High brightness LED working principle and heat generation: High brightness LED is a semiconductor light-emitting device, through the current through the semiconductor material when the electron – hole complex process, the conversion of electrical energy into light energy. However, this conversion process...
“digital natives”—the first generation to grow up with the internet as a part of daily life. The generation spans a wide range: the oldest Gen Zers have jobs and mortgages, while the youngest are still preteens. Globally, Gen Z is growing fast: Gen Zers willmake up a quarter of ...
For heat generation, it is usually better to have a lower value. Though in some instances where the change in resistance can be accurately predicted, a sharp increase in resistance is desirable to deliver more power. To make the system adjust for the changing resistivity, control or feedback ...
Eight-year-old Jon Kent's life has been pretty normal, really -- growing up on his grandparents' farm in Smallville, Kansas, his mom raising him while his dad, whom he's never even met, is off on some long undercover assignment overseas. But things change pretty quickly one afternoon ...
PAM4 doubles the network interface rate by upgrading the internal electrical chip of the optical module. Fortunately, the existing network control chips (for example, X86 chips) and the intra-board or inter-board interfaces (for example, SerDes interfaces) of high-end devices are able to proces...
Learn the basics of hybrid vehicle technology as well as the difference between a parallel, series, and plug-in hybrid.
Every company wants its customer churn rate to be 0%, which is sort of impractical. You can still keep it somewhat closer to 0%, and to do that, you need to know where you currently stand. A popular formula used for calculating churn is:There are many ways to calculate it:...
Mobility.The energy transition requires the decarbonization of transportation, including cars, trucks, aviation, and shipping. There remain fundamental performance gaps between electric vehicles and internal combustion engines in longer-range mobility, including trucking, aviation, and shipping. ...
“For [solar] arrays that are close to the optimum orientation, the annual energy generation is only slightly reduced,” says a spokesperson from the Solar Energy Technologies Office at the Department of Energy. For example, panels that face 10 degrees west of the ideal direction (aka azimuth)...
Tests should evaluate key elements of the plan, including reaction times to power outages and IT failures, the viability of both internal and external communications systems, and alert and activation procedures for key personnel. Testing not only familiarizes people with their responsibilities in the ...
