Investigation on characteristic of LED power density via tapered fiber

Materials Research Express, 2022
In this paper, a tapered fiber for improving the power density of the Light Emitting Diode (LED) was designed. Numerical simulation showed that the tapered fiber makes the LED diverging light sources converge on the microscopic area, which makes the LED ...

Adaptive Fuzzy Control for Power-Frequency Characteristic Regulation in High-RES Power Systems

Energies, 2017
Future power systems control will require large-scale activation of reserves at distribution level. Despite their high potential, distributed energy resources (DER) used for frequency control pose challenges due to unpredictability, grid bottlenecks, etc.

Data Power and Counter-power with Chinese Characteristics

, 2022
AbstractHow to make sense of China as a global data superpower? This chapter attempts to offer new insights that are historicised and holistic, considering China’s internal conflicts and its relations with the external world. It starts by outlining and debunking two myths about China, fetishising it as either dystopia or utopia.

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
