The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Målet med detta arbete är att hitta en lämplig lösning för lastsimulering vid test av bussar.Projektet utfördes i samarbete med Laxå Special Vehicles (LSV) som ska bygga entestbuss åt Scania.Scania har tidigare en testbuss med ett lastsystem som ska bytas ut när det ska byggasen ny testbuss. Uppgiften i detta arbete blir att ta fram och utveckla ett helt nytt lastsystemför den nya testbussen. Information om den buss som ska byggas har samlats in ochutifrån detta har via brainstorming framkommit flera möjliga lösningar som sedan harutvärderats.Metodiken som projektet arbetat efter är systematisk konstruktion enligt Johannesson,Persson och Pettersson (2004). Denna metod kan delas in i fem steg,Produktspecifikation, Konceptgenerering, Utvärdera koncept, Detaljkonstruktion ochslutkonstruktion.Det lastsystem som Scania använder idag har några nackdelar, bland annat att det ärbesvärligt att ställa om systemet från ett lastläge till ett annat. Samt att det under vinternär problem med att systemet fryser då systemet använder sig utav vatten somviktmedium.Ett av de lösningskoncept som tagits fram valdes att arbeta vidare med till enslutkonstruktion.

Aqeri has since the past year a new profile with name and logotype, which has createda need for an updated visual product identity. The company is a leading developer,producer and distributer of IT products suitable for extreme environments in industry,defense and vehicles. This new profile with the different segments has together with aproduct identity from two companies resulted in that they have no clear designidentity on their products. From this background the aim of this research is todetermine how a development of a design identity is done to implement it to Aqeri.The design identity can be defined as a product?s identity visualized through its formor appearance which defines what the product is.

Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..

This masters thesis concerns a modeling project performed at Volvo Technology in Gothenburg, Sweden. The main purpose of the project has been to develop a physical model of the climate in construction vehicles that later on can be used in the development of an electronic climate controller. The focus of the work has been on one type of wheel loader and one type of excavator. The temperature inside the compartment has been set equal to the notion climate. With physical theories about air flow and heat transfer in respect, relations between the components in the climate unit and the compartment has been calculated.

There exists a great need among companies and other organizations to be able to visualize statistics. It?s also increasingly common to ask for web-based solutions for increased flexibility and accessibility for users. This paper describes how large amounts of geovisual data, for a large number of regions, can be visualized in an interactive and well-presented manner. The paper let?s you walk through two application scenarios, developed in a Flash environment, using the GeoViz component library for visualization. The first application has been developed for Statistics Sweden (SCB), to give a solution on how to visualize statistics for Sweden?s zip code regions.

Lödfogar på kretskort utsätts för spänningar i samband med temperaturväxlingar. Dessa spänningar leder så småningom till utmattningsbrott. Omställning till blyfri lödning  pga EUdirektivet ELV (End of Life Vehicles) som inom kort kan börja förbjuda användning av blyhaltiga lödfogar även i tunga fordon, medför en ökad risk för utmattningsbrott, eftersom blyfria lödfogar påstås vara sprödare än tenn/bly lod. Scania har begränsad kunskap om eller erfarenhet av blyfria lödfogar och har av den anledningen startat detta projekt.I det här projektet vill man ta reda på ifall påståendet ovan, om att blyfritt lod är sprödare än blyat lod, stämmer och för att kunna göra en sådan jämförelse mellan loden måste dessa analyseras från ett materialtekniskt perspektiv. Scania har fram till nu fastställt sina provresultat via ett elektriskt funktionstest.

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.

This report deals with handling and interim storage of soils which are planned tobe reused in construction works. The types of soils that are dealt with are gravel, topsoil and sand. The thesis work has been carried out in collaboration with Skanska Sverige Väg och Anläggning Sydost. The main goal is to find an area for using to store soil in between projects.Studies of laws and regulations regarding exploitation and storage of soil has led to a theoretical background upon which the report is based. Background informationhas also been gathered in meetings with the employees at Tekniska Kontoret and Länsstyrelsen in Jönköping.On the basis of literature studies results, a general template has been developed for which desirable properties a possible location should meet.The model was applied to find a number of possible options in the vicinity of Jönköping.
