Verify In Field

Höweler + Yoon Architecture, founded in 2001 and based in Boston, gained early praise for ephemeral and interactive public projects and today is recognized for striking works that combine conceptual speculation and technological sophistication. The firm's impressive body of work has expanded the scope of design beyond traditional disciplinary boundaries and has won them numerous national and international awards. Verify in Field is Höweler + Yoon Architecture's second book. Its title derives from a notational convention on architectural drawings to indicate that the information is subject to unknown conditions in the field. The book highlights verification as an integral part of the design process and demonstrates it as a productive tool to test ideas and act on the world. For both disciplinary and contractual reasons, the instruments of design--drawings, models, and prototypes--operate on the world at a distance. Techniques of prototyping, measurement, feedback, negotiation, and intervention inform the diverse output of the studio. Verify in Field features recent designs by Höweler + Yoon architecture, including such projects as the Memorial to Enslaved Laborers at the University of Virginia; a floating outdoor classroom in Philadelphia; the MIT Museum;; and a pedestrian bridge in Shanghai's Expo Park. The book also examines the discipline's pressing questions, as they relate to verification, uncertainty, and design agency, in a series of essays by Eric Höweler and J. Meejin Yoon on topics that include means and methods, the public realm, energy and environments, the construction detail, and social media. These themes are echoed in conversations with collaborators, historians, and theorists: Adam Greenfield, Nader Tehrani, Kate Orff, Daniel Barber, and Ana Miljacki.

The problem of verifying predictions of fire behavior, primarily rate of spread, is discussed in terms of the fire situation for which predictions are made, and the type of fire where data are to be collected. Procedures for collecting data and performing analysis are presented for both readily accessible fires where data should be complete, and for inaccessible fires where data are likely to be incomplete. The material is prepared for use by field units, with no requirements for special equipment or computers. Procedures for selecting the most representative fuel model, for overall evaluation of prediction capability, and for developing calibration coefficients to improve future predictions are presented. Illustrated examples from several fires are included. The material is a companion publication to the fire prediction manual titled, 'INT-GTR-143: How to predict the spread and intensity of forest and range fire' by R. C. Rothermel.

An authoritative overview of the requirements and costs of monitoring, reporting and verifying emissions from industry to regional and national levels.

The objective of this work on the mechanics of aeronautical solids, materials and structures is to give an overview of the principles necessary for sizing of structures in the aeronautical field. It begins by introducing the classical notions of mechanics: stress, strain, behavior law, and sizing criteria, with an emphasis on the criteria specific to aeronautics, such as limit loads and ultimate loads. Methods of resolution are then presented, and in particular the finite element method. Plasticity is also covered in order to highlight its influence on the sizing of structures, and in particular its benefits for design criteria. Finally, the physics of the two main materials of aeronautical structures, namely aluminum and composite materials, is approached in order to clarify the sizing criteria stated in the previous chapters. Exercises, with detailed corrections, then make it possible for the reader to test their understanding of the different subjects.
