Automatisering av flexibel fixtur
This thesis was conducted at Linköping University and SAAB Aerostructures, Linköping, and focuses on the automation of flexible fixturing in machining applications. At Linköping University a project called "Koofix" is conducted with support from Strategiska stiftelsen and several manufacturing industries including SAAB Aerostructures. The purpose of this project is to develop a more cost-effective, flexible, technique for fixation of workpieces during processing and assembly.Fixtures are an important part during the machining process, especially if you process the parts with high accuracy. Today a large number of fixtures are used at SAAB and they would prefer to reduce the number of fixtures by using flexible fixtures instead. SAAB uses one fixture for each article and this result in a high fixture cost and it also takes time to design and construct a new fixture.There are several advantages with using a flexible fixture such as that you can process workpieces with different length, height and thickness in the same fixture.
Lojalitetsprogrammet Eurobonus fall inom det svenska inrikesflyget
Den 30:e september 1998 mottog Konkurrensverket ett klagomål ifrån Braathens Sverige AB, enligt vilket SAS (Scandinavian Airline System) anklagades för att på olika samverkans förfarande missbrukat sin dominerande ställning på den svenska inrikesflygmarknaden. Några veckor efter klagomålet från Braathens beslutade Konkurrensverket att avsluta klagomålsärendet och istället på eget initiativ pröva SAS förfarande. Den 12:e november 1999 beslutade Konkurrensverket att SAS inte fick tillämpa sitt Eurobonussystem på inrikeslinjerna där det fanns andra konkurrenter. I praktiken rörde det sig om linjerna Stockholm-Göteborg, Stockholm-Malmö samt Stockholm Sundsvall..
Referenser i informationsåtervinning: utvärdering av en sökstrategi för citationsindex
In this essay, a search strategy for citation index is studied. The strategy, which is essentially a citation cycle, starts with documents retrieved by a subject search, wherefrom new documents are identified following the network of citations backwards and forwards in time. Based on the theory of polyrepresentation, the strategy exploits overlaps between cognitively different interpretations of the same documents in order to automatically select references seed documents used as a starting point for the forward chaining. The purpose of the investigation is to evaluate the retrieval effectiveness of the search strategy and to find out whether the strategy can be used to expand a subject search with the help of the network of references in order to retrieve new relevant documents. Two questions are formulated: 1a.
Brist på själslig insikt? : Utomjordingar och deras forskning kring människan i Dark City
The paper examines how human inner properties and the interpretation of the external worldare explained and presented in Dark City (Alex Proyas, 1998). Aspects as the relationship between the body and soul/consciousness, body snatching, memory transferences and dystopian cities are analyzed. The field of study is compared to a general science-fiction film perspective regarding the aspects. Dark City contains an alien race with a common mind, but who lacks soul and individuality. They represent what humanity can become if the scientific development goes too far.
Statusbedömning och förbättringsförslag för startkedjemaskineri, startkedja och linspel för stränggjutningsmaskin
The main goal with the master thesis has been to do a status evaluation of the chain machinery with its start chain and wire to secure the production on a short basis due to that a reconstruction is not planned at this time. An evaluation of the condition of the start chain and the rollers in the chain depository has been done. An offer has been requested for a new start chain and the evaluation of the start chains may be a basis for the decision taking. The production has been able to go on, although it has arisen some problems which have been difficult to find the causes for. There is no gathered ?picture? of the machinery status and a mapping of each machinery has been compiled of comprehensive logs.
Elektroniska signaturer- säker identifiering?
Problem:I dag finns det ett stort behov av säkra identifierings metoder på
Internet. Traditionellt sätt är en handskriven namnteckning en form av
identifiering och vad som behövs är en elektronisk motsvarighet.
Hypotes: "Elektroniska signaturer leder till ökad integritet och säkerhet vid
identifiering på Internet"
Syfte: Målet och syftet med denna uppsats är att studera och analysera huruvida
elektroniska signaturer kommer att bidra till ökad integritet och säkerhet vid
identifiering på Internet.
Slutsats:Genom att jämföra praktiska erfarenheter (fallstudie) och
teoretiska kriterier kunde vi analysera oss fram till att vår hypotes är sann.
Sara skolkar: Ett mobilt frånvarorapporteringssystem
This bachelor thesis portray a project where the main task were to develop a
computer based system prototype for handling of absence report at the upper
secondary school af Chapman in Karlskrona. The project has been conducted in
cooperation with students from the university programs software engineering and
information economy at Blekinge Institute of Technology. Our task as
MDA-students have been to survey the process of absence report of today through
field studies and give a proposal of a graphical user interface which later
were developed by the software engineers. The thesis also handles the
cooperation with other students from other university programs..
Är reducerad jordbearbetning ett alternativ? :
Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage.
In this paper we have tried to find out if reduced tillage is an alternative for farmers.
Vad krävs för att ett varumärke skall anses inarbetat?
Uppsasten vill ge svar på vilka förutsättningar som måste anses uppfyllda för att ett varumärke skall erhålla skydd genom inarbetning. Dessa förutsättningar har beskrivits med utgångspunkt i 2§ 3st VmL. Fokus i uppsatsen har även legat på marknadundersökningens roll vid fastställande av inarbetning. Där har en intervju genomförts med en representant från Stokholms handelskammares varumärkesnämnd. Varumärkesnämnden låter olika undersökningsföretag utföra diverse marknadsundersökningar.
Förbättring av Egenvärmehus : En fallstudie av ett flerbostadshus, Kv. Fyrtornet
Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

Skälby park is situated approximately 2,5 km
northwest of the central parts of Kalmar and is
one of fi ve town part parks. Originally Skälby
consisted of a village of four farms. In 1965
the municipality in Kalmar bought Skälby and
the agriculture ceased to appear. The land was
parcelled out into plots and new roads. Only
the area surrounding the old buildings remained,
turned to a park.
TV-spel och folkbibliotek - nya medier, mediepanik och biblioteksdiskurser
The aim of this master's thesis is to study what attitude public libraries in Sweden show towards video games. By using critical discourse analysis as both theory and method we analyse several texts emerging from a debate mainly discussed in blogs. Main topics in the debate are video games in the library, the purpose of the public library and Library 2.0. Our analysis focus on views expressed concerning the work and purpose of the public library, the librarian and the library user - and to identify the main visible discourses in the discussion.Our findings consist of two discourses representing two different views in the debate. We call these two discourses the general educational discourse and the interactive discourse.
