Cellular automata (CA) are dynamic systems, successfully used in mathematics, biology, chemistry or physics. The random generated by these systems has also been used in computer science (e.g. games industry) as well as in cryptographic applications (e.g. random number generators). As in the case of more well-known LFSR (Linear Feedback Shift Register), the usefulness of these systems in cryptog...

For any modular spacecraft design that allows for reconfiguration once in orbit, there is a need for an interface that acts as a common connection between the modules. The interface must provide autonomous docking, undocking and communication, in addition to transferring mechanical, electrical and thermal loads through each of the modules. This study focuses on the requirements and design of an...

Pumped storage units bring stability to the electrical power system, so they must remain connected to the grid even during grid faults. In this paper, the authors propose efficient and simple solutions for a doubly fed induction machine pumped storage (DFIMPS) system during grid faults. In case of balanced grid faults, a control reconfiguration strategy is introduced and a hardware solution is ...

This paper presents an alternative approach for dynamic partial self-reconfiguration that enables a Field Programmable Gate Array (FPGA) to reconfigure itself dynamically and partially through a parallel configuration access port (PCAP) under the control of the stand alone PCAP core within the FPGA instead of using an embedded processor. The reconfiguration process is accomplished without an in...

This paper describes the development of genetic algorithms for their application to the reconfiguration problem of radial distribution electrical networks, taking into account the expected occurrence of voltage sags. The reconfiguration is an optimization problem, which is formulated to obtain a radial topology representing the least voltage sags in certain buses. The electric system is represe...

As digital microfluidic biochips become widespread in safety-critical biochemical applications, system dependability emerges as a critical performance parameter. The dynamic reconfigurability inherent in digital microfluidic biochips can be utilized to bypass faulty cells, thereby supporting defect/fault tolerance. In this paper, we propose three different reconfiguration techniques and the cor...

This work proposes an automated reconfiguration system to manage two types of faults in any position inside the solar arrays. The studied are short-circuit ground and open wires string. These were selected because they severely affect power production. By identifying affected panels isolating faulty one, it is possible recover part loss. Among other that can detect locate are: diode short-circu...

Reconfigurable computing architectures allow the adaptation of underlying datapath to algorithm. The granularity elements and data width determines architecture its programming flexibility. Coarse-grained have shown right balance between programmability performance. This paper provides an overview coarse-grained reconfigurable describes Versat, a Coarse-Grained Array (CGRA) with self-generated ...
