Reglering av en flödeskalibreringsrigg
Demag Delaval Industrial Turbomachinery (DDIT AB) i Finspång tillverkar gasturbiner.I dessa finns det ledskenor/skovlar som arbetar i så varma områden att de måste kylas för att få rätt livslängd. Vid nytillverkning och reparation mäts kylflödet genom respektive skovel/ledskena för att säkerställa att flödet och därmed kylningen ligger inom tillåtna gränser. Mätningen görs med hjälp av en flödesrigg.Denna rigg består av en ventil för inställning av luftflöde, utrustning för mätning och reglering av flödet och anslutning för den aktuella komponenten.Vid DDIT har en datorreglerad flödesrigg tagits fram för att användas vid kontroll av ledskenor/skovlar. Riggen fungerar, men tryckregleringen behövde förbättras.I detta arbete har reglerventilen och flödesriggen studerats för att kunna automatisera mätningarna. Olika reglermetoder har utvärderats.För regleringen används PID Control Tools från National Instrument?s LabVIEW®.
Utvärdering av anaerob behandling av hushållsspillvatten och tekniker för efterbehandling
The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.
Pedagogisk dokumentation i ett förändringsarbete
The main objective of this study was to find out what pedagogical documentation does and to get knowledge of what you may need to consider in order starting a process of change with a focus on pedagogical documentation. To get answers to my questions, the study is based on pedagogical theories from scientists and interviews with three preschool teachers who have different experience on documentation. My main questions were: What characterizes a pedagogical documentation? What tools / materials do I need to do a pedagogical documentation? What is important to consider when starting the process of change with pedagogical documentation? The result shows that pedagogical documentation is an approach that is based on that one is curious, interested, observant, listens, talking and researching with children and colleagues. You give the kids great participation which you can then pick up the children's learning processes and reveals that the business and the children develop according to curriculum objectives.
Utveckling av vippgunga för barn i åldrarna 1-3 år
Under våren år 2013 har Emilia Andersson, en designingenjörsstudent på Högskolan i Skövde, utfört ett produktutvecklingsprojekt i samarbete med HAGS Aneby AB. Syftet med projektet var att utveckla en vippgunga vars storlek skulle vara anpassad för barn i åldrarna 1-3 år. Målet var att vippgungan ska kunna säljas över hela världen samt uppfylla den amerikanska standarden och europastandarden för lekredskap.Projektet inleddes med en förstudie och teori-fas, där bland annat litteraturstudie och konkurrentanalys genomfördes och annan information samlades in för att få djupare kunskaper inom ämnet. Därefter började idéer och koncept genereras, som sedan genomgick utvärderingar, så som användartester, vilket ledde till ett slutkoncept. Konceptet utvärderades med hjälp av bland annat hållfasthetsberäkningar och en antropometrisk analys.Den slutgiltiga vippgungan kan trots anpassningen för åldersgruppen, inte bara användas av 1-3-åringar utan också av äldre barn, tack vare att konstruktion och framförallt handtag ger extra lekvärden.
Memes och kulturella artefakter
We chose to base our literature study on the meme phenomena. The meme is a portion of culture that is spread among us from mind to mind. Every time we learn something by copying others we use information that has been passed on from a previous person, that information can be seen as a meme. The theoretical frame for our methodology in our exam paper is founded on Forsberg och Wengström research on literature studies. Our aim is to describe to the reader in depth what a meme is and how they could be helpful in an academic and pedagogical setting.
Our study will show how memes are seen predominantly as graphic designs and as artifacts for cultural representation parallel to their imagery.
Datorn som komplement i undervisningen : En studie om datorer som ett led i läs- och skrivinlärningen
The school is a place of work where teachers, with different tools, are supposed to teach their students for the future. In the study the teachers? opinions will be lifted when it comes to use of computers as a tool to teach the students how to read and write. The interpretation is that the use of computers is reflecting the development of society and the intention is to find out if computers will be used in a didactic purpose in teaching. We focused on getting knowledge about which different opinions there are among teachers in grade 1-3 when it comes to the use of computers as a tool in teaching how to read and write.

Riskens förändring för svenska aktier och obligationer: 1919-2003
Purpose The purpose of our study was to investigate the changing nature of volatility during the last 80 years. Like in an American study, we tried to find some trends in the risk of stocks and bonds that would have an impact on the balance of a portfolio of stocks and bonds. At the same time we investigated the influence of inflation on the choice of portfolio. Methods We have used standard statistic tools and formulas to obtain our results. In most cases it was a matter of calculating average and standard deviation.
Styrtransmission för bandfordon
The purpose of this master thesis is to construct a steering transmission, for a trackedvehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

Konstruktion och prototypframtagning av pallväxlare
This thesis was conducted at AB Fredr Wagner in Ösmo in Nynäshamn, Sweden.AB Fredr Wagner provides solutions for the graphic industry and has been asked by acustomer to develop a product that can simplify handling of EUR-pallets, namely amechanical arrangement, further called pallet exchanger that can switch from anempty pallet to a fully loaded one using only hand force.The goal with the thesis was to create design documents for a pallet exchanger, andalso from those documents to manufacture a prototype for testing and evaluation.A field trip was made to the customer, IKAB mailing in Huddinge, where the palletexchanger is thought to be placed. The purpose of this field trip was to get an insightinto the current work condition and need of change, as well as to gather informationregarding the requirements when it comes to size and robustness of the palletexchanger. Existing equipment on the market that can perform similar tasks werestudied in order to find an optimal solution for the actual pallet exchanger.After the field trip and gathering of information the concept generating phase began.The method used for generating concepts was brainstorming. To decide on whichconcept to use, a concept selection matrix was created. The selection criteriaincluded in the matrix came from the requirements for the pallet exchanger.

Mätning av abrasivflöde för vattenskärningsmaskiner
The content of the following report is the summarized result of three students
thesis at Blekinge Institute of Technology in co-operation with Water Jet
Sweden AB.
This report will give the reader a description of principles how to measure the
abrasive mass flow in a waterjet cutting system.
The work began with a visit to Water Jet Sweden AB to get a closer look at the
problem. When the analysis of the problem was done the criteria were defined in
the form of demands and desires. The main task of the criteria was to guide the
search for the solution. The work proceeded with an extensive search for
abrasive flow meters along with obtaining information about flow measurement in
general. When the search for abrasive flow meters resulted in nothing all the
efforts were concentrated on finding a principle of measurement that could cope
with the criteria.
