Jordbearbetningsstrategier på hösten inför vårsådd på tyngre lerjordar :

It is important for today?s farmers to minimize the costs for crop establishment, because of decreased prices and support from the EU. Farmers, who plow in autumn on heavy clay soil, often do some kind of tillage in autumn to get better soil structure before spring seeding. This is especially important when growing small seed crop, e.g. sugar beet and oil plants.

Arbetsmätningssystem på Scania Vehicle Service Information : En analys av nuläget samt framtagande av rekommendation för framtida utveckling

Scania CV is one of the world's largest truck manufacturer. It is not only the directproduction of vehicles and methods that are important for Scania but also the servicemarket handling spare parts, repairs and workshops. The department Vehicle ServiceInformation construct standard times through work measurement for particularworks in the workshops. The software application STAM is used in the servicemarket to create and store standard times which then are exported to theworkshops' own systems.The purpose of this master thesis is to analyse and evaluate the internal workmeasurement system that includes standard times and the software STAM. Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.

Jesus - världens första rocker?: En jämförande studie mellan kristen och sekulär metal

Kristen metal? Kan man verkligen kalla något kristen metal?Heavy metal är ju en rebellisk reaktion mot en samhällsstruktur av människor som inte känner sig hemma där. Och kristendomen är ju en religiös rörelse som står för ordning, reda, renhet och kärlek.Eller?Syftet med denna studie är har varit att studera likheter och skillnader i låtstruktur, dynamik och klangfärg mellan kristna och sekulära metalband och se om de används på samma sätt i förhållande till texten.Jag har gjort en komparativ analys av låtar av kristna och sekulära metalband och tittat på möjliga likheter och skillnader. Detta innefattar även en konstnärlig del där jag, i relation till det analyserade materialet, skrivit två låtar själv och dokumenterat dessa i klingande form.Som material till denna studie har jag använt mig av vetenskapliga artiklar, låtmaterial samt intervjuat pastor Bob Beeman från Nashville, som är en av pionjärerna bakom kristen metal..

Sociala medier i offentlig sektor : En rättsdogmatisk uppsats om problematiken kring hur yttrandefriheten inskränker lojalitetsplikten inom den offentliga sektorn i samband med sociala medier.

Social media has recently expanded dramatically, as more people are using different media such as blogs, Facebook and Twitter, to express their opinions. This increases the possibilities to spread information and an unclear legal regulation in this area can create adverse consequences. Freedom of expression is a constitutional right, which forms an important cornerstone of a democratic society. Public employees? freedom of communication means that they can submit information to the media, without fear of reprisals from the authorities.

Förhållandet mellan arbetsrätt och straffrätt för statligt anställda : - särskilt vid åtgärder mot främlingsfientlighet inom polisen

What happens when employees within the police-force make mistakes in their line of duty? This essay set out to investigate the relationship between labour law sanctions and the criminal law punishments for wrongful acts for government employees. This relationship is also set in the perspective of how acts or statements of xenophobia are handled within the Swedish police-force. Further, the essay aims to examine the principle of ne bis in idem in relation to labour law sanctions and criminal law punishment for wrongful acts, and if these two should be considered in line with this principle. Regarding the relationship between labour law sanctions and criminal law punishment for government employees, the determination for which system to use in any given situation is not fully stipulated.

Nivådiagnos med sensorfusion : Utveckling av koncept för nivåmätning i lutande tankar 

Today?s system to measure the volume in a tank consists of a vertically placed sensor. When a vehicle is tilted the level of the fluid might change and if the volume is calculated based only on the information from the sensor it could result in a incorrect value.This thesis exams a new method to calculate the volume in tanks by using sensor fusion to crosscheck the i formation from the level sensors when the vehicle is tilted. The information is then used to see if it is possible to identify the grade of tilt by the change of fluid level. If the grade of tilt can be measured then the volume can be calculated in a more accurate way.

PSQS ? Power Supply Quality Simulator

Kitron had wishes to be able to test and measure how disturbance affects their vehicle electronic units before they have been verified by SP Technical Research Institute of Sweden in Borås. This work started with the writing of a demand specification together with Kitron for a product PSQS, Power Supply Quality Simulator, which can generate some test pulses according to a standard for electronic units to Volvos vehicles. A design proposal was developed with the help the demand specification and was verified with the help of simulations. All electric schematics was designed with the guide of the design proposal. The pulses realized in the works of this thesis are those which Kitron experienced that they have a need to test in their own premises and which are possible to generate with the means available.

Utveckling av Mätmetoder för Färdmotstånd

The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.

Arbetsgivarens primära förhandlingsskyldighet samt undantag från densamma enligt 2 § MBL

AbstractThe employer is obliged to initiate negotiations with the union organization to which the employer is bound by a collective agreement. This applies both to decisions which imply a substantial change in workplace operations or employment conditions of the individual employee. In case law this obligation has been very extensive through all cases that have been up in the Swedish Labor court. Due to this fact the employer?s duty to negotiate has been interpreted very broadly.

Virtuell hållfasthetsprovning av en turistbuss

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.

Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.

Tungmetallers påverkan på bottenfaunans artsammansättning i sjön Tisken

The purpose of this study was to investigate how elevated levels of heavy metals affect the faunal species composition, abundance and species-diversity. The bentic macroinvertebrate fauna in the highly polluted lake Tisken was compared with the bentic macroinvertebrate fauna in the unpolluted lake Varpan. Mine wastes account for most of the metal that is discharged into Tisken. The hypotheses was that the heavy metal pollutions in lake Tisken influenced the species composition, abundance and diversity of the macroinvertebrates. Twenty samples were taken in both sites.

Visuell informationshantering i tunga fordon : Behovsanalys och förslag till förbättringsåtgärder

The flow of information in road vehicles intensifies as new techniques develop. Informationsources such as cell phones, navigation equipment and radios demand the driver?s attentionwhile he or she must stay focused on the road to perform a safe driving. Today the visualinformation inside the vehicle is mostly located on the dashboard, which forces the driver tolook down when shifting attention between the environment outside and the informationinside the vehicle. One way to avoid this is to useHead-up Display (HUD), a technique thatprojects information in the visual field of the user.This master thesis has been performed in cooperation with Scania CV AB, a world leadingtruck producer.

Öppen dagvattenhantering i urbana miljöer :

Storm water causes a number of problems in our country, particularly in city environment with its surfaces of non-absorbing ground materials. At heavy rain falls there are floods due to lack of capacity in the drain system when meeting heavy water masses over a short time. When the drain system is overloaded huge water masses reach the recipient untreated and there causing disturbances in the aquatic ecosystem. Due to emissions from mainly traffic, industries and other human activities the storm water is polluted. Earlier the problem used to be solved technically, by increasing the capacity of the tubes and by construction of reservoirs to delay the floods peaks.

Together we can rock´n´roll : Status Quo- en studie av ett rockbands karriär

The main purpose of this essay is on one hand to try to find and explain the formula of success of the rock group Status Quo, and on the other to elucidate and explain the foundation and essence in the music made by Status Quo, but also to study how, if and why the foundation and essence have changed over the years. The method of investigation is partly based on a musical analysis of three albums from three different periods: Hello! (1973), Ain´t Complaining (1988) and Heavy Traffic (2002), and partly on a sociological study of the group?s career between 1962 and today, 2005.The first part of the essay concerns the period between 1962-1973 with an analysis of the album Hello!; the second part concerns the period 1974-1988 and the album Ain´t Complaining; finally, the third part concerns the years between 1989-2002 with an intensified analysis of the album Heavy Traffic. In the forth part of the essay I discuss the career of Status Quo from a sociological point of view.I run to the conclusion that the essence of Status Quo is the boogie-woogie comp on Fender guitar by Rick Parfitt, the riff on Francis Rossis´ Fender guitar in combination with the base, the piano and the drums. This has been the essence through all the years, even though it was more difficult to apprehend it during the 1980s.
