Studies on chiral spectroscopy have recently demonstrated strong enhancement of light-matter interaction in the near-field Mie resonance high-refractive-index dielectric nanostructures by studies spectroscopy. This situation has motivated researchers to demonstrate effective photosynthesis under a beyond circularly polarized light (CPL) as source. However, effectivity for not been clearly demonstrated. One major challenge is experimental difficulty evaluating enantiomeric excess trace amount...
Convolution neural networks (CNNs) have proven effectiveness, but they are not applicable to all datasets, such as those with heterogeneous attributes, which often used in the finance and banking industries. Such datasets difficult classify, date, existing high-accuracy classifiers rule-extraction methods been able achieve sufficiently high classification accuracies or concise rules. This study aims provide a new approach for achieving transparency conciseness credit scoring attributes by...
We present a design procedure for symmetrically laminated composite structure with GA (Genetic Algorithm) and finite element analysis.Design variables to enhance the rigidity of are number laminae, fiber orientation stacking sequence.Here, is selected among some prepared angles from manufacturing viewpoint.In conventional based on an objective function calculated by costly analysis.Consequently, it quite time consuming unpractical.In this paper, minimize displacement at point in structure,...
Health monitoring system equipped with blood extraction pump is one of the important problems for new medical technology to support advanced age society.In this paper, a piezoelectric actuator was proposed increase volumetric change in pump.We devised geometry some slits that allows stretching and contracting deformation in-plane direction create large deflection outof-plane direction.Focusing on disc-type bimorph plate slits, deformations under static electric load have been analyzed by...
Multiscale Modeling for heterogeneous media such as fiber or particulate reinforced composite materials and porous is one of the recent topics in computational mechanics science. Homogenization technique has been studied used micro-macro bridging under conditions periodicity microstructures uniformity macroscopic field. However, these two make evaluation microscopic stresses using homogenized model useless real applications, because with high gradient at interface, edge surface well stress...
Deterioration in heat transfer to supercritical water is numerically studied using a k-ε model. Physical properties are treated as variables and calculatd from the steam table library. The numerical result agrees with experimental data of Yamagata et al. [Trans. JSME, 38-2(1972)]It found that heat-transfer deterioration caused by two mechanisms depending on flow rate. In case large rate, reduced near wall where fluid locally changed due flux. small buoyancy force flattens velocity...
This study describes the influence of structural deviation in a microstrip patch antenna on millimeter wave performance through use an electromagnetic field simulator. We divided into two deviations: uneven and tapered. The resonant frequency was shifted to low region by deviation. also found that tapered had small effect frequency, return loss improved
The experimental results of fatigue at low stress levels around the limit have large scatter. For design structures and machines, it is important to evaluate scatter decide margin. In this paper, statistical method proposed. proposed method, decided with considering distribution strength. Because each data transformed into normalized strength, has advantage point that strength can be found by relatively small samples. Using computer system margin for developed. system, S-N curve are obtained...
In the strain measurement under tensile testing by digital image correlation (DIC) method, error factors were investigated including sprayed texture, laser processing and chucking. It was shown that density of texture influential on value. Instead providing manually, a spraying apparatus developed, which could provide higher quality for DIC measurement. Finally, influence uncertainty parameters size location holes, specimen width chucking length numerically. The stepwise limited sampling...
In the tensile test of a flat plate with many holes, quantification possible errors m strain measurement by DIC was investigated. Large scattering seen, but no significant difference in seen between aligned and misaligned arrangement holes. An influence texture for on strains also found to be negligible.
This paper presents a numerical study on trabecular bone of human lumbar vertebra by using the homogenization method to predict macroscopic properties. Series set micro-CT images healthy and osteoporotic vertebral is used in this digital image-based modeling technique develop microstructure model. The homogenized properties that include Young's moduli shear was obtained investigate change degree anisotropy bone. Then, comparison between predicted experimental result performed Keyak discussed.
The α and β phases of In 2 Se 3 are attractive thermophotovolβtaic (TPV) materials. For example, they have a direct transition an optimal bandgap for TPV systems. We investigated about the influence growth conditions on crystal forms In-Se prepared by vapor transport. Firstly, only bulk was encapsulated in quartz ampoule crystals were grown Hollow hexagonal cylinders that approximately 10 μm diagonal dimension obtained. They identified as mixed phase XRD. Secondly, deposition surface...
In the use of dentalimplant, a conebecm CT will be frequently utilized to capture 3D structure af hmnan mandible. However, question arises concerning accuracy conebeam images not only for cortical bone but also trabecular bone. this study, comparison between conebearn and micro has been carried out same human mandible by means finite element stress analysis. The position, angle depth single implant were determined thickness distance blood vessels. Then, numerical results in coincidence CT,...
