Probabilistic generation of wreath products on non-abelian finite simple groups [PDF]

open access: yes, 2004
We show that the probability of generating an iterated standard wreath product of non-abelian finite simple groups is positive and tends to 1 as the order of the first simple group tends to infinity.

The behaviour of laterally loaded two-pile groups [PDF]

open access: yes, 1992
The response of piles and two-pile groups to lateral loading has been studied by field tests and computationally. Due to the lack of field test data and because of uncertainty concerning the pile/soil system it has been suggested that further ...

Finite simple groups of small essential dimension [PDF]

open access: yes, 2014
International audienceWe show that the only finite simple groups of essential dimension 3 (over C) are A_6 and possibly PSL(2,11). This is an easy consequence of the classification by Prokhorov of rationally connected threefolds with an action of a ...

Chermak-Delgado Simple Groups [PDF]

open access: yes, 2015
This paper provides the first steps in classifying the finite solvable groups having Property A, which is a property involving abelian normal subgroups. We see that this classification is reduced to classifying the solvable Chermak-Delgado simple groups,

The classification of local m-GCI-group on finite nonabelian simple groups

open access: yes, 2019
Li and Praeger classified finite nonabelian simple groups, it has only one or two fusion classes of any certain value. As a by-product, they classified m-CI-groups, which is critical in the research of Cayley graphs. In the paper, we will consider generalized Cayley graphs. This concept is proposed by Marusic et al.

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

open access: yesAdvanced 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 ...
