Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR

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.

Environmental variables determining the occurrence of the red-listed Carbonicola anthracophila and C. myrmecina in boreal forests

The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.

"Vi är inte byggda för att ta in video" Utmaningar med video i räddningsarbete

THE CONSTANT IMPROVAL AND REFINEMENT OF THE MOBILE TECHNOLOGY HAVE MADE IT POSSIBLEto use video in settings where such use couldn't be motivated before, due to economicaland practical reasons. The purpose of the study was to identify and explore possiblechallenges in interorganizational use of video during emergency response work. Thiswas done by a case study of a system designed for the use of video in such situations.The study focused on operational challenges for the fire and rescue services and thehealthcare organisations, where the main challenges identified were intended to beanalysed and discussed in terms of design. The empirical results were gathered throughqualitative interviews with representatives from the fire and rescue services and thehealthcare organisations in Göteborg. This material made it clear that contextual aspectsof emergency response work lead to a couple of challenges connected to the use of videoin such situations.

Anoto - Standardsättningsstrategier utifrån ett litet företags perspektiv

Anoto är ett litet företag som, med hjälp av ett koncept bestående av en så kallad digitalpenna och tillhörande papper vill etablera en global de facto standard för pappersbaserad digital kommunikation. Hur har Anoto gått tillväga i sitt försök att etablera en de facto standard för pappersbaserad digital kommunikation? Syftet med uppsatsen är utföra en fallstudie av Anotos försök att etablera en de facto standard för pappersbaserad digital kommunikation. Målsättningen med fallstudien är att beskriva och analysera denna standardiseringsprocess. Vi har kommit till slutsatsen att för ett företag som Anoto kan ha en chans till standardsättning och att knyta allianser med stora internationella företag beror helt på i vilken utsträckning de lyckats uppnå utväxling, skapa tydliga indirekta nätverkseffekter, bygga upp förväntningar för konceptet, samt koordinera nätverksansträngningarna.

Snabb och säker roaming i WLAN

This thesis investigates how Ericsson AB should do to achieve fast and secure handover when roaming in a WLAN. It also provides a security analysis of the system that the wireless access point is part of. The reason for this is that Ericsson is selling an access point called the ABS 2200 aimed at the public hotspot market. The premise was that they wanted a standardized way of handling the roaming issue. At the outset the 802.11F standard looked like a good alternative (in fact the only standardized alternative).

Hela världen i en matris

Of all observable societal trends, the proliferation of standardizing processes is striking. Auditing standards are an illustrative example of this. Not only privately owned companies must today make available numbers and key figures to satisfy needs of information and knowledge. Government agencies are increasingly conforming to this trend, adopting standards for quality assurance and monitoring, producing numbers and annual reports ? despite their somewhat ambiguous task and role.

Granskning av svensk standard för dimensionering av stålfiberbetongkonstruktioner : Jämförelse av plattor enligt SS 812310 och SS-EN 1992

En svensk standard, SS 812310­ ? Dimensionering av fiberbetongkonstruktioner, har nyligen tagits fram som skall säkerhetsställa kvalitén och underlätta dimensioneringen av stålfiberbetongkonstruktioner. Tidigare har det inte funnits en dimensioneringsstandard som täcker in området stålfiberbetong. Det har varit upp till enskilda konstruktörer att dimensionera utifrån metoder angivna ur ?Svenska Betongföreningens rapport nr 13?.

Enklare korglutning

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

Framtagning av en informationssäkerhetspolicy

This report was made for the company HordaGruppen AB to investigate how information security was handled. This report fits in the Master program of Internet Technology at School of Engineering in Jönköping University in Sweden.The question at issue was how you protect your information against different threats. One question was how to make an information security policy and which guidelines you can follow in the Swedish Standard, SS-ISO/IEC 17799:2000.Another question was to investigate the information sources at the company and which threats there are against it.The work begins with a presentation about information security for the chief of information and the chief of quality in the company. The next thing was to do a survey of as thing are at present with a tool from Länsteknikcentrum called ?Infosäkpulsen?.

Intäktsredovisning i svenska byggföretag -En studie kring IFRIC 15 och IASB:s föreslagna standard och dess påverkan på intäktsredovisningen i tre svenska byggföretag

One of the most crucial entries in the financial statements is revenue. Despite the importanceof revenue a lot of mistakes are made concerning this entry because of the extensive room forjudgements. Especially in the construction companies where a lot of differences exist due tothe fact that different standards are used for similar business transactions.The research concerning IFRIC 15 and the new upcoming standard for revenue recognition isnot very extensive. Studies including both IFRIC 15 and the new standard are even morelimited. Therefore this study aims to compare the effects of IFRIC 15 and the new upcomingstandard for revenue recognition, Revenue from Contracts with Customers, in three Swedishconstruction companies.

Full goodwill method: Effekter av ändrade redovisningsprinciper för goodwill

The main aim of this paper is to consider the possible effects of a transition to a new accounting standard for goodwill. According to IASBs Exposure Draft of Proposed Amendments to IFRS 3 Business Combinations there is an inconsistency in the currently used purchased goodwill method. The full goodwill method is considered to be a superior alternative and is therefore suggested to become the standard from 2007. This paper comprises a quantitative study of the effects on certain key ratios for companies listed on the Stockholm Stock Exchange, arising due to the proposed transition. The period examined is 2004 and 2005.

THE FUN IS OVER - Idéer om motståndsstrategier och dess legitimitet i Ulrike Meinhofs krönikor ?Counter-Violence?, ?From Protest to Resistance? och ?Setting Fire to Department Stores?, publicerade år 1968 i tidsskriften konkret.

AbstractI denna undersökning tolkas motståndsstrategier i Ulrike Meinhofs skrivna texter.Undersökningsmaterialet består av engelska översättningar av tre krönikor publicerade i denVästtyska tidsskriften konkret under året 1968: ?Counter-Violence?, ?From Protest toResistance? och ?Setting Fire to Department Stores?.Syftet är att tolka Meinhofs syn på motståndsstrategier i de tre krönikorna. Detta görsgenom att först tolka det deskriptiva innehållet i krönikorna; det vill säga vad texterna säger.Tolkningarna görs både kronologiskt och komparativt utifrån vilken typ av motståndsmetodsom beskrivs, motståndsmetodens syfte eller riktadhet, samt värderingen av en specifikmotståndsmetod och dess resultat eller konsekvenser. Den komparativa tolkningen utgörsvidare av en fokusering på krönikornas potentiella skillnader, olikheter eller förändringar.Syftet är också att utifrån den kronologiska och den komparativa tolkningen diskuterakrönikornas performativa funktion; det vill säga vad texterna gör.Uppsatsen är teoretisk och anknyter till en genusvetenskaplig, metodologiskutgångspunkt som innebär att teori och metod inte skiljs åt. Uppsatsen omfattas också av ettepistemologiskt ställningstagande som innebär att gränsen mellan forskningens subjekt ochobjekt ifrågasätts och diskuteras.
