The purpose of this report was to compare two different options for expanding of an existing pig farm. For the time being there are low prices within the agricultural market of pig production, and it is interesting to see if it is worth expanding or not. The two different options this report is based on are: expanding from a herd with 50 sows in breeding gilt production to a herd with 100 sows in breeding gilt production (option 1), or expanding to a herd with 140 sows in breeding gilt production (option 2). The number of pregnant gilts produced per year will stay the same for both alternatives; about 300 pregnant gilts per year. The rest of the breeding gilts will be sold at a weight of 25 kg. The pigs that are not sold as breeding gilts (e.g. castrates, and female pigs that are too small or that have disorders) will be kept on the farm as growing-finishing pigs until 120 kg of live weight, and then sold to the slaughter house. By using the existing buildings, even after the expanding, the investment costs, and thereby costs for housing, were kept as low as possible.

According to the national legislation concerning discrimination within labour law, it is prohibited to discriminate on the grounds of sex, ethnic belonging, religion or other religious belief, functional disability, sexual nature and part-time work or time-limited employment. The EC-law goes further and also prohibits discrimination on the ground of age. According to an EC-directive the member states must incorporate a national provision against age discrimination by the 2nd of December 2006 and the Swedish legislator is now in the progress to implement this into Swedish law.Even though national legislation does not contain any provision on the area, the EC-law directive has a certain influence at national law. Measures that are in breach of the purpose of the directive can for example not be taken. When the time for implementation has expired, the directive has direct effect and can be referred to within the member states.

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

I detta examensarbete har ett problem som varit en del av ett pågående projekt på ElektaInstrument AB undersökts och en lösning har föreslagits.Problemet har varit att utveckla och modellera en servoenhet som med hög precision kanpositionera ett instrument i fem dimensioner (tre translaterande och två roterande) och som kanhålla instrumentet på sin position med hög styvhet.Problemet löstes genom att först specificera kraven på servoenheten, sedan undersöktes olikabefintliga koncept för att uppnå kraven. Det bästa konceptet, en Stewart-Gough plattform, valdesoch studerades och analyserades sedan i detalj.Analysen gjordes i två steg, det första steget var att göra beräkningar av krafter och benlängdersom en funktion av positionen för en Stewart-Gough plattform. Det andra steget var att realiseraberäkningarna och implementera dessa i kod och hårdvara för att styra fysiska motorer och fådem att bete sig som önskat enligt beräkningarna.Resultatet av första delen av analysen är ett MATLAB program som kan beräknainverskinematiken och benkrafterna för en godtycklig Stewart-Gough plattform som belastasmed en godtycklig kraftvektor och en godtycklig momentvektor. Programmet kan även itereraberäkningarna för olika lägen för Stewart-Gough plattformen och för olika belastningar ochskriva ut extremvärdena som beräknats.Den andra delen av analysen resulterade i ett LabView program för simultan styrning av sexmotorer och hårdvara för att driva sex motorer. Styrningen har testats på befintliga motorer medlyckat resultat.Resultaten av examensarbetet visar att Stewart-Gough plattformen kan uppfylla kraven som ärställda på servoenheten.

Syftet med denna undersökning är att undersöka hur lärare idag designar (formar) elevers sätt att öva. Det har visat sig i tidigare studier att det finns stora brister hos många nybörjarinstrumentalister om hur man gör och vad övning egentligen innebär? Vissa elever övar utan att veta på vilket sätt de kan få användning av övningen och kanske med fokus på att göra läraren nöjd istället för att utveckla sin förmåga till att musicera på sitt instrument. Andra elever kanske vet vad dom vill uppnå med en övning men har en bristande övningsteknik. Denna uppsats går inte in i detalj på strategier kring övningsteknik, men tar däremot upp frågor kring lärarens sätt att arbeta med övning för eleven i förberedelse inför lektion, kommunikation under lektion och i uppföljning av lektionen.I mitt arbete har jag valt en kvalitativ studie där jag intervjuat sex stycken instrumentallärare, som undervisar i olika instrument och arbetar på olika kulturskolor.

AbstractTitle: Manipulation or relation ? the language as an instrument for influence (relation eller manipulation ? om språket som medel för påverkan)Number of pages: 42Author: Matilde JohanssonTutor: Peder Hård af SegerstadCourse: Media and Communication Studies CPeriod: Autumn term 2007University: Division of Media and communication, Department of information science, Uppsala universityPurpose/Aim: The aim of this essay is to gain a deeper understanding of how communication consultants work with communication. The purpose is to sort out whether or not the consultants have the same view in their strategic work with influence as they have when they build relations to customers. In the end the essay will answer if the perspective is the same between their strategic work, their relations and the research definition of how to obtain a genuine dialogue and a good relationship.Material/Method: This is a qualitative research. I have interviewed five communication consultants from three different corporations.

Aeroseum is an aviation museum located in an old military underground hangar. The ventilation system in the hangar is designed for the military purpose of the hangar. This design includes a solution with air flowing through the space between the construction of the hangar and the rock surface. The solution is intended to avoid a buildup of inflammable gases. This design leads too high humidity levels in the hangar.

Requirements management is an important part of the software development process. The success of a project may depend on how this is handled. Even though several research studies indicates that more attention should be paid on non-functional requirements, the primary focus in practical projects still regards identifying functional requirements. Especially the prioritization of the non-functional requirements has been proven to be of great importance for the success of a project.This report investigates basics in agile requirements management involving opinions from experts from a software development company. This is done with help of existing literature and interviews with key actors involved in prioritization at the company.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

The aim of this report is to increase the knowledge and understanding of the problems within the production at AQ Enclosure systems, and thereby achieve a more stable flow throughout the whole process, a better working environment and better competition advantages. The internal flow along with the external cooperation is very important for the company, because it views flexibility and short leadtime as it is the most important competitive means. The part of AQ production that?s been investigated is the manufacturing of ATM-machines, where the costumer is Banqit. This company is a rater small company with about 4 % of the world market of ATM-machines.In order to achieve the aim of the report extensive interviews have been carried out with employees at AQ.

Life Cycle Cost, often abbreviated as LCC, is a common tool for comparing the total cost of different alternatives, such as heating and cooling methods. Common heating and cooling methods in Sweden are geothermal energy, district heating and district cooling. This report aims to evaluate how different heating and cooling methods differ from each other while being applied on three different types of buildings, using selected LCC-models. Information about the selected LCC-models wasretrieved from each separate model and its website. Reports and agencies were used as sources for information about the heating and cooling methods.

Syfte: Syftet för denna studie var att se om det var någon skillnad i den överrefraktion man får fram hos patienten när överrefraktionen genomförs i provbåge, foropter och autorefraktor. Undersökningen gick även ut på att se om det blev någon skillnad om överrefraktionen genomfördes monokulärt med ocklusion eller binokulärt med dimlins.Metod: I studien deltog 30 personer i åldrarna 19 till 42 år. Det var sammanlagt 13 lågmyoper, 3 högmyoper, 5 hyperoper och 9 emmetroper som deltog i undersökningarna. Av dessa var 8 personer inte linsbärare och blev tillpassade med linser utifrån k-värden och HVID för att få en så bra sits som möjligt på linserna. De andra deltagarna blev tillsagda att komma till undersökningen med linser ordinerade till dem av en leg.

This report examines the possibility of optimizing troubleshooting log files generated when constructing new Volvo trucks. Errors occur when CAD models are stored and managed by the versioning system PDMLink. By developing a new diagnostic tool, Log Search, the troubleshooting process is automated and thereby streamlines the current manual search..

Global warming is a huge issue that humans have contributed to through over-exploitation of natural resources and extensive usage of fossil fuels. Now more than ever, we need to embrace a recycle thinking and reuse our waste, for example through producing biogas from our food waste. The purpose of this report was therefore to identify the energy usage and emissions resulting from the biogas chain which spans from Solna Stad to Uppsala Vatten. Furthermore, potential efficiency improvements were to be identified and proposed. This report focused mainly on the first part of the biogas chain that includes the collection of the food waste and the reloading process.

This is a final year project considering constructional techniques for joining cavity walls. The project is related to an ongoing scientific programme about the restoration of The City wall of Visby located on Gotland. The programme was set by Riksantikvarieämbetet as a reaction to a collapse of the outer masonry wall shell which took place in February 2012.The City wall of Visby is a medieval fortification built out of limestone during the 13th century. The wall is constructed as a cavity wall with two separate masonry shells connected to each other through an intermediate core. During the 14th century the wall was heightened which lead to a higher stress, especially in the outer wall face.
