1. 6. Fully Printed Chipless RFID Tags towards Item-Level Tracking Applications

   Författare :Botao Shao; Lirong Zheng; Smail Tedjini; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chipless RFID tag; configurability; inkjet printing; time domain; frequency domain; paper substrate; tag antenna; linearly tapering; LC resonator;

   Sammanfattning : An ID generating circuit is unquestionably the core of a chipless RFID tag. For convenience of printing process and cost consideration, the circuit should be kept as simple as possible. LÄS MER

3. 7. Tools for Autonomous Process Control

   Författare :Anders Wallén; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential control; software architectures; fast set point response; spectral estimation; frequency domain identification; relay feedback; non-linear system identification; Autonomous Control; Process Control; Grafcet; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Sammanfattning : There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor.

4. 8. Model Reduction and Parameter Estimation for Diffusion Systems

   Författare :Bharath Bhikkaji; Torsten Söderström; Claes Breitholtz; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion system; Partial differential equations PDEs ; Model reduction; PDE solvers; Finite difference approximation; Chebyshev polynomials; System identification; Parameter estimation; Recursive estimation; Frequency domain estimation; Signal processing; Signalbehandling;

   Sammanfattning : Diffusion is a phenomenon in which particles move from regions of higher density to regions of lower density. Many physical systems, in fields as diverse as plant biology and finance, are known to involve diffusion phenomena. Typically, diffusion systems are modeled by partial differential equations (PDEs), which include certain parameters. LÄS MER

5. 9. Closed-loop Identification : Methods, Theory, and Applications

   Författare :Urban Forssell; Lennart Ljung; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : System identification deals with constructing mathematical models of dynamical systems from measured data. Such models have important applications in many technical and nontechnical areas, such as diagnosis, simulation, prediction, and control. LÄS MER

7. 10. Bayesian Modeling of Directional Data with Acoustic and Other Applications

   Författare :Jalil Taghia; Arne Leijon; W. Bastiaan Kleijn; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Directional statistics; directional distributions; axial distributions; von Mises-Fisher distribution; complex Watson distribution; complex Bingham distribution; Bayesian inference; probabilistic modeling; variational inference; two-dimensional hidden Markov models; Markov chain; blind source separation; frequency domain BSS; underdetermined BSS; online BSS; Bayesian recursive; gene expression data; gene-microarray data; line spectral frequency; speaker identification. ii;

   Sammanfattning : A direction is defined here as a multi-dimensional unit vector. Such unitvectors form directional data. Closely related to directional data are axialdata for which each direction is equivalent to the opposite direction.Directional data and axial data arise in various fields of science. LÄS MER
