Download We Now Know. Rethinking Cold War History by John Lewis Gaddis PDF

By John Lewis Gaddis

Did the Soviet Union wish global revolution? Why did the USSR ship missiles to Cuba? What made the chilly conflict last up to it did? the tip of the chilly battle makes it attainable, for the 1st time, to start writing its heritage from a very foreign standpoint. in line with the newest findings of chilly battle historians and vast study in American records in addition to the lately opened documents in japanese Europe, the previous Soviet Union, and China, We Now Know presents a vividly written, eye-opening account of the chilly struggle through the years from the top of global warfare II to its most deadly second, the Cuban missile crisis.
We Now Know stands as a robust vindication people coverage in the course of the interval, and as a thought-provoking reassessment of the chilly battle through one in every of its so much uncommon historians.

Download Variational methods in nuclear reactor physics by Weston M. Stacey PDF

By Weston M. Stacey

Nuclear technology and know-how, quantity 10: Variational equipment in Nuclear Reactor Physics offers the mathematical equipment of a variational beginning which are worthwhile in acquiring approximate recommendations to technological know-how and engineering difficulties.

This booklet consists of 5 chapters and starts with a dialogue at the version rules for actual structures defined via either inhomogeneous and homogeneous equations to increase a generalized perturbation thought. bankruptcy 2 bargains with the purposes of variational estimates and generalized perturbation idea to neutron delivery difficulties. bankruptcy three covers the adaptation ideas of the Lagrangian shape which are developed for a common, linear- time-dependent procedure and for the explicit case of the P1 neutron kinetics equations. bankruptcy four provides the overall strategy for the variational derivation of synthesis approximations and their purposes to difficulties in reactor physics. This bankruptcy additionally examines the connection of the spatial synthesis and finite-element technique and a hybrid procedure that mixes good points of either tools. bankruptcy five describes the connection of edition thought with the Hamilton-Jacobi idea and with the optimization theories of the utmost precept and dynamic programming.
Nuclear physicists and researchers will locate this article necessary.
