Metodutveckling för planering och genomförande av dikesrensning med moderna metoder
?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes.
In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests.
So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland.
We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning.
A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests.
This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.
Hinder för fysisk aktivtet hos ungdomar i övre tonåren
AbstractEmilia Rönnberg.Barriers to physical activity in adolescents in their late teens. Vetenskaplig C- uppsats HT 12 Physical activity has been essential to human health and well-being since several thousand years. In Sweden, it has been shown that both adults and young people are less physically active than the rest of Europe- a large proportion of young people today do not meet the recommendations for physical activity (60 minutes per day). The purpose of this study was to determine what proportion of young people, i.e. high school students, did not meet the recommendations for physical activity.
Samband mellan lågt tryck i dricksvattenledningar och magbesvär - En utredning av hur lågt tryck på dricksvattenledningsnätet vid lagning av läckor påverkar sjukligheten hos Göteborg Vattens abonnenter.
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
Ett plus ett blir två : Introduktion av likhetstecknet i förskoleklass och årskurs 1
Today there is a shortage of skilled IT-technicians in Sweden. It is approximated that Swedish companies can hire 31 000 IT-technicians in 2015 and the need seems to increase in the coming years. One proposed solution to this problem is to make programming more desirable to youths. In this study we attempt to investigate the effects of an introductory course in computer science on youths? (16-17 years old) in a classroom setting.

En undersökning och utvärdering av ledningssystem : Ett delprojekt i ett förändringsarbete
In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.
Modell för fördelning av kostnader i lager
Distrilux International AB, a company within the Electrolux-group, works among other things with storing of products from other companies in the Electrolux-group. This rapport contains a cost analysis of the two Distrilux warehouses in Motala and Mariestad. The company offers five services in these warehouses, in-loading of products from a local factory and from external factories, storing, out-loading of products to Sweden (domestic) and for export. Since there has been some hesitation of the accuracy of the price-model of today, a master's thesis has been advertised. The purpose of the thesis has been to investigate the agreement of the price-model of today and the apportionment of the costing in warehouses.The main problem is to determine which activities is to be considered important in the price-model.

Intern marknadsföring, hur påverkar den samarbetet med kunderna : En fallstudie på Flow Systems AB
This essay is a case study carried out at Flow Systems Ltd that foremost aims to treat the internal marketing at the company. The aim with the essay is to analyze and evaluate Flows internal marketing in connection with a process of change and how this reflects the external marketing in relation to customers.The method that has been used is qualitative in the form of depth interviews carried out with management, employees and customers. This type of data was chosen since it is a good way of gathering more specific information regarding the informants preferences about the company. Among other things the results of the interviews showed internal marketing deficiencies, but that has not influenced the customers in a negative way. The conclusion was that the inferior internal marketing does not affect the cooperation and the communication between the company and its customers, however it has a big effect on the employees..
Karaktäristiska gestaltningar av brukare och domän : ett systemperspektiv
För att skapa en produkt som stödjer kundens mål och arbetsprocesser är det av stor vikt att identifiera vilka, men även var och i vilket sammanhang de potentiella brukarna är och agerar. Moderna styrsystem ger möjligheter för flera olika personalkategorier att arbeta med systemen och dessutom används systemen inom skilda domäner där det finns olika behov. Det fanns därför ett behov att, på uppdrag av ABB, utreda vilka behov dessa olika personalkategorier har och hur styrsystemet uppfyller dessa, samt på vilka punkter systemet skulle kunna utöka sitt stöd för de uppgifter som skall utföras. I form av en fallstudie genomfördes därefter en kartläggning av arbetsmiljö, personalkategorier och olika uppgifter och mål som uppfylls av personalen. Fallstudien genomfördes utifrån ett systemperspektiv med ett sammansatt kognitivt system (JCS) som enhet för analys. Detta perspektiv var även tongivande vid presentation av resultaten i form av karaktäristiska gestaltningar av både brukare och domän. Studien har visat att befintliga gestaltningstekniker inte är tillräckliga för att gestalta brukare, domän och samspelet där emellan.
Framtidens driftcentral : En analys av den framtida driften av ett svenskt elna?t
Active work to increase the efficiency of energy use is taking place in Sweden and throughout all of Europe. Electricity is an important part in our society?s energy system which means that the electrical grid operators and associated therewith has a central role in this work. Monitoring and controlling the electrical grids are managed from the distribution system operator?s DC, dispatch center.The aim of this report is to examine how the operations in a typical DC on the Swedish electricity distribution network will look like in five to ten years.
Värme & El med Stirlingmotor
En billig och robust motor av stirlingtyp har konstruerats för användning i
villor. Som energikälla används de heta rökgaserna från förbränningen i husets
panna. Motorn driver en generator i permanent drift under den kalla delen av
året då värme- och energiförbrukningen är som störst i vårt land. Under den
varma årstiden finns den tillgänglig som reservkraftverk.
Tanken är att stirlingmotorns värmare ska placeras i en villapanna för att ta
till vara exergipotentialen hos dess höga temperatur.

Use of computers and computer networks is nowadays a part of everyday life. You do not use them only at home when you sit at you computer, but you can use them all the time everywhere. This can involve everything from surf to any website when you are at home, to checking your email on your mobile when you are on your way to work. Most people do not think about how it really works when they try to access a web page by typing the address into their browser, but something that most people probably notice is how long it can sometimes take to access a web page.All items which are directly connected to the IP network have a unique IP address that is used to make it possible to communicate. The IP address is either a period separated sequence of digits representing 32 bits or a colon separated sequence of digits representing 128 bits, depending on whether the address is an IPv4 or IPv6 address.
Personlighetsskillnader mellan gymnasielärare och blivande gymnasielärare : Differences in personality between high school teachers and future high school teachers
The climate issue is a significant question, and the problem is mainly caused by human activities. Everyone can help to counteract the enhanced Greenhouse effect by reducing the amounts of energy they use and by not consuming more products then they need.Schools are some of societies many consumers and therefore contribute to the Greenhouse effect. The School also has an important task; to teach and disseminate knowledge and information about the climate and the environment. According to the Swedish National Agency for Education, Skolverket, must all schools regularly consider the environment and sustainable development throughout the entire education process. Unfortunately, this is not the case for many schools in Sweden today.One of many tools that can be used to coordinate environmental work and initiatives, and also to make it more efficient, is environmental management systems.
Ström- och temperaturkontroll
Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.
