Radomoptimering för luftburna störsändarkapslar
These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..
Modell för dimensionering av AGV-system inom tung industri
Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.
Analysis of CD4+ and CD8+ T-lymphocytes : A comparison between EPICS XL and Celldyn Sapphire
Flowcytometric technology has been widely used for measurement of the absolute numbers of T-lymphocytes subsets in Human Immunodeficiency virus (HIV), defining the disease state, monitoring antiviral treatment, and identifying any risk for opportunistic infections. A manual preparing of the samples is required. More recently an automated and enclosed blood cell counting, Celldyn Sapphire has been introduced. In this study the performance of the Flow cytometer EPICS XL as a reference method for analysis of CD3+, CD4+ and CD8 T-lymphocytes was evaluated with blood from 40 individual?s samples.
Automatisk lockmekanism : från idé till prototyp
Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.
Kultur - vad ska det vara bra för? : En studie av organisationskulturen på ett centrallager
Syftet med denna uppsats är att undersöka lagermedarbetares upplevelser och behov av organisationskultur på en specifik arbetsplats. Syftet är även att undersöka chefernas syn på organisationskultur och hur organisationskulturen kan användas som ett verktyg för att främja motivation och trivsel bland de anställda. För att uppfylla detta syfte använder vi oss av följande frågeställningar:- Vilka organisationskulturella aspekter kan vi identifiera i företaget?- Hur påverkar dessa aspekter lagermedarbetarnas motivation och trivsel på arbetsplatsen?Vi använder en kvalitativ undersökningsmetod för insamling av empirisk data. Med hjälp av sociologiska och socialpsykologiska teorier besvarar vi frågeställningarna utifrån sju intervjuer med chefer och lagermedarbetare på ett centrallager i Mellansverige.Resultatet visar att ledningens arbete med de organisationskulturella aspekterna vi identifierat visar likheter med de teorier där organisationskulturen är en del av en ledningsstrategi.

OLAP har blivit mycket populärt och det finns idag många verktyg ute på marknaden ? vi valde i vår undersökning att utvärdera några av dessa verktyg. Syftet med denna studie var att visa på de eventuella brister OLAP-verktyg idag dras med ur användbarhetssynpunkt men samtidigt lyfta fram de positiva aspekter de medför.
Preflight utvärdering
PDF-files are to become a native file format in all prepress supplier workflows during 2006. This will give an opportunity to automate and develop a more stream lined prepress workflow. It is desirable to secure digital files by preflight the files early in the process. The objective with this project is therefore to find software that can automate parts of the preflight process and also to build up a well-functioning preflight workflow for preflighting both PDF-files and native files.Meetings have been held with preflight suppliers to find a solution for how to automate parts of the preflight in the prepress workflow. Seven preflight software companies demonstrated the possibilities with their products and four of these were chosen for continuing working with.
Styrkan i OEE som arbetsmetod
The E-department at GETRAG All Wheel Drive in Köping have problems with the efficiency on parts of their production equipment. The equipment with the most significant efficiency problems are four automated multifunctional production cells that produces housing for rear drive units. The major part of the problem is the large amount of small stops that causes the low efficiency.The department already worked with logging of interruptions and efficiency calculations before this project started. However this work was not done to the extent considered necessary for a systematic follow-up of the interruptions.The aim of this paper is to point out a more effective and systematic way to work with logging of interruptions and the follow-up. In addition the equipment were studied with a method for efficiency calculation that ? if used properly- is a more powerful and a visually better method than the one used by the company today.As the initial current state analysis of the equipment was made a lack of documented knowledge about the equipment was discovered.
Konstmuseum och torg i Uppsala
Uppsalas nya konstmuseum har fått sina proportioner från det som redan innan fanns på platsen. Godsmagasinet, en låg avlång tegelbyggnad från 1908, har gett det nya museet dess form. Magasinet och museet sträcker ut sig längs varandra. Mellan dem byggs ett nytt torg på vad som tidigare var en parkeringsplats. I båda ändarna av byggnaderna leder trappor upp till torget som är upphöjt en bit ovanför trotoaren, i samma höjd som godsmagasinets gamla lastkaj. Idag inrymmer magasinet ett kafé, två butiker och en jazzklubb.

Zetterberg's Industri AB believe that capital and lead time will be reduced by implementing Kanban. Therefore, it was an investigation to prove that Kanban is an effective method. In this work a research had to be done to show how the material supply system looks like today and to explore the subframe components to see which components that are interesting from Kanban viewpoint. Previous orders of subframes were investigated. Therefore, it was a list of the various components of the previous orders for the subframe.
En analys av TPL-företag och deras samarbete med kunder
AbstractThe purpose of this paper is to analyze TPL companies, and their collaboration with their customers from a TPL perspective. The paper intends to get a bigger understanding of their collaboration, advantages/disadvantages and how the collaboration can be improved. The foundation for the paper is obtained through questions that have been created from the chosen theories about supply chain, third part logistic (TPL) and lean production. We have had open interviews with five different conveyers where we have had our questions prepared and during the interviews asked new questions to get more distinct answers. When we subsequently analyzed the empirical material and by chosen theories we have been able to confirm that the collaboration between the TPL companies and their customers is more of a partnership character.

All seven principals answered the questionnaire and five of them agreed to participate in an interview. Another two interviews were made with two informants, this material was included in the background material. As theoretical framework I have used literature about the school library development, the role of the principal for development and David V.
Användarvänlig design av bibliotekskataloger på webben.
The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.
