Gräfsnäs dolda skatter
This paper examines how to use different kinds of source material for building surveys. The studyexamines how to use legends, construction archaeological surveys and Ground Penetrating Radar(GPR) as source material, and use them against each other to ensure the reliability they have.As a starting point I used Gräfsnäs castle ruin in Alingsås, Sweden, as an example. Gräfsnäs castlewas probably built in the Middle Ages and was rebuilt through the ages until it became a ruin in thelate 1800s. The castle ruin is today Alingsås most visited attraction.The investigation has focused on three areas which are located in the very ruin; rescue tunnels, thecellar vault and the treasure.There are legends that describe how the castle lord of Gräfsnäs fled an attack of the Danes in 1612 ina rescue tunnel which ended at the beach. At the construction archaeological surveys carried out in1935-36 they found a sewer in the courtyard that was once served as rescue tunnel and ended in themoat.
Modus vivendi. : Om könsidentitetens motstånd och beständighet i kvinnodominerade yrken.
The aim for this study was to find out what strategies women use to not react against inequality and sexist prejudice. In the study I used a critical realistic approach through, primary, the social ontology presented by Margaret S. Archer. The study focus on both the women?s construction of femininity and their construction of masculinity and what directions it constitutes for the women?s social orientation.
Teknologistudenter och informationshantering en studie om informationskompetens vid Linköpings Tekniska högskola influerad av grounded theory
The main purpose of this study is to investigate and understand how technology students handle information especially when they are working with their Masters thesis. A further purpose is to examine how technology students use library resources of the Linköping University. The research method used is grounded theory, where description of the method is an integral part of the study. Twelve qualitative interviews were made with newly qualified graduates from the engineering programs of Linköping Institute of Technology. The respondents were divided into two groups, A and B, with six in each group.
Kostnadseffektiva, vackra fackverk av limträ
Syftet med examensarbetet var att skapa ett kostnadseffektivt, vackert fackverk av limträ i en samtidig utvecklingsprocess med arkitekt, konstruktör och entreprenör. Metodiken har till stor del följt idéerna i concurrent engineering, en samtidig utvecklingsprocess där alla involverade gemensamt kommer fram med förslag och lösningar. I och med att arkitekt, konstruktör och entreprenör jobbar samtidigt utformas också hela konceptet inklusive detaljer och produktionsprocess i en och samma utvecklingsprocess. Till stöd för beslutsfattandet i designprocessen har axiomatisk design använts, vilket är en metodik som hanterar design i matematiska termer. De olika lösningar som evolverar från processen concurrent engineering har sedan optimerats med ett Matlab-program med avseende på lägsta materialkostnad.
Ett verktyg för konstruktion av ontologier från text
With the growth of information stored over Internet, especially in the biological field, and with discoveries being made daily in this domain, scientists are faced with an overwhelming amount of articles. Reading all published articles is a tedious and time-consuming process. Therefore a way to summarise the information in the articles is needed. A solution is the derivation of an ontology representing the knowledge enclosed in the set of articles and allowing to browse through them. In this thesis we present the tool Ontolo, which allows to build an initial ontology of a domain by inserting a set of articles related to that domain in the system.

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.
Lean inom sjukvåren : Effektivisering av patientflöde
This report describes the planning and the accomplishment of the final diploma workat the study program Mechanical Engineering, Department of Engineering Sciences, Uppsala University. Two students carried out the diploma work at GE HealthcareHusbyborg in Uppsala.The aim of the diploma work was to develop and improve existing processequipment for 11C-radiochemistry in PET. The process equipment was to be dividedinto smaller independent modules to make it more flexible. Part of the existingprocess equipment is an oven that is supposed to perform a specific chemicalreaction. One of the main goals was to study and improve this oven.The work could be divided into three main phases: 1.Present concepts for one module, and interface between different modules.
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.
Brandskyddsindex Visby innerstad
The aim for the project was to develop a risk analyse tool for measuring the fire safety level in Cultural Heritage buildings of Visby, Gotland. In 1995 Visby were taken into the Unesco:s World Heritage List with the explanation ?Visby is an outstanding example of a Northern European walled Hanseatic town which has in a unique way preserved its townscape and its extremely valuable buildings? One of the demands for the tool was that it should be easy to use and result into a ranking level in examined buildings. The user of the tool is recommended to be personnel in the fire department. To develop the tool a Multi Attribute Decision Making (MADM) method was used.

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.
