(author), Verweij, M.D. (author), de Jong, N. (author), Pertijs, M.A.P. (author)This paper presents an ultrasound transceiver application-specific integrated circuit (ASIC) designed for 3-D ultrasonic imaging of the carotid artery. This application calls for an array of thousands of ultrasonic transducer elements, far exceeding the number of channels of conventional imaging systems. The 3.6 x 6.8 mm² ASIC...journal article 2018

Shekhar, A. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)The role of MVDC links for distribution network expansion is important. The distribution network operators (DNOs) can maximize the power transfer capacity of existing grid infrastructure during (n-1] contingencies using reconfigurable parallel ac-dc architecture. In addition this concept involves a range of efficiency, reliability and...conference paper 2018

Shekhar, A. (author), Kontos, E. (author), Ramirez Elizondo, L.M. (author), Bauer, P. (author)A practical issue faced by today's ac grid is the rapidly growing power demand on its aging infrastructure. One possibility to maximize the capacity of the existing infrastructure is to refurbish the ac links to operate under dc conditions using modular multilevel converters. In this paper, the idea is applied to restructure an actual medium...conference paper 2018

de Groot, T.H. (author), Krasnov, O.A. (author), Yarovoy, Alexander (author)Modern sensors, such as multifunctional radars, comprise many settings and the number of controllable settings is increasing due to technological advance. Although having many settings allows many capabilities, it simultaneously requires an automatic manager to control them. This paper proposes mission-driven resource management to control...journal article 2018

Shekhar, A. (author), Ramirez Elizondo, L.M. (author), Feng, Xianyong (author), Kontos, E. (author), Bauer, P. (author)While the scientific community recognizes the benefits of DC power transfer, the distribution network operators point out the practical and economic constraints in refurbishing the existing AC network at a medium-voltage level. Some apprehensions like reliability, cost of ownership, and safety in adopting a universal DC distribution may merit...journal article 2018

Haider, S.N. (author), Yarovoy, Alexander (author), Roederer, A.G. (author)A frequency reconfigurable phased array element is presented. The operational band of the single port L/S-band antenna can be selected by modifying the element apertures with p-I-n diode switches. The antenna element satisfies strict requirements on its frequency band separation (2.2:1), size, feeding structure and control lines to be...journal article 2017

Yu, Minjing (author), Liu, Yong-Jin (author), Wang, C.C. (author)Self-reconfigurable modular robots (SRRobot) that can change their shape and function in different environments according to different tasks have caught a lot of attention recently. Most existing prototypes use professional electronic components with relatively expensive cost and high barrier of fabrication. In this paper, we present a low-cost...conference paper 2017

Homulle, Harald (author), Visser, S.M.C. (author), Charbon-Iwasaki-Charbon, E. (author)We propose an analog-to-digital converter (ADC) architecture, implemented in an FPGA, that is fully reconfigurable and easy to calibrate. This approach allows to alter the design, according to the system requirements, with simple modifications in the firmware. Therefore it can be used in a wide range of operating conditions, including a harsh...journal article 2016

Robertson, P.D. (author)Reconfigurable mechanisms are a relatively recent contribution to the field of mechanism design and authors have only just been producing real-life applications of these mechanisms. This paper builds on the application of two categories of reconfigurable mechanisms by applying a generalised static balancing theory suggested in a previous review...master thesis 2016

Van Straten, J. (author)This thesis describes the design and implementation of a VLIW processor and associated caches based on the ρ-VEX concept. An ρ-VEX processor must be dynamically (runtime) reconfigurable to behave as a single large processor, two medium-sized processors, or four small processors. This allows a scheduler to optimize for energy and/or performance...student report 2016

Johansen, J. (author)The ?-VEX is a run-time reconfigurable Very Long Instruction Word (VLIW) processor. This unique processor allows separation of its issue lanes to form independently operating processing cores. Switching between these configuration during run-time allows optimizing the platform for the task(s) it is performing. Porting an Operating System (OS) to...master thesis 2016

Jaspers, M.J. (author)With the advent of Next Generation Sequencing (NGS), the cost of sequencing human DNA has decreased significantly over the past decade. This decrease in cost has attracted a great deal of attention from medical research and is now transitioning to clinical practice. Precision medicine, tailored to a persons's genetic profile, is becoming a...master thesis 2015

Haider, S.N. (author)Sensors such as phased array radars play a crucial role in public safety. They are unavoidable for surveillance, threat identification and post-disaster management. However, different scenarios impose immensely diverse requirements for these systems. Phased array systems occupy a large space. In addition, if different antenna systems are needed...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
