DESIGN AV ALUTON 38? FRAKTBÅT FÖR KUSTNÄRA TRANSPORTER

This master thesis is about designing and dimensioning a boat for transport of caravan, car, trailer or ATV. Buoyancy and stability are important properties as the pontoonboat should also be able to serve as a workboat. Many of the vessels on the market today that is being used for similar purpose are stable enough, but their hull is often similar with barges and thus too slow. This work has been to construct a boat that has good stability but also has a hull that enables it to move faster, is more maneuverable and having a more attracting design than today?s barges.

Vitpunktsförskjutningens påverkan på ICC-profiler vid användande av optiska vitmedel

The connection between fluorescence and color management still is a relatively unexplored area. Thefollowing composition analyses the theory that when printing on fluorescent ink jet paper using ICCprofilesa more yellow print will appear. In theory the ICC-profile compensate for blue light that fluorescefrom the paper with the complementary color, yellow. The human eye apprehands this fluorescentlight as white.When categorizing a number of ink jet qualities some tests to indicate change of color in the final printwere made. Five qualities were chosen for further analyses, each with different white point.

Clostridium difficile toxins in meat-producing guinea pigs in the highlands of Peru

The guinea pig is an important meat-producing animal in Peru as well as in several other South American countries. They are held in different kinds of systems, from the small backyard breeders with few animals to the large commercial farms with thousands of guinea pigs. One of the major issues at the farms is animals dying of unknown causes. Salmonellosis is often considered as a major cause, but samples for confirmation are rarely taken. It has been known for a long time that Clostridium difficile (C.

De nationella provens påverkan på det pedagogiska uppdraget : - en studie om lärares inställning till införandet av nationella prov i åk 3

Vid regeringsskiftet 2006 kom det att bli förändringar inom skolpolitiken och det blev startskottet för denna undersökning. Skolverket fick i uppdrag att utforma nya kunskapsmål att uppnå i ämnena matematik, svenska samt svenska som andra språk. Detta föregick införandet av nationella prov i årskurs tre. Syftet med undersökningen är att ta reda på grundskolelärares inställning till hur proven kan komma att påverka det pedagogiska uppdraget.Insamlandet av material har skett genom en enkät bestående av fasta svarsalternativ och det har getts möjligheten för skriftliga kommentarer.Resultatet visar att lärare anser att de nya problemformuleringarna är en vinst för elevernas kunskapsutveckling och inte proven i sig. De nationella proven ses som redskap att synliggöra elevernas kunskaper och till viss del kan de komma att ligga till grund för bedömningar av elevernas kunskapsutveckling..

Läsinlärning i finlandssvenska skolor : En undersökning av lärares syn på läsinlärning i årskurs 1-2 vid tre finlandssvenska skolor.

Finnish student have for several years proved to be successful in reading in international studies. This interview based study aims to describe how teachers in Finnish schools for Swedish speaking children are relating to reading and reading education during the first two years of schooling. The result shows that reading, reading training and reading comprehension are natural elements in all teaching during the first two years in school and that teaching is based on students? ability and interest. The teachers claim that they provide the students with varying opportunities to practice different kinds of reading.

Mortalitet och skottskjutningsförmåga hos ek (Quercus robur) efter brand :

In this study I analysed how burning affects sprouting ability and survival of oak (Quercus robur) during the first season after a burn in southern Sweden. The study consisted of two separate field tests; in the first, two 300 m2- plots in western oak dominated forest were burned to analyze the fire behavior and the immediate mortality of oak and beech seedlings defined as individuals (> 20cm of height). At the end of the season almost 50% of the oak seedlings had resprouted while the beech seedlings had 100% mortality. An attempt to investigate the effect of the burn of artificially sown acorns was totally ruined by wild boar grouting before any conclusive results could be seen. In the second test the resprouting ability of oaks of varying diameters (average BHD 7-9 cm, range 2-42 cm) was examined one season after a prescribed burn in southeastern Sweden.

Läsförståelsekompetens. : En kvalitativ studie av några pojkars läsförståelse

AbstractThis essay concerns a qualitative case study seeking to understand six boys? reading habits and to investigate why it is that some boys who do not like reading nevertheless display good reading comprehension according to the results achieved for that skill in national tests. The study shows that the boys? perception of reading has a lot to do with the contact they have with books when they are small. Whether or not there are adult role models in the home and whether the early encounter with texts in school is a positive or negative experience is significant for the boys? later attitude to reading.

Tankefel, vad är oddsen för det - En studie om konjunktionsfel bland konsumenter inom vadhållning på sportspel

Several studies have shown that people misjudge and fail to correctly combine probabilities. An explanation for these tendencies is the conjunction fallacy. Basically, the conjunction fallacy refers to violations of the conjunction rule, which states that the probability of a combination of two independent events (A & B) cannot exceed the probability of neither event (A or B). In connection with the growth of the Swedish gambling market and the fact that betting is an everyday-event containing well-defined probabilities, it is considered to be both up-to-date and relevant to study whether the conjunction fallacy also occurs in betting. Previous studies have shown that people fall victims of the conjunction error, however, only in controlled laboratory settings.

Hur föräldrar uppfattar läxan och de problem som kan uppstå med den : En kvalitativ studie om föräldrainflytande

My aim is to find out about teachers? perceptions of methods concerning learning and assessment of oral proficiencies. My questions are: What perceptions are there among teachers concerning assessment of oral proficiencies? How do teachers describe their ways of promoting and assessing oral proficiency? In order to answer my questions and obtain data I have accomplished two focus groups interviews with seven language teachers. The result shows that teachers are concerned with several factors regarding assessment of oral proficiency.

Förbättrad resistansmätning för grova aluminiumledare

The goal with this master thesis has been to evaluate and to examine the stationary resistance bridge. The resistance bridge uses a 4-point measuring to determinate the resistance, which is used in the manufacturing of the conductor. It is then used when the resistance is to be decided for coarser aluminium conductors. A conductor has to fulfil certain demands to be able to move forward in the process. One of these demands is the resistance in ohm/km, which has demands that the measure values of the resistance bridge are as true and precise as possible.

How Does Board Structure Influence CEO Compensation? - Evidence from Sweden

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are included and significance tests are conducted. The study is based on information regarding CEO compensation, and possible factors affecting the compensation, from 267 companies listed on the Stockholm Stock Exchange A- and O-list in the year 2004. We find that the board structure has no significant effect on the CEO compensation.

Robotstyrning med metoden Sliding Mode Control

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.

?Verksamhetsmålen, jag vet att de finns!? - en studie av en glesbygdskommuns verksamhetsmål utifrån personalens perceptioner inom Socialpsykiatrin

Blood-borne infectious diseases such as Human Immunodeficiency Virus (HIV)and Hepatitis C Virus (HCV) spread when the addicts share needles and injecting equipmentwithin contact networks. A quantitative cross-sectional study was conducted in Winnipeg,Canada in December 2003 - September 2004. Through a special questionnaire, respondentswere asked to answer questions about themselves and about their contacts, about relationshipsand how they shared syringes and other injection supplies. Blood tests were used to identifywhether they carried any blood-borne infectious diseases. We selected some variables from theoriginal data set.

?Kryddan i maten? : Redesign av en kokbok

The purpose of this project has been to redesign an already existing cook-book. The title of the book (directly translated), ?Season in food ? the year around with herbs and spices?, contains what the headline imposes: spices, herbs and food. But when the author tries to entwine these parts and communicate it to the reader it is not working all to well due to a poor and inconsistent graphic design.I have followed the theories and values of information design when I redesigned the book layout with the intent to simplify the communication between author and reader. In the progress to make a complete dummie of the book I did multiple literature studies, book analysis, tests and a vast number of drafts.In this report I will describe the whole process from start to finish.
