2. 1. White Layer Formation during Hard Turning of Through-Hardened Martensitic and Bainitic AISI 52100 Steel

   Author : Seyed Hosseini; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; white layers; residual stresses; phase transformation; dynamic recovery; bainite; dynamic recrystallization; carbide deformation; retained austenite; steel; martensite;

   Abstract : Increased demands for flexible manufacturing lines, shorter cycle times and reduced impact on the environment drives the need for optimization of today’s manufacturing. For machining of hardened steel parts (>45 HRC), grinding has been the obvious choice for many decades. However, hard turning has often been considered as a replacement due to e. READ MORE

4. 2. Integrative Analysis of Dynamic Networks

   Author : Vinay Jethava; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lovasz theta function; dynamic networks; integrative analysis; probabilistic graphical models; support vector machines; graph kernels;

   Abstract : Networks play a central role in several disciplines such as computational biology, social network analysis, transportationplanning and many others; and consequently, several methods have been developed for network analysis. However, in many cases, the study of a single network is insufficient to discover patterns with multiple facets and subtlesignals. READ MORE

5. 3. Millimeter-wave Communication and Radar Sensing — Opportunities, Challenges, and Solutions

   Author : Sining An; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic; BiCMOS; OFDM; synchronization; Millimeter-wave; range accuracy; radar; communication system; micrometer; high data rate; frequency divider; wideband; phase modulated; monitoring; carrier recovery; distance measurement; mobile network; sensing; fast Fourier transformation FFT .; SiGe;

   Abstract : With the development of communication and radar sensing technology, people are able to seek for a more convenient life and better experiences. The fifth generation (5G) mobile network provides high speed communication and internet services with a data rate up to several gigabit per second (Gbps). READ MORE

6. 4. Recovery from Acidification - Policy Oriented Dynamic Modeling

   Author : Liisa Fransson; Institutioner vid LTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Petrology; mineralogy; geochemistry; Petrologi; mineralogi; geokemi; Chemical technology and engineering; target loads; sea-salt episode; sulfate adsorption; SAFE; LRTAP; critical loads; integrated assessment;

   Abstract : Dynamic biogeochemistry models are important tools for determining the time-scales of recovery from acidification. In the review process of the 1999 UNECE LRTAP Gothenburg protocol, results from dynamic models will probably be included when determining further reductions of acidifying emissions. READ MORE

7. 5. Sustainable building ventilation solutions with heat recovery from waste heat

   Author : Behrouz Nourozi; Sture Holmberg; Adnan Ploskic; Qian Wang; Shia-Hui Peng; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wastewater heat recovery; balanced mechanical ventilation; defrosting reduction; heat recovery efficiency; thermal load shifting; renewables; Byggvetenskap; Civil and Architectural Engineering;

   Abstract : The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss. READ MORE
