Guest Editorial: IEEE Transactions on Emerging Topics in Computing Special Issue on Advanced Command, Control and On-Board Data Processing for Space Avionic Systems
No full textThe papers in this special issue focus on advanced command, control and on-board data processing for space avionic systems. The domain of space avionic systems is changing extremely rapidly, compared to other technical domains in the spacefaring industry, under the pressure of intense competition, the continuous emergence of new markets and players, the need for cost reduction, as well as an increased obsolescence rate of components and processes due to the relative reduction of hi-rel parts market share with respect to booming volumes of consumer electronics. The emergence of "new space" paradigm, with new (mostly private) players taking the risk of compromising with system's dependability in favour of stripped down cost further contributes to this rapidly changing landscape: new opportunities are opening for the space avionic systems
Novel Applications Enabled by Memristors [Guest Editorial]
No full textConstant advances in semiconductor manufacturing have led to the ubiquitous presence of cheap and reliable computing devices in all aspects of our lives. However, further innovation exclusively based on scaling the CMOS technology feature size will not be sufficient in the coming years, as the well-known Moore's law is slowing down. While CMOS is not going to disappear, it will most likely be supported by several other innovative technologies with stronger performance in specific application scenarios. Among various novel technologies, memristors are emerging as promising devices for high-density memory arrays, neuromorphic computing, and, recently, logic and processing in memory. Recent research also revealed memristor sensitivity to gases and other chemicals. All these developments show that memristors have unexplored potential to shift the paradigm for several other applications

A memristor-based sensing and repair system for photovoltaic modules
Full text linkAmong renewable energy sources the sun is certainly one of the easiest to exploit. Solar panels allow generating electrical energy but they generally have low efficiency. It is therefore important to optimize a solar module to maximize its energy production. Faults can have for example a big impact on the amount of energy production, and should be avoided if possible. This goal can be achieved by designing fault tolerant photovoltaic modules. In this paper, we propose a sensing and repair system for photovoltaic modules. The system is based on two key elements: sensing of the photovoltaic cell status through memristors and dynamic reconfiguration of the connections among cells. Using a memristor for sensing allows creating simple yet effective measuring systems that is able to detect the state of each cell of the modules. This information can be read externally or can be used internally by the reconfiguration system. The second key element of our system is indeed a new reconfiguration scheme that allows dynamically changing the connections among cells. This system can be used to reconfigure the connections among cells to maximize energy production, depending on the health state of each solar cell. The same system can be used to substitute redundant cells in the array to compensate faults and to improve energy production. We present a detailed characterization and power analysis of the system, highlighting the improvements in energy production and demonstrating its ability to compensate faults. The solution that we propose is modular and can be extended to arrays of any size. It can also be potentially embedded inside a solar panel, leading to a self-healing device that can improve the energy that is generating
