The vehicles on road are increasing with rapid rate which is good by transportation perspective and hence the growing need of oil-based fuel making transportation costly as the price of oil based fuel rising too. The quantity of oil-based fuel remains unchecked and the exhaust from oil-based fuel brings environmental problems like ‘‘green house effect’’, health issues for the operating environment. The electric vehicles is a good option for moving away with problems related to the oil-based fuel lot of researches is going on in world and money is being spent on the development of the electric vehicles. The problem related with electric vehicles are electric vehicles have low speed, having low load carrying capacity, and batteries having short life. The main aim of this research paper is to give an idea about fabrication of simple, cost effective electric motorcycle which can be done by replacing internal combustion engine and other components with brush less direct current gear motor, controller and lithium-ion battery. This electric motorcycle uses 48V 750w brushless direct current gear motor to propel the vehicle, lithium-ion battery as power source the brushless direct current motor. The 48v 750w brushless direct current gear motor have high load carrying capacity with acceptable speed and lithium-ion battery have more life than other batteries available in market such as lead acid battery. The lithium-ion battery has less weight, quick charge property, required less storage space compare to other batteries available in market.

Torque ripple reduction is one of the major challenges in switching table-based direct torque control (DTC) while operating for open phase faults of an induction motor, as the switching vectors are unevenly distributed. This can be minimized by increasing the level of the inverter and with the use of multi-phase motors. Fuzzy logic-based DTC is another solution to the above problem. In this paper, a comparative analysis is done between switching table-based DTC (ST-DTC) and fuzzy logic-based DTC for increasing the performance during open phase faults of a five-phase induction motor. The result shows that in fuzzy logic-based DTC with a two-level inverter, the torque ripple is reduced by 5.164% as compared with ST-DTC with a three-level inverter. The fuzzy logic-based DTC with the three-level inverter also gives better performance as compared with fuzzy logic-based DTC with the two-level inverter. The current ripple also reduced by 9.605% with respect to ST-DTC. Thus, fuzzy logic-based DTC is more suitable and cost effective for open phase fault-tolerant drives.

Abstract Wireless Autonomous Nano-sensor Device (WAND) system is a disruptive cost-effective micro-system for well monitoring. It allows to realize pressure, temperature, inertial, and magnetic field measurements in harsh conditions; it also offers Bluetooth low-power communication and Wireless charging capabilities. Analysis’ results of an industrial offshore pilot realized in Congo (a world first in O&G industry in such complex environment), and major improvements implemented after this pilot are reported in this paper. Accomplished advancements comprise hardware and software developments extending operation lifetime, and simplifying on-site utilization. To date, there is not a commercial solution of this type in the market, the realization of this project is a real innovation allowing practical and low-cost monitoring during well intervention while minimizing the risks associated with standard Rigless intervention. Other applications regarding dry-tree wells on tension-leg platforms (TLP), drilling and completion operations, and pipeline monitoring are being investigated, too.
