In this expanded new edition of Living with Earthquakes, Robert Yeats, a leading authority on earthquakes in California and the Pacific Northwest, describes the threat posed by the Cascadia Subduction Zone, a great earthquake fault which runs for hundreds of miles offshore from British Columbia to northern California. New research...
Considerable progress ha been made in Computer-Aided Design (CAD) techniques to assist Mechanical Engineers in the detail design stages and adaptive redesign tasks. Currently, CAD tools support the designer in system layouts, sizing of components, drafting, analytical calculations, generating NC machining data and even motion or energy simulations. However, the...
Wildfires can create alternative pathways for forest development, and wildfires have expanded in size, frequency, intensity, and severity across the western United States. The purpose of this paper is to compare forest development of a mature Douglas-fir forest in western Oregon across fire severities. Postburn field measurements were collected in...
The meaning of life is an enduring philosophical question. This paper seeks to explore the thought of Albert Camus and Robert Nozick on the meaning of life and critically examine their contributions to philosophy. Camus begins with contemplating whether life is worth ending or worth living and concludes that only...
Background:

When pavement markings on roadways are removed, scarring can occur leaving behind traces of where the marking used to be called ghost lines. These ghost lines can confuse drivers on the roadway and divert their attention from the correct lane markings leading them into the false lane. Previous research has...
Pesticide chemists have recognized since the 1940's that ultraviolet light was deleterious to the insecticidal properties of certain compounds. However, it has been only within the last 15 years that a number of photodecomposition products of the chlorinated hydrocarbon
insecticides have been isolated and identified. The degradation of insecticides by...
A concurrency and resiliency control scheme for a distributed database system with replicated data is discussed. The scheme, true-copy token scheme, uses true-copy tokens in order to designate the physical data copies (true copies) that can be identified with the current logical data that are globally unique, and then it...
