2. 1. Gaussian Processes for Positioning Using Radio Signal Strength Measurements

   Author : Yuxin Zhao; Fredrik Gunnarsson; Fredrik Gustafsson; Carsten Fritsche; Simo Särkkä; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian process; positioning; radio signals;

   Abstract : Estimation of unknown parameters is considered as one of the major research areas in statistical signal processing. In the most recent decades, approaches in estimation theory have become more and more attractive in practical applications. READ MORE

4. 2. Resource-Constrained Embedded Control and Computing Systems

   Author : Dan Henriksson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; reglerteknik; kontroll; Automation; robotics; control engineering; Automatiska system; numerisk analys; system; Datalogi; control; numerical analysis; systems; Computer science; Server control; Simulation tools; Feedback scheduling; Real-time control systems; Resource constraints;

   Abstract : This thesis deals with methods for handling resource constraints in embedded control systems and real-time computing systems. By dynamic feedback-based resource scheduling it is possible to achieve adaptability andincreased performance for these systems. READ MORE

5. 3. Estimation of Nonlinear Dynamic Systems : Theory and Applications

   Author : Thomas B. Schön; Fredrik Gustafsson; Simon Godsill; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; Automatic control; Reglerteknik;

   Abstract : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. READ MORE

6. 4. Radio Resource Management in Bunched Personal Communication Systems

   Author : Miguel Berg; KTH; []
   Keywords : radio resource management; dynamic channel allocation; power control; interference avoidance; link-gain matrix; path-loss measurements; microcells; mobile positioning; trilateration;

   Abstract : The traditional way of increasing capacity in a wirelesscommunication system has been cell splitting and fixedchannel-allocation based on prediction tools. However, theplanning complexity increases rapidly with the number of cellsand the method is not suitable for the large temporal andspatial traffic variations expected in the future. READ MORE

7. 5. Neuromechanical basis of airflow-dependent antennal positioning in hawkmoths

   Author : Dinesh Natesan; Örjan Ekeberg; Sanjay P. Sane; Volker Dürr; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; insect antennae; antennal positioning; antennal hair plates; Böhm’s bristles; Johnston’s organs; control theory; hierarchical neural circuits; tuneable feedback loop; flexible reflexes; Computer Science; Datalogi;

   Abstract : Fast behaviors, seen in varied life forms, are often considered to be stereotypic and reflexive and the control neural circuits to be hard-wired. However, many such reflexes have been shown to respond in a context-dependent manner. READ MORE
