Collision resistance of orthogonally stiffened shell structures
Journal of Constructional Steel Research, 1988Abstract Detailed results are given of an experimental investigation into the response of stiffened cylinders to accidental lateral loading. Damage is applied using a knife edge indenter positioned at mid-span. Observations suggest a mechanism by which the light ring frames deform and membrane tension develops in the longitudinal stiffeners.

Collision Strategies for Robot Retreat and Resistance
1991The best collision strategy for a robot is avoidance. If avoidance is not possible or feasible the next best strategy, under certain circumstances, may be 1) partial judicious retreat in order to ameliorate the consequences of collision, or 2) to resist the collision impact in order to maintain stability.

Numerical and experimental investigation on the collision resistance of the X-core structure
Ships and Offshore Structures, 2012This paper analyses the collision resistance of the X-core structure. The analysis includes a detailed investigation of the non-linear plate and laser weld material behaviour using optical, full-field strain measurements. The resulting material relationships are implemented into the finite element model.

Characterizing Collision and Second-Preimage Resistance in Linicrypt
2019Linicrypt (Carmer & Rosulek, Crypto 2016) refers to the class of algorithms that make calls to a random oracle and otherwise manipulate values via fixed linear operations. We give a characterization of collision-resistance and second-preimage resistance for a significant class of Linicrypt programs (specifically, those that achieve domain separation on

Multi-Collision Resistant Hash Functions and Their Applications
2018Collision resistant hash functions are functions that shrink their input, but for which it is computationally infeasible to find a collision, namely two strings that hash to the same value (although collisions are abundant).

Improvement of hash function Edon-R on collision resistance
2016 IEEE International Conference on Information and Automation (ICIA), 2016Collision resistance is one of the most important properties to ensure the safety of a hash function. In this paper, we tweak the quasigroup string transformation R and then give an infinite classes hash functions called “Edon”-R∗ on the base of “Edon”-R, which has a nice property of strongly collision free that can be proved mathematically and ...

Comparative Study on Collision Resistance of Side Structure
Marine Technology and SNAME News, 1997In the second phase of ASIS 's 7-year research project for improved tanker safety against collision and grounding supported by Ministry of Transport, a series of numerical simulations of side damage due to collision was carried out adopting ASIS's methodology based on the customized explicit FEM simulation system in order to demonstrate its potential ...

On Negation Complexity of Injections, Surjections and Collision-Resistance in Cryptography
2016Goldreich and Izsak (Theory of Computing, 2012) initiated the research on understanding the role of negations in circuits implementing cryptographic primitives, notably, considering one-way functions and pseudo-random generators. More recently, Guo, Malkin, Oliveira and Rosen (TCC, 2015) determined tight bounds on the minimum number of negations gates (
