The results presented in Table 4 show that RAS reduced the total distance traveled and the number of buses needed. In the Real Case it was traveled 48‚507.80 km using 55 buses while RAS planned 41‚217.44 km using 39 buses in the best solution. This reduction was possible by increasing the bus occupancy rate‚ from 68.98% in the Real Case to 97.28% in the best solution of RAS. The solution found by RAS leads to a monthly gain of US$ 250‚935.55 and an annual gain of US$ 3‚011‚226.55 (by multiplying

Here there can be numerous kinds of bonding forming a straight chain or long chain polymer. More over the number of repeating units are also much greater than giving the structure variation. Carbohydrates can be broken down into monosaccharides which is a single sugar unit that can be glucose‚ fructose and galactose. This is called catabolism. Disaccharides

bits at the inputs and indicate the presence of that particular set of bits by outputting a specified output level. Typically a decoder with n input lines require 2n output lines to decode every possible combination of bits. BCD to decimal conversion‚ looked at in part 3 of this lab‚ is accomplished using a decoder which has 4 input lines and 10 output lines (the 10 output lines correspond to the decimal numbers 0-9). This device is used to convert between binary numbers and decimal numbers. Encoders:
