Repeat the work of Widrow and Hoff on a pattern recognition problem from their classic 1960 paper [WiHo60]. They wanted to design a recognition system that would classify the six patterns shown in Figure P10.11.
These patterns represent the letters T, G and F, in an original form on the top and in a shifted form on the bottom. The targets for these letters (in their original and shifted forms) are +60, 0 and -60, respectively. (The values of 60, 0 and -60 were nice for use on the face of a meter that Widrow and Hoff used to display their network output.) The objective is to train a network so that it will classify the six patterns into the appropriate T, G or F groups.
Assume you are an observer standing at a point along a three- lane roadway. All vehicles in lane 1 are traveling at 30 mi/ h, all vehicles in lane 2 are traveling at 45 mi/ h, and all vehicles in lane 3 are traveling at 60 mi/ h.

A simple highway curve is planned to connect two horizontal tangents that intersect at sta. 2500+00.00 at an external angle of 52°. For a design speed of 60 mi/h and a curve radius of about 1.25 times the minimum allowable
A dispersed plug chemical reactor has an influent flow with concentration of 150 mg/L of A and a flow rate of 100 gal/min (380 L/min). The reaction is first order, The rate equation : - dC/dt = kC= -r , and the rate constant is 0.4 h^-1 .
