In this video, Ash Marlow explains a simple magic trick where a coin appears to vanish and then return. The method uses a small piece of double-sided tape placed on the back of the hand. By tossing ...

There are many approaches to pricing. These include cost-based, going-rate, target profit, cost-plus, and break-even approaches. When you think about it, all of these approaches to pricing a product ...

Abstract: For speed-sensorless induction motor (IM) drives (SSIMD), the adaptive magnetizing current control has already been presented to enhance the speed observability at low synchronous speeds.

Abstract: This paper proposes a 13-bit fully parallel two-step single slope (TS-SS)ADC for high speed CMOS image sensors. The ADC design method is based on the idea of time sharing and time ...

Waveguide-enhanced Raman spectroscopy utilizes electromagnetic enhancements at waveguide surfaces to improve Raman signal intensity. This Primer discusses laser selection, waveguide design, light ...
