In the present scenario of a huge energy demand, dependency on fossil fuels only, certainly creates crisis in future especially for developing country. Although renewable resources of energy like solar energy is being ...
Wastewater from industries contains a considerable amount of chemicals and is characterized by high biological oxygen demand (BOD), heavy metals, intense color and are thus toxic to the environment. White-rot fungi such ...
Our inspiration comes from Nell (Never Ending Language Learning), a computer program running at Carnegie Mellon University to extract structured information from unstructured web pages. We consider the problem of semi-supervised ...
The main objective of the current work was to investigate the transformation mechanism in quasicrystals during mechanical alloying/milling. The quasicrystalline phases have been synthesized by melting the individual elements ...
A nano τ3 vacancy-ordered phase in the Al-Cu-Ni alloy system has been synthesized with a composition close to Al70Cu 15Ni15 by mechanical alloying a mixture of elemental powder in a high-energy ball mill by varying milling ...
Mott-Hubbard anti-ferromagnetic insulator, NiO shows p-type semiconducting behaviour due to vacancy at Ni2+ site in its bunsenite structure. We report the modification of structural and magnetic order in NiO on Fe doping. ...
The intent of performance-based earthquake engineering is to provide methods for designing, constructing and maintaining buildings, such that they are capable of providing predictable performance when affected by earthquakes. ...
In the present study, a low-temperature synthesis of (Cu,Fe)Al 2O4 and (Cu,Cr,Fe)Al2O4 spinels from the quasicrystalline phases was investigated with the variation of process parameters during milling and annealing. The ...
Most of the real-world black-box optimization problems are associated with multiple non-linear as well as non-convex constraints, making them difficult to solve. In this work, we introduce a variant of the Covariance Matrix ...
Newman Penrose (NP) formalism is a new approach to general relativity was presented. In various geometrical groups are estimate on a chosen null tetrad basis for tetrad formalism. This approach widely used in analytical ...

The analysis of a Ka-band gyrotron Travelling Wave Tube (gyro-TWT) amplifier using a uniform cylindrical waveguide as its interaction circuit has been presented for the TE01 mode of operation a self-consistent nonlinear ...
The structural and mechanical stability of quasicrystals are important issues due to their potential for possible applications at high temperatures and stresses. The aim of the present work is, therefore, to review the ...
In the present investigation, we have studied leaching on polygrain Al-based quasicrystalline (i-Al63Cu25Fe12) as well as crystalline (B2 phase; Al55Cu30Fe15) alloy surfaces using a 10 mole NaOH solution. The surface was ...

Aluminium alloy 2014 is an important age hardening alloy for aerospace industries. Effect of ultrasonic shot peening (USSP) in peak aged condition of this alloy was studied on its surface microstructure, tensile properties ...
Today, most of the electricity generated comes from fossil fuels (coal, oil, and natural gas). These fossil fuels have finite reserves and will run out in the future. The negative effect of these fossil fuels is that they ...
This paper investigates the feasibility of using Lauric acid as a phase change material (PCM) to store excess solar energy and release it when the energy availability is inadequate or not available for solar drying process. ...
