A simple model of above threshold ionization
A simple model for above threshold ionization is presented in this work. It is based on modeling the pulsed laser beam involved in ionization as a cylinder consisting of elementary cells whose volumes are very small compared to the pulse volume. A cell is occupied by a number of photons determined …

Evaluation of a Simple Model for the Acoustics of Bat Swarms
… To characterize the acoustics of bat swarms, a simple model of the acoustically relevant properties of a bat swarm has been set up and evaluated. The model contains only four parameters: bat spacial density, biosonar beamwidth, duty cycle, and a scalar measure for the smoothness of the flight …

A portfolio approach for the TESOBONO problem in Mexico during 1994: A simple model
During 1994 domestic and foreign investors in Mexico increased the share of TESOBONOS in their portfolios when they perceived the possibility of a future devaluation of the Mexican peso or, in other words, the abandonment of the controlled floating exchange rate regime. This work finds that both …

Wave induced response of sea floor deposits : a simple model for sands and nonlinear analysis by FEM
… is assumed to be a saturated porous medium modelled by a two-phase system. The theory of mixture is used to derive the coupled governing equations. A simple material constitutive model is proposed based on the generalized plasticity-bounding surface formulation. Some comparisons of the model …

A simple model for the depolarizing effects of rain and ice on earth satellite links in the 10 to 30 GHz frequency range
… in depth using a rigorous multiple scattering model. This relationship for rain is expressed in the form of a simple function similar to that used by the CCIR. Prediction accuracy using this simple model is quantified by comparisons to measured data and other model values. The impact of …

Feynman Diagram Models of Daughter Regge Trajectories
The Van Hove model of Regge poles is used to study daughter trajectories of bosons in scalar meson-scalar meson scattering and of fermions in backward pion-nucleon scattering. Both the simple model with bare propagators and a generalized model that includes propagator self-energy insertions are …

Geometrical Representation, Processing, and Coding of Visual Information
In the second case, we use a simple model to show that the information rates of the POF are equivalent to the information rates of the scene around it.

Buckling and postbuckling analysis of delaminated beams under compressive loads
… of a delaminated beam. In the first part, a simple model for predicting the linearized buckling of a composite beam with multiple delaminations is described. The study employs an energy method and arbitrary assumed displacements. Lagrange multipliers are used to enforce the kinematic …

Dynamics of nanoparticle combustion
… temperature results suggested that heat transfer models currently used for burning nanoparticles may significantly overestimate heat losses during combustion. By applying conventional non-continuum heat transfer correlations to burning nano-aluminum particles, the observed peak temperatures, which …

Neutron Compton scattering from hydrogen and perovskite oxide interfaces
… the techniques of impurity theory. Firstly, a simple model of a cuprate-manganite interface is proposed to explain several recent experiments. By applying the idea that the metallicity of the manganite spills out into the cuprate, we provide a theoretical interpretation of the unusual …
