The change in volume or shape of an object that results from stress is called strain. The response of rocks to stress can be divided into - elastic response: rock returns to original shape - ductile or plastic response: permanent deformation without fracture; occurs above the so-called elastic limit
Ideal response Want Ideal Response to Signal -usuall straight-line function Actual response is determined by values of control factors and noise factors If noise factors are suppressed early, the en difficult problems only appear late Introduce noises early C Don Clausing 1998

Managerial Decision Making Decision making: the process by which managers respond to opportunities and threats by analyzing options, and making decisions about goals and courses of action. oDecisions in response to opportunities: managers respond to ways to improve organizational performance. ODecisions in response to threats: occurs when managers are impacted by adverse events to the organization
Thus far have considered only static response. However, things also move, this includes structures Can actually identify three \categories\ of response A.(Quasi)-Static [quasi because the load must first be applied
Phase and Group Delays The output y[n] of a frequency-selective LTI discrete-time system with a frequency response(@) exhibits some delay relative to the input x[n] caused by the nonzero phase response 0(@) =arg{()} of the system
