MicroStation PowerDraft is a professional-level application used for production 2D/3D drafting and detailing. PowerDraft provides an intuitive interface for creating, editing, and manipulating drawings and models in DGN or DWG format and is completely integrated with all Bentley solutions.
Because PowerDraft and MicroStation are based on the same code base, they share many of the same features and functions, including MicroStation's full suite of referencing, dimensioning, text, and drawing tools.
PowerDraft maximizes your production drafting functionality:
Data Interoperability - Native support for DGN and DWG files allows you to focus on creating and using your design data rather than on deliverable file formats, data exchange, and file translations.
Change Management - Track the evolution of each DGN file using PowerDraft's robust design history capability. Combined with digital rights and digital signatures, you can monitor progress and add security and accountability to your projects.
Workflow Support - PowerDraft integrates seamlessly with your organizational processes and is the perfect complement to existing MicroStation workflows.
Extensibility - Flexible programming support makes PowerDraft highly adaptable to your business needs and requirements.

Traffic crashes have become the epidemic of the third millennium a seemingly necessary evil that accompanies increasing levels of motorization. In this comprehensive book, Dr David Shinar provides a theoretical framework and a critical evaluation of the most recent research findings to comprehend the complexity of traffic safety and the central role that drivers, motorcyclists, and pedestrians play in it. In approximately 800 pages with over 250 graphs and tables, Shinar covers the key issues that relate human behavior to traffic safety.

Author: ROBERT D. ZUCKER & OSCAR BIBLARZ | Size: 4.25 MB | Format:PDF | Quality:Original preprint | Publisher: JOHN WILEY & SONS, INC. | Year: 1988 | pages: 500 | ISBN: 0-471-05967-6
Preface :
This book is written for the average student who wants to learn the fundamentals of gas dynamics. It aims at the undergraduate level and thus requires a minimum of prerequisites. The writing style is informal and incorporates ideas in educational technology such as behavioral objectives, meaningful summaries, and check tests. Such features make this book well suited for self-study as well as for conventional course presentation. Sufficient material is included for a typical one-quarter or onesemester course, depending on the student’s background.
Our approach in this book is to develop all basic relations on a rigorous basis with equations that are valid for the most general case of the unsteady, three-dimensional flow of an arbitrary fluid. These relations are then simplified to represent meaningful engineering problems for one- and two-dimensional steady flows. All basic internal and external flows are covered with practical applications which are interwoven throughout the text. Attention is focused on the assumptions made at every step of the analysis; emphasis is placed on the usefulness of the T –s diagram and the significance of any relevant loss terms.
Examples and problems are provided in both the English Engineering and SI systems of units. Homework problems range from the routine to the complex, with all charts and tables necessary for their solution included in the Appendixes. The goals for the user should be not only to master the fundamental concepts but also to develop good problem-solving skills. After completing this book the student should be capable of pursuing the many references that are available on more advanced topics.
Professor Oscar Biblarz joins Robert D. Zucker as coauthor in this edition. We have both taught gas dynamics from this book for many years. We both shared in the preparation of the new manuscript and in the proofreading. This edition has been expanded to include (1) material on conical shocks, (2) several sections showing how computer calculations can be helpful, and (3) an entire chapter on real gases, including simple methods to handle these problems. These topics have made the book more complete while retaining its original purpose and style.

This report discusses the concept, analysis and design procedures, design alternatives and fabrication techniques recommended for precast prestressed horizontally curved bridge beams. Comparisons of curved precast bridge superstructures with steel and cast-in-place concrete demonstrate the aesthetic and economic advantages a precast concrete solution offers to bridge owners and engineers. Three separate appendixes contain plans and details, design charts and a design example applying the design
aids.
