Gulliver Simulation - En systemarkitektur f or n atverkssimulering av
Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.

Ytterväggar och bjälklag för flerbostadshus
The thesis demonstrates protection solutions that can be suitable for a camp during internationalmissions in order to resist complex threats. The threats could consist of small arms, machineguns,RPG 7, anti armour missiles, mortar, artillery, HPM-weapons, car bombs, biological and chemicalweapons as well as sabotage and theft. It?s not the technology itself that makes the threat scenariocomplex it?s the way the opponent acts during the operations. The opponent acts usually incivilian clothes and therefore he is difficult to distinguish from other civilians.
Platsrelaterat själv och autobiografiska minnnen hos svenskar boende i Schweiz
The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.
Miljösystemanalys av VA-system i omvandlingsområden : fallstudie i Värmdö kommun
Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants.
When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

Resultatstyrning på Sida: Ett Sisyfosarbete
This study aims to examine how performance management is compatible with the operations at Sida, Sweden?s International Development Cooperation Agency, by performing interviews with representatives from Sida. The public sector is facing increased demands on accounting, which has emerged as an institutionalized social norm in society. The nature of Sida?s operations, however, proves to be highly complex, rendering results based management difficult to implement.
Ergonomiska förhållanden för mjölkare i olika mjölkstallar :
Earlier studies of musculoskeletal problems with milkers working in milking parlour
operators have shown that it is a physically demanding occupation. The extremities that are
most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in
present cases are fishbone and some tandem barns.
There have been changes in the working environment during the past ten years. The
mechanisation has been developed for the better with automatically removers of the milking
units and vertically adjustable floors in almost every daily milking barn. In other hand the
milk production are more industrialised and more related to stress today.

ABSTRACTThis pilot study examines the knowledge about tree root systems amongst five treeplanting professionals. The aim is to find out the professionals? collective knowledge ofthe nature of root systems of various trees used in green areas. Furthermore; to explorehow the professionals adapt landscaped green areas to the tree root properties in asustainable manner. Questions: Which tree species have special root properties toconsider and how do the professionals utilize this knowledge? And: How do theprofessionals in general adjust planting according to the root systems of trees in areas tocreate sustainable green environments?Interviews with the professionals were performed.
Radioräckviddsberäkningar för flygande plattformar
There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

Folkrättsliga problem vid användandet av adaptivt kamouflage
Adaptivt kamouflage är en signaturanpassningsteknik som ger stridsfordon förmågan att anpassa sin värmesignatur utefter omgivningen eller imitera andra objekts signatur, i syfte att undgå upptäckt eller identifiering.I denna studie genomförs en analys om vilka folkrättsliga problem som kan uppstå vid användandet av adaptivt kamouflage.Studiens resultat visar att de folkrättsliga problem som kan uppstå vid användningen av adaptivt kamouflage är distinktionsproblem, då tekniken möjliggör för stridsfordon att imitera signaturen av civila personbilar. Denna användning av adaptivt kamouflage kan anses som brott mot distinktionsprincipen..
Standardiserande CAN drivrutiner
This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.
