Det moderna övervakningssamhället är förknippat med omfattande ljudupptagning i offentliga rum, på arbetsplatsen och även i hemmet, vilket motiverar ökad användning av s.k. talanonymiseringstekniker. Att värna rätten till privatliv samtidigt som övervakningskapaciteten säkerställs är balansgången detta examensarbete tar itu med i två delar. Möjligheten att blint extrahera hela talsegment ur ljudupThe modern society is associated with widespread sound recording in public environments as well as in the workplace and at home, which motivates an increased use of speech anonymisation techniques in recorded audio. A demonstrative example is masking recorded speech in hospitals' waiting rooms for eavesdropping listeners inside a control room, thus ensuring privacy of information. This thesis

The goal was to investigate how novice entrepreneurs shape their decision-making process to manage uncertainty in the early stages of their ventures. Utilizing qualitative interviews conducted between March and April of 2024, this study delves into the different strategies used by novice entrepreneurs

In the rapidly evolving electric vehicle (EV) battery industry, strategic supplier selection is crucial for securing a reliable and cost-effective supply chain. This thesis examines the implementation of a capacity analysis and a should-cost model to optimize supplier selection and contracting for Northvolt, a leading battery manufacturer, as it expands into North America. With Northvolt's new

The industrial sector of Sweden used 136 TWh of energy 2022 out of which the agricultural sector used 6.09 TWh. The goal of the country is to become 50% more energy efficient by 2030 compared to 2005. Furthermore, Sweden’s long-term target is to achieve net zero greenhouse gas emissions by 2045. From 2005-2022 the total energy use of the agricultural sector has been reduced by 16% but previous stu

Syftet med uppsatsen är att undersöka vilka erfarenheter lärare har av systematiskt kvalitetsarbete, samt vilka möjligheter och begränsningar de identifierar med arbetssättet. För att besvara frågorna används kvalitativa intervjuer med sju lärare som arbetar vid en kommunal högstadieskola. Empirin har analyserats med hjälp av organisationssociologisk teori och perspektiv på organisering av offentl

Flera miljarder dollar går uppskattningsvis förlorade årligen p.g.a. något tämligen väldigt enkelt; omblandning. Det finns alltså oerhörda förbättringsmöjligheter inom detta område i olika industrier, vilket detta arbete handlar om. Omblandning eller mixning är ett mycket vanligt steg i olika tillverkningsprocesser i livsmedelsindustrin, där ingredienser oftast mixas i en omblandad tank till en hStirred tanks are essential components in design and optimization of food processing lines, as they assure proper mixing and homogenization of ingredients. In this context, the mixing time is one of the most impactful performance parameters affecting various process design decisions. Thus, reliable methods to accurately predict mixing times in stirred tanks are highly desired. The aim of this the

Optimering av flödet till en förångare i ett kylsystem ökar effektiviteten. Experiment visar hur prestandan kan förbättras med geometriska förändringar i inloppsröret till en förångare med ett homogent flöde. Detta leder till en förbättrad fördelning av köldmedia i förångaren följt av förbättrad effektivitet. Snedfördelning av köldmedia i ett kylsystem påverkar systemets kylförmåga, men med geometRefrigerant systems such as chillers and are widely used to create a comfortable indoor climate, often incorporated in large buildings or offices. It relies on a refrigerant circuit that lowers temperature of a coolant via a heat exchanger, called an evaporator. The coolant enters a fan coil which lowers the surrounding air temperature in a desired space and recirculates back to the evaporator at

Business angels play a crucial role in stimulating the growth of early-stage ventures. They are key players in the venture financing market, providing both financial support and experience from their own entrepreneurial experiences. As the entrepreneurial landscape has historically advantaged males, leading to its male-predominance, previous studies raise awareness of how business angels, particul

Bakgrund: Forskning visar att aktivitet och delaktighet är viktigt för en persons hälsa. Vikten av att utföra aktiviteter i en miljö med rätt förutsättningar är beforskat. Forskningen om ickebinäras hinder och möjligheter att deltaga och utföra aktiviteter är begränsad. Syfte: Undersöka ickebinära personers upplevelse av hinder och faktorer som möjliggör aktivitet och delaktighet i Sverige. MetodBackground: Research shows that occupation and participation are important for a person’s health. The importance of being able to do occupations in an environment with the right conditions has been studied.However, research on what enables nonbinary people to participate and do occupations is limited. Aim: To investigate nonbinary people's experiences of what enable and hinder occupation and

Cybersäkerhet är en pressad utmaning i dagens samhälle och är en strategisk prioritering som kräver omfattande arbete. Denna studie utforskar de faktorer som påverkar implementeringen av cybersäkerhetsstrategier inom organisationer. Genom att använda Technology-Organization-Environment (TOE) ramverket, analyseras hur tekniska, organisatoriska och omgivningsmässiga aspekter påverkar cybersäkerhetså

Etik är något som påverkar alla människor. Interaktioner mellan människor implicerar nödvändigheten av etiska överväganden. Ju komplexare situationer dessa interaktioner består av, desto mer övervägande krävs det. En sådan interaktion är rekrytering. Rekrytering innebär mellanmänskliga interaktioner av en komplex art, vilket kräver etiska överväganden som inte kan förklaras av våra vardagliga uppf

Background: The rise of influencer marketing, fuelled by globalisation and social media popularity, has led to an increased ethically contested promotion of aesthetic surgery by influencers. Existing research has primarily focused on consumers, leaving the influencer perspective and their ethical justifications largely unexplored. Purpose: To explore the ethical justifications of social media infl

This study aimed to engineer and characterize a series of Amelogenin-ELP fusion proteins to explore their potential as biomaterials with enhanced properties. Eleven constructs (176-186) were designed and expressed in E. coli BL21(DE3) cells, with successful purification confirmed by SDS-PAGE. Dynamic Light Scattering (DLS) revealed that constructs 181, 185, and 186 formed nanospheres similar to fu

This study evaluates a methanol compression ignition engine's stability, performance, and emissions using glow plugs at low loads. A Scania D13 engine modified to run on methanol was tested to assess the impact of glow plugs on combustion stability, engine efficiency, and emissions characteristics, particularly in combination with various injection strategies. The research objectives focused o

This thesis examines the nascent sector of cultivated meat in Europe, analysing its potential market penetration against the backdrop of evolving consumer attitudes, complex regulatory frameworks, and innovative business models. Given the pressing environmental concerns associated with traditional meat production, cultivated meat presents a sustainable alternative that promises to reshape the meat

Audio Description (AD) is developing fast, becoming the norm for big streaming platforms. However, the research field remains largely underexplored. When comparing AD practices between countries, studies seem to focus on guidelines rather than how these are used, or not, by audio describers. Additionally, not enough emphasis is placed on cross-varietal differences of English AD, and in cases when
