Problem 1. An undirected graph G has width w if the vertices can be arranged in a se- quence V1,2,3,…,Vn such that each vertex v; is joined by an edge to at most w preceding vertices. (Vertex vj precedes if i.) Use induction to prove that every graph with width at most w is (w+1)-colorable
What is life? 人生是路,铺满鲜花,也布满荆棘。 人生是烛,照亮别人,却燃尽自己。 Life is a road, strewn with flowers and beset with brambles. Life is a candle, illuminating others and burning itself out. 生不带来,死不带去。 At birth, we bring nothing; at death we take away nothing
As an example of one-quadrant converter a buck converter (also known as step-down converter)is presented in the picture below. The name of the step-down converter results from the arithmetic mean at the output side which is less than the arithmetic mean at the input

This equation accounts for the kinetic data given in Figure 8-15.At very low substrate concentration, when [S] is much less than KM, V [s]Vmax/KMi that is, the rate is directly proportional to the substrate concentration At high substrate concentration, when [SI is much greater than KM, V=Vmax; that is, the rate is maximal, independent of substrate
6.1 Definition Definition: A queue is a linear list in which additions and deletions take place at different ends. It is also called a first-in-first-out list. The end at which new elements are added is called the rear. The end from which old elements are deleted is called the front
