Nästan alla stålkonstruktioner måste rostskyddas. Undantaget är de som står inomhus i torr luft. Ett rostskydd kan utföras på flera olika sätt, men de vanligaste är att stålet målas med rostskyddsfärg eller att det varmförzinkas. Innan detta kan utföras måste stålet förbehandlas. Det är viktigt att den utförs noggrant för annars kan kvarvarande föroreningar börja rosta under färg- eller zinkskiktet.

SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational. The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.

Abstract Semester and year: Spring, 2008Writers: Victor Andersson and Filip ForslundTutor: Thomas HelgessonProgram: Marketing program, Halmstad University - School of Business and EngineeringTitle: Differentiation from a consumer perspective - How important is differentiation from a consumer?s perspektive when choosing a residence?

Kameraövervakning har ökat kraftigt under de senaste åren, under en dag fångas vi av ett fler-tal övervakningskameror till exempel i kollektivtrafiken, på gator, i gallerior och på arbetsplatser. Huvudsyftet med kameraövervakning ska vara att förebygga brott, förhindra olyckor och därmed jämförliga ändamål. Vid tillstånd av kameraövervakning är det Länsstyrelsen som gör en bedömning huruvida syftet med kameraövervakning väger tyngre än den personliga integriteten. I många fall nekas kameraövervakning just på grund av att syftet inte väger tyngre än den kränkning som sker på den personliga integriteten. Undersökningar om vad allmänheten anser om kameraövervakning är få och är dessutom några år gamla. Vi har därför valt att genomföra en mindre undersökning om vad civilingenjörsstudenter vid nio olika högskolor/universitet i Sverige anser om kameraövervakning på allmänna platser. Undersökningsfrågorna handlade till största del om inställning till kameraövervakning på allmänna platser rent allmänt men även studenternas inställning till kameraövervakning och den personliga integriteten. Undersökningen visar att majoriteten av civilingenjörsstudenterna som svarat på enkäten an-ser att det är positivt med kameraövervakning och 54 % anser även att fler platser bör övervakas, framförallt kollektivtrafiken, bankomater, nattklubbar/krogar, parkeringsplatser samt platser där brottsstatistiken är hög bör övervakas. Efter denna genomförda undersökning, som visar en positiv inställning till kameraövervakning, rekommenderar vi att en större undersökning bör genomföras för att få en bild av allmänhetens inställning till kameraövervakning på allmänna platser och personliga integriteten och se om man eventuellt kan lätta på lagar och regler för tillstånd för kameraövervakning på allmänna platser..

This degree project has been carried out by Niclas Andersson and Sebastian Zwahlen, students of the Innovation and Design Engineering Program at the Faculty of Technology and Science at Karlstad University.

Mavis gave the group the task of developing a new bedroom product. To assess the needs and problems of bedroom behaviors, an extensive questionnaire and several interviews were made. This became the starting point for further work.According to the results uncovered during the market research a vast problem was found with temporary clothing storage.

The content of the following report is the summarized result of three students thesis at Blekinge Institute of Technology in co-operation with Water Jet Sweden AB. This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

AbstractThe Energy Declaration is a law that will come into effect October 1: Th 2006. This report has Värnamo municipality as principal and shall clarify what the estate owner in general and Värnamo municipality in particular need to know about this law. Another part that is going to be dealt with is how large the future need for energy experts in this field will be, and which competence that will be demanded for them.The work will in general deal with simplified energy declarations for apartment houses and public buildings, since these buildings are the first to be involved with energy declarations.The energy declaration will consist of a number of important components.? Energy power i.e. how much energy the building consume? If the ventilation control is done? If the radon measurement is carried out? Recommendations of measures to improve the energy power? Reference value to compare the buildings energy power againstAccording to the law the declaration shall been made by an independent expert, which will need certain information for this.

Since their invention in 1999, CubeSats have become a widespread standard for small picosatellite missions. CubeSats allow for quick development of satellite payloads and launch in space without the high costs of a normal satellite. Emphasis during the CubeSat design process is placed on use of commercialoff- the-shelf (COTS) components and reuse of previously-designed units.This report describes the interfacing of a scientific magnetometer, the Small Magnetometer in Low-Mass Experiment (SMILE) to such a CubeSat mission, the Space Weather using Ion spectrometers and Magnetometers (SWIM). Design of a complete platform for use in multiple such missions is presented here.Modularity is one of the key aspects followed in the course of the work. A new board containing the analog pick-up and compensation circuitry for SMILE has been designed to fit inside a CubeSat frame.

Through extensive research it has shown that today?s sail boat owners are very frustrated concerning the limited choice of engine alternatives offered by today?s market. Besides rising fuel-costs, environmental awareness is very important in today?s society. Hence it is vital to find alternative environmental-friendly motors and replace combustion-engines. Zilent Ocean is an extensive project within Development engineering program at Halmstad University.

Presently Sjöfartsverket do their maintenance according to a standard program, which means that every maintenance task will be done when the task limit occurs. This leads to a very long downtime for the aircraft in some occasions and very short downtime in others. The goal with this work is to reach a higher regularity of the aircraft operation. To reach a higher regularity for the operational needs, this work will present a hypothetic better maintenance concept for Swedish Maritime Administration. The concept is based on equalized maintenance structure, which means that every maintenance occasions are meant to take the same time to perform.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

This report was made for the company HordaGruppen AB to investigate how information security was handled. This report fits in the Master program of Internet Technology at School of Engineering in Jönköping University in Sweden.The question at issue was how you protect your information against different threats. One question was how to make an information security policy and which guidelines you can follow in the Swedish Standard, SS-ISO/IEC 17799:2000.Another question was to investigate the information sources at the company and which threats there are against it.The work begins with a presentation about information security for the chief of information and the chief of quality in the company. The next thing was to do a survey of as thing are at present with a tool from Länsteknikcentrum called ?Infosäkpulsen?.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

The division of Electricity at Uppsala University runs a project called Lysekil project, they have designed a buoy that uses the waves to create electric power from a generator attached to the bottom of the sea.Uppsala University is closely connected with the company Seabased and the university makes use of their facilities in Lysekil. When they designed the buoy issues occurred, the geometric design was flawed, brackets with a short shelf life and it is generally uneconomic.A study visit was done in Lysekil on Seabased facility. With this visit the project started, which is to improve the design of the buoy and the attachment of wires leading to the generator. In this project we have chosen to use a beam system with three beams that are attached to the buoy. Then a wire attached to a plate that sits between the beams will be leading to the generator. Two proposals for construction are created, what distinguishes them are the brackets between the beams and the buoy.From these constructions, the design that is considered most optimal for our project is chosen.All parts of the buoy have been modeled and the drawings are designed in ProEngineer software.The two constructions are compared with each other, but the whole focus is on the second and final structure. The report begins with an introduction describing Lysekil project, and a task description of our project.The project aims to produce an optimal buoy that will be easy to design, materials restrictive with good durability and an economical solution.Wave power true function has been studied, mechanical and finite element analysis of beams, buoy and plate design.This has been presented in this report, where in the various chapters can read more about the processes. Although the relevant facts and information on this project and buoy development is included.

With background in the rapidly growing need to find solutions for sustainable energy production and the increasing interest for wind power, this report was written. With take-off point from the wind power plant Big Glenn, which has been built in the harbour of Gothenburg, a model of the adjacent power grid has been created in Simulink/SimPowerSystems. Parameters for the power grid and its components has been provided by Göteborg Energi Nät, that has also been the supplier of measurement data of produced power, the power need from loads in the vicinity, voltage levels, current values and also the variation of power factor at the wind power plant.The SimPowerSystems model has been used to perform simulations of power flow in the grid. These simulated values have then been compared to the measured values to verify the functionality of the model. Further, the model has been used to perform simulations of a grid fault, which causes a voltage drop.
