Simulering av översvämningar i Nedre Dalälven

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

Ledarskapets betydelse för medarbetares arbetstillfredsställelse i detaljhandelsmiljö

Attacken den 11 september 2001 mot USA och World Trade Center blev händelsen som startade hela världens krig mot terrorism. I och med detta har flertalet terrornätverk dykt upp och terrorismen har lämnat få människor opåverkade.Detta arbete syftar till att analysera hur attacken på World Trade Center påverkade händelseförloppet i USA och den militära insatsen. Genom att använda John Wardens teori om luftrumskontroll kommer en jämförande studie mellan hur luftstridskrafterna användes under konflikten i Kosovo år 1999 och under den i Afghanistan för att förklara likheter och skillnader.Studien utgår från en kvalitativ dataanalys av rapporter skrivna i direkt närhet till respektive konflikt.Undersökningens resultat visar på ett väl organiserat och standardiserat sätt att utföra luftstrid på. En tydlighet i taktiken där fokus genomgående, i respektive konflikt, läggs på samma sorts mål. Men även tydliga skillnader mellan konflikterna går att särskåda men det påpekas dock att en direkt kausalitet mellan dessa skillnader och attacken är svår att peka ut.Slutligen förs en diskussion kring hur attacken kan ha påverkat den insats som gjordes i Afghanistan genom en jämförelse mellan båda konflikterna.

Energi- och exergiflöden i stålframställningsprocesser vid
SSAB Tunnplåt AB i Luleå

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

Den skamlöse Jesus : Tempelrensning, en kamp om heder

This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.

Migration och vegetationsupptag av radiocesium i åkermark - en långtidsserie av mätdata samt en långsiktig simuleringsmodell :

Abstract The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment. In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.

Fastighetsbolagens val att redovisa till verkligt värde eller anskaffningsvärde : En studie om vilka faktorer som påverkar företag i deras val av redovisningsmetod

 IAS 40 allows two methods of valuation for investment properties, fair value model and cost model. The purpose of this paper is to investigate what drive property companies to disclose their investment properties at fair value. In order to understand their choice, we use accounting choice theory and the three factors this theory describes, information asymmetry, allowing opportunism and agency costs. To answer our purpose, we have from a qualitative approach performed semi-structured interviews with respondents from five of the largest listed property companies in Sweden. The results suggest that firms have chosen the method that is most effective in the valuation of investment properties.

Varning för snabblån - En studie om effekter av varningar i rörlig marknadsföring av snabblån

Payday loans are becoming a challenge of increasing gravity for society. Statistics show that the number of young adults with financial issues related to such loans has been growing over the past few years. Despite efforts to halt this trend, little is changing. Government mandated warning labels in commercials are typically used to inform about the risks associated with the consumption of certain goods and services, such as alcohol and tobacco. Despite issues related to payday loans, there is currently no legislation in Sweden mandating the inclusion of warnings in marketing of such loans.

Dell from a intellectual capital perspective (working title)

Purpose: We will understand and explain Dell?s value gap through an extended intellectual capital theory. This will be done by deriving the value to the different parts of the intellectual capital value scheme. We will also use value scheme to describe the ongoing strategy shift. Methodology: The qualitative method and an abductive reasoning have been employed during the progress.

Fisk, fågel eller mittemellan? : En studie av tre multiprojektmiljöer

Background: A great part of all projects within Swedish industry are conducted in a multiprojectenvironment, which means that several projects are performed simultaneously. The research within the field of project management is though focused on single projects. Projects are highly dependent on the context in which they are conducted, although the organization of the multiprojectenvironment is only partly explored. Furthermore is the research within the project management highly concentrated on standardization of the project work. The question is whether this implies to the basic advantages with the project-oriented organization, which is flexibility and creativity? Purpose: To describe and obtain an understanding for the multiprojectenvironment regarding management control and organization.

The purpose of themanagement model is to describe how the department FATPA wants to work, especiallywith consideration to the department?s management.

Planering : fallstudie av en mjölkgård

The purpose of this paper is to give examples of different ways of economic planning and calculation within agriculcture. My aim is to use a couple of them as an explanation of a case from reality. My choice went to budgetsimulation and balanced scorecard since those are best suited in this specific case. In the information retrieval I present different instruments of economic planning like theory of cost, budget and productcalculation. The budgetsimulation describes how to use the different methods in a long term economic planning. The balanced scorecard is also a model of longand short-term planning but besides the economy planning it?s also a reminder of your personal goals. In the model I have used a dairyfarm as a case.

Operation Rolling Thunder

This paper provides an explanation of the concepts John A. Warden III describes regarding the use of air power and if this theory can be found, within the confines of an unconventional war. The U.S. ability to air power is overwhelming, however the right kind of warfare can force this great power to abandon their military and political objectives by exhausting its resources over time as it becomes increasingly costly, both economically, politically and morally, to wage war. The research deals with operation Rolling Thunder and John A.

Centraliserad personalavdelning- bästa verktyget för chefsstöd? : En kvalitativ studie om arbetssituationen relaterat till chefsstödet från personalavdelningen vid Uppsala kommun.

Changes in the workplace have led to new ways of organizing and structuring organizations. Organizations? desire to increase competitiveness, efficiency and flexibility has resulted in new conditions in the field of human resources. The new conditions have also created new roles and changing responsibilities for those working within human resources.The purpose of this study was to investigate how the implementation of Ulrich's model for HR transformation can impact on the human resource departments managerial support to first-line managers in the municipality of Uppsala. Today the municipality of Uppsala organizes its human resources based on the Ulrich's model, which divides the work into the units service center, the expert unit and business partners.
