ABSTRACT.
The ultrasonic testing of concrete structures has posed many problems. Conventional methods such as pulse echo and pitch catch are of limited use due to its composition, aggregates will cause scattering and multiple reflections. Alternative ultrasonic methods have been recently investigated that examine the shape of the waveform as it traverses through a complex material, the idea being not to located a single defect but to determine the overall mechanical properties within a certain region. In damaged materials, particularly ones ....etc

1. INTRODUCTION
Industrial plants (e.g. paper factories) has put continuous pressure on the
advanced process automation. The uninterrupted electricity distribution is one
basic requirement for the process. A disturbance in electricity supply causing a
shutdown of the process may cost huge amount of money. Thus the intelligent
management of electricity distribution including, for example, preventive
condition monitoring and on-line reliability management has a great importance.
In industrial processes a huge amo ....etc

Abstract
Biogas technology, besides supplying
energy and manure, provides an excellent opportunity
for mitigation of greenhouse gas (GHG)
emission and reducing global warming through
substituting firewood for cooking, kerosene for
lighting and cooking and chemical fertilizers. A
study was undertaken to calculate (1) global
warming mitigation potential (GMP) and thereby
earning carbon credit of a family size biogas plant
in India, (2) GMP of the existing and target biogas
plants in the country and (3) atmos ....etc

ABSTRACT

This paper focuses on a shunt active filter based on the detection of harmonic voltages at the point of installation. The objective of the active filter is to attenuate harmonic propagation resulting from series/parallel resonance between capacitors for power factor correction and line inductors in a power distribution line. The active filter acts as a low resistor to the external circuit for harmonic frequencies, and it is installed on the end bus of the power distribution line, just like a 50 O terminator installed on the end ter ....etc
