Automating Manufacturing Systems with PLCs.pdf
Taken from PROGRAMMABLE LOGIC CONTROLLERS’s Introduction: Control engineering has evolved over time. In the past humans were the main method for controlling a system. More recently electricity has been used for control and early electrical control was based on relays. These relays allow power to be switched on and off without a mechanical switch. It is common to use relays to make simple logical control decisions. The development of low cost computer has brought the most recent revolution, the Programmable Logic Controller (PLC). The advent of the PLC began in the 1970s, and has become the most common choice for manufacturing controls.
PLCs have been gaining popularity on the factory floor and will probably remain predominant for some time to come. Most of this is because of the advantages they offer: Cost effective for controlling complex systems.
Flexible and can be reapplied to control other systems quickly and easily.
Computational abilities allow more sophisticated control.
Trouble shooting aids make programming easier and reduce downtime.
Reliable components make these likely to operate for years before failure.
Water Resources Engineering.pdf
This course material is addressed to a civil engineering student I suppose, but also so much applies to other disciplines, such as mechanical engineering and geological engineering.
Reactor Physics.pdf
Nuclear reactor physics including chain reactions, reactor statics and kinetics, multigroup analysis, core thermalhydraulics and the impact of these topics on reactor design are covered. Special topics such as xenon dynamics, burnup and reactor flux effects on safety are included.
Nuclear Reactor Analysis.pdf
This is one of the Engineering Physics course material held by nuceng.ca, about introduction to nuclear energy, nuclear physics and chain reactions, reactor statics and kinetics, multigroup analysis, core thermalhydraulics and reactor design.
