Must choose routes for various origin destination pairs(O/D pairs) or for various sessions - Datagram routing: route chosen on packet by packet basis Using datagram routing is an easy way to split paths Virtual circuit routing: route chosen a session by session basis Static routing: route chosen in a prearranged way based on O/D pairs Eytan Modiano

1. Hemoglobin is a multisubunit allosteric rotein that carries 02 in erythrocyte. 1.1 Hemoglobin is a well-studied and well-understood protein. 1.1.1 It was one of the first proteins to have its molecular mass accurately determined. 1.1.2 The first protein to be characterized by ultracentrifuge. 1.1.3 The first protein to be associated with a specific physiological function

by Andreas Hoffman Introduction This jumpstart shows you the basics of getting Scheme started, running simple programs, that the Scheme installed in the 16.410 computer lab is the Windows vers Ban On simple editing and debugging, and exiting out of Scheme. The jumpstart is oriented towards Windows installations, but can be adapted for Unix and other installations. Note Please note that this jumpstart will give you only the most rudimentary skills in Scheme

The Goal of this course: By studying this course, students can understanding kinetics, preparation and purification, and immobilization of enzymes. Also, knowing of applications and reactors of enzyme is another important task of students. Finally, students should master something in enzyme catalysis in organic media and some common, useful industrial enzymes

The constituents of concern found in wastewater are removed by physical, chemical, and biological methods. The individual methods usually are classified as physical unit operations, chemical unit processes, and biological unit ds in which the application of physical forces ohysical unit operations include pr T3clarifiers

1. The\Wager\and the Practical Rationality Principle Practical Rationality Principle: The practically rational thing to do is the thing with the highest expected value(or utility \) Version A: Do the thing with higher expected value than all its competitors --In the case of a tie, neither action/belief is permitted Version B: Find the actions with highest expected value and perform whichever of them you like --In the case of a tie, Theism is practically rational. Just like choosing pie over cake 2. Evidentialism(Clifford)

What is Online Learning? In an online lesson, the computer displays material in response to a learner's request. The computer promotes the learner for more information and presents appropriate material based on the learners response. The material can be traditional lessons and tests that are transcribed into a computer program. The material can also be a complex program that tracks users'input and
