This project designs an RF switch operating in E-band to provide a transmit path from a Class-F power amplifier (PA). The basic RF switch is based on the single-pole double-throw (SPDT) topology using shunt transistor switches and two λ/4 transmission line. The transistors used in this project are nanowire MOSFET transistors developed by the Division of Electromagnetics and Nanoelectronics, LTH, L

In this thesis we consider multiplicative integrals and derivatives on functions on the positive numbers, the logarithmic Riemann surface and the punctured complex numbers. Additive structures on the real and complex numbers are related to their multiplicative counterparts on the positive numbers and the logarithmic Riemann surface by defining exponential transition functors. We use a lift-project

The employment effects of expansionary fiscal policy have been well documented in the literature. Interestingly, however, limited attention has been paid to the gender dimension. Across countries, significant gaps in female and male employment still remain. This, together with the risk of hysteresis, makes it central to examine how expansionary fiscal policies affect female and male employment and

Syftet med studien var att undersöka vilken påverkan en helgkurs i autentiskt relaterande hade på kvaliteten i deltagarnas relationer. Relationskvalitet mättes i två kontexter: Mellan kursdeltagarna respektive i deras befintliga relationer utanför kurskontexten. Syftet var att undersöka om kursen påverkade relationskvaliteten mellan deltagarna och om deltagarna kunde dra nytta av nya färdigheter fThe purpose of this study was to investigate the impact a weekend course in authentic relating had on different aspects of the quality of the participants' relationships. The relationship quality was measured in two contexts: Between the course participants and in their existing relationships outside the course context. The aim was to investigate whether the course affected the quality of rela

There is extensive research on creativity and innovation, as well as the question of whether UGC and social media platforms foster creativity or dumb down culture. There is however a gap in research on how creative and innovative UGC is. The purpose of this study is therefore to investigate the creative motivations behind creating UGC and whether the UGC on TikTok is applicable to creative and inn

The goal of this article is to propose, through the use of GIS software, an interdisciplinary method to suggest new touristic flows after the Covid-19 pandemic. Specifically, the aim is to identify those sites of cultural and landscape interest that are little known but with great artistic, cultural, historical and environmental value that could give new vigour to the tourism sector. In the first

In this master thesis nanowires have been simulated to study the effect of spatial imperfections in the nanowires. This spatial imper- fection took the form of potential fluctuations in the conduction band across the wire. To achieve this, scripts were written in MATLAB to simulate the nanodevices by applying the non-equilibrium Green’s function (NEGF) method. To verify the simulations, multiple q

This thesis is about the limiting eigenvalue distribution of n × n Toeplitz matrices as n → ∞. The two classical questions we want to answer are: what is the limit set of the eigenvalues, and what is the limiting distribution of the eigenvalues. Our main result is a new approach to calculate the limit set Λ(b) for a Laurent polynomial b, i.e. for banded Toeplitz matrices. The approach is geometric

SKOGSÄGARES RELATIONER TILL SKOGEN ÄR VIKTIGA FÖR BIOLOGISK MÅNGFALD OCH LAGRING AV KOLDIOXID. Privata skogsägare äger ungefär 50% av den svenska skogen. Att skogen behövs för att minska klimatpåverkan är de flesta överens om, men hur den bäst ska göra det har varit föremål för debatt. Ska den avverkas med kalhyggen för att ersätta fossila material och bränslen, eller ska den stå kvar för att lagThe starting point of this study is the perspective of Swedish private forest owners. From that point of view, I aimed to discover the possible influences of values on climate mitigation and biodiversity in Swedish forests. The focus of both climate mitigation and biodiversity is of great importance as these are two major crises the world faces, and yet solutions are often seen as conflicting. By

I denna uppsats undersöks hemsidan och pedofiljägargruppen Dumpen.se ur ett journalistiskt perspektiv. Utifrån teorier som Hallins sfärer, gestaltningsteorin och boundary work är syftet med denna uppsats att undersöka hur Dumpen.se gestaltas i medierna. Detta görs med hjälp av kvalitativ textanalys, där materialet består av tolv artiklar och reportage från svenska medier under året 2022. För att r

Bakgrund: Akut buksmärta tillhör de vanligaste orsakerna till att söka vård. Obehandlad akut buksmärta kan leda till fysiska och psykiska komplikationer. Sjuksköterskan har en central roll i att minska lidande. Sjuksköterskans omvårdnad påverkas av olika barriärer. Syfte: Syftet var att undersöka barriärer i sjuksköterskans omvårdnad av patienter med akut buksmärta. Metod: Icke-systematisk littera

El propósito de esta tesina es estudiar la manera en la que las novelas Cielos de barro y La voz dormidø de Dulce Chacón están construidas y cómo se inscriben en una parte de la historia de España. Ambas novelas abarcan la época de la Guerra Civil y los años de la dictadura y resulta interesante estudiarlas, ya que son escritas por la misma autora y tratan el mismo problema con dos estilos diferen

We develop a deep learning model that uses financial news articles and historical exchange rates to predict the rate for the Euro/US Dollar currency pair one hour ahead. From the articles’ titles and bodies we extract sentiment scores using two different transformer based classifiers – one for short text and one for long text. The long-text classifier is built and trained by us. These sentiment sc

Breast cancer is the most frequently diagnosed form of cancer worldwide. 2 260 000 people were diagnosed with breast cancer year 2020, and 685 000 people deceased from it. In low income countries, breast cancer is commonly detected at a later stage when it is harder to treat, thus entailing a higher mortality rate. This is primarily due to the lack of knowledge and diagnostic tools available. A lo

Syftet med denna studie var att undersöka patienters upplevelse av psykologisk behandling för depression, med betoning på mening, motivation och förändring. Studien använde kvalitativ metodik, specifikt tematisk analys med en kritisk-realistisk epistemologisk grund. Fem vuxna deltagare rekryterades och intervjuades semi-strukturerat. Materialet transkriberades, kodades och tematiserades. Det förstThe purpose of this study was to examine patients’ experiences of psychological treatment for depression, with an emphasis on motivation, meaning, and change. The study used qualitative methods, specifically thematic analysis with a critical realist epistemological foundation. Five adult participants were recruited and interviewed with semi-structured interviewing techniques. The material was tran

Syftet med studien är att utreda huruvida det går att härleda valet av ett kollektivt respektive ett individuellt belöningssystem till i vilken grad uppgiftsosäkerhet och uppgiftsberoende förekommer inom branschen. Syftet är med andra ord att undersöka om contingencyteorin kan användas för att bättre förstå i vilka kontexter ett visst belöningssystem används.Studien har utförts med en kvantitativ

The discourse on Angela Carter’s The Bloody Chamber has primarily been focused on the feminist undertones of her neogothic fairy tale retellings. In this essay, I apply the male and female gaze to Carter’s collection, which are perspectives I believe previous research on Carter’s works has overlooked. The incorporation of the male gaze allows for a further nuancing of Soloway’s female gaze, and my

Alfa Laval believes Supply Chain Control towers have the potential to harvest the power of digitalization in industrial manufacturing supply chains more efficiently than the alternative of applying those same digital technologies in a context without a control tower. One of the most common supply chain control tower applications is in the inventory management field. In this area, it is relevant to
