2. 1. Energy Efficient Air Quality Solutions for Vehicle Cabins

   Author : Dixin Wei; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate system; private car; measurements; particulate matters; CO2; simulations; air quality; air filter; UFP; filter status; energy use; vehicle cabin;

   Abstract : Maintaining a good air quality level is essential for reducing potential health risks for human beings. Vehicle cabin is one common environment where people spend increasing amount of time in modern societies. It’s an environment challenged by elevated pollutants from surrounding traffics, especially small particles like PM2. READ MORE

4. 2. Annoyance, quality- and safety aspects of sound in truck cabins

   Author : Anders Genell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spectral balance; low frequency; product sound quality; annoyance;

   Abstract : For heavy vehicles the interior sound environment is still more or less just apassive result of the engineering of the different parts that make up the vehicle,although measures are taken to keep sound pressure level within legislatedboundaries. Additionally, the sound inside truck cabins is dominated by itslow frequency (LF) content, and is hence prone to impair task performance andreduce wakefulness as well as cause general annoyance and different adversehealth effects.

5. 3. Radiation properties of coil-coated steel in building envelope surfaces and the influence on building thermal performance

   Author : Ali Joudi; Bahram Moshfegh; Mats Rönnelid; Harald Svedung; Mathias Cehlin; Runming Yao; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy and Built Environments; Energi och samhällsbyggnad;

   Abstract : Recent studies have shown that the optical properties of building exterior surfaces are important in terms of energy use and thermal comfort. While the majority of the studies are related to exterior surfaces, the radiation properties of interior surfaces are less thoroughly investigated. READ MORE

6. 4. Active Noise Control in Aircraft : Algorithms and Applications

   Author : Sven Johansson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active noise control; feedforward control; filtere-x lms algorithm; complex lms; multichannel system; multiple reference; aircraft; headset;

   Abstract : The thesis consists of five papers which are divided into three main parts. Parts A and B deal with active noise control in a propeller aircraft application, whereas Part C deals with active noise control in a helicopter application. READ MORE

7. 5. Embedded Measurement Systems

   Author : Lars Bengtsson; Göteborgs universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microcontroller; measurement system; direct sensor-to-controller; time-to-digital converter; phase detector; lock-in amplifier;

   Abstract : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. READ MORE
