Discrete Mathematics, Chapter 11-13: Propositional Logic

2 Push negations inward by De Morgan’s laws and the double negation law until negations appear only in literals 3 Use the commutative, associative and distributive laws to obtain the correct form 4 Simplify with domination, identity, idempotent, and negation laws (A similar construction can be done to transform formulae into disjunctive

Chapter 3 Predicate Logic

De nition 20 A predicateis a statement that contains variables (predicate variables), and they may be true or false depending on the values of these variables Example 22 P(x) = \x2 is greater than x" is a predicate It contains one predicate variable x If we choose x= 1, P(1) is \1 is greater than 1", which is a proposition (always false) 77

1Ce nombre de 220 peut sembler très élevé mais il ne faut pas oublier que le nombre choisi 253 est le produit des deux nombres premiers 11 et 23 Donc, dans la liste de tous les nombres allant de 1 à 253, il suffit de supprimer tous les multiples de 11 (il y en a 22) et tous les multiples de 23 (il y en a 10)

Mathematical Modelling of Wind Turbine in a Wind Energy

dE dt = 1 2 dm dt v2 w (4) But mass ﬂow rate dm dt is given by dm dt = ρAv w where A is the area through which the wind in this case is ﬂowing and ρ is the density of air With this expression, equation (4) becomes P = 1 2 ρAv3 w (5) The actual mechanical power P w extracted by the rotor blades in watts is the
