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

key enzyme in NAD+ regeneration, the glycolytic flux shifts from homolactic to mixed acid fermentation with the redirection of pyruvate towards production of formate, acetate, ethanol and carbon dioxide. A mathematical model of the pyruvate metabolism pathway that enhances our understanding of ethanol production was developed from in vivo nuclear magnetic resonance (NMR) time series measurements that describes the dynamics of the metabolites in L. lactis. An S-system model based on the power law representation was able to capture the observed dynamics of the pyruvate metabolism pathway in L. lactis in vivo. The model provides insights into the maximization of selectivity

Do the results imply that we simply have notfaced the problem of how to get the technical core of the curriculum to work synergistically withthe complementary studies component? What does this mean with regards to the ability of ourprofession to protect the public interest?

SaoudIntroductionUndergraduate dynamics is often cited as one of the most difficult courses that engineeringstudents must take because many of the topics are in direct conflict with their perception of theworld around them. Newton‟s laws of motion are fundamental to the study of dynamics andstudents are particularly prone to having misconceptions drawn from their daily life interactionwith moving objects.

fatigue theory is very important to be developed in mechanical engineeringstudents. 1The fatigue strength or test data should be described by the random variables, that is, statisticalapproach. However, for undergraduate program, fatigue test data are typically described bydeveloping Stress (S) vs. average Cycles (N) to failure (S-N) curves. These curves are thefunctions of stress amplitude, mean stress and the average number of cycles at failure. Thefatigue strength of a component is significantly affected by inherent component defects andloading conditions. As such, the material strength design limit is reduced thru the application ofmodification factors, often linked with component stresses thru

Analysis of recent PEOs from 48 programs in 36 institutions (235 PEOs total)suggests an almost complete lack of attention to global competence: the PEOs analyzed includethe words global, international or world less than 7% of the time. The word culture or culturalwas not present.Recently, Jesiek, Shen, and Haller (2012) proposed that the Miville-Guzman Universality-Diversity Scale-Short form (MGUDS-S), originally designed to assess cross-culturalcompetency, can also be used as one method to assess the global competency of engineeringstudents and

, particularly the 1970‗s and 1980‗s, female participation in higher education inMexico was very low. This phenomenon was associated with socio-cultural stereotypes thatestablished Mexican women as mothers and wives and identified them as emotional andaffective, and therefore not ―fit‖ for schooling; this ultimately has kept them from paid workand formal education. Historically the characteristics of Mexican educational institutions havenot only affected the experiences of female students, but also have stressed traditional roles ofwomen and thus present challenges for women who venture into non-traditional fields1. Despitethis, participation of women in higher education in Mexico has increased substantially in the lastthree decades and has nearly

Proponents also argue that S&E fairs enhance students’interest in science and science careers [6, 7] as well as engineering [2].
