Using this matrix, a better feedback can be obtained. However, sometimes it isrecommended to derive a holistic rubric from the detailed rubric. A holistic rubric allows you toasses different skills of the students for accreditation purposes once or twice rather than on eachexperimental session. For example, sometimes writing skills are more important than designingan experiment or student competencies with laboratory equipment. Certainly, to assess all of thelaboratory skills in each experimental session will

An appropriate assessment is for sure needed.1.1 Example 1There are many gas power cycles, such as Carnot cycle, Otto cycle and Diesel cycle. In mostcases, the textbook discusses each of them and shows the process in a P-v and/or a T-s diagram.The diagrams can help the student to understand and memorize these cycles. However, thestudents may become confused to remember these curves because all the curves are quite new tothem. To help the students in learning these cycles, it is seen that all the well-known reversiblecycles (Carnot, Ericsson and Stirling) can be integrated into one T-s diagram (or a P-v diagram).Figure 1 shows the individual diagrams of the

) codes demonstrate high performance capabilities, arbitrarily close to the Shannon limit,and are becoming feasible with today’s processing technology [10]. LDPC codes are founded onbasic linear-algebra principles. In this paper math is performed in the binary subspace of real-numbers, and hence addition and multiplication are performed in base 2, e.g. addition becomesthe XOR operation, and multiplication becomes the AND operation. LDPC codes utilize a sparsebinary parity-check matrix, H, with dimensions M×N. Matrix H can be either regular, meaningthat there are a specific number of 1’s per row and column, or irregular, in which there may ormay not be a constraint on the number of 1’s.

empirical formula for volumetric materialremoval rate in electric discharge machining22, I MRR = K 1.23 Tmwhere MRR is metal removal rate in mm3/s; K is constant of proportionality equal to 664; I isdischarge current in A, and Tm is melting point of work metal in ºC. While the published formulaapplies to a material removal process only, due to the nature of the process it can be extrapolatedthat the same process variables (I, and Tm) apply for carbon nanotube manufacturing. Theempirical material removal rate formula is to be augmented as the results dictate. Based on thecurrent prices of carbon, and the cost of electrical energy as found from students’ electrical bills,an economical analysis is to be
