ECS3704 STUDY GUIDE. In a perfect world - a limited role for government (“order functions”).  In the real world - a more comprehensive role for government. Why? In solving the economic problem the market fails in terms of  efficiency (Ch 2, 3 & 4)  equity (Ch 5)  Allocative efficiency (a normative approach)  measure is Pareto norm - where it is impossible to increase utility/output of one person/sector without reducing that of another,ie, utility (of consumers) is...

How do we predict weather? correct answers Through models What is a model correct answers a tool for simulating or predicting the behavior of the atmosphere How soon can you predict the weather? correct answers No more than a week or two in advance Heuristic Model correct answers rule of thumb based on experience or common sense (not always accurate or reliable) example: if the winds get strong, there'll be a lot of damage Conceptual Model correct answers framework for understanding...

Degrees of Freedom - The minimum number of independent coordinates required to completely determine the position of all parts of a system at any point in time. Discrete or Lumped Parameter System - System with a finite number of degrees of freedom. Continuous or Distributed Parameter System - System with an infinite number of degrees of freedom. Free Vibration - :Excitation due to initial conditions, or, equivalently, storedenergy. Forced Vibration - Excitation due to external forces or in...
