4. 2. The open absorption system : energy savings in different applications

   Author : Lars Johansson; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Abstract : The open absorption system is a technique that makes it possible to recover energy in different processes using moist air. In most applications the latent heat in moist air is difficult to recover because of the low temperature. Processes using outdoor air to carry away moisture therefore have high energy demands.

5. 3. Railway Open System Tribology

   Author : Yezhe Lyu; Ulf Olofsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wheel; Rail; Brake; Environmental conditions; Tribology; Noise; Particle; Hjul; Räl; Broms; Miljöförhållanden; Tribologi; Ljud; Partiklar; Machine Design; Maskinkonstruktion;

   Abstract : Tribology in the railway system is of increasing interest in the new railway era due to the demand for higher speed and load capacity. Since railway vehicles operate in an open environment, their performance depends greatly on temperature, humidity and natural and artificial contaminants. READ MORE

6. 4. Open Quantum Systems : Effects in Interferometry, Quantum Computation, and Adiabatic Evolution

   Author : Johan Åberg; Erik Sjöqvist; Sten Lunell; Vlatko Vedral; Uppsala universitet; []
