This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

Lungcancer är den femte vanligaste cancerformen i Sverige och ofta blir patienten diagnostiserad i ett senare stadium. Inom radiologin utförs oftast först en konventionell tvåbilds-lungröntgen och sedan en datortomografiundersökning (DT) för att med säkerhet kunna diagnostisera och mäta tumören. Eftersom patienten kan genomgå många olika röntgenundersökningar i samband med sitt sjukdomsförlopp, har det därför blivit vanligare att använda sig av digital röntgentomosyntes (DTS). DTS innefattar en betydligt mindre stråldos till patienten i jämförelse med datortomografi men är ändå en mer sensitiv undersökningsmetod i jämförelse med konventionell lungröntgen. Syfte: Vårt syfte var att undersöka om DTS är diagnostiskt försvarbart jämfört med en DT-undersökning, DTS möjligheter och begräsningar vid lungcancerdiagnostik.

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

This thesis focuses on the construction of drystone walls in the county of Sm?land, as well as their historical value and significance to the county. In Riksantikvarie?mbetets Plattform Kulturhistorisk v?rdering och urval, a directory for historical evaluations of buildings and objects, the first clause is to describe the object and its history. When trying to do this, the lack of literature focusing on the constructional elements of drystone walls and their history became an issue and is what prompted the writing of this thesis. With a study of different handbooks, a compilation of the constructional elements of the walls were put together.

Sammanfattning: Det är minst lika många människor som besöker arrangemang och gudstjänster i kyrkor som besöker idrottsevenemang. Det behövs studiogudstjänster dock sänds det allt färre Tv-gudstjänster direkt från kyrkor och medlen för att göra detta är också på väg att minskas. Många som ser dessa gudstjänster har av olika orsaker inte möjlighet att besöka en kyrka. Detta kan t ex bero på funktionshinder och sjukdom men också att många äldre har svårt att förflytta sig och se gudstjänster live. Ett sätt för kyrkorna att nå ut på bredare front skulle kunna vara att använda sig av Internet som media.Syftet med uppsatsen är att genom intervjuer, användningstestning och slutligen prototyptestning, ta fram en lösning för digital överföring av ljud och bild från ett ställe till ett annat via ett IP-nätverk och finna en avvägning mellan det tekniska och användbarheten då användaren har begränsad teknisk kunskap.Vid datainsamlingen användes en kvalitativ forskningsprocess med intervjuer och observation som insamlingstekniker.

Urination is a biological need but the routines surrounding urination are culturally specific and ever changing. This makes the organization of public space an important part in deciding what actions are made possible for the people in it. This paper considers women?s public urination and the possibilities to merge the need to urinate and the construction of the female body as feminine.A number of texts that describe the construction of the female body and identity as both gendered and socially produced are analysed in relation to women?s experiences of incontinence. Incontinence as a medical diagnosis is by this becoming possible to question, and may be seen as one of several strategies used to manage both the organization of the public space and the expectations of the female body to be a docile body.The conclusion is that a woman who wants to enter public space has the following options when it comes to the need to urinate:To strive for the feminine ideal.

TitleEnergy-efficiency ? of slab blocks built in the sixtiesAuthorsRichard Sandahl and Kim SöderbergEducationHalmstad University, Section for economy and technique Construction Engineering 180 ECTSSupervisorMargaretha Borgström, Universitylector construction physics, Halmstad UniversityContact person at HFABUlf Johansson Heating, sanitation and energy co-ordinatorReportExamination paper at the construction engineering program is performed in cooperation with HFAB (Halmstad real estate concern Inc.)AimThis examinations work is done in cooperation with HFAB and there project on the block around the street Maratonvägen. HFAB:s dwelling stock on this area are going through a bigger renovation and in relation to this they are looking on the possibilities to make this building more energy efficient. That is why this examination paper has as purpose to answer the question if it is possible to make slab blocks built in the sixties more energy efficient. This is done by calculate energy efficient measures on a chosen apartment block at Maratonvägen in Halmstad, in an energy and expense perspective.MethodThe examination paper is based on different methods, mainly calculation but also qualitative conversation studies, economic calculations and literature studies.

In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

With the digital revolution within video games, the need for Digital Rights Management (DRM) has increased significantly, alongside with the increasing problem of copyright pirates. To counter pirates, DRM was created to prevent illegal copying of software, this to ensure that the Distributors received an income for their work. DRM has, since the start of its use, been getting, a lot of bad criticism from the users of the software protected by DRM. The main function of this paper is to describe the creation and development of DRM by analysis of the vision of different groups on this phenomenon. The main questions are as follows, is it possible to define the very reason for why DRM was created and if so, can its development through time be defined too? What differences in opinions are there when it comes to DRM, counting the two major groups of creators, sellers, distributors (referred to as distributors) versus individual users (referred to as consumers)? In what way will the research results suggest that the future DRM will develop?The development has gone from solving puzzles in a handbook to start the game each time the user wants to play, to serial numbers that is needed during the installation of the game.

This thesis tries to clarify why more houses such as passive houses is not built and at the same time the differences is described with the conventional construction as a starting point. Sweden has set environmental objectives to reduce energy consumption in buildings by 50 percent by the year 2050 compared to 1995. The passivehouse concept could have a significant role, particularly in the reconstruction of buildings with high energy consumption. For sustainable building the passivehouse technology is an economically viable concept while benefiting the environment. Initially an introduction is given of the background to the problem, purpose and objective of the thesis.
