An interesting analog design problem is the precision current source. Many good designs are available, but most are the three-wire types that can be used as a positive (see Figure 1) or a negative ...

Scientists fear warming is driving a collapse in the ocean currents that shape climate far and wide. The ice-choked waters ...

The author tested the best portable tire inflators against his flat truck tire. Here's how each unit performed under ...

Abstract: The number of devices either providing or demanding direct current is growing more and more. This led to the renascence of DC grids and revealed a need for research. One critical component ...

Abstract: We present a design and details of construction of two calorimetric systems that allow us to measure the total loss in high temperature superconducting coils or linear samples carrying ...
