The aim of this thesis is to study whether high retail ownership of a firm impacts the market response to an earnings announcement. To this end, I utilize the traditional event-study methodology in combination with cross-sectional regression. The latter is used to examine whether a company’s ownership structure affects abnormal returns. Two event windows were analyzed, a three-day window and an el
A case study house for a regenerative architecture. What would a regenerative architecture look like, in the context of a wetland landscape? With climate catastrophes becoming the new reality for an increasing amount of communities, floods among them, how would we live in a landscape, and with what materials would we build, in order to mitigate these issues? How do we live with a landscape, inste
E.M. Forster’s Maurice (1971) and Stephen Spender’s The Temple (1988) were written at the beginning of the 20th century and they both portray narratives of what life could look like for men who experienced attraction towards other men at the time. In this essay I examine how homosexuality is represented in Maurice and The Temple, and in what ways the portrayals of homosexuality in the two novels r
In biological observation of small flying animals, structured light methods can be used in order to make high frequency, no contact measurements in flight. Using a laser pointer that projects a 5625 point mesh pattern, as well as two high-speed cameras, three different methods for estimating the shape of 3D objects have been developed and evaluated. The cameras were calibrated, as well as the lase
The marine environment faces significant changes due to anthropogenic activities, with urbanisation and "marine sprawl" introducing artificial structures that disrupt natural ecosystems. Artificial reefs (AR) and nature-inclusive design offer solutions to enhance habitat complexity and foster ecological restoration. This thesis investigates how AR design and material properties can suppo
Testning och materialmodellering av gummipackningar i värmeväxlare För att en plattvärmeväxlare ska kunna fungera på ett effektivt sätt är det viktigt att ha packningar som klarar den höga belastningen. Detta examensarbete har inneburit att testa och anpassa nya materialmodeller för ett antal packningsmaterial för att förbättra utvecklingen i framtiden. Examensarbetet är gjort i samarbete med AlThe aim of this master's thesis is to establish material models for three rubber materials using macroscopic data collected using Digital Image Correlation, DIC. DIC is a non-contact optical technique for measuring strain and displacement in a material by tracking points on a material during the deformation process.\\ The rubber materials are tested in both uniaxial tension and compression, fr
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
The Museum of Artistic Process and Public Art – An exploration of the building’s distinct character and a proposal for an extension. In Lund, you’ll find a museum unlike any other – the Museum of Artistic Process and Public Art (Skissernas Museum). Renowned for its exceptional collection, it has also been my workplace for the past two years. This building, which I came to know in detail through my
Smart firefighting is a concept in which the rescue service uses technological aids to retrieve, compile and present data as part of intelligence gathering to work out their firefighting strategy. The aim of this report is to map what kind of sensors in present-day smart buildings management systems that may offer relevant data in terms of operational support for the rescue service. Interviews hav
The number of listed companies that decide to buy back their own shares has increased significantly in Sweden in recent years. This paper examines whether buybacks of companies listed on Nasdaq Stockholm have resulted in abnormal returns for the companies' shares. The study covers buybacks carried out during the period 2015 to 2024. The return is measured as the cumulative return from the da
Examensarbetet fokuserar på implementering och testning av automationstillämpningar inom det decentraliserade, modulära systemet Vario-X, utvecklat av Murrelektronik AB. Vario-X är en automationsplattform som skapats för att föra ihop alla komponenter direkt vid en maskins kärna, vilket tar bort behovet av skåp och minskar komplex kabeldragning. Plattformen är modulär, energieffektiv och erbjuder This thesis focuses on implementation and testing of automation applications within the decentralized and modular system Vario-X, developed by Murrelektronik AB. Vario-X is an automation platform created to bring all components together directly at the core of a machine, which in turn removes the need for cabinets and reduces complex cable routing. The platform is modular, energy efficient and off
Examensarbetet fokuserar på utformningen av ett boende för äldre och personer med demens, där naturens positiva inverkan på hälsa och välbefinnande har varit en central utgångspunkt. Projektet syftar till att skapa en miljö som främjar återhämtning, möjliggör utevistelse och social samvaro samt underlättar för både personal och anhöriga. Byggnaden är placerad i ett grönområde i Lund, i närhet til
I denna rapport jämförs två olika grundläggningsmetoder med fokus på deras praktiska tillämpning och tillhörande klimatpåverkan i urbana miljöer. Syftet är att undersöka, belysa och öka kunskapen om mindre beprövade grundläggningsmetoder i Sverige, samt öka förståelsen för deras potentiella fördelar. Jämförelsen fokuserar på hur en permanent bärande sekantpålevägg utförd med CCFA-metoden kan vara This report presents a comparative analysis of two foundation methods, focusing on their practical implementation and environmental impact in urban environments. The aim is to examine and enhance understanding of less commonly used foundation techniques in Sweden, while also evaluating their potential advantages. The comparison specifically investigates whether a permanently load-bearing secant pi
Workplace social media monitoring has become increasingly prevalent, raising critical concerns about privacy and fairness in employee-employer relationships. This thesis investigated the associations between the Big Five personality traits and employee perceptions of social media monitoring in the workplace. Using a quantitative research design, the study examined how openness, conscientiousness,
Hur lär AI bäst av grafdata? Genom att strukturera data som matematiska grafer kan vi låta AI lära sig relationer mellan allt från vetenskapliga artiklar till personer i ett socialt nätverk. Men hur graferna ska designas kan visa sig vara avgörande för hur väl dessa AI-modeller presterar. Majoriteten av världens data är sparad i relationsdatabaser. Dessa består av tabeller där varje datapunkt ärGraph Neural Networks (GNNs) are increasingly used for predictive tasks on data where relationships between entities are best represented as graphs. Much work has been done to improve GNN architectures, but how the ac- tual data graph should be designed is not well studied. In this Master’s Thesis, we investigate how different graph representations, specifically node classification and link predic
