Estimation of Absorption Performance of Underwater Anechoic Coating by Multilayer Arrangement of Cylindrical Cavity
Abstract: Rubber coatings with inner cavities are often used as underwater anechoic coatings. What is important in improving the underwater absorption performance is to improve the low frequency absorption performance, while satisfying the broadband absorption performance. Generally the homogenous medium can hardly satisfy the broadband absorption performance. In this paper sound absorption coatings with new arrangement of cavities to satisfy both broadband absorption performance and better low frequency absorption performance is …

The 0^0 Thing Behind Everything
Abstract: Physics is the science of the physique of the universe. The physique of the universe is space. Space is the bottom-most of the universe which cannot be further undermined. Space cannot be seen. Not heard. Not smelt. Not tasted. Not touched or felt. Not known. The moment it is seen, heard, smelt, tasted, felt, known, the question pops up: who is the seeing, hearing, smelling, tasting, feeling, knowing? Consciousness/cognizance is …

The study of Density Functional Theory for dispersion relation in Carbon nanotube with dielectric medium in a coupling mode
Abstract: The author shall study the excitation of Surface Plasmon and Phonon on cylindrical polar semiconducting material. The possibility of their interaction has been discussed with the help of dispersion relation for the dual mode of CNT by using inherent properties of the dielectric interface in dual mode. The phonon dispersion relation of the CNT is calculated by large supercells containing an isolated nanotube, Density functional Theory, and plane wave basis …

A Review of Formation of Oxygen-Related Donors (ODs) and Impurity Concentration in Step-Annealed Czochralski Silicon
Abstract: Czochralski (CZ) silicon being one of the two methods of silicon crystallization, the one that is used commercially for device fabrication, needs to be studied more closely. Hence, the Generation and behaviour of thermal donors (TD) and new donors (ND) as a result of pre-annealing at moderate temperature 480°C of carbon-rich boron-doped (p-type) CZ-silicon has been studied here, as function of annealing time by Hall studies and resistivity measurements in …

An Approach to Simplify Universal Logic Gates Using Majority Function
Abstract: There has always been a continuous urge to reduce power consumption in very large scale integration (VLSI) circuit design. Sometimes reduction in the total number of transistors in a fundamental logic gate helps to enhance power saving. But, there stands a tradeoff in between power, delay and size of the chip. Static and dynamic power gets escalated as the device dimension is scaled down and vice versa. In our approach, …
