Funktionsutveckling av ett UGV operatörsgränssnitt
Examensarbetet syftar till att konstruera operatörsgränssnittet till en UGV (eng Unmanned Ground Vehicle) för mobil rekognosering i tätbebyggt område. Operatörsgränssnittet består av både mjuk- och hårdvara. Till operatörsgränssnittet har ett grafiskt användargränssnitt utvecklats där tonvikten legat på användbarhet med funktionalitet för positionering med geografisk presentation och sensorpresentation. Förutom en presentationsenhet för sensorinteraktion och manövrering av farkost ingår en sändtagarenhet för kommunikation mellan operatör och farkost. Två uppsättningar av systemet levererades till försvarsmakten för användning vid metodförsöksstudier..
Undersökning av fosfatsbegränsningseffekter på Escherichia coli AF1000 för bättre förståelse av 3-hydroxybutyratproduktion
High quality within a Lean production system begins with standardised work, which creates stable processes able to generate predictable output. If nonconformity from the standard procedures occurs, routines are needed to analyse, correct and prevent the nonconformity from occurring again. In that way, the nonconformity can be a trigger for continuous improvements toward more stable processes. In takted production lines, where the operator follows a standard sequence with tasks set to be completed within the takt time, a nonconformity leads to downtime in the operator?s sequence, and no value is added.

Insatser och åtgärder för främjandet av laddelbilar i Sverige
To achieve the goal of fossil independency in the Swedish vehicle fleet in 2030, it would be important to substantially increase the proportion of electric vehicles, both BEV:s (Battery Electric Vehicles) and PHEV:s (Plug-in Hybrid Electric Vehicles). The Swedish Energy Agency has funded numerous research and development projects about electric vehicles in recent years. An important task for the Swedish Energy Agency is to allocate state funds to those projects with the greatest potential to contribute to increased establishment of electric vehicles in society.
The purpose of this work is mainly to understand the efforts and measures that can make the market for electric vehicles to grow. The report can contribute to a better understanding of how far the research on electric vehicles has come and what has to be done in the future to promote the establishment of electric vehicles. Another aim for this report is that it should serve as a basis for future decisions by the Swedish Energy Agency on which projects that will be funded with state funds.
Band eller hjul? : Lämpligt fordon för EOD-specifika behov i Afghanistan.
The background to this paper is the events that have taken place in the Swedish area of responsibility in Afghanistan where Swedish troops have been ambushed by the insurgents. Although the troops primarily where riding in Toyota Land Cruisers they had no casualties. I think that the Swedish force needs other vehicles that can be armed and are armoured.When I compared three different types of armoured vehicles, I found that PTGB 6 is the vehicle of choice, according to the special needs that a Swedish EOD-squad, their task and their equipment have. .

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Utformning av målflygplan
Scandicraft AB hade för avsikt att utveckla ett nytt målflygplan som skulle kunna nå Mach 0,5 på 50 m till 5000 m höjd. Detta med jetmotorer avsedda för modellflygplan. Flygplanet utformades för att kunna upprätthålla oaccelererad planflykt i Mach 0,5 på 50 m höjd. Vid analys framgick att flygplanets luftmotstånd var för stort. Flygplanets bränslemängd måste därför minskas från 40 kg till 13 kg.
Autonom UAV
In Abisko National Park there are a numberof weather stations. To be able toretrieve the data from the nodes in thefuture a Quadrocopter-prototype has beendeveloped during this master thesisproject as a first step. A quadrocopter isa helicopter with four rotors placed in across formation. The quadrocopter cannavigate autonomous between different GPSpositionsthat are updated during flighttrough Xbee-modules. All levels fromsources code, design of the electronics todevelopment of the chassis was performedduring the project.
Effektiv byggproduktion
This report aims to suggest recommendations that will increase the efficien¬cy in theconstruction process of a construction project. Through interviews, studies of budgetcalculations and examples given by the project management at the construction sightsan understanding of some complications have been gained. These complications havebeen tracked back in an attempt to find the source of the problem, and at the end ofthe report some suggestions have been presented with the pur-pose of preventingthese complications. Through the interviews it is suggested that many complications re-late to lack ofcommunication and motivation due to poor planning be-fore and during theconstruction process, a suggestion that is supported by the study of the budgetcalculations. The examples from the project management also points out someshortages in planning, but also coordi-nation related complications due to lack ofcommunication. To prevent these problems the recommendations suggested at the end of thisreport aims to improve the planning process through a properly fulfilledwalkthrough-planning of all of the construction activi¬ties during the time needed todo so. It is also suggested that the company uses experience from previous projects inorder to reduce costs, and that the qualifications of the employees is being appliedwhere it is needed.
Framtidens elnät : Hur elbilar och solceller påverkar på det lokala elnätet
The purpose of the project is to determine the impact of solar cells and electrical vehicles on the future electricity grid and distribution network. Future electricity grids will be affected differently than it does today. Therefore, it is important to determine the impacts so that the current electricity distribution system can be developed and redesign to achieve the future demand. In Sweden, government has changed rules and laws in order to make it easier for private sector to invest in renewable energy sources. Our project focused on the impact of the solar cells and electric vehicles on the low voltage electricity distribution.

Grovkrossning av stubbar : en produktivitetsstudie
The Swedish parliament has decided that Sweden should increase its usage of renewable fuel sources to a level of 50% of the total energy consumption in Sweden by the year 2020. One way to reach that goal may be to increase the usage of stumps as a bio-fuel. In Sweden stump harvesting is possible on about 5-10% of the total harvested area and thus contribute with 1,3 - 2,6 TWh per year. An increase stump harvest doesn't come without its drawbacks for the environment. When harvesting stumps a tracked excavator is used to pry the stumps from the ground and then cut the stumps into smaller pieces.
Effektiv provningsmetodik för växelföringsdamasker
Completed durability testing of gearshift gaiters at Kongsberg Automotive in Mullsjö, is sometimes leading to discussions regarding whether or not a gaiter is supposed to be a pass or a fail. That is because the current pass/fail-criterion are a bit vague. A durability test takes around 4-5 weeks to complete which is a long time if the tested material does not pass the test and a new material has to be tested instead. Stricter pass/fail-criterions and a faster testing method for the materials are therefore desired.In order to develop a durable pass/fail criteria, seven already judged gaiters were chosen. Every one of the gaiters was put through detailed analysis, after which there were a new assessment of the gaiters.
