Link-Correlation-Aware Opportunistic Routing in Low-Duty-Cycle Wireless Networks

open access: yesSensors, 2021
In low-duty-cycle wireless networks with unreliable and correlated links, Opportunistic Routing (OR) is extremely costly because of the unaligned working schedules of nodes within a common candidate forwarder set.

A 50–1600 MHz Wide–Range Digital Duty–Cycle Corrector With Counter–Based Half–Cycle Delay Line

open access: yesIEEE Access, 2023
Duty-cycle distortion may occur due to variations in the process, voltage, and temperature, or if the clock signal passes through clock buffers. To compensate duty-cycle distortion, a digital duty-cycle corrector (DCC) with counter-based half-cycle delay

A Defense of Free-Roaming Cats from a Hedonist Account of Feline Well-being [PDF]

open access: yes, 2019
There is a widespread belief that for their own safety and for the protection of wildlife, cats should be permanently kept indoors. Against this view, I argue that cat guardians have a duty to provide their feline companions with outdoor access.

Reinforcement Learning Based Adaptive Duty Cycling in LR-WPANs

open access: yesIEEE Access, 2020
For conserving energy, duty cycle is defined by setting up the active and sleep periods of network nodes. In beacon enabled networks, to provide support for duty cycle, the IEEE 802.15.4 standard uses optional super-frame structure.
