The advancement in IC technology rendering area optimized and fast ICs is primarily attributed to MOSFET scaling theory. The scaling theory sustained the Moore’s law till the channel size reached the nano-meter regime. The issues in MOSFET due to scaling aggregated and resulted in leakage currents and high power dissipation making the transistor unreliable. The research has been done to find a potential replacement for traditional CMOS and to sustain Moore’s law. Many ...

Wave energy reflection, defined as the ratio of offshore to onshore energy flux, R2, of surface gravity waves from a rough rocky shoreline, was investigated from two individual 15-day Acoustic Doppler Current Profiler (ADCP) deployments at Hopkins Marine Station in Monterey Bay, California. The first was deployed in 9 m water depth, located 100 m seaward of the rocky shoreline, and the second was deployed in 2.5 m water depth, located approximately 6 m from the shoreline. The mean R2 for both...

A high performance sense amplifier circuit is used to construct SRAM. The research work aims at using mult iple techniques for power optimization of SRAM cell or complete SRAM chip. Through this paper, we propose a systematic approach for enhancing the performance of SRAM cell by using sense amplifier circuit. The transistor stage number of the proposed design from VDD to GND is reduced for fast low voltage operation. Thus the proposed sense amplifier which is implemented in 180nm CMOS process...

Recently, Cooray introduced a new return stroke model which is capable of predicting the temporal behavior of the return stroke current and the return stroke velocity as a function of the height along the return stroke channel. The authors employed this model to calculate the power and energy dissipation in subsequent return strokes. The results of these calculations are presented here. It was concluded that a large fraction of the total energy available for the dart leader-subsequent stroke...

Wave energy dissipation due to bubble penetration and inferred turbulent penetration from breaking waves in the surf zone is related to the total energy of dissipation. Bubble injection is inferred from void fraction measurements obtained using a 2.3 meter vertical array of eight conductivity sensors extending from the bottom through the water surface. Potential energy and dissipation associated with bubble injection are calculated and compared with total wave dissipation. Total wave...

SPDs manufactured using multi-block MOV technology can indicate the remaining life (in %) of the SPD, thus helping users to plan appropriate replacement and maintenance. However, because the threshold voltage error of parallel-coupled MOV elements is not the same, the rated impulse current of the SPD manufactured by multi-block MOV technology is not equal to the total of the rated impulse current of parallel-coupled MOV elements. The paper presents the method of determining the number of...

A wave height transformation model is developed using surface roller theory. Roller energy production is included in the energy flux balance equation to predict rms wave height for randomly varying, irregular waves over arbitrary bathymetry. The dissipation function is defined using wave roller theory, where the area of the roller is defined from a simple bore analogy. The Rayleigh distribution is used to statistically describe wave heights as waves shoal, break, and dissipate. Model...

A silencer is the passage through which exhaust gases leaves the vehicle after being combusted in the engine. The combustion temperature may reach close to 800ºC. Even though engines are provided with fins to keep it cool with air flow, the exhaust gases are forced out of the chamber while they are still hot. Thus, the silencer also gets heated by the effect of these gases. Hence, there is a need to reduce the effects of harmful heated exhaust gases. Therefore, manufacturers provide chambers...

Evaluation has been done to study heat transfer of a second grade fluid through porous medium under the influence of chemical reaction parameter over a linear impermeable stretching sheet. Similarity transformations are being used to reduce the governing differential equations to ordinary ones which are solved numerically. Effects of different parameters were studied on the fluid flow. The results of stream and heat transfer were shown graphically.

Daily usage of such systems usually produces non-uniform string connected behavior due to partial or total shading. In these conditions, less illuminated cells transform into power receivers, thus producing supplementary losses and local panel heating. This problem, known as mismatch (hot-spot), can reduce the power output of the array and lead to cell degradation through localized heating of individual cells. Such problems can arise simply through the shading of a single cell. For these...

This is not only because they are threatened by climate change, but also because of the important role they play in coastal protection. Some field studies based on Rhizophora mangrove trees have analyzed the force induced by water flow over their roots and the wave dissipation capacity of these trees under tidal regimes and sea waves. Various methods have been used to...

The interaction between the solar wind and the earth's magnetic field creates a large magnetic cavity which is termed the magnetosphere. Energy derived from the solar wind is ultimately dissipated by particle acceleration-precipitation and Joule heating in the magnetosphere-ionosphere. The rate of energy dissipation is highly variable, with peak levels during geomagnetic storms and substorms. The degree to which solar wind and magnetospheric conditions control the energy dissipation processes...
