2. 1. Finite Element Modelling of Eddy Current Non-Destructive Evaluation in Probability of Detection Studies

   Author : Anders Rosell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy Current; Model Based Probability of Detection; Probability of Detection; Non-destructive Evaluation; Finite Element Modelling;

   Abstract : The goal of this work has been to evaluate the possibility to use mathematical modelling to characterize the capability and reliability of automated eddy current inspections. The safety in aerospace propulsion is critical. Components that are critical for the operation are therefore designed to withstand material degradation. READ MORE

4. 2. Model-Based Cognitive Radio Strategies

   Author : Kasra Haghighi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spectrum utilization; cognitive radio; censorship; CLAPP; sequential detection;

   Abstract : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates a new class of wireless communication devices known as cognitive radios (CR), which identify vacant spectrum and transmit accordingly. READ MORE

5. 3. On model assisted probability of detection in eddy current evaluation

   Author : Anders Rosell; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Eddy Current; Model Assisted Probability of Detection; Finite Element Modelling; Non-destructive Evaluation;

   Abstract : The goal of this work has been to investigate the possibility to use mathematical modelling to characterize the capability and reliability of automated eddy current (EC) inspections. EC evaluation is one of the most applied methods for non-destructive evaluation (NDE) and is studied within this work. READ MORE

6. 4. Model Based Fault Diagnosis : Methods, Theory, and Automotive Engine Applications

   Author : Mattias Nyberg; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Model based fault diagnosis is to perform fault diagnosis by means of models. An important question is how to use the models to construct a diagnosis system. To develop a general theory for this, useful in real applications, is the topic of the first part of this thesis. READ MORE

7. 5. Detection and Classification in Electrocardiac Signals

   Author : Magnus Åström; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal processing; morphology classification; QRS detection; ischemia; body position changes; electrogram; ECG; electrocardiogram; clustering; classification; Detection; sensing;

   Abstract : Signal processing can be used to condition medical signals to facilitate their interpretation, and to extract clinically important information. The purpose of the present doctoral thesis is to put forward solutions to certain problems encountered in the processing of electrocardiac signals. READ MORE
