An AP Research Paper Improving Faucet Efficiency through the optimization of laminar flow through annular pipe. Conclusion Summary: Study results support that the most optimal faucet profile is one that utilizes an annulus, of which the internal and external geometries are both circular. It was also observed that the average laminar efficiency of a faucet increased dramatically as the internal radius approached the external radius. Hence, it can be concluded that the larger the internal radius is, the more laminar efficient it becomes. This signifies a positive correlation between the size of the internal radius and its associated average laminar efficiency. Thus, it was determined ...

In Search of Simulacra - Modeling a Self Learning Android is a book written for those interested in Artificial Intelligence and where it could lead. This book is written in plain language and it’s only prerequisite is an interest in Artificial Intelligence. The first few chapters takes the reader through a basic understanding of human nature, thinking, learning and problem solving. The book then presents possibilities of how a self-learning Android could work. From there, conceptual information about basic control systems through to Artificial Neural Networks and other software architectures is presented. All in plain language. The rest of the book goes on to explain, again in plain lang ...

This book is a set of class lecture notes and worked example problems developed for use in an undergraduate introductory Mechanics-Dynamics course for Mechanical, Aerospace and other engineers. The topics include kinematics and kinetics of particles and rigid bodies, work-energy methods and impulse-momentum concepts. The author is Dr. John L. Turner, currently an adjunct professor at the University of Arizona.

The "aha moment" for the awesome energy of wood followed an historic ice storm in 2007 that crushed huge swaths of the tree canopy across Southwest, Missouri. Traveling to clear the damage as gas prices jumped, seeing the smile on the face of my eight year old son in his first experience with a 4-wheeler, I began pondering his energy future. Putting a pencil to the btu energy we cut into the ground to rot, the numbers did not add up to sanity. We used expensive energy, to waste free energy to the tune of almost the average selling price per acre. In my energy past, two dollars bought ten gallons of gas. Local farm work paid two dollars per hour. A road worthy fixer upper vehicl ...

This book is written for people who wish to learn MATLAB for the first time. The book is really designed for beginners and students. In addition, the book is suitable for students and researchers in various disciplines ranging from engineers and scientists to biologists and environmental scientists. One of the objectives of writing this book is to introduce MATLAB and its powerful and simple computational abilities to students in high schools. The material presented is very easy and simple to understand - written in a gentle manner. The topics covered in the book include arithmetic operations, variables, mathematical functions, complex numbers, vectors, matrices, programming, graphs, sol ...

This is a set of lecture notes and worked example problems for use in an introductory course in mechanics of materials. It can serve as a primary text or as a supplement to another class text. It includes detailed discussions and illustrations of the fundamental principles of the usual topics of mechanics of materials (stress, strain, Hookes Law, axial, torsional and bending loading, beam deflections, failure theories and a brief intro to buckling of long bars). Emphasis is placed on a thorough coverage of stress and strain at a point and building a foundation for more advanced topics including finite elements and energy methods in mechanics. Dr. John L. Turner is an adjunct professor at ...

Many modelers of ion-exchange thermodynamics have assumed that the selectivity of two ions within a ternary system could be modeled from data gained from the associated binary systems. The heart of this assumption is that the third ion has no synergistic interactions with the other ions in the solid phase, but rather influences the exchange solely by diluting the concentration of other ions on the solid. Here, a method to detect synergism between solid-phase ions is reported. The method developed employs Log Contrast models and the statistical F Test. The Log Contrast models use mole ratios rather than mole fractions as inputs because mole ratios are not subject to the mixture constr ...

A documentary novel following Old Cheap, a cross-country hero who took America by storm leaving behind fractured remnants. Through these remnants the life and legend are explored.

Want to design your own PCBs? Don't know where to start? This book's got you covered! It's a manual on how to think about where the parts go, not just what mouse moves to do. It is aimed specifically at someone who wants to convert a schematic diagram into a practical printed circuit board. The design process is explained from schematic parts all the way down to optimizing placement and routing. The most recent edition here includes not only through-hole parts but also extension to surface mount part layout. The author has designed PCBs for decades. You can do it too!
