Lungröntgen är en av de vanligaste röntgenundersökningar som görs i Sverige. Många gånger vid vanlig lungröntgen kan patologiska förändringar bara misstänkas så då används datortomografi (CT) undersökning av thorax som komplettering. Detta ger en ganska hög stråldos till patienten. En ny teknik, digital tomosyntes har visat sig kunna ge klart bättremöjligheter att ställa diagnos vid flera sjukdomstillstånd än vanlig lungröntgen utan att ge anmärkningsvärd högre stråldos. Några studier har visat att behovet av CT undersökningar kan reduceras med hjälp av denna teknik, vilket ger klart lägre stråldos till patienten.

The purpose of the study is to highlight educators' preferences and attitudes towards tablet in preschool by describing the use of this digital tool in the preschool educational activities. The use of tablet in preschool is in the study looked upon as a phenomenon. The description of the phenomenon is built on the analysis and interpretation of educators' statements about it. The research questions focus on the following aspects: educators' attitudes towards the tablet and its use in pre-school educational activities, the tablet's current area of use, the culture surrounding the use of this digital tool and the educators? statements about advantages and disadvantages of tablet's use in preschool.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

The concept of the photographic truth has had a special status for almost 200 years. Yet with the emerge of digital technology and especially digital photography there has been a loss of the particular connection photography has had in reference to reality. The aim of this study is to see in what ways digitalization has affected the credibility of photography from the perspective of professionals in the field of photography. The digital technology that has enabled the large-scale manipulation of photographies is not, however, the main reason for the decreased credibility of photography. The ongoing discussion about the available possibilities concerning digital imagery and manipulation has had a far more powerful effect on the concept of the photographic truth.

Bachelor thesis in political science by Malin Bergkvist, autumn 12.Title:Political governance for increased digital inclusion.Subtitle: Aspects of "governance" and "government".Supervisor: Joachim Åström. While digital inclusion is a hot topic in both academia and in policy circles, little research is done when it comes to governance issues. To help filling this gap, this essay asks which mode of governance is dominant in the field of digital inclusion. What aspects of governance "governance" or "government" is the dominant in the field of digital inclusion, and is it possible to see any difference in how the state governance is described by the government and perceived by other actors? To answer this overarching question, two sub queries are formulated and analyzed. First, what aspect of "governance" or "government" dominate when state governance of the area are examined based on how the government describes it? Second, what aspect of "governance" or "government? dominate when state governance are studied based on how the perceived by other actors and stakeholders active in the field.

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

I denna studie behandlas effort shapes kopplat till digital animation med syfte att undersöka om det finns en könsbaserad skillnad i uppfattning och bedömning av karaktärsdrag. De animationer som har producerats är grundade på effort shapes som härstammar från Laban Movement Analysis. Metoden som har tillämpats för att samla in data är en kvalitativ enkät med öppna frågor som har besvarats av tio män samt tio kvinnor. Resultatet visade att det finns en skillnad mellan könen i bedömningen av karaktärerna men inte i uppfattningen av karaktärsdragen..

A persistent problem in the construction industry is its low margins of profit. It is often difficult to earn money due to low efficiency and high costs. Logistics on the construction site answers for a large amount of these costs and it is therefore of interest to find new, more efficient logistic solutions. The purpose of this thesis is to compare two different logistic systems and further to evaluate which one that is the most efficient and profitable. A comparison is made between the traditional logistic systems used for years and a new logistic system developed by an industry association called BEAst.

The aim of this Masters thesis is to examine the library discourses concerning the phenomenon and concept of digital libraries in Swedish library press 1980-2002. What changes can be identified? The questions are: what is said about the conditions for the phenomenon; how is the concept of digital libraries used; who makes these statements; what are the relations between these discussions and the library context in which they are made? Five Swedish library journals, BBL/Biblioteksbladet, DIK-forum, Human IT, Svensk biblioteksforskning and Tidskrift för dokumentation, were examined. The method used was discourse analysis. The theoretical starting-point was Foucaults discourse theory.

Syftet med studien är att undersöka om en geografiskt begränsad marknad inom byggbranschen underlättar en implementering av Lean Construction. För att undersöka detta har jag utgått från två forskningsfrågor: vilken inställning de tillfrågade byggföretagen har till Lean Construction och hur de arbetar utifrån ett Lean-perspektiv? Utifrån ett antal grundprinciper från Lean Construction formades en enkät för datainsamling. Resultaten från undersökningen visade att respondenterna som bestod av platschefer/arbetsledare och underentreprenörer överlag tyckte att de områden som tagits upp var viktiga för en lyckad byggprocess och en stor del av respondenterna även arbetade utifrån ett Lean-perspektiv. Enkätundersökningen tog upp nio områden: samarbete, Visible Planning med detaljerade veckoplaner, Just-In-Time, slöseri, standardisering, Kaizen, innovationer, Last Planner med arbetsplanering och Percent Plan Complete från Last Planner konceptet.

Detta examensarbete utröner möjligheten att aktivt släcka ut en amplitudstark frekvensmodulerad sinussignal digitalt. Detta skall göras utan förkunskap om signalen gällande fas, frekvens eller amplitud. Eventuellt övriga, men betydligt svagare, sinussignaler i den analoga signalen skall inte påverkas nämnvärt av utsläckningen. För att lösa problemet har olika teorier för att lösa delproblemen med att mäta amplitud, fas och frekvens studerats varefter en lämplig kombination valts för implementering i en FPGA. Prestandan som uppmätts har jämförts med vad som teoretiskt är möjligt och vi konstaterar att metoden löser problemet på ett adekvat sätt men är i behov av en del förbättringar som diskuteras i slutet..

Syftet med denna uppsats är att bidra med ökade kunskaper om och bättre förstå hur fyra lärare använder och förhåller sig till digitala verktyg och digital teknik i undervisningen i svenska för senare år. Studien har en hermeneutisk fenomenologisk ansats och baseras på semistrukturerade kvalitativa intervjuer med informanter som har olika ämneskombinationer. Informanterna i studien har en jämn könsfördelning, är av olika åldrar och har varierande antal tjänsteår. Tematiseringsarbete som mynnade ut i fyra teman kan sägas karaktärisera lärarnas upplevelser av att använda digitala verktyg och digital teknik i undervisningen. Teman som växte fram och även utgör rubriker i resultatavsnittet var den utåtriktade tekniken, den betydelsefulla direktheten, den kontextförstärkande digitala tekniken och den svårkontrollerade användningen.

The problems caused by the current engine casing in aluminum for Volvo Buses Corp. are the mainfoundation for this degree project. Lack of maintenance combined with a construction poorlyadjusted for assembly has resulted in the fact that the engine casings rarely get reassembled whenthe service is completed.The degree project has mainly been following ?Olssons.

This report deals with activities that from a CSR perspective are considered to create a shared value for a medium-sized construction company in Sweden. The CSR definition used in the report is the European Commission?s since it reflects the valuecreating aspects of CSR, in contrast to the traditional philanthropic aspect of CSR.Companies in the building construction industry have difficulties identifying activities that create value in society and in the company. The aim with the project is to, from a CSR perspective, identify and evaluate value creating activities in a building construction company. The activities will be evaluated with respect to competitiveness and how they can be implemented into an organization.
