   Sammanfattning : The III-nitride materials, consisting of Al, Ga, In and N, have several physical properties that make them attractive for semiconductor devices in electronic and optic applications. A wide range of direct energy bandgaps (0.7 eV - 6.1 eV) can be obtained. LÄS MER

3. 22. Slack-Time Aware Dynamic Routing Schemes for on-chip networks

   Författare :Daniel Andreasson; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Network on Chip; Dynamic Routing; Router design; Routing algorithms; Slack-time; Electronics; Elektronik; Computer science;

   Sammanfattning : Network-on-Chip (NoC) is a new on-chip communication paradigm for future IP-core based System-on-Chip (SoC), designed to remove a number of limitations of today’s on-chip interconnect solutions. A NoC interconnects cores by means of a packet switched micro-network, which improves scalability and reusability, resulting in a shorter time to market. LÄS MER

4. 23. Performance Analysis and Design Space Exploration of On-Chip Interconnection Networks

   Författare :Abbas Eslami Kiasari; Axel Jantsch; Joerg Henkel; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The advance of semiconductor technology, which has led to more than one billion transistors on a single chip, has enabled designers to integrate dozens of IP (intellectual property) blocks together with large amounts of embedded memory. These advances, along with the fact that traditional communication architectures do not scale well have led to significant changes in the architecture and design of integrated circuits. LÄS MER

5. 24. Control and Optimization of Fuel Cell Based Powertrain for Automotive Applications

   Författare :Qian Xun; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power distribution; Cut-off frequency; Fuel cell; Chance-constraint co-design optimization; Supercapacitors; Convex programming; Electric vehicles; Load disturbance compensator; DC-link voltage; Robust co-design optimization; Batteries;

   Sammanfattning : Fuel cell powered electric vehicles, with fast-refueling time, high energy density, and zero CO2 emissions, are becoming a promising solution for future fossil-free transportation. However, the relatively slow dynamic response and the inability of recovering the regenerative energy make vehicles solely powered by fuel cells not an immediately attractive solution. LÄS MER

7. 25. Genetic design for facilitated production of human peptide hormones inEscherichia coli

   Författare :Per Jonasson; KTH; []
   Nyckelord :;

   Sammanfattning : Genetic strategies have become important in the design ofefficient processes for production of recombinant proteins.When constructing a production scheme, inherent properties,purity and quality requirements, as well as the final use ofthe protein, have to be considered. LÄS MER
