Abstract

This paper presents our preliminary results with ABEONA, an edge-to-cloud architecture that allows migrating tasks from low-energy, resource-constrained devices on the edge up to the cloud. Our preliminary results on artificial and real world datasets show that it is possible to execute workloads in a more efficient manner energy-wise by scaling horizontally at the edge, without negatively affecting the execution runtime., Comment: European Commission Project: LEGaTO - Low Energy Toolset for Heterogeneous Computing (EC-H2020-780681)

2. Analysis of longitudinal and transversal dynamic behavior of multifilament bi-helical auxetic yarns

Abstract

Bi-helical yarns when made by single yarns with different diameters, helix angles and tensile strengths, present a dynamic behaviour that results in a significant difference in the relationship between the transversal and longitudinal variation, that is, in the Poisson´s ratio. The longitudinal and transversal measurement of a bi-helical yarn in a dynamic test is a complex process, especially when dealing with multifilament yarns. For this reason, a methodology was specially developed using image analysis. To demonstrate the dynamic behaviour of the bi-helical yarns under tensile loads, the results obtained for four different samples using polyamide and polyester multifilament yarns are presented and analysed.
