Learning robot motions from demonstration requires models able to specify vector fields for the full robot pose when the task is defined in operational space. Recent advances in reactive motion generation have shown that learning adaptive, reactive, smooth, and stable vector fields is possible. However, these approaches define vector fields on a flat Euclidean manifold, while representing vector f

Reinforcement learning with sparse rewards is still an open challenge. Classic methods rely on getting feedback via extrinsic rewards to train the agent, and in situations where this occurs very rarely the agent learns slowly or cannot learn at all. Similarly, if the agent receives also rewards that create suboptimal modes of the objective function, it will likely prematurely stop exploring. More

Reinforcement learning (RL) has demonstrated its ability to solve high dimensional tasks by leveraging non-linear function approximators. However, these successes are mostly achieved by 'black-box' policies in simulated domains. When deploying RL to the real world, several concerns regarding the use of a 'black-box' policy might be raised. In order to make the learned policies more transparent, we

The purpose of this study was to illustrate how youth crime is constructed by three different political parties in Sweden; Moderaterna, Socialdemokraterna and Vänsterpartiet. The data in this study consists of several official political documents such as interpellations, motions and proposals. The documents were analyzed using perspective analysis, which stems from the social constructionist persp

Finding vulnerabilities in open source software is an important part of software security. Software security is in turn a vital part in risk management and making risk assessments. The purpose of this thesis is to help organisations make decisions about vulnerabilities they have in their software programs by helping them make their own risk assessment. Our research uses the Common Vulnerability Sc

This master thesis is performed in collaboration with Orkla Foods Sweden AB. The aim with this study is to investigate and compare nutritional contents in processed and homemade foods by investigating three selected ready meal products from the product range of Orkla Foods; meatballs, potato mash and pasta bolognese. This originates in a general perception that foods produced in a large-scale indu

Increasing waste electrical and electronic equipment (WEEE) has become a global issue that raises social and environmental impact concerns, and recycling and using recycled materials is proposed by policymakers and academics as a solution. Nevertheless, barriers still exist and result in low collection and recycling rates and underdeveloped recycling markets. This paper aims to first understand ho

Att utbilda och fortbilda sina anställda är en viktig process för företag. Det krävs mer och mer för att företag ska hålla kvar sina anställda och möjligheten att utvecklas och fortbildas är något anställda ser positivt på. När samhället har digitaliserats så har processerna förändrats och digitala systemstöd har blivit en vanlig del av HR-avdelningens arbetsuppgifter. Ett systemstöd som används f

This thesis used the qualitative textual analysis research method to study the blog content and comments of the DiDi Hitch algorithm controversial published by China News on Weibo. The purpose was to explore netizens’ views on gender bias and conflict in artificial intelligence consumption scenarios, as well as the drawbacks of DiDi Travel when adapting to artificial intelligence algorithms. In th

Aim: The aim of this study is to explore why German millennials use the green search engine Ecosia, as the organisation is experiencing considerable growth in Germany. Theoretical Perspectives: This thesis adopts well-established theories such as the Theory of Planned Behaviour, the Value-Belief-Norm Theory, and the Social Influence Theory. Moreover, the theoretical perspective consists of the Mu

Under 2020 och 2021 har en stor del av organisationer i Sverige och runt om i världen tvingats lägga om sin verksamhet till arbete på distans till följd av Covid-19 pandemin. Detta har lett till nya utmaningar inom inte minst informationssäkerhet, där policys och riktlinjer i många fall varit anpassade för arbete i organisationernas lokaler. Då den största risken inom informationssäkerhet är den m

This study investigates the cyber security threats and risks that are associated with forced teleworking during the period of Covid-19, when organizations have been forced to telework. Three different main aspects from two theories have been crucial when investigating the threats and risks associated with forced teleworking, which are the Social, Technical and Risk Tolerance aspects. This study

The overall purpose of the present thesis is to explore how participatory development architecture and the good governance principles of cooperation and consensus have depoliticised disability as an issue and have re-shaped the discourses and actions of organisations of and for disabled people in Georgia. Through the lens of the theory of post- politics, the research analyses the application of go

Bakgrund: På grund av otillräcklig stöttning och anpassning inom grundskolan når mindre än hälften av barnen med autismspektrumtillstånd (AST) kunskapsmålen. Internationella erfarenheter och studier av arbetsterapeutiska interventioner för att stödja dessa elever visar på positiva effekter avseende aktivitetsutförande och skolresultat. I Sverige är dock användningen av arbetsterapeutiska interventBackground: Due to insufficient support and adaptions in compulsory school, less than half of the children with autism spectrum disorder (ASD) reach their academic goals. International experiences and studies of occupational therapy interventions for these children show positive effects regarding occupational performance and school results. In Sweden, however, the use of occupational therapy inter

Den här uppsatsen beskriver och analyserar den gränsdragningsproblematik som kan uppstå när enskilda ingår avtal med det allmänna. Genom praxis som behandlas inom områden så som avgiftsskyldiga högskolestudenter, barnomsorgsavgifter, parkeringsavgifter och patientavgifter framgår det att rättsområdena ofta är sammanflätade och består av olika delar som samspelar med varandra. Uppsatsen ger en kortThis thesis will describe and analyze the boundary problems that can arise when individuals enter into agreements with the public authorities. Precedent cases dealt with in areas such as university student’s tuition fees, childcare fees, parking fees and patient fees show that legal areas between public law and civil law are often intertwined and consist of different parts that interact with each

Denna uppsats är en kvalitativ studie med syfte att undersöka kvinnliga kreatörers upplevelser av att erbjuda sexuellt innehåll på den digitala plattformen OnlyFans. Studien undersöker huruvida olika faser av en avvikarkarriär kan urskiljas i processen till att bli en etablerad kreatör på plattformen samt om kreatörerna upplever stigmatisering av sitt arbete och hur de i så fall hanterar stigmat.

Bakgrund: COVID-19-pandemin har lett till stora förändringar i samhället där hälso- och sjukvården blivit särskilt drabbade. I tidigare studier har arbetsterapeuter rapporterat en ökad arbetsrelaterad ohälsa och stress på grund av brister i den psykosociala arbetsmiljön. Det är därför viktigt att undersöka hur arbetsterapeuter upplever sin psykosociala arbetsmiljö under pågående COVID-19-pandemin Background: The COVID-19-pandemic has had several consequences on society where the healthcare has been especially affected. In previous studies occupational therapists have reported increased work-related illness and stress due to cause by defects in the psychosocial work environment. It is therefore important to investigate how occupational therapists’ experiences their psychosocial work environ
