A glitch compensation methodology is proposed in this paper which involves in reducing the undesired switching of combinational circuits in order to save dynamic power. The proposed methodology can be seamlessly integrated to existing physical design flow. A glitch is an undesired transition that occurs before intended value in digital circuits. A glitch(More)
Pravdo et al (1997) claimed that the phase resolved x-ray spectrum in Crab pulsar (PSR B0531+21) shows a spectral hardening at the leading edge of the first peak of its integrated profile (IP); this was a new and unexpected result. This article reanalyzes their data, as well as some other related data, and argues that the spectrum is as likely to be(More)
The instability in one of the components of the radio integrated profile (IP) of the millisecond pulsar PSR J0437−4715 is correlated with the occurrence of the spiky emission in that component. It is speculated that the instability in other components is also due to the spiky emission. This might have important implications for interpreting the individual(More)
Deshpande & Rankin (1999, 2001) claim that the frequency of the very narrow feature, in the spectrum of radio flux variations of PSR B0943+10, is an alias of its actual value. For this, they need to interpret the narrow feature as a very stable pattern of drifting sub pulses on the polar cap of this pulsar, within the framework of the Ruderman & Sutherland(More)
Wireless sensor networks (WSNs) have been considered as a promising method for reliably monitoring both civil and military environments under hazardous or dangerous conditions. Due to such environments ,the power supplies for sensors in the network are not usually rechargeable or replaceable. Therefore, the energy efficiency is critical for the lifetime and(More)
