in this paper, a new structure possessing the advantages of low-power consumption, less hardware and high-speed is proposed for fuzzy controller. the maximum output delay for general fuzzy logic controllers (flc) is about 86 ns corresponding to 11.63 mflips (fuzzy logic inference per second) while this amount of the delay in the designed fuzzy controller becomes 52ns that corresponds to 19.23 m...

Masdar City in the United Arab Emirates is designed to be the first modern city powered solely by renewable energy. However, the stochastic nature of renewable energy generators has remained a major challenge in their sole and largescale deployment. Traditional approaches couple large-scale storage systems to renewable generators to mitigate the intermittency in their supply pattern. More recen...

The presented paper gives an overview of basic principles and recent trends in power management electronics for thermoelectric energy harvesting. Energy harvesting systems are a modern way how to feed the autonomous devices on-site using ambient energy. The ambient energy in the case of thermoelectric generators is represented by temperature gradients. Different temperatures are applied to the ...

“The idea is to generate electric energy from the mechanical movements of living beings”. When living beings make mechanical movements, they spend their energy some of which is converted to work. The wasted energy can be converted to electrical energy with the help of nano-generators. The nano generators have a piezo electric crystal (say ZnO) which is made up of nanoparticles. These piezo elec...

Within his publication we demonstrate an energy-autonomous wireless temperature monitoring system that is powered by piezoelectric energy harvesting. An air compressor pump has been chosen as a representative target system. Two different types of piezoelectric generators, cantilever beam with a maximum power output of 37 μW and an impact-type membrane generator with a power output of 120 μW, we...

Monitoring environmental parameters in data centers is gathering nowadays increasing attention from industry, due to the need of high energy efficiency of cloud services. We present the design and the characterization of an energy neutral embedded wireless system, prototyped to monitor perpetually environmental parameters in servers and racks. It is powered by an energy harvesting module based ...

Many isolated small power systems are powered by diesel generators, which results in greater operating costs than interconnected large grids. It is therefore desirable to integrate renewable energy sources such as wind power into these small grids. However, due to the fluctuating power generation from renewable energy sources, frequency deviations of power systems become problematic. Distribute...

Engineering As of 2008 1.46 billion people, or 22 percent of the World's population, were without electricity. Many of these people live in remote areas where decentralized generation is the only method of electrification. Most mini-grids are powered by diesel generators, but new hybrid power systems are becoming a reliable method to incorporate renewable energy while also reducing total system...

Introducing methods for instant tough bonding between hydrogels and antagonistic materials-from soft to hard-allows us to demonstrate elastic yet tough biomimetic devices and machines with a high level of complexity. Tough hydrogels strongly attach, within seconds, to plastics, elastomers, leather, bone, and metals, reaching unprecedented interfacial toughness exceeding 2000 J/m2. Healing of se...

Both pulsatile (AC) and continuous (DC) electrical fields have been reported to increase growth or healing or otherwise modify the structure of various tissues, including nerves, bones and skin. Systematic application of these techniques in both animal research and clinical treatment has been hampered by the limitations of currently available technology. We describe a new modular approach in wh...
