| diagram of a bathtub: Digital Transmission Dayan Adionel Guimaraes, 2010-01-18 Digital Transmission – A Simulation-Aided Introduction with VisSim/Comm is a book in which basic principles of digital communication, mainly pertaining to the physical layer, are emphasized. Nevertheless, these principles can serve as the fundamentals that will help the reader to understand more advanced topics and the associated technology. In this book, each topic is addressed in two different and complementary ways: theoretically and by simulation. The theoretical approach encompasses common subjects covering principles of digital transmission, like notions of probability and stochastic processes, signals and systems, baseband and passband signaling, signal-space representation, spread spectrum, multi-carrier and ultra wideband transmission, carrier and symbol-timing recovery, information theory and error-correcting codes. The simulation approach revisits the same subjects, focusing on the capabilities of the communication system simulation software VisSim/Comm on helping the reader to fulfill the gap between the theory and its practical meaning. The presentation of the theory is made easier with the help of 357 illustrations. A total of 101 simulation files supplied in the accompanying CD support the simulation-oriented approach. A full evaluation version and a viewer-only version of VisSim/Comm are also supplied in the CD. |

| diagram of a bathtub: Biology Made Real Christian Moore-Anderson, 2023-04-05 'This outstanding book... deserves to be very widely read. I hope it makes a major contribution to how school biology is taught.' —Dr Michael J. Reiss, Professor of Science Education, University of London 'This is a book that all teachers, not just biology teachers should read.' —Ben Strathearn-Burrows, Head of Biology, Emanuel School What you'll find inside: —A vision for an integrated and meaningful biology education. —A framework for teaching for meaning-making, which cuts planning time. —Ways of creating a unified narrative across disparate topics. —A taxonomy of understanding that unlocks problem-solving with minimal workload. —Tried and tested examples from mixed-attainment biology classrooms. Introduction I've been motivated to discover what biology is to us as humans. What it means to understand biology, and how I could make it meaningful for my students. I've read as much as I could and reflected, I've discussed and listened, I've taught and observed. While it doesn't cover all aspects of biology education, this book is about sharing what I've learnt on my journey of synthesising and trialling ideas with my secondary-school mixed-attainment biology classes. 'Not only is this book likely to change how you teach biology but also how you perceive yourself within the living world.' —Dr Alex Sinclair, Institute of Education, St Mary's University, Twickenham Chapter 1: Meaningful biology relates principally to organisms: This sets the scene for the whole book. It brings together many threads to define what I see as most meaningful to secondary biology students. And therefore what we could do about it when designing our lessons & curricula and thinking about how students progress through their biology education. Planning for meaning-making has vastly enhanced interest and motivation to learn in my classroom. Chapters 2 & 3: Teaching for meaning using variation theory: Next I introduce a powerful—relatively unknown and often misunderstood—pedagogical theory. Variation theory. In these chapters I set out to show how useful it is—and easy to use—in the secondary biology classroom, with many examples. Chapter 4: How to integrate organisms, ecology & evolution: Now I pull together the previous chapters to present a new framework for teaching for meaning-making that cuts planning time & focuses on biology. 'An excellent text demanding we think not just about what we teach but also why and how.’ —Dr Paul Ganderton, Consultant and researcher Chapter 5: Concepts of the organism that unite a biology course: Here I discuss two concepts that I think can unify all the topics on the curriculum. 1. Seeing biology through thermodynamic systems lens and, 2. Seeing biology through an ecological-evolutionary lens via the concept of life strategies. I lay out the reasons why and discuss how I've introduced these ideas with students. Chapter 6: Teaching systems thinking to help students see interconnectedness: This chapter is dedicated to systems thinking. Firstly I show how stock and flow diagrams are very useful for the biology classroom and give examples. Next, I introduce a new taxonomy of understanding biological systems. Chapter 7: Establishing a thinking classroom: This chapter is focused on the whys and hows of embedding the taxonomy into my biology curricula. I give examples of how I use it and examples of my students answers from lower and upper secondary courses. Chapter 8: Navigating classroom and biological complexity: This chapter rounds up the book by considering the complexity of our subject and the classroom. ‘Biology Made Real comes with an education health warning—be prepared to have your beliefs challenged.' —Dr Alex Sinclair |

| diagram of a bathtub: Blueprint Reading And Sketching Including Machine Drawings; Piping Systems; Electrical and Electronics Prints; Architectural and Structural Steel Drawings , Chapter 1 BLUEPRINTS When you have read and understood this chapter, you should be able to answer the following learning objectives: Describe blueprints and how they are produced. Identify the information contained in blueprints. Explain the proper filing of blueprints. Blueprints (prints) are copies of mechanical or other types of technical drawings. The term blueprint reading, means interpreting ideas expressed by others on drawings, whether or not the drawings are actually blueprints. Drawing or sketching is the universal language used by engineers, technicians, and skilled craftsmen. Drawings need to convey all the necessary information to the person who will make or assemble the object in the drawing. Blueprints show the construction details of parts, machines, ships, aircraft, buildings, bridges, roads, and so forth. BLUEPRINT PRODUCTION Original drawings are drawn, or traced, directly on translucent tracing paper or cloth, using black waterproof India ink, a pencil, or computer aided drafting (CAD) systems. The original drawing is a tracing or “master copy.” These copies are rarely, if ever, sent to a shop or site. Instead, copies of the tracings are given to persons or offices where needed. Tracings that are properly handled and stored will last indefinitely. The term blueprint is used loosely to describe copies of original drawings or tracings. One of the first processes developed to duplicate tracings produced white lines on a blue background; hence the term blueprint. Today, however, other methods produce prints of different colors. The colors may be brown, black, gray, or maroon. The differences are in the types of paper and developing processes used. A patented paper identified as BW paper produces prints with black lines on a white background. The diazo, or ammonia process, produces prints with either black, blue, or maroon lines on a white background. Another type of duplicating process rarely used to reproduce working drawings is the photostatic process in which a large camera reduces or enlarges a tracing or drawing. The photostat has white lines on a dark background. Businesses use this process to incorporate reduced-size drawings into reports or records. The standards and procedures prescribed for military drawings and blueprints are stated in military standards (MIL-STD) and American National Standards Institute (ANSI) standards. The Department of Defense Index of Specifications and Standards lists these standards; it is issued on 31 July of each year. The following list contains common MIL-STD and ANSI standards, listed by number and title, that concern engineering drawings and blueprints. |

| diagram of a bathtub: Micro, Meso, Macro Hans Liljenstrm, Uno Svedin, 2005 In the domain of science concerned with systems structure and behavior, the issue of the relationship between the micro and the macro level is of key importance. This book concentrates on the interplay between these levels and has a special focus on the level OC in betweenOCO OCo the meso level. An investigation of those links is made through a number of cases from different domains of science, including physics, chemistry, ecology, social science, economics and technology. What is evident is that there are facets regarding meso-level issues that are similar between cases, but also that the domains differ in various ways. This is particularly exemplified by the differences in perspectives from which the natural and social sciences deal with scaling issues. The various examples provided in this book mirror its overriding theme: systems complexity. |

| diagram of a bathtub: Next Generation HALT and HASS Kirk A. Gray, John J. Paschkewitz, 2016-03-11 Next Generation HALT and HASS presents a major paradigm shift from reliability prediction-based methods to discovery of electronic systems reliability risks. This is achieved by integrating highly accelerated life test (HALT) and highly accelerated stress screen (HASS) into a physics-of-failure-based robust product and process development methodology. The new methodologies challenge misleading and sometimes costly mis-application of probabilistic failure prediction methods (FPM) and provide a new deterministic map for reliability development. The authors clearly explain the new approach with a logical progression of problem statement and solutions. The book helps engineers employ HALT and HASS by illustrating why the misleading assumptions used for FPM are invalid. Next, the application of HALT and HASS empirical discovery methods to quickly find unreliable elements in electronics systems gives readers practical insight to the techniques. The physics of HALT and HASS methodologies are highlighted, illustrating how they uncover and isolate software failures due to hardware-software interactions in digital systems. The use of empirical operational stress limits for the development of future tools and reliability discriminators is described. Key features: * Provides a clear basis for moving from statistical reliability prediction models to practical methods of insuring and improving reliability. * Challenges existing failure prediction methodologies by highlighting their limitations using real field data. * Explains a practical approach to why and how HALT and HASS are applied to electronics and electromechanical systems. * Presents opportunities to develop reliability test discriminators for prognostics using empirical stress limits. * Guides engineers and managers on the benefits of the deterministic and more efficient methods of HALT and HASS. * Integrates the empirical limit discovery methods of HALT and HASS into a physics of failure based robust product and process development process. |

| diagram of a bathtub: Monolithically Integrated Transceiver Chips for Bidirectional Optical Data Transmission Alexander Kern, 2016-02-03 Vertical-cavity surface-emitting lasers (VCSELs) emitting at 850 nm wavelength are known for their attractive optical features and a continuously growing range of applications. The main goal of the present thesis is to demonstrate the feasibility of a monolithical integration of VCSELs with PIN-type photodiodes (PDs) for the operation as transceiver (TRx) chips in optical data links. The project milestones comprise the chip and the epitaxial layer design of the VCSEL–PIN PD device based on a traditional AlGaAs/GaAs material system, its fabrication development, electro-optical characterizations, and data transmission in a bidirectional optical link over a single, two-side butt-coupled standard graded-index (GI) multimode fiber (MMF). The monolithic design lowers the costs in the semiconductor technology as well as in packaging and additionally avoids the use of external optics, even though it is employed with a single 50 μm core diameter GI MMF. Thus, the very compact optical link saves space, weight, and module cost. Deep insights into the electro-optical properties of VCSELs and PIN PDs are given by the theoretical description and measurements. The limitations of small-signal modulation responses are of main interest of this thesis. Thus, the dynamic characteristics including the extraction of modeled parasitics are presented. Also the electrical and optical crosstalk between the integrated devices and both transmission channels as well as the fiber alignment tolerances are covered. The results in optical data transmission consisting of various experiments in half-duplex and full-duplex mode, both free-space and fiber-coupled over a single MMF are comprised. The monolithic TRx design is well suited for low-cost, compact optical links over distances of a few hundred meters. Capable to handle data rates of up to 10 Gbit/s and more, these TRx chips can be employed, e.g., to upgrade existing standard MMF networks to bidirectional operation or in mobile, low-cost, automotive networks. |

| diagram of a bathtub: Process for System Architecture and Requirements Engineering Derek Hatley, Peter Hruschka, Imtiaz Pirbhai, 2013-08-02 This is the digital version of the printed book (Copyright © 2000). Derek Hatley and Imtiaz Pirbhai—authors of Strategies for Real-Time System Specification—join with influential consultant Peter Hruschka to present a much anticipated update to their widely implemented Hatley/Pirbhai methods. Process for System Architecture and Requirements Engineering introduces a new approach that is particularly useful for multidisciplinary system development: It applies equally well to all technologies and thereby provides a common language for developers in widely differing disciplines. The Hatley-Pirbhai-Hruschka approach (H/H/P) has another important feature: the coexistence of the requirements and architecture methods and of the corresponding models they produce. These two models are kept separate, but the approach fully records their ongoing and changing interrelationships. This feature is missing from virtually all other system and software development methods and from CASE tools that only automate the requirements model. System managers, system architects, system engineers, and managers and engineers in all of the diverse engineering technologies will benefit from this comprehensive, pragmatic text. In addition to its models of requirements and architecture and of the development process itself, the book uses in-depth case studies of a hospital monitoring system and of a multidisciplinary groundwater analysis system to illustrate the principles. Compatibility Between the H/H/P Methods and the UML: The Hatley/Pirbhai architecture and requirements methods—described in Strategies for Real-Time System Specification—have been widely used for almost two decades in system and software development. Now known as the Hatley/Hruschka/Pirbhai (H/H/P) methods, they have always been compatible with object-oriented software techniques, such as the UML, by defining architectural elements as classes, objects, messages, inheritance relationships, and so on. In Process for System Architecture and Requirements Engineering, that compatibility is made more specific through the addition of message diagrams, inheritance diagrams, and new notations that go with them. In addition, state charts, while never excluded, are now specifically included as a representation of sequential machines. These additions make definition of the system/software boundary even more straightforward, while retaining the clear separation of requirements and design at the system levels that is a hallmark of the H/H/P methods—not shared by most OO techniques. Once the transition to software is made, the developer is free to continue using the H/H/P methods, or to use the UML or any other software-specific technique. |
| diagram of a bathtub: System Zoo 1 Simulation Models Hartmut Bossel, 2007 About the book: Mathematical modeling and computer simulation make it possible to understand and control the dynamic processes taking place in complex systems. Simulation provides insights into the often surprising diversity of possible behaviors, and allows identifying possibilities for intervention and options for alternative development. About one hundred simulation models from all areas of life are fully documented in the three volumes of the 'System Zoo'. They can be quickly implemented and easily operated using freely available system dynamics software. Volume 1 of the System Zoo contains simulation models of elementary processes, and of complex systems from physics and engineering, among them: exponential and logistic growth, oscillations, delays, and storage; phenomena of infection, transition, and overload; complex systems with limit cycles, multiple equilibrium points and chaotic attractors; and applications from control engineering, flight dynamics, fluid flow and heat conduction. The System Zoo collection of simulation models is particularly well-suited for teaching, training, and research projects at all levels from high school to university, and for individual study. Volume 2 of the System Zoo contains simulation models related to climate, vegetation, ecosystems and resources. Volume 3 deals with systems and processes found in economy and society, and with long-term global development. About the author: Hartmut Bossel is Professor Emeritus of environmental systems analysis. He taught for many years at the University of California in Santa Barbara and the University of Kassel, Germany, where he was director of the Center for Environmental Systems Research until his retirement. He holds an engineering degree from the Technical University of Darmstadt, and a Ph.D. degree from the University of California at Berkeley. With a background in engineering, systems science, and mathematical modeling, he has led many research projects and future studies in different countries, developing computer simulation models and decision support systems in the areas of energy supply policy, global dynamics, orientation of behavior, agricultural policy, and forest dynamics and management. He has written numerous books on modeling and simulation of dynamic systems, social change and future paths, and has published widely in the scientific literature in several fields. |

| diagram of a bathtub: Dynamic Models in Biology Stephen P. Ellner, John Guckenheimer, 2011-09-19 From controlling disease outbreaks to predicting heart attacks, dynamic models are increasingly crucial for understanding biological processes. Many universities are starting undergraduate programs in computational biology to introduce students to this rapidly growing field. In Dynamic Models in Biology, the first text on dynamic models specifically written for undergraduate students in the biological sciences, ecologist Stephen Ellner and mathematician John Guckenheimer teach students how to understand, build, and use dynamic models in biology. Developed from a course taught by Ellner and Guckenheimer at Cornell University, the book is organized around biological applications, with mathematics and computing developed through case studies at the molecular, cellular, and population levels. The authors cover both simple analytic models--the sort usually found in mathematical biology texts--and the complex computational models now used by both biologists and mathematicians. Linked to a Web site with computer-lab materials and exercises, Dynamic Models in Biology is a major new introduction to dynamic models for students in the biological sciences, mathematics, and engineering. |
| diagram of a bathtub: Systems Thinking For Social Change David Peter Stroh, 2015-09-24 David Stroh has produced an elegant and cogent guide to what works. Research with early learners is showing that children are natural systems thinkers. This book will help to resuscitate these intuitive capabilities and strengthen them in the fire of facing our toughest problems.—Peter Senge, author of The Fifth Discipline Concrete guidance on how to incorporate systems thinking in problem solving, decision making, and strategic planning—for everyone! Donors, leaders of nonprofits, and public policy makers usually have the best of intentions to serve society and improve social conditions. But often their solutions fall far short of what they want to accomplish and what is truly needed. Moreover, the answers they propose and fund often produce the opposite of what they want over time. We end up with temporary shelters that increase homelessness, drug busts that increase drug-related crime, or food aid that increases starvation. How do these unintended consequences come about and how can we avoid them? By applying conventional thinking to complex social problems, we often perpetuate the very problems we try so hard to solve, but it is possible to think differently, and get different results. Systems Thinking for Social Change enables readers to contribute more effectively to society by helping them understand what systems thinking is and why it is so important in their work. It also gives concrete guidance on how to incorporate systems thinking in problem solving, decision making, and strategic planning without becoming a technical expert. Systems thinking leader David Stroh walks readers through techniques he has used to help people improve their efforts on complex problems like: ending homelessness improving public health strengthening education designing a system for early childhood development protecting child welfare developing rural economies facilitating the reentry of formerly incarcerated people into society resolving identity-based conflicts and more! The result is a highly readable, effective guide to understanding systems and using that knowledge to get the results you want. |

The International Civil Aviation Organization (ICAO) has mandated that all of its member states implement Safety Management System (SMS) programs in their aviation industries. While some countries (Australia, Canada, members of the European Union, New Zealand) have been engaged in SMS for a few years, it's just now emerging in the United States, and is non-existent in most other countries. This timely and unique book covers the essential points of SMS. The knowledgeable authors go beyond merely defining it; they discuss the quality management underpinnings of SMS, the four pillars, risk management, reliability engineering, SMS implementation, and the scientific rigor that must be designed into proactive safety. This comprehensive work is designed as a textbook for the student of aviation safety, and is an invaluable reference tool for the SMS practitioner in any segment of aviation. The authors introduce a hypothetical airline-oriented safety scenario at the beginning of the book and conclude it at the end, engaging the reader and adding interest to the text. To enhance the practical application of the material, the book also features numerous SMS in Practice commentaries by some of the most respected names in aviation safety. |
| diagram of a bathtub: Hydropower Economics Finn R. Førsund, 2015-01-27 This is a thorough revision of the 2007 publication, and includes five new chapters and brings all existing chapters completely up to date. There have been many advances in hydropower and renewable technologies since the original publication, and Europe, and particularly Scandinavia, plan many more in the coming years. From a review of the original edition: “... it is important to note that the author deals well with his selected topics. ... I recommend this book to all readers who wish to learn more about the economics of hydroelectric power. (Amitrajeet A. Batabyal, Interfaces, Vol. 39 (1), January-February, 2009) |
| diagram of a bathtub: Hydropower Economics Finn R. Forsund, 2007-09-19 There are few more urgent topics in today’s world, so full of ecological uncertainty. Hydropower Economics uses various econometric measures to examine sustainable alternative energy sources. It kicks off by modeling hydropower, yes, but it does not end there. Forsund has extended his model to include thermal power and wind power, too – forms of alternative energy that are taking on an ever larger profile. |
