Hemodialysis is today the main treatment used for patients with renal impairment, a serious medical condition. Hemodialysis treatment handles a very delicate system which is why it is of the utmost importance that the dialysis machine has got a reliable safety monitoring system that can detect severe complications during treatment. A new such system is currently under development at Gambro, Lund,

Syftet med föreliggande studie var dels att beskriva den grupp som spelar massiva onlinespel (MMO), dels att undersöka vilka faktorer som har betydelse för ett eventuellt problematiskt datorspelande. Analysen baserades på 429 svar från deltagare som fyllt i en webbenkät bestående av flervalsfrågor fördelade på skalorna prestation, social interaktion, självreaktiv förväntan, flow, bristfällig självThe aim of this study was to provide a description of the Swedish massively multiplayer online (MMO) community, and to investigate factors pertinent to problematic gaming. The analysis was based on 429 answers from a multiple-choice web-based survey with questions spread across the following scales: achievement, social interaction, self-reactive outcome expectations, flow, deficient self-regulatio

In this thesis, the impact of unknown parameter estimation in the case of the volatility parameter in the Black-Scholes model on hedging is investigated. The objective is to develop a systematic and robust model of hedging to challenge the conventional delta and improved mean-variance hedge, and hopefully improve upon risk assessment values. The proposed algorithms were tested in situations of unc

Wind energy production is a section that became bigger and bigger thanks to the interests in finding new ways to produce energy that do not involve fossil fuels because of environment concerns, because of their costs and because of their limited amount. Even though wind energy was exploited also in the past, for example in wind mills, it is with wind turbines that all the problems affecting these

The day of bud burst (DBB) of different tree species are known to be affected by factors such as growing degree days and temperature. In this paper a two state Markov chain is used to model DBB for birch. The model is fit using logistic regression and LASSO regularization is used to evaluate which of many potential factors best forecast DBB. Data of birch from both Finland and the United Kingdom i

This master thesis describes how to compensate for the compliance of the Gantry-Tau robot. The main reason for this is to improve the performance of the robot. The compliance is modeled as nine springs, one for each cart and each link. The model seems promising but has only been tested in homing position of the robot but shows a positive result in decreasing the compliance. External control of the

I uppsatsen undersöks kunskapsuppfattningar i läromedelsannonser inriktade mot högstadiet, gymnasiet eller motsvarande. Det resoneras också kring hur forskning teoretiskt kan förhålla sig olika pedagogiska traditioner.

Taking a deeper look into Dorothea Tanning’s painting Insomnias by investigating the use of medium as a physical entity applied to the canvas, that create illusions. The materiality is brought into focus do it its diverse range in techniques as well as the use of the medium’s viscosity, creating effects only achieved thought experiments. The painting lends itself to the discussion on how the forma

Positiva psykologiövningar har påvisat goda effekter i strävan efter att optimera och främja människors välbefinnande. Speciellt stor potential har tacksamhetsövningar, då deras effekt till skillnad från många andra övningar inte tappar lika mycket allteftersom tiden fortlöper. Pilotstudien gick ut på att kartlägga effekterna av tacksamhetsövningar så som 3 blessings. Syftet med detta var att se o

Knowledge is an element considered by common consent as strategic for innovation but at the same time it is quite confusing and ambiguous. New approaches of management are less top-down orientated and more dialogical: they can enhance a successful transfer of tacit knowledge. Small companies interpret and transfer tacit knowledge in a “silent” way, namely the methodologies to transfer it are embe

The purpose of this master’s thesis was to examine existing augmented reality technologies and develop an application for Windows phone. The goal with the application was to find new ways to use augmented reality technologies together with public transport. The end user would use the application to search for and find new journey options. The development process consisted of four steps – investig

I en värld där många fler människor ska leva på allt färre resurser har matavfall hamnat i ett stort fokus. Svinnet innebär att hela produktionen har gått förlorad. Det är ett ekonomiskt bortfall för företag men även för samhället i stort. Dessutom orsakar hela livsmedelskedjan miljöpåverkan, inte minst från ett klimatperspektiv. De olika aktörerna försöker självklart minska sitt eget svinn men efIn a world where more people must survive on fewer resources, food waste has become greatly focused. Waste means that the entire production has been unnecessary. It is an economic loss for a company but also for society at large. Moreover, the food chain causes an environmental impact, not least from a climate perspective. The various actors certainly try to reduce their own losses but because con

The increased possibilities for geographical separation of the production process have given rise to a growing interest for trade in intermediate goods in the international trade literature. Thanks to trade in parts and components, but also in services and other immaterial products, developing countries have been able to enter the global trade scene to a greater extent than before. This paper anal

Title: The use of art for branding purposes - A study of Louis Vuitton’s art collaborations Louis Vuitton’s creative director, Marc Jacobs, personally describes the fine arts as being higher up in the social hierarchy than fashion. After all, it is known as the ultimate luxury item. This essay will explore the way that the brand uses art in various ways as a means of branding. After extensive res

The initiation of leaf and flower primordia in plants occurs in the shoot apical meristem and results in visible large–scale regular patterns of organs. It has previously been proposed that the initiation of new primordia is triggered by the plant hormone auxin by a mechanism that is confined to the outermost epidermal layer of the meristem. Recent experiments suggest that the genes KANADI (KAN)

The aim of this study is to explain what a Pro-ana blog is and from an identity perspective examine the level of significance these blogs have for the users. The study is based on five blogs and its last fifteen posts. To analyse these we used a qualitative method in terms of text analysis on the basis of a social constructionist theory. The results showed us that Pro-ana is seen as a lifestyle by

Because of the industrialization in the late 19th century the amount of waste from private individuals and industries rose steadily as the standard of living improved and consumption grew. Consequently several landfills where everything from household garbage and construction waste, industrial waste and chemicals was deposited developed in each municipality. When legislation concerning landfills g

The aim of this study is to get closer to the complex cultural expression of performance art through its relation to the body and the phenomenon of presence. The investigation is based upon two analysis of performance artworks such as the virtual performance installation Telematic Dreaming (1992) by Paul Sermon, and the live performance The Artist is Present (2010) by Marina Abramovic, which is a
