" 8.10 Suppose we want to add an extra operation, deunion, which undoes the last union operation that has not been already undone. Show that if we do union-by-height and finds without path compression, then deunion is easy, and a sequence of M union, find, and deunion operations takes O(M logN) time. Why does path compression make deunion hard

Which one from below is not one of the reasons of planning failures? (clo3) a)-planner is careless. b-planner spend less time in the field but more time on the desk c)-planner is not qualified d)-planner does not have sufficient time to properly plan

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?

How to increase the thermal officiency of an ideal simple rankino cycle? among these methods, which one is the best and why?
