2. 1. Electronic Labyrinths : An Archaeology of Videographic Cinema

   Author : Jonathan Rozenkrantz; Trond Lundemo; Malin Wahlberg; Patricia Pisters; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; videographic cinema; video images in films; media archaeology; imaginary media; media imaginaries; live television drama; video therapy; video surveillance; video art; reality TV; mediated memories; media history; YouTube; retro; analogue nostalgia; filmvetenskap; Cinema Studies;

   Abstract : This study scans six decades of film history in search for video images, the imaginaries within which they are framed, and (taking cues from the archaeological methods of Friedrich Kittler and Michel Foucault) their technical, historical, and institutional conditions of existence. The British experimental science fiction film Anti-Clock (Jane Arden and Jack Bond, 1979) revolves around a video device with the capacity to confront subjects with their own repressed memory images.

4. 2. Electronic Properties of Diamond

   Author : Markus Gabrysch; Jan Isberg; Mats Leijon; Johan Hammersberg; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; CVD diamond; wide-bandgap semiconductor; time-of-flight; pair-creation energy; electronic devices; detector; Elektronik; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Electricity; Esp The Study Of Transients and Discharges; elektricitetslära; ssk studiet av transienter och urladdning;

   Abstract : Diamond is a semiconductor with many superior material properties such as high breakdown field, high saturation velocity, high carrier mobilities and the highest thermal conductivity of all materials. These extreme properties compared to other (wide bandgap) semiconductors make it desirable to develop single-crystalline epitaxial diamond films for many electronic device and detector applications.

5. 3. Cooperative Spectrum Sharing and Device-to-Device Communications

   Author : Serveh Shalmashi; Ben Slimane; Jens Zander; Robert S. Karlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The steep growth in the mobile data traffic has gained a lot of attention in recent years. This growth is mainly the result of emerging applications, multimedia services, and revolutions in the device technology. With current deployments and radio resources, operators will not be able to cope with the growing demands. READ MORE

6. 4. Microwave power device characterization

   Author : Kristoffer Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; statistical estimation; self-heating; Silicon Carbide; Gallium Nitride; mixer; thermal resistance; wide bandgap; microwave; error-correction; small-signalmodel;

   Abstract : The first part of the thesis covers work done on device characterizationmethods. A statistical method for estimating small-signal model parametersin FET-models was proposed. A maximum likelihood estimator wasderived and the new method was compared to a standard direct extractiontechnique. READ MORE

7. 5. Ultrahigh-Voltage Silicon Carbide Device Performance, Requirements, and Limitations in High-Power Applications

   Author : Daniel Johannesson; Hans-Peter Nee; Staffan Norrga; Muhammad Nawaz; Alberto Castellazzi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 4H-SiC; Current Filamentation; Device Characterization; Dynamic Avalanche; JTE Structure; Junction Termination Extension Design; SiC BJT; SiC GTO Thyristor; SiC IGBT; SiC MOSFET; SiC PiN Diode; Silicon Carbide; TCAD Simulation; Wide bandgap device; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The increased awareness of the on-going climate change accelerates the electric energy system transformation from fossil-fueled power sources towards systems with larger portions of renewable energy sources. Moreover, the grid infrastructure requires reinforcements to cope with increasing electrical energy demand. READ MORE
