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.

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.

Control in an Information Rich World: Report of the Panel on Future Directions in Control, Dynamics, and Systems.pdf

The purpose of this report is to spell out some of the prospects for control in the current and future technological environment, to describe the role the field will play in military, commercial, and scientific applications over the next decade, and to recommend actions required to enable new breakthroughs in engineering and technology through application of control research.

Mining Industry Research Handbook.pdf

August 4, 2009 · Filed Under Mining Engineering · Comment  · Tags: , ,

Taken from Editorial: This Mining Industry Research Handbook comprises the results of the work of the European Thematic Network NESMI, the Network on European Sustainable Minerals Industries. A total of 43 members and about 70 so-called associated members (partners not receiving any funding) worked together for 3 years from April 1st 2002 until March 31st 2005. Their main objective was to concentrate forces in the European mining and processing fields in order to make a significant step forward towards sustainable raw material supply in Europe.
