Interactivity and in-line review questions enables students to rapidly examine system tradeoffs and design alternatives. Interactive graphics allow the students to engage with and visualize communication systems concepts. Systems trade-offs, including link budgets, are emphasized. Traditional analog modulation systems are also described. Double-sideband suppressed carrier modulation and quadrature modulation then provide the foundation for the discussions of Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-ary Quadrature Amplitude Modulation (M-QAM), M-ary Phase Shift Keying (MPSK), and the basic theory of Orthogonal Frequency Division Multiplexing (OFDM). The material opens with describing the transformation of bits into digital baseband waveforms. This ebook provides a unique pedagogical approach to teaching the fundamentals of communication systems using interactive graphics and in-line questions.

Introduction to Communication Systems: An Interactive Approach Using the Wolfram Language This compilation is drafted from notes used in the course Intermediate Fluid Mechanics, offered to seniors and first year graduate students who have a background in mechanical engineering or a closely related area. Finally we will explore the complexities of turbulent flows and how for boundary layer flows one can predict drag forces. We will also examine some of the exact solutions of the Navier-Stokes equations based on classical fluid mechanics.

We will see applications to aerodynamics, with analysis methods able to determine forces on arbitrary bodies.

It is not meant to be an in-depth study of potential flow or viscous flow, but is meant to expose students to additional analysis techniques for both of these categories of flows. Students are expected to have some background in some of the fundamental concepts of the definition of a fluid, hydrostatics, use of control volume conservation principles, initial exposure to the Navier-Stokes equations, and some elements of flow kinematics, such as streamlines and vorticity. This book is meant to be a second course in fluid mechanics that stresses applications dealing with external potential flows and intermediate viscous flows.
