Migration is commonly associated with large scale movements of people, from one country to another, both in terms of refugee displacement and voluntary migration. The internal movement within countries is however less studied despite the fact that this is an important indicator for imbalance and also crucial for planning the future for the country. In Iraq, a major reason for migration has been se
This study attempts to develop a method for the simulation of surface flow paths on a digital elevation model (DEM). The objective is to use a facet-based algorithm to estimate the surface flow paths on a raster DEM. A grid DEM was used to create a triangular facet network (TFN) over which the surface flow paths were determined. Since each facet in the network has a constant slope and aspect, the
Processed food and eating out of the home are increasing phenomena, which presents new business opportunities for food manufacturers. However, the new food products require increased quality and safety, and thereby a more controlled distribution. The overall purpose of the research presented in this article is to describe the food supply chain from a critical context point of view in order to high
The estimation of three-dimensional position information from two-dimensional images in computer vision systems can be formulated as a state estimation problem for a nonlinear perspective dynamic system. The multi-output state estimation problem has been treated by several authors using methods for nonlinear observer design. This paper shows that a perspective system can be transformed to two obse
BACKGROUND/OBJECTIVES: Evidence from prospective studies is consistent in showing an inverse association between dietary fibre intake and risk of ischaemic heart disease (IHD), but whether dietary fibre from various food sources differ in their effect on IHD risk is less clear. The objective of this study was to assess the associations of total and food sources of dietary fibre with IHD mortality
This paper presents the performance of the ATLAS muon reconstruction during the LHC run with pp collisions at root s = 7-8 TeV in 2011-2012, focusing mainly on data collected in 2012. Measurements of the reconstruction efficiency and of the momentum scale and resolution, based on large reference samples of J/psi -> mu mu, Z -> mu mu and gamma -> mu mu decays, are presented and compared to Monte Ca
This thesis concerns ego-motion and pose estimation of a single camera under the assumptions of planar motion and constant internal camera parameters. Planar motion is common for cameras mounted onto mobile robots, particularly in indoor scenarios, as they remain at a constant height above the ground plane. In Paper A, a parametrisation of the camera motion and pose is presented, along with an ite
This study describes for the first time the expression levels of genes encoding membrane transporters and drug-metabolizing enzymes in the lungs of ex-smoking patients with chronic obstructive pulmonary disease (COPD). Membrane transporters and drug-metabolizing enzymes are key determinants of drug uptake, metabolism, and elimination for systemically administered as well as inhaled drugs, with con
Purpose: To investigate the characteristics and change in use among very old Swedish users and non-users of assistive devices (ADs) for mobility and personal care, over a six-year period, and to investigate factors predicting AD use over a six-year period. Method: Descriptive statistics and logistic regression were used to analyse quantitative data from a subsample from the Swedish part of the
Is the real problem in finding the relative orientation of two viewpoints the correspondence problem? We argue that this is only one difficulty. Even with known correspondences, popular methods like the eight point algorithm and minimal solvers may break down due to planar scenes or small relative motions. In this paper, we derive a simple, brute-force algorithm which is both robust to outliers an
This paper is concerned with model fitting in the presence of noise and outliers. Previously it has been shown that the number of outliers can be minimized with polynomial complexity in the number of measurements. This paper improves on these results in two ways. First, it is shown that for a large class of problems, the statistically more desirable truncated L-2-norm can be optimized with the sam
Charred seed conglomerates of Linum usitatissimum (flax) and Camelina sativa (gold of pleasure) were found at UppAyenkra 2:25, a Roman Iron Age site in SkAyenne, southern Sweden. The conglomerates showed no mixing with each other, as they were almost pure flax and gold of pleasure respectively. Together with other archaeobotanical data from the site, they provide new evidence on the use, processin
In order to assess the influence of severe hypoglycemia on local cerebral blood flow (1-CBF) artificially ventilated rats, maintained on 70% N2O, were injected with insulin to provide either an EEG pattern of slow-wave polyspikes, or cessation of spontaneous EEG activity for 5, 15 or 30 min ("coma"). In other animals, glucose was injected at the end of a 30 min period of "coma" and 1-CBF was measu
This thesis takes off in framing theory and the theory of securitization to investigate the Yemeni government’s framing of its oppositional groups the Houthis and the Southern Movement. My purpose is three-folded: 1) to describe the conflicts between the Yemeni government and these two oppositional groups within their local and global context; 2) to illustrate how the Yemeni government is using th
It is the purpose of this paper to compare the securitization processes of the A(H1N1) virus, more commonly known as the swine flu, in Sweden and Germany. Based on the recognition that these countries, for all intents and purposes, are very similar it is the aim of this essay to understand how the results of their respective securitization processes could be so widely different. This study is cond
Årtionden efter att internationella klimatförhandlingar inleddes tampas världen fortfarande med den grundläggande frågeställningen hur klimatåtgärder skall mobiliseras. Samtidigt stiger kostnaderna till följd av vår passivitet. Det har visat sig nästintill omöjligt för det internationella samfundet att göra upp om ett gemensamt, bindande regelverk för klimatpåverkan. Även på regional och lokal nivSeveral decades after the initiation of international climate change negotiations, the world still struggles with the issue of how to mobilize climate action. In the meantime, the costs of inaction rise to unprecedented heights. It has proven more than difficult – even impossible for the international society to agree upon a binding common framework, and also on regional and local levels are regul
The purpose of this study was to examine how different Swedish municipalities proceeded to transform the sanction youth service to practice in the context of the laws, the preparatory works and the guidelines which concern the sanction. Semi-structured interviews were used to acquire the material along with a so-called interview guide, which consisted of a list of fairly specific themes that were
Article 102 TFEU prohibits any abuse by one or more undertakings in a dominant position. A dominant undertaking offering exclusivity rebates falls under the prohibition laid down in Article 102 TFEU. The treatment of exclusivity rebates in case law has been a controversy, the first cases held a strict approach towards exclusivity rebates and established that exclusivity rebates are to be assessed
A global trend of decentralisation has been present in the last decades. Since the 1980s, most countries have transferred power and resources from the centre to subnational levels of government. This trend has also been present in the developing world where it has been encouraged by international organisations as a way of promoting citizen participation and democracy. The purpose of this thesis is
Thesis reflects on the notion of photojournalism, media and communication processes in the era of Internet and redeveloped global cultural exchange opportunities. Subject of authenticity in the news coverage and digital manipulation of the image contents – used under various conditions depending on intention – become the current social problem that it’s forced routinely and which demands a broader
