Two main topics are considered in this thesis: Machining with industrial robot manipulators and optimal motion control of robots and vehicles. The motivation for research on the first subject is the need for flexible and accurate production processes employing industrial robots as their main component. The challenge to overcome here is to achieve high-accuracy machining solutions, in spite of the
Force sensing provides robots the capability to accomplish tasks where physical interaction with the environment is required, such as assembly. Small position uncertainties can then be corrected for by sensing the contact forces. This thesis considers the problem of force-controlled assembly, including how tasks can be specified in a simple and intuitive way and how robust task execution under unc
The purpose of this study was to explore neuroretinal transplantation in a large animal model of severe retinitis pigmentosa and to establish graft development, long-term survival, graft-host integration, and effects on the host retina. Methods Rhodopsin transgenic pigs, aged 6 months, received in one eye a fetal full-thickness neuroretinal sheet in the subretinal space by means of vitrectomy and
Although Moral Foundations Theory claims that the foundations of morality are universal, there are still few studies addressing it through non-English measures. In the current research, 540 persons filled out a Swedish translation of the Moral Foundations Questionnaire, and 332 of them filled out political attitude measures. Confirmatory factor analyses suggested that the fit of the five-factor mo
Information technology is a vital driver in today’s business environment. Recent developments of IT have facilitated for the relatively easy creation of markets on the Internet, so called B2B-marketplaces. However, judging from the survival rate of B2B-marketplaces (5 to 10 per cent), it seems like B2B-marketplaces are doing something wrong. This paper scrutinises several theoretical frameworks re
Abstract in UndeterminedThe use of a polar diagram method for describing and evaluating the machinability ofInconel 718 was explored. Five key parameters of the work material, representing themechanical and physical properties, which have the strongest influence on its machinability,were employed in the diagrams. These five parameters were integrated into asingle polar diagram, used to describe th
Uppsatsen har till syfte att beskriva och analysera vilken funktion förvaltningsrevisionen fyller i aktiemarknadsbolag som tillämpar Svensk kod för bolagsstyrning, samt ge förslag på hur förvaltningsrevisionen bör förändras i dessa bolag. Uppsatsen är till största del deduktiv då den tar sin utgångspunkt i teorier. Vidare grundas uppsatsen på en kvalitativ metod i form av semistrukturerade intervj
The case of Bertil Ströberg has repeatedly been called one of Sweden's most remarkable criminal cases. The indictment against Ströberg from 1983 claims that he committed grave espionage against Sweden on behalf of Poland. Ströberg says that he is innocent of the crime, and fought until his death to get his case reopened in the Supreme Court. That Ströberg would be innocent is explained by the
In today's digital era, where personalized experiences have become crucial to consumer interactions with brands, the balance between personalization and privacy remains a complex and evolving challenge. Despite the recognized benefits of personalization in driving consumer spending, concerns about privacy and data security persist among individuals. This study addresses the "personalizati
Amidst global efforts to address pressing environmental challenges and achieve the Sustainable Development Goals, education for sustainable development emerges as a pivotal tool for fostering societal transformation towards a more sustainable future. Within this context, competence frameworks serve as essential guidelines for integrating sustainability into education. This research investigates th
Purpose: Study the relationship between stock returns and GHG emissions regarding a risk premium related to greenness. This by using GHG emissions estimated by Bloomberg rather than companies self-reported estimates. Methodology: The study conducts a time-invariant model by cross-sectional OLS regression to estimate the risk premium for greenness. Weighted Least Square regression (WLS) to estima
I Sverige finns en väletablerad marknad för handel med barn för sexuella ändamål. Det är dock väldigt få anmälda brott som leder till åtal eller fällande dom. Detta visar på att barn som faller offer för människohandel inte innehar fullt rättsskydd. Den 1 januari 2020 trädde barnkonventionen i kraft som lag i Sverige, implementeringens primära syfte var att stärka barns rättsliga ställning. SyftetIn Sweden, there is a well-established market for child trafficking for sexual purposes. However, there are very few reported crimes that lead to prosecution or conviction. This shows that children who are victims to human trafficking do not have full legal protection. On January 1st, 2020, the Convention on the Rights of the Child entered into force as law in Sweden. The primary purpose of the im
The elderly population within the European Union is growing where as the amount of caregivers is not. The objective of the NavMem project is to make older citizens more self-sufficient and confident specifically while traveling on foot. This could potentially lead to a more active and social life while decreasing the need of senior citizen care. With this objective in mind the NavMem consortium ha
