This thesis aims to provide a suggestion to how a chair could be designed to have less negative impact on the environment. At many offices the turnover of furniture is big. By conducting interviews and study visits, it was indicated that chairs used in lunch areas and meeting rooms are the type of furniture that gets exchanged the most in office environments. Many of the existing chairs used for t

Life is generally viewed to be priceless, however, for an economy to work, there has to be some sort of value-placement on human life. The concept applied to attain such a value-placement is called the value of statistical life. This study seeks to identify if there is a connection between the value of statistical life in different countries and what implications such a result might hold. Using Mi

Startups. Why are the odds of surviving the initial stages so low? While the internet revolution has made it easier to start up, for example by democratizing investments through crowdfunding, the rate of success is still daunting. Why? Ultimately, the world is still being built by humans. That means a group effort is required. To realize this, leadership is an undeniably crucial element. Yet, not

I Lund accelereras elektroner av superkorta och energirika laserpulser i ett plasma. Elektronerna accelereras från stillastående till väldigt nära ljusets hastighet på bara några få millimeter. Förhoppningen är att kunna ersätta dagens större och dyrare sätt att accelerera elektroner. Nyligen invigdes i Lund den stora synkrotronljusanläggningen MAX IV. Vid MAX IV accelereras elektroner i en långLaser wakefield acceleration (LWFA) utilises a high intensity laser pulse to excite a plasma density wave with associated large directed electric fields. These large electric fields can be used to accelerate electrons, making LWFA a good candidate for a compact electron beam source. In this dissertation, the impact of small fluctuations in laser pulse energy on the generated electron bunch charg

Populärvetenskaplig sammanfattning Genetisk variation och genuttryck i Langerhanska öar Projekt 1 - Genetisk variation DNA är den mänskliga cellens informationslagringsenhet och består av långa sekvenser av de fyra nukleotiderna adenin(A), tymin(T), cytosin(C) och guanin(G). Proteiner kan binda till DNA och översätta delar av dessa sekvenser(gener) till RNA, en liknande typ av molekyl. RNA kanAbstract This article describes the creation of a pipeline for variant calling from high-throughput next-generation exome and RNA sequencing data using commonly used bioinformatics tools. High-throughput sequencing data from six pancreatic islet cell samples were analyzed using the pipeline, and the resulting variant calls were validated against chip genotyping data from the same individuals. The

This is the report of a thesis work about controlling an autonomous wheel loader. The objective of the work was to create a complete prototype of an autonomous wheel loader that can operate without any seated driver and without any kind of remote controlling. Another important objective was that this prototype needs to support future development of the autonomous wheel loader. The work was complet

Passwords are one of the most used tools for authentication. Because of this, password managers have been developed to allow for increased protection and usability when managing passwords. However, the research of password managers in the context of usability coupled with diffusion of technology is unclear. Thus, the study’s purpose is to investigate how usability influences management of and the

The aim of this paper is to examine how the covid-19 pandemic and the restrictions around have effected domestic violence against women in Sweden. The year 2020 has been affected hard by the coronavirus spreading throughout the world. Alot of nations applied a lockdown strategy to fight the spread of the virus. Sweden choosed to handle things differently and let the government give out recommendat

Studier har visat att det kan göras bra bedömningar av trafiksäkerhetstillstånd och dess bidragande faktorer genom att studera konflikterna i trafiken istället för olyckorna. Genom att undersöka hur konflikterna i en trafikplats ser ut kan man få mer data och få den mycket snabbare än om man undersöker olycksdata. Genom att använda nya verktyg till datorer som djupinlärning kan man även lättare ta

With unrest prominent in the entire world, cybersecurity is more important than ever before. With this, the need for education and strengthening practices within critical infrastructure and organisations is growing. This master’s thesis is done in collaboration with the Swedish Defense Research Agency (FOI) and aims to create a new Graphical User Interface (GUI) for their cybersecurity tool Scanni

Olagliga transaktioner i form av bland annat penningtvätt, insiderhandel och marknadsmanipulation är stora problem som ofta glöms bort. Bara under 2020 tvättades 1.6 biljoner dollar världen över, motsvarande 2.7\% av världens totala BNP. Insiderhandel och marknadsmanipulation bidrar till misstro för marknaden vilket gör att den till lägre grad kan allokera pengar till företag från investerare då fIllegal transactions in the form of money laundering, insider trading and market manipulation is a major problem that is often forgotten. In the year of 2020, 1.6 trillion dollars were successfully laundered, corresponding to 2.7\% of the world's total GDP. Insider trading and market manipulation contribute to mistrust of the market, resulting in worse capital distribution from investors to co

In the fall of 2022, Sweden's most significant social service that is located in Malmö City went through a major organizational change. The goal of the reorganization was that it would be easier to manage the daily operations, collaborate internally, and primarily handle cases equally when the respective departments were located in the same buildings. The aim of this study is to gain the persp

Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting. B

This master's thesis investigates the feasibility of implementing field-oriented control for a BLDC motor without relying on a position sensor from a standstill up to 400 rad/s. To achieve this objective, various approaches were used at standstill and high speeds. The high-frequency injection method was used at standstill and lower speeds, while a method based on estimated magnetic flux was ut

Title: Resistance and uncertainty in change processes. How can dialogue and participation be used to ensure a successful implementation of a change initiative? Author: Cathrine Westlie Eidal Advisor: Charlotte Simonsson Problem: Resistance and uncertainty towards change are the main problems why change initiatives fail. There is also a lack in the literature when it comes to how the employees perc

Objective: To limit the research time by developing a theoretical model, that can predict the lifetime of a wheel with the help of different input values. Apart from a theoretical model, also create a different type of test rig that can decrease the testing time, and still produce an accurate result similar to a real situation. Method: This Master’s Thesis was based on both an investigatory method

Whole-cell recordings were obtained from mossy fibre terminals in adult turtles in order to characterize the basic membrane properties. Calcium imaging of presynaptic calcium signals was carried out in order to analyse calcium dynamics and presynaptic GABA B inhibition. A tetrodotoxin (TTX)-sensitive fast Na+ spike faithfully followed repetitive depolarizing pulses with little change in spike dura

The topic of this thesis is estimation of nonlinear dynamical systems, focusing on the use of methods such as particle filtering and smoothing. There are three areas of contributions: software implementation, applications of nonlinear estimation and some theoretical extensions to existing algorithms. The common theme for all the work presented is the pyParticleEst software framework, which has b
