It includes a section on computing Fourier series of polynomials. It also includes a link to the freely available student solutions manual.

This article includes a menu of post-reading activities for use with any nonfiction text. Students spend $50 on their choice of activities.

This textbook represents a transformative force in educational pedagogy and publishing, significantly enhancing value for both students and faculty by redefining the creation, distribution, and utilization of educational materials. Advocating for an open, collaborative approach to textbook development, it aims to create a future where educational resources are more accessible, equitable, and responsive to the diverse needs of learners. The content is meticulously organized into 10 structured modules, including two intensive capstone projects, which align with dual-dimensional learning outcomes that meet and surpass specific programmatic ABET accreditation standards. By introducing a novel 3D pedagogical approach and adopting a quasi-Competency-Based Education (CBE) strategy, this textbook moves beyond traditional grading systems, employing digital credentials to assess student mastery. This innovative approach not only enhances learning outcomes but also sets a new standard in educational practices, promising to reshape the educational landscape.

This course was developed in 1987 by the MIT Center for Advanced Engineering Studies. It was designed as a distance-education course for engineers and scientists in the workplace.
Advances in integrated circuit technology have had a major impact on the technical areas to which digital signal processing techniques and hardware are being applied. A thorough understanding of digital signal processing fundamentals and techniques is essential for anyone whose work is concerned with signal processing applications.
Digital Signal Processing begins with a discussion of the analysis and representation of discrete-time signal systems, including discrete-time convolution, difference equations, the z-transform, and the discrete-time Fourier transform. Emphasis is placed on the similarities and distinctions between discrete-time. The course proceeds to cover digital network and nonrecursive (finite impulse response) digital filters. Digital Signal Processing concludes with digital filter design and a discussion of the fast Fourier transform algorithm for computation of the discrete Fourier transform.

This expository article for elementary students describes the dinosaurs that lived in polar regions as well as the adaptations that helped them survive in the dark and cold environment. Modified versions for younger grades are available.

Direct Energy Conversion discusses both the physics behind energy conversion processes and a wide variety of energy conversion devices. A direct energy conversion process converts one form of energy to another through
a single process. The first half of this book surveys multiple devices that convert to or from electricity including piezoelectric devices, antennas, solar cells, light emitting diodes, lasers, thermoelectric devices, and batteries.
In these chapters, physical effects are discussed, terminology used by engineers in the discipline is introduced, and insights into material selection is studied. The second part of this book puts concepts of energy conversion
in a more abstract framework. These chapters introduce the idea of calculus of variations and illuminate relationships between energy conversion processes.

This peer-reviewed book is used for a junior level electrical engineering class at Trine University. However, it is intended not just for electrical engineers. Direct energy conversion is a fascinating topic because it does not fit neatly into a single discipline. This book also should be of interest to physicists, chemists, mechanical engineers, and other researchers interestedin an introduction to the energy conversion devices studied by scientists and engineers in other disciplines

Students disassemble and analyze retractable pens. Through the process of "reverse engineering," they learn how the ink pens work.

Whether caused by acts of nature, human error or even malevolence, disasters are an increasingly costly threat. The National Science Foundation works with the Administration and other federal agencies in a coordinated effort to anticipate disasters and minimize their effects. Research projects provide information on understanding the causes and predicting natural disasters, disaster preparation in the form of stronger buildings, infrastructure and cybersecurity, and disaster response.

Students discover the mathematical constant phi, the golden ratio, through hands-on activities. They measure dimensions of "natural objects"—a star, a nautilus shell and human hand bones—and calculate ratios of the measured values, which are close to phi. Then students learn a basic definition of a mathematical sequence, specifically the Fibonacci sequence. By taking ratios of successive terms of the sequence, they find numbers close to phi. They solve a squares puzzle that creates an approximate Fibonacci spiral. Finally, the instructor demonstrates the rule of the Fibonacci sequence via a LEGO® MINDSTORMS® NXT robot equipped with a pen. The robot (already created as part of the companion activity, The Fibonacci Sequence & Robots) draws a Fibonacci spiral that is similar to the nautilus shape.

In this lesson, students will learn how cosmic rays were discovered and what they are - including their size and speed. Includes background information for the teacher, questions, activities and information about student preconceptions. This is lesson 1 of 4 from "The Cosmic Ray Telescope for the Effects of Radiation (CRaTER)."

This is an activity about the Hubble Deep Field image, an observation of one small area of sky that contained no previously-detected objects. The long time exposure of this image allows us to detect some of the most distant objects seen in our Universe. Learners will view an image of the Hubble Deep Field and identify how many distant galaxies are visible as well as the types of galaxies they might be. Observations will be taken a step further to infer predominant age of a galaxy and determine if there are any trends in age (color) versus galaxy size or type and, ultimately, if the distant Universe appears relatively uniform. This activity is Astronomy Activity 4 in a larger resource, titled "Space Update."

Students learn about biomimicry and the engineering design process as they design and build model ptarmigan feet.

Students explore the concept of optical character recognition (OCR) in a problem-solving environment. They research OCR and OCR techniques and then apply those methods to the design challenge by developing algorithms capable of correctly "reading" a number on a typical high school sports scoreboard. Students use the structure of the engineering design process to guide them to develop successful algorithms. In the associated activity, student groups implement, test and revise their algorithms. This software design lesson/activity set is designed to be part of a Java programming class.

This is an online lesson which introduces the concept of astronomical filters and their connections to imaging different objects in space. Learners will explore perceptions of images as seen using different colors of light, construct a filter wheel, and practice investigating various astronomical images using the filter wheel. This material was designed to highlight how filters are useful to astronomers and show how a real astronomical telescope uses filters to image the Sun.

IDS.900 Doctoral Seminar in Engineering Systems examines the core theory and contextual applications of the emerging field of Engineering Systems. There is a focus on doctoral–level analysis of scholarship on key concepts such as complexity, uncertainty, fragility, and robustness, as well as a critical look at the historical roots of the field and related areas such as systems engineering, systems dynamics, agent modeling, and systems simulations. Contextual applications of the course range from aerospace to technology implementation to regulatory systems to large–scale systems change. Special attention is given to the interdependence of social and technical dimensions of engineering systems.
