How to recognize symptoms of PTSD?
Ron's Response:
Recognizing the symptoms of PTSD early is essential for taking action and finding support. PTSD can deeply affect many aspects of life, and if left untreated, it can lead to complications like depression, substance abuse, and ev
...We ask Russ:
What are the pros for first-principles models?
Russ' Response:
Earlier I shared that I typically classify models as empirical or phenomenological.
In phenomenological models, the mathematical functions are grounded in a mechanistic relation. These models could be termed rigoro
...We ask Greg:
What role do you see dynamic simulation playing in the future of best crystallizer temperature control?
Greg's Response:
Batch-operated stirred cooling crystallizers are the most common type in the industry, but they tend to yield poor quality, primarily due to the high cooling
...We ask Ron:
What impact does PTSD have on manufacturing operations?
Ron's Response:
While PTSD is often linked to severe injuries or loss of life, I will address both PTSD and PTS, focusing on the often overlooked mental health challenges that can arise from less severe but still traumatic
...We ask Russ:
What are the pros for empirical models?
Russ' Response:
I would broadly classify models as empirical or phenomenological. Â
Empirical models are developed by matching flexible mathematical functions to data. Â The functions might be neural networks, or classic statistical power
...We ask Julie:
How has simulation contributed to operator training and control strategy development in your organization?
Julie's Response:
Many years ago, one site had an incident where an interruption in the flow of an organic fuel led to a deflagration. As a result, the operators always r

What role do you see dynamic simulation playing in the future of best dryer temperature control?
Greg's Response:
The basic loop arrangement for dryer temperature control would use cascade control of outlet temperature to set inlet temperature. However, a constant outlet temper

Why use phenomenological models based on first principles over data-based modeling options?
Russ' Response:
I would broadly classify models as empirical or phenomenological.
Empirical models are developed by matching flexible mathematical functions to data. Â The functions migh

How do focus and stress management enhance problem-solving?
Ron's Response:
In high-pressure situations, even the best technical knowledge is of little use without focus and the ability to manage stress effectively. Simulation training helps operators develop these essential sk
