Modeling of a nonlinear hydropower system and control with different types of PID controllers is discussed in this paper. Earlier first order model of hydro power plant discussed by severally but with sudden load changes and nonlinearities of hydropower system affect the system. Nonlinearities of hydropower system are discussed in this paper. External disturbances due to load changes are introduced...
The performance of proposed surface plasmon resonance based methane gas sensor based on Kretschmann configuration in infrared (IR) is discussed. In this structure, calcium fluoride (CaF2) substrate is considered with gold (Au) layer deposited on its base and methane gas is used as a sensing layer. Performance of sensor is analysed in terms of sensitivity and figure of merit (FOM) with various metal...
The microstrip patch antenna modiflcations have been being conducted over approximately four decades by different simulation tools. In this paper, an elliptical microstrip antenna (EMSA) is considered as a reference one and the introduction of an F-cut on it has brought improvements in the various parameters in both the operating bands with the centre frequencies of 3.6 GHz (S-Band) and 5.3 GHz (C-Band)...
In this work the authors proposed a multiplier circuit which is one of the important hardware block in most of the digital and high performance systems such as ALU in the microprocessors and controllers. Multiplication is one of the most time consuming operation as a number of bit increase multiplication become cumbersome in the processors. The multiplier architecture proposed in this paper is based...
Restructuring and competition are being introduced into the electric power industry as deregulation takes place throughout the world. In the competitive electricity markets, the electricity producers come across fundamental problems of bidding into the market to maximize their expected profits. Generally bi-level bidding strategy is used to maximize the profit and to minimize the market clearing function...
In this paper, the Vivaldi Antenna which is meant for UWB Communication's has been initiated. The main motives behind this design is to achieve higher gain throughout the range of 3.1 GHz to 10.6 GHz as a result of which it fulfills the criteria's of UWB antenna for applications in wireless communication. In case of these developments, the author has used Rogers RT 5870 substrate with an epsilon value...

The design o f antenna has been made to ensure the compact size of the designed antenna and operating bandwidth of 1.007 GHz (7.281 GHz-8...
In this paper, the design and performance analysis of dual circular stacked microstrip patch antenna for S-band applications has been proposed. In the proposed antenna design, the substrate of material FR 4 having dielectric constant 4.4 have been used. The ground, patch and feedline are of copper material. The proposed antenna has two circular stackings on the patch and the antenna has impedance...
Recent grid code particularly established for high penetration of renewable power generation in the power system demand the network support similar to conventional generator in steady state and dynamic operations. voltage instability is one of the major concerns with huge amount of wind power penetration in the existing power system which is due to insufficient amount of reactive power. Modern wind...
In this paper, a textile terahertz reduced ground microstrip patch antenna for detection of trinitrotoluene (TNT) has been proposed. The proposed antenna is employing black denim as substrate having dielectric constant of εr = 1.6. The design and simulation of antenna has been carried out using CS T Microwave Studio 2014. The ground and patch of the proposed antenna has been designed using copper...
This paper proposes design of a weight measurement system capable of measuring weight in the range of micrograms to milligrams. The configuration of the system resembles with a conventional straw balance. Unlike straw balance the proposed system employs a force overcome technique. It does not employ any spring as that in case of other types of electromagnetic balance and any vibrating element present...
This paper addresses adaptive fuzzy logic controller for load frequency control of a multi-source two area power system with different power generation sources viz hydro gas & thermal power plant. Expert knowledge is required for conventional fuzzy logic control in developing parameters. Whereas in this method rules are tuned online by adaptation algorithm according to operating condition. The...
In this paper, a compact air gap microstrip patch antenna with high gain and directivity for satellite and mobile communication has been proposed. The proposed antenna has been designed using Flame Retardant 4 (FR4) as substrate having dielectric constant εr of 4.4 sandwiched in between patch and ground plane made up of copper. The power from coaxial connector is fed to the designed antenna via microstrip...
This paper demonstrates the design and performance analysis of the star shaped microstrip patch antenna. The proposed antenna design employs substrate of FR4 material having thickness and dielectric constant of 1.6 mm and 4.4 respectively.

Among the renewable energy sources, the energy obtained by the photovoltaic effects is to be considered the most sustainable energy source using Photovoltaic (PV) cell because of its affluence and pervasiveness. Basically the use of PV cells in solar energy generation are widely used because they directly convert the sun's light into electrical energy. The main drawback is that the solar radiation...
Current health care organization requires manual caretakers and their heavy duties become a social problem in the modern world which is an extremely time-consuming job. We are proposing a system in which remote drip infusion monitoring and control system has been developed for hospitals. The system contains numerous Infusion monitoring devices, control system, and a central monitor. The infusion monitoring...
