LIN baserad kommunikationsmodul för GPS

The work that is the basis of this Master Thesis was performed on Scania´s group of cabdevelopment, and concerns the GPS-system in Scania´s trucks. Today, the GPS-systemconsists of an active antenna mounted on the roof of the truck. The antenna is connectedto the receiver with a coaxial cable.The purpose with this Master Thesis was to develop and evaluate a new GPS-system,where the information is distributed using a LIN-network. Today, each unit requiringGPS-information is equipped with its own antenna and receiver. This solution has beenthe most cost effective to this point.

Analys av fördelningssystem för bostadshus

The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

Framtidens Hus

The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..

Partnerval i joint ventures på den svenska 3G-marknaden En studie av de svenska nätoperatörerna

Background: Traditionally defined boundaries and borders between organizations are at present being re-evaluated because of new and tougher demands. Today we can see a trend where these boundaries are being lowered or even eliminated when organizations choose to co-operate instead of compete. Purpose: In order to create an understanding for the partner selection process in the newly founded joint ventures between the companies which are building the Swedish 3G Network, the determining factors are being studied. Delimitation: The studies companies are co-operating as network operators but are at the same time competing as mobile operators. This relationship is in the literature described as co-opetition, which will not be investigated in this paper.

Linjenätsutredning i Täby kommun.

The public transport network in Täby commune consists currently of two types of bus line of whichboth belong to the category of feeder lines. The first type terminates at Danderyds sjukhus and feedsto the subway whereas the second type terminates at Täby centrum and feeds to Roslagsbanan, asuburban narrow-gauge railway system in northern Stockholm. The trunk bus line that connectsgreater parts of the commune with Danderyd is the ring line 604 and goes both clockwise (604H) andcounterclockwise (604V). The main negative aspect of this structure is the complicity in incorporatingit timetable-wise with other bus lines that share the same route, such as through Enebyberg.The goal of this project is to investigate the possibilities of splitting ring line 604 and connecting theends to two different bus routes that terminate at Täby centrum today. Apart from easing thecoordination with other bus lines through Enebyberg, the extension also creates new directconnections from various areas in Täby to Danderyds sjukhus.

Ensamkommande flickors migration : En komparativ analys av Afghanistan och Somalia

Sweden is the country in Europe that receives most applicants from asylum seeking unaccompanied children. The majority of all unaccompanied children are boys and the two biggest sending countries are Afghanistan and Somalia. There is however a big difference between the proportion of unaccompanied girls between the two countries, Somalia with a big proportion of girls and Afghanistan with a low proportion of girls. Previous research has shown that there is a big knowledge gap about unaccompanied girls? migration.

Samverkan mellan sociala företag

AbstractTitle: Cooperation between social enterprisesLevel: Final assignment for Bachelor Degree in Business AdministrationAuthor: Anna HammarbergSupervisor: Maria Fregidou-MalamaDate: 2012 - JanuaryAim: The aim of the study is to investigate social enterprises and the Glada Hudik-model to understand how social enterprises cooperate and how they can develop the cooperation through Social Enterprises in Co-operation (SAK). Method: I have done a qualitative research study. I have studied literature to get theoretical background. I visited a seminar to get information and inspiration. Interviews have been done with six persons to get empirical information.      Result and conclusions: Through this study I have seen that social enterprises can co-operate to strengthen their position in the community. Together they can run issues they have in common, undertake major assignments and purchase material to get better deals.


Hur fungerar logistiken i produktionen på ett byggföretag?

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

Spatial TDMA in Ad Hoc Networks with Antenna Arrays

In modern military operations the requirements of transmitting large amounts of information have increased substantially during the last decade. This increases the demand for high-capacity radio networks. It is also very important that military decisions are made on recent and correct information and this implies that low and known delays are required. The existing military radio ommunications, within the Swedish army, do not meet the requirements for capacity and delay. We have investigated how the capacity and average delay can be improved in an Ad Hoc network with STDMA by using antenna arrays.

Not Quite på två ben : En studie av synen på kulturkooperativet Not Quite's roll för lokal och regional utveckling

For the past decades, culture has been given a role as a factor for local and regional development. But what is meant by development and in what ways culture can be of importance in this aspect can be unclear. This thesis examines the perception of the role for local and regional development of one specific cultural place and network ? the cultural cooperative Not Quite in Fengersfors, Sweden. I study the way the role as developer is expressed and interpreted in the discourse of the cultural workers who are members of the network and in the discourse of public cultural policy in the region Västra Götaland and in Åmål municipality.
