MOVING CASHLESS, YOUR MONEY MIGHT BE AT RISK, MONEY FRAUD METHODS AND PREVENTION

India is a big nation moving towards a cashless economy, cashless economy need awareness among people to prevent themselves from money fraudsters. Number of money fraud are reported in last few years through cards and internet baking. Till now the cashless transaction was done at very low rate before demonetization announced by PM of India on 8th of November 2016.  Afterwards the cashless transaction increased dramatically in the country. Government of India is also promoting the plastic money (Debit/Credit Cards)  and online transaction. Providing various discounts to promote cashless transaction through credit – debit cards, internet banking, e-wallet etc. Information…

Do The New 2000 Rupees Note have An Inbuilt Nano GPS Chip ? Is it possible in Near Future ?

Just after announcement by Prime Minister of India regarding demonetization of old 500 and 1000 rupees notes and legal tender of  new  500 and 2000 Rupees notes, rumors are spreading on social media and news channels that the new 2000 rupees note have an inbuilt nano GPS chip (NGC) to track the location of currency if stocked in the form of unaccounted black money. Let us discuss about the reality and possible scope for such feature in a currency Note. The Nano GPS Technology Since announcement of new notes circulation, everyone is talking about the new inbuilt NGC chip in…

COMMON CURVES USED IN ENGINEERING PRACTICE

In engineering practice we see many objects having curved surfaces or edges. Every curve has a name and property which defines it. Point is the basic identity in a drawing. All curves are obtained by the path traced by a point while moving in a constrained motion. Most commonly used curves in engineering practice are 1.    Conic Sections: – These are the curves obtained on having sections of a right circular cone by a plane from different positions relative to the axis of cone. Circle, Ellipse, Parabola and Hyperbola are the curves defined by conic sections. 2.    Cycloidal Curves :-…

RAINWATER HARVESTING FOR BORE WELL RECHARGING

Water is an essential for all living organism. In fact no life is possible without water. Bore wells are the common source for water in rural as well as urban areas. In summers the water level decreases and at some water deficient areas, the bore wells give-up the supply and get dry. In our ecosystem the water cycle or hydrological cycle in which water carried out from lakes, oceans, rivers, ponds etc in the form of water vapors. These vapors forms cloud and again these clouds turn into rain and supply water. Thus rain water is the natural source of…

SCIENTISTS ACCIDENTALLY INVENTED A NEW BATTERY THAT COULD LAST FOREVER WITH NANO WIRES

Batteries are the essential part of our everyday life equipments, gadgets, vehicles etc. All mobile and immobile equipments which relies on a energy storage packs eat up batteries after a specific cycle life. Efficiency and cycle life are the two major factors and subjects of continuous research and development. Nobody wants to plug a device for charging too frequently, and for long time. Even no researcher is willing to face accidents in laboratory while performing an experiment, unless it leads to a new Invention. Mya Le Thai a PhD candidate at University of California, Irvine. While performing an experiment, She…

SOLAR CHARGE CONTROLLERS THE BATTERY LIFE ENHANCERS

Charge controllers, also known as charge regulators are an integral part of the solar power systems and are often termed as battery life enhancers. These devices limit the amount of current drawn and fed to the batteries bank, which stores DC energy from the solar panels. Life span of a battery is curtailed if overcharged and same is the case when current is drawn in an under charge condition. The charge controller circuit is intelligent enough to tackle both these situations by allowing or suppressing amount of charge to the batteries. In case of solar systems, Most 12 volts panels…

SOLAR INVERTERS – EFFICIENT AND ROBUST SOLAR POWER INVERTERS

Solar power is one of the most convenient and readily available form of renewable energy. Scientists have devised the methodologies and technologists have created the stuff employed for conversion of heat and light of solar rays into electricity available at our home outlets. Some specialized genre of semi conductor materials that exhibits photovoltaic effect i.e. these material produce direct current in response to incident light, are used in the fabrication of solar plates combined in the form of arrays. Each single plate is a combination of a huge number of solar cells with each cell producing voltage output in the…
