ABSTRACT Frequency filters are linear electric circuits that are used in wide area of electronics. They are also the basic building blocks in analogue signal processing. In the last decade, a huge number of active building blocks for analogue signal processing were introduced. However, there is still the need to develop new active elements that […]

ABSTRACT One of the concrete that is becoming famous for its usage nowadays is nanoconcrete and our paper deals with the fact that nanomaterials (like nano-SiO2 & nano-TiO2) when added in optimized proportions to a standard M-40 Grade concrete improves its both fresh and hardened properties (both short term & long term).The results simply corroborated […]

ABSTRACT In ever growing populated world there is no enough space to accommodate the remains of the deceased, so the concept of capsula mundi has been developed by Italian designers Anna Cielli and Raoul Bretzel. Capsula mundi is an organic burial pod made of natural starch plastic in which body of deceased is placed in […]

ABSTRACT Recent technological innovations in electronics and photonics are now enabling THz research to be realized in defence as well as civil sectors. Undoubtedly, microfabricated vacuum electron devices (MVEDs) are capable to fulfil the source requirement. In last couple of years, development of high definition electromagnetic simulation codes, advancement in micro-&-nano fabrication and further characterization […]

ABSTRACT This paper presents the enhancements of PQ parameters such as voltage profile (voltage swell, voltage sag, harmonics, etc.) in Distribution power system by Distributed Generation (DGs) using exhaustive search method. This article is very much useful for researchers, scientific engineers and industrial persons in conjunction with improvements of PQ parameters in distribution systems by […]

ABSTRACT This paper provides a method for computing search direction for constrained nonlinear optimization problems. We discuss some important differences in formulation and solution that arise in quadratic programming based methods for nonlinearly constrained optimization with particular emphasis on the treatment of inequality constraints. Some issues including incompatibility or ill-conditioning of the constraints determination of […]

ABSTRACT This paper deals with the use of an Exhaust Gas Re-circulation (EGR) system on a given Spark Ignition engine for studying the performance and emission characteristics. For various openings of EGR-Valve, experiments are carried out on a set of loads varying from 0 to 15 percent of engine loads at a cruising speed of […]

ABSTRACT This paper presents durability study on self compacting concrete (SCC) with various partial replacements of fly ash, silica fume and combination of both fly ash and silica fume. The slump, V-funnel and L-Box test are carried out on the fresh SCC and in harden concrete compressive strength and split tensile strength values are determined. […]

ABSTRACT Environmental pollution is a big problem, which we all are facing today. Out of which, water pollution is a major problem. Different technologies of advanced oxidation processes are playing important role in solving this problem. Photocatalysis, which is an important part of advanced oxidation process, is considered as a promising technology for waste water […]

ABSTRACT Nowadays microstrip antenna is an important tool for wireless networks. Frequency sensitive antenna by using DGS at 2.39GHz and by using non DGS at 1.96 GHz is being proposed. This study represents microstrip sensor by using a triangular patch antenna using defected ground structure (DGS). It is used for high quality rice measurement. By […]
