A novel, simple Jerk chaotic circuit with three current feedback operational amplifiers included (CFOA-JCC) is proposed, which has a simpler circuit structure, fewer components, but higher frequency characteristics.The dynamic behaviors of CFOA-JCC Fridge Power Supply PCB are analyzed, including equilibrium, stability, Lyapunov exponent, bifurcatio
PediAppRREST: effectiveness of an interactive cognitive support tablet app in reducing deviations from guidelines in the management of paediatric cardiac arrest: protocol for a simulation-based randomised controlled trial
Introduction Paediatric cardiac arrest (PCA), despite its low incidence, has a high mortality.Its management is complex and deviations from guideline recommendations occur frequently.We developed a new interactive tablet app, named PediAppRREST, to support the management of PCA.The app received a good usability evaluation in a previous pilot trial.
Empowerment in structures. Practical-ethical considerations of the preconditions for technology-assisted dementia care in Germany based on an expert-interview study
BackgroundIntelligent assistive technologies (IAT) have become more common in dementia care.Ethical reflection on technology-assisted dementia care (TADC) has focused so far mainly on individual and interpersonal implications (e.g., self-determination, (in)dependence, safety or privacy issues, caregivers’ support and cost-efficiency).From an empo
Real-world evaluation of the Stemoscope electronic tele-auscultation system
Abstract Background With the spread of COVID-19, telemedicine has played an important role, but tele-auscultation is still unavailable in most countries.This study introduces and tests a tele-auscultation system (Stemoscope) and compares the concordance of the Stemoscope with the traditional stethoscope in the evaluation of heart murmurs.Methods A
