This thesis investigates the use of several acceleration schemes to improve the performance of the primal-dual hybrid gradient algorithm for linear programming (PDLP), a state-of-the-art first-order method for linear programming (LP). The three main acceleration schemes investigated are: Polyak heavy ball momentum, Nesterov acceleration, and steering vectors selected in a residual momentum directi
The report investigates whether ultra-high-frequency ultrasound at 30 MHz can distinguish healthy- from diseased intestinal tissue in infants with Hirschsprung's disease with the same accuracy as 50 MHz. Hirschsprung's disease is defined as the absence of ganglion cells in the distal parts of the intestine. During treatment, the affected sections of the intestine are surgically removed. Th

As there currently are not so many known studies which directly evaluate how diversity indices have been used in different contexts, following literature study was made with the purpose of investigating how three of the most commonly used diversity indices (including Shannon-Wiener’s and Simpson’s Indices as well as a certain index measuring taxonomic diversity) are representing different categori
Syftet med studien är att undersöka vilka faktorer som påverkar styrkan i ett företags strategiska position. Styrkan klassificeras som graden av svårighet konkurrerande företag har att inta det egna företagets position. Syftet uppnås genom att applicera en kvalitativ fallstudie på Rynkebys lansering på den svenska markanden. The Resource Based View (RBV) och dess isoleringsmekanismer samt ConsumerThe purpose of this study is to investigate which factors affect the strength of companies strategic position. The strength is defined by how hard it is for a competing firms to enter the strategic position. The factors are derived by applying the Resource- Based View (RBV) and it’s Isolation Mechanisms as well as Consumer Benefit Experienced (CBE) and it’s Human Capital based strategies on a case
Sammanfattning År 1987, kom Brundtlandkommissionens rapport med titeln Vår gemensamma framtid. Enligt rapporten så kan hållbar utveckling definieras som: En utveckling som tillfredsställer dagens behov utan att äventyra kommande generationers möjligheter att tillfredsställa sina behov. Begreppet hållbar utveckling har ända sen dess varit en central del av alla internationella miljörättsliga dokuSummary In 1987 the Brundtland commission presented its report entitled Our Common Future.

The term sustainable development has been a central part in all international environmental law documents eve
Uppsatsen behandlar vissa frågor kring rättsinstitutet särskild granskning enligt aktiebolagslagen. Särskild granskning tillhör aktiebolagslagens minoritetsskyddsregler och ger en minoritet av aktieägare rätt att genom Bolagsverkets försorg få en särskild granskare utsedd. Genom en specialundersökning kan avgränsade förhållanden i bolaget som är av extraordinär natur granskas. Förarbetena har uttaThe thesis deals with certain questions concerning the legal institute’s special examination according to the Swedish Companies Act (SCA). Requesting a special examiner is a part of different protection controls for minority shareholder in SCA and gives a minority of shareholders the right to get a special examiner appointed by the Swedish Companies Registration Office (SCRO). By conducting a spec

People that have driven a car with a trailer at high speed know that the trailer can begin to oscillate. This oscillation is known as snake behavior. How much the car and trailer starts to oscillate depends on how the trailer is loaded. An empty trailer does not tend to oscillate, while a heavy loaded trailer, with the load centered over the trailer axle, oscillates more easily. For a normal perso
Mental crisis is according to Johan Cullberg (2006) a reaction pattern in which a person suffering from acute internal or external stresses which occur when one's life experiences and behaviour are not sufficient to cope with the new life situation you are in. We think that we as future social workers often can come across mental crisis in our work. As we think we don´t learn enough about ment
Populärvetenskaplig sammanfattning Geografiska Informationssystem (GIS) är ett system för att hantera geografisk data som jämfört med traditionella forskningsmetoder gör det lättare att sammanställa och analysera dessa data. GIS började utvecklas i Nordamerika på 1960-talet och har under de senaste två decennierna haft stor påverkan på hur hanteringen av rumslig data går till. Användningsområdena Geographical Information System (GIS) is a technique that has revolutionized the way we process spatial data. The possibilities for GIS are endless and it is today used in a wide range of subject areas such as social planning, environmental monitoring and marketing. However, the process of implementing GIS is a long and usually runs in to a lot of problems. The aim of this study is to compare and
Om ett ekosystem ska fortsätta att förse samhället med viktiga tjänster måste det vara anpassningsbart. Som en del av ett ekosystem är arters förmåga att förflytta sig över landskapet vitalt för anpassningen. Grönstruktur underlättar förflyttningen av arter i ett landskap fragmenterat av bebyggelse och barriärer. Vid ett förändrat klimat är grönstruktur viktigt av två anledningar. Ökat antal extreFor an ecosystem to be able to continue to provide important services to society, it must be able to adapt to change. As part of an ecosystem, the ability of a species to migrate in the landscape is vital for the adaption to change. A green infrastructure allows the movement of species in a landscape fragmented by human influenced land use. The importance of a green infrastructure is twofold in a
The cultural board of region Skåne decided fall of 2008 to reorganize the fundings of the cultural pedagogy. What the reorganization implicates is that the everyday practice of the pedagogues will not be paid for by the region, and instead the pedagogues will focus on capacity building and competence maintaining towards all of those who work pedagogically with children. They will work in five diff

This essay deals with eight women, who all left their native country Bosnia because of the war. Before the flight, each individual is a human being with a role and a place in the structure of society. After the flight, she suddenly finds herself in an unknown community, after having lost her land, her culture, family, friends and identity. The purpose of this essay was to try to give a backdrop of
This study examines and compares theoretical CDS spreads created by a structural framework with empirical CDS spreads. The model employed is the CreditGrades model based on the Merton framework from 1974 which calculate default probabilities and credit spreads from balance sheet and equity data. The aim is to measure how well the model can explain the observed CDS spreads and if it has any predict
The purpose of this qualitative study was to research how people's experience of having a sibling with an autism spectrum disorder affected their upbringing. We held six semi-structured interviews where we examined three different aspects of the participants’ lives in regard to their upbringing and sibling. 1: Their relationship with their sibling. 2: Their role in the family. 3: What kind of

This thesis aims to explore the possibility of using deep learning techniques to mine opinions on Twitter, with the objective to predict the political opinion distribution in Sweden. Different methods of gathering and annotating training data are evaluated to achieve accurate and reliable predictions. The models are quite successful at predicting test data, achieving F1-scores in the range of 70 %
Despite a global increase in gender equality, intimate partner violence (IPV) still plagues all nations. Moreover, IPV is still a heavily stereotyped crime where women are victims and men are perpetrators. Due to the gendered nature of IPV, information that either conforms or deviates from gender expectations can change the perceptions of perpetrators and victims of IPV. The present study investig
