2. 1. Explainable and Resource-Efficient Stream Processing Through Provenance and Scheduling

   Author : Dimitrios Palyvos-Giannas; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Data Streaming; Scheduling; Provenance; Stream Processing;

   Abstract : In our era of big data, information is captured at unprecedented volumes and velocities, with technologies such as Cyber-Physical Systems making quick decisions based on the processing of streaming, unbounded datasets. In such scenarios, it can be beneficial to process the data in an online manner, using the stream processing paradigm implemented by Stream Processing Engines (SPEs). READ MORE

4. 2. Silicon Carbide Microwave Devices

   Author : Joakim Eriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SBD; high-power microwave devices; Silicon Carbide; diode mixer; wide band gap devices; physical simulations; resistive mixer; microwave devices; MESFET; Schottky diode;

   Abstract : This work deals with silicon carbide (SiC) microwave devices. It treats two devices; the Schottky diode and the metal semiconductor field effect transistor (MESFET). Different MESFET materials, fabrication processes, theoretical models for physical simulation, and device models are presented. READ MORE

5. 3. On the weightless economy: Evaluating ICT sectors in the European, Asian and African regions

   Author : Ibrahim Kholilul Rohman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; probit; Gini coefficient; Europe; economic growth; ICT sectors; panel cointegration; diffusion; Asia; Africa; panel data; broadband; input-output; production; weightless economy; cellular;

   Abstract : One of the most distinctive characteristics of the weightless economy is the increasingly important role of the Information and Communication Technology (ICT) sectors, which, according to the OECD (2009), consist of ICT products and media and content products. The ICT sectors have been identified as contributing significantly to the economy through production, measured by the value of the ICT outputs produced and the spillover effects to the other sectors, and the diffusion due to the higher penetration rate of ICT products and services and the impact of the end-users.

6. 4. On Radio Frequency Behavioral Modeling : Measurement Techniques, Devices and Validation Aspects

   Author : Per N. Landin; Peter Händel; Magnus Isaksson; Wendy Van Moer; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik;

   Abstract : Effektförstärkare för radiofrekvensapplikationer utgör fortfarande ett av de största problemen i trådlösa kommunikationssystem. Detta beror på att dessa förstärkare är ickelinjära, har låg energieffektivitet och ger mycket distortioner. Bättre verktyg för att förstå och korrigera dessa beteenden är nödvändiga. READ MORE

7. 5. Backward and Forward Nonlinear Optical Processes in Potassium Titanyl Phosphate

   Author : Kjell Martin Mølster; Fredrik Laurell; Valdas Pasiskevicius; Ulf L. Österberg; Stefano Taccheo; KTH; []

   Abstract : Second-order nonlinear optical processes generate radiation across a broad spectrum, including UV and the far-infrared. In this thesis, new light sources in the near(NIR) and mid infrared (MIR) using three-wave mixing geometries in periodically poled potassium titanyl phosphate (PPKTP) is studied. READ MORE
