Determination of the parameters of the dynamic braking roller of the gravity pallet rack [PDF]

Научно-технический вестник Брянского государственного университета
The use of a block storage system and optimization of picking routes in warehouses reduces the costs of basic logistics operations. Equipping warehouses with racks with a gravity roller conveyor ensures a more compact arrangement of products in ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Comparative processing studies of the Arkachan deposit gold-bearing ores using dry separation and classical wet gravity separation methods

Горные науки и технологии
The use of dry methods of processing and beneficiation of mineral raw materials is one of the promising areas, as this approach to concentrate production is less energy-consuming, less labor-intensive, and economically beneficial.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Regolith behavior under asteroid-level gravity conditions: low-velocity impact experiments

Progress in Earth and Planetary Science, 2018
The dusty regolith covering the surfaces of asteroids and planetary satellites differs in size, shape, and composition from terrestrial soil particles and is subject to environmental conditions very different from those found on Earth.

Experimental study on gravity currents flowing on heated walls

Experiments in Fluids
Abstract We present an experimental study on steady gravity currents advancing along a heated wall. The study aims to assess how the structure and dynamics of a wall-heated current are modified with respect to the adiabatic-wall case.

Weak mixing angle under U(1, 3) colored gravity

Journal of High Energy Physics
Colored gravity, based on U(1, 3) symmetry, emerges naturally in the complexification of Lorentzian manifolds and integrates U(1) electromagnetism as a subcase.

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...
