As interest in social vulnerability to hazards grows, more indices are formulated for identifying and mapping population groups that may experience differential consequences from natural hazards. However, less attention has been given to the underlying choices researchers make when creating these indices. With the aim to contribute to understanding the issues surrounding social vulnerability indic
In this thesis methods for finding state space representation parameters for low inductance DC-motors are found and evaluated. Theory previously tested in simulations is verified experimentally and improved upon for both linear behaviour when the motor is controlled with a DC-source as well as nonlinear behaviour when controlled with pulse width modulation (PWM). For the linear behaviour a linear
This master thesis project has developed a method for a six-legged robot to traverse uneven terrains. From a previous project, the robot already possessed basic locomotion which had to be extensively redesigned. Several new subsystems have been introduced, such as a continuous balancing system, a system estimating the slope of the ground the robot is walking on, and method for detecting when the r
Interactions between T-cells and other body cells is an essential part of the immune system. It involves the binding between surface receptors of the two cells. Specifically, T-cell receptors (TCRs) bind onto pMHC (peptide-loaded major histocompatibility complex) molecules on the partnering cell surface. This way, a cell signal from the TCR to the nucleus can be initiated. Depending on the "m
Historiskt sett har transportören, med undantag för force majeure och krigshandlingar, varit strikt ansvarig för all skada på det transporterade godset. Detta kom att förändrades under slutet av 1800-talet och början av 1900-talet när transportörerna började begränsa sina ansvarsgrunder med klausuler i transportavtalen. Snart var transportörerna inte ansvariga för i princip någonting, vilket var pThe carrier has historically been strictly liable for all damage to the cargo carried, with the exception of acts of God and war. This changed during the late 1800’s and early 1900’s when the carriers began to limit their liabilities in the contract of carriage. They were soon not liable for very much which was problematic for the shippers, since they did not receive compensation when their goods
Uppsatsens syfte är att analysera hur genus kan göras och ogöras med fokus på kvinnor i relation med alkoholiserade män samt hur det avspeglar och påverkar marginalisering i det litauiska samhället. Undersökningen är avgränsad till en tidsperiod oktober 2016 och oktober 2018 och fokuserar på Litauen. I syfte att hitta relevanta artiklar och kartlägga kontexten i vilken dessa är producerade används
In Reinforcement learning the updating of the value functions determines the information spreading across the state/state-action space which condenses the valuebased control policy. It is important to have an information propagation across the value domain in a manner that is effective. Two common ways to update the value function is Monte-Carlo updating and temporal difference updating. They are
This study aims to explore the impact of paid work in the Ethiopian export-oriented garment industry on women’s empowerment, as perceived by the women themselves. The study first explores the reasons for why and how women pursue paid work in the industry. It further examines the ways in which paid work might affect women’s intra-household decision-making. By focusing on the experiences among vario
Världens sötvattensystemen är sårbara och har upplevt betydande miljöförändringar. Utöver direkt mänsklig påverkan, innebär klimatförändringar ytterligare påfrestningar på våra färskvattenresurser. I denna studie undersöks hur klimatförändringar har påverkat tidsperioden av istäckning i svenska sjöar och vattendrag. Observationer från över 750 sjöar och vattendrag i Sverige har analyserats, med viThe worlds freshwater systems are vulnerable and have experienced significant environmental changes. In addition to direct anthropogenic impacts, climate change poses yet another source of pressure on the freshwater resources. This study investigates climate change impacts on ice cover duration in Swedish lakes and rivers. In situ observations from over 750 lakes and rivers in Sweden were analyzed
Insulating glass unit (IGU) is separated double or triple glass panes with closed cavities in between, usually filled with argon to reduce the heat transfer. When a construction like this is exposed to temperature variations the volume of the gas will change and pressure changes will occur. The glass panes will bulge which will give displacements and stresses in the glass panes. For large dimensio
The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. The PA core consists of a cross-coupled pair of NMOS transistors with an NMOS current source. This st
In this thesis, we study the Jarrow and Yildirim framework for inflation modeling and provide a new specification based on spread modeling which allows to calibrate the model to Zero-Coupons and Year-on-Year options jointly with convexity adjustments. We use this model to provide closedform formulas for options volatilities, convexity adjustments and Year-on-Year swaptions prices. Calibration resu
The present study sought to investigate whether implicit gender attitudes and ambivalent sexism predict the appreciation of sexist humour. A computer-timed Brief Implicit Association Test (BIAT) was used to measure participants’ (N = 83) implicit gender attitudes. Explicit gender attitudes were measured with a Swedish version of the Ambivalent Sexism Inventory (ASI). Four short stand-up comedic vi
Political trust in the EU has declined substantially in recent year and the growing divide between the Eurozone and the other member countries are at the heart of the scholarly debate. As a result, there is a growing body of literature on the determinants of political trust and public opinions in the EU. Existing research propose and test several explanations for the foundations of political trust
Previous research in the field of Environmental Federalism has not reached an agreement on whether fiscal decentralization leads to an increase in environmental pollution, i.e. a race to the bottom, or decrease in it, i.e. a a race to the top. Farzanegan and Mennel (2012) point out that this discrepancy may be due to institutions. Employing the OLS estimator, they find that fiscal decentralization
Concentration of wealth has received considerable attention in recent years, and research shows that it is not only a modern day phenomenon. This thesis contributes to the ongoing debate by presenting wealth inequality estimates for rural Finland from 1750 to 1900 in three regions – East, Southwest and North. The current study uses a rich dataset of probate inventories containing over 18 000 obser
In Germany, prisoners have a constitutional right to rehabilitation (“resocialization”). In the Lebach judgment of 1973, a landmark ruling that served as the basis for the 1976 Prison Act (Strafvollzugsgesetz [StVollzG]), rehabilitation was seen by the German Federal Constitutional Court as part of the guaranteed rights of prisoners to retain their human dignity (Dünkel & van Zyl Smit, 2007, p
Polymers of N-substituted glycine (NSG) or as they are also called, peptoids, have shown potential in biomedical applications due to proteolytic resistance, among other interesting properties. In this thesis project, two synthetic routes have been performed and evaluated to achieve a better understanding of large-scale syntheses of peptoids as a bioinert coating for nanoparticles. The primary fo
