Abstract. The presentation under the title “A Glance on Data Analytics and Its Applications” starts
with an introduction to natural and artificial intelligent system as the baseline for introducing the main
concepts of data itself and data analytics. Then illustrates how analytics thinking and holistic thinking
may conceptually lead to generating insight and ends up with actionable decision. The rest of the
presentation highlights the eco-system of data analytics techniques and tools for applying statistics,
machine learning and visual analytics on data to generate insights for decision and policy makers. The
concluding part presentation explains several applications of data analytics and AI techniques in
different sectors to express the role of data analytics in future.

Abstract. Natural convection is a phenomenon in which the fluid motion is driven by buoyancy forces,
caused by density differences due to temperature variations in the fluid. Developing new models of
heating and cooling systems is the common method to improve quality of product in industries. As a
main element of these systems, we can note working fluids that have the duty to transfer heat energy
from one place to another one. The recent developments in technology require an innovative revolution
in the field of heat transfer. Nanofluid is a developed fluid that has better potential for using in heating
and cooling systems. Nanofluid is a kind of heat transport medium containing nanoparticles less than
100 nm which are consistently and steadily dispersed in a base fluid. Hybrid nanofluid as a next
generation of nanofluid is developed which are having high thermal conductivity compared to mono
nanofluid. Hybrid nanofluid refers to the formation of two or more nanoparticles in a base fluid. A
numerical study is conducted to investigate the transport mechanism of natural convection in a cavity
filled with hybrid fluid containing alumina Al203 and copper Cu nanoparticles are dispersed in water
as a base fluid. A comprehensive mathematical model is developed, which is solved using the Galerkin
weighted residual along with finite element technique. The influences of the solid volume fraction on
the convective flow, as well as the effect of the inclination angle of the sloping wall on thermal
performances were examined. The streamlines, isotherm plots and the variation of the average Nusselt
number are presented and discussed.
