Everything in a BUKH is created for a long life in seawater and it can be run at full speed for any length of time. Starter motor, alternator, oil filter, stop magnet and water pump are placed high up on the engine so that they are easily accessible and prevents bilge water, if any, from causing possible damage. An easily replaceable zinc anode prevents the vital parts of the engine from being damaged by galvanic corrosion.

Discovering Artificial Economics - How Agents Learn and Economies Evolve.pdf

November 10, 2009 · Filed Under Finance · Comment  · Tags: ,

Taken from Preface: We live in an astonishingly complex world. Yet what we do in our everyday lives seems simple enough. Most of us conform to society’s rules, pursue familiar strategies, and achieve reasonably predictable outcomes. In our role as economic agents, we simply peddle our wares and earn our daily bread as best we can.
So where on earth does this astonishing complexity come from? Much of it is ubiquitous in nature, to be sure, but part of it lies within and between us. Part of it Comes from those games of interaction that humans play-games against nature, games against each other, games of competition, games of cooperation. In bygone eras, people simply hunted and gathered to come up with dimer.
Today you can find theoretical economists scratching mysterious equations on whiteboards (not even blackboards) and getting paid to do this. In the modern economy, most of us make our living in a niche created for us by what others do. Because we’ve become more dependent on each other, our economy as a whole has become more strongly interactive.
A strongly interactive economy can behave in weird and wonderful ways, even when we think we understand all its individual parts. The resulting path of economic development is packed with unexpected twists and turns, reflecting the diversity of decisions taken by different economic agents. But an understanding of economic outcomes requires an understanding of each agent’s beliefs and expectations and the precise way in which the agents interact.
In a strongly interactive economy, the cumulative pattern of interactions can produce unexpected phenomena, emergent behavior that can be lawful in its own right. Yet this is far from obvious if we study economics.

Taken from Preface: This report was prepared by Guy Carpenter & Company, Inc. in conjunction with Dr. Robert Blaunstein, National Director of Loss Control and Underwriting Manager for American Safety Insurance Company. Previously, Dr. Blaunstein was Managing Director and co-founder of Seneca Environmental Management (SEM), Vice President of Seneca Specialty Company and Vice President of Crum and Forster Specialty Insurance Company. While Assistant Professor of Physics at the University of Tennessee and consulting scientist to the Oak Ridge National Laboratory, Dr. Blaunstein conducted research, provided instruction and supervised doctoral students in the area of atomic and molecular radiation physics. A frequent lecturer and consultant to governmental and industrial leaders throughout the world, Dr. Blaunstein was a Public Health Service Fellow and member of the United States Chamber of Commerce, Environment Committee and is a member of the American Physical Society, The American Society of Testing and Materials, National Groundwater Association and the Sigma Xi Honorary Society. He received his Ph.D. in physics from the University of Tennessee and an M.S. degree in physics from Case Western Reserve University.

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.

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.”
