Gaps of size 2, 4, and (conditionally) 6 between successive odd composite numbers occur infinitely often [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
The infinite sequence of gaps (first differences) between successive odd composite numbers contains only the numbers 2, 4, and 6. We prove that, for any natural number k, the sequence of gaps contains infinitely many k-tuplets of consecutive gaps all ...

Research on the Shear Behaviour of Composite Shear Connectors

open access: yesBuildings, 2022
In order to make full use of the advantages of welded stud and perfobond rib shear connectors, a new type of composite shear connector is proposed. Studs are welded to the perforated steel plate of the PBL connectors.

Experimental Investigation of Geosynthetic-Reinforced Pile-Supported Composite Foundations under Cyclic Loading

open access: yesAdvances in Civil Engineering, 2020
A series of model tests were conducted in this study to investigate the deformation characteristics of geosynthetic-reinforced pile-supported (GRPS) composite foundations under cyclic loading. The effects of the applied load, the number of geogrid layers,

Fast Multi-ANN Composite Models for Repeater Optimization in Presence of Parametric Uncertainty for on-Chip Hybrid Copper-Graphene Interconnects

open access: yesIEEE Access, 2023
In this paper, composite models are developed to predict the statistics of the optimal number and size of repeaters required to minimize the power delay product (PDP) of on-chip hybrid copper-graphene interconnects when subject to parametric uncertainty.
