Low-Sloped Roofing Research Plan (open access)

Low-Sloped Roofing Research Plan

Abstract: This report presents a long-range plan for roofing research. The plan was developed in response to a need for roofing research addressing major materials problems and changes in low-sloped roofing materials technology. The intent of the plan is to establish the technical basis for developing standards and minimum levels of performance to assist in the selection of cost-effective and durable roofing materials. Four major areas of needed research are identified: (1) low-sloped roofing systems, (2) roofing membranes including single-ply and built-up, (3) thermal insulation for roofing systems, and (4) condition assessment and repair of roofs. Within each research area, a goal is given as well as a number of objectives to achieve the goal. A recommended approach to accomplish each objective is also given.

Measurement & Analysis of Productivity Growth: a Synthesis of Thought (open access)

Measurement & Analysis of Productivity Growth: a Synthesis of Thought

Abstract: Productivity is one of the most important factors influencing our economic well-being. Productivity growth is essential to a higher standard of living and is vital to a sound economic and political environment. However, there has been a slowdown in the growth of productivity in the United States since the mid-1960s. This slowdown has caused concern among policy makers and researchers. Accordingly, several questions persist both in policy and academic circles. Why has productivity been slowing? and What can be done to reverse this trend? The purpose of this report is to address broadly the first of these two questions by surveying and synthesizing the vast literature on the measurement and determinants of productivity. This review is intended to be a source document for those interested in the measurement and analysis of productivity growth. The report is divided into five sections. In the first section, the importance of productivity growth on economic activity is discussed. In the second section, the so called "facts" about patterns of measured productivity growth in the United States are presented. In the third section, the methods currently used for calculating productivity indices are summarized. In the fourth section, the literature related to the determinants of …

Theory and Application of Expert Systems in Emergency Management Operations

Abstract: The First Symposium on The Theory and Application of Expert Systems in Emergency Management, held at the Department of Commerce, Washington, D.C. (April 24 and 25, 1985) was funded by the Federal Emergency Management Agency and organized by the National Bureau of Standards' Operations Research Division. The purpose of the symposium was to bring together researchers in expert systems, artificial intelligence, and emergency operations in a forum to review the concepts of expert systems and the problems of emergency management, with the objective of determining how expert systems can be used to augment the experience of local, State and Federal emergency managers faced with the difficult tasks of determining the best response to an emergency situation. Speakers addressed the following areas: The theory and uncertainty aspects of expert systems, artificial intelligence's future role in emergency management, technology for building and using expert systems, emergency management decisions and information needs and uses, applications of expert systems in the management of chemical spills and shipboard and coal mine fires, and the role and use of simulation in emergency management expert systems.

A User's Guide for RAPID, Reduction Algorithms for the Presentation of Incremental Fire Data

Abstract: The Voluminous amount of data than can be collected by automatic data acquisition systems during large scale fire tests requires the use of a digital computer for the reduction of data. RAPID is a stand-alone program specifically designed to convert raw instrument voltages collected during such tests into meaningful units. The reduced data can also be used alone or in combinations to obtain quantities that require more than minimal data reduction. The program is written with the ability to accept data from a user defined data acquisition system, with the ability to check the correctness of data included. Through the use of input data provided by the user, the data can be converted into meaningful scientific units. The data can then be presented in tabular or printer plot form, or stored for further processing. This user's guide provides detailed instructions for the use of the program.
