abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

The effect of the slit length on acoustic transfer impedance micro-slit plates (MSPs) is investigated in linear and non-linear regime for a specific geometry. This geometry inspired by slits obtained cutting bending plate. MSPs are with arrays slit-shaped perforations, width order viscous boundary layer thickness. Impedance tube measurements two accurately manufactured compared to numerical sol...

Based on the differential transformation method, a semi-analytical solution is developed for free vibration and modal stress analyses of variable thickness two-directional functionally graded circular plates with restrained edges, resting on elastic foundations. Variations of the material and geometry parameters are monitored by five distinct exponential functions. The presented non-dimensional...

This article comprehensively investigates the thermal performance of a ternary hybrid nanofluid flowing in permeable inclined cylinder/plate system. The study focuses on effects key constraints such as geometry, medium, and heat source/sink distribution features nanofluid. present work is motivated by growing demand for energy-efficient cooling systems various industrial energy-related applicat...

[1] The geometry and properties of the interface of the Cocos plate beneath central Mexico are determined from the receiver functions (RFs) utilizing data from the Meso America Subduction Experiment (MASE). The RF image shows that the subducting oceanic crust is shallowly dipping to the north at 15° for 80 km from Acapulco and then horizontally underplates the continental crust for approximatel...

We report on a type of linear zone plate for nanometer-scale focusing of hard x rays, a multilayer Laue lens (MLL), produced by sectioning a multilayer and illuminating it in Laue diffraction geometry. Because of its large optical depth, a MLL spans the diffraction regimes applicable to a thin Fresnel zone plate and a crystal. Coupled wave theory calculations indicate that focusing to 5 nm or s...

We present a generalization of thin-plate splines for interpolation and approximation of manifold-valued data, and demonstrate its usefulness in computer graphics with several applications from different fields. The cornerstone of our theoretical framework is an energy functional for mappings between two Riemannian manifolds which is independent of parametrization and respects the geometry of b...

In this study, the effect of tool pin length on friction stir lap welding 430 and 304 stainless steels has been investigated. The thermal history interface was measured by thermocouple. interfacial macro- micro-structures under different lengths were analyzed via optical microscope scanning electron microscope. Also, tensile shear tests carried out to evaluate strength joint. results show that ...

The Unsteady laminar flow of an electrically conducting dusty viscous incompressible fluid near an accelerated flat, nonconducting plate, under the influence of a uniform magnetic field and pulsatile pressure gradient has been studied using differential geometry techniques i.e., in Frenet frame field system. The particular cases as (i) impulsively moving and (ii) uniformly accelerated motion of...

The Casimir force is one of the most accessible experimental consequences of vacuum fluctuations in the macroscopic world. It is the most significant force between neutral, non-magnetic objects at distances on the micrometer scale and below. For many experiments searching for novel short-range forces predicted by unification models, theoretical calculations of the Casimir force are crucial and ...
