ABSTRACT This paper describes the conductometric, potentiometric and antimicrobial investigations on few Cu(II)- thiosemicarbazone complexes. Solution studies on the complexes have also been carried out in different micellar systems at 25°C and data have been compared with ethanol- water mixture. Stability constants have been determined in 60% ethanol by pH metric study. The conductometric studies […]

ABSTRACT This paper aims at design and fabrication of an electromechanical butterfly valve drive system based on a four bar linkage mechanism proposed and developed by the author as a retrofit to conventional combustion system to study and investigate oscillating combustion technology in a crucible furnace. However, there are several challenges to transform by oscillating […]

ABSTRACT A half- mode substrate integrated waveguide (HMSIW)band pass filter is presented. Split ring resonator (SRR) introduced as a series element provides the required bandpass while edge coupled SRRs produce well defined transmission zeros on either side of the passband. The filter is analysed using the LC equivalent circuit and also using the surface current […]

ABSTRACT In this paper, the heat generation and radiation effects on magnetohydrodynamic stagnation-point flow of non-Newtonian Casson fluid flow over a stretching surface through porous medium have been obtained and studied numerically. The governing continuity and momentum equations are converted into a system of   non-linear ordinary differential equations by means of similarity transformation. The resulting […]

ABSTRACT Utilization of multi-renewable energy sources for railway vehicle or train is highly beneficial as an alternative source of energy for its operation. Harvesting energy from various sources such as solar, wind and piezoelectric material is focused in this paper. It is performed employing efficient methodologies found in previous research and concurrent technology with a […]

ABSTRACT The present paper deals with the flow, heat and mass transfer characteristics of magneto hydrodynamics in carreau nanofluid over a permeable stretching sheet with convective boundary conditions in the presence of non-linear thermal radiation and suction\injection effects. The non-linear partial differential equations that govern the flow were transformed to nonlinear ordinary differential equations by […]

ABSTRACT Aggregates play a major role in asphalt mixes. The asphalt mix is made up of approximately 80 – 90% of aggregates. It is thus important to evaluate the effect of aggregate gradation in asphalt mixes. This is due to the escalating rate of South African roads experiencing permanent pavement deformation, particularly in Butterworth (Eastern […]

ABSTRACT In the present work, the ion transport property of Polyvinyl Formal (PVF)-based nanocomposite polymer electrolytes has been investigated upon dispersal of Multiferroic (BFO) nanosized filler particles. With the aim to developed the lithium ion (Li+) conducting nanocomposite polymer electrolytes (NCPEs) Lithium Acetate has been chosen as doping salt. NCPE films were prepared by solution […]

ABSTRACT Seasonal variation, storm water intrusion, ambient temperature etc. are the factors which affects the waste water quality due to which it is difficult to define the quality of wastewater. Wastewater Quality Index (WWQI) is a unit less number ranging within 1 to 100 and able to indicate overall characteristic of wastewater. This index helps […]

ABSTRACT Orthogonal Frequency Division Multiplexing (OFDM) is a gifted scheme to accomplish high data transmission for high speed communication systems. Consequently, it is treated as a strong candidate for forthcoming wireless applications. Nevertheless, the foremost drawback of OFDM signal is high Peak to Average Power Ratio (PAPR), which degrades the performance of the primary resources […]
