Analys och dimensionering av robusta kilspårsförband
This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.

Kortare sintid ? hur påverkar det kons mjölkavkastning, metabolism, hälsa, hull och vikt?
A shorter dry period length has in studies abroad showed some positive effects among high yielding dairy cows. Among other things it has been suggested that the periparturient metabolic stress becomes lower, that the fertility is improved and dry off becomes gentler for the udder, due to a lower milk yield. The milk yield is generally reduced during the first period after calving, especially among primiparous cows. The aim of this master thesis was to investigate how Swedish cows were affected by a shortened dry period, regarding milk yield, metabolism, health, body condition and body weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined.
Utvärdering av AP-fonderna : En studie av AP-fondernas riskjusterade avkastning åren 2003-2009.
The general pension supplement introduced in 1960 which introduced the public pension funds in Sweden. In the late 1990s the Swedish pension system was reformed and established the current structure. Today, funds are one of the most common forms of savings in Sweden and mutual funds are the most common type.The purpose of this study is to analyze the risk-adjusted returns for the AP funds in the period 2003-2009. Study was based on five funds that are most similar and have the same mission. These funds are AP1, AP2, AP3, AP4 and AP7.The method used in this study is mainly based on a survey of the figures and measurable units of statistical methods that have been carried out by a quantitative approach.
Frequency of unsuccessful milkings in automatic milking rotary : effect on milk yield, lactose content and somatic cell count at udder quarter level
Developments in milk production are heading towards fewer but larger herds where the milking process is often fully automated. Automatic milking systems were launched in the 1990?s and in the year 2010 the Automatic Milking Rotary (AMR) was introduced. As a rule there are no supervision personnel present during the milking event in systems with automatic milking. This means that there is a risk that cows can be incompletely milked in one or more udder quarters, for example if the robots fail in attaching the milking cups or if the cow kicks off the milking unit.
Environmental, Social and Governance : Hot eller möjlighet för investerare
This study explores whether environmental, social and governance (ESG) issues affect the monetary value of a company.The samples used in this study have been taken from the Johannesburg Stock Exchange (JSE) in South Africa. Since 2010, JSE have been categorizing companies using the King Code III criteria to establish a Socially Responsible Investment index (SRI index). Companies that fulfill the required number of criteria are classified as 'best performers' using the SRI index. In this study the monetary value of a random sample of 'best performers' has been compared to the monetary value of a random sample of companies without an SRI index evaluation.This study found that companies without a SRI index have a higher unique risk, which means a lower stock price with a higher dividend yield. Companies with an SRI index evaluation have a lower unique risk, which means a higher stock price and lower dividend yield. In conclusion, this study shows that SRI adjusted companies have an enhanced monetary value in comparison to non- SRI adjusted companies..
Konflikter och organisationer : En diskursanalytisk studie av två handböcker i konflikthantering
The situation that one can discern on the Swedish real estate market is that while there are several offices vacant, the need for apartments is high ? the vacancy rate for apartments is non-existent. According to the rebuilding of Skatteskrapan one will realise that the project requires a lot of money, even though it promotes the residential situation. The real estate owner experiences a risk in rebuilding real estates ? whether it will generate good yield or not.
Dynamic alarm visualization using context mapping
För att göra informationen tydligare för en larmoperatör som sitter och övervakar larm som kommer in från ett antal olika nätverkskomponenter så har vi skapat ett system som förser larmen med extra information, kallad Context Type, så att vi kan presentera larmen på ett enklare sätt. Vår informationsberikning, även kallad mappning, är utbyggbar för att möta kravet på framtida utveckling. En webbaserad klient skriven i JavaScript är skapad för att presentera larmen på ett nytt innovativt sätt som är baserad på context typen istället för larmobjektet. Mappningen är skapad med hjälp av Python kod och begränsas av att endast använda textfiler som datakälla och webbapplikationen är endast utvecklad för webbläsaren FireFox samt att visningsintervallet för larmen är begränsat till ett dygn med entimmesintervaller. Mappningen var långsam då vi använde oss av regular expression.
Improvements in milking management through imitation of calf behaviour
Approximately 20% of the milk within the udder of a cow is stored in the cistern and immediately available for milk removal, while activation of the milk ejection reflex is required for removing the remaining milk stored in the alveolar compartment. The aim of this literature review is to describe, evaluate and consider implications of the three different suckling activities that the calf displays during a suckling bout. In terms of milking, these phases are represented by pre-stimulation, stimulation during milking and post-stimulation. Pre-stimulation is commonly performed in order to induce the milk ejection reflex, whereby the hormone oxytocin is released and the alveoli in the secretory tissue are contracted. Time requirements regarding pre-stimulation must be considered in relation to lactation stage and milking interval.
Factors affecting crop insurance decision : a survey among Swedish farmers
Farmers are constantly facing changes, and the exposure to risk requires monitoring these changes. Financial risks, institutional risks, market risks and production risks are the different risk categories that the farmers face. Production risks stems from factors the farmer cannot affect or is beyond his control. The crop?s output is the basis for the primary income of agricultural operations, which is why it is important for farmer to manage their production risk.
A tool to reduce the consequences of production risks is crop insurance.
UTREDNING SAMT UTVECKLING AV ETT PLATTFORMSOBEROENDE GEOGRAFISKT INFORMATIONSSYSTEM
This thesis have been performed at Sweco Position in Jönköping. The work was split into two, where one part included an investigation regarding the possibility of developing a cross-platform GIS (geographic information system) with HTML5 and CSS3. A prototype would also be developed within this part.The second part included development of a cross-platform GIS for a client to Sweco Position. The client operates in the forest sector and had already an existing solution, with many problems. The client required an application with delimited functionality and which was not bound to a specific hardware.As the client users often were located in areas with limited Internet access, one additional requirement was that there would be some offline support.The students handle subjects within development of GIS, for example map projections, map services and mapping libraries.The application came to be developed in HTML5 and ASP.net.
Kultur i förändring : En vidgad syn på kultursektorn och dess roll för samhället
How can you do a right measurement of culture as well as with other social sectors and with what can culture contribute when it comes to a town´s development? We found out that in Linköping the regional federation Ostsam recently (2005) started mapping the region's creative centers in order to look into the spreading of the culture in the county, and then use the uniqueness of the culture as an advantage in society- planning contexts. The reason was that both municipal - and State directions detected that the culture has a broader importance when it comes to building up society and infrastructure than earlier considered. This is called Cultural planning and is the foundation- method that Östsam used when working with their new projekt The creative sector. The outcome of the Östsam study resulted in an exciting study basis to work further on with and to examine through own demarcations and directions.This research manages the matter of the creative sector as an extension to the cultural sector.

Positionering och kartuppbyggnad med avståndsmätande laser
This master thesis includes a description of how a number of sensors are put together in a sensor platform. It also gives a description of how localization and mapping has been performed with data collected from the sensor platform. Localization is a prerequisite for most of the tasks that can be requested from an autonomous mobile robot. In many situations the GPS signal is not available and hence an additional localization system is required. One approach is to apply localization based on landmarks extracted from the robots surrounding.
Bäddodling av matpotatis :
This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes.
Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient.
In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
