1. 11. Variations in dynamic properties of a steel arch footbridge : An experimental study

   University essay from KTH/Bro- och stålbyggnad

   Author : Martin Földhazy; [2018]
   Keywords : Damping ratio; Natural frequencies; Temperature; static mass; Human structure interaction;

   Abstract : This study separately investigates how temperature as well as two real load-situations affects the modal damping ratio and natural frequencies of a 64.9m span steel arch footbridge. Measurements of acceleration have been completed which covers a temperature span of  to . READ MORE

3. 12. Finite element analysis of temperature in hardening concrete using isothermal calorimetric data

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Author : John Mac; [2017]
   Keywords : isoconversion; isothermal calorimetry; thermal analysis; finite element method; numerical simulation; Technology and Engineering;

   Abstract : The produced heat in hardening concrete is of special importance to consider as the temperature rise within a large concrete structure can become such high that the structure may experience thermal cracking. With use of a simulation program that is based on the finite element method, the temperatures within the structure can be estimated to predict possible crack development. READ MORE

4. 13. Sustainable Thermal and Acoustic Retrofitting of Façade Walls

   University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Henric Lundh; [2017]
   Keywords : Thermal; Acoustic; Retrofitting; Façade; Sound; Sound reduction index; Sound level difference; Technology and Engineering;

   Abstract : Faced with an acute problem of housing options during the 1960s, the Swedish government introduced a nationwide campaign of ‘A Million New Homes’. In order to achieve the aim of the campaign, the construction of these homes depends on cheap and fast building methods which do not result in the homes being energy efficient nor are they equipped with good acoustical properties.

5. 14. Modelling and assessment of energy performance with IDA ICE for a 1960's Mid-Sweden multi-family apartment block house

   University essay from Högskolan i Gävle/Energisystem

   Author : Lierni Arnaiz Remiro; [2017]
   Keywords : retrofit; building’s energy performance; simulation; modelling; heat transfer; thermal bridge; IDA ICE; COMSOL.;

   Abstract : The present thesis has been carried out during the spring of 2017 on behalf of Gavlegårdarna AB. This is a public housing company in Gävle (Sweden) which is a large energy consumer, over 200 million SEK per year, and has the ambitious goal of reduce its energy consumption by 20 % between 2009 and 2020.

6. 15. A Technical Evaluation of Capacitive Level Sensors for use in Hemodialysis Machines on Chambers Filled with Dielectric Liquids

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Viktor Stevander; Viktor Petersson; [2016]
   Keywords : comb-finger; parallel fingers; capacitive sensor; Electrical engineering; Electric measurement; hemodialysis; dialysis machine; Technology and Engineering;

   Abstract : A series of tests were performed to explore the limits of two capacitive level sensors using the principle of parallel finger layout (sometimes called comb fingers) for sensing. The goal was to present a decision basis for Baxter to use when choosing a sensor to implement in their next generation hemodialysis machine. READ MORE
