Metasurface Enhanced Photothermal Cement Foam for Robust and High‐Throughput Seawater Desalination

Carbon Energy, EarlyView.
Schematic of 3D metasurface‐enhanced cement foam for robust and high‐throughput seawater desalination. This study presents a cement‐based solar evaporator (CSE) fabricated in one step via viscoelastic lithography with simple negative pressure. In addition to boosting solar‐to‐vapor conversion efficiency via excellent light‐harvesting capacity, the ...

A neural network growing algorithm based on Brownian movement and gravity constraint

Advances in Mechanical Engineering, 2018
A growing algorithm of neural network based on axon growth is developed in this article. At the beginning, the Newtonian gravitation and the Brownian motion are employed to establish an axon growth model, and the constraint function of the neural axon ...

Comparison of modelling approaches for liquid fluidized beds

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study presents a comparison of three promising numerical models for the detailed simulation of liquid–solid fluidized bed. These models differ in their treatment of the solid phase, ranging from treating each particle individually to treating the collection of particles as a continuum.

Gravitational effects on light rays and binary pulsar energy loss in a scalar theory of gravity

, 2003
A scalar bimetric theory of gravity with a preferred reference frame is summarized. Dynamics is governed by an extension of Newton's second law. In the static case, geodesic motion is recovered together with Newton's attraction field.

Coupled Fluid–Structure–Acoustic Analysis of Flow‐Induced Noise Control Using an Elastic Baffle in a Micro Channel

Energy Science &Engineering, EarlyView.
This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

Improbability of collisions in Newtonian gravitational systems [PDF]

Transactions of the American Mathematical Society, 1971
It is shown that the set of initial conditions leading to collision in the inverse square force law has measure zero. For the inverse q q force law the behavior of binary collisions for 1 > q > 3 1 > q > 3 and the behavior of any collision for q =

Newtonian Gravitational Radiation and Waves

Journal of Applied Mathematics and Physics, 2020
In this paper, we review historical Maxwell's equation for gravity and recent studies on the lack of curvature of linear dipole gravitational waves. The extended Newton's gravity necessarily has the continuity equation for the conservation of mass, and with the Gauss' equation associated to gravitational time depending field R, bring about a new field

Comparative Assessment and Benchmarking of Metaheuristic Algorithms for Dynamic Photovoltaic Array Reconfiguration Under Diverse Shading Environments

Energy Science &Engineering, EarlyView.
ABSTRACT The solar photovoltaic (PV) installations, which are essential for renewable energy systems, are vulnerable to partial shading, resulting in considerable power losses and operational inefficiencies. The dynamic reconfiguration of PV arrays has become an effective strategy to mitigate these effects by adaptively modifying the array topology to ...
