Automated and High Speed Mechanical System for Loading and Feeding Clutch Release Bearing and Hub for Assembly and Rotating That Assembly by 90˚ in Automobile Industries
No full textThe agenda of this research poster is to design fully automated high-speed mechanical system which should be cost effective as well. The purpose of designing this system is to assemble two plates and their inspection for a batch or lot production at high-speed. To relate this to real world application in the automobile industry, the whole operation is performed to carry out an assembly of clutch release bearing and its hub. Automated tools like rod less pneumatic cylinder and gripper unit, mechanical flipper wheel, precision indexing conveyors and proximity laser sensors have been used to complete the required tasks at high-speed and with high accuracy. This system is designed and modeled using Creo Parametric 2.0 and its computer-aided structural analysis is carried out with the help of ANSYS Workbench 16.0
Characterization and the state variable estimation of a carbon foam lead acid rechargeable battery
No full textThe composite plate material of the carbon foam electrode battery is lighter, longer living, and has higher active material utilization than current lead acid systems. It is also one of the few lead-acid batteries that can operate for extended time in partial-states-of-charge. The battery includes carbon-foam electrodes for the negative plates, which gives it a performance that is comparable to NiMH but at lower manufacturing costs. In the work, a carbon foam electrode battery is characterized. With an equivalent, a linear system can be used to estimate the state variables in the model

Development of efficient obstacle avoidance and line following mobile robot with the integration of fuzzy logic system in static and dynamic environments
No full textAutonomous mobile robots have been widely used in many researches and applications. Mobile robots can be programmed to do specific tasks such as collision avoidance and trajectory planning. Various types of sensors and actuators are mounted on these robots for sensing the surrounding environment and making decisions accordingly. In this paper, we develop collision avoidance and line following techniques for mobile robot navigation in static and dynamic environments with the integration of fuzzy logic fusion. For the collision avoidance technique, eight proximity sensors are used to detect static and dynamic obstacles. The proposed fuzzy logic for the line following mechanism consists of one input and two outputs. The input is the difference between right and left ground sensors values whereas the outputs are the left and right speeds to steer the mobile robot. Several membership functions and fuzzy rules are designed. The proposed method has been successfully tested in Webots Pro simulator and in real time experiment
“R22” – An Unbreakable, Un-hackable, Friend-to-Friend Encryption System
No full textThis project begins a discussion of creating a secure “friend-to-friend” messaging scheme that involves only ordinary computers on the “surface web, does not depend on the difficulty of factoring, is impervious to any kind of deliberate or accidental backdoors, does not use any third party random number generators, and is unbreakable in any reasonable amount of time
Bacillus licheniformis (ATCC 14580) inhibitory activity against opportunistic fungi
No full textB. licheniformis (ATCC 14580) will exhibit antifungal properties by inhibiting mycelial development when exposed to specific opportunistic fungi as a filtrate. The common soil-dwelling endophytic bacterium B. licheniformis, strain CHM1, has been shown to inhibit growth from several pathogenic fungi. Phytopathogenic fungi (i.e. Fusarium oxysporum, Phytophtora infestans, Penicillium digitatum, etc...) possess the capability to infect and cripple small to large-scale agricultural crop harvesting operations (Wang et al 2009). The development of preventative methodologies and techniques are vital in order to suppress and contain phytopathogenic fungi within agricultural operations. Without preventative methodologies coupled with increasing global populations, agricultural fungal outbreaks could result in local to national-scale economic inflation and hardships
