Utvecklingsmodell för hydrauliska svivlar
Indexator Rototilt Systems erbjuder tiltrotatorer och systemlösningar för anläggningsmaskiner till sina kunder. Tiltrotatorerna kan oftast ses på grävmaskiner. Dessa är placerade mellan grävmaskinens grävarm och skopa. I tiltrotatorn sitter det en viktig komponent, kallad svivel. Sviveln gör att tiltrotatorn kan roteras obehindrat runt den egna axeln samtidigt som en kontinuerligt hydraulisk förbindelse upprättahålls mellan redskapet och hydraulsystemet.
Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management
AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.
Kommunikation med hjälp av mock-uper
In several cases, systems that have been developed have been very time
consuming and cost a lot of money, but they still do not fulfil the users
requirements and requests. To make new systems better, you have to find a way
to communicate that allows the developers to understand the needs of the user.
The aim for our thesis is to highlight the importance of communication in
system development. To investigate this we have choosen to do a study of the
real-estate system. The work methods that have been used include mock-ups and
informal conversations with the user, who is employed by the Church of Sweden
in Ronneby.
Projektering av fårstall :
The purpose of this work was to see if it was possible to rebuild an old dairy house into a house fore sheep production. The goals fore the work was to see witch kind of production model was suitable, how the actual drawing would look like and witch kind of interior was needed.
The building was built in the beginning of 1900. It is located on the mountain Kinnekulle in Sweden. It was a big production fore its time and hade about 60 dairy cows. It was a lot of hard work because the floor was built by big stone blocks and it was very hard to rebuild when some more automatic solutions came fore handling all the manure.
The idea of remaking the building came when we rebuilt the roof fore 5 years ago.
Läsflyt : En interventionsstudie på två läsmetoders effekter på läsförmågan.
Sammanfattning Syfte: Att undersöka två läsmetoders effekter på tolv elever från skolår 2, 3 och 4 avseende fonologisk och ortografisk läsförmåga, läsflyt, läsförståelse och RAN (Rapid Automatic Naming) samt jämföra resultaten med en grupp elever som fått traditionell specialundervisning under samma tid. Metod: 52 elever genomförde en screening med avseende att mäta läsflyt och läsförståelse. Av dessa valdes 12 elever ut som hade svårigheter i läsflyt och korrekt läsning, fyra elever från varje skolår, 5 pojkar och 7 flickor. Eleverna delades i två lika stora grupper som tränade ordavkodning med två olika metoder i en-en-undervisning, 20 minuter tre gånger per vecka i sex veckor. De 18 eleverna fick utföra ytterligare fem läs- och skrivtest före och efter interventionen. Resultat: De båda interventionsgrupperna förbättrade sina resultat på flera test mer än gruppen som fick traditionell specialundervisning. Elever som tränat Rydaholmsmetoden fick bättre resultat i alla högläsningstest utom ett.
Källsorterade systems påverkan på avloppsreningsverk : växthusgaser, energi- och resursanvändning i modellstudie
The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

Jämförelse av resultat mellan manuell gelkortsanalys och automatisk immunohematologisk gelkortsanalys vid utförande av blodgruppskontroll och antikroppsscreening (BAS-test)
Incompatibility between donors and recipients can cause fatal hemolytic transfusion reactions (HTR), kidney damage and death and immunization of the recipient. Antigens on the surface of erythrocytes in the ABO blood group system and regular natural antibodies against these in the patient?s plasma must be considered. An individual always has a corresponding antibody of IgM in their plasma. Irregular antibodies acquired by transfusion or pregnancy and active in body temperature also cause the HTR incompatibility.
En union, ett samarbete och en valuta i kris : En kvantitativ studie om Spaniens och Sveriges mediala framställning av euro- krisen inom EU
AbstractTitle: A union, a collaboration and a currency crisis- a quantitative study of the media coverage of the euro crisis within the European Union in Spanish and Swedish newspapers.The purpose of this study was to see whether Sweden and Spain ?s differences in media climates and relations to the euro crisis would affect how the story was portrayed from a narrative perspective. Did the coverage differ between the two countries and who got to comment on the situation in the media were two of the questions I strived to answer. I also wanted to see how the coverage reflected on the situation that the euro crisis has created.In this study I used a number of theories that I based my research on. The main theories I focused on was about different media systems and Sweden and Spain ?s relation to the euro crisis.
Fallstudie av produktionschefers ledarskap
The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.
Etableringsstrategier för spannmål : en studie av investeringsbeslut i maskinsystem
In order to produce grain in an economically rational manner numerous decisions have to be made. One of these decisions is what tillage system to use. The cost of the tillage system is a large part of the total cost in grain production. Different tillage systems result in different distribution of fixed costs, operating costs and timeliness costs. The price of the produced grain and cost of inputs also affect the best way to produce grain.
Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie
This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.
Projektering av passersystem : En studie i användarstöd vid offertarbete för ARX passersystem
To have a tool that guides you when you work with a complex system can be helpful since the complexity of the work can be reduced. In this thesis I explore the possibilities to use a helper application whilst planning installations of access control systems. The purpose of the application is to provide support during the planning and at the same time make the user aware of the limitations that exist in the access control system ARX Access. By combining early user input and the theory of formativity, the result became an application written in Java..
Bidrag till metodutveckling för webservicedesign, baserat på en verklig fallstudie
Web services are now a day often mentioned when speaking of systems communicating with each other online. This master thesis describes how we, with a grounded theory, developed a web service from scratch and then used it to describe how to develop a method for this case scenario. The purpose of the web service is to simplify the information exchange between Infra Gaming, which is the company who assigned this project to us, and their customers. This master thesis is not a guide to how you develop a web service. It is a master thesis that describes how we, in three steps, solved the assignment from Infra Gaming and our problem, with a web service..
