2. 1. Entropy, information theory and spatial input-output analysis

   Author : David F. Batten; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Commodity flows; dynamic analysis; entropy; information theory; input-output analysis; probability distributions; regional and interregional modelling;

   Abstract : Interindustry transactions recorded at a macro level are simply summations of commodity shipment decisions taken at a micro level. The resulting statistical problem is to obtain minimally biased estimates of commodity flow distributions at the disaggregated level, given various forms of aggregated information. READ MORE

4. 2. Development and evaluation of methods for control and modelling of multiple-input multiple-output systems

   Author : Fredrik Bengtsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Input-output scaling; Modeling; Fiber length; Tensile Index; Hold-input; Decentralized control; Gramian based measures; Delays; LQG control; TMP; Uncertain data sets; Unreliable communication links; MIMO systems; Control configuration selection; Linear regression; Freeness; Shives; CTMP;

   Abstract : In control, a common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.

5. 3. Multiple-Input Multiple-Output Radio Propagation Channels : Characteristics and Models

   Author : Kai Yu; Björn Ottersten; David Gesbert; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signalbehandling; Signal processing; Signalbehandling;

   Abstract : In recent years, deploying multiple antennas at both transmitter and receiver has appeared as a very promising technology. By exploiting the spatial domain, multiple-input multiple-output (MIMO) systems can support extremely high data rates as long as the environments can provide sufficiently rich scattering. READ MORE

6. 4. On the ICT Economy in the European Countries: Investigating the Contribution of the ICT Sectors Using the Input – Output Model

   Author : Ibrahim Kholilul Rohman; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; input-output; ICT sectors; multiplier.; economic growth; structural change;

   Abstract : Previous studies have been devoted to investigating the future of economic growth and examining the importance of technology and the ICT sectors in accelerating the growth of the economy. These studies are from a macro perspective that emphasizes the role of infrastructure investment, as well as from the firm level analysis, which is mainly related to cost efficiency. READ MORE

7. 5. Adapting Experimental and Monitoring Methods for Continuous Processes under Feedback Control : Challenges, Examples, and Tools

   Author : Francesca Capaci; Erik Vanhatalo; Bjarne Bergquist; Murat Kulahci; Bart De Ketelaere; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Continuous process; Statistical process control; Design of experiments; Engineering process control; Quality improvement; Simulation tools; Kvalitetsteknik och logistik; Quality technology and logistics; Kvalitetsteknik; Quality Technology Management;

   Abstract : Continuous production covers a significant part of today’s industrial manufacturing. Consumer goods purchased on a frequent basis, such as food, drugs, and cosmetics, and capital goods such as iron, chemicals, oil, and ore come through continuous processes. READ MORE
