costefficiency of a hybrid approach—an attractive feature for institutions faced with shrinkingbudgets and classroom space—Brown13 posits that, in the future, institutions will design mostcourses by the 90–10 Rule Q (p. 22). In other words, a mix of face-to-face and online instruction(somewhere between 90% and 10% and 10% and 90%) will be superior to either 100% face-to-face or 100% online courses6. The findings of a study show that online learning can be aseffective as face-to-face learning in many respects in spite of the fact that students in onlineprograms may be less satisfied with their experience than students in more traditional learningenvironments14.

The circuit remembers which of the two input variables, S or R, was most recently a 1,by recording on the output variable, Q, a 1 if it was S or a 0 if it was R. By realizing that this SRlatch, the most fundamental memory circuit in any static memory device, is actually anasynchronous finite state machine, one realizes the fundamental nature of this topic.

analysis process. For any case, the first step in obtaining the wind loads is to determine the appropriatedynamic wind pressure. This pressure is obtained by treating the air as a perfect fluid and notingthat when wind strikes an object (a bluff body) in its path, the kinetic energy of the moving airparticles is converted to an effective dynamic wind pressure. This effective dynamic windpressure, q, at any height above ground is given by the following equation (Equation 6-13 inASCE 7):q z = 0.00256 K z K zt K d V 2 I (lb/ft2) (1)where,q = effective dynamic velocity pressure to be used in the appropriate equation to evaluate the effective static wind pressure for main wind-force
