Development of next-generation electronic devices calls for the discovery quantum materials hosting novel electronic, magnetic, and topological properties. Traditional structure methods require expensive computation time memory consumption, thus a fast accurate prediction model is desired with increasing importance. Representing interactions among atomic orbitals in material, Hamiltonian matrix...

The present numerical work deals with the optimization of micro-channel heat sink using irreversibility analysis. nanofluid Al2O3-water different nanoparticles concentration and temperature-dependent property is chosen as a coolant. flow considered fully developed, steady, laminar in constant cross-section circular channels. Navier-Stokes energy equations are solved for single-phase total mass ...

This paper presents a machine learning methodology to improve the predictions of traditional RANS turbulence models in channel flows subject strong variations their thermophysical properties. The developed formulation contains several improvements over existing Field Inversion Machine Learning (FIML) frameworks described literature. We first showcase use efficient optimization routines automati...

Humans implicitly rely on properties of the materials that make up ordinary objects to guide our interactions. Grasping smooth materials, for example, requires more care than rough ones, and softness is an ideal property for fabric used in bedding. Even when these properties are not purely visual (softness is a physical property of the material), we may still infer the softness of a fabric by l...

It is difficult to obtain high quality samples of natural material covering a range of densities and degree of cementation, so study on the sample preparation techniques with similar mechanical properties of natural samples are very important. Experiments were carried out to study the effects of cementation of different materials on the mechanical properties of calcareous sand, e.g., the effect...

Azobenzene photoalignment materials are highly effective for liquid crystal alignment with high sensitivity and rewritability. A strong relationship between relative humidity and the alignment quality of a thin layer of azobenzenesulfonic dye has been investigated, where the photoinduced phase retardation, order parameter, and anchoring strength of the alignment layer are influenced dramaticall...

During the fall semester of the 2005-2006 academic year, I decided to try to produce some scale models of structural systems out of rubber. I had in mind to use these models to demonstrate structural behavior to undergraduate students, thinking that seeing models deform under load would be far more convincing than the standard line diagrams of deformed shapes that we typically use in engineerin...
