Many research reports indicate that class attendance is an essential school factor which affects
students’ grades and performance in a course, grade point average, progression in college, and
subsequently graduation. In this pilot study, we collect sample attendance records of courses
from faculty members, summarize, and analyze them. We use statistical tools to determine
sample statistics. Furthermore, we examine whether there are any significant differences
between class attendance rates in the mathematics classes. Using hypothesis testing, we
conclude that indeed there are significant differences between class attendance rates.

Mathematical Modeling and Analysis of Nanofluid Flow

“Mathematical Modeling and Analysis of Unsteady Nanofluid Flow” will provide the
fundamental understanding of unsteady convective heat and mass transfer phenomena in
complex nanofluids. Nanofluids are suspensions of nanoparticles in fluids that show significant
enhancement of their properties at modest nanoparticle concentrations. The governing
equations for nanofluid flow in unsteady mixed convection are system of coupled partial
differential equations, which are highly nonlinear in nature. Though the novel properties of
nanofluids make them potentially useful in many industrial applications, transportation, as
well as food industry, the mathematical research in this area is still in rudimentary level. The
increasing emphasis on interdisciplinary studies in this modern era, demands study of more
scientific and mathematical aspects of nanofluid phenomena. The project will focus on
developing mathematical modeling and analysis of nanofluid in axisymmetic and three
dimensional flows. We shall obtain a new self-similar solutions for the unsteady mixed
convection nanofluid flow in axisymmetric bodies. (A solution is called self-similar if a system
of partial differential equations can be reduced to a system of ordinary differential equations.)
