An evaluation of the pressure-leakage response of selected water distribution networks in South Africa
Pressure is one of the major factors influencing leakage in water distribution systems. For this reason, pressure management has become standard practice in reducing leakage in water distribution networks around the world. A range of N1 values have been published following studies of the impact of …

An active seating system for prevention of pressure sores
A pressure management and relief system has been developed for use by wheelchairbound individuals who are at risk of developing pressure sores. This system can be used in passive or active form, depending on an individual's requirement for pressure management and relief. The active seat uses vacuum …

Steps Towards a Closed-Loop System for Blood Pressure Control
Management of blood pressure in the operating room is currently done manually by anesthesiologists. Poor blood pressure management has been linked to poor postoperative outcomes. As such, development of a closed-loop system for blood pressure control is warranted, given it produces improved patient …
