work-horse of industry and these machines have what is calledthe “rotating magnetic field”. We consider a sequence a-b-c and a symmetric distribution of the phasesby 1200 electrical degrees each in space and around the air gap. The basic three-phase machine will havethree coils, a coil per phase, that have the following terminals: a a’ b b’ c c’These coils are excited by a time dependent sinusoidal alternating current producing a sinusoidalmagnetomotive force (mmf) wave at the center of the magnetic axis of a particular phase. Therefore thethree-space sinusoidal mmf waves are displaced 1200 electrical degrees in space. Notice that the coils

with the slave, it would count it in its list of users. This also resulted in double- counting of slaves in a scatternet. Figure 4 illustrates the master/slave connectivity of concluding remarks 1 & 2. Note that with proper handling, Master A and Master B should only detect two slaves each making a total of four slaves. This leads to an analytical report of two masters, each with two slaves - a total of 6 devices altogether. However, as a result of the Master-Master problem (where each master detects the other as a slave in its network), each one will report three (2 slaves + 1 other master). In addition, without the slaves breaking their connections appropriately, slaves 2 & 3 will each appear in the other network as

In typical undergraduate engineering applications,Type A uncertainty is related to random errors, and Type B uncertainty is related to systematicerrors. The two types of uncertainties can be combined using the usual rule for combiningvariances due to independent sources of error. Since the two types of uncertainty, UA and UB,must be independent, the combined uncertainty is U C2 = U A 2 + U B2 (1) A measurement and its uncertainty, whether either type or the

Thecross in the center is used for X and Y alignment. The outer crosses are used for rotationalalignment. The outer crosses were located as far from the center as the alignment tool allows.While sacrificing resolution, the ease, low cost and speed with which mask sets can be modified ordesigned from scratch is an incredible advantage. This advantage allowed rapid development ofworking devices. The possibility of an advanced course where the students design and test theirown mask sets can also be realized. (a) (b

they have learned. This reflective process is an essential factor inthe emergence of expertise. Experts are often characterized as having three distinctive kinds ofknowledge: (a) declarative knowledge ("knowledge that"), (b) procedural knowledge ("how toknowledge"), and (c) metacognitive knowledge with its attendant processes of self-monitoring,agency, reflection. Declarative knowledge refers to the kind of knowledge typically learnedfrom textbooks--facts and concepts. Procedural knowledge refers to being able to do something,be it writing code, proceeding through analysis and design, using a software process approach, orwriting a paper about ethics in the software industry.
