Spänningsmätningar och laserdiagnostik lär oss om brandsäkerhet i batterier. Som du förmodligen känner till är användningen av fossila bränslen som drivmedel till bilar skadlig för både människor och miljö. Istället är elbilar en lösning som många biltillverkare satsar på idag. Volvo Cars har till exempel beslutat att alla bilar som säljs år 2030 ska vara helt eldrivna. Utvecklingen av elbilsbatDue to the environmental impact of fossil fuels, there has been a growing interest in lithium-ion batteries for electric vehicles. However, safety concerns have arisen regarding potential fire hazards associated with the vent gases of these batteries. This work aims to investigate the role of electrical discharge as a proposed ignition source of battery vent gases. A set of research questions for

ChatGPT är det senaste tillskottet inom AI-teknik, en konversationsmodell skapad för att svara på frågor och producera text. Trots att ChatGPT är mycket uppmärksammat och har blivit en allt vanligare del av människors vardag, är tidigare psykologisk forskning kring denna funktion begränsad. Därför ansågs det intressant att fördjupa sig inom detta samhällsaktuella ämne. Studien valde att undersöka ChatGPT is the latest addition in AI technology, a conversational model created to answer questions and produce text. Although ChatGPT is receiving a lot of attention and has become an increasingly common part of people’s everyday life, previous psychological research on this feature is limited. Therefore, it was considered interesting to delve deeper into this socially relevant topic. The study c

Previous research has shown that the relationship between the news and parliament is complex and highly variable. Studies have found that in many countries, parliament has minimal influence on the news. However, in the UK, a reciprocal influence between parliament and the news was found, with the media having a stronger effect. This thesis investigates how the news and parliament affect each other

This research followed a qualitative approach using a cross-sectional study design. Ten semi-structured interviews with employees from four different venture builder organizations are the primary data source. The data is inductively analyzed using Gioia, Corley,

Studien undersöker integrationen av IoT-data i befintliga BI-system och dess relevans för kort- och långsiktiga beslut samt begränsningar som är förknippade med användningen av denna typ av data. IoT har blivit alltmer integrerat i organisationers verksamhet men forskningen kring dess relevans till BI-system är fortfarande begränsad. Genom intervjuer med olika organisationer och analys av insamlad

Behovet av att skapa hållbara och flexibla byggnader har vuxit under de senaste åren, inte minst för att möta högt uppsatta klimatmål. Utrymmena mellan byggnaderna, med andra ord utemiljöer, har regelbundet prioriterats sekundärt och anpassats i stor utsträckning efter det bebyggda behovet. Utemiljöer i urban kontext innehåller ofta mer eller mindre kollektiva varor, som är icke-exkluderbara och iThe need for sustainable and flexible buildings has grown in recent years in order to meet climate goals. However, outdoor environments have often been overlooked and is often strongly controlled by the built environment. These spaces hold significant social and ecological benefits but pose challenges for real estate companies as they lack direct financial returns. Well-designed outdoor environme

The Anatomy of Expectation. Dreams of Social Mobility in the Swedish Baltic Sea Area, 1680–1770 Social mobility in the early modern period has been subject to extensive research, often with an interest in quantities, ideologies, and strategies. The personal driving forces behind this mobility, on the other hand, remain obscure. Focusing on servants of the state in the Swedish Baltic Sea area betw

Utilizing the Double Machine Learning (DML) framework with both Partially Linear Regression (PLR) and Interactive Regression Models (IRM), this study examined the crucial role of parental education in the early detection of Autism Spectrum Disorder (ASD). Analysis was conducted on comprehensive data from the National Survey of Children's Health spanning the years 2017 to 2021. A significant ne

As for now, there is a need for more information and understanding about how variations in 316L steel affect the deformation of sheet steel to produce steel pieces. Therefore, this project aims to present the material's variation regarding chemical composition, mechanical properties and coil dimensions. Furthermore, experiments are conducted to evaluate the quality of deformed steel pieces and

The aim of this study was to investigate The Salvation Army's work with human trafficking for sexual purposes since it is a specialized organization in civil society that has a long history of working with this issue. Research shows that overall, the Swedish agencies neither have the competence, nor the knowledge, needed to meet the issue. We, as coming social workers wanted to investigate wha

Information and communication technology has emerged significantly over the past two decades.

The purpose of this thesis is to investigate the techniques that scammers and scambaiters use in phone conversations to deceive each other and accomplish their respective goals. Seeing how the number of people losing money to scams continues to rise every year, there is an urgent need for more research to raise awareness of common scam tactics. It is also highly sociologically relevant to gain an

In this master’s thesis we propose a DensePose-based person re-identification (re-ID) machine learning algorithm building upon previous research on this topic. DensePose, a deep neural network that performs human body part segmentation on images, forms the foundation of our approach. We investigate whether utilization of DensePose can enhance performance on re-ID algorithms with the utilization of

The recycling of plastic has the potential to support circular material use, thus decreasing the need for virgin plastics. However, there is an existing issue with assuring quality of recycled plastic materials, causing finished products to perform with poorer properties and unexpected deviations. Based on a thermoformed plastic packaging product, Product Y, made of recycled high density polyethyl

As a part of this so-called European Green Deal, the Fit for 55 package was

När vi tittar ut i universum ser vi bara materia, även fast vi vet att antimateria finns. Enligt teorin borde antimateria, som är precis som vanlig materia fast med motsatt laddning, producerats i lika stora mängder vid Big Bang. Partikelacceleratorn LHC i Schweiz genererar lika mycket materia och antimateria i partikelkollisioner som påminner om de som skedde i samband med Big Bang. Så det skulleThis thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry. We define a modified renormalization schem
