Viveka: Aerial Navigation Using Passive Computation

Inspired by the energy-efficient navigation of jumping spiders, this paper introduces "Viveka," a biologically inspired aerial navigation system that leverages optical defocus from a large-aperture lens and a monocular event camera to perform passive computation, enabling a quadrotor to navigate complex environments with 85% success and up to 400 times greater computational efficiency than state-of-the-art dense depth estimation methods.

Hydrodynamic impacts of wharf reconstruction aligned with channel expansion under urbanization

This study utilizes a three-dimensional numerical model to demonstrate that while wharf reconstruction in the Shunde Waterway has minimal impact on water levels, the arrangement and geometry of piles significantly alter local velocity fields and create sediment-retention zones, offering critical insights for optimizing wharf design and maintenance.

Comparative analysis on plastic zone in deep soft rock roadway surrounding rock considering rheology or not

This study demonstrates that incorporating rock mass rheology and long-term strength into theoretical and numerical analyses is essential for accurately predicting the deformation and plastic zone of deep soft rock roadways, as neglecting these factors leads to significant overestimation of rock strength and deviation from actual engineering conditions.

Investigating the relationship between kinematic brain injury metrics and brain tissue strain for a football helmet test standard

This study demonstrates that current single-variable kinematic metrics used in football helmet testing poorly predict brain tissue strain, suggesting that incorporating multiple kinematic variables and their directional components would provide a more biologically meaningful assessment of concussive injury risk.

Experimental Study and Wavelet Neural Network Prediction of Unconfined Compressive Strength of Acrylate Copolymer-Emulsion-Cured Saline Soil

This study demonstrates that an independently developed acrylate copolymer emulsion effectively enhances the unconfined compressive strength of saline soil through particle encapsulation and pore filling, while an improved wavelet neural network model successfully overcomes the limitations of traditional approaches to accurately predict this strength based on curing dosage, age, salt content, and moisture content.

Numerical simulation study on ignition process of hydrogen micro-mixed diffusion combustion chamber

This study employs numerical simulations to investigate the ignition process of a hydrogen micro-mixed diffusion combustion chamber, revealing that mixture inhomogeneity, improper ignition timing, and asymmetric injection exacerbate overpressure risks, while reducing injection ports under symmetric conditions offers an optimal ignition scheme to mitigate these safety hazards.
