Integration of fluctuating renewables like wind and solar power is nowadays a hot topic, but this comes at a cost of decreased stability of the power system. The deterioration often translates into so-called spikes and drops in the electricity spot price, very large (even extreme) deviations from the regular spot price, followed by a reversion to roughly the original level a few days later. We use
Fortuna’s Guises: Fortune, Misfortune, and Risk in Early Modern Sweden. This dissertation explores learned conceptions of uncertainty and risk during the period stretching approximately between 1560 and 1720. Previous historical overviews of the ideas about risk hold that pre-industrial societies viewed all worldly happenings as emanations of God’s will or other forces lying beyond human control.
To study and compare the safety of intersection, traffic scientists today typically manually monitor the intersection during several days and count how often certain events such as evasive manoeuvres occur. This is a laboursome and costly procedure. The aim of this thesis is to provide tools that can reduce the amount of manual labour required by using automated video analytics. Two methods for cr
A sustainable development was defined by the Brundtlandscommission for the United Nations Conference on Environment and Development as "... a development that meets present needs without compromising future generations to meet their own needs". The definition includes a broad consideration of economic, environmental and social aspects. The definition thus creates a good example of the
Enteric neuropathy describes a disease of the bowel caused by anomalies in the enteric nervous system. Patients suffering from this disease have symptoms including nausea, vomiting, diarrhea and pain. As enteric neuropathy is not well understood yet, its diagnosis is a non-trivial task. Research on the enteric nervous system is needed in order to gain a better understanding of this disease, makin
I en tid med återuppbyggnad av svenskt totalförsvar efterlyser olika aktörer ytterligare kunskap om civilsamhällets frivillighet. Den tidigare forskningen om frivillighet inom det här området saknar ett djupare individperspektiv kring hur frivillighet upplevs av den civila frivilliga, i förhållande till plikt, ansvar och krav. Syftet med denna fallstudie är därför att med kulturanalys fördjupa kunIn a time of reconstruction of the Swedish total defence various actors seek more knowledge about volunteering within the civil society. Previous research on volunteering in this area lack deeper micro perspectives on civil experiences of volunteering in relation to duty, responsibility and demands. Therefore, the purpose of this case study has been to deepen the cultural analytical knowledge of t
European environmental policy has in the recent years become more and more prominent, and with the European Commission launching the European green deal, environmental policy has become a part of the centre stage of European policy. When looking to decarbonise the economy natural gas becomes a favourable solution. However, natural gas is not without a problem i.e., natural gas is still a fossil f
In this master thesis it is investigated where the housing shortage that Sweden faces in 2003 comes from. Starting from two alternative scenarios, a scapegoat is looked for: either the industry is responsible for lowering the supply of housing by increasing the cost of dwellings through illegal cartel agreements, or the state is to be blamed for distorting market forces through an inadequate housi
Populärvetenskaplig sammanfattning: Jordens klimat står under ständiga variationer och förändringar, och det är inte alltid lätt att sära på orsak och verkan bland den mängd av faktorer som styr klimatet. För att kunna reda ut ursprunget till de förändringar som sker, måste de bakomliggande processerna vara väl kända. Sedan är det möjligt att genom matematiska modeller uppskatta de individuella prSeveral studies have analysed the relationship between Normalised Difference Vegetation Index (NDVI) and radiative surface temperature. A main goal for most studies have been to find the best method for carrying out land cover classifications and to study land cover changes, based on a combination between the two parameters. Since atmospheric components have a significant influence on both paramet
The Naqshbandi-Haqqani Sufi order has spread throughout the world extensively since it was founded in 1973 by its Sheikh Muhammad Nazim Adil al-Haqqani. The present thesis analyses one local branch of that order in Eastern London within a theoretical framework of New Social Movements, as formulated by the Italian sociologist Alberto Melucci. A general picture of Muslim presence in Britain is given

Visual inspection in order to assure quality control is a challenging field that is attracting increasing interest after a long period of silence due to the trust and hope in computers and automation. Human visual inspection is however a challenging area as it requires the designer of the system to take in to account demands and limitations of technical, economic and psychological nature. This st
When China opened it borders in 1979, the country suffered from a severe brain drain as its most talented students left the country to take advantage of educational opportunities abroad. However these emigrant engineers, known locally as "sea turtles" or Chinese returnees, have become a valuable asset for Zhongguancun Science Park. The authorities for the high-tech park are now adopting
Sammanfattning Syftet med denna uppsats är att söka svar på vilka analytiska verktyg som krävs för att förstå villkoren för mänskligt handlande. Min tes är att den diskursteoretiska epistemologi som kommit att dominera samtida feministisk forskning - i uppsatsen representerad främst av Judith Butler - inte tillhandahåller dessa analytiska verktyg. För att pröva denna tes har jag intervjuat fem he
The progress made in the field of patents on pharmaceuticals the last fifteen years, has been of continuous change and adaptation. From the introduction of the TRIPS Agreement in 1995, where patents on pharmaceuticals became a necessity for all Member States of the WTO, to today, where a ratification of the TRIPS Amendment is ongoing, and might be a mean to enhance access to medicine for all peopl
Weichselisens avsmältningsskede i Skåne var mycket komplicerat, vilket har föranlett en stundtals svårtolkad glacialmorfologi. I de norra och centrala delarna av Skåne retirerade isen mot norr och nordost, samtidigt som södra Skåne och Danmark berördes av lobformade isframstötar från en baltisk isström från söder- och sydost. Sedan länge har forskning pågått för att finna lösningen på isens rörelsThe deglaciation of the Weichselian ice sheet was very complicated and the resulting landscape has been perplexing different researchers throughout the 20th century. In the northern parts of Scania, the ice sheet receded towards north and northeast, while a dynamic ice stream with fast flowing ice influenced southern Scania and Denmark. The earlier researchers have mainly focused on striae, the di
Detta arbete har som sitt främsta syfte att belysa lagregleringen samt avsaknaden av lagreglering gällande beslutanderätt vid gemensam vårdnad. Behandlingen av ämnet inriktar sig på den nuvarande lagstiftningen och därtill föreslagna åtgärder för att förbättra möjligheterna för föräldrar med gemensam vårdnad att bibehålla den gemensamma vårdnaden, trots att det råder meningsskiljaktigheter i en viThe aim of this thesis is to clarify the legal situation regarding Swedish custody law. It also discusses the absence of legal rules in terms of right of decision in joint legal custody. The essay is structured to focus on the current legislation and also to argue proposed measures to improve the opportunities for parents with joint legal custody to maintain the joint legal custody even though the
This thesis aims at presenting the differences and similarities between the Swedish and Canadian legal system, by means of search and seizure regulations. In doing this I hope to provide the readers, whether it is a Swede or a Canadian, with a perspective on their own legal system. In the limited time and space offered for the completion of this thesis, I had to choose one specific area of law to
The aspartic protease cathepsin D, a poor prognostic indicator of breast cancer, is abundantly secreted as procathepsin D by human breast cancer cells and self-activates at low pH in vitro, giving rise to catalytically active cathepsin D. Due to a lower extracellular pH in tumor microenvironments compared to normal tissues, cathepsin D may cleave pathophysiological substrates contributing to cance
The aim of this multicenter study was to investigate whether a computer-assisted diagnosis (CAD) system could improve performance and reduce interobserver variation in bone-scan interpretations of the presence or absence of bone metastases. Methods: The whole-body bone scans (anterior and posterior views) of 59 patients with breast or prostate cancer who had undergone scintigraphy for suspected bo
