SammanfattningFöretaget Bedsab tillverkar dragstrumpor som är ett verktyg som andvänds för att underlättaförflyttningen av vajrar. Den mekaniska funktionen av en dragstrumpa är sådan att vidtryckspänning fås en större diameter och dragstrumpan kan då föras över vajeränden. Viddragspänning får dragstrumpan en mindre diameter än den ursprungliga vilket innebär attdragstrumpan ?låses? kring vajern och kan med hjälp av en applicerad kraft förflytta vajern tillönskad plats. Hos företaget Bedsab sker tillverkningen av dragstrumporna för hand vilket äroerhört slitsamt för operatören men även mycket tidskrävande.Detta examensarbete bygger vidare på ett tidigare projekt där en automatisk flätningsmetodtagits fram för tillverkning av dragstrumpor.

För tallen finns många alternativa slutanvändningsområden, och kraven på virket varierar. Några egenskaper som har stor betydelse är stamrakhet, grengrovlek, grenvinkel och om det finns sprötkvist eller ej. Kvalitetsförsämringen i Sydsveriges tallskogar kan vara ett allvarligt problem och härör bl.a. till ökad produktion och rationaliseringar inom skogsbruket. Lönsamhet har varit målet, men har det skett på bekostnad av kvalitet?För att närmare belysa frågan om förekomsten av tall av god kvalitet syftar denna studie till att bedöma rotstockar i konventionellt skötta och stamkvistade bestånd samt deras potential att växa in i värdefulla klasser eller sortiment.Fältstudien är avgränsad till Bergslagen.

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.

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.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

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..

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.

This MSc thesis is divided into two parts. The first part deals with the need for information from forest campartments selected for clear cutting, in connection with planning in an integrated forest- and sawmill enterprise. A review of literature is followed by a case stud y, where present conditions in a Swedish forest company are compared with current research in the area. The seeond part consists of a simulation stud y, which aims at camparing the accuracy of inventory estimates using different methods. The estimates are delivery forecasts, covering one month consumptian of timber in a large sawmill.

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.

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.

Denna studie behandlar tillväxt och beståndsstruktur samt sambandet mellan dessa i skog skött med blädningsbruk. Blädningsbruk förutsätter fullskiktad skog med fallande diameterfördelning, under nordiska förhållanden vanligtvis dominerad av gran (Picea abies (L.) Karst). Strukturen i fullskiktad skog är resultatet av tillväxt, skörd/mortalitet och inväxning. Kunskap om det komplexa samspelet mellan dessa faktorer ger skogsskötaren möjlighet att planera och sköta fullskiktad skog för en hög och uthållig produktion. Undersökningar och litteratur inom aktuella områden tas upp i en litteraturstudie. Ämnen som behandlas är: definitioner och begrepp, diameterfördelningen i fullskiktad skog och hur denna kan beskrivas, blädning och andra avverkningsstrategier samt tillväxt- och produktionsundersökningar i Norden, Europa och USA.

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.

Varje år genomför Södra skogsägarna gallringsuppföljning av samtliga maskinlag som gallrar för Södra. En del av bestånden som blir uppföljda har en låg grundyta efter gallringen, utan att de har blivit gallrade hårt. Målen med rapporten var att undersöka om dessa bestånd har några särskilda egenskaper som gör att man kan identifiera dem före gallring och undvika att de blir för glesa samt studera effekterna av ett glest bestånd. Totalt inventerades 19 granbestånd som blivit första gallrade och inventerade för fyra eller fem år sedan. Vid den tidigare inventeringen så hade tio bestånd låg grundyta och nio hade en normal grundyta efter gallringen. Vid inventeringen klavades samma träd i brösthöjd som vid det första tillfället, vidare mättes höjden på det grövsta trädet på provytan-. Södra nyttjar simuleringsverktyget INGVAR för att skatta tillväxt och se gallringsbehov.

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.
