This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

The purpose of this thesis is to examine whether Swedish, Internet-based travel agencies, acting on a consumer market are working towards creating added value for their customers. If that is the case, how and why do they use such a mode of operation.The theoretical framework was based on Grönroos´ ?Augmented service offering?, which treats added value as an addition to the core service. The services offered on five of the larger companies´ websites on the market were examined and 3 representatives of the five companies were interviewed.The study shows that 2 of the examined companies did not produce any added value, while 3 of the companies did produce added value for the customer. The added value was generated through packaging of core-, facilitating- and supporting services for the purpose of differentiating the company towards competitors and generating service fees..

Pyometra är en vanlig sjukdom hos äldre, okastrerade tikar. Oftast uppträder sjukdomen i efterlöpet då tiken står under progesteronpåverkan vilket gör livmodern mer mottaglig för bakteriella infektioner. Enligt studier är Escherichia coli den bakterie som vanligen isoleras från livmodern. Bakterierna härstammar troligtvis från tikens normalflora eller från urinvägarna. Kliniska symptom på livmoderinflammation kan vara sänkt allmäntillstånd, variga flytningar (om cervix är öppen), polyuri, polydipsi, feber, diarré och kräkningar.

Induction motors, often referred to as the workhorse of the industry, play an important role in production today. Therefore, it's important to diagnose any faulty induction motor prior to failure to avoid costly and time consuming production stops.This thesis compares methods for diagnosing induction motors in operation, MCSA, Park's vector approach and the standard method used by Swedish industries today. By simulating broken rotor bars and short-circuit in one of the windings, each method is tested and the results are compared using matlab.The results need further verification due to uncertainties of the condition of the test motor, even though the experiment gives a hint of the different advantages of each method. A combination of the methods should be able to tell if the motor needs further examination..

The object of this essay has been to investigate the interlibrary loan service at the universitylibraries of Borås and Kalmar. For this purpose a quantitative and a qualitative methodhave been used.The main body of information consists of statistic data concerning the incoming interlendingorders for a three-month-period. In order to examine the circumstances under which theinterlending activity exists several interviews were made.The study showed that there are several important factors which together make up the complexitythat governs the interlending activity. What type of demand there is depends on theeducational level, whether the different study programmes have a broad or limited subjectorientation or not, and if the demand is of a constant or an inconstant nature. Well-establishedroutines at the information-desk and co-operation with the departments of the different studyprogrammes are important factors in keeping the knowledge of what books and serials areneeded up to date..

This thesis has been conducted at Saab Bofors Dynamics AB. The purpose was to investigate if a non-linear missile model could be stabilized when the optimal control signal is computed considering constraints on the control input. This is particularly interesting because the missile is controlled with rudders that have physical bounds. This strategy is called Model Predictive Control. Simulations are conducted to compare this strategy with others; firstly simulations with step responses and secondly simulations when the missile is supposed to hit a moving target.

In this thesis a rural network in Norrbotten, Sweden, has been to designed and planned with the purpose of improving distribution reliability by exchanging existing overhead lines with underground cables. General network design considerations are discussed as well as the ones for the specific low voltage grid. During the design phase the maximum power of domestic consumers has been estimated using Velander?s method. Currents, voltage drop and impedance of the network have been calculated and fuse operation and selectivity has been considered.

The purpose of this study was to illustrate the effects of music in pre-, peri-, and postoperative care. This study is a systematic literature study based on 22 scientific articles with quantitative methods. Music is an alternative treatment used in nursing care. Nurses could as a complement to routine pre-, peri-, and postoperative nursing have music interventions in mind, because an operation involves anxiety, fear and pain for many patients. The result of the study shows that music can reduce patients? anxiety, pain and improving their wellbeing and recovery.

Syftet med vår rapport är att försöka ge en djupare inblick i ett av polisens mindre kända verksamhetsområden. Vi har valt att arbeta med de regionala insatsgrupperna både för att vi själva vill få ökade kunskaper om deras verksamhet samt för att undersöka hur denna polisiära resurs är organiserad i polismyndigheten. Rapporten försöker att analysera hur de regionala insatsgrupperna skiljer sig åt beträffande arbetsformer, utbildning och organisation i Örebros respektive Västerbottens polismyndighet. De fakta och uppgifter som rapporten bygger på har inhämtats från litteratur och genom intervjuer. Det vi har kommit fram till är att de regionala insatsgrupperna skiljer sig signifikant från varandra och en likriktning av verksamheten genom nationellt fastställda direktiv skulle kunna kompetenssäkra insatsgruppernas verksamhet..

The report begins with a general inventory of possible technical faults in a hydropower plant and of possible fault indicating measurements. Then an investigation is made concerning a few different faults. Based on this investigation a choice on seal box condition and water leakage is made as problem for a more thorough examination, in which it is concluded that the turbine water leakage is larger when the turbine is put into operation. The examination ultimately results in a computer alarm for faults related to the seal box. Finally a few things are mentioned about flow measurement and pressure measurement in relation to the project as a whole..

The implementation of integration policy has in recent times been a major problem for the municipal administrations in Swedish municipalities. The concept of integration is considered to be very diffuse, difficult to apply and implement the following decisions. To understand the concept of integration is the first step, followed by understanding its complexity in an organization.In this study, I focus on studying the implementation of integration policies for integration work with Kalmar Municipality as a case study. I am using Lundquist's implementation theory about understanding, able and willing. The survey consists primarily of interviews but also a certain document to get a perspective on how integration policy has gone into integration work with the hypothesis that it is the understanding that weaknesses of the officials in the implementation of integration policies.

Övervikt och fetma är ett snabbt växande folkhälsoproblem i Sverige, liksom i övriga världen, som ger upphov till bland annat hjärt-kärlsjukdomar och andra negativa fysiska och mentala tillstånd. Enligt den senaste forskningen har magsäcksoperation fastslagits som den mest effektiva metoden för viktminskning vid svår fetma. Syftet med denna studie, som bygger på nio vetenskapliga artiklar, är att belysa på vilket sätt livskvaliteten påverkas hos vuxna individer som genomgått en sådan operation. Resultatet visar att livskvaliteten förbättras, dock inte för alla. Tidigare depression eller ätstörningsbeteende kan i flera fall finnas kvar postoperativt och tenderar då att ge sämre utfall eller inverka negativt på det sammantagna förloppet för individen..

Olika modeller har genom åren tagits fram för att förenkla analys av aktiemarknaden. En relativt ny teknik är så kallade artificiella neuronnät.Dessa modeller har visat sig lovande när det gäller att förutsägaaktiekurser. Projektets syfte är att hitta artificiella neuronnät som ger bra förutsägelser av framtida aktiekurser. Under projektet har ett mjukvarusystemsom genererar och tränar artificiella neuronnät av typen feedforward utvecklats för att kunna testa neuronnät med olika indata, struktur och träningsinställningar. För att komma fram till vilka konfigurationer på neuronnäten som ger bra resultat har näten testats genom simulerad aktiehandel där köp- och säljbeslut grundats på neuronnätens förutsägelser.

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Bakgrund: Den vanligaste tumörsjukdomen hos män är prostatacancer, samtidigt som prostatacancer oftast drabbar äldre män ökar andelen äldre i befolkningen vilket har medfört en ökad incidens. Den vanligaste behandlingen för att bota prostatacancer är operation då prostatakörtel, sädesledare och sädesblåsor opereras bort, radikal prostatektomi. Den mest betydande komplikationen efter detta ingrepp är impotens. Hur impotens efter radikal prostatektomi upplevs är till stor del beroende av sjuksköterskans roll i omvårdnaden. Syfte: Att beskriva vad tidigare studier visat om mäns upplevelser av erektil dysfunktion och dess påverkan på sexualliv och livskvalitet efter genomgången radikal prostatektomi.
