Andrea Amati (ca. 1505 - 1577, Cremona) was a luthier, from Cremona, Italy. [1] [2] Amati is credited with making the first instruments of the violin family that are in the form we use today. [3] Several of his instruments survive to the present day, and some of them can still be played.
First order LTI systems are characterized by the differential equation + = where τ represents the exponential decay constant and V is a function of time t = (). The right-hand side is the forcing function f(t) describing an external driving function of time, which can be regarded as the system input, to which V(t) is the response, or system output.
A claim that Andrea Amati received the first order for a violin from Lorenzo de' Medici in 1555 is invalid as Lorenzo de' Medici died in 1492. A number of Andrea Amati's instruments survived for some time, dating between 1538 (Amati made the first Cello called "The King" in 1538) and 1574.
Cello: with 'The King Violoncello' by Andrea Amati being the earliest known bass instrument of the violin family to survive. [55] Centrifugal Pump: the first machine that could be characterized as a centrifugal pump was a mud lifting machine that appeared as early as 1475 in a treatise by the Italian Renaissance engineer Francesco di Giorgio ...
The second order time constant, , is simply the time constant associated with the reactive element (where subscript always denotes the index of the element in question), when element is infinite valued. In this notation, the superscript always denotes the index of the element (or elements) being infinite valued, with superscript zero implying ...
(Reuters) -Microsoft-backed OpenAI said on Thursday it was launching its "Strawberry" series of AI models designed to spend more time processing answers to queries in order to solve hard problems.
The violin-like instruments that existed when Amati began his career only had three strings. Amati is credited with creating the first four stringed violin-like instrument. The first sentence appears to be a leap from hearsay of an unsubstantiated 19th century report to it being held that the report is true.
where resistance in ohms and capacitance in farads yields the time constant in seconds or the cutoff frequency in hertz (Hz). The cutoff frequency when expressed as an angular frequency ( ω c = 2 π f c ) {\displaystyle (\omega _{c}{=}2\pi f_{c})} is simply the reciprocal of the time constant.
