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.

Component-Based Rails Applications - Stephan Hagemann - Bog - Pearson Education (US) - Plusbog.dk

Use Components to Improve Maintainability, Reduce Complexity, and Accelerate Testing in Large Rails Applications “This book gives Ruby pros a comprehensive guide for increasing the sophistication of their designs, without having to forsake the principles of elegance that keep them in our corner of the software world.” –Obie Fernandez, author, The RailsTM 5 Way, Fourth Edition As Rails applications grow, even experienced developers find it difficult to navigate code bases, implement new features, and keep tests fast. Components are the solution, and Component-Based Rails Applications shows how to make the most of them. Writing for programmers and software team leads who are comfortable with Ruby and Rails, Stephan Hagemann introduces a practical, start-to-finish methodology for modernizing and restructuring existing Rails applications. One step at a time, Hagemann demonstrates how to revamp Rails applications to exhibit visible, provably independent, and explicitly connected parts–thereby simplifying them and making them far easier for teams to manage, change, and test. Throughout, he introduces design concepts and techniques you can use to improve applications of many kinds, even if they weren’t built with Rails or Ruby. - - Learn how components clarify intent, improve collaboration, and simplify innovation and maintenance - - Create a full Rails application within a component, from first steps to migrations and dependency management - - Test component-based applications, manage assets and dependencies, and deploy your application to production - - Identify the seams in an existing Rails application, and refactor it to extract components - - Master a scripted, repeatable approach for refactoring Rails applications of any size - - Use component-based Rails with two popular structural patterns: hexagonal and DCI architecture - - Leverage your new component skills with other frameworks and languages - - Overcome the unique challenges that arise as you componentize Rails applications - If you’re ready to simplify and revitalize your complex Rails systems, you’re ready for Component-Based Rails Applications .
