The project is carried out in the municipality of Svalöv who are currently building a fiber netwo
This dissertation is a thematic reading of 1,574 items from four Japanese and three Taiwanese major daily newspapers published in the 2000-2008 period. It argues that the concepts of repetition and representation play key structural and narrative roles in the sources and outlines how these concepts operate and how they interrelate on a content level as well as on a level of larger media frameworks
Purpose of this research The ability to quickly respond presupposes logistics systems designed to be responsive; supply chains must prepare to act if specific circumstances occur. By investigating ‘preparedness’ in a defence logistics context, the overall research objectives are to define ‘preparedness’ and to advance defence logistics as an academic research area. Design/methodology/approach We
Studying gene-environment interactions requires that the amount and quality of the lifestyle data is comparable to what is available for the corresponding genomic data. Sweden has several crucial prerequisites for comprehensive longitudinal biomedical research, such as the personal identity number, the universally available national health care system, continuously updated population and health re
We jointly optimize Discontinuous Reception (DRX) cycle length and LTE scheduling to minimize mobile devices' energy usage for video delivery, utilising the now well-established potential to predict future channel conditions in cellular networks. Employing in-network caching, we set a strict buffer constraint which provides zero buffer underflow to improve Quality of Experience. Our study provides
It has been known that load unaware channel selection in 802.11 networks results in high level interference, and can significantly reduce the network throughput. In current implementation, the only way to determine the traffic load on a channel is to measure that channel for a certain duration of time. Therefore, in order to find the best channel with the minimum load all channels have to be measu
Dynamic Adaptive Streaming over HTTP (DASH)constitutes a large fraction of traffic in the mobile Internet.Mobile devices often use video delivery over Wi-Fi, which is asignificant energy drain. Dynamic Power Saving Mode (DPSM)is one of the most widely-used approaches for Wi-Fi devices tosave power and shorten packet delay. However, DPSM uses afixed timeout before a device goes to sleep, leading to
We propose an end-to-end approach to describe the energy usage of video delivery within a content delivery framework, and use this to investigate the energy usage behavior of two popular coding schemes, namely, H.264/AVC and H.265/HEVC. Our study based on the proposed model is backed up by measurements of encoding and decoding energy usage of a sample video and shows that, from an end-to-end persp
This paper presents measurement results for a low supply voltage 28 GHz beam steering PLL, designed in a SiGe bipolar process with fT = 200 GHz. The PLL, designed around a QVCO, is intended for a beam steering 81-86 GHz E-band transmitter. Linear phase control is implemented by variable current injection into a Gilbert type phase detector, with a measured nominal phase control sensitivity of 2.5˚This letter presents measurement results for a low supply voltage 28 GHz beam steering PLL, designed in a SiGe bipolar process with fT=200 GHz.

Avhandllingen försöker besvara tre frågor, bThe purpose of the thesis is to further understand key conceptual and operational challenges that international aid donors, and public and private institutions, face while designing and implementing alternative forms of social housing finance which aim to be inclusive for the urban poor. Based on an in-depth study of the work of the Foundation for the Promotion of Local Development (PRODEL) in thr
Popular Abstract in Swedish Detta är en studie om Willy Brandt och Berlinfrågan. Berlinfrågan kom att symbolisera en stor del av Brandts politiska gärning och med den som utgångspunkt belyses och analyseras hans politiska livsverk. Med hjälp av en semantisk metod undersöker författaren hur Brandts politiska språk är uppbyggt och redovisar hur hans argumentation ser ut. Tyngdpunkten i studien är enWilly Brandt is one of the most important charismatic leaders of the postwar era and his Ostpolitik is considered his great political achievement. The Berlin Question can be said to symbolize his political activities. Therefore, by concentrating on this issue I can explore and analyse his political thinking as a whole. My basic assumption in this dissertation is that a politician tends to stick to
Viral vector-mediated gene transfer utilizing adeno-associated viral vectors has recently entered clinical testing as a novel tool for delivery of therapeutic agents to the brain. Clinical trials in Parkinson's disease using adeno-associated viral vector-based gene therapy have shown the safety of the approach. Further efforts in this area will show if gene-based approaches can rival the therapeut
In Huntington's disease (HD), the mutant huntingtin protein is ubiquitously expressed. The disease was considered to be limited to the basal ganglia, but recent studies have suggested a more widespread pathology involving hypothalamic dysfunction. Here we tested the hypothesis that expression of mutant huntingtin in the hypothalamus causes metabolic abnormalities. First, we showed that bacterial a
PURPOSE: To evaluate accuracy and noise properties of a novel time-resolved, three-dimensional, three-directional phase contrast sequence with variable velocity encoding (denoted 4D-vPC) on a 3 Tesla MR system, and to investigate potential benefits and limitations of variable velocity encoding with respect to depicting blood flow patterns. MATERIALS AND METHODS: A 4D PC-MRI sequence was modified t
Huntington disease (HD) is a fatal neurodegenerative disorder caused by expansion of a CAG repeat in the HD gene. Degeneration concentrating in the basal ganglia has been thought to account for the characteristic psychiatric symptoms, cognitive decline and motor dysfunction. However, the homeostatic control of emotions and metabolism are disturbed early in HD, and focused studies have identified a
Dopamine replacement for Parkinson's disease (PD) have seen three major iterations of improvements since the introduction of l-3,4-dihydroxyphenylalanine (l-DOPA) pharmacotherapy: dopamine receptor agonists, ex vivo gene transfer for cell transplantation and most recently in vivo gene therapy. In this chapter, we describe the principles behind viral vector-mediated enzyme replacement in PD. We foc
Popular Abstract in Swedish Antonymer är motsatsord, t.ex. stor-liten, kort-lång, och varm-kall. Den här avhandlingen handlar om antonymer och om vilken typ av lexikal information som man kan lagra i ett elektroniskt lexikon (Svenskt Ordnät) samt hur man kan få fram lexikal information ur stora textmassor med datorns hjälp. Baserat på hur vanliga ord är kan man beräkna hur ofta man kan förvänta siHow are antonym relations acquired? What types of lexical information can be extracted from corpora and how? How can this information be encoded in a lexicon? The work in this book was developed within the framework of WordNet. A further elaborated lexical model is suggested, as well as methods for implementing it. The first part of the book is a study of adjectives co-occurring with adjectives. E
This thesis consists of five papers on different aspects of parametervariation in some common exchange rate models.The first paper investigates the stability in the real exchange rate, witch is equivalent to purchasing power parity (PPP). In recent empirical literature on purchasing power parity, the focus has been on the stationarity of real exchange rates, instead of strict constancy. Earlier st
This thesis is about the theology of the leader of Anglican evangelicalism, John Stott. Throughout this study of evangelical identity, the relationship between the objective belief and the subjective experience is a main thread. An attempt at definition of the Anglican evangelicalism: Theologically, evangelicalism means that the bibliology and the doctrine of salvation have been in the foreground
