  2. Hardy–Ramanujan–Littlewood circle method - Wikipedia

    en.wikipedia.org/wiki/Hardy–Ramanujan...

    Fractions with the same denominator have circles of the same size. In the special case when the circle method is applied to find the coefficients of a modular form of negative weight, Hans Rademacher found a modification of the contour that makes the series arising from the circle method converge to the exact result.

  3. Low-power electronics - Wikipedia

    en.wikipedia.org/wiki/Low-power_electronics

    Low-power electronics are electronics designed to consume less electrical power than usual, often at some expense. For example, notebook processors usually consume less power than their desktop counterparts, at the expense of computer performance .

  4. Hydrogen-powered aircraft - Wikipedia

    en.wikipedia.org/wiki/Hydrogen-powered_aircraft

    The hydrogen-powered Tu-155 prototype made its first flight on 15 April 1988.. A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor.

  5. Heaviside cover-up method - Wikipedia

    en.wikipedia.org/wiki/Heaviside_cover-up_method

    Here, we set up a partial fraction for each descending power of the denominator. Then we solve for the numerators, A and B. As ( 1 − 2 x ) {\displaystyle (1-2x)} is a repeated factor, we now need to find two numbers, as so we need an additional relation in order to solve for both.

  6. Rational number - Wikipedia

    en.wikipedia.org/wiki/Rational_number

    In mathematics, "rational" is often used as a noun abbreviating "rational number". The adjective rational sometimes means that the coefficients are rational numbers. For example, a rational point is a point with rational coordinates (i.e., a point whose coordinates are rational numbers); a rational matrix is a matrix of rational numbers; a rational polynomial may be a polynomial with rational ...

    Such a rapid power increase can also happen in a real reactor when the chain reaction is sustained without the help of the delayed neutrons. Suppose that the delayed neutron fraction for a particular reactor is 0.00700, or 0.700%. Suppose also that the reactor is highly supercritical and ΔK/K is 0.00700.

    “The Enron Egg is significantly more affordable than traditional energy systems, which cost between $19,000 and $50,000 while being subject to power fluctuations.

  9. Gender power gap - Wikipedia

    Countries like Argentina (3.9%), South Korea (2.1%), and Saudi Arabia (1.8%) were found to have the lowest gender power gap figures. [ 1 ] Further research with The Female Lead revealed 292 companies in the S&P 500 placed less than 10% of the value of corporate stock in women's hands. [ 10 ]
