During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. In this study the porosi
Volunteer tourism is an alternative form of tourism that is constantly increasing. The increase can be considered related to trends about social participation, environmental awareness and moral demands. Volunteering in developing countries has previously been associated with altruism and social responsibility, but more recently volunteer organizations have used personal development as part of thei
Wheel of Fortune or Academy of Vice? : Economic Ideals and Threats in the Swedish Lottery Debate, 1809–1840. This master’s thesis examines how ideas pertaining to economic and moral behaviour, ideals and threats were expressed, shaped and understood in the public debate about the state lottery – kungliga nummerlotteriet – in Sweden during early nineteenth century. At the time, state lotteries wer
Streptococcus pyogenes is a host-adapted human pathogen responsible for causing various infectious diseases, including rheumatic heart disease and acute rheumatic fever, some of which can be fatal to humans. The bacteria contain different pathogenic proteins situated on the cell surface or secreted extracellularly. Many of these proteins have the ability to bind to and activate human plasminogen.
Sverige och Tyskland skiljer sig i nivå av jämställdhet som råder i länderna. Det finns få vetenskapliga undersökningar hur förändringar i jämställdhet i ett samhälle manifesterar sig i heterosexuell dejting, särskilt i förändringar av användning av dejtingskript. Denna brist finns särskilt i Sverige och Tyskland. Syftet med denna uppsats är att analysera och jämföra användning av det klassiska de
Detta är en studie och jämförelse av speltekniska förutsättningar på Boehmflöjt, alt-, bas- och kontrabasflöjt. Utgångspunkten ligger i tekniska aspekter som fingerteknik, embouchure, artikulation och luftförbrukning. Även en jämförelse av nya speltekniker och hur dessa svarar på respektive flöjt förekommer. Undersökningarna har genomförts med stöd av erkänd flöjtlitteratur, praktisk övning samt sThis is a study of technical conditions and a comparison of the Boehm flute, alto-, bass-, and contrabass flute. The study involves technical aspects such as fingering, embouchure, articulation, and air consumption. In addition, there is a comparison of how commonly used extended techniques respond on the different flutes. The surveys of this thesis have been conducted through studying well-known
Objectives: This project aims to develop a deep learning-based attention decoding system that can distinguish between noise and speech in noise and also identify the direction of attended speech from the brain data recorded with electroencephalography (EEG) instruments. Two deep convolutional neural network (DCNN) models will be designed: (1) one DCNN model capable of classifying incoming segments
In this thesis, the subject of data-driven control of Unmanned Surface Vehicles (USVs) is explored. The control task is formulated through Nonlinear Model Predictive Path Following Control (NMPFC). System identification (SYSID) and Reinforcement Learning (RL) are employed to improve performance in a data-driven manner. The objectives were to assess the resulting controller’s path-following ability
Gängkriminaliteten är ett omtalat ämne som det kontinuerligt har forskats om. Forskningen har utvecklat kunskap gällande varför individer blir gängkriminella och vilka faktorer som gör att gängkriminella är kvar i gänget. Däremot finns det mindre forskning om vilka insatser som är effektiva för att lämna gänget och varför. Den aktuella studien syftade till att sammanställa den internationella forsGang criminality is a much-discussed topic that is extensively researched. The knowledge gained from the research explains why individuals become gang criminals and which factors make gang criminals remain in the gang. However, there is less research on which interventions are effective for leaving the gang and why. The current study aimed to compile the international research literature on the in
This study investigates xenoliths present in various dykes on Tenerife, the Canary Islands. These xenoliths were studied by means of fieldwork, petrographic analysis, scanning electron microscopy, laser fluorination, and LA-ICP-MS. In conjunction these analyses enable the understanding of the magmatic structures beneath the Anaga massif, with a conceptualisation of the formation of this volcanic s
This thesis studies the possibility of estimating the ambient temperature around a mobile phone using its internal temperature sensors. The thesis aims to develop and evaluate ambient temperature models that use internal temperature sensors within the device and, from a manufacturer’s perspective, investigate if the models for ambient temperature can be enhanced by tailoring them to the internals
Treatment planning plays a vital role in providing good treatment to cancer patients. In order to reach an adequate treatment plan, the algorithm used for simulating the dose in the patient must model the reality well. The most accurate algorithm for this is the Monte Carlo method, which in the context of radiotherapy treatment most often is used for pre-computing spot doses and optimizing the int
Denna studie undersöker möjligheterna att öka användningen av data inom fysisk handel och syftar till att förstå hur beslutsfattare kan generera värde från besöksräknarteknologi. Genom en kvantitativ forskningsansats undersöker studien potentialen hos moderna teknologier inom handelssektorn och introducerar Data Acceptance Model (DAM) som en teoretisk modell för att förstå acceptansen av data. Res
At its core, language is multimodal (Kendon, 1986; McNeill, 1994), and information presented through different channels of information, such as visually, in the shape of gestures, or verbally, in the shape of speech or signs, together facilitate online language processing (Kelly, Healey, Özyürek, & Holler, 2015; Kelly, Özyürek, & Maris, 2010). This thesis extends previous studies on multim
This thesis investigates how the traumas of the Holocaust and the Nakba have been utilized by Israeli and Palestinian political elites in media rhetoric during the first month of the 2023 Israel–Hamas war. With the theory of the transmission of chosen transgenerational traumas as a point of departure, this study finds that political leaders have frequently utilized historical traumas as points of
Previous research has seen populist leaders emerge globally and focus on how they change security dynamics. The field is relatively new, and the relationship between populist leaders and security issues is an ongoing debate, whether tensions create populist leaders or generate insecurity. This thesis investigates how constructions of internal and external threats change security discourses over ti
This thesis employs a theoretical framework of everyday nationalism, Social Identity Theory (SIT) and violent discourse theory to examine nationalism and identity-based violence among Serbian post-war football supporters. The Serbian supporter scene is known internationally because of the ideological standpoints brought forward in the stands, motivating a multimodal discourse analysis of these mul
Denna uppsats utforskar de utmaningar som industriföretag möter vid implementering av Manufacturing Execution Systems (MES). Genom en kombination av teoretisk forskning och en kvalitativ intervjuansats undersöks hur teknologiska, organisatoriska och kulturella faktorer påverkar framgången för MES-implementeringar. Studien identifierar kritiska aspekter såsom behovet av en stark strategisk vision,
This paper examines how the framing of NATO has changed in Russian foreign policy in the 21st century. The Russian perception and portrayal of NATO is very much interconnected with Russian behavior on the international stage. For a greater understanding of Russian foreign policy, a content analysis of the Russian foreign policy concepts has been conducted with framing as a theoretical perspective.
The General Data Protection Regulation (GDPR) has been called the strictest data protection law in history, and one of the key reasons for this is due to its vast territorial scope, which allows it to be applied to non-EU entities as long as the relevant conditions are met. Such a broad extraterritorial application has greatly improved the level of data protection, but it has also triggered some c
