Optimering av betong med Byggcement (CEM II) till håldäcksproduktion
This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..
Bibliotekariestudenter och söksträngsexpansion: Ett experiment om manuell söksträngsexpansion
The focus of the thesis is an information search technique called manual query expansion, which aims to improve the retrieval per-formance in a search system by adding terms to the search query. The study looks at the query expansions done by LIS students, and the eventual beneficial effects by using a search help during the search process. The empirical data have been collected thro-ugh an experiment, with an experiment group as well as a control group. The conclusion is that the students need more education in query expansion in order to be able to use it correctly. There are significant differences between the groups in several aspects, for example in the use of search terms, parentheses, and truncation.
Film om film : En analys av dokumentärfilmer om fiktionsfilmer
This thesis is a study of documentaries about fictional feature films. The development of the DVD format has contributed strongly to their massive increase in quantity. The capacity of the format enables film companies to include more material than the feature film itself. As some people regard this type of documentary as self-righteous and presumtious, others think of it as a great educational aid giving the audience a greater understanding of the intentions of the director and others involved, thus adding more levels to the experience of watching movies. By using established theory on documentary I?m trying to find distinctive features of ?documentary on fiction?..
Internal Quality Audits as an Improvement Tool
A large proportion of businesses around the world is today ISO 9001 certified and is consequently conducting internal audits on a regular basis. It has however not been possible to conclude that internal audits always add value to the organisation, despite the large utilisation of this tool. Some authors, e.g. Alic & Rusjan (2010) and Wealleans (2000), mean that there are possibilities that internal audits may be used as a value-adding improvement tool. This has led to the emergence of this master?s thesis.The purpose of the case study was therefore formulated to examine how internal quality audits can be made more effective and used as an improvement tool.
Formgivning av möbler i SWISSPEARL Carat
This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.
Ombyggnad av takkonstruktionen på Östermalms Saluhall : Utformning av tilläggsisolering med hänsyn till byggnadens kulturhistoriska värden
Vid ombyggnad av Östermalms Saluhall är ett förslag att tilläggsisolera taket, då ställs det kulturhistoriska värdet av byggnaden mot ombyggnadskraven i BBR. Idag gäller samma krav vid nybyggnad som vid ombyggnad av en byggnad. Det kan därför uppstå tvister vid ombyggnaden av saluhallen, då det är svårt att samtidigt uppfylla nybyggnads- och ombyggnadskrav på de delar som ska ändras.De delar på saluhallen som studerats är två takdetaljer och de projekteras och analyseras byggtekniskt, kulturvärdesmässigt och lagmässigt. Det kulturhistoriska värdet hotas vid ombyggnation, men samtidigt vill Stockholms stad energieffektivisera byggnaden så gott det går. Studien handlar därför om hur man på bästa sätt ska kunna energieffektivisera byggnaden och följa de ombyggnationskrav som finns utan att förvanska byggnaden..
Materialspill i byggnadsproduktionen : Waste of Material in the Construction Industry
This report deals with issues related to construction waste. Building material that has not been built into the project is defined as construction waste. Cost of construction waste amounts to 4-12 % of the total cost of the project. Moreover, cost of construction waste is 1-3 % of the production cost. The aim of this study is to increase knowledge about the main causes of waste within the construction industry.
Ytterväggar : En jämförelse och livscykelskostnadsanalys
This report discusses the constructionof different types of exterior wallconstructions and analyses wall layers.Standard wall constructions from theSwedish building contractors NCC andSkanska and also from the materialproducer Isover have been chosen for theresearch. Life cycle cost analysis hasbeen made to conclude the mostprofitable wall type, seen from asustainable and economic perspective.The calculations have been made for aperiod of 50 years.The report shows that building with wellinsulated walls is a more profitablesolution both economically and whatconcerns sustainability even though thehigher investment. However, when wallssimilar insulation properties are beingcompared, the study proves that lowerinvestment cost is more profitable.The report introduces requiredconstruction techniques of walls inorder that the reader should understandwall constructions with different layersand properties. The essay shows theimportance of properly constructed wallsto avoid air leakage and moisturedamage.The essay has been implemented byliterature studies, contacts with NCCand Skanska and by energy calculationsmade by hand and using the software VIPEnergy..
Musik och indexering i folkbiblioteken
This paper follows an analytical and critical line of reasoning concerningindexing and retrieval of music in Swedish public libraries. The focus ofthe discussion is based on the terms included in the subject heading list ofthe Swedish Classification System. The empirical study is performed inthe context of online catalogues in the public libraries of Örebro andGävle. The theoretical background relies on the indexing theory ofProfessor Frederick W. Lancaster.
Påbyggnad av våningsplan medlättkonstruktion : En jämförelse av stommaterialen trä ochtunnplåt
The purpose of this thesis is to examinethe possibilities for adding a floor to anexisting building using the two materialswood and sheet metal profiles as the loadbearing structure. An apartment buildingfrom the 60s has been used as referencehouse. Two different suggestions for thedesign are presented in the rapport. Oneof them has been analyzed with wood andsheet metal as the load bearing structure.Using the old constructional calculationsand blueprints of the existing buildings,the load bearing capacity has beencalculated. In the calculation programFEM-Design the building has been testedwith the loads that an extra floor wouldgive.
De osynliga stränderna - en omvandling och undersökning av boken De osynliga städerna
My project is an interpretation and exploration of the book The Invisible Cities by Italo Calvino. It is a play on the swedish words for cities and beaches. By adding the letters R and N the word for cities in the title transforms into the word for beaches. The project is equal parts a color investigation and an exploration of new working methods as it is an development of my approch to graphic design. My aim was to, through a visual, conceptual and playful investigation create a new interpretation of the book The Invisible Cities.

Kreativ produktexponering inom e-handeln
This study investigates whether creative online product exposure within the clothing industry has a positive effect on the behaviour and attitude of today's consumers. Product exposure is the most important stimulus in the online marketing universe, yet few studies exist on this topic. Thus, this study pioneers in this specific research field. Through empirical analysis this study reveals that product exposure has a significant and direct effect on the perceived corporate ability and consumer involvement. Moreover creative product exposure indirectly increases the perceived product quality, intention to buy and the overall attitude towards the brand.
CMS och UX : tekniker för hur man utformar en god användarupplevelse
The purpouse of this study is to find out how and if a Content Managment System (CMS) can benefit from applied User Experience Design (UX). A work project has been executed where a client wanted the students to create a user friendly CMS for adding content to a global hotel review site. A prototype of a CMS was created based on literature studies about UX and CMS. The prototype of the user friendly CMS was then tested through user tests and interviews with key users. After input from the key users the prototype was changed until the users were satisfied with it..
Klasser som påverkar : Om klasskillnader och förändring i politiskt deltagande under perioden 1968 - 20000
The purpose of this thesis is to see how small differences in a store can affect the customer behavior. The changes consist of auditory and visual sensory cues. Since many companies today makes a lot of changes in their styling element, but without knowing how it really affects the customer behavior we thought it would be interesting to see by doing an experiment at IKEA. The study is therefore based on a quantitative research method, where theories have been described and from which hypotheses have been derived to test the theories. The experience took place at IKEA during two weeks where 5732 observations were made.The result from the experiment is that the sensory cue sight makes individuals spend more time in the environment but not creating attention.
