Present cable trolley brakes used in material transfer or overhead trolley transport systems uses twin shoe caliper brakes operated by solenoid. These brakes are not fail safe, means that slip occurs between cable and brake caliper. Sometimes overloading leads to wear of brake shoe material. The failure of brake system may increase the chances to loss of life of occupant. These conventional cal...

An elderly man was brought to our emergency department with an occipital head injury sustained after a syncopal episode. The ambulance crew packaged him onto an orthopaedic scoop stretcher, with a semi-rigid cervical collar, head blocks and tape. He was alert and orientated. After transferring him onto an emergency department trolley, the sheet on the ambulance trolley was noted to be blood sta...

Many moral psychologists have proposed that the difference between people’s moral judgments about the Trolley and Footbridge dilemmas can be explained by their differing emotional responses to the dilemmas. In two experiments, we tested this explanation by presenting the dilemmas and measuring participants’ reactions using a self-report emotion measure (PANAS-X). As might be expected, participa...

We consider the optimal control of a crane-trolley-load model, where the crane beam is subject to the PDE of static linear elasticity and the motion of the load is described by the dynamics of a pendulum that is fixed to a trolley which moves along the crane beam. The resulting problem serves as a prototype for optimal control of fully coupled partial and ordinary differential equations. This t...
