In this thesis, a novel method for characterizing Permanent Magnet Synchronous Machines(PMSMs) based in the dynamic response of the analyzed motor is evaluated. The most significant motor characteristics -torque, flux and efficiency maps- are computed from the motor voltage, currents and rotor position data sampled during the experiment. This way of obtaining the characteristics of the motor is po

Inversion recovery (T-1) and microwave power saturation studies have been performed, between 4 and 25 K, on the EPR signal from the stable tyrosyl radical, Y-D(.), in photosystem II core complex preparations from higher plants. Measurements are reported from the dark stable S-1 and first turnover S-2 states of the photosystem catalytic Mn cluster and in two cryoprotectant regimes; sucrose and ethy

A flexible method of preparing and macroscopically aligning nanoparticles of crystalline silver into millimeter long fibers is presented. The approach utilizes the dual functionality of a reverse hexagonal liquid crystalline template containing a built-in reducing agent facing the aqueous domain. The method is advantageous in that its slow kinetics allows for a thorough introduction of a silver sa

Based on the perspective of LGBTI-activists, the aim of this study was to analyze the policy processes that frame homosexuality in Uganda, as well as to illuminate different powerful stakeholders involved in the debate with power in the policy process. In October 2009, Member of Parliament David Bahati tabled the Anti-homosexuality Bill in Uganda. The drafting of the Bill condemns people convicted

The cross-border region of Øresund is one of the areas in Northern Europe where the largest concentration of highly educated people reside. Other authors argue that the integration process of the region has seemingly come to a halt due to a lack of interest from the inhabitants. This thesis argues that the young citizens of Øresund offers a shift in tendency towards the region and does so by takin

Small island states, such as those in the Caribbean, are dependent on the nearshore marine ecosystem complex and its resources; the goods and services provided by seagrass and coral reef for example, are particularly indispensable to the tourism and fishing industries. In recognition of their valuable contributions and in an effort to promote sustainable use of marine resources, some nearshore are

Abstract Metal oxide semiconductor (MOS) capacitor was fabricated on the InGaAs substrate with Al2O3/HfO2 gate oxide. InGaAs is one of the promising candidates for advanced applications which require the lower power supply and high frequency. The high-k films (Al2O3/HfO2) were formed by atomic layer deposition (ALD) as an alternative to silicon dioxide (SiO2) to proceed the scaling of oxide to low

Objective Although Parkinson's disease is a common disorder in the elderly, there have been very few studies of the role of the pharmaceutical care services in detecting and reducing problems associated with drug treatment in community settings. The aim of this study was therefore to investigate the type and frequency of drug-related problems identified in patients with Parkinson's disease by comm

Even though recent studies suggest that a high intake of heme iron is associated with several types of cancer, epidemiological studies in relation to gastric cancer (GC) are lacking. Our previous results show a positive association between red and processed meat and non cardia gastric cancer, especially in Helicobacter pylori infected subjects. The aim of the study is to investigate the associatio

Lung cancer is a common cause of cancer mortality in the world, largely due to the risk factor of tobacco smoking. The drug therapy at the molecular level includes targeting the epidermal growth factor receptor (EGFR) tyrosine kinase activity by using inhibitors, such as erlotinib (Tarceva) and gefitinib (Iressa). The heterogeneity of disease phenotypes and the somatic mutations presented in patie

Telomere length and telomere shortening are thought to be critical cellular attributes and processes that are related to an individual's life span and fitness. The general pattern across most taxa is that after birth telomere length gradually decreases with age. Telomere protection and restoration mechanisms are usually assumed to reduce the rate of shortening or at most keep telomere length const

The principle of patient self-determination is central to contemporary medical ethics. However, many uncertainties remain regarding its implementation in healthcare. This thesis explores, from an ethical perspective, situations in nephrology care that reveal barriers to patient self-determination or where the requirements of the principle are unclear. The thesis includes three published articles a

Classical model reduction techniques project the governing equations onto a linear subspace of the original state space. More recent data-driven techniques use neural networks to enable nonlinear projections. While those often enable stronger compression, they may have redundant parameters and lead to suboptimal latent dimensionality. To overcome these issues, we propose a multistep algorithm that

The timing of the spring season in the boreal region is shifting under global warming, with profound impacts on ecosystems and hydrological processes. However, the mechanisms driving this transition and its considerable interannual variability are not well described, especially regarding the influence of large-scale atmospheric teleconnection patterns. This study examines the temporal variability

Introduction: Widening participation in education by including students from underrepresented groups has been recognized as important for the last decade. During the recent pandemic, the interest in how to make students from different backgrounds feel part of the university, and connected to their studies and peers, has become an even more widespread concern and therefore important to explore furt

Popular Abstract in Swedish Datorsimuleringar, konsten att modellera verkliga eller tänkta händelser med hjälp av en dator och ett lämpligt simuleringsprogram, har blivit ett dominerande verktyg inom tekniska och naturvetenskapliga områden, likväl inom akademiska och industriella tillämpningar. Trots att experimentella studier har ett vedertaget erkännande inom diverse forskningsstudier har den snThis thesis concerns the study of Fluid-Structure interaction phenomena among deforming and (non-deforming) vibrating objects under unsteady fluid fl ow exposures. This multi-physical phenomenon is widely encountered in real-life situations and therefore it is of significant importance to understand the underlying physics. The trend is that both industrial and research facilities aim for developi

As a result of the globalisation of the world economy, many enterprises that previously confined their business activities to national markets are now focusing on broader international markets, thus forming the basis for the establishment of global enterprises. In addition to the extension of markets, these global companies also seek cost reductions through scale economics in logistics, marketing,

Within the paradigm of population dynamics a central task is to identify environmental factors affecting population change and to estimate the strength of these effects. We here investigate the impact of observation errors in measurements of population densities on estimates of environmental effects. Adding observation errors may change the autocorrelation of a population time series with potentia

Following the development of large-scale use of biomass energy in the EU, international biofuel trade is a plausible scenario and something that is already taking place in Northern Europe. This paper focuses on Swedish biofuel imports, both direct and indirect imports, the latter which derive from the fact that part of the imported pulpwood and timber end up as fuel. The objective is to describe t
