Signals and Systems
Richard Baraniuk et al. · Rice University
This textbook introduces signals and systems in both continuous and discrete time, covering signal operations, system properties, convolution, and stability. It explores Fourier series and transforms, sampling and reconstruction, and system analysis using Laplace and Z-transforms. Advanced topics include filter design, FFT, and matched filtering. Appendices review linear algebra, Hilbert spaces, and analysis fundamentals, with support for interactive content.

Relational Databases and Microsoft Access
Ron McFadyen · University of Winnipeg
This text is a free introductory text that introduces MS Access and relational database design. The motivation is to support a second-year course on database systems which, to the student, is either a service course providing an introduction to database concepts, or, as a prerequisite for more advanced study in the field.

All Things Flow - Fluid Mechanics for the Natural Sciences
Bill Smyth · Oregon State University
This book on fluid mechanics is concerned with phenomena that we have all been familiar with since childhood: flows you see in sinks and bathtubs, in rivers, and at the beach. Prerequisites include basic linear algebra, differential and integral calculus and Newton’s laws of motion. As we go along we discover the need for the more advanced tools of tensor analysis.

Operational Amplifiers & Linear Integrated Circuits
James M. Fiore · Mohawk Valley Community College
The goal of this text, as its name implies, is to allow the reader to become proficient in the analysis and design of circuits utilizing modern linear ICs. It progresses from the fundamental circuit building blocks through to analog/digital conversion systems. The text is intended for use in a second year Operational Amplifiers course at the Associate level, or for a junior level course at the Baccalaureate level.

Slurry Transport
Sape A. Miedema · Delft University of Technology
In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. The book covers horizontal transport of settling slurries (Newtonian slurries). Non-settling (non-Newtonian) slurries are not covered.

Electromagnetic Field Theory: A Problem Solving Approach
Markus Zahn · Massachusetts Institute of Technology
This text is an introductory treatment on the junior level for a two-semester electrical engineering course starting from the Coulomb-Lorentz force law on a point charge. The theory is extended by the continuous superposition of solutions from previously developed simpler problems leading to the general integral and differential field laws. Often the same problem is solved by different methods so that the advantages and limitations of each approach becomes clear.

Complex Analysis - A Visual and Interactive Introduction
Juan Carlos Ponce Campuzano · University of Queensland
The study of complex analysis is important for students in engineering and the physical sciences and is a central subject in mathematics. In addition to being mathematically elegant, complex analysis provides powerful tools for solving problems that are either very difcult or virtually impossible to solve in any other way. In this book you will find examples, problems and applets that allow you to explore complex analysis by using the visual interactive power of the computer (or tablet).

Introduction to Control Systems
Kamran Iqbal · University of Arkansas at Little Rock
A control system manages, commands, directs, or regulates the behavior of other devices or systems using control loops. It can range from a single home heating controller using a thermostat controlling a domestic boiler to large industrial control systems which are used for controlling processes or machines. The control systems are designed via control engineering process.
