Descartes "onda demon" och kristen livskonst

René Descartes’ Meditations on First Philosophy explores foundational philosophical and theological questions through a method of radical skepticism. Central to this exploration is the concept of the evil demon, a hypothetical being that challenges human capacity to comprehend and perceive reality. Descartes’ meditations are pivotal to the development of rationalist philosophy, bridging epistemolo

Evaluation of natural wetlands in Kigali - A field study on the effects on water quality

Sedan 1700-talet har 87 procent av världens våtmarker försvunnit, med en acceleration under de senaste 50 åren där mer än en tredjedel av världens våtmarker försvunnit på grund av exploatering. Våtmarker bidrar med många viktiga funktioner, såsom klimateglering genom att minska översvämningar och torka samt genom att agera som naturliga reningsverk. I takt med klimatförändringarna har våtmarkers fWetlands play a vital role globally in protecting biodiversity, purifying water, and mitigating floods. In Kigali, Rwanda’s capital, five natural wetlands are located in the city center. This master’s thesis aimed to evaluate the water quality of these wetlands and identify key pollution sources. The aim was also to analyse changes in water quality over time with respect to changes in demographics

Täby Galoppläktare - Ett transfomationsprojekt om hur man kan förlänga en byggnads liv

På grund av klimatkrisen har det blivit allt viktigare att förändra våra konsumtionsvanor och ta bättre hand om det vi redan har. I arkitekturens kontext innebär detta att vi tar hand om och transformerar de byggnader som redan existerar i våra städer. Dessa byggnader är mer än bara strukturer och material, dem är en del av vår historia och kultur. I stället för att riva de byggnader som inte läng

Sediment Transport in the Piura River. Piura, Peru. An application with the HEC-RAS model.

This thesis is an investigation of sediment transport in the Piura River in Peru. Years of anthropogenic changes have redirected the river towards the south and have caused changes in the flow regimen (Alvarado Ancieta & Ettmer, 2007). It is suspected that the redirection towards the south has resulted in deposition of sediments which has reduced the capacity of the river in the lower reaches

Who Drives the Price Reaction After Earnings Announcement?

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

Amphibian Architecture: Dwelling in a Wetland

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

Mobility and Cultural Constraints in E.M. Forster’s Maurice and Stephen Spender’s The Temple: Portrayals of Homosexuality in Early 20th-Century Literature

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

3D Shape Estimation Using Single Camera Setup and Laser Mesh Pattern

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

Testing and Establishing of Material Models for Rubber Gaskets in Heat Exchangers using DIC

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

Design and Evaluation of a Novel Low-Power Rectifier for RSSI in IEEE 802.11ax Wi-Fi Receivers

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

Skissernas Museum - en studie i byggnadens särart samt förslag på tillbyggnad

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 insatsstöd - Data från smarta byggnader som ett stöd för räddningstjänsten

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

Aktieåterköps påverkan på avkastning: En empirisk studie av återköp genomförda på Nasdaq Stockholm

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

Integrering av automationstillämpningar i det decentraliserade systemet Vario-X - Implementering och testning av användningsområden

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.
