Scalefactors are introduced in order to normalize the dimensionless variable to be of order one,whereas reference factors are introduced in order to reference the dimensionless dependent orindependent variable to zero. Note that we have scaled all the dependent and independentvariables. Note also that we have considered the adsorption rate to be a dependent variable that isscaled by qs . It is not necessarily true that the adsorption rate would be scaled by qs t s , sincethe amount adsorbed might not experience a characteristic change of qs over the characteristictime ts . Recall here that our goal is to scale all the above dependent

Engineering andmathematics maintained a similar trend in the distribution of grades. In engineering,approximately twenty-seven percent of the grades given were A s, while 20 percent of thestudents failed. A-, B+, B, B-, C+, and C grades represented the remaining 53 percent.Mathematics department awarded approximately 20 percent A grades and had a 24 percentfailing grades. This research indicates that the academic standards for engineering andmathematics departments were not compromised over the period from 1993 to 1999.In

As can be seen, the total harmonicdistortion caused by the small nonlinear loads is in the range of 30%. A major problem of hybridpower generation systems is their sensitivity to nonlinear loads. Figure 11 depicts a major loadchange situation. This figure is battery voltage when a large load of 8 A is connected at 5 s and aload of 9 A is connected at 54 s. The battery takes almost 30 s to recover from the voltage sagcaused by the large load changes.

If a particular student has reviewed the design document for a project, forexample, there are advantages in having him (her) also review the finished project. If groups ofstudents work on a single project, students may be randomly assigned to review other student(s)within the same group [Topp 00]; let us call this Strategy G.One variant of Strategy G was used by Henderson and Buising [HB00].

In order to learn about system components,the user is expected to point a curser at the appropriate area within the digital photograph thatwill result in a special window providing a textbook-quality description of the relevant systemcomponent(s).

However,in most tissues scattering cannot be ignored and contributes significantly to light distribution.In this case it is no longer possible to use a simple, intuitive model like Beer’s law to predictlight distributions. In its most general form for situations where both absorption andscattering play a role, spatial light distribution is described by the light transport equationwhich relates the gradient of radiance at some position ‘r’ in direction s to losses due toabsorption and scattering and gain due to scattering
