The body shows impressive control capabilities in terms of the speed and the precision with which movements can be carried out under a wide variety of circumstances. The cerebellum and brainstem nuclei, including the cuneate nucleus, are believed to play a crucial role in this control. If these control mechanisms can be unveiled, this could yield important insights in not only medicine and neuroph

This work presents an observer design for grid current and capacitor voltage of voltage source pulse-width modulation (PWM) converters with LCL filter. Theoretical aspects including the mathematical LCL filter system observability, observer placement strategy and practical discretization implementation. It gives insight to mathematical modelling of the line filters dynamics. By the limitations of

This paper explores freshwater reservoir greenhouse gas emissions from a policy perspective. Existing science on reservoir emissions indicates that reservoirs can emit significant amounts of greenhouse gases and this is of particular concern for tropical reservoirs. Current scientific knowledge has led to some precautionary policy measures, but, in general, policy development has been slow. At the

The Sami people have a long history of colonization, discrimination, marginalization and prosecution in their past. My thesis deals with how the Sami identity is created and reproduced today and how it has been shaped in the light of the history of the Sami people and the policies pursued by the Swedish government through times, and also why the search for identity, heritage and roots has had such

The aim of this study is to 1) describe the structure and types of associational and organizational networks within immigrant women’s community in southern Sweden Malmö, Lund and Eslöv, 2) examine how such networks facilitate Thai women’s well-being and integration by providing social supports and services, and 3) present how Thai women perceive the role of social and organizational networks in re

The academic interest in remote work has drastically increased over recent years, particularly during the COVID-19 pandemic. Existing studies have proven that remote work has advantages and disadvantages for employers and employees. However, little is known about the influence of remote work and the relevant factors in the context of newcomers and their organizational socialization. Building on th

Denna masteruppstats ämnar utröna lönsamheten och de faktorer som påverkar lönsamheten vid ingåendet av en kort position i finansiella derivat på den nordiska elmarknaden samtidigt som motsvarade position anskaffas genom handel på Nord Pools day-ahead (DA) marknad och via så kallade pay-as-produce Power Purchase Agreements (PPA), samt genom tillämpandet av batterilager för att mitigera effekterna This master’s thesis aims to assess the profitability and the factors impacting the profitability of entering a short position in financial derivative contracts on the Nordic power market while procuring electricity through a pay-as-produced power purchase contract and on the day-ahead (DA) market, simultaneously the strategy utilizes a battery storage system to mitigate the effects of price spike

An important factor in preventing food waste is the ability to provide a product with a package according to its needs. The packaging material, in turn, needs to be recyclable in order to contribute to a circular use of materials rather than becoming waste. The aim of this thesis is to examine the difference between the current and future packaging material of coffee produced by Zoégas. The curren

Strong narrowband interference can significantly degrade the sensitivity of wideband receivers by driving front-end circuitry into nonlinear operation. This thesis presents the design, fabrication, and measurement of a 2 – 4.4 GHz electrically tunable varactor-based bandstop filter that can follow and block such narrowband interference before it causes problems in the receiver. It was developed us

Acoustophoresis enables label-free separation of particles and cells in microfluidic sys- tems, but systematic methods for analysing and comparing separation behaviour re- main limited. In this thesis, a workflow based on the mobility ratio was evaluated as an experimental framework for characterising acoustophoretic separations, using flow cytometry as the analytical tool. Separation experiments

Battery electric trucks and autonomous driving systems are each approaching commercial viability for long-haul freight. Current development treats these technologies as independent improvements to diesel operations. This thesis examines the operational and economic synergies that emerge when autonomy and Megawatt Charging System infrastructure are deployed together rather than in isolation. The a

Aortic valve stenosis is a common congenital heart defect among children. In affected patients, the normal tricuspid valve structure is malformed into a bicuspid valve structure due to a fusion at one commissure. A common treatment is transcatheter balloon valvuloplasty, where a balloon is inserted through the aortic valve and inflated to mechanically tear the fused region, restoring a tricuspid s

How can we understand Gällivare municipality as a sacrifice zone through local narratives of green transition? The transition to low-carbon economies in the wake of the European Green Deal drives increased demands for metals and minerals, renewable energy, biomass from forests – intensifying green extractivism. In Gällivare municipality, located in the rural north of Sweden and within the borders

Introduction Illicit maritime activities frequently involve "dark" vessels that disable or manipulate their Automatic Identification System (AIS) signals to evade detection. This study evaluates the effectiveness of Synthetic Aperture Radar (SAR) and Optical imagery for vessel detection using both “manual” and automated Deep Learning (DL) methods while integrating AIS data to validate, i

Received Signal Strength Indicator (RSSI) circuits are critical in modern Wi-Fi receivers, playing a key role in power management and protecting the radio frequency (RF) front-end from saturation and potential damage. This thesis presents the design and evaluation of a novel rectifier circuit conceptualized for use in an RSSI system within an industry-standard 22nm CMOS node, specifically targetin

This thesis explores various aspects of urban design and societal factors that contribute to creating child-friendly environments. The study begins by examining child-friendly design, emphasizing the significance of considering children’s needs in urban planning. Following this, a city-wide analysis of Reykjavík is conducted, exploring the swimming pool culture, the preschool and school system, an

Forensic sexual assault samples typically contain a mixture of a small quantity of sperm cells and a high quantity of epithelial cells. This relationship complicates the generation of a DNA profile, which prompts the need for differential lysis and extraction of the DNA. Differential extraction is a lengthy method that includes multiple tube transfers and requires a purification step. Amicon Ultra

The building sector contributes to one-fifth of Sweden’s total greenhouse gas emissions (GHG) and consumes 40 % of the final energy consumption. To achieve the climate goals set by the Swedish government, the building sector requires rapid development to reduce its climate impact. The climate impact of buildings comes from two types of energy throughout the building's lifecycle: operational an

Background: Purchasing and Supplier Relationship Management are becoming increasingly important as companies’ competitiveness increases. One part of this is Supplier Performance Evaluation (SPE), which is part of the final step in the purchasing process and can be performed in many different ways. SPE can ensure that suppliers are performing as expected and when not, actions can be taken. When mea
