Queueing Systems Used for analyzing network performance In packet networks, events are random Random packet arrivals Random packet lengths While at the physical layer we were concerned with bit-error-rate, at the network layer we care about delays How long does a packet spend waiting in buffers

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

Prof. Sally Haslanger December 2, 2001 Kantian Ethics (and more on famine) So far we've looked at egoist and utilitarian approaches to ethics. The main objection we considered to egoism was that it failed to accommodate the common sense idea that morality involves a kind of impartiality, at the very least it seems that

Number Theory I Number theory is the study of the integers. Number theory is right at the core of math ematics; even Ug the Caveman surely had some grasp of the integers- at least the posi tive ones. In fact, the integers are so elementary that one might ask, What's to study?

Different Sort of Personal Identity:\Ethical\ Identity . Personal Identity: \Ethical\v. \Metaphysical\questions The previous lectures and readings on personal identity were primarily concerned with the metaphysics of personal identity. Question of diachronic identity/unity: Confronted with an individual X at one time and Y at another, what would make it the case that X and Y are (or are parts of) the same person? We've seen that the answer to this question may well depend on what sort of thing you think persons are: are persons bodies? Streams of consciousness?
