1. 1. Performance Indicators. A performance prediction method for moisture safety design

   Författare :Veronica Yverås; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Artificial Neural Network; Performance prediction; Moisture safety;

   Sammanfattning : The aims of this research project is to develop and gain knowledge about a different approach to moisture safety design based on AI in order to attain healthy buildings and relate this new approach to current practice and prospective users. Secondary data (data produced for some other purpose) was used to train Artificial Neural Networks (ANN) to predict the performance of outdoor ventilated crawl-spaces regarding microbiological smell, mould and rot.

3. 2. Performance Metrics for Sustainability Value

   Författare :David Sundfors; Hans Lind; Abukar Warsame; Stefan Olander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fastigheter och byggande; Real Estate and Construction Management;

   Sammanfattning : The trend that started with Green Building has moved on into Sustainable Building. But how do we know that something is really sustainable? This project started out with the intention to find a small set of performance indicators for commercial buildings, which could be continuously measured and monitored over time, which would give a good indication of the level of sustainability of the building and as such, and be presented as an additional part in a valuation.

4. 3. Integrated Control of Heat Pumps

   Författare :Fredrik Karlsson; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; variable speed compressor; superheat; electronic expansion valve; optimisation; performance indication; control; heat pump; energy efficiency;

   Sammanfattning : The purpose of the work presented in this thesis is to investigate the potential and prerequisites for improved energy efficiency of heat pump systems using efficient components and proper methods for optimisation of operation. The background is that several investigations have reported on possibilities for increased energy efficiency of heat pumps if variable-speed capacity control is used instead of conventional on/off control.

5. 4. Physical performance, physical activity, body composition and exercise training in adults with congenital heart disease

   Författare :Camilla Sandberg; Bengt Johansson; Karin Wadell; Lena Jonasson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult congenital heart disease; physical performance; physical activity; body composition; exercise training; sjukgymnastik; Physiotherapy;

   Sammanfattning : Background Adults with congenital heart disease (CHD) is a growing population and related to advances in surgical and medical treatment, they now outnumber the children with corresponding lesions. Since a congenital heart lesion often results in reduced exercise capacity, this population is a potential target for physiotherapy. LÄS MER

7. 5. Linear Quadratic Gaussian Controllers for Feedforward Active Noise Control : Pushing Performance and Moving Towards Adaptive Control

   Författare :Annea Barkefors; Mikael Sternad; Anders Ahlén; Lars-Johan Brännmark; Bengt Carlsson; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active noise control; ANC; LQG; feedforward control; sound field control; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Active noise control is a research area focused on using destructive interference of sound fields to attenuate undesired noise. Methods for active noise control are best suited for low frequency noise, as the complexity of the problem grows rapidly with frequency. LÄS MER
