Power from solar panel is affected by insolation and temperature variation which can be minimized by MPPT system. In this paper to extract maximum power from solar system, perturb and observe technique of MPPT is used. A PV system require proper battery charge controller to balance the power flow from PV system to battery and load such that photovoltaic power is utilized effectively. In this bu...

Since the lifetime of a battery directly impacts the extent and duration of sensor networks, one of the key considerations in the design of sensor networks is the ability to maximize battery lifetime. In this paper, we present (1) a task modeling methodology and (2) a battery-aware real-time task scheduling technique for sensor networks. The task modeling is achieved based on task classificatio...

Lead acid batteries are one of the most commonly used batteries. Monitoring the performance parameters of the battery provides essential data useful for managing the batteries efficiently. This paper proposes a highly accurate and efficient battery monitoring system based on NI LabVIEW. As the calculations are done on computer, this system is faster than micro-controller based systems and provi...

A scroll expander exhaust recovery system with the battery is proposed to improve exhaust recovery efficiency. Based on the exhaust flow, storage pressure and the battery current, expander supply pressure was optimized with the loss model based on the expansion and generator loss. And then the supply pressure controller was designed to track the optimized supply pressure reference using the inp...

Abstract Battery powered embedded system can be considered as a power aware system for a safety critical application. There is a need of saving the battery power for such power aware system so that it can be used more efficiently, particularly in safety critical applications. Present paper describes power optimization procedure using real time scheduling technique having a specific dead line gu...

A solar-wind hybrid power generation system has been presented here. The application based system illustrated in this paper is designed on the basis of the solar and wind data for areas in Northern India. The power generated by the system is intended for domestic use. The most common source of unconventional power in homes is battery based UPS (Uninterrupted power supply) inverter. The UPS inve...

Asymptotic symmetries of theories with gravity in d = 2m+2 spacetime dimensions are reconsidered for m > 1 in light of recent results concerning d = 4 BMS symmetries. Weinberg’s soft graviton theorem in 2m + 2 dimensions is re-expressed as a Ward identity for the gravitational S-matrix. The corresponding asymptotic symmetries are identified with 2m + 2-dimensional supertranslations. An alternat...

Bayesian Belief Networks (BBNs) are a pow­ erful formalism for reasoning under uncer­ tainty but bear some severe limitations: they require a large amount of information be­ fore any reasoning process can start, they have limited contradiction handling capabil­ ities, and their ability to provide explana­ tions for their conclusion is still controversial. There exists a class of reasoning syste...
