A Review of Evaluations of Bicycle Safety Education as a Countermeasure for Child Cyclist Injury
Journal of Road Safety, 2012 Children should be encouraged to cycle for its health and psychological benefits and because of the value of forming healthy habits early in life. Children who cycle are more likely to become adults who cycle, and cycling has clear health benefits, even ...

Enhanced Dynamic Duty Cycle in LoRaWAN Network [PDF]
, 2018 LoRa’s long-range and low-power features have made it an attractive candidate for IoT devices in various fields. In this work, we present an enhanced LoRaWAN protocol. LoRaWAN MAC protocol is characterized by the restrictive use of the channel, limited by the regulatory authorities to a 1% duty cycle per cycle (i.e., 36 s per hour) per node.

International Journal of Distributed Sensor Networks, 2017 In wireless sensor networks, duty cycling has been an imperative choice to reduce idle listening but it introduces sleep delay. To break through the energy-latency tradeoff, we propose a pair of a radio wave sensor called radio frequency wakeup sensor ...

DLL Design with Wide Input Duty Cycle Range and Low Output Clock Duty Cycle Error
MicromachinesThis paper presents the design of a Delay-Locked Loop (DLL) with a simple architecture and a wide input clock duty cycle range. The design is tailored to meet the increasing data rate and stringent clock requirements of modern semiconductor chips, with particular applicability to dynamic random-access memory (DRAM) systems.
