control reaction forces during metal removing by grinding operations and the lack of tools designed specially for robots. The elimination of these two p

The underground is a vast region, which is, too a large extent, unused by man. It has a large potential as a storage facility due to its vastness and availability. This thesis, which consists of eleven papers and reports, deals with nuclear waste repositories in solid rock and with aquifer thermal energy storage systems. All these storage systems induce multidimensional, time-variable thermo-hydr

This thesis examines how freshwater crayfish affect community interactions in benthic food webs. I have mainly studied the influence of the introduced signal crayfish (Pacifastacus leniusculus) on littoral communities, but also the influence of the native noble crayfish (Astacus astacus). Overall, the results show that both crayfish species are omnivores having strong direct and indirect effects o
