Book: Facts and Fallacies of Software Engineering
This week I read the book Facts and Fallacies of Software Engineering by Robert L. Glass, in preparation for attending a new meetup devoted to discussing classic books about software development. The author opines that the information in the book … Continue reading
Implementing the Efficient Matrix Solution for Special Classes of Engineering Problems
Yesterday I described how to set up a matrix for efficient solution, today I’ll describe how to actually execute the solution. I plan to go back and revisit the intermediate steps but I wanted to show how this series of … Continue reading
How My Core Competencies Map To Working With Customer Systems
I created the figure below while I was working out the requirements for a simulation tool that would support analysis of this kind of system. While this diagram represents a fairly specific example of the set of things I’ve been … Continue reading

Context for the Graph Project
A friend asked me what my recent series of posts is trying to communicate, so here is a brief rundown. When not writing here about my previous experience or reactions to things I’ve seen or read, the goal is to … Continue reading
Checking My Steam Table Functions
While I was working out a steam table page yesterday I found it necessary to graph the functions out as a means of verifying them. Here’s the first graph I created in JavaScript. It shows not only the curve of … Continue reading

Steam Tables (and Thermodynamic Properties of Fluids In General)
A little while ago I was ruminating on the subject of needing to know the thermodynamic properties of materials before you could do simulations of those materials. I therefore figured I’d spend the week dusting off some old functions I’d … Continue reading

Simulation: Continuing Yesterday’s Analysis
Yesterday I analyzed some of the considerations involved in modeling a section of a petrochemical refining process, namely that of hydrodesulfurization. That is adding hydrogen to hydrocarbons containing sulfur in the presence of a catalyst at an elevated temperature so … Continue reading

What Drives The Scale Of A Business Or Simulation System?
The scale of a business or simulation (continuous or discrete-event) system can be driven by a number of factors. Scale can be measured in terms of CPU cycles, communication bandwidth, disk storage, dynamic memory usage, power consumption, and perhaps other … Continue reading

Discrete-Event Simulation: Looking Under The Hood
Yesterday I mentioned a few constructs that a discrete-event simulation system would have to have. They are: A time-ordered future events queue where events are created and entered into the queue, and then processed one by one in time order. … Continue reading
How Timing Works: The Internal Architecture of a Discrete-Event Simulation
On Monday I described the different ways time and events are handled in continuous and discrete-event simulations. Today I want to go into a little more detail about how those things work in a discrete-event simulation because the internal architecture … Continue reading
