Molecular dynamics for continuous potentials Short history: The first MD simulation for a system interacting with a continuous potential (Lennard-Jones potential) was carried out by A. Rahman in1964. A. Rahman, Phys. Rev. 136, A405, (1964). Main differences between MD with continuous poentials and

HEAT EXCHANGER NETWORK SYNTHESIS 1: TARGETING OBJECTIVES: 1 Determine the minimum energy inputs required for a process 2Determine the minimum number of heat exchangers required to transfer this energy 3Develop a methodology for determining where these heat exchangers should be placed in the process

ENGINEERING ECONOMICS I TO INVEST, OR NOT TO INVEST, THAT IS THE QUESTION. (With apologies to William Shakespeare) Given one or more potential projects, how do we decide in which to invest, if any? What criteria do we use to evaluate potential projects?
