  2. 1. Uncertainties in Neural Networks : A System Identification Approach

    Author : Magnus Malmström; Fredrik Gustafsson; Isaac Skog; Daniel Axehill; Håkan Hjalmarsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; uncertainty; system identification;

    Abstract : In science, technology, and engineering, creating models of the environment to predict future events has always been a key component. The models could be everything from how the friction of a tire depends on the wheels slip  to how a pathogen is spread throughout society. READ MORE

  4. 2. Identification and synthesis of components for uncertainty propagation

    Author : Mladen Gibanica; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substructuring; uncertainty propagation; uncertainty quantification; surrogate modelling; Monte Carlo method; interface reduction; state-space models; experimental methods; system identification;

    Abstract : For automotive structures, built-up of hundreds of components with property spread, knowing the effects of component variability and its propagation through the system assembly is important in order to mitigate noise and vibration problems. To increase the understanding of how the spread propagates into variability in built-up structures, both experimental and computational aspects are considered in this thesis. READ MORE

  5. 3. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

    Author : Tetiana Bogodorova; Luigi Vanfretti; Konstantin Turitsyn; Francisco Gonzalez-Longatt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

    Abstract : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.

  6. 4. Multivariable Frequency-Domain Identification of Industrial Robots

    Author : Erik Wernholt; Svante Gunnarsson; Jan Swevers; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency-domain identification; industrial robots; nonparametric identification; nonlinear gray-box identification; multivariable systems; closed-loop identification; Automatic control; Reglerteknik;

    Abstract : Industrirobotar är idag en väsentlig del i tillverkningsindustrin där de bland annat används för att minska kostnader, öka produktivitet och kvalitet och ersätta människor i farliga eller slitsamma uppgifter. Höga krav på noggrannhet och snabbhet hos robotens rörelser innebär också höga krav på de matematiska modeller som ligger till grund för robotens styrsystem. READ MORE

  7. 5. 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
