KV

Köchel catalogue The Köchel catalogue (German: Köchel-Verzeichnis) is a chronological catalogue of compositions by Wolfgang Amadeus Mozart, originally created by Ludwig Ritter von Köchel, in which the entries are abbreviated K. or KV.

The indication "K." or "KV" refers to Köchel Verzeichnis (Köchel catalogue), i.e. the (more or less) chronological (i.e. by composition date) catalogue of Mozart's works by Ludwig von Köchel.

A lot of composers' music is listed by opus number (abbreviated Op.), but back in the 19th century, a musicologist named Köchel (Ludwig Alois Ferdinand Ritter von Köchel, to be exact) did the world a huge favor by cataloguing all of Mozart's music. So Mozart's compositions have “K. for Köchel” numbers.

The Symphony in B-flat Major, K 22 (1765; “K” or “Köchel” numbers - named for Ludwig, Ritter (knight) von Köchel, the scholar who catalogued Mozart's musical corpus - are the standard way of identifying Mozart's works) contains a lovely chromatic slow movement in the key of G minor.

The Kv rating designates the RPM a motor will spin at full throttle when unloaded given an input voltage. To estimate the RPM of a motor, simply multiply the Kv value by the battery voltage. Kv is in units of RPM/Volt.

Mechanically speaking, low Kv motors have a higher number of windings of a thinner wire and the thin wire carries more volts at lower current. High Kv motors have fewer windings but a thicker wire that can carry higher current with fewer volts.

Einstein started taking violin lessons at age five, but the drills were so trying that he threw a chair at his teacher. It was Mozart's violin sonatas that finally had him hooked at age 13. "Mozart's music is so pure and beautiful that I see it as a reflection of the inner beauty of the universe," he said.

595. Ralph Kirkpatrick catalogued the numerous works of Domenico Scarlatti in a facsimile edition, and so these pieces are also given a K number, usually written “Kk” to distinguish it from Mozart's Köchel number.

Classical k-means algorithm k-means is an unsupervised learning algorithms which addresses the clustering problem. The following are the high level steps of classical k-means algorithm: We need to define “k” so that the data set can be clustered into k-subsets.

Mozart composed about 20 solo piano sonatas, from roughly 1775 through the summer of 1789. Midway through that sequence is the Sonata in A, K 331. (The “K” refers to Ludwig, Ritter [knight] von Köchel, a 19th-century Austrian musicologist who compiled the most complete chronological catalog of Mozart's works.)

Kv describes the RPM (revolutions per minute) a motor does per Volt that is put into it. Generally speaking the more Kv a motor has, the more RPM and more power. For example, a 9000Kv motor would be faster than a 2200Kv motor. If Kv is like horsepower, then Turns is the physical attribute of a motor.
