Comparing Consistency Limits of Black Cotton Soil with Cement Waste Dust and Wood Shaving Ash
Abstract: In the field of civil engineering, soil has to play a prime role right from planning a structure to the end of life of that structure. But some of the soils do not offer that service which a civil engineer wants to get. Shrinking in dry state and swelling in wet state, is the well-known proved proverb for black cotton soil. In Saurashtra, southern part of the zone has such …

PROJECT PLANNING AND CONSTRUCTION USING ROBOTICS AND AUGMENTED REALITY
Abstract: The construction industry is based on human resources, specifically for on-site construction processes. The conventional construction practices require an absolute amount of workforce and skilled labour to achieve the aimed efficiency in terms of construction duration and cost, and building quality. Besides, lack of workforce and sufficiently skilled labour can affect the overall duration, cost, and quality targets. Therefore, based on these issues, advanced robotic technologies have been developed to …

Design and Analysis of Multi Band Patch with Enhanced Bandwidth
Abstract: In this article, a novel lower edge defected multi-band patch with modified ground structure (or Defected Ground Structure-DGS) with enhanced bandwidth has been presented. The bandwidth can be enhanced by defecting the partial ground and by arc truncation of lower edges of the patch. The antenna was converted into multi-band by defecting the lower corners. The antenna is resonating at multiple bands i.e. 3.7 GHz, 7.87 (~7.9) GHz, 12.19 (~12.2) …

Structure and Cube Texture Development Trend of Al4.5MgMn Alloy at Variable Annealing Conditions
Abstract: Hot-rolled Al4.5MgMn alloy was cold rolled to true strain levels 0.8, 1.6 and 2.3. Annealing at 300°C, 350°C and 400 °C was done to develop annealing structure. The annealed structures were measured by SEM-EBSD. The average grain size and grain size distributions were measured using Sigma-scan-Pro 5 structure analysis software. The average grain size and grain size distributions showed higher number frequency of lower annealing grain size with the increase …
