När betongplattrambroar modelleras med moderna linjära 3D FE-modeller kommer stora dragkrafter att uppstå i brons tvärriktning från temperatur- och krympningslasterna. Dessa tvångskrafter är då mycket större än vad som har beaktats i de äldre 2D modellerna. Detta leder till att den tvärgående armeringsmängden, som beräknas i 3D-modellerna, är mycket större än vad som har varit norm innan. Denna avWhen concrete slab frame bridges are designed with modern linear 3D FE-models large tensile restraint forces will arise in the transversal direction of the bridge from the temperature and shrinkage loads. These restraint forces are much larger than those that are accounted for in the older 2D models. This leads to that the amount of transversal reinforcement, calculated in the 3D FE-calculations,

Broar som konstrueras utan kopplingar och lager fungerar så att de ska ta upp krafter via moment i ramhörn eller liknande. Integrerade broar i olika utformningar byggs över hela världen, och är populära på grund av dess enkla utformning och fördelar rörande livscykelkostnader. Vanligtvis tenderar dimensionerna, då i synnerhet ändskärmarna, att bli väldigt tunga och tungt armerade. Genom att tillgoBridges constructed without joints function to take care of forces by introducing bending moments to the stiff connections. Jointless bridges, also called integral bridges, in different appearances are built all over the world, and are popular due to their advantages regarding life cycle cost. Usually the dimensions of the structural parts, especially the backwalls, tends to be large and the eleme

Purpose – This paper attempts to improve our understanding of strategic asymmetric alliance formation within the field of entrepreneurship. We employ previous research findings on alliance formation and power relationships to examine the alliance formation tactics of startups. Accordingly, we aim to answer the question: ‘How do entrepreneurs build ties with comparably larger and more established c

The purpose of this study is to empirically test whether earnings management (both accruals-based and real) has an impact on the cost of public debt (approximated by credit ratings and bond yields) issued on the European bond market. Using a cross-sectional approach, accruals-based and real earnings management are estimated. The estimates are then used as explanatory variables in both an ordered r

This study addresses the question whether – and to what extent – work-related characteristics can explain the differences in retirement rates across thirteen European countries. To answer the research question from a gender perspective, a logistic regression and Blinder-Oaxaca decomposition analysis is conducted for the female and male population in each of the selected countries based on data fro

Volunteers fill an important function in the social work that constantly and in various ways goes on in our society. Without the volunteers' involvement there is a risk that many more people fall between the cracks than actually do, even in the Swedish welfare state. Since volunteers are people whose resources are finite, it is important to gain insight into what motivates, encourages and even

Sammanfattning Den här uppsatsen skrivs inom konkurrensrätt med fokus på Microsofts missbruk av dominerade ställning, på sin marknad inom IT och operativsystem vilket omfattar hela världsmarknaden. En central frågan är huruvida en marknadsdominerande plattformstillverkare kan gynna egna tilläggsprodukter (komplementära produkter) i sin virtuella infrastruktur, s.k. kopplingsförbehåll, utan att detAbstract This essay is written in the competition with a focus on Microsoft's abuse of dominant position in its market in IT and operating system which covers the entire world market. A central question is whether a dominant platform manufacturers can promote their own additional products (complementary products) in their virtual infrastructure, the so-called tying, without this constituting a

Denna artikel beskriver resultatet av ett examensarbete med syfte att utreda databasbaserade lagringsstrukturer för 3D-geodata. Projektet visade på vilka möjligheter det finns att skapa ett flexibelt databassystem där hantering så som lagring, uppdatering och addering av data är möjlig genom FME-skript. I och med den snabba teknikutvecklingen som skett det senaste årtiondet fanns tekniken för komThe interest in the production of 3D geo data has in recent years greatly increased, and many performers are interested in making use of 3D geo data for including urban design, planning, analysis, city models and web services. The use of 3D geo data can lead to an increased communication with the citizens thought interactive web maps. For example the user can slide around in a planned district or

The aim of the study is to develop a framework for symbolic simplification algorithms in the JModelica.org compiler. It should make the procedure of adding new algorithms to the compiler easier. Instead of the fixed order currently used in the compiler, algorithms will perform their simplifications to the model equations iteratively. This opens up the possibility for more simplifications being mad

Under förbränningsprocesser bildas mycket små partiklar av storleksordningen 1-100 nanometer och kallas därför nanopartiklar. Nanopartiklar utgör beståndsdelarna i det vi känner som sot. En nanometer är en etthundramiljontedels meter. Detta är svårt att föreställa sig. Istället kan man jämföra längden av ett par centimeter med längden av en resa runt ekvatorn. Nanopartiklar är så otroligt små atA simple investigation about the noise of the acquisition cards NI PXI-4495, provided by National Instruments, was performed. Standard deviations were calculated for data acquired from a signal generator, a constant voltage source and when the input channels were grounded, to estimate the noise. The obtained noise is in the order of a few millivolts when acquiring signals from the devices while th

The energy use in the building sector is increasing rapidly which contributes to the rise in global greenhouse gas concentration. Energy-efficient buildings are considered as healthy buildings due to the improved air quality and comfortable indoor environment. One million residential buildings were built in Sweden during 1965 and 1975 to minimize the acute housing shortage. This initiative was tak

Disease susceptibility mapping can produce risk maps showing predictive distribution of disease incidences. Hence, it is a useful tool for disease prevention. Data-driven approaches for disease susceptibility mapping model relationships and patterns from experience data. Therefore, using data-driven methods can facilitate a simple and direct approach towards disease susceptibility mapping. In th

I Sveriges storstäder råder idag stor bostadsbrist och byggandet av bostäder räcker inte till. Ett steg i arbetet med att möta det stora behovet av bostäder är att genomföra förtätningar. Lagar och regler har dock problematiserat och förhindrat många planerade förtätningsprojekt, vilket avsevärt försvårat arbetet med att bygga bort bostadsbristen. Ett av regelverken som utgör hinder mot förtätningA great shortage of housing is currently apparent in Sweden's major cities. To meet this need for housing, densification strategies are implemented. However, laws and regulations have complicated and prevented many planned densification projects, making the issue with housing shortage more difficult to address. One of the regulations that preclude densification of housing is the regulatory sys

The literature claims that elderly people need warmer indoor temperatures, short overheating periods and more light indoors. The thesis analysed a case study building in order to propose a solution of the façade design in the energy-efficient apartments for elderly people. Due to the simplified approach to the analysis, only specific apartments were chosen and optimized parts of design were shape

The Hanson Larson evolution model assumes that wave height grows or decays from an initial condition towards an equilibrium wave height through a simple exponential growth. The model uses wind input data, fetch length and depth measurements. Using this input parameters, it both determines the wave height and period values, thus predicts wave climate. The model is developed using deep water conditi
