Analys av verkningsgrad för en industriell DC-DC omvandlare

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.

Användning av realtidsdatabas i diagnostiksystem

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.

Talet hos femåriga barn med läpp-käk-gomspalt: En jämförelse mellan internationellt adopterade barn och svenskfödda barn

This retrospective study aimed to examine differences at age fivebetween twenty-six internationally adopted and twenty-six Swedish-bornchildren with cleft lip and palate regarding age of surgery, speech andintervention. Correlation between age of surgery and speechvariables andgender differences was examined. Blind assessment of audio recordedsentence repetition or naming of words was performed by two speechpathologists. Soft palate was closed significantly later for the study groupthan the control group. Age at closure of hard palate did not differ.

Genetiska ultraljudsmarkörer : Hur bör information till blivande föräldrar i samband med rutinultraljudet hanteras?

Objective: The purpose of the study is to explore and illustrate how ultrasound midwives and medical specialist in obstetrics and gynecology believe the information given to parents about the genetic Soft markers should be handled.Design: A quantitative questionnaire study with cross-sectional design. Participants: 44 ultrasound midwives and 37 medical specialists in obstetrics and gynecology.Findings: Most of the participants would like to inform before the ultrasound starts that they will be looking for genetic Softmarkers during the ultrasound. Likewise the majority wanted to inform the parents about possible increases in the risk for chromosomal abnormalities based on findings on the routine ultrasound. There was a difference in frequency between those who responded that they would like to inform before the ultrasound that they will be looking for genetic Softmarkers and those who responded that they believe the future parents wants information before the examination.Key conclusions: It could help health care professionals in their role as information providers if there were common recommendations for the information to be given to future parents about genetic Softmarkers in connection with the routine ultrasound.

Fråga en man istället : En kvantitativ studie om hur könsfördelningen ser ut i SVT 1 Rapport och TV4-Nyheterna.

The purpose of this study was to investigate if female and male reporters and interviewees get the same amount of time in the news feature in the Swedish news programs TV4-Nyheterna and SVT 1 Rapport. The aim of this study was also to investigate if there is a breakdown of the reporting lines between male and female reporters, that is, if they are reporting on various topics. In our study we also determined if the two television channels in any way are different when it comes to gender.Our main theory was that men are overrepresented both among reporters and interviewees and that they are dominant in both hard and Soft news. We thought that SVT 1Rapport would have a better gender balance than TV4-Nyheterna because SVT 1 has been working on gender issues for a long time.We were using a quantitative content analysis to examine the 19:30 news on SVT 1 Rapport and 22:00 news on TV4-Nyheterna for two weeks in November 2010. We examined domestic and foreign news and determined how much time each sex got.

Claw and leg lesions in preweaning piglets : a comparative study of piglets reared on structured polyurethane coating and piglets reared on concrete floors

Floor surface in pig facilities can have an impact on animal welfare and pig health, as it can cause the pig physical damage and thereby increased risk of infectious diseases and lameness. The development of pig housing systems has resulted in a decreased use of bedding. It seems hard to find the optimal floor in farrowing pens, as it must suit both the sow and piglets. The floor friction needs to be adequate to avoid slips and at the same time should the floor be non-abrasive. Abrasions and lesions caused by the floor are not only causing the animal suffering, but are also negative from an economical aspect.

Musik som kommunikation : en empirisk undersökning hur musik kan påverka startblocket av en lektion

Music affects us humans. Marketing has long made use of music as a means to enable customers to identify with a brand, and thus increase sales. The Influence of music is obvious, but can you use this on students, and how effective is it to use in a classroom?I will answer the question: how does Soft music provide reassurance/create a harmoniums learning environment at the beginning of a lesson?By observing how students react and behave to the playing of Soft music. My aim is to create different strategies that teachers can effectively use to get students to ?jump in? to their lessons without wasting 5-15 minutes of class time.Professor Lennart Grosin conducts research into what is in Sweden called PESKO.

Däck-mark Interaktion hos skogsmaskiner

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and Soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Aktinos : genomgång av aktinosproblematik hos nötkreatur

Actinomycosis is a rare, deep-seated infection of the jaw of cattle that include the progressive enlargement of bone structures. It is caused by Actinomyces bovis, a gram-positive rod found as a normal commensal of the alimentary canal in otherwise healthy animals. This paper shortly describes Actinomyces bovis and its ability to cause "lumpy jaw" or actinomycosis in cattle. It will describe its pathogenesis, diagnosis, treatment and some clinical presentations. The incidence of symptomatic actinomycosis infection is quite low in Sweden today.

Prevalens och genetisk karaktärisering av afrikansk svinpestvirus i vektorer och tamsvin i Uganda

African swine fever, ASF, was first described 1921, in Kenya. The virus has thereafter spread through many African countries as well as in Europe, Asia, South- and Central America. The virus is spread via three different cycles, of which one is sylvatic and includes warthogs and Soft ticks. The other two are between domestic pigs and the one most common one is caused by humans, who not always realize the seriousness of precautions. The infection manifests as hemorrhagic fever, but can also be more or less unnoticed. The aim of this study was to use molecular tools to detect and partly genetically characterize ASFV both in Soft ticks and in serum from domestic pigs in Uganda. Comparing viruses detected in ticks with those detected in domestic pigs I also wanted to investigate possible links between the sylvatic and domestic cycle.

Den representativa demokratin och kompetenskraven : En studie av kompetensnivå och kompetenskrav på kommunpolitiker

The local politicians in Sweden are responsible for a great deal of the welfare system why one would assume that there are a lot of demands put on them - demands for certain skills or a certain level of competence. I have in this study tried to find out how the demands on the local representatives concerning the demands for competence and the actual level of competence among the politicians are affecting the local politics. This was done through investigating how the local politicians are perceiving their level of competence and the demands put on them, but also how the employees are perceiving the demands and the level of competence put on the politicians. The study was made in the municipality of Gislaved in Southern Sweden. I was using both quantitative method (an opinion poll among the politicians and employees in the municipality) and qualitative method (interviews with three politicians and three employees and literature studies).In order to investigate the demands for competence I split the concept into ?Soft? competence (socially and emotionally based skills), and ?hard? competence (skills based on knowledge, education and experience).

Generationsskiften i familjejordbruk : genomförande och familjerelationer

Within the next five years about 15 % of the Swedish forest owners that will undergo a succession of ownership. Presently the most common way to acquire a forest estate in Sweden is to acquire it within the family. To decide to let go after a whole life as a forest owner and manager of your own land is for many people a hard decision to make and often requires a long process. The complex process that a succession of ownership often is includes both questions about economy, legal aspects and regulations, taxes and questions of more personal nature, often called Soft issues. These personal aspects or Soft issues are important and can if handled poorly or not at all negatively affect relationships in the family for a very long time.

Hur tillgänglig är staden? : fallstudie av Kungsgatan och Föreningsgatan i Malmö

How accessible is the city? Is there more factors than merely the strictly physical that affect how accessible the city is perceived? These questions are the starting point of this study. The greatest emphasis, in this study, is placed on the perceived parameters that affect us humans when we move in our cities. Experiences and internal images can change our behaviour and prevent free movement in the city. The result from this study shows that a city can not be seen as fully accessible unless both the physical and the perceived accessibility are fulfilled.
