This master’s thesis investigates tool bending in solid carbide end mills during shoulder milling of CK45 steel, SS 1.4923, SS 316L, and TiAl6V4. Five different tool designs were tested to evaluate the influence of cutting speed and feed rate on tool deflection, surface quality, and machining stability. The results show that feed rate has a stronger effect on tool bending than cutting speed. High
This study investigates the relationship between military expenditure, economic growth, and technological progress in 27 OECD countries over the period 1970–2019. While previous research on the economic consequences of military spending has produced mixed and often inconclusive results, this paper extends the literature by including total factor productivity (TFP) as a measure of long-term technol
This study investigated the effects of using multiple different acoustic and linguistic features for objective Speech Reception Threshold (SRT) estimation from Electroencephalography (EEG) data, using models that estimates the neural response (EEG data) from the corresponding feature stimulus, or vice versa. The SRT is a measurement of the speech volume Signal-to-Noise Ratio where the subject unde
In this thesis, optimization of cross-laminated timber panels is performed. A cross laminated timber panel consists of a set of wooden layers, which are bonded together. In this work, a layer of elastomer is included among the wooden layers. As the elastomer is a favourable material to improve the vibrational and acoustic properties, this thesis investigates how this material can be optimally dist
I Sörmlands sydöstra kustlandskap, på Tunabergshalvön, ligger den lilla bruksorten Buskhyttan. Orten har goda geografiska förutsättningar att utvecklas som en aktiv landsbygdsort, där man kan leva ett liv närmare naturen men ändå ha nära till arbete och stad. Den uppkom i och med etableringen av ett sågverk år 1917, men sedan slutet av 1970-talet har verksamheten varit nedlagd och sågområdet lämnaIn the southeastern coastal landscape of Södermanland, on the Tunaberg Peninsula, lies a small mill town called Buskhyttan. It is strategically placed within its community and has the potential of being a well connected and active rural area where you can live a life closer to nature. The town emerged with the establishment of Marsvikens sawmill in 1917, but since the end of the 1970s the industry
I ett individualiserat och sekulariserat samhälle har frågor om mening, gemenskap och psykologiskt välmående aktualiserats inom såväl forskning som samhällsdebatt. Självtranscendens har föreslagits som en möjlig psykologisk resurs i denna kontext, men har i begränsad utsträckning undersökts i relation till kollektiv samhörighet och välmående i en svensk population. Syftet med föreliggande studie vIn increasingly individualised and secularised societies, questions of meaning, social connectedness, and psychological well-being have gained attention in both research and public discourse. Self-transcendence has been proposed as a potential psychological resource in this context but has rarely been examined in relation to collective belonging and well-being within a Swedish population. The aim
The accelerating global energy transition has intensified demand for energy transition minerals (ETMs), many of which are located on or near Indigenous lands. While ETMs are essential for decarbonisation, their extraction often reproduces entrenched patterns of socio-ecological injustice and generates new pressures on Indigenous Peoples, territories, and ways of life. Free, Prior and Informed Cons
Micronization is a key process in the pharmaceutical industry, particularly in the production of inhalable particles which have to be in the size range of 1-5 µm. Particle size reduction in a spiral jet mill is a complex process which has been investigated theoretically and empirically resulting in complex equations. In this project a simple equation for describing micronization energy (Eµ) and a
Short-term wave prediction is a key enabling technology for advanced control of wave energy converters (WECs), where accurate knowledge of the incident wave field over one to a few wave periods can improve power capture, reduce structural loads, and support operational decision-making. Many existing prediction methods rely on measurements at the prediction point or dedicated up-wave sensors, which

This thesis investigates the detection of acute heart failure (AHF) in an exvivo heart perfusion system using hemodynamic signals. Early detection of AHF is important for improving monitoring and intervention. Experimental data was pre-processed and transformed into a beat-to-beat representation, from which physiological features were extracted. Events were labeled based on manual reductions in pu
Detta kandidatarbete undersöker transformationen av den historiska Marieholms Yllefabrik till ett modernt kontorshotell. Syftet är att genom arkitektonisk återanvändning väcka liv i ett industriarv som stått sysslolöst sedan 2002 och därmed bidra till lokal vitalisering och hållbarhet.Visionen fokuserar på mötet mellan gammalt och nytt, där fabrikens befintliga betongstruktur och tegelfasader beva
This paper compares neologism formation in five Indigenous languages of Northeastern Brazil that are currently undergoing revitalization or post-dormancy recovery. With a focus on the coining of nouns and numerals, the study categorizes neologisms according to morphological (e.g. compounding, derivation, borrowing) and semantic processes (e.g. extension) and assesses their distribution of these ac
Following the outbreak of new media technologies, researchers in museum studies have acknowledged the increasing importance of digital content creation for museums. Today, Social Media provides museums with the opportunity to engage with their audiences beyond museum walls and pursue their organizational mission in innovative ways. Despite a growing interest in the organizational changes that make
The average build year for existing multi-family buildings in Sweden is1959, circa 95 % of building built before 1960 uses natural ventilation and circa 45 % of these have failed the obligatory ventilation control that exists in Sweden. In the EU buildings stand for 30 % of the total energy usage and the aim is to get buildings to a near zero energy building. The aim of this thesis is therefore to
This thesis discusses the development of Product Category Rule (PCR) for semiconductor Back-End (BE) processes. While Life Cycle Assessment (LCA) are common practice in the industry, there is currently no PCR specifically for BE processes, which creates inconsistent reporting of emissions. This thesis provides a meta-analysis of allocation methodologies for semiconductor packaging. The meta-analys
When there is a statement of deficiency given to a nursing home, the Centers for Medicare & Medicaid Services (CMS) requires facilities to submit a plan of correction stating how they will create systemic change to prevent recurrence of the incident. This study reviewed 90 statements of deficiency and associated plans of correction from across the United States for abuse, neglect, and exploita
