The Placement of Electronic Circuits Problem: A Neural Network Approach
The goal of this paper is to apply the Continuous Hopfield Networks (CHN) to the
Placement of Electronic Circuit Problem (PECP). This assignment problem has been expressed
as Quadratic Knapsack Problem (QKP). To solve the PECP via the CHN, we choose an energy
function which ensures an appropriate balance between minimization of the cost function
and simultaneous satisfaction of the PECP constraints. In addition, the parameters of this
function must avoid some bad local minima. Finally, some computational experiments solving
the PECP are include
Reducing drag on a flat plate subjected to incompressible laminar flow
The idea behind this work comes from the question: What is the impact of plate corrugations on drag? In this context, a numerical study of laminar incompressible flow over a flat plate and over corrugated plates is carried out. Numerical analysis is performed for low Reynolds numbers (Re= 10, Re = 50, Re = 100, Re = 500, Re =1000) using the computational fluid dynamics (CFD) software ANSYS FLUENT. Simulations results are compared to each others and with those of the reference plate (flat plate (figure 4a)). Comparisons are made via drag coefficient Cd. This work is the beginning of a study that evaluates the impact of corrugations on drag reduction on a flat plate
