We introduce a design with dual resonant structure which can harvest energy from random vibration sources at low frequency range.The Journal dual resonant structure consists of two spring-mass subsystems with different frequency responses, which exhibit strong coupling and broad bandwidth when the two masses collide with each other.Experiments with
Many people, particularly in Africa, suffer various conditions from eating bitter cassava which contains poisonous cyanogens.As well as poisoning, which sometimes causes death, these conditions include konzo, an irreversible paralysis of the legs, which affects mainly children and young women, impaired neurocognition in children, tropical ataxic ne

The increase in world population has led to a significant increase in the numbers of cars and used tyres.These tyres must be disposed of on an ongoing basis as a result of their consumption or deterioration.This can result in negative effects on the environment that must be preserved, especially from those materials, i.e., these waste materials are
