conclusions lack of difference in self-esteem of disabled people in different degrees of disability and in both men and women suggests that disabled people should not be presumed to have low self-esteem, and their different aspects of life should be attended to, just like others. furthermore, studies should be designed and implemented based on psychological, social and environmental factors tha...

The article discusses the pedagogic advantages of structural analysis software based on nonlinear dynamic structural theory, in contrast to software most commonly used in architectural education which is based in linear static theory. Traditionally, structural education in both architecture and engineering has considered nonlinear dynamic theory to be an advanced-level tool, reserved for gradua...

Nonlinear wave motion in dispersive media is solved numerically. The model applies to laser propagation in a relativistic plasma. The latter causes, besides dispersion, nonlinear effects due to relativistic mass variation in the presence of strong laser pulses. A new variant of the Gautschi–type integrator for reducing the number of time steps is proposed as a fast solver for such nonlinear wav...

The entropically based nonlinear Adam-Gibbs equation is discussed in the context of phenomenologies for nonlinear enthalpy relaxation within the glass transition temperature range. In many materials for which adequate data are available, the nonlinear Adam-Gibbs parameters are physically reasonable and agree with those obtained from linear relaxation data and thermodynamic extrapolations. Obser...

In this paper we propose a new general framework for the application of the nonlinear finite element method (FEM) to nonrigid motion analysis. We construct the models by integrating image data and prior knowledge, using well-established techniques from computer vision, structural mechanics, and computer-aided design (CAD). These techniques guide the process of optimization of mesh models. Linea...

We consider the quantum field theory of two bosonic fields interacting via both parametric ~cubic! and quartic couplings. In the case of photonic fields in a nonlinear optical medium, this corresponds to the process of second-harmonic generation ~via x (2) nonlinearity! modified by the x (3) nonlinearity. The quantum solitons or energy eigenstates ~bound-state solutions! are obtained exactly in...

In this paper, we describe a dynamic control algorithm that allows a humanoid character to swim through a fluid. The swimming is physically-based, whereby the character applies simulated muscle forces in order to drive the body through the motions of a breaststroke. The interaction between the moving body parts and a fluid dynamics system results in drag forces that cause the swimmer’s body to ...

Physically-based animation techniques enable more realistic and accurate animation to be created. Such approaches require the creation of a complex simulation model that, for computer graphics applications, can efficiently produce realistic-looking animations. We present a process to automatically create animatable nonconforming hexahedral finite element (FE) simulation models of facial soft ti...
