2. 21. Estimation of Thrust and Health Parameters for Jet Engines

   Author : Mattias Henriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thrust estimation; Kalman filtering; Gas turbine performance estimation; Reduced order observers; Gas path analysis;

   Abstract : An advanced turbofan engine control system would benefit from an accurate thrust and engine performance estimate. Unfortunately, there is to date no reliable in-flight thrust measurement sensors available. READ MORE

4. 22. Implementation, identification, and adaptation of Preisach like hysteresis models

   Author : Marcus Hedegärd; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hysteresis modeling; adaptive hysteresis compensation.; generalized Prandtl-Ishlinskii model; Preisach model; magnetoelastic sensor;

   Abstract : The extended generalized Prandtl-Ishlinskii model (XGPI) of hysteresis has a wide applicability, partly because of its capability of modelling highly asymmetric hystereses. For a given parameterization, it is typically identified using non-linear least squares optimization with concomitant problems of convergence, dependence on initial parameter guess and local minima.

5. 23. Distributed Detection and Its Applications with Energy Harvesting Wireless Networks

   Author : Sinchan Biswas; Subhrakanti Dey; Steffi Knorn; Anders Ahlen; Pierluigi Salvo Rossi; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting; Wireless Sensor Networks; Distributed Detection; Cognitive Radio Networks; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

   Abstract : With the advent and widespread applications of high data-rate wireless services and devices, two of the fundamental resources in wireless communication have become extremely important and are scarce. These two resources are bandwidth and energy respectively. READ MORE

6. 24. A Functional Approach to Hardware Software Co-Design

   Author : Markus Aronsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; domain specific languages; functional programming; signal processing; code generation;

   Abstract : Developing software for embedded systems presents quite the challenge---not only do these systems demand good knowledge of the hardware they run on, but their limited resources also make it difficult to achieve efficiency. For embedded systems with different kinds of processing elements, the challenge is even greater; the presence of heterogeneous elements both raises all of the issues associated with homogeneous systems, and may also cause non-uniform system development and capability.

7. 25. Inverse modelling of GNSS multipath signals

   Author : Joakim Strandberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; GNSS; reflectometry; sea ice; sea level;

   Abstract : Measuring the world around us is necessary to observe and understand the changes that occur in our environment. A widely distributed network of measurement stations can help us to understand ongoing and predict future climate change. READ MORE
