Regarding spatial location positioning, indoor location positioning theories based Lift Chairs on wireless communication techniques such as Wi-Fi, beacon, UWB and Bluetooth has widely been developing across the world.These techniques are mainly focusing on spatial location detection of customers using fixed wireless APs and unique Tags in the indoo
A range of soft robotic systems have recently been developed that use soft, flexible materials and respond to environmental stimulus.The greatest challenge in their design is the integration of the actuator, energy sources, and body of robots while achieving fast locomotion and well-defined programmable trajectories.This work presents such a design
Abstract To bolster long-range maritime communication, unmanned aerial vehicle (UAV)-aid communications have garnered increased attention as traditional maritime communication solutions face challenges from geographical and meteorological factors.This work first introduces a UAV-aided wireless communication system based on elevated ducts, offering
This paper presents the dynamic analytical solution of a piezoelectric stack utilized in an actuator and a generator based on the linear piezo-elasticity theory.The solutions for two different kinds of piezoelectric Under Armour stacks under external load were obtained using the displacement method.The effects of load frequency and load amplitude o
Abstract Phenotype alterations can occur naturally during the life span of the domestic fowl.These alterations increase the risk to become a target of aggression and may cause a severe impact on the welfare of affected birds.We analysed the behavioural consequences of sequential phenotype alterations and their long-term effects within stable social
