Saleem, Muhammad Usman (author)Over the past many years, technology scaling has resulted in a continuous reduction of lateral and vertical dimensions of transistors. The technology scaling, on the one hand, has led to a commensurate performance gain for very-large-scale integration (VLSI) circuits, but on the other hand, has also made such circuits more vulnerable to ionizing...master thesis 2018

Sijbers, Leon (author)Conventional controllers are incapable of controlling a rotor failed quadrotor in high speed flight. In this paper, a fault tolerant controller based on Incremental Nonlinear Dynamic Inversion is proposed to control a quadrotor subjected to the loss of two rotors. A pseudoinverse is used to control the roll and pitch rate to steer the average...master thesis 2018

Vodă, Mircea (author)The continuous shift of various industries towards internet-based services have caused an exponential growth in the amount of data produced over the past few years. On top of this, the increasing need for real-time analytics and the increase in data velocity have made asynchronous, event-driven applications the norm. In this context, the...master thesis 2018

Wan, Y. (author), Keviczky, T. (author)This paper proposes a real-time fault-tolerant estimation approach for combined sensor fault diagnosis and air data reconstruction. Due to simultaneous influence of winds and latent faults on monitored sensors, it is challenging to address the tradeoff between robustness to wind disturbances and sensitivity to sensor faults. As opposed to...journal article 2018

Ferranti, L. (author), Wan, Y. (author), Keviczky, T. (author)This paper focuses on the longitudinal control of an Airbus passenger aircraft in the presence of elevator jamming faults. In particular, in this paper, we address permanent and temporary actuator jamming faults using a novel reconfigurable fault-tolerant predictive control design. Due to their different consequences on the available control...journal article 2018

Conrad, J. (author), Chamberland, C. (author), Breuckmann, N.P. (author), Terhal, B.M. (author)We explore a distance-3 homological CSS quantum code, namely the small stellated dodecahedron code, for dense storage of quantum information and we compare its performance with the distance-3 surface code. The data and ancilla qubits of the small stellated dodecahedron code can be located on the edges respectively vertices of a small...journal article 2018

Verhage, A.A. (author)Technolution B.V. is developing a custom Reduced Instruction Set Computer (RISC)-V based softcore for implementation on a Field Programmable Gate Array (FPGA). Previously, the softcore used the memory residing on the FPGA only, which is very limited in capacity and limits scaling. To solve this problem, a connection is made from the softcore to...master thesis 2016

Heida, W.F. (author)As predicted by Gordon E. Moore in 1975, the number of transistors has doubled every two years over the last decades. This technology scaling led to a higher performance of Integrated Circuits (ICs) like processors, but have also made these devices more susceptible to Single Event Effects (SEEs). SEEs are caused by transistors changing state...master thesis 2016

Lu, P. (author), van Kampen, E. (author), de Visser, C.C. (author), Chu, Q. P. (author)This paper deals with aircraft trajectory control in the presence of model uncertainties and actuator faults. Existing approaches, such as adaptive backstepping and nonlinear dynamic inversion with online model identi_cation, can be applied. However, since there are a number of unknown aerodynamic derivatives, the tuning of parameter update law...journal article 2016

Meun, K. (author)Increased technology scaling not only resulted in a performance increase of the microprocessor, but also led to increasing device vulnerability to external disturbances. Scaling accelerates ageing induced failures of CMOS devices and the average lifetime of electronic devices diminishes. This thesis describes the design and implementation of a...master thesis 2015

Rodrigues, Diego (author), Nazarian, G. (author), Moreira, Álvaro (author), Carro, Luigi (author), Gaydadjiev, G. (author)Software-based methods for the detection of control-flow errors caused by transient fault usually consist in the introduction of protecting instructions both at the beginning and at the end of basic blocks. These methods are conservative in nature, in the sense that they assume that all blocks have the same probability of being the target of...conference paper 2015

Mushtaq, H. (author)Constant reduction in the size of transistors has made it possible to implement many cores on a single die. However, smaller transistors are more susceptible to both temporary and permanent faults. To make such systems more reliable, online fault tolerance techniques can be applied. A common approach for providing fault tolerance is to per- form...doctoral thesis 2015

Chen, C. (author)The aggressive semiconductor technology scaling provides the means for doubling the amount of transistors on a single chip each and every 18 months. To efficiently utilize these vast chip resources, Multi-Processor Systems on Chip (MPSoCs) integrated with a Network-on-Chip (NoC) communication infrastructure have been widely investigated. However...doctoral thesis 2015

Sun, L.G. (author)Consensus exists that many loss-of-control (LOC) in flight accidents caused by severe aircraft damage or system failure could be prevented if flight performance could be recovered using the valid and remaining control authorities. However, the safe maneuverability of a post-failure aircraft will inevitably be reduced due to the malfunction. Non...doctoral thesis 2014

(author)Recently, an incremental type sensor based backstepping (SBB) control approach, based on singular perturbation theory and Tikhonov’s theorem, has been proposed. This Lyapunov function based method uses measurements of control variables and less model knowledge, and it is not susceptible to the model uncertainty caused by fault scenarios. In this...journal article 2013
