  2. 1. Wireless Channel Prediction with Location Uncertainty

    Author : Srikar Muppirisetty; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Spatial wireless channel prediction is important for future wireless networks, andin particular for anticipatory networks to perform proactive resource allocationat different layers of the protocol stack. In this thesis, we study location-awarechannel prediction with uncertainty in location information and understand its utilization to enhance the communication capabilities in wireless networks.

  4. 2. Real-time Locating Systems for indoor applications : the methodological customization approach

    Author : Bartosz Jachimczyk; Wlodek Kulesza; Alfonso Bahillo Martínez; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accuracy and Precision; Angle of Arrival; Fingerprinting Method; Indoor Localization; Indoor Positioning System; Multi-Sensor System; Neural Network; Radio Frequency Identification - RFID; Real Time Locating System; Received Signal Strength; RFID Network Planning; Scene Analysis; Sensors Arrangement; System Customization; Uncertainty; Uncertainty Map; User Driven Design;

    Abstract : Emerging wireless technologies increase the potential and effectiveness of wireless Real-time Locating Systems (RTLSs), which precisely localize the position, and identify things and people in real time. Among many applications, RTLSs are widely used in the industrial sector for indoor logistics and safety applications. READ MORE

  5. 3. Differential-algebraic equations and matrix-valued singular perturbation

    Author : Henrik Tidefelt; Torkel Glad; Ulf Jönsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential-algebraic equations; uncertainty; singular perturbation; state estimation; Automatic control; Reglerteknik;

    Abstract : With the arrival of modern component-based modeling tools for dynamic systems, the differential-algebraic equation form is increasing in popularity as it is general enough to handle the resulting models. However, if uncertainty is allowed in the equations — no matter how small — this thesis stresses that such equations generally become ill-posed. READ MORE

  6. 4. Failure Monitoring and Asset Condition Assessment in Water Supply Systems

    Author : Dalius Misiunas; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; reglerteknik; robotteknik; Automatiska system; Water supply; failure; detection; monitoring; location; bursts; hydraulics; leakage; asset management; condition assessment; pipelines; pipe networks; Automation; control engineering; robotics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

    Abstract : In this thesis, different aspects of failure management in urban water supply systems are discussed. As assets are getting older, the number of pipe failures is increasing and an efficient failure management strategy becomes important. READ MORE

  7. 5. Channel Prediction and Target Tracking for Multi-Agent Systems

    Author : Markus Fröhle; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian processes; multitarget tracking; channel prediction; extended target tracking; Multi-agent system; posterior fusion; location uncertainty;

    Abstract : Mobile moving agents as part of a multi-agent system (MAS) utilize the wireless communication channel to disseminate information and to coordinate between each other. This channel is error-prone and the transmission quality depends on the environment as well as on the configuration of the transmitter and the receiver. READ MORE
