making the water cycle more unpredictable. For billions of people, meltwater flows are changing, causing floods, droughts, landslides and sea level rise. Countless communities and ecosystems are ...

Conventional MPPT methods require one voltage and one current sensor ... As the use of encoders, is not preferred for submersible water pumping, this paper uses a sensorless speed and position ...

Abstract: Integrated gate-commutated thyristors (IGCTs) are widely used in power electronics systems such as power converter and solid-state circuit breaker (SSCB ... IGCTs will not exceed 100 °C by ...

Estimation Methods: The methods documented to be in use in estimating water budget components Parameters: The inputs to estimation methods, generally represented by single variables in an estimating ...

Here, we study scaling patterns of urban energy, water, and waste flows as well as other relevant measures in Chinese cities. We divide cities into different groups using an algorithm that ...

Herein, for the first time, the interface modified attapulgite (ATP) at the atomic-molecular level was employed as a photocatalyst for hydrogen production from water under visible light illumination.
