The performance of the LED in LCM, for example life time or brightness, is extremely influenced by the characteristics of the LED driver. So all the parameters of an LED driver should be carefully designed and output current should be Constant current control. Please control feedback current of...
We prove that the reciprocal sum S k (x) of the least common multiple of k ≥ 3 positive integers in N ∩ [ 1 , x ] satisfies S k (x) = P 2 k - 1 (log x) O (x - θ k ) where P is a polynomial of degree 2 k - 1 and θ k = 2 k (k 1) k 1 2 · 3 2 ...
Let S={x_1,x_2,…,x_n}be a set of n distinct positive integers and a≥1 an integer. The matrix having the a-th power(x_i,x_j)~a of the greatest common divisor of x_i and x_j as its i,j-entry is called a-th power greatest common divisor(GCD)matrix defined on S,denote...
