Low power design is the industry buzzword these days in present chip design technologies. CMOS technology continues to drive the reduction in switching delay and power while improving area density. However, the transistor miniaturization also introduces many new challenges in Very Large Integrated (VLSI) circuit design, such as sensitivity to process variations, increasing transistor leakage an...

The conventional fixed acoustic sensors leak detection methods have been demonstrated to be very practical for locating leakages in water distribution pipelines. However, these methods demand proper installation of sensors, and therefore cannot be implemented on buried long water distribution pipelines for condition assessment, early leak detection, and the estimation of leak size effect. Due t...

The atmosphere is one of the most important contamination sources in ground-based Cosmic Microwave Background (CMB) observations. In this paper, we study three kinds filters, which are polynomial filter, high-pass and Wiener to investigate their ability for removing atmospheric noise, as well impact on data analysis process through end-to-end simulations CMB experiment. We track performance by ...

A quantum random number generator is implemented in an integrated circuit without the need for complex, bulky and expensive measurement equipment and circuitry. Quantum entropy, chaotic entropy and pseudo-entropy are defined and their combinations mathematically described. Models and design equations are provided for estimating the quantum entropy in the form of shot noise due to sub-threshold ...

OBJECTIVE To determine whether Reiki, a process of transmission of healing energy, can significantly reduce microvascular leakage caused by exposure to excessive noise using an animal model. RATIONALE Reiki is beginning to be used in hospitals to accelerate recovery. Despite many anecdotes describing Reiki's success, few scientific studies are reported and none of those use animals. Animal mo...

We present a novel temperature/leakage sensor, developed for high-speed, low-power, monitoring of processors and complex VLSI chips. The innovative idea is the use of 4T SRAM cells to measure on-chip temperature and leakage.Using the dependence of leakage currents to temperature, we measure varying decay (discharge) times of the 4T cell at different temperatures. Thus, decaying 4T sensors provi...
