As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..

The wastewater treatment plant at GE Healthcare's facility in Uppsala deployed a three step vacuum evaporator in 2007. The purpose of this was to pre-treat wastewater containing amines. The purpose of this thesis was to optimize thisprocess by reducing the amount of concentrate without releasing more nitrogen tothe environment and to examine if density could be used as a measurement of whenthe process should be ended.To create a foundation for optimization six test cycles were conducted with samples taken from all three steps. Both concentrate and condensate were tested as well as the incoming solution. Furthermore, the thesis has been expanded with a benchmarking part examining two different evaporators.

Active ownership is widely regarded as positive for the development and performance of businesses. In this paper, we investigate the impact of ownership concentration and owner identity on return on equity (ROE) in Swedish companies between 1986 and 2008, and show that active ownership might suffer from opposing effects. We find evidence, albeit weak, that ownership concentration has a positive effect on profitability, but that it levels off at high levels of ownership shares. Furthermore, we propose that family ownership has a negative effect on profitability. Our results are dependent of choice of statistical method, but show nonetheless a need to reevaluate what seems to be a universally positive view of active ownership..

The purpose of this paper was to carry out and evaluate a pedagogic ICT-project, where the computer was implemented in art class. Focus was on the consequences of collaboration and also on the students? understanding of their own performance, compared to techniques in traditional art class.The study was qualitative and began with studies in literature. The contents of the literature are the foundation of the discussion, especially theories concerning the learning process, IT and computer-based learning. In the project, three different groups of students from upper secondary school attended and they where given tasks to solve in the image editing program Paint Shop Pro.

Safety and risk management currently have a starting point based on the negative outcome of safety, thus the lack of safety. The starting point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

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.

The purpose with this bachelor thesis is to identify risks and insufficiencies concerning the production at WilloMaskin AB. The project is limited to only 4 machines, where theories as ?OEE? (overall equipment efficacy) should be illuminated and analyzed. The theory of ?Single Minute Exchange of Die? is also presented.The method used in this project is mostly based on qualitative studies but also quantitative studies are presented.

Starting in January 2007, capital adequacy of internationally active banks will be regulated by the new Basel Capital Accord, International Convergence of Capital Measurement and Capital Standards ? a revised framework, [Basel II]. The framework introduces for the first time minimum capital requirements for operational risk and encourages market discipline of capital adequacy by initiating requirements for public disclosure of quantitative and qualitative information on operational risk exposure. This thesis examines the nature, definition, management and public disclosure of operational risk in Scandinavian banks based on regulations and recommendations presented in Basel II. We find that the models currently available for addition of operational risk to the capital requirement do not reflect actual operational risk exposure of banks.

Vi tar vår utgångspunkt i skolans roll som förmedlare av demokratiska värderingar. Vi studerar olika sätt att se på begreppet demokrati och problematiken i relationer mellan demokrati och skolan. Vi använder ett konstruktionistiskt perspektiv, där vi betonar vårt förhållande till forskningsprocessen. Vi betonar även svårigheterna i att särskilja delar i uppsatsen, så som metod, teori och empiri.Vårt syfte med uppsatsen är att problematisera relationer kring demokratibegreppet i gymnasieskolan, främst i relationen till betyg.Till empiriproduktionen har vi använt oss av tre samtal med personal på en gymnasieskola i Malmö. Vi har även studerat texter som Lpf 94, Värdegrundsboken och en rad debattartiklar.

Purpose: The purpose of this paper is to examine if companies? incentive programs for employees is designed in such a way that it makes it possible for managers to reach their goals. Method: Qualitative with a semi standardised questionnaire Results: Our results is that the incentive programs for employees in their present form don?t give the companies a good possibility to effect the employees to perform towards the goals of the system. The performance measures in the incentive programs for employees is suitable in comparison with the goals of the program but the construction and the use of the systems doesn?t give a satisfied result in comprising with the goals.

 Pain is common among women undergoing first trimester surgical abortions. At the postoperative unit, department of gynaecology, University Hospital, Uppsala, the goal is that 80 % of the women should rate pain as £ 3 on a numeric rating scale (NRS), when leaving the unit.The aim of the study was to investigate how rating was performed at the unit and to investigate patient?s perceptions of pain after having undergone first trimester surgical abortion.20 patients (74%) participated in the study. Ninety percent of the patients rated their pain as NRS £ 3 when leaving the unit. Seven patients (35 %) rated their pain as NRS > 3 directly after operation, and 2 (10 %) patients NRS > 3 when leaving the unit.

A variety of demands have to be considered in the design of a new opera house in Galärvarvet. All possible viewpoints are important to be aware of, as is the need for the new building to be a contrast to the already existing opera house in Stockholm. The restricted site also makes a multitude of demands on the building's design.By rationalizing the layout and structure and also by making the footprint smaller, the complex building of over 30 000 square meters can be fitted and blended into the existing physical context. Unlike the existing opera house in Stockholm, the new opera house shows the rationality and the advanced technology that lies behind the scenes and becomes the character of the entire building. Through the dynamic façade, the new opera can convey any character it so desires, just like scenes do through different settings.

At Saab Aerospace in Linköping, components for measurement systems to the fighter aircraft JAS 39 Gripen are developed. In this activity you sometimes want to record the traffic transmitted on the data busses that connects different sys-tems. This traffic on the data busses is using the military standard MIL-STD-1553. This project has aimed to create a system for recording and sending 1553-data. The system is used on an ordinary personal computer, equipped with a recon- figurable I/O card that among others has a programmable logic circuit (FPGA).

Cultivation of grapevine is novel under Scandinavian conditions. We studied the impact of ground cover on frost hardiness of grapevine cultivars in Northwestern Scania in a two-factorial trial with four cultivars Solaris, Pinot Gris, Siegerrebe, Ortega and three kinds of ground cover (open soil, plastic cover and gravel). The study was conducted in a grapevine orchard, planted in May 2009, in Broddarp on Bjärepenisula Sweden (N latitude 56°; longitude E 12°). Soil and air temperature were monitored continuously. Frost hardiness measurements were performed every second week from late September to early December 2009. Frost resistance, LT50, was determined by electrolyte leakage measurement of the upper stems after artificial freezing at -15 °C.
