Rapporten behandlar och utvärderar tre olika isolermaterial, Polyisocyanurat (PIR), grafitcellplast och mineralull, vid tilläggsisolering av miljonprogrammets byggnationer.  Stora delar av miljonprogrammet är nu i behov av upprustning. Samhällets skärpta krav gällande energiförbrukning gör att nya rationella metoder och material krävs för att tillgodose ställda krav. Att tilläggsisolera är en del i denna upprustning, och eftersom valet av isolermaterial ofta faller på gamla beprövade metoder och materialval, såsom mineralull, syftar denna rapport till att öka kunskapen om alternativa, mer högpresterande isolermaterial.Isolermaterialens egenskaper tas först upp och behandlas i en generell jämförelse där ekonomiska och tekniska aspekter beaktas.För att konkretisera och påvisa utfallet i ett specifikt fall genomförs en studie för ett referensprojekt, kvarteret Hundlokan, som ägs och förvaltas av Fastighets AB Förvaltaren. I studien undersöks tre olika alternativ för vart och ett av materialen vid tilläggsisolering utvändigt av Hundlokans fasader. Samtliga alternativ ställs sedan mot varandra och utvärderas med hjälp av: fukt-, U-värdes-, energi-, kostnads- och LCC-beräkningar (livscykelkostnad).Enklare fuktberäkningar som påvisar relativ fuktighet (RF), ånghalt och temperatur i väggens olika skikt genomförs.

During the last decennium climate issues have become more and more important. Many steps towards an adaption of efficient energy supply systems have been taken all around the world. These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.

This thesis aims to identify bottlenecks in the internal communication of aSwedish public library. Specifically, it addresses the behaviour of the library staff when they seekfor work-oriented information through interaction with their colleagues. A fundamental assumptionof this study is that the information-seeking process depends on organisational culture. I have madean exploratory case study in a medium-sized Swedish public library, where relevant issues areidentified and correlated with the culture of the organisation.I have used Schein's three-level model to describe the culture of the library; this model definesculture as a set of basic assumptions and the actions of people as expressions of their culture. Datafor the study were gathered using several approaches, including interviews with the library staff andobservations of them.

The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.

This study explores the effects of two different post-treatment methods on stain reduction in glazed creamware from the late 20th century. The objects stains have been characterized by type one and type two stains which is the result of prolonged contact with food residues, were subjected to the same initial stain reduction. The two post-treatment methods examined are soaking the objects in deionized water and surface rinsing with deionized water. The comparative analysis included photographs under normal and UV-light exposure to assess stain visibility, weight measurements before and after treatments to monitor the absorption and evaporation of liquids, and observations throughout the experiment. The results revealed that while type two stains showed significant alterations after treatments, specifically after soaking, type one stains remained unaffected by both methods.

In today's Sweden there are approximately 23 000 combination companies, and most of them have a connection with the agricultural sector. The most common type of additional operation is some form of contracting.The aim for this degree project is to answer the following question: which problems and key factors exists within combination operations? The main topic will be within coordination and management questions within agricultural companies with an additional operation.Litterateur written earlier within this subject will be used in this thesis. Mainly litterateur which contains information about combination companies and diversification of some sort. There are also other theories used in this thesis such as; resource based theory and decision making theory in order to understand the problems and key factors within combination companies.In order to investigate the aim of this thesis we have chosen to perform two qualitative interviews with the managers of two different combination companies.

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.

Inadequate data quality has a negative effect for organizations, however utilization of modern technology and data analysis may shape new values for organizations. Our research has found that the quality of information in field reports for error reporting varies significantly. In many cases, the information in the field reports are deficient in such way that the field report need additional information from the sender, thus risking prolonging lead times in the error reporting process. More efficient use of information has become possible with today?s technology.

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.

In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.

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..

The purpose of this study is to establish how a few youngsters have experienced their time in contact families and which, if any, significance their respective ?contact families? has for them today. The study aims to determine the life situation in the youth?s families at the time support through ?contact families? was initiated and the youths? own view of the reasons for this support. We also want to shed light on the meaning that the contact families had on the youth; considering both positive as well as negative meaning.

This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

This thesis is about adware, which is very popular today. The adwares are used to, among other things, down- and upload files from other users on the Internet. One thing that most users of such programs are not aware of is that many of the adwares contain spyware. These spywares install themselves simultaneously with the adwares. Two of the spyware features is to generate pop-ups in the web browser and to direct advertisment from the users web habits.
