It isn't that they can't see Approach your problems from the solution. the right end and begin with It is that they can't see the the answers. Then one day, problem. perhaps you will find the final qu~stion. G. K. Chesterton.

Physical Models and Equilibrium Methods in Programming and Economics
The Scandal of Father Brown ITh~ Point of 'The Hermit Clad in Crane Feathers' in R. van Gulik's a Pin'. The Chinese Maze Murders. Growing specialization and diversification have brought a host of monographs and textbooks on increasingly specialized topics. HowQvQr, thQ "tree" of knowledge of mathematics and related field does not grow only by putting forth new branches. It also happ~ns, quit~ often in fact, that branches which were thought to be completely disparate are suddenly seen to be related. Further, the kind and level of sophistication of mathe­ matics applied in various sciences has changed drastically in recent years: measure theory is used (non-trivially) in regional and theoretical economics; algebraic geometry interacts with physics; the Minkowsky lemma, coding theory and the structure of water meet one another in packing and covering theory; quantum fields, crystal defects and mathematical programming profit from homotopy theory; Lie algebras are relevant to filtering; and prediction and electrical engineering can use Stein spaces.

Beginning Perl by Simon Cozens
Wrox Press | May 25 2000 | ISBN: 1861003145 | Pages: 700 | PDF | 3.94 MB
Perl is an immensely popular scripting language that combines the best features of C, key UNIX utilities and a powerful use of regular expressions. It has a wide range of uses beyond simple text processing and is commonly used for web programming – creating and parsing CGI forms, validating HTML syntax and hyperlinks – as well as e-mail and Usenet news filtering. Perl is increasingly the system administrator's scripting language of choice and is used for file and directory manipulation, database access and a whole range of daily system operator chores.

Optimal Control, 2nd edition By Frank L. Lewis, Vassilis L. Syrmos
1995 | 560 Pages | ISBN: 0471033782 | PDF | 14 MB

Optimal Control, 2nd edition
This new, updated edition of Optimal Control reflects major changes that have occurred in the field in recent years and presents, in a clear and direct way, the fundamentals of optimal control theory. It covers the major topics involving measurement, principles of optimality, dynamic programming, variational methods, Kalman filtering, and other solution techniques. To give the reader a sense of the problems that can arise in a hands-on project, the authors have included new material on optimal output feedback control, a technique used in the aerospace industry. Also included are two new chapters on robust control to provide background in this rapidly growing area of interest. Relations to classical control theory are emphasized throughout the text, and a root-locus approach to steady-state controller design is included. A chapter on optimal control of polynomial systems is designed to give the reader sufficient background for further study in the field of adaptive control.

The authors demonstrate through numerous examples that computer simulations of optimal controllers are easy to implement and help give the reader an intuitive feel for the equations. To help build the reader's confidence in understanding the theory and its practical applications, the authors have provided many opportunities throughout the book for writing simple programs.

Optimal Control will also serve as an invaluable reference for control engineers in the industry. It offers numerous tables that make it easy to find the equations needed to implement optimal controllers for practical applications. All simulations have been performed using MATLAB and relevant Toolboxes.

Optimal Control assumes a background in the state-variable representation of systems; because matrix manipulations are the basic mathematical vehicle of the book, a short review is included in the appendix.

A lucid introductory text and an invaluable reference, Optimal Control will serve as a complete tool for the professional engineer and advanced student alike.

As a superb introductory text and an indispensable reference, this new edition of Optimal Control will serve the needs of both the professional engineer and the advanced student in mechanical, electrical, and aerospace engineering. Its coverage encompasses all the fundamental topics as well as the major changes of recent years, including output-feedback design and robust design. An abundance of computer simulations using MATLAB and relevant Toolboxes is included to give the reader the actual experience of applying the theory to real-world situations. Major topics covered include:
* Static Optimization
* Optimal Control of Discrete-Time Systems
* Optimal Control of Continuous-Time Systems
* The Tracking Problem and Other LQR Extensions
* Final-Time-Free and Constrained Input Control
* Dynamic Programming
* Optimal Control for Polynomial Systems
* Output Feedback and Structured Control
* Robustness and Multivariable Frequency-Domain Techniques
