This paper presents investigations of dynamic behaviour of a nonlinear Gantry Crane System (GCS). The dynamic model is derived using Lagrange equation. Various system parameters of the system are tested to observe the actual behaviour of the dynamic model system. System responses including trolley displacement and payload oscillation are analyzed. Simulation is conducted within Matlab environme...

We determine the maximum area of a rectangular food trolley that can be pushed around a corner. We also discuss various pushing strategies.

HyperMask is a system which projects an animated face onto a physical mask, worn by an actor. As the mask moves within a prescribed area, its position and orientation are detected by a camera, and the projected image changes with respect to the viewpoint of the audience. The lips of the projected face are automatically synthesized in real time with the voice of the actor, who also controls the ...

Junior doctors, nursing staff, and phlebotomists spend a large proportion of their time taking blood samples and siting (venous) cannulae. Approximately 350 blood samples are taken daily across 25 wards at the Royal United Hospital Bath NHS Trust. There is no standard storage solution for venepuncture or cannulation equipment. On-call junior doctors cover most of the hospital's wards. Time is w...

RFID (radiofrequency identification) technology offers the ability to provide many new services and conveniences in the retail environment. An innovative product with societal acceptance is the one that aids the comfort, convenience and efficiency in everyday life. Purchasing and shopping at big malls is becoming daily activity in various cities. We can see big rush at these malls on holidays a...

This study proposes a feedforward (FF) control input generation method that can realize automatic anti-sway transport of suspended load for crane system with restrictions the trolley only accelerate or decelerate at constant rate; switching frequency acceleration cannot be too high. First, time-continuous FF is derived by using time-polynomial (FFT) method, which basis our method. Next, FFT app...

OBJECTIVE Babies receive oxygen through their umbilical cord while in the uterus and for a few minutes after birth. Currently, if the baby is not breathing well at birth, the cord is cut so as to transfer the newborn to a resuscitation unit. We sought to develop a mobile resuscitation trolley on which newly born babies can be resuscitated while still receiving oxygenated blood and the 'placenta...
