This eBook was written as the sequel to the eBook titled DC Circuits, which was written in 2016 by Chad Davis.
This eBook covers Alternating Current (AC) circuit theory as well us a brief introduction of electronics. It is
broken up into seven modules. Module 1 covers the basic theory of AC signals. Since only DC sources are used in
the first eBook, details of AC signals such as sinusoidal waveforms (or sine waves), square waves, and triangle
waves are provided. Module 2, titled AC Circuits Math Background, covers the mathematics background needed
for solving AC circuit problems. The background material in Modules 1 and 2 are combined in Module 3 to solve
circuits with AC sources that include resistors, inductors, and capacitors (RLC circuits).

In this professional development session, we will develop a shared understanding of how formative assessment works and different approaches that have been developed. The material for this resource come from a series of PD sessions on formative assessment developed by the ACESSE team: Philip Bell, Shelley Stromholt, Bill Penuel, Katie Van Horne, Tiffany Neill, and Sam Shaw.We will be updating this Facilitator's Guide for ACESSE Resource A with the most up-to-date information about this resource over time.

Abstract: This session provides a step-by-step process to support participants as they design a 3D assessment task for the science classroom. Along the way, they learn how to define 3D learning performances for specific lessons—and how to use a range of tools to support their assessment design work. A key goal of the session activity is to improve the connection of intended learning goals to assessment practices. Participants build their 3D assessment design capacity by designing and workshopping tasks—before piloting them in their classrooms. The approaches learned in this workshop can be used with any curricula, at any grade level, and across all subjects of science. 

Overview: In this workshop, we will build our capacity to identify the range of intellectual resources students use as they make sense of phenomena. We will first explore how equity and justice relate to culture-based approaches to pedagogy—and then focus on how to identify and leverage the resources students use in moments of sensemaking. This resource can also be used by individuals wanting to learn how equity involves promoting the rightful presence of all students across scales of justice, desettling inequities, and supporting expansive learning pathways. This workshop provides participants with an opportunity to explore important theoretical ideas by exploring examples of how learners engage in diverse sense-making. Participants will learn about some of the challenges that less expansive learning environments can cause for learners from non-dominant communities. This resource is estimated to take between 161-268 minutes (2 ⅔ - 4 ¾ hours), depending on the choices of the facilitator in scenario selection.

An essential and practical text for both students and teachers of AC electrical circuit analysis, this text picks up where the companion DC electric circuit analysis text leaves off. Beginning with basic sinusoidal functions, ten chapters cover topics including series, parallel, and series-parallel RLC circuits. Numerous theorems and analysis techniques are examined including superposition, Thévenin's theorem, nodal and mesh analysis, maximum power transfer and more. Other important topics include AC power, resonance, Bode plots and an introduction to three-phase systems. Each chapter begins with a set of chapter objectives and includes a summary and review questions. A total of over 500 end-of-chapter exercises are included. A companion laboratory manual is available.

This course introduces the basic components of an airframe structure and discusses their use and limitations. The realities of composite design such as the effect of material scatter, environmental knockdowns, and damage knockdowns are discussed and guidelines accounting for these effects and leading to robust designs are presented.

The resulting design constraints and predictive tools are applied to real-life design problems in composite structures. A brief revision of lamination theory and failure criteria leads into the development of analytical solutions for typical failure modes for monolithic skins (layup strength, buckling under combined loads and for a variety of boundary conditions) and stiffeners (strength, column buckling under a variety of loads and boundary conditions, local buckling or crippling for one-edge and no-edge-free conditions). These are then combined into stiffened composite structures where additional failure modes such as skin-stiffener separation are considered. Analogous treatment of sandwich skins examines buckling, wrinkling, crimping, intra-cellular buckling failure modes. Once the basic analysis and design techniques have been presented, typical designs (e.g. flange layup, stiffness, taper requirements) are presented and a series of design guidelines (stiffness mismatch minimization, symmetric and balanced layups, 10% rule, etc.) addressing layup and geometry are discussed. On the metal side, the corresponding design practices and analysis methods are presented for the more important failure modes (buckling, crippling) and comparisons to composite designs are made. A design problem is given in the end as an application of the material in this Part of the course.

This course is designed to introduce students who wish to specialize in stress analysis of thin-walled structures to more advanced topics such as the analysis of statically indeterminate structures, warping, constraint stresses, shear diffusion, and elements of plate bending.

Aerodynamics and Aircraft Performance, 3rd edition is a college undergraduate-level introductory textbook on aircraft aerodynamics and performance. This text is designed for a course in Aircraft Performance that is taught before the students have had any course in fluid mechanics, fluid dynamics, or aerodynamics. The text is meant to provide the essential information from these types of courses that is needed for teaching basic subsonic aircraft performance, and it is assumed that the students will learn the full story of aerodynamics in other, later courses. The text assumes that the students will have had a university level Physics sequence in which they will have been introduced to the most fundamental concepts of statics, dynamics, fluid mechanics, and basic conservation laws that are needed to understand the coverage that follows. It is also assumed that students will have completed first year university level calculus sequence plus a course in multi-variable calculus. Separate courses in engineering statics and dynamics are helpful but not necessary. Any student who takes a course using this text after completing courses in aerodynamics or fluid dynamics should find the chapters of this book covering those subjects an interesting review of the material.

The 236-page text was created specifically for use by undergraduate students in Aerospace Engineering and was based on Professor Marchman’s many years of experience teaching related subject matter as well as his numerous wind tunnel research projects related to aircraft aerodynamics and his personal experience as the owner and pilot of a general aviation airplane. It has been used at Virginia Tech and other universities.

Welcome to this course of Aerospace Mechanics of Materials. We are happy that you chose to join us on this exciting journey. This course deals with basic material and geometry dependent analysis of structures. In this course, you will investigate how these material properties, in combination with structural geometries, affect the design and performance of basic structural elements under axial, torsion, bending and shear loading.

We have divided this course into eight different subjects and a review chapter. In those subject, you will find video lectures and readings, where the concepts and theory will be explained; examples, where we will solve a problem for you, so you can reinforce the concepts you have learned; and exercises, that will allow you to test your knowledge.

Aerospace Structures by Eric Raymond Johnson is a 600+ page text and reference book for junior, senior, and graduate-level aerospace engineering students. The text begins with a discussion of the aerodynamic and inertia loads acting on aircraft in symmetric flight and presents a linear theory for the status and dynamic response of thin-walled straight bars with closed and open cross-sections. Isotropic and fiber-reinforced polymer (FRP) composite materials including temperature effects are modeled with Hooke’s law. Methods of analyses are by differential equations, Castigliano’s theorems, the direct stiffness method, the finite element method, and Lagrange’s equations. There are numerous examples for the response axial bars, beams, coplanar trusses, coplanar frames, and coplanar curved bars. Failure initiation by the von Mises yield criterion, buckling, wing divergence, fracture, and by Puck’s criterion for FRP composites are presented in the examples.

This hands-on workshop explores the tool Atelier that was developed to support feedback in programming tutorials. Our teaching philosophy for programming is based on a tinkering approach, that is characterised by playful exploration, driven by curiosity. Students define from the start their own assignments, given only a set of ingredients to use. The role of a teacher is to provide starting points, explain the first steps to take, and to get students unstuck when necessary. This approach puts students in a very active position but is also very feedback intensive.To support giving feedback and to reduce inconsistencies in feedback given by teaching assistants (TAs), we developed a tool, Atelier, that allows to give comments on code and share this with the respective student, and also with TAs and teachers.The hands-on activity will start with an introduction, followed by an online tutorial lecture with some simple programming assignments. Participants will take the role of students as well as TAs and use Atelier to give and receive feedback. After two rounds of programming exercises, we will evaluate the tool with the participants and discuss its use and place in programming education.

This Guide has been developed for facility owner organizations, along with designers, contractors, operators, and consultants who advise owners. We assume that the reader has a fundamental understanding of BIM concepts. For those readers who are not familiar with BIM, it is recommended, that you review BIM literature such as BIG BIM little bim by Jernigan (2008), the BIM Handbook by Eastman et al. (2011), or other BIM resources from the GSA, US Department of Veterans Affairs, US Army Corp of Engineers, and others. This Guide is not intended to convince an organization to use BIM, but rather how to implement it. If the organization has determined that BIM can add value to the organization, this Guide will lead them through the steps to integrate BIM into the organization. However, if the organization is unsure about implementing BIM, it may be necessary to further research the benefits and risks of BIM to make a business case for implementing BIM.

This BIM Project Execution Planning Guide is a product of the BIM Project Execution Planning Project within the buildingSMART alliance™ (bSa), a council within the National Institute of Building Sciences. The bSa is charged with developing the National Building Information Modeling Standard – United States™ (NBIMS-US). This Guide was developed to provide a practical manual that can be used by project teams to design their BIM strategy and develop a BEP. The core modeling and information exchange concepts have been designed to complement the long-term goals of the bSa in the development of a standard that can be implemented throughout the AECOO Industry to improve the efficiency and effectiveness of BIM implementation on projects.

This book treats optics at the level of students in the later stage of their bachelor or the beginning of their master. It is assumed that the student is familiar with Maxwell’s equations. Although the book takes account of the fact that optics is part of electromagnetism, special emphasis is put on the usefulness of approximate models of optics, their hierarchy and limits of validity. Approximate models such as geometrical optics and paraxial geometrical optics are treated extensively and applied to image formation by the human eye, the microscope and the telescope.

This book aims to narrate fundamental concepts of structural design to architecture students such that they have minimum involvement with math problem-solving. Within this book, students learn about different types of loads, forces and vector addition, the concept of equilibrium, internal forces, geometrical and material properties of structural elements, and rules of thumb for estimating the proportion of some structural systems such as catenary cables and arches, trusses, and frame structures.

To safely work with electricity, it is important to have a grasp of the basic theories. Whether we are talking about atomic structure, electrical terms, or measurement devices, understanding the theory of electricity is a key concept. This textbook, divided into three sections, provides easy-to-understand and enjoyable lessons on atomic structure, electrical units, and measurement devices for those training and working as electricians.

This textbook is based on a different paradigm for organizing an engineering science core --- a systems, accounting and modeling approach --- that emphasizes the common, underlying concepts of engineering science. Although this approach is not new, as most graduate students have been struck by this idea sometime during their graduate education, its use as the organizing principle for an undergraduate curriculum is new. By focusing on the underlying concepts and stressing the similarities between subjects that are often perceived by students (and taught by faculty) as unconnected topics, this approach provides engineering students a foundational framework for recognizing and building connections as they travel through their education.

If you’re a coastal engineer, ecologist or planner, then this is the course for you. You already know that engineering and ecological principles are not enough to realize nature-friendly solutions in practice. You need people on your side!

In this course you will learn how to build a relevant coalition of stakeholders to support the design and implementation of ecosystem-based hydraulic infrastructures. After learning basic stakeholder mapping and game theory techniques, you will apply Social Design Principles to a Building with Nature ecosystem-based design case. This will equip you to identify promising collaborative arrangements for your engineering or planning practice.

The course builds on the previous Building with Nature MOOC, which explored the use of natural materials and ecological processes in achieving effective and sustainable hydraulic infrastructure designs, distilling Engineering and Ecological Design Principles. In this course, the missing element of Social Design Principles are developed and taught.

You’ll learn from renowned Dutch engineers and international environmental scientists, who work at the technical- governance interface. Iconic examples such as the Maasvlakte II expansion to Rotterdam Harbor and the Delfland Sand Engine Mega-nourishment serve as study material. The challenges in designing and implementing these nature-friendly hydraulic infrastructures are explored by the eminent professors who were responsible for their genesis.

Join us in becoming one of the new generation of engineers, ecologists and planners who see the Building with Nature integrated design approach as critical to hydraulic engineering, nature and society.

This will be useful in understanding bias compensation and transistor stability i.e. operating point stability.

While big data infiltrates all walks of life, most firms have not changed sufficiently to meet the challenges that come with it. In this course, you will learn how to develop a big data strategy, transform your business model and your organization.

This course will enable professionals to take their organization and their own career to the next level, regardless of their background and position.

Professionals will learn how to be in charge of big data instead of being subject to it. In particular, they will become familiar with tools to:

assess their current situation regarding potential big data-induced changes of a disruptive nature,
identify their options for successfully integrating big data in their strategy, business model and organization, or if not possible, how to exit quickly with as little loss as possible, and
strengthen their own position and that of their organization in our digitalized knowledge economy
The course will build on the concepts of product life cycles, the business model canvas, organizational theory and digitalized management jobs (such as Chief Digital Officer or Chief Informatics Officer) to help you find the best way to deal with and benefit from big data induced changes.

Using natural sensory system concepts to develop and improve sensory systems will continue to thrive for many years to come. Technology advances rapidly (Moore’s Law) as does our understanding of biological principles and designs. These trends fuel the fertile grounds of bio-inspired sensory systems, a topic that is inherently multidisciplinary. This book will serve well as either an academic text on the subject or an introduction to the variety of proven bio-inspired designs. The focus is on sensory systems that interpret environmental stimuli. It introduces natural photo-, mechano-, and chemo-sensory systems across the animal kingdom and also summarizes various novel engineering ideas that glean ideas from these natural sensory systems.

"Build It Yourself: Satellite!" is an online Flash game hosted on the James Webb Space Telescope website. The goal of the game is to explain the decision-making process of satellite design. The user can choose to build a "small," "medium," or "large" astronomy satellite. The user then selects science goals, wavelength, instruments, and optics. The satellite is then launched on the appropriate rocket (shown via an animation). Finally, the user is shown what their satellite might look like, as well as what kind of data it might collect, via examples from similar real-life satellites. Satellites range from small X-ray missions without optics (like the Rossi X-ray Timing Explorer) to large missions with segmented mirrors (like the James Webb Space Telescope).
