Background and Objectives: Today, the main basis of diagnosis and treatment in medicine is the obtained evidence from the research.One of the movements that have attempted to establish this basis is evidence-based medicine (EBM).The present review dealt with the philosophical assessment of this subject.Methods: In this study, EBM-related data from
This study presents a compact high-gain antenna, designed to be mounted on unmanned aerial vehicles, for millimeter-wave band applications.This antenna combines a slotted waveguide array (SWA) with a cubic post radiator (CPR) for performance enhancement.By utilizing the CPR structure, the radiation of the SWA antenna can be effectively focused in a
In energy harvesting Internet of Things (IoT) systems, the age of information (AoI) should be maintained at a low level to guarantee the accuracy and reliability of derived decisions.In this paper, we design an information freshness-guaranteed and energy-efficient data generation control system (IFE-DGCS) where an IoT gateway with a directional ant
Background: The indigenous KwaZulu-Natal Sandstone Sourveld (KZN SS) grassland is highly endemic and species-rich, yet critically endangered and poorly conserved.Ecological threats to this grassland ecosystem Volleyball - Balls - Competition are exacerbated by encroachment of woody plants, with severe negative environmental and economic consequence
Labyrinth seals are a state-of-the-art sealing technology to prevent and control leakage flows at rotor–stator interfaces in turbomachinery.Higher pressure ratios and the economical use of cooling air require small clearances, which lead to potential rubbing events.The use of honeycomb liners allows for minimal leakage by tolerating rub event
