The anode current is a very important parameter in the aluminum electrolysis production. However at present, manual measurement is still being used in the aluminum industrial. There are some shortcomings, such as low measurement precision, data lag, etc. This approach can't meet the requirements of the modern management and production for aluminum electrolysis. Based on the principle of anode rod...
Topside-ionospheric parameters recorded by the Instruments: Sonde de Langmuir (ISL), Analyseur de Plasma (IAP) and Capteur Electrique (ICE) onboard the DEMETER spacecraft during 85 days spanning the M8.0 Wenchuan Earthquake on 12 May, 2008 were investigated statistically. The influence of geomagnetic activity was removed from the records through confining the data investigated to periods characterized...
The degradation of high power GaN-based blue light-emitting diodes (LEDs) was investigated by considering the electrical, optical and electroluminescence spectrum aging characteristics. The LED samples are stressed at the condition of 85°C and 85% RH using an injection current of 1000 mA. Optical output power decreases to 80% of initial value after 1000 hours of temperature/humidity accelerated tests...
