Study on use of Saw Dust Ash as Replacement of Cement in Concrete IJTSRD
Scientists, Engineers and Technologists are continuously on the lookout for materials which can be used as substitutes for conventional materials or which possess such properties that would enable their use for new designs and innovations. Applications of Concrete alternative materials fall under the first category. The raw materials for making cement and aggregates are essentially […]
A Preliminary Study on Aerated Geopolymer using Calcium Carbide IJTSRD
In this paper a preliminary study is conducted on use of calcium carbide as an aerator in geopolymer paste and mortar. A 12 mole sodium hydroxide with sodium silicate solution was mixed with fly ash in 1 2 ratio to create geopolymer paste. To make mortar, graded sand was used as 3- parts with 1-part […]
Crowd Sensing Systems A Mini Review IJTSRD
The main purpose of crowd sensing systems is to extract information based on the crowd in environment. . This paper briefly explains each type of sensors that were widely used in real life situations. Each type of sensors is covered from basic understanding, tools, method of algorithm, their finding, way of conducting test, and results. […]
Analysis of Dual-axis Solar Tracking System by using Lock Anti-Phase Drive Method IJTSRD
Solar energy is rapidly advancing as an important means of renewable energy resource. Many of the solar panels throughout the world are positioned with the fixed angles. Solar tracking enables more solar energy to be generated because the solar panel is able to maintain a perpendicular profile to the sun’s rays. Solar trackers move the […]
Image Denoising for AWGN Corrupted Image Using OWT and Thresholding IJTSRD
In this work, review of various well-known algorithms for image denoising is carried out and their performances with their methodologies are comparatively assessed. A new algorithm based on the orthonormal wavelet transform OWT is developed. In this work images corrupted by AWGN are denoised. Simulation results shows that proposed method using Orthonormal wavelets for different […]
