A simplified physically-based model for core dam overtopping breach
Engineering Failure Analysis, 2018Based on the breach mechanism of the core dam due to overtopping failure, a simplified physically-based model has been proposed in this study. A hydraulic method was used to predict the initial scour position for high dam.

A physically based model for the electrical conductivity of partially saturated porous media
, 2019Electrical conductivity is one of the most commonly used geophysical method for reservoir and environmental studies. Its main interest lies in its sensitivity to key properties of storage and transport in porous media.

Physical Modeling of Probe-Based Storage
2001 Eighteenth IEEE Symposium on Mass Storage Systems and Technologies, 2001Magnetic disks may be reaching physical performance limits due to the superparamagnetic effect. To close the performance gap between processors and storage, researchers are exploring a variety of new storage technologies [17]. Among these new technologies, probe-based micro-electrical mechanical systems (MEMS) magnetic storage arrays are attractive [3].

This chapter is devoted to the derivation of physical models for hydraulic servo-systems and includes the most relevant dynamic and non-linear effects that are involved in hydraulic servo-systems. The model derivation is based on the physical fundamentals described in Chapter 3 and on first principles.

A physically-based BRDF model for retroreflection
Proceedings of the Computer Graphics International Conference, 2017We introduce an analytical BRDF model tailored to the realistic rendering of retroreflective materials. Though these specially-designed materials are frequently encountered in our daily life, such as high-visibility clothing and traffic signs, their reflectance behaviors are barely analyzed and simulated in a physically meaningful manner in computer ...

A physically based visco-hyperelastic constitutive model for soft materials
Journal of the mechanics and physics of solids, 2019Viscoelasticity is an essential mechanical property of soft materials. Many constitutive models have been proposed to capture this mechanical behavior, but few physically based models were developed due to the challenge to incorporate the micro ...

A physically based model for icicle growth
The Visual Computer, 1993This work in the area of modeling of natural phenomena in computer graphics presents a new, physically based model for the natural process of icicle growth and implements the model creating photorealistic icicle images at the various stages of their growth. The physical model developed here is based on the analysis of the mechanical and thermodynamical

An Object-Based Model in Physics
2022A topological model of the object-based space is represented as a bundle allowing for a complete description of an object by specifying the intensity and rigidity of its properties, and the object itself is represented as a resultant vector. As a case study, an object-based space is constructed that makes it possible to obtain the relations of the ...

A Physically‐Based Model for Rendering Realistic Scratches
Computer Graphics Forum, 2004Abstract Individually visible scratches, also called isolated scratches, are very common in real world surfaces. Although their microgeometry is not visible, they are individually perceptible by the human eye, lying into a representation scale between BRDF and texture.

Fault prognosis based on physical and stochastic models
2016 European Control Conference (ECC), 2016This paper deals with a fault prognosis method based on physical and stochastic models. Health Indicators (HIs) are generated from a bond graph model using analytical redundancy principle, then, the generated HIs are used to assess the current state of the system and to detect the degradation beginning.
