Statistical model for collisions and recollisions of inertial particles in mixing flows [PDF]

open access: green, 2016
Finding a quantitative description of the rate of collisions between small particles suspended in mixing flows is a long-standing problem. Here we investigate the validity of a parameterisation of the collision rate for identical particles subject to ...

Collision Helps - Algebraic Collision Recovery for Wireless Erasure Networks [PDF]

open access: yes, 2010
Current medium access control mechanisms are based on collision avoidance and collided packets are discarded. The recent work on ZigZag decoding departs from this approach by recovering the original packets from multiple collisions.

Identification of Key Nodes in Aircraft State Network Based on Complex Network Theory

open access: yesIEEE Access, 2019
With the development of aviation, the air traffic density in the terminal area is high and the traffic situation is relatively complex, which brings challenges to the flight deployment.

A Class of Collisions of Plane Impulsive Light--Like Signals in General Relativity [PDF]

open access: yes, 2002
We present a systematic study of collisions of homogeneous, plane--fronted, impulsive light--like signals which do not interact after head--on collision. For the head--on collision of two such signals, six real parameters are involved, three from each of

Critical Altitudinal Shift From Detrital to Pedogenic Origin of the Magnetic Properties of Surface Soils in the Western Pamir Plateau, Tajikistan

open access: yesGeochemistry, Geophysics, Geosystems, 2020
Sedimentary archives of the westerlies‐influenced Pamir Plateau in Tajikistan, a climatically sensitive region in arid central Asia, provide information on past climatic changes and the tectonic evolution of the northern Tibetan Plateau.

Time-Coordinated Control for Unmanned Aerial Vehicle Swarm Cooperative Attack on Ground-Moving Target

open access: yesIEEE Access, 2019
In this paper, cooperative attack control law analysis and design problems for unmanned aerial vehicle (UAV) swarm attack on ground-moving target with time-coordinated strategies are investigated.

Binomial collisions and near collisions

open access: yesIntegers : Electronic Journal of Combinatorial Number Theory, 2017
We describe efficient algorithms to search for cases in which binomial coefficients are equal or almost equal, give a conjecturally complete list of all cases where two binomial coefficients differ by 1, and give some identities for binomial coefficients that seem to be new.

Colliding Impulsive Gravitational Waves and a Cosmological Constant [PDF]

open access: yes, 2015
We present a space--time model of the collision of two homogeneous, plane impulsive gravitational waves (each having a delta function profile) propagating in a vacuum before collision and for which the post collision space--time has constant curvature ...

A Late Miocene Terrestrial Temperature History for the Northeastern Tibetan Plateau's Period of Tectonic Expansion

open access: yesGeophysical Research Letters, 2019
During the Late Miocene, the climate patterns and ecosystems of continental land masses experienced crucial transitions, but whether the principal driver was regional tectonic forcing or a decline in CO2 concentrations remains debated.

Redundant neural vision systems: competing for collision recognition roles [PDF]

open access: yes, 2013
Ability to detect collisions is vital for future robots that interact with humans in complex visual environments. Lobula giant movement detectors (LGMD) and directional selective neurons (DSNs) are two types of identified neurons found in the visual ...
