[8]annulene units linked by alternating benzo[a,e]moieties are a promising new design for electro-responsive hydrocarbons. However, current methods for synthesizing benzo[8]annulenes limit the prospect of constructing longer multimers. In this work, an alternative synthesis route to the compound containing two [8]annulene moieties was pursued. The dimeric compound was ultimately furnished over thr
This thesis explores the philosophical and historical perspectives of Ibn Khaldun and Oswald Spengler regarding the cyclical nature of civilizations. By analyzing Ibn Khaldun’s Muqaddimah and his theory of asabiyya (social cohesion), alongside Spengler’s kulturseele (cultural soul) in The Decline of the West, the study examines their respective explanations of the rise and fall of societies. Ibn K
Wireless communication encompasses a wide range of applications, demonstrating its versatility in various domains. For example, it can be utilized to enable access control through the use of tags, act as a deterrent against theft in retail settings, or support global and interstellar communication. What all of the different use cases have in common is that they work by employing radio frequency tr
Gläntans camp vid Fiskeboda i Sörmland välkomnar unga vuxna på autismspektrumet att koppla av, ha roligt och träffa nya vänner under skolledigheterna. För vissa är det första gången de är borta hemifrån, för andra är det en efterlängtat höjdpunkt på året. Oavsett om du kommer som deltagare eller som en del av personalgruppen. Under några veckor varje år är det ett hem bortom hemmet. Många minnen
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
Wetlands 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
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
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
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
The 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
