Constitutive modeling based on continuum mechanics theory has been a classical approach for the mechanical responses of materials. However, when constitutive laws are unknown or defects and/or high degrees heterogeneity present, these models may become inaccurate. In this work, we propose to use data-driven modeling, which directly utilizes high-fidelity simulation experimental measurements pre...

Introduction: In vitro dosimetric verification prior to patient treatment plays a key role in accurate and precision radiotherapy treatment delivery. Since the human body is a heterogeneous medium, the aim of this study was to design a heterogeneous pelvic phantom for radiotherapy quality assurance. Material and Methods: A pelvic phantom was ...

This paper addresses a process in which we combined educational guidelines (EG) from heterogeneous sources in one set of coherent computable statements to support dynamically generated and precisely tailored patient education material. The Guideline Interchange Format (GLIF), predicate logic and decision tables were assessed. An extended formalism of GLIF was applied to break up composite sente...

Hierarchical modeling refers to the modeling of parts with solid geometry, material composition, and possibly distributions of properties at multiple scales. Typical solid and heterogeneous models represent geometry at one scale but do not contain geometric information about features at scales that are orders of magnitude smaller. In this paper, the related topics of heterogeneous and hybrid mo...

Green’s function, an analytical approach in inhomogeneous linear differential equations, is the impulse response, which is applied for deriving the wave equation solution in composite materials mediums. This paper investigates the study of SH wave’s transmission influenced by concentrated point source disturbance in piezomagnetic material resting over heterogeneous half-space. Green function ap...
