Reliability

P(A)

Today at the usual hour we introduce the project which will require harvesting power reliability statistics from any and all educational settlements willing to share their data.  As the links before demonstrate, we have worked in this domain for many years.  Join us with the login credentials at the upper right of our home page.

Indiana University Internet Archive: “A Mathematical Theory of Reliability” by Richard E. Barlow and Frank Proschan (1965)

This paper introduced the concept of reliability theory and established a mathematical framework for analyzing system reliability in terms of lumped parameters. It defined important concepts such as coherent systems, minimal cut sets, and minimal path sets, which are still widely used in reliability engineering.

IEEE Recommended Practice for the Design of Reliable Industrial and Commercial Power Systems

“Railroad Sunset” | Edward Hopper

We are tooling up to update the failure rate tables of IEEE 493 Design of Reliable Industrial and Commercial Power Systems; collaborating with project leaders but contributing to an essential part of the data design engineers use for scaling their power system designs.  The project is in its early stages.  We are formulating approaches about how to gather data for assemble a statistically significant data set.

“On the Mathematical Theory of Risk and Some Problems in Distribution-Free Statistics” by Frank Proschan (1963): This paper introduced the concept of increasing failure rate (IFR) and decreasing failure rate (DFR) distributions, which are crucial in reliability modeling and analysis.

“Reliability Models for Multiple Failures in Redundant Systems” by John F. Meyer (1965): This paper addressed the problem of reliability analysis for redundant systems, which are systems with multiple components designed to provide backup in case of failure.

“Reliability of Systems in Series and in Parallel” by A. T. Bharucha-Reid (1960): This work analyzed the reliability of systems composed of components arranged in series and parallel configurations, which are fundamental building blocks of more complex systems.

“A Stochastic Model for the Reliability of Modular Software Systems” by John E. Gaffney, Jr. and Thomas A. Dueck (1980): This paper introduced one of the earliest models for software reliability, extending the concepts of reliability theory to the field of software engineering.

“Redundancy Techniques for Computing Systems” by John von Neumann (1956): This report by the pioneering computer scientist John von Neumann explored the use of redundancy techniques, such as triple modular redundancy, to improve the reliability of computing systems.

The World Soil Museum hosts a range of educational programs and workshops for students, researchers, and other visitors who are interested in learning more about soil science. These programs cover topics such as soil classification, soil management, and soil conservation, and they are designed to help people understand the vital role that soils play in supporting agriculture, ecosystems, and human societies around the world.

 

Getting to Know Your Soil

Gallery: Great Lakes

The Great Lakes contain enough fresh water to cover the land area of the entire United States under 3 meters of water.

We collect 15 video presentations about Great Lake water safety and sustainability prepared by the 8 Great Lake border state colleges and universities and their national and international partners in Canada.

When the wicked problems of peace and economic inequality cannot be solved, political leaders, and the battalions of servile administrative muckety-mucks who report to them, resort to fear-mongering about an imagined problem to be solved centuries hence assuming every other nation agrees on remedies of its anthropogenic origin.  We would not draw attention to it were it not that large tranches of the global academic community are in on the grift costing hundreds of billions in square-footage for research and teaching hopelessness to our children and hatred of climate change deniers.

Before the internet is scrubbed of information contrary to climate change mania, we recommend a few titles:

The Business of Standards Never Stops

Standards for a Kitchen Symphony | November/December 2024

ASTM International (formerly known as the American Society for Testing and Materials) is a globally recognized organization that develops and publishes technical standards for a wide range of products, systems, and services. These standards are used by manufacturers, regulatory bodies, and other stakeholders to ensure that products and services are safe, reliable, and of high quality.

In the field of measurement science, ASTM plays an important role in developing standards and guidelines for measurement techniques and practices. These standards cover a wide range of topics related to measurement science, including the calibration of instruments, the characterization of measurement systems, and the validation of measurement results. They are used by researchers, engineers, and other professionals in academia, industry, and government to ensure that measurements are accurate, precise, and reliable.

ANSI Public Review

 

ASTM standards for measurement science are developed through a process that involves input from experts in the field, including researchers, industry professionals, and regulatory bodies. These standards are updated regularly to reflect advances in measurement science and technology, as well as changes in industry and regulatory requirements.  This is a far better way to discover and promulgate leading practice.  In fact, there are regulations intended to restrain the outsized influence of vertical incumbents in legislative precincts where market-making happens.
