Our purpose in sharing our current situation is to gain feedback fromcolleagues experienced with projects of this size and type on how to effectively make midstreamcorrections to design-based methods in ways that maintain research and project fidelity. Duringthe 2019-20 academic year, the first year of the project, we created tools and procedures for datacollection and analysis that we piloted in Spring 2020 with the first cohort of students toparticipate in the S-STEM program. With regard to supporting undergraduate students, the planfor this multi-year, grant-funded project is to scale each year, along with increasing the size ofparticipant cohorts, through the fifth and final year of the project.

Antarctica is the main habitat of the penguins. Antarctica as the coldest place onEarth has a very short summer and a very long winter. In winter, the average temperatures rangebetween -20 ◦C in the coastal strip and -70 ◦C in the continent, while in the summer the averagetemperatures range between 0 ◦C along the coast and -35 ◦C in the continent3. The core temperatureof a penguin is about 36.9 degrees Celsius. Most of the penguins swim underwater at around 1.8 to3.1 m/s, but the fastest penguin, Gentoo (Pygoscelis Papua), can reach top speeds of 9.8 m/s

when the substance was at thequasi-equilibrium state.In academia, once a written description of a problem is given or created, the solving of theproblem can be viewed in two stages. Stage I: Formulation of a procedure for solving the problem, wherein the determination of the governing equations and constraints are considered a part of this step. Stage II: Performance or execution of the required mathematical steps to solve the governing equation(s) using the specified constraints for the desired unknown.It is from this problem solving perspective that the forthcoming concept map has beencreated.

Page 2.127.3 Frequency Resolution: The FFT finds coefficients of the harmonic signal at anincremental frequency,∆f, which is determined by the data sampling rate divided by the numberof points acquired. This ∆f can be interpreted as the width of a frequency bin that is centered onfcent. The smaller the width of the bin, the higher the resolution of frequency. It is important tonote that changing the sample size or sampling rate will change the resolution, and that changingsampling rate alone modifies both the Nyquist cut-off frequency and the center frequency.

are measuring digital signals. This is a violation of Nyquist’s first rule.Most scope vendors don’t specify their scope’s bandwidth at the Nyquist frequency (fN) – butsome do. However, it is very common for vendors of waveform recorders/digitizers to specifythe bandwidth of their instruments at the Nyquist frequency. Let’s now see what can happenwhen a scope’s bandwidth is the same as the Nyquist frequency (fN).Figure 4 shows an example of a 500-MHzbandwidth scope sampling at just 1 GSa/s whileoperating in a three- or four-channel mode.Although the fundamental frequency (clock rate)of the input signal is well within Nyquist’s criteria,the signal’s edges contain significant frequency Aliasingcomponents well
expressed, Stokes’theorem can be described by considering a surface S having a bounding curve C. Here, v isany sufficiently smooth vector field defined on the surface and its bounding curve C. It isvery important to emphasize the fact that C is any closed curve in three dimensional spaceand S is any surface bounded by the said curve C. Mathematically this is written as: Page 22.257.4 ∫ (∇ × v) • dS = ∫ v • dx s cIn addition, it is important to note that when one considers only a two-dimensional space,Stokes’ theorem effectively becomes Green’s theorem.Another method of
