Modeling & Analysis Overview The gain scheduling methods of Chapter 1 that were judged to be the more promising and also offering the best background for further development were tested using two different benchmark examples. The first one is an...
A relaxation method for two-phase flow models with hydrodynamic closure law Abstract The present paper is devoted to the numerical approximation of the solutions of a system of conservation laws arising in the modeling of two-phase flows in oil and...
Wave propagation Waves, as summarized in the insightful review by Keller (1979), are disturbances that propagate through space and time, usually by transference of energy. Propagation is the process of travel or movement from one place to another. Thus wave...
FULL-PLANE IMPEDANCE LAPLACE PROBLEM In this appendix we study the perturbed full-plane or free-plane impedance Laplace problem, also known as the exterior impedance Laplace problem in 2D, using integral equation techniques and the boundary element method. We consider the problem...
HARBOR RESONANCES IN COASTAL ENGINEERING In this chapter we consider the application of the half-plane Helmholtz problem described in Chapter III to the computation of harbor resonances in coastal engineering. We consider the problem of computing resonances for the Helmholtz...
Towards design stability margins estimations using Chetaev functions Definition Formally, stability is a concept that characterizes the equilibrium positions of a system22 . Imagine what would be the motion of the particles of mass m if they were slightly deviated...
Rotorcraft aeromechanical system bond graph Rotor-airframe model using multibody dynamics A central coupling to be modeled in rotorcraft dynamics is the rotor-airframe one. This coupling is at the heart of the most classic aeroelastic phenomenon in helicopters such as ground...
Energy supply by nuclear power plants constitutes, nowadays, one of the main technologies adopted in this industrial sector. The treatment and isolation of the radioactive waste generated by activities based on nuclear energy have become fundamental concerns. In principle, more...
The study of brain mechanisms that underlie cognition (perception, motivity, language and memory) is a research field commonly referred to as cognitive neuroscience. In this domain, an important issue for further understanding of the brain is to establish the connection...
Alice in cryptoland I will tell you a typical day for Alice. To go to work, Alice takes public transport using her electronic pass. Upon arriving at work, she opens her office’s door with her identification badge. After saying hello...
