Automating Manufacturing Systems with PLCs.pdf

November 9, 2009 · Filed Under Mechanical & Industrial Engineering · Comment  · Tags: , , ,

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.

Taken from Why Use PLC: The softwiring advantage provided by programmable controllers is tremendous. In fact, it is one of the most important features of PLCs. Softwiring makes changes in the control system easy and cheap. If you want a device in a PLC system to behave differently or to control a different process element, all you have to do is change the control program. In a traditional system, making this type of change would involve physically changing the wiring between the devices, a costly and time-consuming endeavor.

Behavioral Genetics - An introduction to how genes and environments interact through development to shape differences in mood, personality, and intelligence.pdf

Taken from Introduction: Why do humans range so widely in their susceptibility to mental illness, in their willingness to take risks, and in their performance on intelligence tests? One answer to this question comes from scientists in the field of behavioral genetics. They say that the variation in behavioral traits across a population is due, in part, to the genes. So many studies have pointed to connections between genes and particular behaviors that most scientists now feel comfortable stating that there is such a link for every possible behavior. But what does it really mean to say that there is a link between genes and behavior?
Does it mean that there is a gene that makes some of us blush when embarrassed; that there is one gene that makes you prefer classical music and another gene that makes you dislike it; that there is a bunch of genes that each provides for different levels of skill in playing poker? The answer to all these questions is no. Does it mean behavior passes down from generation to generation, i.e., is inherited, just like baldness and eye color? Again, the answer is no.
So when next you see an article that proclaims, “Gene for [insert a human behavior here] discovered,” read it with a critical eye. Or when you next hear someone say, “He inherited his [insert a human behavior here] from his father,” receive that with skepticism, too.
The pervasive role of genes in behavior does not mean what it is commonly misunderstood to mean. It does not mean that a gene or even several genes can make you act in any particular way. It does not mean that a behavior can “pass down through the genes.” Such claims are not accepted in behavioral genetics.
It does mean that genes play a vital role in the body’s development and physiology, and it is through the body, acting in response to and upon surrounding environments, that behavior manifests itself. So while we do inherit our genes, we do not inherit behavior traits in any fixed sense. The effect of our given set of genes on our behavior is entirely dependent upon the context of our life as it unfolds day to day.

Fundamentals of Die Casting Design.pdf

November 7, 2009 · Filed Under Mechanical & Industrial Engineering · Comment  · Tags: , , , ,

Taken from Abstract: Die-casting engineers have to compete not only with other die-casting companies, but also against other industries such as plastics, and composite materials. Clearly, the ”black art” approach, which has been an inseparable part of the engineer’s tools, is in need of being replaced by a scientific approach. Excuses that “science has not and never will work” need to be replaced with “science does work”. All technologies developed in recent years are described in a clear, simple manner in this book. All the errors of the old models and the violations of physical laws are shown. For example, the “common” pQ2 diagram violates many physical laws, such as the first and second laws of thermodynamics. Furthermore, the “common” pQ2 diagram produces trends that are the opposite of reality, which are described in this book.
The die casting engineer’s job is to produce maximum profits for the company.
In order to achieve this aim, the engineer must design high quality products at a minimum cost. Thus, understanding the economics of the die casting design and process are essential. These are described in mathematical form for the first time in this volume. Many new concepts and ideas are also introduced. For instance, how to minimize the scrap/cost due to the runner system, and what size of die casting machine is appropriate for a specific project.
The die-casting industry is undergoing a revolution, and this book is part of it. One reason (if one reason can describe the situation) companies such as Doehler Jorvis (the biggest die caster in the world) and Shelby are going bankrupt is that they do not know how to calculate and reduce their production costs. It is my hope that die-casters will turn such situations around by using the technologies presented in this book. I believe this is the only way to keep the die casting professionals and the industry itself, from being “left in the dust.”
