The many-body problem is one of the most challenging problems in physics due to the complexity emerging from the interactions of many quantum particles. Since the advent of computers with increasing power, computational methods have been very successful in providing insight and precise solutions to this problem. We give an introduction to two canonically used methods, density functional theory and
As the world moves more and more towards automation of repetitive and dangerous tasks there are still many tasks that primarily involve interaction with an object that are still carried out by humans. This is in many ways due to difficulties in programming the robot to achieve similar performance. The most natural way of transferring these skills to the robot is by demonstration. This can be achie
Image feature extraction has become a key technology in the field of autonomous Artificial Intelligence. The algorithm Oriented FAST and Rotated BRIEF (ORB), uses established technologies in image processing to allow a computer to ”see” and navigate its surroundings. This process, however, is very performance intensive, but a field-programmable gate array (FPGA), a programmable semiconductor devic
We study the problem of reducing polarization (variance) of opinions at stationarity in a directed weighted graph with node set divided into two groups: stubborn, initialized with a fixed opinion and regular who repeatedly update their opinion to the average of their out-neighbors, known as the DeGroot model with stubborn nodes. We show how the polarization can be minimized for a number of simple
Bakgrund och problem: Belöningssystem är ett av de styrmedel som kan användas inom ekonomistyrning, detta innebär att organisationens ledning använder olika belöningar för att motivera sina anställda till att arbeta på det sätt som är mest fördelaktigt för organisationen. Individanpassade belöningssystem kan vara en utmaning för organisationer i och med att motivation skiljer sig mellan olika indi
This empirical study attempts to assess the use of French (and other languages) within a European institution to illustrate the following: the daily practical French used within a single directorate-general, the awareness at the directorate of how France is trying to increase the use of French especially during the French presidency 2022, and the attitude and use of French inside and outside the w
Småskalig plattform för upprening av monoklonala antikroppar Utvecklingen av en uppreningsplatform för antikroppar visar en 30% ökning i produk-tivitet med hjälp av parallella flödesbanor. Det är nu också möjligt att upprena ännu fler prov per körning än tidigare. Utvecklingen av nya antikroppar blir allt mer viktigare i dagens samhälle för att kunna förbättra vår analytiska och diagnostiska föThe aim of this project is to transfer and implement a monoclonal antibody purification process that is traditionally done on an ÄKTAxpress to another machine called the ÄKTA pure. This is due to the fact that the ÄKTAxpress is being discontinued by the manufacturer and a replace-ment machine is needed for the time being. The project will include developing some new meth-ods that might also highli
Background: Psoriatic arthritis (PsA) is an inflammatory joint disease occurring in up to 30% of psoriasis patients. Relatively few clinical trials assess PsA treatment and data presentation in these are far from uniform making comparisons difficult. Objectives: To perform a literature review on methotrexate (MTX) efficacy in PsA. Research questions were: What evidence support MTX monotherapy in
Evidensparadigmet har sedan 80-talet varit rådande inom psykologin som vetenskap och praktik. Kritiker till evidensparadigmet menar emellertid att den positivistiska forskning, framförallt RCT-studier, som bedrivs inom paradigmet vilar på antagandet som inte överensstämmer med den psykoterapeutiska praktiken. Syftet med föreliggande studie var att, genom kvalitativ metod, jämföra hur ett urval av The evidence paradigm has dominated the field of psychological practice and research since around 1990. Critics however, have adressed the research-practice gap, suggesting that the positivistic research, such as RCT-studies, conducted within the paradigm are based on assumtioms that are ill fitting with the reality of clinical practice. The aim of the present study is, using a qualitative method,
Enkel ögondiagnostik - Snart i ett hem nära dig? Inom den moderna sjukvården utvecklas ständigt verktyg som kan underlätta för sjukvårdspersonalens vardag genom att snabbt och enkelt kunna ställa korrekta diagnoser av en uppsjö av olika sjukdomar. Speciellt sjukdomar eller symptom med tydlig koppling till ögonrörelser har visat sig lämpliga att diagnostisera med teknik kopplad till eye tracking. Eye tracking technology has been a great addition to medicine, psychology and behavioural science. Its contribution to diagnosis and the understanding of specific eye diseases should not be understated. However, eye tracking technology is often complex, expensive, immobile and usually requires users that can keep still for longer periods of time. These prerequisites are at times not possible, and
The purpose of this report is to provide knowledge about what factors that contribute to the recruitment and retention of people among volunteer firefighters in small rural communities. The report also aims to provide ideas of how to promote a sustainable retention of volunteers in rural rescue services. The factors have been identified through various study methods with data obtained from a liter
Business Improvement District (BID) har blivit en alltmer förekommande modell för att utveckla utsatta områden i Sverige. BID-modellen är relativt outforskad i svensk kontext, men har sedan dess första inträde i USA och Kanada både blivit hyllad och kritiserad. Trots att tidigare forskning är oeniga om modellens förtjänster så råder det i princip samstämmighet angående modellens auktoritära inslag
Blockchain technology offers a new type of financial infrastructure with the potential to increase financial participation and decrease transaction costs. The technology behind it is hard to fully wrap your head around, likewise it’s different versions, potential and downsides. This paper aims to investigate two things. Firstly, what is blockchain technology and digital currencies? Secondly, how c
På senaste tiden har allt mer medial uppmärksamhet riktats mot den problematiska arbetsmiljön i flera delar av välfärden, inte minst för socialsekreterarna. Det talas om för hög arbetsbelastning och personalomsättning, och för låg personalstyrka och lön. Den psykiska ohälsan vid socialtjänsten är bland de högsta rapporterade i Sverige. Syftet med denna kvalitativa studie var därför att undersöka h
Är det helt omöjligt att ta död på parkslide? Nej men frågan är om priset är värt det. Hetvatten som var den bekämpningsmetod som hade bäst effekt i det här arbetet är väldigt dyr och måste dessutom göras ofta under en längre period. Slaghackning, den andra bekämpningsmetoden som undersöktes kostar inte mycket men verkar inte heller kunna utrota bestånd av parkslide. Metoden kan däremot användas fJapanese knotweed is a big problem in Sweden and there is no known control that can eliminate stands of the plant. Therefore the aim with this thesis is to investigate the effect on Japanese knotweed of two control methods: mowing and hot water. The control methods chosen are the ones used by the Ängelholm municipality since this thesis is done in collaboration with them. The methods were investig

Famine has played an essential part in the rise and fall of many civilizations. Yet, many considers the plight of famine a phenomenon of the past, reserved for but the poorest parts of the world. In Europe there are plenty examples of famine and hardship during the 19th century. When the most recent famine in Swedish history struck the area of Småland during the 1860s, the mortality distribution d
