Abstract: We reduce the expression of a radical identity that did not consider its source equation expressed in a cubic polynomial. Our method is applying algebra without using calculus technique to assist practitioners in the future solving their operational research questions from a pure algebraic point of procedure.

Keywords: Radical identity; Cubic formula; Reduction of radicals.

Abstract: Today's scenario is people on the earth are rapidly increased and according to that the number of vehicles on the road is also increased. Therefore, the problem of traffic management is arising specially for emergency vehicles. The idea behind this paper is to implement a system which would easily control the traffic and helps for the emergency vehicles to reach at their destination. This scheme relies completely on automatic intelligent control. Here the goal is to reduce the latency of emergency vehicles with minimum or less disruption to regular traffic flow is possible. However, there.......

Abstract: Power line communications technology was developed after the establishment of the power distribution network, it is considered to be one of the promising means of data transfer for home networks, and is a medium of shared transmission. Our study was based on the effectiveness of the CSMA/CA method, the collision occurs when the modems transmit at the same time, the transmitters draw the same backoff (a random waiting time) after another transmission. After.......

Key Word: Multiple collision; Resource sharing; Power line communications

Abstract: Investigate the cost of distributed photovoltaic power generation in different periods, use the payback period and internal rate of return (IRR) as economic evaluation indexes, and propose a new power generation estimation method for 20 years based on 3-year power generation data of actual cases to analyze the annual net revenue, revenue source ratio, payback period and IRR of distributed photovoltaic power generation systems in six periods. The results show that factors such as the amount of initial investment, government subsidy, provincial subsidy and the proportion of self-consumption limit the return on investment of photovoltaic systems built in different periods. With.......

Abstract: Effect of unwanted voltage and temperature variation on a newly commissioned 150MVA, 330/132/33kV power transformer at Afam Power Station, Port Harcourt, Nigeria, was investigated on 3rd-9th February 2019. There were issues relating to the remote display and operation of the Tap-changer and Temperature indicators vis-à-vis field tap position transmitters and temperature Relay transducers. Live tests, simulations and analysis to ascertain and rectify the technical issues arising duly conducted on and off field to give appropriate basis for correction of.....
