2. 1. Autonomous cloud resource provisioning : accounting, allocation, and performance control

   Author : Ewnetu Bayuh Lakew; Erik Elmroth; Hiaohui (Helen) Gu; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cloud computing; distributed infrastructure; monitoring; accounting; performance modeling; service differentiation; business data processing; administrativ databehandling;

   Abstract : The emergence of large-scale Internet services coupled with the evolution of computing technologies such as distributed systems, parallel computing, utility computing, grid, and virtualization has fueled a movement toward a new resource provisioning paradigm called cloud computing. The main appeal of cloud computing lies in its ability to provide a shared pool of infinitely scalable computing resources for cloud services, which can be quickly provisioned and released on-demand with minimal effort.

4. 2. Aperiodic Array Synthesis for Telecommunications

   Author : Carlo Bencivenni; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PtP; mutual coupling; SATCOM; compressive sensing; aperiodic array; density taper; MU-MIMO; maximally sparse array; LoS-MIMO;

   Abstract : Arrays of antennas offer important advantages over single-element antennas and are thus a key part of most advanced communication systems. The majority of current arrays are based on a classical regular layout, which offer simple design criteria despite some limitations. READ MORE

5. 3. Energy Modelling and Fairness for Efficient Mobile Communication

   Author : Ekhiotz Jon Vergara Alonso; Simin Nadjm-Tehrani; Mikael Asplund; Andrew Rice; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; mobile communication; mobile applications; energy accounting; energy-efficient software; cooperative game theory;

   Abstract : Energy consumption and its management have been clearly identified as a challenge in computing and communication system design, where energy economy is obviously of paramount importance for battery powered devices. This thesis addresses the energy efficiency of mobile communication at the user end in the context of cellular networks. READ MORE

6. 4. Microwave measurement techniques for industrial process monitoring and quality control

   Author : Johan Nohlert; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; powder; matched filter; fluidised bed; parameter estimation; cavity resonator; signal detection; finite element method; microwave measurement;

   Abstract : Process monitoring and quality control by sensor measurements are essential for the automatisation and optimisation of many industrial manufacturing processes. This thesis is concerned with microwave sensing, which is a measurement modality with potential to improve the in-line sensing capabilities in several industries. READ MORE

7. 5. High Spectral Efficiency Fiber-Optic Transmission Systems Using Pilot Tones

   Author : Mikael Mazur; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coherent Optical Communications; Analog Optical Signal Processing;

   Abstract : Modern fiber-optic communication systems combine state-of-the-art components with powerful digital signal processing (DSP) to maximize the system spectral efficiency (SE). Systems rely on wavelength-division multiplexing, including superchannel transmission, to enable transmission over the available bandwidth which reaches about 10 THz when accounting for the so-called C and L bands.
