Sulfide Precipitation in Wastewater at Short Timescales

Short and Long Timescales in Recycles

A new awareness on modelling is growing in the control-oriented community recognising the fact that control is dominantly model based. Since control is about manipulating certain characteristics of the plant, it is no surprise that modelling for control focuses on extracting exactly those characteristics of the plant that are to be controlled. This invariably induces the use of time scale assum...

Prediction at Different Timescales

Timescales of alluvial fan development by precipitation on Mars

[1] Dozens of large, low‐gradient alluvial fans are present within impact crater basins on the cratered highlands of Mars. The timescales and climate conditions that were required to generate such fans are unknown, but testable through our understanding of terrestrial hill slope erosion in the presence of precipitation. Previous estimates of fan formation time vary from years to millions of yea...

Decoding Intention at Sensorimotor Timescales

The ability to decode an individual's intentions in real time has long been a 'holy grail' of research on human volition. For example, a reliable method could be used to improve scientific study of voluntary action by allowing external probe stimuli to be delivered at different moments during development of intention and action. Several Brain Computer Interface applications have used motor imag...

Kinetics of Iron Sulfide and Mixed Iron Sulfide/carbonate Scale Precipitation in Co2/h2s Corrosion

Glass cell experiments were conducted to investigate kinetics of iron sulfide and mixed iron sulfide/carbonate scale precipitation in CO2/H2S corrosion. Weight gain/loss (WGL) method was used to investigate the scale formation using X65 carbon steel as substrates. Scanning Electron Microscopy (SEM/EDS), X-ray Diffraction methodology (XRD), X-ray Photoelectron Spectroscopy (XPS), and Electron Pr...
