A new lease on life for old laptops

Credit: Pixabay/CC0 Public Domain Researchers in India have developed a tool that can estimate the remaining useful life of an otherwise obsolete laptop computer based on quality grading of two of its main components—hard drive and rechargeable lithium-ion battery. The work, published in the International Journal of Process Management and Benchmarking, focused on developing a […]

Controlling chaos using edge computing hardware: Digital twin models promise advances in computing

NG-RC based nonlinear controller realized on edge computing hardware. (top) Learning phase. (top) Learning phase. A field programmable gate array (FPGA) applies perturbations (red) to a chaotic circuit and the perturbed dynamics of the circuit (blue) are measured by a sensor (analog-to-digital converters). The temporal evolution of the perturbations and responses are transferred to a […]

A new, low-cost, high-efficiency photonic integrated circuit

Lithium tantalate photonic integrated circuits. Credit: Tobias Kippenberg (EPFL) The rapid advancement in photonic integrated circuits (PICs), which combine multiple optical devices and functionalities on a single chip, has revolutionized optical communications and computing systems. For decades, silicon-based PICs have dominated the field due to their cost-effectiveness and through their integration with existing semiconductor manufacturing […]
