Overall,responses to the questions were positive. The questions, with a summary statement, follow. Q: Describe the ways in which you found the VR models effective for your learning and provide examples Students’ responses described their learning experience with the VR models as fun, morerealistic, engaging them in their learning, and providing them with visualization enhancements.

(10c)The “discriminant factor”, for the cubic polynomial D, will dictate the type of solutionspossible8. For D negative, all roots are real; while for D positive, only one root is real while theother two are complex. If D is zero, there will be repeated roots.

easily implemented using an I/Q modulator.Only two I values and two Q values are needed, and this gives two bits per channel. There arefour states for QPSK. It is, therefore, a bandwidth-efficient modulation compared to BPSK andpotentially twice as efficient.Quadrature Amplitude ModulationQuadrature Amplitude Modulation (QAM) is a method for transmitting two separate (anduniquely different) channels of information using a single carrier. The two modulation inputs(analog or digital) are applied to two separate balanced modulators, each of which is suppliedwith the sin or cos carriers. That means one of the modulators is supplied with the sin carrier andthe other with the cos carrier.The outputs of both modulators are algebraically summed and

frequency.Quantile Plots4Suppose the fraction, f, of a sample is less than or equal to the value q(f). q(f) is termed thequantile for that fraction. For a particular probability distribution, q(f) can be determined for anyvalue of f and any sample size. It is expected that the experimental quantile (i.e. the quantile forthe data obtained in the experiment) will be very similar to the theoretical quantile if the datafollow the theoretical distribution closely. Put another way, if the experimental data is plottedagainst the theoretical quantile the points would be expected to lie along a straight line. If true,then the sample is considered to be normally distributed. A quantile plot may be constructed asfollows:1. Order the experimental data xi from

PSCAD also allows userse to plot different quantities onthe same graph. This will help students to compare different quantities at the same time. Forinstance, in the current experiment they can compare the instantaneous voltage waveforms on SGand Avista side on the same graph. Figure 3 shows P and Q meters that allow students tomeasure both active and reactive power. Since the on-campus students make use of the two-wattmeter method, a similar method is set up in PSCAD for outreach students to use. Figure 3shows the readings of two wattmeters from two

In the analysis the core of the reactor was split into ten sections axially and five sectionsradially. By knowing the power in each of the section as well as the area and number of pebbles,the heat flux was found for each section using the equation. q" = h ( Tsurface − Tbulk ) (7) The pebble surface temperature Tsurface was obtained from the pebble heat transfer model[27] which treated the pebble as a composite material. Using above equations (1)-(7) the heattransfer rate between pebble and the coolant (helium gas) was

It is impossible to learn these conceptsin a short period of time. Printing initial concepts on the Z-402 3-D printer was chewing up toomuch time (instructor, student and printer). When students made modifications to the initialgeometry, the changes were difficult to incorporate into CAD geometry and subsequent 3-Dprints were usually not much better than the initial ones.

tomeasure any AC fields in empirically observed B-dot coil resonance range of 250 to 400 kHz. The next step for the students in their probe design was to estimate themagnitude of the magnetic field at the center of the wire loop ( i.e. z = 0 ). In referenceto the loop depicted in Figure 2, the field at z = 0 can be estimated by using the Biot-Savart Law . Figure 2. Use of the Biot-Savart Law to calculate the axial magnetic field along the longitudinal axis of a wire loop carrying an elemental current IdL [ 1 ]. The Biot-Savart Law states that the field at a distance R from a circular loop ofwire is given by [ 1 ] B =µ I sin Q * dL / 2 R^2 (4)where u is the magnetic permeability
