The goal of the current research is to identify the possible usage of biosorbent, Gracilaria Corticata (Red Algae), used as an edible seaweed mostly in India is now used in abatement of lead & chromium from an aqueous solution. Batch scale experimental study was conducted to know equilibrium studies, kinetics & thermodynamics behavior of biosorption. The impact of several constraints like agitated time, biosorbent size, pH and dosage, initial concentration of metals, temperature of an aqueous solution were studied. The statistical optimization analysis was also done to generate response surfaces for the sample showing highest uptake capacity using response surface methodology by applying central composite design technique. It is observed that biosorption studies follow pseudo 2nd order kinetic model. The thermodynamic constraints showed biosorption of lead & chromium on the biomass was a spontaneous & endothermic process. As a result of the work showed the suggested bio sorbent could be an actual biomaterial for the elimination of lead ions rather than chromium from contaminated solutions.
To support humans in their daily lives, robots are required to autonomously learn, adapt to objects and environments, and perform the appropriate actions. We tackled on the task of cooking scrambled eggs using real in...

Now-a-days mobile robot is used to replace man power due to its ability to mimic activities of human beings. In this context, a trajectory exploration analysis with Khepera-III robot is carried out using modified wind driven optimization (WDO) controller. WDO is a metaheuristic optimization method that draws inspiration from nature. The controller is designed to control the robotic agents during steering in cluttered environments. Here, V-REP software is used to check the navigational capability of proposed controller. With simulation, it is found that the robot successfully achieved the goal post in an optimized way with less time consumption without any collision.
Diagnostics of machines operating at variable loads has been widely described in literature. The methods of analysing the vibroacoustic signals generated by such machines have been developed since the 1980s. They invo...

Every industry has needs recent development of techniques that are used in machines or apparatus. It can be reduced the processing time and defects in the production of components. The quality of the products is also better. In recent years, some difficulties are observed for the melting of metals in casting industries. The improper solidification rate may take place the casting defect problems due to none in the monitoring process. In this concept, an electric arc furnace has been developed through Resistance-Temperature-Detector (RTD) sensor for measuring temperature and can be introduced for a liquid sensor for measuring the molten level. Hence, the existing monitoring system was eliminated and the proposed system is attached to the furnace. The experimental investigation was conducted on aluminium 7068 alloys. The role of factor involvement was evaluated through the variance test and Pareto chart.
We describe size-varying cylindrical particles made from silicone elastomers that can serve as building blocks for robotic granular materials. The particle size variation, which is achieved by inflation, gives rise to...
