(2017-07-05)Smart devices have unique security challenges and are becoming increasingly common. They have been used in the past to launch cyber attacks such as the Mirai attack. This work is focused on solving the threats posed to and ...
-
It is easy to “ping” a remote computer from one’s own to determine the time delay between them, but estimating the latency between two remote hosts is much less trivial. This problem has various applications: social ...

(2012-07-16)Gas turbine engines are the main propulsion source for world wide aviation and are also used for power generation. Even though they rely mainly on fossil fuel and emit climate active gasses, their importance is not likely ...
-
(2019-03-20)The aim of this study was to employing high-fidelity computational fluid dynamics to investi-gate and quantify the turbulent flow effects for incompressible, isothermal fluid flows, in the near wall region of unstructured, ...
-
(2019-03-20)Methods for transferring heat through convection are highly variable and numerous in application. Still, the principle mechanisms that drive convective heat transfer can be reduced down to thermal conditions, fluid properties, ...
-
(2014-07-24)Turbulence is the most common state of fluid motion in both natural and engineering systems. Many real world applications depend on our ability to predict and control turbulent processes. Due to the presence of both ...
-
(2018-10-25)The interaction of turbulence with shock waves, while very common in nature and engineered systems, is a very difficult problem from a theoretical, numerical and experimental perspective. A main challenge comes from the ...
-
(2014-04-29)The incompressible viscous flow past a sphere is investigated numerically at moderate Reynolds numbers. Periodic vortex shedding happens at these Reynolds numbers. The primary objective is to identify the surface signature ...
-
(2016-04-13)Turbulence in high-speed flows is an important problem in aerospace applications, yet extremely difficult from a theoretical, computational and experimental perspective. A main reason for the lack of complete understanding ...
