A Hierarchical Constrained Reinforcement Learning for Optimization of Bitumen Recovery Rate in a Primary Separation VesselDownload
Shafi, Hareem, Velswamy, Kirubakaran, Ibrahim, Fadi, Huang,Biao
This work proposes a two-level hierarchical constrained control structure for reinforcement learning (RL) with application in a Primary Separation Vessel (PSV). The lower level is concerned with servo tracking and regulation of the interface level against variances in ore quality by manipulating...
A Long-Short Term Memory Recurrent Neural Network Based Reinforcement Learning Controller for Office Heating Ventilation and Air Conditioning SystemsDownload
Yuan wang, Kirubakaran Velswamy, Biao Huang
Energy optimization in buildings by controlling the Heating Ventilation and Air Conditioning (HVAC) system is being researched extensively. In this paper, a model-free actor-critic Reinforcement Learning (RL) controller is designed using a variant of artificial recurrent neural networks called...

Understanding the influence of rapid solidification conditions on the formed microstructure is important to determine how process conditions affect the final mechanical properties. In this work the rapid solidification of hypoeutectic and hypereutectic Al-xSi (x=10wt. %, 18wt %) alloys was...

A non-ideal osmotic equilibrium equation is proposed as a replacement for the Boyle van’t Hoff equation to describe the equilibrium volume of a living cell as a function of external osmolality. Contrary to common understanding, the Boyle van’t Hoff equation is only valid for ideal, dilute...

This paper investigates amorphous phase formation and rapid solidification characteristics of a CoCr alloy. High cooling rate and high undercooling-induced rapid solidification of the alloy was achieved by impulse atomization in helium atmosphere. Two atomization experiments were carried out to...

The multisolute osmotic virial equation is the only multisolute thermodynamic solution theory that has been derived from first principles and can make predictions of multisolute solution behaviour in the absence of multisolute solution data. Other solution theories either (i) include simplifying...
Assessment of Oxide Descaler Functionality in a Steel Hot Rolling Mill Using Infrared Video ImagingDownload
Wiskel, J.B., Linchieh, A., Henein, H.
A series of infrared temperature videos were taken of the upper surface of hot rolled microalloyed steel skelp immediately following laminar cooling. In addition to validation of the skelp temperature and skelp cooling patterns, local temperature minimums were observed in the infrared images....
CHARACTERIZATION OF X80 AND X100 MICROALLOYED PIPELINE STEEL USING QUANTITATIVE X-RAY DIFFRACTIONDownload
Wiskel, J.B., Li, X., Ivey, D.G., Henein, H.
Quantitative X-ray diffraction characterization of four (4) X80 and three (3) X100 microalloyed steels was undertaken. The effect of through thickness position, processing parameters and composition on the measured crystallite size, microstrain and J index (relative magnitude of crystallographic...
Mohammadijoo, M., Collins, L., Henein, H., Ivey, D.G.
Pipeline failures can be severe events that impact both society and industry. The oil spills in North Battleford, Saskatchewan in 2016 and the gas rupture in Beardmore, Ontario in 2011 are examples of recent pipeline failures in Canada. Pipeline failures have led to pipe fabricators developing...
