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.

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.

The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture. In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.

Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.

Denna rapport beskriver arbetet med att designa och utveckla en plattform för simulering ochutvärdering av olika tradingsystem.Det viktigaste kravet som sattes upp i examenarbetets förstudie var att åstakomma en flexibel ochutbyggbar grunddesign för att man vid senare tillfälle ska kunna uttöka systemet vartefter behov avmer funktionalitet uppstår i en snabbt föränderlig finansiell värld. Vidare skulle Microsofts allrasenaste teknik användas.Resultatet blev systemet Trader som är en modulbaserad applikation med tydliga riktlinjer för hurmoduler ska laddas, skapas, initieras samt hur de kommunicerar med varandra utan överflödigaberoenden. Vägen dit gick via inlärning av diverse designmönster och designprinciper. Omfattandeanvändning av händelser och kommandon för kommunikation mellan olika moduler samtprogrammerandet mot interface istället för konkreta objekt i alla lägen gav få beroenden och enflexibel och utbyggbar grunddesign.Trader kan koppla upp sig mot börsen för att hämta kursdata. Denna data kan sedan användas för attutvärdera hur olika tradingsystem skulle ha presterat i olika tidsintervall.

The aim of the study was to evaluate the social integration amongst newly arrived students in the two different school systems Sweden welcomes them into. The first school system takes in newly arrived students into preparation classes whilst the other integrates the students directly into ordinary classrooms. The examination is based on qualitative observations in the classroom, canteen, and playground, and interviews with teachers and a select few students from each school system.The result of the study showed that newly arrived students in ordinary classes are socially integrated more into the school than the newly arrived students that are welcomed into a preparation class. Newly arrived students are offered a larger chance of being integrated into the school environment if they are introduced directly into an ordinary class. In preparation classes, social integration is narrowed down to between the classmates.

Miljöbron is a non-profit organization; their main purpose is to merge companies and students into different environmental projects. The projects can be an assignment, practical vocational training or degree thesis. Miljöbron is expanding and the demand from students and companies is rapidly growing. Because of the expansion, a large amount of information needs to be stored and managed in a structured database. Also the need of a interface that is structured and easy to use when managing information and Miljöbron?s statistics, for Miljöbron?s staff.

The purpose of this essay is to study uses of history in a complementary teaching material in the subject of history. The material in question is a 170 page book titled Hitler och Stalin- En bok om ondska. In English, ?Hitler and Stalin- A book on evil?. Essential to the study is that it is expressed within the material that it might be used as the basis for a discussion of the threats against an open democratic society.

En grafisk ritare i flygande system måste under dess utveckling verifieras för att bekräfta att den fungerar. Då bilderna som ritas inte behöver vara identiska mot referensbilder genererade av en fungerande ritare så ställer det krav på verifieringsprocessen att kunna acceptera en viss grad av "fel". Att automatisera den processen är i högsta grad intressant för att minska kostnaden. Uppsatsen presenterar en samling lösningar på delproblem som kan uppstå, däribland ett sätt att utvinna eventuell transformation mellan två bilder..

This thesis is carried out at Portsystem 2000 AB who manufactures and markets industrial doors and docking systems. The background to this thesis is that the company?s management considers that their follow-up process of cost accounts is not fully functioning.The aim with this report is to investigate and describe the present procedure of the follow-up process concerning the time of operations and come up with suggestions for improvements. This thesis is performed within the range of the following areas: Information systems, quality, processes and cost calculation. The main method we used were semi structured interviews with a fairly opened framework.

This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.

This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".

An often encountered problem when implementing a mass flow regulator in a rolling mill is the one with measurement of speed. The most widely used solution is to fit a pulse counter to a wheel that is in contact with the strip. Common problems with this design are for instance scratch marks on the strip and problems with the flatness measuring system.  One way of circumventing the aforementioned problems would be a non-contact measuring system. The market of today only offers systems based on the Doppler principle.This report evaluates three different systems for non-contact speed measurement. Important areas in the evaluation have been the ability to operate under normal rolling conditions, integration in existing control system and how well the sensor can be fitted to the rolling mill.

Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.
