Are Neural Networks Collision Resistant?

Physical Review X
Collision-resistant hash functions are a fundamental cryptographic primitive that rely on the computational hardness of finding two inputs that produce the same output. Motivated by this problem, we study the complexity of finding collisions in a family of neural networks with oscillating activation functions.

RESEARCH ON THE ANTI-IMPACT CHARACTERISTIC AT DIFFERENT LOCATION BETWEEN THE MOVING SHIP AND MONOPILE OFFSHORE WIND TURBINES

Jixie qiangdu, 2019
With tidal fluctuations, deep ship and deep draft changes, will inevitably lead to ship and offshore wind turbine collision location changes. In order to study the effect of collision location on the impact resistance of offshore wind turbine structure ...

Experimental and numerical studies on the roller–cage collision mechanism in a cylindrical roller bearing

Friction
In rolling bearings, roller–cage collisions are one of the primary causes of cage damage. However, the underlying mechanisms remain unclear, particularly under high radial loads.

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Study on the Influence of the Mechanical Characteristics of the Cutting-Type Anti-Climbing Energy Absorber on the Collision Behavior of the GFRP Head Cover for Subways

Machines
Anti-climbing energy absorbers (AEAs) are often installed at the ends of subway vehicles to prevent climbing in the event of a head-on collision or rear-end collision, thereby improving safety performance.
