Revising hip fracture rehabilitation in the elderly
(2019)
A 30-year study in Greece showed that the incidence of hip fractures due to osteoporosis has tripled over this period. Hip fractures are usually due to a traumatic event, and require surgical intervention to fix the fracture ...
Bone mineral density in vocational and professional ballet dancers
(2017)
Summary: According to existing literature, bone health in ballet dancers is controversial. We have verified that, compared to controls, young female and male vocational ballet dancers have lower bone mineral density (BMD) ...
Development of wood composites from recycled fibres bonded with magnesium lignosulfonate
(2020)
The potential of producing ecofriendly composites from industrial waste fibres, bonded with magnesium lignosulfonate, a lignin-based formaldehyde-free adhesive, was investigated in this work. Composites were produced in ...
Grain and grain boundary transport in BaCe0.5Zr0.3Ln0.2O3−Δ (Ln – Y or lanthanide) electrolytes attractive for protonic ceramic fuel cells application
(2017)
Protonic ceramic fuel cells (PCFCs) belong to very attractive energy conversion systems, which are able to operate effectively at low- and intermediate temperature ranges. The improvement of their electrochemical characteristics ...
vhMentor: An Ontology Supported Mobile Agent System for Pervasive Health Care Monitoring
(2017)
Healthcare provision is a set of activities that demands the collaboration of several stakeholders (e.g. physicians, nurses, managers, patients etc.) who hold distinct expertise and responsibilities. In addition, medical ...
ASML: Algorithm-Agnostic Architecture for Scalable Machine Learning
(2021)
Machine Learning (ML) applications are growing in an unprecedented scale. The development of easy-to-use machine-learning application frameworks has enabled the development of advanced artificial intelligence (AI) applications ...
Multi-scale modeling of the dynamics of a fibrous reactor: Use of an analytical solution at the micro-scale to avoid the spatial discretization of the intra-fiber space
(2020)
Direct modeling of time-dependent transport and reactions in realistic heterogeneous systems, in a manner that considers the evolution of the quantities of interest in both, the macro-scale (suspending fluid) and the ...
Sharp bounds on the spectral radius of nonnegative matrices and comparison to the frobenius’ bounds
(2020)
In this paper, a new upper bound and a new lower bound for the spectral radius of a nοnnegative matrix are proved by using similarity transformations. These bounds depend only on the elements of the nonnegative matrix and ...
A Low-cost & Realtime Motion Capture System
(2022)
Traditional marker-based motion capture requires excessive and specialized equipment, hindering accessibility and wider adoption. In this work, we demonstrate such a system but rely on a very sparse set of low-cost ...
Frost and remote sensing: An overview of capabilities
(2017)
In this chapter, the capabilities of Earth observation (EO) for use in frost quantification and assessment are discussed. First, a description of frost concepts and classification is presented. This is followed by a ...
