When designing large complex steel structures numerical calculation methods are always used to some extent. The simulation technology of today is advanced and can with proper modeling technique provide detailed analyses which captures the structural response accurately. For most projects it is not reasonable to analyze a complete structure in exact detail and therefore simplified methods are used

Att människan påverkar klimatet och att utsläpp av växthusgaser värmer planeten är ingen nyhet. Byggsektorn stod 2015 för 18 % av Sveriges totala utsläpp av växthusgaser och 2018 lanserade Bygg- och anläggningssektorn en färdplan för att nå en klimatneutral värdekedja tills år 2045. Tidigare studier har pekat på att majoriteten av klimatpåverkan ifrån flerbostadshus kommer från driftskedet, men seThe emissions of greenhouse gases caused by the construction sector represented 2015 18 % of Sweden’s total greenhouse emissions and the sector had by 2018 published a plan on how to reach a climate neutral value chain by 2045. Studies have shown that the construction phase has become a larger part of the climate impact from new-built multi-family residential buildings than before, in, in relation

The idea of using the thermal mass of a building to maintain a more constant indoor climate is not new. This particular propertyof a building, including its exterior envelope, plays an important part in the reduction of peak power demands, which is becomingan increasingly urgent issue for the heating energy suppliers. The latest smart-grid technology creates new opportunities wherecommunication be

Virtual Network Operators lease bandwidth from different data carriers to offer well managed Virtual Private Networks. By using proprietary algorithms and leased resource diversity they can offer Quality of Service, at competitive prices, which is difficult to attain from traditional data network operators. Since maximizing the profit is a key objective for virtual network operators, in this paper

Det rapporteras många fall och spenderas årligen stora mängder av resurser på vattenskador i byggnader i Sverige. Vattenskador som uppkommer på grund av läckage och utströmning av vatten från installationer så som tappvatten-, avlopp- och värmesystem, utrustning så som kylskåp, frysar och diskmaskiner samt läckande tätskikt i våtrum. Vattenskador från dessa system orsakar allvarliga problem i bygg

In March 2023, the Swedish national Board of Housing, Building and Planning (Boverket) published a proposal for new ventilation rates in Sweden. The supply air should by this be calculated based on an equation using the heated floor area as the main input. It is set as optional to use less ventilation flow if this could be sufficient. However, in a questionnaire to Swedish practitioners within the

Water damage affects both residents and buildings. Issues include moisture, climate impact and repair costs that amount to immense resources. Because of these, immense resources research is important to undertake to reduce and limit the extent and effects of water damage. This study aimed to compile and review the literature on water damage in buildings. Literature distribution, the status, conseq

A study of the detection limits for the elements with Z = 15-92 in thick target steel surfaces using proton-induced X-ray technique has been performed. Samples were irradiated with a broad proton beam of 2 mm diameter and the X-rays were detected by a Si(Li) detector. Detection limits at levels down to the order of 10 ppm were achieved with simultaneous measurement of several elements. Mylar and

The Civil Engineering Laboratory is a collaboration between 12 different laboratories on the LTH campus. The Civil Engineering Laboratory is thus a platform that enables better collaboration and more advanced research and development to meet the needs of many. Within the Civil Engineering Laboratory we have many different instruments, testing machines but also a wide range of competencies to help

The SMErobot$^\texttrademark$ is an EU project aiming at giving small and medium enterprises the benefits of robotic automation. This thesis tries to solve the problem of teaching a robot how to grind a surface. The algorithm presented in this thesis reconstructs a surface by triangulating a point cloud. From this surface a path, covering the whole surface, is computed and translated into a RAPID
