Due to the development of new grid codes, power converters’ output signal harmonic control is currently becoming extremely important in mediumand high-power applications. By taking this new scenario into account, a new method to generate switching three-level pulsewidth-modulation (PWM) patterns to meet specific grid codes is presented. The proposed method,(More)
In this paper we present a novel field programmable mixedsignal integrated device consisting of a Field Programmable Gate Array (FPGA), a set of programmable and interconnectable analog cells, and a microprocessor core. This processor can run general purpose user programs, handle the dynamic reconfiguration of the programmable blocks and probe in real time(More)
In critical digital designs such as aerospace or safety equipment, radiation-induced upset events (single-event effects or SEEs) can produce adverse effects, and therefore, the ability to compare the sensitivity of various proposed solutions is desirable. As custom-hardened microprocessor solutions can be very costly, the reliability of various commercial(More)
Mission-critical applications such as space or avionics increasingly demand high fault tolerance capabilities of their electronic systems. Among the fault tolerance characteristics, the performance and costs of an electronic system remain the leader factors in the space and avionics market. In particular, when considering SRAM-based FPGAs, specific(More)
Childhood obesity is a major worldwide health problem. Intervention programs to ameliorate the rate of obesity have been designed and implemented; yet the epidemic has no end near in sight. AMP-activated protein kinase (AMPK) has become one of the most important key elements in energy control, appetite regulation, myogenesis, adipocyte differentiation, and(More)
Multilevel converters have received increased interest recently as a result of their ability to generate high quality output waveforms with a low switching frequency. This makes them very attractive for high power applications. A Cascaded HBridge converter is a multilevel topology which is formed from the series connection of H-Bridge cells. Optimized pulse(More)
The protection of processor-based systems to mitigate the harmful effect of transient faults (soft errors) is gaining importance as technology shrinks. At the same time, for large segments of embedded markets, parameters like cost and performance continue to be as important as reliability. This paper presents a compiler-based methodology for facilitating(More)
Today, many companies are facing the problem of component obsolescence in embedded systems. The incredibly fast growth rate of semiconductor companies is reducing dramatically the time components are available on the market. Twenty years ago, components remained on the market for 5 to 10 years; nowadays, they disappear from the market in less than two(More)
New trends in technology require efficient control and processing platforms based on connected software-hardware subsystems. Due to their complexity and size, algorithms implemented on these platforms are difficult to test and verify. When these types of solution are being designed, it is necessary to provide information of the internal values of registers(More)
It has been suggested that children prenatally exposed to methimazole may present some features in common but the phenotype remains to be defined. The reported facial features include upward slanted palpebral fissures, arched flared eyebrows and small nose with a broad bridge. Choanal atresia and other anomalies like esophageal atresia and aplasia cutis(More)
