Introduktion av förstakalvare i AMS : en enkätstudie

Habituation to an automatic milking system (AMS) for cows in their first lactation differs from habituation to other milking systems. In AMS the cows are supposed to visit the milking station (MS) voluntarily. The milking takes place individually during the whole day, except when the milking system is cleaned. Milking is carried out without any human survey. The aim of the study was to describe the cow?s introduction in AMS in their first lactation.

De nya riksdagspartierna och den politiska dagordningen

Engblom, Gustav (2009) De nya riksdagspartierna och den politiska dagordningen ?The new parilament parties and the political agenda.?1988 and 1991 the swedish parties Miljöpartiet, Ny demokrati and Kristdemokratiska samlingspartiet made it over the 4 percent threshold and successfully entered the Swedish parliament. Sweden was once described as one of the most stable political systems in the world, but the parliament elections of 1988 and 1991 showed that Sweden was no exception from the growing instability in west democratic political systems.The stability and instability that followed in the west democratic political systems is believed to be explained by the political parties? efforts to adjust to changes in their political environment. This has lead them to cartelize and the cartel party is believed to prefer stability over triumph for various reasons.The established political parties are believed to be able to manipulate the political agenda in such a way that political topics that would have caused great turbulence in the political system, if debated, are kept away from the political agenda.

Automatisering av underhåll av produkter med inbyggda trådlösa sensorsystem : Fallstudie om tvättmaskin

I detta examensarbete undersöks möjligheten att automatisera underhåll med ett trådlöst inbyggt sensorsystem i en fallstudie om tvättmaskiner. Idén är att produkten ständigt kontrolleras via ett trådlös inbyggd sensor-system, där den kopplas upp och övervakas via ett moln. Det presenteras två molntjänster varav ett av dem används. En trådlös sensordesign an-vänds för att visa hur arbetet läggs upp, följt av hierarkiska modeller som beskriver designen i hårdvaru-och mjukvarunivå. Fem olika input-/outpu-tanalyser presenteras, där viktiga parametrar undersöks utifrån flera olika perspektiv och sensorer som kan mäta dessa parametrar.Som det framgår i resultatet, används den mest effektiva input-/outpu-tanalysen praktiskt på tvättmaskinen samt att prototypen anpassas efter den valda input-/outputanalysen.

Strömkontroll till aktiva magnetlager med noggrann och störningsreducerad strömmätning

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

Digital guidning på campus Alnarp : tekniska lösningar för riktad information till olika målgrupper

Today digital guides are most frequently used by the museum and tourism industries. They are also used for education purposes. They make it possible to distribute information and have it easily accessible. In addition to written information they add sound, pictures and videos which lift the whole impression of the visited place to a higher level. A variety of systems currently in use today have been evaluated.

Energianvändning i serverhallar: energiflöden och kylning

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

Sensorfinger

Målet med detta examensarbete är att ersätta den tidigare lösningen av sensorfingret med andra komponenter, eller hitta en annan sensor med motsvarande funktion.Arbetet har begränsats av att ESAB vill ha ett mekaniskt finger för användarvänlighetens skull. Efter en förundersökning av olika typer av sensorer har vi valt att använda oss av trådtöjningsgivare som sensorer till det mekaniska sensorfingret. I och med detta val behövde vi även komma med ett teoretiskt förslag på en mekanisk upphängning av sensorfingret.Vi har byggt upp två separata Wheatstonebryggor med varsin instrumentförstärkare (INA125). Utsignalen från bryggorna är relativt liten och behövde förstärkas cirka 2000 gånger.Nollbalansering av bryggorna har skett manuellt med potentiometrar men vi har även gett ett förslag på en lösning där nollbalansering kan ske med ett enkelt knapptryck. Knappen är placerad på upphängningen på ett sådant sätt att man inte kan trycka oavsiktligt på knappen.Resultatet av arbetet är en uppkoppling på en experimentplatta samt förslag på hur upphängningen och sensorfingret designmässigt kan se ut.För vidare arbetsgång behövs en prototyp för att testa livslängden och ta reda på vilken känslighet som är mest optimal..

Vikten av säkra nätverk

The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.

Undersökning av avfallshanteringssystem : För ett nyexploaterat område i Ekhagen, Jönköping

Outside of many Swedish households today, you will find a typical green wastecontainer. This container has not changed since its introduction, despitecomplaints about foul-smelling and its impractical system. Even if the system usedtoday, still is the most optimal choice, there is a lot of newly developedalternatives out there.Its purpose is to get a broader perspective on how a waste management systemcan be developed into a working, land efficiently and aesthetically pleasing systemof humans and the environment in a small residential area.The authors treat the residential area of Jära, Ekhagen, in Jönköping, which ismanaged by JM AB as a problem area in regards to waste management.The issues raised by the authors are the different waste management systems usedin the corresponding areas of the world, how to apply technical andenvironmental as well as the waste management facilities from financial aspects.In the process, the methods used were literature reviews, case studies and aninterview. The case study was done through a modeling of waste managementsystems in the area Jära and an interview was conducted with the company Envacworking with vacuum systems. Studies have been made by different systems n theareas around the world.The results show that using directives and guidance will reduce the environmentalimpact done without replacing the traditional system.

Optimering av reducerad bearbetning : högre skörd till lägre kostnad

Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.

Förslitning av fräsverktyg

Sweden is dependent on secure sea transport. Shorter disruption of imports of fuel and crude oil can be managed with an emergency stock, but a prolonged halt in imports creates problems. For industry, the vulnerability is greater. Fragmented production chains in combination with expenditure reductions in inventory causes a dependency on proper transport of intermediate goods in the manufacturing industry. A lengthy disruption thus involves disruption of production for both domestic consumption and for export goods containing imported parts.In order to secure shipping routes with a limited number of vessels, Mine Counter Measures (MCM) capacity is required, and according to the Armed Forces, developed with new sensors and autonomous vehicles.
