2. 1. Improvement of Thermal Comfort in Buildings through Passive Design

   Author : Marcelino Januário Rodrigues; Byggnadskonstruktion; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Sustainability; Energy Efficiency; Passive Design; Orientation; Shading; Ventilation; Materials; Temperatures; Thermal Comfort; Simulations; Retrofitting; Hot Humid Regions.;

   Abstract : In hot humid regions the high outdoor temperature has negative effects on the indoor temperature of buildings that are not designed to cope with the local climate. This leads to discomfort for the occupants. READ MORE

4. 2. Towards adaptive bogie design

   Author : Milad Mousavi Bideleh Seyed; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensitivity analysis; Optimization; suspension system; bogie; active control;

   Abstract : Suspension components play a crucial role in bogie dynamics behavior. In this regard, passive and active systems are developed to meet various design requirements. Adaptive suspension systems can adjust the bogie dynamics with respect to different operational scenarios and as a result improve the vehicle performance. READ MORE

5. 3. Cooling Strategies for Wave Power Conversion Systems

   Author : Antoine Baudoin; Cecilia Boström; Anne Blavette; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

   Abstract : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE

6. 4. Dynamic Resource Provisioning and Survivability Strategies in Optical Networks

   Author : Jawwad Ahmed; Lena Wosinska; Andrea Fumagalli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical networks; passive optical networks; wavelength; routing; Survivability; protection; restoration; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : Optical networks based on Wavelength Division Multiplexing (WDM) technology show many clear benefits in terms of high capacity, flexibility and low power consumption. All these benefits make WDM networks the preferred choice for today’s and future transports solutions which are strongly driven by a plethora of emerging online services. READ MORE

7. 5. Oscillator design in III-V technologies

   Author : Szhau Lai; Chalmers tekniska högskola; []
