Physics underlies all complexity, including our own existence: how
is this possible? How can our own lives emerge from interactions of
electrons, protons, and neutrons? This book considers the
interaction of physical and non-physical causation in complex
systems such as living beings, and in particular in the human
brain, relating this to the emergence of higher levels of
complexity with real causal powers. In particular it explores the
idea of top-down causation, which is the key effect allowing the
emergence of true complexity and also enables the causal efficacy
of non-physical entities, including the value of money, social
conventions, and ethical choices.
George Ellis was one of the premier English writers on carpentry
and joinery. This, the author's last book, was originally issued in
two volumes; the present edition is a reprint of the 1932
one-volume edition.
The trade of wooden stairbuilding has enjoyed a rebirth during
the last ten years. Unfortunately, most trade schools do not teach
this complex craft, and there has been little published in the
field for many years. This leaves the craftsman at a loss, both for
available information and training.
George Ellis has written a very lucid book on the subject. He
covers much the same ground as Alexander Mowat in A Treatise on
Stairbuilding and Handrailing (page 92), but Ellis is much less
technical and more shop oriented. He includes detailed information
on taking dimensions and setting out stairs (geometric, spiral, and
elliptical), newels, balusters, brackets; constructing soffit
linings, single and geometric handrailings, and wreathed handrail
to spiral stairs; and he explains the cylinder method of making
wreaths.
A classic treatise on the practice of joiners' work by hand and
machine. "A gold mine for woodworkers, architects, and
preservationists". -- Old House Journal
The Chicago Cubs tradition is one built on spectacular losing
streaks and even more spectacular collapses. Yet despite all the
losses and disappointments, an amazing thing happens every summer
at the corner of Addison and Sheffield: millions of fans flock to
Wrigley Field and millions more fans across the country regularly
tune in to watch Cubs games broadcast on television. Exactly why
Cubs fans support their squad with such reckless abandon isn't
entirely clear--these people represent a remarkable aberration of
human psychology, epitomizing the spirit and experience of
dedication to a desperate cause. And the whole time, they're oddly
happy. "The Cubs Fan's Guide to Happiness" reveals what makes Cubs
fans tick and what keeps them happy. It explains why it's not over
until you're mathematically eliminated, why winning really isn't
everything, and why it's perfectly acceptable to blame all your
trouble on a scapegoat--which may or may not be an actual goat. The
fully revised edition also provides educational sidebars, practical
applications, and true words of wisdom from celebrity Cubs fans as
well as surviving the planned renovations to the product on the
field and Wrigley Field itself.
Observers are digital algorithms that combine sensor outputs with
knowledge of the system to provide results superior to traditional
structures, which rely wholly on sensors. Observers have been used
in selected industries for years, but most books explain them with
complex mathematics. This book uses intuitive discussion, software
experiments, and supporting analysis to explain the advantages and
disadvantages of observers. If you are working in controls and want
to improve your control systems, observers could be the technology
you need and this book will give you a clear, thorough explanation
of how they work and how to use them.
Control systems and devices have become the most essential part of
nearly all mechanical systems, machines, devices and manufacturing
systems throughout the world. Increasingly the efficiency of
production, the reliability of output and increased energy savings
are a direct result of the quality and deployment of the control
system. A modern and essential tool within the engineer's kit is
the Observer which helps improve the performance and reduce the
cost of these systems.
George Ellis is the author of the highly successful Control System
Design Guide (2nd Edition). Unlike most controls books, which are
written by control theorists and academics, Ellis is a leading
engineer, designer, author and lecturer working in industry
directly with the users of industrial motion control systems.
Observers in Control Systems is written for all professional
engineers and is designed to be utilized without an in-depth
background in control theory. This is a "real-world" book which
will demonstrate how observers work and how they can improve your
control system.It also shows how observers operate when conditions
are not ideal and teaches the reader how to quickly tune an
observer in a working system.
Software Available on line: A free updated and enhanced version of
the author's popular Visual ModelQ allows the reader to practice
the concepts with Visual ModelQ models on a PC. Based on a virtual
laboratory, all key topics are demonstrated with more than twenty
control system models. The models are written in Visual ModelQ, and
are available on the Internet to every reader with a PC.
* Teaches observers and Kalman filters from an intuitive
perspective
* Explains how to reduce control system susceptibility to noise
* Shows how to design an adaptive controller based on estimating
parameter variation using observers
Shows how to improve a control system's ability to reject
disturbances
* Key topics are demonstrated with PC-based models of control
systems. The models are written in both MatLab(R) and ModelQ;
models are available free of charge

Briefings is a new series of short books to explain and clarify
complex contemporary subjects, written for non-specialists by
experts in their fields. Themes and topics covered will include
Feminism, Education, Cosmology, Medical Ethics, Structuralism,
Quantum Physics and Comparative Religion among others. Before the
Beginning is a radical attempt to explain and redefine the origins
and purpose of creation. Professor Ellis deals clearly and
authoritatively with new scientific theories explaining how things
began and elucidates the laws which control the operation of the
universe. In addition he describes the complex mechanism by which
the laws of physics appear to govern and facilitate, as well as to
sustain human life. His conclusions about the very meaning of life
are often unexpected, but the process by which he reaches them is
illuminating and scientifically sound, as would be expected from
one of the world's foremost cosmologists.
Control Systems Design Guide has helped thousands of engineers to
improve machine performance. This fourth edition of the practical
guide has been updated with cutting-edge control design scenarios,
models and simulations enabling apps from battlebots to solar
collectors. This useful reference enhances coverage of practical
applications via the inclusion of new control system models,
troubleshooting tips, and expanded coverage of complex systems
requirements, such as increased speed, precision and remote
capabilities, bridging the gap between the complex, math-heavy
control theory taught in formal courses, and the efficient
implementation required in real industry settings. George Ellis is
Director of Technology Planning and Chief Engineer of Servo Systems
at Kollmorgen Corporation, a leading provider of motion systems and
components for original equipment manufacturers (OEMs) around the
globe. He has designed an applied motion control systems
professionally for over 30 years He has written two well-respected
books with Academic Press, Observers in Control Systems and Control
System Design Guide, now in its fourth edition. He has contributed
articles on the application of controls to numerous magazines,
including Machine Design, Control Engineering, Motion Systems
Design, Power Control and Intelligent Motion, and Electronic Design
News.
Project Management in Product Development: Leadership Skills and
Management Techniques to Deliver Great Products is written for new
and aspiring project managers in product development. Although
texts on project management are common, the material presented here
is unique, instead focusing on product development, a challenging
segment of project management because of the high level of
uncertainty, the need for a robust set of problem-solving
techniques, and a demand for broad cross-functional teams. The book
also focuses on more than just project management techniques,
including a thorough treatment of transformational and
transactional leadership. Other topics covered include
problem-solving techniques, development, and continuous improvement
of processes required in product development, risk recognition and
management, and proper communication with mangers and other
stakeholders. Finally, project management techniques used in
product development are presented, including the critical path
method, scrum and XP, and Kanban/lean project development, along
with the strengths and weaknesses of each.
