This invention relates to a system that continuously measures and monitors the dynamic behavior of turbomachine blades in order to provide early warning of incipient blade failure. This would enable management to take corrective action in order to prevent failure and downtime. The system be used in...

 

This technology uses Unmanned Aerial Vehicles (UAVs) fitted with a camera to calibrate heliostats in large Concentrating Solar Power (CSP) or Concentrating Solar Thermal (CST) tower systems. The UAV does not have a single fixed position and provides several advantages over traditional methods...

Irrigation is an essential part of commercial agriculture. The water and energy used in typical large-scale irrigation systems can be substantial. As water becomes a scarcer resource its responsible use and conservation become imperative. The same is true of energy especially in territories where...

Background:

Cellulose and Chitin are the two most abundant natural biopolymers in the world. Both are characterised as water‑insoluble in their natural states. 

Chitin is a white, hard, inelastic polysaccharide found primarily in the exoskeleton and internal structures of invertebrates such as...

The technology is a membrane for treating acid mine drainage that is reproducible and can handle large discharges of acid mine drainage. It is suitable for implementation in a filtration cartridge setup that allows for the reclamation of metals which can then be recycled and used for other...

Background:

Obstructive Sleep Apnoea (OSA) is a debilitating condition with significant morbidity and mortality characterized by blockage of the upper airway during sleep as a result of collapse of the soft tissues in the throat. OSA affects approximately 6-8.5% of the adult population in western...

Conventional narrow-bandwidth low-noise amplifiers (LNA’s) can achieve noise figures close to the theoretical minimum noise figure of the high electron mobility transistor  (HEMT) devices that are being used (red curve). The wider the bandwidth, however, the more difficult it becomes to achieve a...

The North-West University has developed a universal, remote and digital interpretation system for PCR results that allows for point of care diagnosis. A difficulty in times of pandemic, for example, during the COVID-19 pandemic, is that there are large numbers of people requiring testing to identify...

Surfactants are amphipathic molecules with both hydrophilic and hydrophobic moieties that partition preferentially at the interface between fluid phases such as oil/water or air/water interfaces. Such characteristics confer excellent detergency, emulsifying, foaming, and dispersing traits, which...

Background

Leak detection and management is an important topic in the management of water distribution systems. Various instruments and measurement techniques have been developed to identify the occurrences and locations of new leaks in large distribution systems and networks.
