Effects of fin stabilizer configurations on semi swath resistance [PDF]

, 2017
The installation of the fin stabilizers on the Semi Small Waterplane Area Twin Hulls (Semi SWATH) vessel reduces the disadvantages of its low restoring force.

Autonomous and Continuous Atmospheric Water Harvesting Using Modified Wood

Advanced Science, EarlyView.
A rigid, hydroxyl‐rich wood skeleton with graded channels is used as a multifunctional host to co‐incorporate a PNipam/PAA network and LiCl, creating a high‐performance sorbent for atmospheric water harvesting. The composite achieves rapid sorption, efficient low‐temperature desorption, and stable cycling, enabling a solar‐powered device with a high ...

Stability Criterion for a Finned Spinning Projectile

Defence Science Journal, 2000
The state-of-the-art in gun projectile technology has been used for the aerodynamic stabilisation.This approach is acceptable for guided and controlled rockets but the free-flight rockets suffer fromunacceptable dispersion. Sabot projectiles with both spin and fms developed during the last decadeneed careful analysis.

Assessing Linear Control Strategies for Zero-Speed Fin Roll Damping [PDF]

Roll stabilization is a critical aspect of ship motion control, particularly for vessels operating in low-speed or zero-speed conditions, where traditional hydrodynamic fins lose their effectiveness.

Tailoring Multifunctional Carbon Dots via Precursor Stoichiometry: Switching Between Solid‐State Fluorescence and Broadband Absorption Through Aggregation Control

Advanced Science, EarlyView.
Precursor stoichiometry programs the surface chemistry of carbon dots, directing their self‐assembly into distinct aggregation modes. Aldehyde‐enriched surfaces form ordered, hydrogen‐bonded assemblies that enable bright red solid‐state fluorescence, whereas amine‐rich surfaces promote compact π–π stacked aggregates with broadband visible‐light ...

Hydrodynamic Fin Function of Brief Squid \u3ci\u3eLolliguncula brevis\u3c/i\u3e [PDF]

, 2007
Although the pulsed jet is often the foundation of a squid\u27s locomotive system, the lateral fins also play an important role in swimming, potentially providing thrust, lift, and dynamic stability.

Evolution of Physical Intelligence Across Scales

Advanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Parametric Analysis of Spiking Neurons in 16 nm Fin Field‐Effect Transistor Technology

Advanced Intelligent Discovery, EarlyView.
Energy efficient computing has driven a shift toward brain‐inspired neuromorphic hardware. This study explores the design of three distinct silicon neuron topologies implemented in 16 nm fin field‐Effect transistor technology. While the Axon‐Hillock design achieves gigahertz throughput, its functional fragility persists. The Morris–Lecar model captures

Fin stabilized projectiles point mass model

Journal of Physics: Conference Series, 2020
Abstract To calculate flight of unguided projectiles several types of the flight models are used. The application mostly depends on demand of the model accuracy, complexity and computational cost. As a good compromise of these three features for flight calculation of spin stabilized projectiles Modified Point Mass Trajectory Model was ...
