Introduction to Process Control

•We assume that its mass flow rate w1 is constant, but the mass fraction of A, x1, varies with time. •Stream 2 consists of pure A and thus x2 = 1. •The mass flow rate of Stream 2, w2, can be manipulated using a control valve. •The mass fraction of A in the exit stream is denoted by x and the desired value (set point) by Xsp.

11. Diode Equivalence Circuits

Fundamentals of Electronic Circuit Design First Class AND gate: is such that the output voltage level is will be 1 if both inputs are a 1. Example 2: Determine the output level for the positive logic AND gate of fig: With 10v at the cathode D1 , is assumed that D1 is in the off state. D2 is assumed to be in the on state due to the low voltage at the cathode side and the

CHAPTER 3: CRYSTAL STRUCTURES

Crystal: Space Group By definition crystal is a periodic arrangement of repeating “motifs”( e.g. atoms, ions). The symmetry of a periodic pattern of repeated motifs is the total set of symmetry operations allowed by that pattern • Let us apply a rotation of 90 degrees about the center (point) of the pattern which is thought to be indefinitely
