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..
Studentboende - Helsingborgs nya studenthem
Vi har i vårt examensarbete undersökt Helsingborgs studentsituation på uppdrag av Helsingborgs Kommun. Redan nu är det bostadsbrist för Helsingborgs studenter och värre blir det i och med att studenterna förväntas nästan fördubblas dubbelt de närmaste fem åren. Därför behöver Helsingborg ett nytt studenthem omgående. Syftet med denna rapport har varit att utreda studenternas boendesituation i Helsingborg, för att sedan kunna presentera den bästa eller lämpligaste lösningen för ett nytt studenthem. Tanken är att denna rapport ska kunna ge Helsingborgs Kommun underlag för en eventuell nyproduktion.
Statushantering i Virtual Map med ledningssamordning i BIM
For many years, the construction industry in Sweden has not developed much of an integral approach for design across disciplines. The sector?s impact on society, economics and environment is huge. To make the interactions within the construction industry more efficient, a relatively new concept called BIM (Building Information Modeling) has been introduced. The idea with BIM is that the different actors of the construction industry will work through intelligent CAD software, with common file formats and more cooperation between different actors during the various steps of the building and construction process.The technical consultancy company WSP Sweden is working actively to implement BIM within the frame of its activities.
Hur fungerar Lean construction? : En fallstudie av NCC
Det har blivit allt dyrare att bygga i Sverige, den svenska byggnadsindustrin har halkat efter övrig producerande industri och byggföretagen måste börja tänka i nya banor om de ska klara de nya utmaningarna. Lean-tänkande har länge nyttjats inom den tillverkande industrin och byggföretag har på senare år börjat snegla på dessa koncept i syfte att öka sin produktivitet. Problemet är att byggindustrin inte har homogena produktionsmiljöer och därmed inte kan använda samma lean-koncept som exempelvis bilindustrin. Därför har ett nytt koncept som kallas Lean construction utvecklats som bygger på ett antal principer från traditionella produktionssynsätt (Koskela, 2000). Konceptet är relativt nytt och forskningen inom området har främst fokuserat på lösningar på specifika problem istället för att skapa förståelse för konceptets helhet.
Materialvagnstransport
A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.
En conjoint analys av förpackningsattribut.
Abstract
Title: A conjoint analysis of packaging attributes. How can the attributes of a
product?s packaging best look like to attract the consumer?
Authors: Linda Granberg & Helena Niklasson
Supervisor: Jan Svanberg
Department: School of Management, Blekinge Institute of Technology
Course: Bachelor?s thesis in Business Administration, 15 credits
Purpose: The purpose is to find out how visual and technical attributes on
product packaging affects the consumers tendency to want to buy the product.
Method: Conjoint analysis and a quantitative survey.
Results: When developing a package for a food product we?ve reached the
conclusion that it is most important to have clear product information on it.
The consumer wants it to be simple and easy to use, the people under time
pressure seeks product with new technology which can save them time..
Mänskligare prylar pratar. En kommunikationsplattform för äldre
Safety, its a word not commonly associated with elderly people living alone. There is however a device that is supposed to bring safety, and enable elderly people to continue living in their present household - an emergency dialer. However these devices does not serve their own purpose in terms of design. Thepurpose of this study is to create an emergency dailer that everybody would want to put on their wrist or bedside table. The market for these devices have looked the same for the last twentyfive years, despite of society´s advancements in both design and technology.
Fuktskador i bostadskök : En undersökning om fuktskador i kök och hur dessa kan förebyggas vid nyproduktion
Moisture damage in kitchens is an area that many people believe to be irrelevant andnot a subject to concern, however the problems encountered might be larger thananticipated.The purpose of this essay is to get a view of how problematic moisture damagecurrently is as well as what can be done to prevent damage during the constructionand building of new housing.Statistics regarding moisture damage as well as several tools for damage preventionhave been studied and investigated. Industrial regulations have been reviewed tounderstand the requirements construction companies must legally follow during theconstruction and building of new kitchens. Home manufacturers and largerentrepreneurs have been contacted in order to get their point of view regarding theproblems with moisture damages in kitchens.The knowledge of moisture safe constructions is prevalent by home manufacturers,insurance companies and entrepreneurs. Despite this knowledge, the constructioncompanies predominately follow the industries regulations, which normally onlyimplement the minimum requirements.In order to get construction companies to design and build kitchens with increasedmoisture security, stricter industrial regulations might be needed to be implemented.Unlike bathrooms and laundry rooms, kitchens are not defined as a ?wet room? andthe regulations for the construction of kitchens are more lenient.It is difficult to detect water leaks in an early state and the moisture damage is usuallyextensive before it is discovered and repaired if the kitchen lacks moisture securedconstruction and water security.
En ökad kontroll av tillverkningsresurser i samband med CAM-
beredning
Sandvik AB grundades 1862 av Göran Magnus Göransson som var den första i världen som lyckades framställa stål enligt Bessemermetoden. Idag, nästan 150 år senare, har Sandvik AB 44 000 anställda och är verksamma i 130 olika länder världen över och har en omsättning på närmare 72 miljarder SEK. (Sandvik) Sandvik är indelat i tre olika affärsområden: Sandvik Tooling, Sandvik Materials Technology och Sandvik Mining and Construction, vilket också är det område detta examensarbete berör. En del av produktionsberedningen av produkterna, CAM-beredningen, är att skapa de verktyg som produkten i fråga skall bearbetas med. Verktygen hämtas i dag från olika platser (databaser, mallar) och används sedan i beredningen för att simulera bearbetningen av produkten.

Nyhetsgrafikens utveckling
This bachelor thesis examines and discusses the question: "How can graphics for
newscasts be adapted to follow technological developments in various media and
increase its informative quality?"
The work was performed on Swedish Television's own graphic department, SVT
design in order to examine how news graphics need to be developed to follow the
technological changes in media.
The production resulted in a news graphics concept divided into three parts.
Two of the sections show examples of how graphics can be adapted according to
platform and the third section shows examples of news graphics that are
produced at SVT Design by me. The bachelor thesis focuses on the development of
technology in the media and examines areas such as interactive solutions, news
graphics and the traditional television media..
Cleanbox - Flashbaserad Produktpresentation
Cleanboxen som den kallas är en flashbaserad2 produktpresentation.
Simply Quality är ett företag som gör analyser och mäter renhet hos olika
föremål på partikelnivå.
Ett exempel på detta kan vara att ett företag som tillverkar bildelar skickar
en del efter produktion för att få en analys på hur mycket partiklar/smuts som
sitter kvar efter tillverkning.
Vårt arbete var att ta fram en produktpresentation för deras mobila labb som
säljs till företag som vill kunna göra sina analyser på plats. Behovet var att
på något sätt kunna presentera Cleanboxen visuellt för sina kunder..
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
