Anjam, F. (author)In this dissertation, we propose to combine programmability with reconfigurability by implementing an adaptable programmable VLIW processor in a reconfigurable hardware. The approach allows applications to be developed at high-level (C language level), while at the same time, the processor organization can be adapted to the specific requirements...doctoral thesis 2013

Van den Berg, A.F.C. (author)Fault-tolerant On-Board Computer (OBC) software for the Delfi-n3Xt nanosatellite is needed in order to minimize the risk of failures that may occur while the satellite is operating in space. Failures may be OBC specific, but failures that affect the state of the entire satellite and influence the health of the data bus may occur as well. Some...master thesis 2012

Burlyaev, D. (author)Commercial Off-The-Shelf (COTS) electronic components offer cost-effective solutions for the development of On-Board Computers (OBCs) in the small satellite industry. However, the COTS parts are not originally designed to withstand the space radiation environment. Traditional fault-tolerance practices rely on expensive radiation tests or are...master thesis 2012

Haron, N.Z.B. (author)Emerging nanoelectronic memories such as Resistive Random Access Memories (RRAMs) are possible candidates to replace the conventional memory technologies such as SRAMs, DRAMs and flash memories in future computer systems. Despite their advantages such as enormous storage capacity, low-power per unit device and reduced manufacturing difficulties,...doctoral thesis 2012

Seepers, R.M. (author)In this thesis the design and implementation of a new fault-tolerant architecture is described. The design targets both soft and hard faults by implementing a combination of known fault-tolerance tech niques in an efficient way. The proposed architecture allows a trade-off to be made between performance and fault tolerance by means of...master thesis 2011

Vasilikos, V. (author)In this paper, new heuristic-search methods and algorithms are presented for enabling highly efficient and adaptive, defect-tolerant multiprocessor arrays. We consider systems where a homogeneous multiprocessor array lies on top of reconfigurable interconnects which allow the pipeline stages of the processors to be connected in all possible...master thesis 2011

Beekema, M. (author)Wireless sensor networks are becoming ubiquitous in terrestrial applications. In this thesis we present a platform for wireless on-board spacecraft sensor networks with focus on the sensors that bring high 'added value' to existing space systems while becoming wireless. A novel multi-gateway architecture that uses dual hardware redundancy is...master thesis 2011

Van der Geest, M. (author)High speed fault tolerant permanent magnet machines have strong asynchronous airgap harmonics, making them susceptible to rotor eddy-current losses. These losses can be reduced by using novel high resistivity materials like plastic bonded magnets and carbon fibre reinforced retaining sleeves. This is an entirely new concept, and little knowledge...master thesis 2011

Van Engelen, T. (author), Schuurmans, J. (author), Kanev, S. (author), Dong, J. (author), Verhaegen, M.H.G. (author), Hayashi, Y. (author)Extreme environmental conditions as well as system failure are real-life phenomena. Especially offshore, extreme environmental conditions and system faults are to be dealt with in an effective way. The project Sustainable Control, a new approach to operate wind turbines (Agentschap NL, grant EOSLT02013) pro- vides the concepts for an integrated...conference paper 2011

Grotens, R. (author)Nonlinear Dynamic Inversion (NDI) is a promising method for Fault Tolerant Flight Control. The NDI algorithm cancels out the aircraft dynamics based on a dynamic aircraft model such that the closed loop system behaves linearly. The aircraft model is estimated online, which allows it to accommodate changes in the aircraft configurations and...master thesis 2010

Riemens, D.P. (author)Modern applications demand extremely low power budgets in computer architectures for battery-operated devices. In the particular case of implantable devices —the main focus of this thesis— the system must have a long life span and batteries may not be possible or easy to recharge. In addition to power, chip area is also of major concern in this...master thesis 2010

Borodin, D. (author)In this dissertation we address the overhead reduction of fault tolerance (FT) techniques. Due to technology trends such as decreasing feature sizes and lowering voltage levels, FT is becoming increasingly important in modern computing systems. FT techniques are based on some form of redundancy. It can be space redundancy (additional hardware),...doctoral thesis 2010

Tzilis, S. (author)The ever-shrinking technology features have as a direct consequence the increase of defect density in VLSI chips. Going into the nano-scale era, the fabrication procedures cannot keep improving at the pace of the aforementioned shrinking of technology features. Fault Tolerance emerges as a much cheaper solution and it is imperative in the future...master thesis 2010

Nie, L. (author)Wind energy promises to become an important source of energy in the near future. Penetrating large-scale wind power into power systems presents a lot of challenges to power system operators, generation companies and wind turbine manufactures. In order to design less expensive and more efficient wind turbines, manufacturers have tried a lot of...master thesis 2009

de Koning, A.U. (author), Henriksen, T.K. (author)Probably one of the most challenging problems in fracture mechanics is related to its application to fastener and joints. By nature, not only the quality such as material, manufacturing and mounting processes, of the fasteners are playing a role, but also the stiffness, surface conditions and geometry of the parts are to be considered. Moreover,...report 1996
