Biogasanvändning vid Käppalaförbundets Reningsverk: ? en värdering av miljöeffekter
This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.
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.
Beaker-kulturernas ursprungs-ID
This essay aims to investigate the use of an origin-ID within the Beaker Complex, as defined by John C. Barrett, seen through their different expressions of use in ceramic form and ornamentation, architecture and landscape through time and space with special emphasis on the late Neolihtics in the South of England. The analytic vehicle "the reinforcing circle" is used as a new diffusion model suggested by Stuart Needham, and the analytic tool "incubation" is used to structure the process the Beaker-cultures may have used to reach cultural hegemony. Id est, that the Beaker-cultures socially invites already existing cultures, offering within family and trading the results of new technologies. And/or, occupy the space and use the authority needed by re-writing the narrative as seen in the grave use and grave deposits.
Lägesbild : Problemområden vid skapandet
Within the framework of the concept of Network Based Defence (NBF) services should be available in the network, in order to increase the aggregate capacity. A common situation picture is one of these services.The aim of this paper is to answer the problem "What are the main problem areas in the creation of a situation picture in the land arena, with the help of the technical sensors that exist today?" and to develop a basis for continued research in the field situation in the concept Networking Enabled Command, Control and Collaboration (NEC3) at JCDEC (Joint Concept Development and Experimentation Centre). To answer the problem, a descriptive method is to be used in descriptions of the land arena, the information arena and the sensors and a deductive method is used when analyzing the asensors in the land arena.The problems that exist in the creation of a common situation picture, is that different types of obstacles makes it difficult for the sensors, the large number of people who are not combatants and that it is difficult to judge if a civilian vehicle is a threat, then it could be driven by civilians or by combatants..
Automatiskt avvägningssystem för obemannad undervattensfarkost
This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.
Implementation av FlexRay prototypstack
FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.
Hybriddrift i stridsfordon, fördelar och nackdelar
Petro-electric IFVs (Infantry fighting vehicles) or hybrid-IFV?s are not a new phenomenon. During the 1900?s Germany as well as the U.S both tested vehicles constructed with hybrid technology. In spite of several identified advantages, no serving hybrid-IFV exists today.
Senior Concept Vehicle
We can see an increasing middle age population in large parts of the world. People are healthier when they retire than they were before. As people grow older, physical and mental changes occur that can make the use of cars more complicated. The possibility to travel by car is important for many people to keep the connection with the society and to feel independent. How can Volvo cars face the needs of this growing target group?The purpose of this project is to make a car concept that responds to those needs, it is therefore important to maintain the values of Volvo cars.
Det första könet, dess ?Andra? och den tredje världen : västerländsk manlighet i reseskildringar
Travel literature and especially the ?adventure story? has excited young British boys for over two centuries. However, it has also been a vehicle for the assertion of male dominance and European supremacy. The story of a British man who goes to the colonies, performs some test which is essentially a test of his manliness, and whose compulsory victory marks the end of the book, has been a central myth in colonial masculinity.Through looking at three Anglo-Saxon male travel writers from the 20th century, this essay aims to study the different ways in which Western male identity is shaped against an Indian background. The novels analysed are Topee and Turban or Here and There in India by H.A.
Hur Gud tar sig ton! Om musik som ett skapelsegivet kommunikationsmedel f?r m?nniskans tro.
This study explores how music can be seen as a vehicle for religious faith.
How does music transcend beliefs and messages from God to humans, and how can it be used as a way of interpreting and recognizing the supreme, ultimate existence that people refer to as ?God?? Music has been used as an important expression in religious cults throughout times. It has been used as a healing force, in accordance with what has been said about God's willingness to heal humans. Historical examples include Paul, Origen, St.
Impact of EU-regulation on pigs? welfare during transport
Each year 225 million pigs are transported within the European Union (EU) for slaughter, fattening and breeding. This results in poor animal welfare due to the fact that animals are exposed to several numbers of stress factors in the vehicle during loading, transit and unloading. Animal welfare can be defined as how well the animal attempts to cope with its environment and during transport there is often severe difficulty for the pigs to cope properly. There is a growing societal concern for animal welfare. This resulted in that the European Union enacted a law called the EU-regulation with certain directives of how to improve the welfare of the animals during transport.
Utvärdering av insamlingssystem för hushållens farliga avfall
The collection of hazardous waste from the household around Swedish municipalities varies. 1% of the households waste is hazardous waste. It has hazardous features that can give bad consequences for the nature and human health if we don?t collect it and treat it. Therefore the law controls it, the municipalities have responsibility for the household waste.
The petrol station ? a hot spot along the road
The increased travelling of today makes nodes along travelling routes more and more important. This is very much the case of petrol stations. They constitute important nodes in the road network, filling up thirsty fuel tanks and hungry stomachs, guiding road users and providing vehicle-services. In this thesis the role of the petrol station for road users was investigated in order to find out if the petrol station was a potential hot spot. We performed an ethnographic field study at a petrol station and found that a great number of visitor activities took place at the petrol station.
Bakhjulsupphängning, fyrhjuling
Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction.
Ett svenskt system i fjärde generationens krigföring
Stridsfordon 90 togs fram för att möta en reguljär motståndare på vårt eget territorium. Dagens krav och förutsättningar är annorlunda då striden främst genomförs i konfliktzoner utomlands, men även på vårt eget territorium. Motståndaren vi möter nyttjar andra metoder för att genomföra sin strid och agerar på ett annorlunda sätt än vad vi är övade vid.Syftet med arbetet är att undersöka hur ett förband med stridsfordon 90 lämpar sig i strid på dagens stridsfält mot en irreguljär motståndare. För att ta reda på detta så beskriver jag fjärde generationens krigföring och stridsfordon9040Cför att sedan kunna analysera och jämföra den taktiska nivån utifrån de grundläggande förmågorna.Användningen av strf 90 och mekskytteplutonens taktik mot en 4GW motståndare är lämpliga att användaapligt på den taktiska nivån. Mekskytteplutonens taktik är flexibel och sätter få begränsningar mot taktiken hos en anfallande 4GW motståndare..
