Open-Channel Hydraulics Overview This course is for Civil Engineers, Sanitary Engineers or any Engineers who might deal with open-channel flow. No prior knowledge of open channel flow is needed; however basic algebra and trigonometry will be used in the course. The course introduces you to hydraulic elements of open-channels. An introduction to types of flow and fundamental equations used for open-channels is also  more...

Variable Frequency Drives I wrote this courses with the intention of showing how the various parts of a Variable Frequency Drive (VFD) work and how they are integrated to make an operating system. It starts with a review of AC and DC theory that is applicable to the way that an Inverter (another name given to VFD? s) works. An explanation is given of how the various solid state electronic components work. This course then  more...

Electrical Components - What They Are How They Work and What They Look Like on Drawings I wrote this course with the intention of showing engineers in all disciplines how to recognize drawings of a variety of common electrical components. This is, by no means, a complete list. A task of that magnitude would be almost impossible. I have selected, however, those components that I have used the most in my career. I did start with a review of the three basic elements from which most  more...

AC Waveforms Basic Quantities for Non-Electrical Engineers Overview This course introduces basic definitions, quantities and concepts associated with the AC waveforms. The material is mainly intended for the non-electrical engineer who requires a basic understanding of AC electricity. Electrical engineers who have worked a considerable time in other areas will also find the course useful. The course material is presented in an illustrative manner  more...

Programmable Logic Controllers I wrote this course with the intention of showing how Programmable Logic Controller systems are constructed, and how to get started on programming these systems. After taking this class, an engineer should be able to design and build a simple PLC controller. This course was designed for electrical engineers with limited experience with PLC? s as well as engineers of other disciplines. Most  more...

Industrial Sensors and How They Work This course was written with the intention of showing engineers in all disciplines how to think about and apply standard electrical sensors. This is, by no means, a complete list. A task of that magnitude would be almost impossible. I have selected, however, those sensors that I have used the most in my career. The course starts by covering temperature sensors. This is followed by force measure  more...
