, cross-sectionalarea, and conductivity, respectively. Therefore, this “Top-Down” approach would predict that asthe length is decreased to a 3-D nanoscopic resistor, as shown in Figure 1 on the right, itsresistance would approach zero ohms. However, it is now well known that the conductance fornano-scale ballistic conductors is quantized in multiples of q2/h ≈ 1/(25kΩ)1, where q is theelectron charge (1.6 × 10 C) and h is Planck’s Constant (6.63 × 10 J-sec). For thisreason, the resistance of the simplest 1-D nanoscopic device would approach h/q2 ≈ 25kΩ (notzero ohms). A=Wt A=Wt L L

as transceivers, utilizing high performanceDAC/ADC hardware that supports a wide spectral bandwidth when coupled with a specializedwideband RF front end daughterboard. It should be noted that high-Q, narrow-banddaughterboards are also available for ISM bands.The hardware architecture of the USRP includes a FPGA for digital up/down-conversion to/fromthe DAC/ADC for the IF signal to/from the RF daughterboard, respectively. This techniqueallows for the highest resolution ADC/DAC conversion between the baseband and IF signals.Shown below in Figure 2 is the generalized architecture of the USRP series. The FPGA can alsobe used to implement additional DSP functionality, however this may reduce FPGA digitalsample rate conversion performance.There

equivalency will be described in terms of coursematerials, hands-on labs, student support and assessment. The same course materials were usedin both on-site and online versions. To have the same hands-on lab experience, studentspurchased an affordable lab kit to set up a home lab and perform the same lab exercises as in anon-campus lab. Piazza, an online Q&A discussion forum, was used to provide students withprompt answers to their questions, equivalent to but more convenient than on-campus officehours. Finally, to give the same assessment to online students as to on-site students, ProctorU, anonline proctor service, was used in the final exam.The online course was first piloted in summer 2014 with 128 students enrolled. Since then, anadditional

An equation from the Melt Wear Control of Metals in High-Speed Sliding Contactspublication by then Doctoral Candidate Edin E. Balic was referenced in order to derive Equation 13,which calculates the maximum temperature rise at the exit of a metal coming in contact with anothermetal. T = 2qdkπPe α + TO (13)where d is the half-length of the armature contact path, q is the power per area, k is the thermalconductivity, Pe is the Perclet number, and α is the thermal diffusivity of the rail material.

intriguing adjustment to STEM curricula, whichrenovates out of class activities for the reality of the search engine era.Another approach for hierarchical technology enabled STEM delivery is the Online ClassroomModel (OCM). The purpose of the OCM is the guidance of the design, implementation, andassessment of online education systems utilizing four learning theory oriented components andthree human–computer interaction principles. This model promotes augmented face-to-faceinteractions by offering several features, such as collaborative multimedia presentation, virtuallaboratory, social and collaborative Q&A community, and a robust communication framework tothe online classroom 8.
