The global energy transition and the growing adoption of electric vehicles drives an ever-increasing demand for more efficient electrical machines. A key improvement area is understanding and reducing iron losses in machine magnetic materials, such as those caused by Pulse Width Modulation (PWM). This thesis investigates the effects of PWM on magnetic hysteresis and the resulting iron losses in Fe

De senaste 51 åren har norra Europa upplevt nio ovanligt kalla vintrar där många temperaturrekord har satts. Två av de tre senaste vintrarna, 2009/10 och 2010/11, var de kallaste på många håll i södra Sverige sedan mitten av 80-talet. Den allra kallaste vintern i södra Sverige var dock enligt SMHI (Sveriges Meteorologiska och Hydrologiska Institut) vintern 1962/63 då det i genomsnitt var cirka 2˚CThe past 51 years northern Europe has experienced nine unusually cold winters, where many temperature records have been set. Two of the three last winters, 2009/10 and 2010/11, were the coldest in many places in southern Sweden since the mid 80’s. However, the coldest winter in southern Sweden was, according to SMHI (Sveriges Meteorologiska och Hydrologiska Institut), the winter of 1962/63, when i

This paper explores the nature of migration in Egypt from a Sub-altern realist perspective. As a criticism of traditional realist theories, Sub-altern realism argues that states in the Third World are defined by their weak state structure, which in turn changes their behavior both towards other states and on the domestic arena. This paper is based on findings from a Minor Field Study that I conduc

This study will examine the practices and semiotic structures within the Jewish community in Malmö, linked to the last three years of conflict situations. In the media, Malmö has been described as a problematic city for people with a Jewish heritage, to live in. Swedish, as well as international media caught a big attention to this new conflict. In the aftermath of the articles the situation was l

The debate over Corporate Social Responsibility is present in many parts of society. The business sector’s engagement in CSR has increased rapidly during the last decades. One important question this brings out is how CSR should be governed. The debate consists in large of two views – CSR should be regulated by law or forced regulation or CSR should be managed through private and civil regulation

Algeria, alongside many other countries, was not swept up in the so called third wave of democratization. Instead, the wake of some political opening, it experienced a return to authoritarian rule. With the holding of regular elections in a multi-party system that allowed for relatively free press, traditional democratization theory would predict political reform. Arguing that this liberalized for

The paper sheds light on financial contagion within the Euro Area and Asia, and contagion from the Euro Area to Asia during two recent crises: the global financial crisis and European sovereign debt crisis. Applying the multinomial logit regression model, the paper investigates how the macro-finance variables affect the coincidence of extreme negative returns (coexceedances). In addition, I apply

The purpose of this study was to illustrate and examine how social workers professional identity shapes and maintains when they work in an arena where social work is not in focus. We used a qualitative method. Semi-structured interviews were conducted using an interview guide. We interviewed nine professional social workers who works in three different field - probation, hospital and school. Profe

Women constitute a minority among patients in forensic psychiatric care, which aims to improve the patients’ health while ensuring safety for patients, caregivers, and society. Participation in forensic psychiatric care can be complex; its definition depends on the context and perspective and is influenced by several factors. This study examined the perceptions of female patients and caregivers re

We employ small-angle x-ray and dynamic light scattering to investigate the microscopic structure and dynamics of dense suspensions of ultra-low crosslinked (ULC) poly(N-isopropylacrylamide) microgels. By probing the supercooled and glassy regimes, we characterize the relationship between the structure and dynamics as a function of effective volume fraction φ and probed length scale. We demonstrat

The explosion of new digital media puts pressure for developments within copyright law both in Sweden and internationally. These developments are taking place on two different international areas: (1) WIPO which is a part of the UN family and (2) the EU where a new directive on copyright law is being prepared and probably implemented during 2001. The aim of this thesis is twofold: (1) to study whi
