Most Swedish housing is ventilated by a mechanical exhaust ventilation or natural ventilation. In both of the ventilation system the fresh air is usually added through vents in the outer wall straight into the bedroom and living room. The solution may involve a risk of draft experience and poor thermal comfort in the vicinity of the inlets. One measure that the residents can then take is to

Calculated deformations in glulam beams caused by moisture are based on linear moisture profile, this does not reflect reality. This report contains of a study where the moisture induced deformations are measured in three different test setups, simulating more realistic moisture exposure. After the beams are seasoned in RH 30 and 95 % the climate was changed, one group was in a moistening phase an

Danogips has introduced tongued and grooved gypsum boards which can be used regardless of the distance between the studs in the framework. The goal of this thesis is to evaluate the material properties of the new gypsum product and compare it to conventional gypsum walls. Literature studies and three different experiments are carried out. The stiffness of the construction is measured by applying a

A progressive collapse implies a structural failure initiated by a local damage which subsequently develops, as a chain reaction, into a failure of either the entire structural system, or only a part of it. The collapse of the Ronan Point building in London 1968 prompted numerous efforts to develop structural design criteria to prevent progressive collapse. Improved design procedures with the inte

Problems considering vibrations influence on comfort and health have been known for long and extensive efforts have been carried out to describe them. However, the appearance of these problems in the appliance of concrete slabs is a new phenomenon which started to arise due to the development of prestressing. For this thesis some of the existing knowledge has been applied to determine the maximal

This Master Thesis has been written in coliabaration with Modulenthus and Lund Institute of Teclnology. This thesis has two pm-poses: To show how a VR-mode! best can be created by evaluating different programs and to examine the compatibility between ADT and Archicad.

I det moderna affärsklimatet är det svårt att klara sig utan någon sorts informations eller affärssystem. En av de vanligaste typerna av dessa system är ERP-system, som ämnar stödja företags verksamhet genom att samla all information på en plats. Att arbeta med implementering av ERP-system är ett stort och svårt åtagande som går ofta fel. Syftet med denna uppsats är att ta reda på varför detta ske

Denna uppsats är en studie av Sanxiadammen vid Yichang i den kinesiska Hubeiprovinsen. Jag redogör inledningsvis för hur projektet började och slutade, i syfte att ge läsaren de basfakta som behövs för att lättare komma in i den huvudsakliga texten. Även miljöpåverkan som ett resultat av de miljöfarliga utsläpp som förekommit i Yangzifloden har studerats för att bättre förstå konsekvenserna av damThis essay describes the effects that have come from the construction of the Sanxia Dam, Yichang, Hubei province. I begin with a brief description of how the dam project started and ended, in order to give the reader the basic knowledge that is needed for a better understanding while reading the rest of the text. Focus lies on the project's impact on the environment, such as the pollution of t

How people walk is very individual and even their personal style of walking may change throughout their lives. But it could be that the people of the same sex with the same height, weight and age would have a way of walking with great similarities in terms of feet angle and length of the stride. This project examined the geometric walking pattern experimentally of 150 men between 170 and 190 cm. E

Abstract In this thesis we present a method for tracking a depth sensor and building a 3D model in real-time. The tracking will be done using the current estimated 3D model. We will show that this approach gives more accurate results and is more robust than the well-known KinectFusion approach. It will also be shown how to colourise the 3D model in real-time. In this work we will study different e

I takt med att det offentliga i allt större utsträckning väljer att köpa in varor och tjänster från marknaden ökar också risken för anbudskarteller. I arbete med att förhindra och beivra uppkomsten av dessa otillåtna samarbeten kompletteras upphandlingslagstiftningen av konkurrensrätten. Den förstnämnda kan i detta hänseende sägas reglera den miljö vari vilken anbudskarteller uppkommer medan den sAs the public sector increases the sourcing of goods and services from the market place rather than providing them in-house, the risk for collusive behaviour in the form of bidding cartels increases. To prevent such illegal collaboration, public procurement law are supplemented with competition law. The role of the public procurement law is to regulate the environment where cartels may emerge, whi

Since the collapse of the Warszawa pact Central and Eastern European countries have changed their political agenda towards Western European countries (and the EU) by showing a political will to establish a (new) society based on Western principles and values. Simultaneously the Member states of the European Union have coordinated their foreign and security policy and shown an interest in solving d

This thesis is supposed to form the basis for a future productian of a two-storey wooden house called "Villa Nöbbele". The house is designed for construction on si te. An estimation of cost of "Villa Nöbbele" has been made and to get an object for comparison regarding the construction procedure, bu t above all regarding the price, a house of the Modulent collection has been stu

A model for calculating crack widths in mesh reinforced shell structures with arbitrary directions of the reinforcement. The model is compiled into a spreadsheet for practical use. Comarative examples are made between new and traditional methods.

Modulenthus is a company in the wood house industry that builds houses in volumes. Volume building means that Modulenthus builds predecorated house volumes in a factory and transports these to the building sites where they are being put together to complete detached houses. The purpose of these Master Thesis is that, on the basis of Modulenthus conditions and wishes, evaluate a possible using of a

Fastighetsbeståndet byggt mellan 1940-70, med tegelfasader av skalmurstyp, har omfattande skador på grund av rostande armering och kramlor. Anledningen är att de stålsorter som användes för armering och infästning inte var korrosionsbeständiga fram till 1980-talet. Initialt uppträder problemen över öppningar där armering finns i det understa tegelskiftet. Då täckskiktet är otillräckligt börjar stå

Modulenthus bygger sina hus enligt volymprincipen, vilket innebär att de olika elementen till stommen byggs på olika linjer inne i en husfabrik. Dessa element sammanfogas sedan till större volymer. När volymerna står färdiga kan fönster och dörrar börja monteras och det invändiga arbetet såsom kakling av badrum och iordningställande av kök påbörjas. De inplastade volymerna transporteras sedan ut t

Analysis and design of a frame can be done in two principally different ways. The first method, calculation according to first order elastic theory, is based on buckling lengthsand interaction relations. The advantage with this method is its simplicity. The difficulty lies in the determination of buckling lengths. The second method, calculation according to second order elastic theory, results in
