In the beginning of 2020 the world experienced the most severe pandemic since the last globalization wave. In Scandinavia the COVID-19 outbreak was countered with similar aims but with different measures. When Denmark imposed extensive restrictions Sweden took a completely different path. This study investigates the reason why seemingly equal countries opted such different crisis management strate
In the current development of coherent optical communication systems, nonlinear noise is considered to be the ultimate bottleneck when extending the transmission length. In this report we suggest a nonparamter digital signal processing scheme to extend the transmission length of a fiber link. The processing scheme was enabled by machine learning, implemented to compensate nonlinear noise in a comm
I detta examensarbete har man undersökt hur olika renheter på vatten påverkar kvaliteten på vattenbaserade färgprodukter. Man har använt sig av två olika renade vatten och kranvatten som kontroll. De renade vatten som användes var avjoniserat vatten och destillerat vatten. Avjoniserat vatten renas genom filtrering och destillerat vatten renas genom kokning och uppsamling av vattenångan. KvaliteteIn this project the effect different water qualities had on water-based paint products were investigated. Tap water was used as a control and deionised and distilled water were used to determine whether the water purity had an impact on the quality of the finished paint products. One intermediate and five finished products were used to investigate the effect of water purity. The intermediate was
Our aim is to use clustering algorithms in order to compute support and resistance levels within an intra-day trading setting. To achieve this we use a tick data set from the EUR-USD exchange market during 2019 as a measure of market activity. Both the Gaussian Mixed Model (GMM) and an altered form of Kmeans clustering will be used as clustering methods where each method will be evaluated using a
This thesis regards the study of cellular automata, with an outlook on biological systems. Cellular automata are non-linear discrete mathematical models that are based on simple rules defining the evolution of a cell, depending on its neighborhood. Cellular automata show surprisingly complex behavior, hence these models are used to simulate complex systems where spacial extension and non-linear re
Titel Förändringsledning inom en svensk myndighet - En kvalitativ studie av Arbetsförmedlingens pågående förändringsarbete Författare Charlie Hedhav Handledare LTH Carl-Johan Asplund Bakgrund Arbetsförmedlingen inledde 2014 ett förändringsarbete. Organisationen hade länge kämpat med låga förtroendesiffror från allmänheten och de anställda upplevde sig vara detaljstyrda. Med det nya förändrinTitle Change Management within a Swedish Authority – A qualitative study of Arbetsförmedlingen’s ongoing change journey Authors Charlie Hedhav Supervisor LTH Carl-Johan Asplund Background In 2014, the Employment Service, Arbetsförmedlingen, started a change journey. The organization had struggled with a bad public reputation and the employees experienced micromanagement. With the new change p
Research on ultrafast dynamics in atoms and molecules requires short pulses. In order to resolve processes taking place on a femtosecond timescale sufficiently, these pulses require a duration on the attosecond time scale. This thesis is about the generation of such attosecond pulses via high harmonic generation (HHG) in argon gas by a terawatt infrared (IR) laser source. The pulses are applied in
The aim of this thesis is to discover how ideals about women’s workers’ identity regarding to bildning (workers’ education), class and organization are produced and constructed within the Swedish socialist journal Morgonbris (i.e. Morning Breeze) 1904–1916. The journal was first published within the labor union of women in Sweden, and was later on intertwined with the Social democratic women’s lea
Abstract Our society is facing a changing demographic with an increasing proportion of the elderly, and in addition there is an increased need for housing adapted for this older population. There is much in the physical environment that can be adapted to meet the needs of the coming generation of elderly people. The need of healthcare for today’s elderly will look different from previous generat
Characterization of a gene associated with polar growth in Streptomyces venezuelae Bacteria display a variety of shapes which includes spheres, rods, spirals etc. This variety of cell morphology is determined by the cell wall and the cytoskeleton, and by mechanisms that control growth, cell division and cell wall synthesis for example in response to the surrounding environment. Streptomyces spp.
Identifying new targets for cancer treatments Cancer continues to be one of the leading causes of mortality worldwide, responsible for millions of deaths each year. As our knowledge regarding the biological systems involved has grown, incredible progress has been made towards the development of effective new treatments. We now know that targeting of cells responsible for promoting cancer growth c
Samma mikroorganismer som äter upp Titanic kan hälpa oss att rena smutsigt vatten. Vid en soptipp utanför Hässleholm står det idag en pilotanläggning som ska rena lakvatten från tungmetallar. Experimentet använder biologiska processer för att få bort ämnen som inte hör hemma i naturen. Studien relaterar till riksdagens miljömål om en Giftfri miljö och har hittils vissat lovande resultat. Många kAnaerobic treatment of landfill leachate using sulphide precipitation was tested at pilot scale for the purpose of heavy metal removal. The emission of leachate is heavily regulated by Swedish authority and the overall concentrations of heavy metals is expected to rise as landfills contain less organic matter. The studied landfill site, located in southern Sweden, needs a robust and economically v
Bolivia är ett av de fattigaste länderna i Sydamerika och landet lider av ojämn social och ekonomisk utveckling. Bolivia har stora sötvattenresurser per capita (28 300 m3), jämfört med 17 600 m3 per capita i Sverige. Men tillgången är emellertid inte jämnt distribuerad över landet. Istället återspeglar tillgången på sötvatten landets karakteristiska geografi där östra Bolivia får mest nederbörd, uThe objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. The hydraulic conductivity (Kfs) was obtained from seven in situ measurements of infiltration rate (I) performed by Double Ring Infiltrometer (DRI) test. These seven values were compared to the hydra
In order to make correct decisions, information is needed. Information must be correct and founded on facts for the analyst to make correct decisions, to anticipate the actions of an op-ponent and prevent espionage against our nation. The question at issue in this paper is whether the importance of HUMINT has decreased with the rapid progress of technology and the availability of other types of i
Pregnancy decisions are notably connected to maternal well-being, particularly for groups disproportionately affected by unplanned and unwanted pregnancies such as adolescents. Midwives are health professionals most likely to care for a pregnant adolescent in a public healthcare setting and spend the most time with her during her pregnancy. However, there are no studies in Peru of the perceptions
The thesis analyzes how two NGOs working with female sex workers in India, Purnata and National Network for Sex workers, define and construct the problems they are trying to solve by using Carol Bacchi’s ‘What’s the problem represented to be?’ approach on discourse analysis. By analyzing written material from both of the NGOs, posts from their Facebook pages, and an interview with an employee from
Women in rural areas of South Africa battle with many structural issues, including unemployment, education and accessibility to health services, greatly delimiting family planning. However, socially constructed and internalized gender norms pose an additional and potentially greater barrier to family planning in traditional and patriarchal settings. This thesis aims to contribute to the growing re
Environmental Education [EE] was created in the pursuit of providing specific targets to promote environmental, knowledge, attitudes, skills, participation and creating the societal shift. India was perhaps one of the first nations to have internalized EE in primary school curriculums, however, its application is still far from flawless. Teachers have often been observed as they take a central rol
The gendered nature of impacts from climate change and disasters has become increasingly apparent. As such, this thesis analyses gender mainstreaming at the Development Cooperation Section of the Swedish Embassy in Bangkok with specific reference to its climate change and disaster risk reduction contributions in the Asia-Pacific region. Gender mainstreaming is contextualised within a wider theoret
