Analog computers are systems that perform computations by manipulating physical quantities such as electrical current, that map math variables, instead of representing information using abstraction ...

Machine learning models called convolutional neural networks (CNNs) power technologies like image recognition and language ...

Combining Cor Van Rij's JFET test socket with two DMMs, a current limiter, switches and a wall wart yield a simple, accurate ...

The authors have performed a potentially valuable new kind of analysis in connectomics, mapping to an interesting developmental problem of synaptic input to sensory neurons. While the analysis itself ...

Working from home by day, gaming and streaming by night? Defeating Wi-Fi dead zones is more important than ever. A mesh network system can help, and these are the best we've tested. I’ve been working ...

The bar model method is a great way to visualise tricky mathematical concepts and solve problems. They are a quick and easy way to represent a situation in a word problem. Bar modelling can be used to ...

The latest, greatest phones can now survive a dip in the pool. But how manufacturers create and define "water resistance" may surprise you. When his parents denied him a Super NES, he got mad. When ...

Are you a low, medium or high user of gas and electricity? Estimated energy use figures How to find your actual energy usage figures How to work out the running cost of appliances The energy price cap ...

Abstract: Compared to electric vehicle battery swapping stations (BSSs) based on dc voltage bus (DVB), the series-connected BSS based on dc current bus (DCB) can achieve independent control of each ...

Abstract: This paper proposes a novel method for calculating winding inductances in electrical machines using mesh-based magnetic equivalent circuit (MEC). In the proposed framework, the inductances ...
