Simulation and Experimental Study of Modern Fiber Metal Laminate Panels Used in Auto Body to Reduce Vehicle Weight [PDF]

International Journal of Advanced Design and Manufacturing Technology, 2011
Automobile body plays crucial role in preventing the collision energy transfer in severe accidents to the passengers. If the collision energy is dissipated or saved in bumper or chassis, the amount of damage to the occupants would be minimized.

Robustness and Collision-Resistance of PhotoDNA

Journal of Cyber Security and Mobility
PhotoDNA is a widely utilized hash designed to counteract Child Sexual Abuse Material (CSAM). However, there has been a scarcity of detailed information regarding its performance. In this paper, we present a comprehensive analysis of its robustness and susceptibility to false positives, along with fundamental insights into its structure.

Defect‐Engineered Microwave‐Responsive Ni@C Composites From Waste PET for Catalytic Plastic Upcycling

Advanced Materials, EarlyView.
A circular upcycling strategy transforms waste poly(ethylene terephthalate) bottles into microwave‐responsive Ni@C catalyst featuring lattice‐distorted nickel cores and defective carbon shells. These strain‐rich heterointerfaces enhance dielectric loss and promote localized microwave hotspots, accelerating peroxymonosulfate activation and polymer‐chain

Collision-resistant hash-shuffles on the reals

Information and Computation
Oneway real functions are effective maps on positive-measure sets of reals that preserve randomness and have no effective probabilistic inversions. We construct a oneway real function which is collision-resistant: the probability of effectively producing distinct reals with the same image is zero, and each real has uncountable inverse image.

High‐Performance Piezoelectric Nanogenerators Based on Wurtzite BeO Nanowire Arrays

Advanced Materials Technologies, EarlyView.
This study demonstrates high‐performance piezoelectric nanogenerators based on 1D BeO nanowire arrays. The BeO nanowires exhibit a high piezoelectric coefficient (∼15.8 pm V−1) and deliver an output voltage of ∼26.1 V and power density of ∼0.32 µW cm−2.

On the power of memory in the design of collision resistant hash functions [PDF]

, 1993
Collision resistant hash functions are an important basic tool for cryptographic applications such as digital signature schemes and integrity protection based on “fingerprinting”. This paper proposes a new efficient class of hash functions based on a block cipher that allows for a tradeoff between security and speed.

Passive Directional Water Transport on Superhydrophobic Gradient Textures Fabricated by Direct Laser Interference Patterning

Advanced Materials Technologies, EarlyView.
Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.
