"A rare insight into industrial planning on a huge scale...Excellent." --The Economist Rescuing Prometheus is an eye-opening and marvelously informative look at some of the technological projects that helped shape the modern world. Thomas P. Hughes focuses on four postwar projects whose vastness and complexity inspired new technology, new organizations, and new management styles. The first use of computers to run systems was developed for the SAGE air defense project. The Atlas missile project was so complicated it required the development of systems engineering in order to complete it. The Boston Central Artery/Tunnel Project tested systems engineering in the complex crucible of a large scale civilian roadway. And finally, the origins of the Internet fostered the collegial management style that later would take over Silicon Valley and define the modern computer industry. With keen insight, Hughes tells these fascinating stories while providing a riveting history of modern technology and the management systems that made it possible.

In the history of music there are seldom as rapid musical developments as we can find in Scriabin's works. In only 31 years Scriabin made a breathtaking development: in his early works he still uses a romantic tonal language, while his later works are far-reaching into the 20th century. Scriabin's development is gradual and consequent, each step can be derived from the preceding, thus connecting the music of the 19th and 20th centuries. He can be regarded as a key composer of his age.Harmony is the central factor in Scriabin's musical thinking. From harmony everything else is developed. It defines the form, also the melody and tone systems are developed from it.This book is concerned with the following basic issues: Which elements in Scriabin's harmony are new, and what has been derived from the tradition? Why is the development in Scriabin's works consequent, once started, why did it have to follow a certain course? Is there something elemental in Scriabin's way of thinking that pushes ahead this development?

Accurate, high-resolution fire behavior prediction is a critical component of fire management decision-making before and during fires. Prometheus is a deterministic fire growth simulation model that was developed to help fire managers to understand the probable consequences of their decisions. It uses spatial input data on topography (slope, aspect, and elevation), fuel types, and weather to simulate fire growth by applying Huygens principle of wave propagation to the rate-of-spread predictions from the Canadian Forest Fire Behavior Prediction System of the Canadian Forest Fire Danger Rating System. This approach produces detailed fire perimeters at user-specified display time step intervals. Each active vertex along the perimeter has corresponding fire behavior output. Exported fire perimeters are compatible with geographic information systems. Additionally, three interpolation techniques are available to produce optional raster fire behavior outputs. This report documents the structure of the Prometheus model and an assessment of its performance. The report includes a general discussion of approaches to the modeling of fire growth simulation and explains the vector propagation technique used in Prometheus. The limitations and assumptions of applying the model, as well as the most appropriate directions for future research, are also discussed.

The development of a national science policy for Canada – and the priorities to be set within any such policy – have been topics of a mounting debate within government and the scientific community. The questions involved are of concern in every country today: Can governments now afford to support laissez-faire 'pure' research to any extent? Or rather, should available resources be allocated to mission-oriented studies determined by government-established national goals? Professor Hayes assesses the limitations and prospects for success of attempts to impose a pattern of planning on Canadian science and critically examines the reports of the Glassco Commission, the examiners for the OECD, the Lamontagne Committee, and the Science Council, as well as of several university-sponsored groups. The power of the Treasury Board and other parts of the control system also receive attention. Most reports on Canadian science policy have been productions of federal agencies. Of the outside opinions, with a few notable exceptions, analyses and proposals about the natural sciences have been put forward by social scientists. The author, a scientist and former senior servant who has had experience in the research and administration of natural science both in the university and government, makes a unique, personal analysis of the attempts in Canada to impose national planning and controls over the historical free enterprise system of scientific research and development.

Get up to speed with Prometheus, the metrics-based monitoring system used by tens of thousands of organizations in production. This practical guide provides application developers, sysadmins, and DevOps practitioners with a hands-on introduction to the most important aspects of Prometheus, including dashboarding and alerting, direct code instrumentation, and metric collection from third-party systems with exporters. This open source system has gained popularity over the past few years for good reason. With its simple yet powerful data model and query language, Prometheus does one thing, and it does it well. Author and Prometheus developer Brian Brazil guides you through Prometheus setup, the Node exporter, and the Alertmanager, then demonstrates how to use them for application and infrastructure monitoring. Know where and how much to apply instrumentation to your application code Identify metrics with labels using unique key-value pairs Get an introduction to Grafana, a popular tool for building dashboards Learn how to use the Node Exporter to monitor your infrastructure Use service discovery to provide different views of your machines and services Use Prometheus with Kubernetes and examine exporters you can use with containers Convert data from other monitoring systems into the Prometheus format
