Simple, efficient, and generalized ECG signal quality assessment method for telemedicine applications

open access: yesInformatics in Medicine Unlocked, 2023
Electrocardiogram (ECG) signals recorded by paramedics in an unsupervised environment are prone to errors and noise due to factors such as electrode misplacements and daily activities during prolonged monitoring.

Software Defect Prediction Using Dagging Meta-Learner-Based Classifiers

open access: yesMathematics, 2023
To guarantee that software does not fail, software quality assurance (SQA) teams play a critical part in the software development procedure. As a result, prioritizing SQA activities is a crucial stage in SQA.

Demonstration of a scaling advantage for a quantum annealer over simulated annealing

open access: yes, 2018
The observation of an unequivocal quantum speedup remains an elusive objective for quantum computing. The D-Wave quantum annealing processors have been at the forefront of experimental attempts to address this goal, given their relatively large numbers ...

Planar trees, slalom curves and hyperbolic knots [PDF]

open access: yes, 1998
We deduce from a rooted tree in the disk a slalom divide and a slalom knot. A slalom knot is either the local link of a simple plane curve singularity of type A_2n, E_6, E_8 or a fibered hyperbolic knot with very special monodromy.Comment: 10 pages and ...

Towards Ontology-based SQA Recommender for Agile Software Development [PDF]

open access: yesJournal of Information Technology & Software Engineering, 2015
Agility is heavily dependent on tacit knowledge, skilled and motivated employees, and frequent communications. Although, the Agile Manifesto claims fast and light software development process while maintaining high quality, it is however not very clear how current agile practices and methods attain quality under time pressure and unstable requirements.

Active Electrically Small Antenna Based on Superconducting Quantum Array

open access: yes, 2012
We introduce Superconductive Quantum Arrays (SQAs) and propose to use these structures as active Electrically Small Antennas (ESA). Several prototypes of the active ESA were fabricated using Nb process with critical current density 4.5 kA/cm2 and ...

Quality-Aware PPG-Based Blood Pressure Classification for Energy-Efficient Trustworthy BP Monitoring Devices With Reduced False Alarms

open access: yesIEEE Access
Early detection of hypertension (HT) is crucial for significantly reducing the risk of serious health complications, which demands continuous or long-term blood pressure (BP) monitoring to ensure the timely management of hypertension. This paper proposes

Spin relaxation and spin Hall transport in 5d transition-metal ultrathin films [PDF]

open access: yes, 2014
The spin relaxation induced by the Elliott-Yafet mechanism and the extrinsic spin Hall conductivity due to the skew-scattering are investigated in 5d transition-metal ultrathin films with self-adatom impurities as scatterers.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.
