Impact-parameter dependence of K-shell ionisation in slow collisioons of near-symmetric relitivistic atoms [PDF]

open access: yes, 1982
. The total K vacancy production probability of both collision partners in a heavy-ion-atom collision is calculated, assuming that two processes contribute, a single-collision process where 2po and 2pa vacancies are created by direct ionisation of the ...

Deep Neural Network Compression for Aircraft Collision Avoidance Systems [PDF]

open access: yesJournal of Guidance Control and Dynamics, 2018
One approach to designing decision making logic for an aircraft collision avoidance system frames the problem as a Markov decision process and optimizes the system using dynamic programming.

Flexural Behavior of Bidirectionally Graded Lattice

open access: yesAdvanced Engineering Materials, EarlyView., 2023
An experimental study of the bending behavior of bidirectional body‐centered cubic lattice beams is conducted in comparison to uniform and unidirectional counterparts of electron beam melted SS 316 L. Experimental results are used to develop and validate a finite element model which is subsequently used to conduct parametric studies to assess the ...

Unresectable Intermediate-Size (3–5 cm) Colorectal Liver Metastases: Stereotactic Ablative Body Radiotherapy Versus Microwave Ablation (COLLISION-XL): Protocol of a Phase II/III Multicentre Randomized Controlled Trial [PDF]

open access: yes, 2023
Background: Although microwave ablation (MWA) has a low complication rate and good efficacy for small-size (≤ 3 cm) colorectal liver metastases (CRLM), local control decreases with increasing size.

Probabilistic seismic hazard assessment of Nepal using multiple seismic source models

open access: yesEarth and Planetary Physics, 2018
The potential for devastating earthquakes in the Himalayan orogeny has long been recognized. The 2015 MW7.8 Gorkha, Nepal earthquake has heightened the likelihood that major earthquakes will occur along this orogenic belt in the future.

Is the super-Penrose process possible near black holes? [PDF]

open access: yes, 2016
We consider collisions of particles near generic axially symmetric extremal black holes. We examine possibility of indefinitely large extraction of energy (the so-called super-Penrose process) in the limit when the point of collision approaches the ...

Simulation‐based forecasting effects of an accidental explosion on the road. Part II: Case study [PDF]

open access: yesTransport, 2006
The paper contains a case study covering forecasting mechanical effects of an explosion which can be generated during a road accident. It illustrates a practical application of the simulation‐based procedure developed for such forecasting in the first ...

An algorithm for planning collision-free paths among polyhedral obstacles

open access: yesCACM, 1979
This paper describes a collision avoidance algorithm for planning a safe path for a polyhedral object moving among known polyhedral objects. The algorithm transforms the obstacles so that they represent the locus of forbidden positions for an arbitrary ...
