Kan ät- och liggbås påverka kornas välbefinnande?
The purpose of this literature review was from dairy cows? behaviour and welfare point ofview describe how feed bunk and cubicles in a loose house system should be designed. Todaydairy cows in Sweden and in the world have high demands because of a high milk production,stress and higher risk of being afflicted with diseases. Through selection in breeding the bestquality can be performed, but high demands of the environment for the dairy cow is above allalso important for a good welfare and for a good milk production. Feed bunks and cubiclesare just some parts to be designed in the best way for a good animal welfare.
Skattningar i gallringsskog med hjälp av flygburen laserskanning : beräkningar med massaslutenhet
This master?s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The study area was in the municipality of Älvsbyn (Latitude 65° 40´ N, Longitude 21° 00´ E), in northern Sweden.The Swedish authority Lantmäteriet is currently laser scanning most parts of Sweden, providing new opportunities and applications. The primary aim of the national laser scanning is to create a new elevation model, useful in consequence analysis of climate changes.
Analys av data från flyglaserscanning :
In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality.
StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data.
The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.
Dikesavståndets inverkan på såtid och skörd
All arable land in Sweden need a proper drainage for an effectively agriculture to take place. Of all arable land in Sweden, about 50% is naturally drained and 50% need artificial drainge. More than half of the tile drained area is in need of new drainage or renewed drainage. A good drainage improves farming and crop growth and increases the opportunity to achieve a high and safe harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage.
In this paper, two trials with three drainage distances, performed at Lanna experimental station, were analyzed using a mixed linear model.
Undersökning av elkvalitet i distributionsnät med omfattande vindkraftselproduktion
The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
Omkonstruktion av hjulvändare
Duroc Rail AB utför underhåll av järnvägshjul till olika järnvägsoperatörer. Duroc har för tillfället problem i verkstaden med en av de två hjulvändarna, dessa hjulvändare har som uppgift att ta emot, växla och vrida hjulpar till ett korsande spår. Hjulvändaren knuffar sedan vidare hjulparet till nästkommande station. Genom att använda sig av en hjulvändare kan ett hjulpar växlas till ett korsande spår och på så vis möjliggöra att ett hjulpar som endast behöver svarvas om kan slippa passera nästkommande stationer. Den hjulvändare som Duroc har problem med har trasiga bälgcylindrar och då det inte finns reservdelar till denne har Duroc valt att man vill omkonstruera eller hitta en ny lösning på hur hjulparen ska vändas.

Automatisering av härdugn
Examensarbetet har utförts på Metso Refiner Segments AB i Hagfors, Värmland. Gjuteriet arbetar mot pappersindustrin och produkten de tillverkar kallas för malsegment. Malsegmenten sitter monterad på två stora skivor i en raffinör, vilket används för att framställa mekanisk pappersmassa. För att minska personalkostnaderna och för att få bort ett monotont moment för operatörerna vill Metso automatisera den station där malsegmenten härdas. Värmebehandlingen sköts idag av två operatörer och är tänkt att efter en automatisering kunna skötas av en operatör.

PPP - Ethernet gateway RS232 - RJ45 network adapter for an Echelon ?Data Concentrator?
För närvarande läses elmätare av en gång per år, detta leder till att kunders elräkning baseras på ett schablonbaserat belopp. Enligt riksdagens proposition 2002/03:85 skall dock alla elkunder, senast fr.o.m. 1 juli 2009, faktureras efter faktisk elförbrukning varje månad. Detta har lett till en stor marknad för fjärravlästa elmätare som nu är ett måste för att kunna utföra den tätare avläsning som krävs. E.ON ES Sverige AB som är beställare av detta examensarbetet har specialiserat sig på att installera, underhålla och läsa av fjärravlästa elmätare åt nätägare.

Helandet av Stockholms sår : En analys av projektet Västra City
Over the years, what people have considered as the center of Stockholm City has gone from the medieval Stortorget in Old Town to the contemporary Sergels Torg. But more recently it has become unclear how the area really works. It is difficult to say where the actual central part of Stockholm lies, because while the Central Station is where the majority of people arrive into town, it is not necessarily close to Sergelstorg (considered the center of town) or other attractive commercial areas. There's also another issue with where the center of Stockholm is located. The railways and roads running along Klarabergs Viaduct acts as a divide between the areas of Kungsholmen and Norrmalm; these rails, roads and water separate the two areas from each other. In response to this problem of area division, a plan is being made to construct a new district near the center to mend the gap between the districts. The idea is that the center of Stockholm city will become more lively and attractive. The plan includes building new housing, commercial areas and a larger terrace called Mälarterrassen. In addition, improved mobility within the area is being planned by having better public transportation lines like City banan and tram named Spårväg City construction, as well as more pedestrian areas shall make the area become a district to thrive in.How the area will actually operate in the future is still unclear and many questions still exist about how the area will be able to compete and, above all, integrate with the other districts. The parts considered to be most important for the area is the scale of residential property and an attractive area that keeps people in the area and to encourages them to pass through the area. Perhaps the best solution would be to have something special planned in this area that can attract people in the community ? a city park, for example?.

Sweden will, in accordance with the EU-directive 2003/54/EC, move from post-regulating the electricity power grid-tariffs by using a fictitious grid, to a regulation in advance which uses the actual power grid as a starting point. For this purpose a component breakdown of the grid needs to be made to determine the value of the network and by that the tariff price that is reasonable for the network business in question to charge.The primary breakdown criteria is the voltage-level and type of region. Voltage-level is crucial for the cost and complexity of a grid-part, because the higher the voltagelevel is, there are more and stricter laws and rules to follow. This work is limited to the distributionpart of the grid, in other words voltage levels from 20 kV and below.The type of region is crucial to the type of components you can and want to use. In city environments both overhead-wires and independent substations are undesirable for both practical, safety and aesthetic reasons.
Alternativa stråbränslen i växtföljden :
The purpose of this report is to find out which crops, that are good for strawfuel, and can be grown i the area around the city of Lund. The background of this report it that Lunds energy is planning to bild a biofuelheated thermal power station in Örtofta outside of Lund.
I have in the report limited me to the crops hemp, whole crop (triticale), reed canary
grass, elephant grass and jerusalem artichoke. I have through a documentary research
checked the crops, cultivabillity in the south of Sweden, and how they should fit, in the
Scanian crop sequence.
Hemp is an annual crop which probably could manage in the Scanian crop sequence.
Whole crop often triticale because of it´s high yield and low rate of shed seed. Could
also fit into the crop sequence of crop in Scanian. Triticale is annual, and could be
grown at the same kind of fields as used to wheat, whith is why it would be possible to
grow it in Scania.
Reed canary grass is a reedlike grass that is easy grown at most soils.
Krylbosmällen
Syftet med denna uppsats var att utifrån Hadenius och Weibulls synsätt se hur en händelse blir en nyhet och ur ett historiskt perspektiv studera hur Krylbosmällen blev en nyhet i tidningarna. Syftet var även att se vilken teori tidningarna hade om orsaken till Krylbosmällen. För att besvara syftet användes en kvalitativ och en kvantitativ metod, där jag undersökte fem olika tidningar och litteratur. När andra världskriget startade förhöll sig Sverige neutrala mellan de västallierade och Tyskland och deras allierade. Efter påtryckningar från Tyskland ingick Sverige ett transiteringsavtal med dem.
