1. 1. Techniques to Cancel Execution Early to Improve Processor Efficiency

   Författare :Mafijul Islam; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; processor design; energy-efficiency; narrow-width cache; instruction reuse; zero-value cache; resource-efficient; narrow-width load; complexity-effective; small value locality; register file cache; frequent value locality; trivial instruction; silent load; high-performance; zero load;

   Sammanfattning : The evolution of computer systems to continuously improve execution efficiency has traditionally embraced various approaches across microprocessor generations. Unfortunately, contemporary processors still suffer from several inefficiencies although they offer an unprecedented level of computing capabilities. LÄS MER

3. 2. SiC Varactors for Dynamic Load Modulation of Microwave Power Amplifiers

   Författare :Christer Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear characterization; varactors; active load-pull; power; microwave; amplifier; dynamic load modulation; SiC; energy efficiency;

   Sammanfattning : The rapid consumer adoption of mobile services is leading to an exponential growth in wireless data traffic. In order to accommodate more concurrent high data-rate users, the required complexity of transmitting radio base station (RBS) power amplifiers (PAs) is increasing. LÄS MER

4. 3. Lokal kollektivtrafik på samhällsekonomisk grundval

   Författare :Anders Ljungberg; Jan Owen Jansson; Bengt Mattsson; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Local public transport; Cost-benefit analysis; Straighter bus-routes; Staggered school hours; Peak-load pricing; Zero fare; Lokal kollektivtrafik; Samhällsekonomisk kalkyl; Varierad skolstart; Optimal prissättning; Nolltaxa; Economics; Nationalekonomi;

   Sammanfattning : Förutom i Stockholm uppvisar den lokala kollektivtrafiken en nedåtgående trend i trafikutvecklingen, trots en årlig subvention om 10 miljarder kronor. Drift av lokal kollektivtrafik i mindre och medelstora städer baserat på samhällsekonomiska kriterier skulle bl a medföra en prispolitik som kräver en subvention om drygt 50%. LÄS MER

5. 4. Fatigue crack growth experiments and analyses - from small scale to large scale yielding at constant and variable amplitude loading

   Författare :Pär Ljustell; Fred L. Nilsson; Bo Alfredsson; Gunnar Härkegård; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fracture mechanics; fatigue crack growth; finite elements analysis; small scale yielding SSY ; large scale yielding LSY ; low cycle fatigue LCF ; crack tip opening displacement CTOD ; crack closure; potential drop method; constant amplitude load; variable amplitude load; inconel 718; stainless steel 316L;

   Sammanfattning : This thesis is on fatigue crack growth experiments and assessments of fatigue crack growth rates. Both constant and variable amplitude loads in two different materials are considered; a nickel based super-alloy Inconel 718 and a stainless steel 316L. LÄS MER

7. 5. Downlink Resource Allocation in Cooperative Wireless Networks

   Författare :Jingya Li; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; precoding design; load balancing; relaying; imperfect channel state information; imperfect synchronization; Coordinated multi-point transmission; I Q imbalance; resource allocation; fractional frequency reuse;

   Sammanfattning : Wireless cooperative networks, which is based on exploiting coordination among multiple access nodes, has been considered as a promising approach to improve the spectral efficiency, reduce the energy consumption, and extend the network coverage of future wireless communication systems. In practice, the actual benefit of multi-node cooperation is affected by a variety of factors, including the quality of channel state information (CSI), the constraints on the feedback and backhaul links, hardware impairments, resource allocation and data processing schemes.
