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.
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. The largest number of these are from 1560, a set for an entire orchestra of 38 ordered by Catherine de Médicis the regent queen of France and bore hand painted royal French decorations in gold ...
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.
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 ...
Born in Cremona, Andrea Amati's son and Girolamo Amati's brother, Antonio worked first with his father, then with his brother, in the same workshop. With the latter, he refined his construction technique and style. For about ten years, they co-signed their works with their Latinized names: "Antonius & Hieronymus Amati"
The models, first reported by Reuters, are capable of reasoning through complex tasks and can solve more challenging problems than previous models in science, coding and math, the AI firm said in ...
These limits reflect what the process will deliver without fundamental changes. [3]: 43 Points outside of these control limits are signals indicating that the process is not operating as consistently as possible; that some assignable cause has resulted in a change in the process. Similarly, runs of points on one side of the average line should ...
An increase in this variable means the higher pole is further above the corner frequency. The y-axis is the ratio of the OCTC (open-circuit time constant) estimate to the true time constant. For the lowest pole use curve T_1; this curve refers to the corner frequency; and for the higher pole use curve T_2. The worst agreement is for τ 1 = τ 2.
