Elektromagnetism och speciellt elektromagnetiska vågor är grunden till nästan all modern trådlös överföring. Elektromagnetiska vågor kan liknas vid ljus och karakteriseras av frekvens, där endast ett fåtal frekvenser ger upphov till ljus som är synligt för människoögat. Mycket av den trådlösa överföringen som dyker upp i vardagen syftar till någon form av kommunikation, såsom WiFi, Bluetooth och 5The merging of communication and sensing in the same transmission chain has become an increasingly relevant prospect as it allows for better coordination between users at the same time as it more effectively utilize the available frequency bands which are becoming increasingly crowded. Orthogonal frequency division multiplexing (OFDM) radars is one way to combine the two by applying the common mod

Skogen är en viktig naturresurs, men dess kapacitet att stötta de ekosystemtjänster vi är beroende av beror på hur skogen mår. Dagens skogar i Sverige och Finland är dominerade av trakthyggesbruk som resulterar i kalhyggen med sämre förmåga att stötta biodiversitet och ekosystem. I Finland har man under de senaste åren ökat sin andel hyggesfritt skogsbruk i statligt ägda skogar vilket enligt stForestry in Fennoscandia is currently dominated by conventional rotation forestry, but an increased interest in continuous cover forestry (CCF) methods has been observed in both Finland and Sweden. The Finnish state-owned enterprise Metsähallitus has since a couple of years used CCF in 25% of their forests, and this paper aims to identify factors that could hinder or prove disadvantageous for Svea

This body of work covers the utility of the development of a tool for automatically configuring the transistors in an existing netlist, according to a set of specifications. By swapping out transistors for transistors with other Voltage Thresholds it can achieve target speeds with acceptable accuracy and reduce the static power consumption of a circuit. To make this process feasible, the tool uses

This thesis contributes to the field of business model innovation and organizational change within incumbent firms by applying a process-oriented approach to investigate servitization. In particular, it seeks to improve understanding of the elements that influence this process, namely the use of past learning, organizational culture, and organizational readiness within incumbent firms. These topic

The Large Hadron Collider (LHC) at CERN is undergoing a major upgrade to prepare for the High-Luminosity LHC. It will allow for many more particle collisions to occur. Some detectors that make up the LHC experiments must be replaced to withstand the harsher conditions. In particular, the inner tracking detector (ID) of the ATLAS experiment will be replaced by the new Inner Tracker (ITk). Every co

Focusing on the complexity of power relations is fundamental to understand and address the effects of climate change. For this reason, this thesis focuses on understanding how climate change impacts affect power relations both between men and women, and between people and nature, in the context of Tutimayu, a territory in rural Bolivia. To provide an adequate analysis of these two types of power r

This thesis investigates the enhancement of solar drying techniques for agricultural produce, focusing on achieving uniform drying to reduce post-harvest losses. Conducted in Bhutan, a developing country in the Himalayas with abundant sunlight but limited preservation infrastructure, the study aimed at constructing an efficient and affordable solar dryer. The primary objectives were optimizing air

Extremväder, såsom torkan 2018, förväntas öka i framtiden på grund av den pågående globala uppvärmningen. Detta kommer bland annat påverka världens skogar, vilka är viktiga i klimatsystemet, framför allt på grund av deras förmåga att binda koldioxid, men även deras utsläpp av biogena volatila organiska kolväten. Skogarnas förutsättningar att bidra till klimatsystemet på detta sätt kan dock ändras Extreme weather events, such as heatwaves and droughts, are predicted to increase due to global warming, significantly impacting forest ecosystems. These ecosystems play a crucial role in the climate system through carbon sequestration and the emission of Biogenic Volatile Organic Compounds (BVOCs), which can form Secondary Organic Aerosols (SOAs) and thus have a cooling effect on the climate. In

The protein amyloid beta (Aβ) is a major component in the amyloid plaques associated with Alzheimer’s disease. This project concerns the most common version of this protein, Aβ40. In a supersaturated solution, Aβ40 monomers can aggregate to form amyloid fibrils. The solubility of an amyloid protein is equal to the concentration of the monomeric peptide in solution at equilibrium. To study the solu

This thesis is an exploratory, qualitative analysis of the participants in English-language YouTube audiovisual content featuring reactive playthroughs of Japanese horror video games. The aim is to understand the identity, motivations and lived experience of these participants to understand how they culturally translate Japanese horror. The research draws on data collected from one semi-structured

Denna studie utforskar de potentiella hoten mot maskulinitet som uppfattas i samhällen med hög könsjämlikhet och undersöker om sådana hot kan kopplas till en ökning av incel (ofrivilligt celibat) karaktärsdrag bland den manliga befolkningen. Forskningen använder en kvantitativ metod med två experimentella villkor: ett med en hög jämställdhet och ett med en låg jämställdhet, som skildrar kontrasterThis study explores the potential threats to masculinity perceived in societies with a high gender equality and examines whether such threat can be linked to an increase in involuntary celibate (incel) traits among the male population in. The research employs a quantitative methodology with two experimental conditions: one featuring a high equal scenario and another a low equal scenario, depicting

This thesis conducts an in-depth investigation of the conformal two Higgs doublet model (C2HDM) in its most general form, integrating complex couplings λ5, λ6, λ7 and a CPviolating phase e−iδ. This setup enables a detailed exploration of $\mathcal{CP}$-violation and its impact on electroweak phase transitions (EWPT) and gravitational wave (GW) signatures. Using the Higgs basis simplifies tree-le

This thesis posits that the 1948 mermaid film Miranda, made in the United Kingdom is an example of a pivotal moment, or series of moments, in mermaid image history. Through Aby Warburg’s method of the Bilderatlas, the thesis will identify and map out how Miranda connects with surviving mermaid images and created new image types that are now prevalent within modern mermaid images. Through this mapp

Social sustainability is of growing concern for global businesses as EU legislation CSRD, entered into force January 2024. The legislation requires businesses and enterprises to report on their social sustainability impacts. United Nations Guiding Principles on Business & Human Rights (UNGPs) is the framework where human rights due diligence is explicitly described as an important tool for ide

Leaf Area Index (LAI) is an important parameter for monitoring vegetation status and estimating crop yield, essential for precision agriculture, forestry and natural resource management. Therefore, estimating the LAI with high spatial resolution and temporal flexibility is crucial for providing precise and timely information to make informed decisions. This study focuses on optimizing the estimati

Mangrove forests are highly productive and vital ecosystems within the tropical and subtropical latitudes. They are considered biodiversity hot spots and hosts ha vast variety of species, both terrestrial and marine, and they are also found to be one of the most productive carbon pools in the world. Mangroves additionally provide coastal communities with timber but also important shelter from tsun

The purpose of the study was to study the overall support given to community-placed children, their birth parents and foster parents when a child is placed in care. The different supports have therefore been studied and inventoried by collecting data from a total of (n=254) respondents from more than 85 Swedish municipalities. The respondents were professional social workers working within social
