Abstract Today, piezoelectric sensors are widely used and very well known for industry. These sensors are characterized by their linearity and broad response frequency range. The main piezoelectric materials that are used for sensoric applications are single crystal quartz and PZT ceramics. This paper tries to clarify the advantages and disadvantages of these materials, especially…
Abstract This paper reports a quasi 3D numerical simulation in a curved river reach of the Mississippi River near The Rock Lake, USA, aiming to develop a numerical tool for modeling turbulent flows and pollutant transport in complex natural waters. The recently built depth-averaged two-equation turbulence model, together with and models, were used to close…
Abstract Soliton is the only stable shape of the pulsesatfiber with dispersion and nonlinear features. This feature cause that pulse width is between 1- 50 psand power(mw 10 ~ 1). In this article, a complete overview of the studies which was done about soliton fiber lasers and the soliton wave propagation in an optical fiber…
Abstract Edge detection is one of the most decisive errands in involuntary image scrutiny. Edges portray precincts and are consequently a quandary of essential substance in image processing. Image Edge detection considerably diminish the quantity of data and sift out futile information, while defending the vital structural properties in an image. There subsists no general…
Abstract Digital watermarking is the efficient method to protect the digital information. Digital Watermarking is the method that embeds information known as a watermark into a multimedia object such watermark may be detected or extracted later to create an assertion regarding the object. Watermarking is either ”visible” or ”invisible”. Though visible and invisible are visual…

Abstract Present study deals with the consequents of sea water on ground water quality of Khajipalem village, Guntur District, Andhra Pradesh. The samples were collected from 06 places in different locations of the village in June 2015. The temperature, pH, DO, BOD, COD, Total hardness, fluoride, chlorides, Sulphates and nitrates were determined. All the parameters…
Abstract The complex nature of dynamic heat transfer through building parts is in need of computational analysis instead of applying simple mathematical techniques. An explicit finite difference method is applied to analyze a model wall of a building. And further computer simulation for results is done using MATLAB software by giving emphasis for parameters that…
