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.

Älvdalens Savings Forest was formed in the late 1800's. During this time the country was conducting the first major land reform in Sweden, namely the redistribution of arable land through government action. In Älvdalen people saw an opportunity to form Savings Forest, that is jointly owned forests, where everyone would get part of the proceeds. The yield in the first place would cover were costs to manage and monitor the forest and to the measures to ensure regrowth and improve the forests. You could also use the proceeds to develop the area and make it easier for the population to manage their forest. In early summer, a survey was sent to all the members of Älvdalens Savings Forest.

Water is an important food and an important natural resource. In order to protect these are the Environmental Code and the EU directive given to water protection and related water protection regulations will be established for all water sources until 2010. Those who will prepare a water protection and related water protection regulations is the municipality or person responsible for water supply. The person then decides and declares the area as water protection and related water protection regulations are municipal or provincial government. The idea of creating a water protection is to protect the water supply and the body of water against pollution caused by point sources, diffuse sources and accidents combined.

Biodiversity is under threat in Sweden and many species are on the brink of extinction. This is mainly due to the large-scale drainage projects during the 19th and 20th century and the increasingly intensive land use in agriculture and forestry. The intensive land use with sharply defined boundaries between the production units has in many cases led to either overgrazing or overgrowing. As a result many species have been pushed back to "leftover" habitats like shooting ranges, power line corridors, roadsides, dumps, embankments and other similar areas. Therefore the question has been raised, wether or not it is needed to re-introduce large herbivores into the wild in order to maintain the biodiversity that is related to the extensive land use.This study has been conducted as a literature review and will focus on the European bison?s (Bison bonasus) impact on other species and biodiversity; conditions for reintroducing large herbivores in Sweden are also discussed.Free roaming populations of large herbivores have a positive impact on plants, insects and many other groups of organisms.

This is a qualitative study designed to investigate how professional support group leaders talk about their role as supervisor of support groups for children and adolescents with problematic home situations. We also examine how these supervisors talk about the method they use and how they talk about the individual child. We have chosen critical discourse analysis to help us explore if there are different ways to talk about these territories. Our questions are:How does the support group leader talk about his role?How does the support group leader talk about the method?How does the support group leader talk about the individual child?The theories we have chosen to use in the analysis of our material is Aaron Antonovsky's Sense of Coherence and social constructivism.

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

This essay describes some factors that may effect small business survival in relation to becoming a supplier for bigger companies that may implement the use of EDI for electronic invoicing.The purpose of this study is to analyse and evaluate what impact may occur during the introduction of EDI between small and big business.Following on from the introduction of methods used in this study there will be a complete analysis made detailing results.From our research we have found that most small business have developed a professional working relationship between themselves and their clients.The adoption of EDI by big business has revolutionised the day to day dealings between both supplier and consumer in that EDI has empowered both chains to collaborate data in real time.In conclusion our research illustrates that in order for small business to survive the must implement EDI. The results of our study have shown that the introduction of EDI to both small and big business has had a positive outcome..

This thesis evaluates the environmental performance of six different fish farming systems. The thesis is part of the network group ?Hållbar fiskförsörjning I Stockholms län? (HFFS) which tries to increase the domestic and regional production of fish in Stockholm and move to a more sustainable supply in the Stockholm county. Two of the chosen systems; pangasius from Vietnam and salmon from Norway are delivering a substantial part of the fish consumed in Stockholm today, although they are very different when it comes to system characteristics. One system, arctic char with conventional feed, is produced in a fairly small scale in the north of Sweden, while the three remaining systems are viewed upon as possible options to supply Stockholm with fish in the future.

This study was an assignment for the company Holmen which is located in the region of Örnsköldsvik, Sweden. The study was focusing on the responsibilities of a forestry planner during the planning season. The study was investigating about how much time the planner spent in the office, in the car and out in the forest. Any other issues that would cause delays were also identified. To be more effective and to increase the number of objects to a district bank, a better preparation in the planning stage (for thinning?s or clear cuts) is needed as well as faster transition on to the next area.

Hylocomium splendens (Glittering wood-moss) is a common species in the Nordic countries and can be found in many different types of boreal forests. It usually forms dense moss carpets on the forest floor. The shoots grow in segments and new segments form annually on the previous years growth. The size of the segments is probably regulated in a high extent by local micro environmental conditions. Previous experiments suggest increased growth of H.

Bakgrund och problem: ?What gets measured gets done? är ett välkänt ordspråk inom prestations-mätningsområdet. Den primära rollen i prestationsmätning är att säkerställa att företagets mål upp-nås och för det används mål och mått som hjälper medarbetarna att prestera väl. Detta gäller såväl i företagets supply chain som i övriga delar av verksamheten. Eftersom en supply chain i många fall är mycket komplex ökar betydelsen av styrning och mätningar.Syfte: Syftet med denna studie är att i detaljhandelsbranschen identifiera ett fåtal Key Performance Indicators (KPI) för en supply chain (SC) som kan bidra till ökad lönsamhet via materialanskaffning, lager och butikspåfyllnad.Avgränsningar: Studien avgränsas till ett företag för att kunna gå på djupet och se hur fallstudiens företag ställer sig till studiens generellt uttryckta syfte.Metod: En kvalitativ fallstudie har genomförts.

The study has shown that retailers in the mid-price segment differentiate their brand through developing a strong company identity around the brand. The personality involves store atmosphere, merchandise and advertising. Larger companies have chosen to lay the responsibility on management level, which facilitates on store level. By controlling the strategies on a central level the company can make sure that the stores are steered in the direction that the company wants them to be steered in, and also that they follow the positioning-concept. The company can also devote its efforts to working with its core value, which is service.

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Sydved and the aim of the work was to investigate the economical output of removing understorey trees before first thinning. Four treatments were studied. - no cleaning before thinning - cleaning of all trees less than DBH 5 cm before thinning - cleaning of all trees less than DBH 7 cm before thinning - cleaning of all trees less then DBH 9 cm before thinning The result shows a decrease of the cost per m3 for the harvester with about 38% if all trees less than DBH 9 cm was cleaned before thinning compared with the un-cleaned area. At the same time the total net revenue increases with about 22%. .

Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.

The contribution of biofuels to the total consumption of energy in Sweden must increase to 49 % in order to meet the goals for the year 2020 set by the European Union. In order to do so, improved information systems are needed to support the business processes within delivery scheduling between customers and suppliers.Enterprise Architecture (EA) is a concept to enable the alignment of Business processes and Information Systems. EA is the framework for the architectures of business, information and applications. With a comprehensive view of the architectures, an Information System aligned with the Business processes can be enabled. The first step in the development of an Information System is documenting the business processes.The goal of this study is to clarify a generic sequence of activities performed within the delivery scheduling process and the information needed to perform the activities.Data for the study was collected through qualitative interviews, first through a meeting with the respondent and after that a following telephone interview with in total 5 suppliers and 6 customers of biofuels.
