Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles - Board On Energy And Environmental Systems - Bog -

Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles - Board On Energy And Environmental Systems - Bog -

Medium- and heavy-duty trucks, motor coaches, and transit buses - collectively, "medium- and heavy-duty vehicles", or MHDVs - are used in every sector of the economy. The fuel consumption and greenhouse gas emissions of MHDVs have become a focus of legislative and regulatory action in the past few years. Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two is a follow-on to the National Research Council's 2010 report, Technologies and Approaches to Reducing the Fuel Consumption of Medium-and Heavy-Duty Vehicles. That report provided a series of findings and recommendations on the development of regulations for reducing fuel consumption of MHDVs. This report comprises the first periodic, five-year follow-on to the 2010 report. Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two reviews NHTSA fuel consumption regulations and considers the technological, market and regulatory factors that may be of relevance to a revised and updated regulatory regime taking effect for model years 2019-2022. The report analyzes and provides options for improvements to the certification and compliance procedures for medium- and heavy-duty vehicles; reviews an updated analysis of the makeup and characterization of the medium- and heavy-duty truck fleet; examines the barriers to and the potential applications of natural gas in class 2b through class 8 vehicles; and addresses uncertainties and performs sensitivity analyses for the fuel consumption and cost/benefit estimates.

Reducing Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two - Board On Energy And Environmental Systems - Bog

Medium- and heavy-duty trucks, motor coaches, and transit buses - collectively, "medium- and heavy-duty vehicles", or MHDVs - are used in every sector of the economy. The fuel consumption and greenhouse gas emissions of MHDVs have become a focus of legislative and regulatory action in the past few years. This study is a follow-on to the National Research Council's 2010 report, Technologies and Approaches to Reducing the Fuel Consumption of Medium-and Heavy-Duty Vehicles. That report provided a series of findings and recommendations on the development of regulations for reducing fuel consumption of MHDVs. On September 15, 2011, NHTSA and EPA finalized joint Phase I rules to establish a comprehensive Heavy-Duty National Program to reduce greenhouse gas emissions and fuel consumption for on-road medium- and heavy-duty vehicles. As NHTSA and EPA began working on a second round of standards, the National Academies issued another report, Reducing the Fuel Consumption and Greenhouse Gas Emissions of Medium- and Heavy-Duty Vehicles, Phase Two: First Report, providing recommendations for the Phase II standards. This third and final report focuses on a possible third phase of regulations to be promulgated by these agencies in the next decade.

Mastering Ruby on Rails - - Bog - Taylor & Francis Ltd - Plusbog.dk

There is no shortage of programming languages and frameworks out there. But in the midst of all this, Ruby on Rails stands out. Despite losing out on the top spot to other contenders, Ruby on Rails has earned for itself a position of repute and a robust user base. Ever since its debut in 2004, Ruby on Rails has rapidly become one of the most impactful and popular tools for building dynamic web applications. Rails owes much of its success to its compact design and the usage of the underlying Ruby language. It effectively creates a domain-specific language for writing web applications. As a result, many common web programming tasks—such as generating HTML, making data models, and routing URLs—are easier with Rails. Although its outstanding capabilities have made Ruby on Rails one of the world’s most popular web development frameworks, some might still find it challenging to learn and use. Mastering Ruby on Rails: A Beginner’s Guide could be just the right solution for that. Whatever your previous web development experience is, Mastering Ruby on Rails can guide you to true Rails proficiency. It will help you to: - - Install and set up your Rails development environment - - - Go beyond generated code to build Rails applications from scratch - - - Effectively use the Model-View-Controller (MVC) pattern - - - Master the Ruby programming skills all Rails developers need - - - Define high-quality site layouts and data models - - - Add social features and navigate Asynchronous Javascript and XML (Ajax) - Mastering Ruby on Rails will walk you through Rails'' inner workings and equip you to tackle complicated projects with solutions that are well-tested, adaptive, and easy to maintain. This book starts by explaining critical points behind object-oriented programming and builds toward creating a full Rails application within a few chapters. By the end of this book, besides in-depth knowledge of Rails, you will also have a basic understanding of many supporting technologies such as SQL, web frameworks, and Integrated Development Environment (IDE). You will be able to quickly grasp the Rails methodology by focusing on the development from the point of view of the beginner-level developer. Additionally, you will be provided with a reliable roadmap for migrating your applications, skill set, and development procedures to the newer, more flexible programming platform that Rails offers. Moreover, learning Rails development independently will let you use all the qualities like creativeness, critical thinking, and project management. Mastering Ruby on Rails serves as a complete guide to exploring Ruby on Rails, expanding your set of skills and experience that will only benefit you throughout your professional life. If you are looking to get into the fascinating world of Rails development, Mastering Ruby on Rails is the right pick for you!

Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles - National Research Council - Bog - National Academies

Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles - National Research Council - Bog - National Academies

Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S. The miles-per-gallon measure used to regulate the fuel economy of passenger cars. is not appropriate for medium- and heavy-duty vehicles, which are designed above all to carry loads efficiently. Instead, any regulation of medium- and heavy-duty vehicles should use a metric that reflects the efficiency with which a vehicle moves goods or passengers, such as gallons per ton-mile, a unit that reflects the amount of fuel a vehicle would use to carry a ton of goods one mile. This is called load-specific fuel consumption (LSFC). The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.

Heavy Duty - K. K. Downing - Bog - Little, Brown Book Group - Plusbog.dk

Heavy Duty - K. K. Downing - Bog - Little, Brown Book Group - Plusbog.dk

''A must for fans and rock buffs'' The Sun ''Fascinating read'' Powerplay Judas Priest formed in Birmingham in 1969. With its distinctive twin-guitar sound, studs-and-leather image, and international sales of over 50 million records, Judas Priest became the archetypal heavy metal band in the 1980s. Iconic tracks like ''Breaking the Law'', ''Living after Midnight'', and ''You''ve Got Another Thing Coming'' helped the band achieve extraordinary success, but no one from the band has stepped out to tell their or the band''s story until now.As the band approaches its golden anniversary, fans will at last be able to delve backstage into the decades of shocking, hilarious, and haunting stories that surround the heavy metal institution. In Heavy Duty , guitarist K.K. Downing discusses the complex personality conflicts, the business screw-ups, the acrimonious relationship with fellow heavy metal band Iron Maiden, as well as how Judas Priest found itself at the epicentre of a storm of parental outrage that targeted heavy metal in the ''80s. He also describes his role in cementing the band''s trademark black leather and studs image that would not only become synonymous with the entire genre, but would also give singer Rob Halford a viable outlet by which to express his sexuality. Lastly, he recounts the life-changing moment when he looked at his bandmates on stage during a 2009 concert and thought, ''This is the last show''. Whatever the topic, whoever''s involved, K.K. doesn''t hold back.From the band at the very beginning until his retirement in 2011 (and even still as a member of the band''s board of directors), Downing has seen it all and is now finally at a place in his life where he can also let it all go. Even if you''re a lifelong fan, if you think you know the full story of Judas Priest, well, you''ve got another thing coming.
