Physical Phenomena

Fractional calculus (FC) is a valuable tool in the modeling of many phenomena, and it has become a topic of great interest in science and engineering. This mathematical tool has proved its efficiency in modeling the intermediate anomalous behaviors observed in different physical phenomena. The Meissner–Ochsenfeld effect describes the levitation of superconductors in a nonuniform magnetic field if they are cooled below critical temperature. This paper presents analytical solutions of the fractional London equation that describes the Meissner–Ochsenfeld effect considering the Liouville–Caputo, Caputo–Fabrizio–Caputo, Atangana–Baleanu–Caputo, fractional conformable derivative in Liouville–Caputo sense and Atangana–Koca–Caputo fractional-order derivatives. Numerical simulations were obtained for different values of the fractional-order.

Fourier analysis is a powerful tool for many problems, and especially for solving various differential equations of interest in science and engineering. In the present paper since the utilization of Zadeh’s Extension principle is quite difficult in practice, we prefer the idea of level sets in order to construct a fuzzy-valued function on a closed interval via related membership function. We derive uniform convergence of a fuzzy-valued function sequences and series with level sets. Also we study Hukuhara differentiation and Henstock integration of a fuzzy-valued function with some necessary inclusions. Furthermore, Fourier series of periodic fuzzy-valued functions is defined and its complex form is given via sine and cosine fuzzy coefficients with an illustrative example. Finally, by using the Dirichlet kernel and its properties, we especially examine the convergence of Fourier series of fuzzy-valued functions at each point of discontinuity, where one-sided limits exist.

The University

For over twenty years, the University of Waterloo’s Faculty of Engineering has been running outreach programming directed at elementary youth (ages 6 to 14) through its Engineering Science Quest (ESQ) summer camp program. All the activities are designed to be hands-on with the primary goal to increase participant’s interest in Science, Technology, Engineering and Math (STEM). The camp develops themes, such as ‘Outer Space’ to help motivate activity development and provide practical examples to participants.In 2010, the directors of ESQ modified the approach to develop camp outreach activities to ensure they were hands-on engaging activities related to science and engineering but also paid consideration to ensuring a secondary set of goals were met that considered the cognitive development of the children in the camp. The result was the development of hands-on outreach activities that engaged the participants in multiple ways.The motivation behind the development of outreach activities with these secondary objectives in mind were based on observation of past successes and working knowledge of the target audience.It is concluded that in order to make truly engaging and effective programming for elementary aged youth; activity developers should develop hands-on activities that incorporate both the interests of youth and their appropriate cognitive development stage. Using these methods in activity development will lead to an increase in success and a stronger impact of the programming.

Gifted Girls

Despite having the raw ability to pursue careers in science and engineering, gifted girls often shy away from such careers. Here, the authors explore two explanations for this puzzling phenomenon. Specifically, they argue that exposure to (a) negative stereotypes about women’s intellectual abilities and (b) stereotypes about scientists as “nerdy,” eccentric loners may undermine gifted girls’ confidence in their ability to succeed in science and engineering, their sense of belonging in these fields, and—ultimately—their interest. The authors also suggest evidence-based strategies for inoculating girls against these stereotypes and boosting their interest in science and engineering.
