This thesis is performed in collaboration with Kraftpowercon AB in Surte, Sweden. Focus has been on to identify the powerlosses in one of Kraftpowercons halfbridge DC-DC converters. First theoretical calculations are made, the calculations is verified with measurements of six different operation modes. In a later stage, methods like soft switching and synchronous rectifying are proposed to increase the efficiency for the converter. To achieve softswitching for the halfbridge, the LLC resonant converter topologies are implemented and examined.

This degree project aims to investigate the potential and possibilities for conceptual energyanalyses in the early stages of the design process. Many key decisions are made in theearly stages of a project regarding the shape and orientation of the building. Conceptualenergy analyses can provide the architects with insight regarding different design option?srelative energy performance.As the demands for more sustainable buildings increases, so does the need for earlyenergy analyses. Performing analyses in the early stage requires many assumptions andguesswork which could lead to a large margin of error.The offering from Autodesk is a module in Revit Architecture/MEP and the stand aloneprogram Project Vasari (under development).

This report is going to be focusing on the development of a promotion page and login system for the web production company Adoreyou. The promotion page and login will be parts of a new taxi application for iPhone that lets the customer book a taxi and drivers manage the requests from the customers.Taxi application?s that let customer?s book trips are nothing new but they are constantly being explored and developed. The most common practice is to let the customer fill in from what address he or she wants to be picked up and to where he or she wants to be taken. Then the price is set in the application depending on the distance and most likely other factors like weekday and time.

It is common that patients experience emotional reactions as agony and anxiety after an acute myocardial infarction. Only a few studies related to the support in the acute stage have been made. The aim was to describe how nurses declared their support to patients with acute myocardial infarction in the acute stage. The used method was semi structured interviews with seven nurses in an Emergency ward in South of Sweden. The material was processed and analysed with inspiration from content analysis and produced two main themes.

Peat litter has been used in animal houses for a long time. Because of its good ability to absorb liquid and nutrients from the manure it can create a dry surface for animals and a valuable manure product. Through changes in agricultural practises the use of peat litter has diminished and is to a great extent replaced by straw, sawdust and cutter shavings although Sweden is rich in peat-findings. The aim of this work was to summarize the presented knowledge about the used of peat litter, techniques, advantages and disadvantages and to compare with other commonly used litter materials. Articles on peat litter have been searched for in magazines, databases and books at SLU library. Visits to peat industries, interviews with peat producers and with peat researchers contributed to the material. Peat is not a uniformly material.

Syftet med studien är att undersöka makroekonomiska variablers effekt på Dow Jones och OMXS30, med hjälp av en lämplig ekonometrisk modell. Vidare är syftet att analysera möjligheten för börsprognostisering och analysera om denna möjlighet är lika stor för Dow Jones som för OMXS30. Detta kommer att ske genom att undersöka motsvarande variabler för respektive lands aktieindex. Variablerna arbetslöshet, ränta och oljepris visade sig inte ha någon signifikant påverkan på varken Dow Jones eller OMXS30. Det visade sig dock att aktieindexen reagerade på samma sätt, för respektive lands variabler..

This two years master's thesis examines the experience of children who read to a dog. The theoretical framework is inspired by sociocultural theory developed by Roger Säljö and the concept carnival inspired by Mikhail Bakhtin. The sociocultural theory has been chosen because it emphasizes the role of practice, instruments and communication in learning and the concept carnival has been chosen to analyze the experience of reading to a dog.The method used is qualitative interview and observation. A total of eight interviews and two observations when children read to a dog have been collected. One interview is with a teacher and seven interviews are with the children (six children participated and one child was interviewed twice).

In search of a stage language that resonates in historical disciplines, I have explored the possibility to expand my performing arts through the language of Indian classical Odissi, through different forms of storytelling. In my work I have focused primarily on two projects inspired by the original scripts of Macbeth by William Shakespeare and Breaking Bad by Vince Gilligan. I have outlined examples of methods and techniques used in the process.The work also shows how Odissi has evolved from a religious and philosophical tradition of temple dance; into modern stage theatre performance.The work aims to connect Odissi with western performing art. In this process I have been using my own knowledge about Odissi as a tool in combining both the traditions, a fusion in action.I will physically examine the artistic idiom, the characteristics, the actions and deeds found in stylized Odissi imagery and symbols, traditionally used to embody mythological and epic stories. A rendezvous between East and West.

Color management has become more common now than ever in the graphic trade. Calibration andcharcterization are words that are mentioned very often when it comes to controlling colors andwhen you want a printed picture to look the same as an original photograph. The problem is thatthere are not so many people that has the knowlegde about this subject. Even if a printer supportscolor management it is not sure that the result is going to be satisfied and that a printed picture isgoing to look the same as the original.The printers which were used were Hp DeskJet 970 Cxi, Xerox Docu Color 12 and AgfaChromapress 50i. The theory of color, colour management and the equipment which were usedare described in the first stage.

During the last decade of the twentieth century both ?manhood? and gender studies seems to have undergone changes. With the field of masculinity and the critical studies of men, added as ?subsections? of broader gender studies, new knowledge has been produced to better grasp the production of gender and power relations of patriarchy. During the same decade as the ?metrosexual? first appeared of the urban stage, acts of homophobia and attitudes towards ?manhood? seems to have changed.

This thesis investigates the communicative role of scenography in the performing arts for children, with an aim to make the readers understand the ways in which a set design can be optimized so that a young audience can be able to interpret the play and its message.The art of scenography is complex and includes many elements. The research questions can therefore be grouped into three clusters: one artistic oriented (How does the scenographic process work and what is its relation to the scenic piece at large? In which ways may scenography be used to support the desiderate interpretation?), one audience oriented (Which work processes enhances the chances of creating dramatic art that is perceived as meaningful to the audience? On what premises can the semiotics of theatre be used in the performing arts for a young audience?) and last a cluster that focuses on Den magiska cirkeln (The Magic Circle) by ung scen/öst (What is told in the show and how is this portrayed in the scenography? Who is in the target group, and does the audience get the feeling of the performance as intended?).Den magiska cirkeln is used as a case study in the thesis in order to reflect the theoretical material. Methods in the case study includes performance analysis, a survey completed by 178 people in the audience and an interview with scenographer Anna Dolata. 14 performing analyzes of Swedish children?s theatre shows have been made in addition to the case study.The thesis analyses and compares two work logics; the internal logic and the external logic, and it is shown that meaningful interpretations are likelier to happen with an external logical point of view.

Background: War-related amputations are represented by a unique group of patients because of the wounds complexity and scope of several serious injuries. To prevent and avoid care suffering and suffering of the patient, this study focused on the nurse's way to manage and identify the needs of this unique group of patients who have suffered from war-related limb loss. To undergo a traumatic amputation is a big change for the victim, and the nurse has an important role in responding to the patient and their needs Aim: To illuminate nursing care of patients with war-related limb loss. Method: The chosen method was a literature review. The data consisted of nine qualitative and three quantitative studies.

Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

The aim of this thesis is to examine how thesauri constructed with latent semantic indexing LSI are performing when used for query expansion. There is a well-known problem with synonymy in information retrieval and one solution to this problem is to use a thesaurus. In this thesis thesauri are created automatically to find statistically related words and not only synonyms. LSI is a method that uses singular value decomposition SVD to reduce dimensions in a matrix and find latent relationships between words. We constructed nine thesauri and used them for query expansion in a Swedish database, GP_HDINF.
