2. 1. Thermal Issues in Testing of Advanced Systems on Chip

   Author : Nima Aghaee Ghaleshahi; Zebo Peng; Petru Eles; Jaan Raik; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SoC test; test scheduling; Adaptive test; Temperature awareness; Process variation; Thermal simulation; 3D stacked IC 3DSIC test; Burn-in; Temperature gradients; Temperature Cycling Test; Test Ordering;

   Abstract : Many cutting-edge computer and electronic products are powered by advanced Systems-on-Chip (SoC). Advanced SoCs encompass superb performance together with large number of functions. This is achieved by efficient integration of huge number of transistors. READ MORE

4. 2. New Test Arrangement for Measuring Electrical Treeing in Polymers

   Author : Ramona Huuva; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Voltage stabilisers.; Wire-plane configuration; Polyethylene LDPE; Needle electrode; XLPE ; Electrical treeing;

   Abstract : Electrical treeing in high voltage cable insulation has been studied for a number of years and today the mostly used laboratory test set-up is the needle-plane electrode configuration. In this thesis a different type of electrode configuration is described. READ MORE

5. 3. Impediments for Automated Software Test Execution

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; software engineering; software testing; empirical software engineering; impediments; industrial research; empirical research; test execution; test automation; test execution automation; Computer Science; datavetenskap;

   Abstract : Automated software test execution is a critical part of the modern software development process, where rapid feedback on the product quality is expected. It is of high importance that impediments related to test execution automation are prevented and removed as quickly as possible. READ MORE

6. 4. Distributed Topology Inference for Power System Applications : Algorithms and architectures utilising industry standards

   Author : Nicholas Honeth; Lars Nordström; Valeriy Vyatkin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substation automation systems; IEC 61850; electrical topology; electrical engineering; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The electrical transmission and distribution system is undergoing unprecedented changes to meet the need for a carbon emission-free global energy system. An expected increase in the portion of end-user energy use in the form of electricity and need to integrate renewable energy sources into the power grid on a large scale require major changes in how power grids are operated and controlled.
