Oscillation of separation shock wave ahead of forward-facing steps.

Periodic Wave Shock solutions of Burgers equations

In this paper we investigate the exact peroidic wave shock solutions of the Burgers equations. Our purpose is to describe the asymptotic behavior of the solution in the cauchy problem for viscid equation with small parametr ε and to discuss in particular the case of periodic wave shock. We show that the solution of this problem approaches the shock type solution for the cauchy problem of the in...

Three steps ahead

We study a variant of the repeated prisoner’s dilemma with uncertain horizon, in which each player chooses his foresight ability; that is, the timing in which he is informed about the realized length of the interaction. In addition, each player has an independent probability to observe the opponent’s foresight ability. We show that if this probability is not too close to 0 or 1, then the game a...

A Few Steps Ahead to Select ACE2 in Pediatric COVID-19 Treatment: A Review of Literature

This review study aimed to examine the relationship between Coronavirus (COVID-19) and its uses in renin-angiotensin-aldosterone system (RAAS) to infect the patient using the related studies in this regard. Finally, the logical method of using the related medicine, and the benefits and harms of using these Medications will be indicated in the treatment of novel coronavirus. It is hoped that a s...

Oscillation Control of Aircraft Shock Absorber Subsystem Using Intelligent Active Performance and Optimized Classical Techniques Under Sine Wave Runway Excitation (TECHNICAL NOTE)

This paper describes third aircraft model with 2 degrees of freedom. The aim of this study is to develop a mathematical model for investigation of adoptable landing gear vibration behavior and to design Proportional Integration Derivative (PID) classical techniques for control of active hydraulic nonlinear actuator. The parameters of controller and suspension system are adjusted according to be...
