Nowadays, water and energy resources are becoming scarcer due to the inefficient use of these vital in agricultural irrigation worldwide. The unique solution this problem is application smart technology distribution systems. But most pivot weir installations systems have not access power a remote location from line. This requires developing low-power system for level flow measurement control op...

Dr. Rajit Gadh presented some major challenges and tech­ nologies required to make the US electric grid smart and more efficient, given that energy consumption is rapidly increasing and becoming more expensive. One critical issue is the inflexibility of the current grid system, whose structure assumes a unidirectional flow of power, control, and information. For instance, power generation has a...

This paper presents a new approach for realizing a smart, fault tolerant, controllable and asset efficient power grid through the use of massively-dispersed mass-manufactured communicationsenabled sensor, power-converter and actuator networks. One example is ‘Smart Wires’, implemented using many modules of a Distributed Static Series Compensator (DSSC) device that can be clamped on to existing ...

Java applets run on a Virtual Machine that checks code integrity and correctness before execution using a module called the Bytecode Verifier. Java Card technology allows Java applets to run on smart cards. The large memory requirements of the verification process do not allow the implementation of an embedded Bytecode Verifier in the Java Card Virtual Machine. To address this problem, we propo...

Smart Morphable Surfaces enable switchable and tunable aerodynamic drag reduction of bluff bodies. Their topography, resembling the morphology of golf balls, can be custom-generated through a wrinkling instability on a curved surface. Pneumatic actuation of these patterns results in the control of the drag coefficient of spherical samples by up to a factor of two, over a range of flow conditions.

The smart grid refers to next generation power grids, with multi-directional flows of electricity and information to make a wide distributed network. Through smart grid, the power system becomes smart by communicating, sensing, control and applying intelligence. For ideal system, the smart grid technologies are more compatible to permits many functions which can optimize with the combination of...

while weeds in sugar beet farming reduce crop yield and quality, they also lead to higher labor and material losses. in recent years, in order to eliminate or reduce the damage caused by weeds in sugar beet farming, weed control has gained importance. to this end, various studies have been conducted on robotic weed control by detecting weeds using image processing algorithms and hoeing or spray...

Electric utilities are finding it increasingly necessary to better monitor, analyze and control their distribution systems. Planning and operation of the grid is increasing in complexity on 0 one hand but subject to ever more binding constraints on the other. Real-time analysis is being seen as necessary to achieve acceptable operational efficiencies and quality of service. Real-time analysis i...

Smart grid is a new approach for electric power grid that uses information and communications technology to control the electric power grid. Smart grid provides real-time control of the electric power grid, controlling the direction of power flow or time of the flow. Control devices are installed on the power lines of the electric power grid to implement smart grid. The number of the control de...

Smart microgrids offer a new challenging domain for power theories and compensation techniques, because they include a variety of intermittent power sources, which can have dynamic impact on power flow, voltage regulation, and distribution losses. When operating in the islanded mode, low-voltage smart microgrids can also exhibit considerable variation of amplitude and frequency of the voltage s...
