Download or read book Cost Effectiveness and Deployment of Fuel Economy Technologies for Light Duty Vehicles written by National Research Council and published by National Academies Press. This book was released on 2015-09-28 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: The light-duty vehicle fleet is expected to undergo substantial technological changes over the next several decades. New powertrain designs, alternative fuels, advanced materials and significant changes to the vehicle body are being driven by increasingly stringent fuel economy and greenhouse gas emission standards. By the end of the next decade, cars and light-duty trucks will be more fuel efficient, weigh less, emit less air pollutants, have more safety features, and will be more expensive to purchase relative to current vehicles. Though the gasoline-powered spark ignition engine will continue to be the dominant powertrain configuration even through 2030, such vehicles will be equipped with advanced technologies, materials, electronics and controls, and aerodynamics. And by 2030, the deployment of alternative methods to propel and fuel vehicles and alternative modes of transportation, including autonomous vehicles, will be well underway. What are these new technologies - how will they work, and will some technologies be more effective than others? Written to inform The United States Department of Transportation's National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) emission standards, this new report from the National Research Council is a technical evaluation of costs, benefits, and implementation issues of fuel reduction technologies for next-generation light-duty vehicles. Cost, Effectiveness, and Deployment of Fuel Economy Technologies for Light-Duty Vehicles estimates the cost, potential efficiency improvements, and barriers to commercial deployment of technologies that might be employed from 2020 to 2030. This report describes these promising technologies and makes recommendations for their inclusion on the list of technologies applicable for the 2017-2025 CAFE standards.

Book excerpt: "Body Physics was designed to meet the objectives of a one-term high school or freshman level course in physical science, typically designed to provide non-science majors and undeclared students with exposure to the most basic principles in physics while fulfilling a science-with-lab core requirement. The content level is aimed at students taking their first college science course, whether or not they are planning to major in science. However, with minor supplementation by other resources, such as OpenStax College Physics, this textbook could easily be used as the primary resource in 200-level introductory courses. Chapters that may be more appropriate for physics courses than for general science courses are noted with an asterisk symbol (*). Of course this textbook could be used to supplement other primary resources in any physics course covering mechanics and thermodynamics"--Textbook Web page.
Download or read book EdJourney written by Grant Lichtman and published by John Wiley & Sons. This book was released on 2014-09-09 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Your formula for managing innovation and transforming learning #EdJourney: A Roadmap to the Future of Education is a refreshing change from the negativity so common in the world of education today. Over the course of a 3-month solo road trip across the United States, author Grant Lichtman discovered that there is much to be positive about in today's K-12 schools. Lichtman, one of the country's leading experts in educational innovation, interviewed over 600 teachers, administrators, students, parents, and trustees to find out what kind of innovations they're doing right—and how others can leverage their successes. Innovation in education takes hard work, planning, and cooperation. With examples from around the country and findings from the latest education research, #EdJourney maps out how administrators and teachers can embrace the innovation process that schools and learners need now. Today's 21st century education presents unique challenges and opportunities to students, and this is a trailblazing practical guide to making sure education is ready for the future. #EdJourney focuses on four key questions: What new learning strategies are the top schools implementing to prepare our students for their future rather than for our past? How do teachers and administrators manage transitions to new types of teaching and learning? What are the key obstacles to shifting away from the assembly line model of education? How can we all leverage the lessons of success from the most innovative schools? The concrete examples and advice in this book will help you bring innovation and educational design concepts into your school. #EdJourney goes beyond the theoretical need for change—by now a familiar topic to almost everyone—and takes a real-world approach to achieving transformative education in any school.
Download or read book The Convenience Revolution written by Shep Hyken and published by Sound Wisdom. This book was released on 2018-10-02 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: Convenience is King When you make it easier for customers to do business with you, they will reward you with their money, their loyalty, and their referrals. There’s a reason they call it a convenience store – because it’s convenient! When you have to pick up a gallon of milk, would you rather stop by a large supermarket or a 7-Eleven? Customers who shop at convenience stores know the selection is smaller and the prices are often higher...yet they still come in droves because of the ease of purchase. What about the minibar in your hotel room? That’s convenient too...but the convenience comes at a cost. Did you ever stop to think that the same $5.00 can of Coca-Cola in the hotel’s mini-fridge can be bought down the hall from the vending machine for just $1.25? Yet even with that can of Coke being four times more expensive, hotels are restocking minibars every day. Customers will pay for convenience. And they’ll choose to do more business over time with the people and companies that make their lives more convenient! Whether you’re trying to out-service a competitor or disrupt an entire industry, creating less friction and being more convenient for your customers should be your strategy. When you raise the convenience bar, you create the next level of amazing customer experience. This book shows you how to leverage convenience as a powerful way to differentiate yourself from your competition. You’ll learn six compelling strategies, supported by numerous examples and case studies that will fuel your plan to create a focus on convenience for your customers. The value proposition is both simple and profound: when you reduce friction and make it easier for customers to do business with you, they’ll reward you with their money, their loyalty, and their referrals. That’s the advantage of being a part of The Convenience Revolution.
Download or read book Method of Dimensionality Reduction in Contact Mechanics and Friction written by Valentin L. Popov and published by Springer. This book was released on 2014-08-19 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes for the first time a simulation method for the fast calculation of contact properties and friction between rough surfaces in a complete form. In contrast to existing simulation methods, the method of dimensionality reduction (MDR) is based on the exact mapping of various types of three-dimensional contact problems onto contacts of one-dimensional foundations. Within the confines of MDR, not only are three dimensional systems reduced to one-dimensional, but also the resulting degrees of freedom are independent from another. Therefore, MDR results in an enormous reduction of the development time for the numerical implementation of contact problems as well as the direct computation time and can ultimately assume a similar role in tribology as FEM has in structure mechanics or CFD methods, in hydrodynamics. Furthermore, it substantially simplifies analytical calculation and presents a sort of “pocket book edition” of the entirety contact mechanics. Measurements of the rheology of bodies in contact as well as their surface topography and adhesive properties are the inputs of the calculations. In particular, it is possible to capture the entire dynamics of a system – beginning with the macroscopic, dynamic contact calculation all the way down to the influence of roughness – in a single numerical simulation model. Accordingly, MDR allows for the unification of the methods of solving contact problems on different scales. The goals of this book are on the one hand, to prove the applicability and reliability of the method and on the other hand, to explain its extremely simple application to those interested.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Friction and Its Reduction They have been revised and considerable new matter added. The writer had often felt the want of some small and concise resume of the many records of experi ments on Friction scattered throughout the proceedings of the various scientific institutions, and also of some outline of the various kinds of lubricants and their properties, with the usual methods of testing them. It is hoped the work will be found useful not only to those actually engaged upon the design of machinery, but also to students and those many users of oils who could not rank themselves as technical men. For the conveni ence of all, the writer has ventured to depart from the somewhat beaten track in giving a few prices of various oils, and also balls and ball bearings. He has often felt hampered, when Wishing to know the comparative cost of various methods, to find all such information sedulously excluded from Engineering literature.

Download or read book Friction Reduction by Algal and Bacterial Polymers written by Paul R. Kenis and published by . This book was released on 1971 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Long-chain polymers from many seaweeds, microscopic algae, and bacteria have been demonstrated to reduce turbulent-flow friction in water. In the investigation all water samples tested from inland and marine sources gained friction-reduction ability when enriched with sugar, as a consequence of polysaccharide synthesis by bacteria. Biological polymers, therefore, are the probable cause of the unexplainable variations in hydrodynamic test facilities. Bacterial polysaccharides were more effective than seaweed extracts at low concentrations for friction reduction, but both were much less effective than synthetic polymers. Turbulent-flow frictional measurements were found to be sensitive for the detection, measurement, and partial characterization of long-chain polymers. (Author).
