the 9m120 ataka russian: атака; attack is an anti-tank guided missile atgm originating from the soviet union. the nato reporting name of the 9m120 missile is the at-9 spiral-2. it is the next major generation in the 9k114 shturm at-6 spiral family. the missile has radio command guidance and is also a beam riding saclos.
wikimedia commons has media related to evolutionary algorithms.: an evolutionary algorithm ea is a heuristic optimization algorithm using techniques inspired by mechanisms from organic evolution such as mutation, recombination, and natural selection to find an optimal configuration for a specific system within specific constraints.
a spiral sometimes called a spiral loop or just loop is a technique employed by railways to ascend steep hills.. a railway spiral rises on a steady curve until it has completed a loop, passing over itself as it gains height, allowing the railway to gain vertical elevation in a relatively short horizontal distance.

magellanic spiral galaxies are usually dwarf galaxies which are classified as the type sm and sam, sbm, sabm .they are galaxies with one single spiral arm, and are named after their prototype, the large magellanic cloud, an galaxy. they can be considered to be intermediate between dwarf spiral galaxies and irregular galaxies
the following outline is provided as an overview of and topical guide to galaxies: . galaxies – gravitationally bound systems of stars, stellar remnants, interstellar gas, dust, and dark matter. the word galaxy is derived from the greek galaxias γαλαξίας , literally 'milky', a reference to the milky way. galaxies range in size from dwarfs with just a few billion 109 stars to .
in woodworking and construction, a nail is a small object made of metal or wood, called a tree nail or 'trunnel' which is used as a fastener, as a peg to hang something, or sometimes as a decoration. generally, nails have a sharp point on one end and a flattened head on the other, but headless nails are available. nails are made in a great variety of forms for specialized purposes.
spiral bevel gears have curved teeth at an angle allowing tooth contact to be gradual and smooth. zerol bevel gears are very similar to a bevel gear, but the teeth are curved: the ends of each tooth are coplanar with the axis, but the middle of each tooth is swept circumferentially around the gear. zerol bevel gears can be thought of as spiral .

natural evolution strategies nes are a family of numerical optimization algorithms for black box problems. similar in spirit to evolution strategies, they iteratively update the continuous parameters of a search distribution by following the natural gradient towards higher expected fitness.
history. the 'evolution strategy' optimization technique was created in the early 1960s and developed further in the 1970s and later by ingo rechenberg, hans-paul schwefel and their co-workers.. methods. evolution strategies use natural problem-dependent representations, and primarily mutation and selection, as search operators.in common with evolutionary algorithms, the operators are applied .
a francis turbine consists of the following main parts: spiral casing: the spiral casing around the runner of the turbine is known as the volute casing or scroll case. throughout its length, it has numerous openings at regular intervals to allow the working fluid to impinge on the blades of the runner. these openings convert the pressure energy .
this feature causes the tap to continuously break the chip and eject it forward into the hole, preventing crowding. spiral point taps are usually used in holes that go all the way through the material, so that the chips can escape. another version of the spiral point plug tap is the spiral flute tap, whose flutes resemble those of a twist drill .
