PURPOSE: To provide estimates of the diffusional kurtosis in the healthy brain in anatomically defined areas and list these along previously reported values in pathologies. MATERIALS AND METHODS: Thirty-six volunteers (mean age = 33.1 years; range, 19-64 years) underwent diffusional kurtosis imaging. Mean kurtosis (MK), radial kurtosis (RK), mean diffusivity (MD), radial diffusivity (RD), and frac
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
Popular Abstract in Swedish Allt fler ungdomar i vårt land, liksom i många andra länder, lever i vardagen med mer än en kultur. En femtedel av eleverna i den svenska skolan är antingen själva födda i ett annat land eller har minst en förälder med utländsk bakgrund. För många av dessa barn och ungdomar har därför inte samhällets dominerande kultur funnits med från början av deras liv. Bekantskapen The present study is based on interviews with 22 youth and young adults. The perspective is phenomenological, since my aim has been to analyse and describe the everyday world as it presents itself to these young people. A process begins in the encounter with the majority culture and the emphasis is on how they think about events and experiences along the road to a more complex life-world. The proc
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
PURPOSE: To investigate if resting-state functional MRI (fMRI) reliably can serve as a complement to task-based fMRI for presurgical mapping of the sensorimotor cortex. MATERIALS AND METHODS: Functional data were obtained in 10 healthy volunteers using a 3 Tesla MRI system. Each subject performed five bilateral finger tapping experiments interleaved with five resting-state experiments. Following p
The genus Helicobacter has expanded at a rapid pace and no fewer than 31 species have been named since the proposal of the genus in 1989. Of these 31 species, 22 are principally associated with extragastric niches and there is increasing interest in the role of these taxa in diseases of humans and animals. Substantial evidence attests to certain species playing a role in the pathogenesis of enteri
This work concerns reduction of the peak flow rate of a district heating grid,a key system property which is bounded by pipe dimensions and pumpingcapacity. The peak flow rate constrains the number of additional consumersthat can be connected, and may be a limiting factor in reducing supplytemperatures when transitioning to the 4th generation of district heating.We evaluate a full year of operatio
We present a tool for modeling conflict situations that enables simulation and testing of situation awareness in shared autonomy, in this case in an autonomous driving scenario. The flexibility of the tool allows definition of new conflict situations, integration with various control and conflict detection systems, as well as customization of Takeover Request (TOR) signals and different means of c
Traditional control systems face challenges in managing high data loads and computing power, prompting the evolution of Cloud Control Systems (CCS)-a fusion of Networked Control Systems (NCS) and cloud computing. Despite offering manifold advantages, CCS encounters hurdles in navigating the dynamic cloud environment characterized by fluctuating workloads, rendering static frequency settings ineffi
Moths (Lepidoptera) are some of the most economically important pests in human agriculture. Conventional insecticides used for management promote insecticide resistance in addition to cause human- and environmental harm. This emphasises an inescapable need for sustainable alternatives and integrated practices. Moths rely on species-specific female-emitted sex pheromones for communication and repro
This paper examines the local exponential stability (LES) of trajectories for nonlinear systems on Riemannian manifolds. We present necessary and sufficient conditions for LES of a trajectory on a Riemannian manifold by analyzing the complete lift of the system along the given trajectory. These conditions are coordinate-free which reveal fundamental relationships between exponential stability and
In this paper we consider calibration of hydraulic models for district heating networks based on operational data. We extend previous theoretical work on the topic to handle real-world complications, namely unknown valve characteristics and hysteresis. We generate two datasets in the Smart Water Infrastructure Laboratory in Aalborg, Denmark, on which we evaluate the proposed procedure. In the firs
We consider control of multiple stable first-order systems which have a control coupling described by an M-matrix. These agents are subject to incremental sector-bounded nonlinearities. We show that such plants can be globally asymptotically stabilized to a unique equilibrium using fully decentralized proportional integral anti-windup-equipped controllers subject to local tuning rules. In addition
Context: Evidence-based software engineering (EBSE) aims to improve research utilization in practice. It relies on systematic methods to identify, appraise, and synthesize existing research findings to answer questions of interest for practice. However, the lack of practitioners’ involvement in these studies’ design, execution, and reporting indicates a lack of appreciation for the need for knowle
This thesis work has focused on the platinum-tin surface, especially how it behaves when exposed to gases like oxygen and carbon monoxide. Platinum-tin is used as a catalyst for a range of reactions, including the oxidation of carbon monoxide at mild conditions, which is important for gas purification in fuel cells. The platinum-tin alloy has properties useful for the reactions it catalyses, but i
Innan ett aktiebolag går i konkurs är det inte ovanligt att en större överföring görs, exempelvis till aktieägare. Aktiebolagslagen innehåller regler som kan användas mot bolag som företar illojala transaktioner mot borgenärer. En återbäringstalan av olovlig värdeöverföring är ofta komplex och ekonomiskt tung då omfattande utredningar av bolaget krävs. Konkurslagens återvinningsregler, framföralltBefore a public company goes bankrupt, it is not uncommon that a large transfer is made, for example, to the shareholders. The Limited Company Act i.a. Company Act contains rules that can be used against companies who undertake unlawful transactions from their creditors. A repayment claim of an unlawful transfer is often complex and economically heavy, because major investigations of the company n
Nödvärnsrätten regleras i 24 Kap. 1 § BrB. Den typen som är relevant för uppsatsen är nödvärn i förhållande till ”ett påbörjat eller överhängande brottsligt angrepp på person eller egendom,” vilken regleras i punk 1. Nödvärn är en objektiv ansvarsfrihetsgrund som kräver att brukaren gör avvägningar mellan angrepp och försvar för att handlingen inte skall anses som uppenbart oförsvarlig. Detta krävThe right to self-defence is regulated in chapter 24 § 1 of the swedish Penal Code. The type which is relevant to this paper is the one concerned with current or imminent criminal attack on a person or property which is found in the first point of the paragraph. Self-defence is an objective ground for discharge of liability. For the act of self-defence to not be considered obviously unjustified th
Globally, the production and consumption of plastic has increased exponentially. As plastic items are produced using fossil fuels, the plastic industry is intrinsically tied to the petrochemical industry. One unique case of this dilemma lies in the petrochemical industry’s role in plastic production in Taiwan. Despite its reputation for recycling, Taiwan is satiated with ineffective sustainability
Värdering av tillgångar har betydelse i flera avseenden. Denna uppsats har till syfte att utreda hur värderingen går till vid tvångsmässiga situationer och även att identifiera vilka kriterier som påverkar värderingsprocessen i olika tvångsmässiga värderingssituationer. Jag har valt att granska fem olika tvångsmässiga situationer, nämligen konkurs, företagsrekonstruktion, utmätning, expropriation Valuation of assets is important in several aspects. This essay has aimed to investigate how the valuation is done in compulsory situations and to identify the criteria’s that affect the valuation process in compulsory situations. I have chosen to examine five different compulsory situations, namely bankruptcy, corporate reorganization, foreclosure, expropriation and the preparation of a control b
