Utveckling av rattstång med övre teleskopfunktion
I denna rapport redogör projektgruppen för resultatet i kursen examensarbete 15hp (C-nivå) utfört på maskiningenjörsprogrammet, inriktning produktutveckling och design, vid Jönköpings Tekniska Högskola.Examensarbetet har utförts i samarbete med Kongsberg Power Product Systems AB i Ljungsarp. Syftet var att utveckla en ny typ av övre teleskopfunktion till Kongsbergs modulsystem för ställbara rattstänger.Utgångspunkten i projektet var att skapa en mer ergonomisk förarmiljö, något som Kongsbergs kunder och marknaden för långsamtgående fordon allt mer efterfrågar. Kraven som ställts på projektet bestod i största del av axiella och radiella krafter som konstruktionen skulle klara av, samt den axiella förlängningen av rattstången.För att strukturera arbetet har en produktutvecklingsmetod från boken The Mechanical Design Process av David G. Ullman använts. Dessa metoder har använts i genomförandefasen för att leda fram till resultatet.Projektet har resulterat i ett koncept som löser Kongsbergs krav på förbättrad förarergonomi..
Värdering av anbud vid kommunala upphandlingar av byggprojekt
The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice.
Utformning av kulvertgaller i lösdriftsstall med hela golv för mjölkkor :
Summary
The size of the Swedish dairy farms increases and also the demands for rational manage-ment of the herd without affecting the animal welfare enhance. One way to handle the manure in the cow shed alleys is to have automatic scrapers. In this system the scraper has to get rid of the manure somewhere. The most common way of doing that today is to let the scraper deliver the manure under some kind of gate or covering over the manure culvert. When the scraper goes under the gate or the covering there is a risk of squeezing animals and farmer.
Konstruktion av serviceutrustning till tunnelborrningsmaskin
The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.
Höga betyg i Textilslöjd : en strävan driven av inre eller yttre motivation
Det finns olika sorters motivation för lärande som kan delas in i inre och yttre motivation. Inre motivation kommer inifrån individen själv och handlar om ett personligt intresse av att hålla på med en aktivitet för aktivitetens egen skull. Yttre motivation kommer utifrån och används för att uppfylla ett mål till exempel att hålla på med en aktivitet för att få beröm eller en belöning. Syftet med undersökningen är att klargöra vilka faktorer som motiverar elever att eftersträva höga betyg (A-B) i textilslöjd eller hindrar elever från att eftersträva höga betyg. Genom att ta reda på vad som motiverar elever är förhoppningen att som lärare kunna hjälpa elever att nå dit de strävar utifrån deras egna önskemål.
Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB
The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.
Bruket av hierateuma i 1Petr dess teologiska och retoriska funktioner
Which theological and rhetorical functions may the naming ????????? of the recipients have had in First Peter? This paper provides a theological and rhetorical analysis of the use of ????????? in First Peter. Theological background is provided through intertextual research on its occurences in the Septuagint (Ex 19:6; 23:22 and 2 Macc 2:17). Analysis of the theological and rhetorical functions of ????????? in First Peter builds on rhetorical methods, and predominantly the work of professor Lauri Thurén.
Fibromyalgi: sjukgymnastiska och närliggande behandlingsmetoder - en litteraturstudie
The cause of fibromyalgia has long been unknown but recent studies has shown that disturbance in the central pain modulation may be the cause. The aim of the study was to examine what kind of physiotherapy and close related treatment methods in the treatment of fibromyalgia there are and to determine their evidence. Articles were obtained by searching through the databases PubMed, Academic Search, AMED/Webspirs, CINAHL/webspirs and PEDro for articles published from 1994 and ten years forward. The study was based on thirty articles that met the criteria for inclusion. To assess the quality of the clinical studies the SBU?s evaluation model was used.

Bangenerering för industrirobot med 6 frihetsgrader
This thesis studies path generation for industrial robots of six degrees of freedom. A path is defined by connection of simple geometrical objects like arcs and straight lines. About each point at which the objects connect, a region, henceforth called a zone, is defined in which deviation from the defined path is permitted. The zone allows the robot to follow the path at a constant speed, but the acceleration needed may vary. Some means of calculating the zone path as to make the acceleration continuous will be presented.
Ideologier i biblioteksbyggnaden ? en fallstudie av Arlövs bibliotek
Library architecture today is a complicated history. Public libraries are no longer merely a place for book storage, but also a virtual library a social meeting place and a place for study. All these diverse tasks and roles emerge in the democratic designing process of a new library and also transform into the architecture. The underlying process is the evaluation and negotiation of the libraries overall tasks and ideas, ideals and values. Multiple ideologies are incorporated in library architecture.

The evaluation of the function of the feeding of sheep herds is suggested to involve the work
effort, the fulfilment of the nutrient needs of the sheep and the feed waste. Mechanisation of
the feeding can be very simple or include high degrees of mechanisation.
Three different farms, representing different levels of mechanisation are presented.
Descriptions and analysis of the feeding systems including mechanisation, work effort and
estimations of the feed waste are made on each farm. The herd with the most advanced feed
mechanisation included a rolling feed band and mix wagon. The other farms were partly or
little mechanised including ad lib feeding from big bales and manual distribution of hay and
concentrates.
The most mechanised farm was able to feed a large herd of sheep at a low work effort and
little feed waste. However, the investment in machinery has to be weighed against the
improved efficiency.
Berusningens funktion på krogen utifrån fyra olika perspektiv
This study elucidates the perceptions of twelve people at an age between 35 and 50 years, on what influence intoxication and drunkenness in the bar environment. The purpose of this study is to create an understanding of the effect the intoxication has on the visitor in the bar environment and this is done through qualitative method interviews. The theoretical frame we use to analyse the empirical data, is divided in to four parts: set and setting, environment and its regions, social behaviour and genus perspective. The theoretical material, together with the empirical data in the form of the results of the interviews, forms the platform for this paper. It is on the basis of these results that our questions finally will be answered.
Musikens inverkan på personer med demenssjukdom : -en litteraturstudie
Då befolkningen blir allt äldre ökar andelen personer som drabbas av demenssjukdom. Att drabbas av demens innebär att kognitiva funktioner försämras. Kommunikationsproblem och problem med daglig livsföring, personlighetsförändringar, brister i empatisk förmåga och svårigheter att kontrollera känslor kännetecknar sjukdomsbilden. Det är av betydelse att finna icke-farmakologiska behandlingar då medicinering inte ger önskat resultat. Syftet med denna litteraturstudie var att få ökad kunskap om hur musik påverkar personer med demenssjukdom.
