In addition, only a modest amounton non-calculus mathematics is required for the student to gain an adequate understanding oftransceiver design concepts.Professor Rutledge's textbook uses an off-the-shelf 7 MHz RF transceiver kit known as theNorCal 40A as a vehicle for teaching RF circuit analysis and design.

universities, a survey wasadministered to several classes at UNO. The survey was based on part of a recent large scalestudy called the PACE-1 Study, involving a seven section survey of 643 undergraduateengineering and pre-engineering students at eleven institutions, ranging from communitycolleges to large research universities. The PACE-1 study attempted to determine what is studentcheating, how often does cheating occur, why do students cheat, and what methods can be usedto reduce or stop cheating. Because of time constraints, the UNO survey was based on the firstsection of the PACE-1 survey. The UNO questionnaire was a short one-page voluntary surveythat was given at the beginning of several large undergrad classes in order to try to determinewhat

One exercise is presented in Example 1pertaining to the topic of stability and determinacy of a truss shown in Figure 1. The feedbackinformation is also included in each exercise. This exercise is for the students to recognize thefundamental differences between a stable structure and an unstable structure, and also between astatically determinate structure and a statically indeterminate structure. The second differenceleads to the recognition of a situation where Statics alone is not adequate for solution of theproblem. Example 2 is on effects of moving loads on a beam.

Thus as a set, an intensity histogram of an image can be written as H = { h(k) |k = 0, 1, 2, …, L-1}. Here H is the composite histogram and h(k) is the histogram value atintensity “k” (which is the number of image pixels n(k) having the intensity value “k”), and “L”is the total number
