Development of high precision direct shear apparatus for liquefaction testing

Development of High Temperature Multiproperty Apparatus

The development of the multiproperty apparatus to include high temperature determinations of specific heat, enthalpy and thermal diffusivity in addition to the properties already measured is described. The latter properties include thermal conductivity, electrical resistivity, Lorenz ratio, total hemispherical emittance, spectral emittance at 0.65 microns and Thomson coefficient. The specific h...

Reaction Engineering of Direct Coal Liquefaction

Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to produce synthetic fuels when there was no oil allowed into the country. Since then, it has been studied in the United States and many different technologies have been investigated. Since the US is rich in coal resources, this is one way to be energy independent. Most of the dev...

Development and testing of application systems for precision

Introduction: Precision or “site-specific” management of ag production requires application of fertilizer, pesticides, water and other inputs on spatial scales much smaller than previously used. The concept is simple; by using accurate navigation and positioning to guide collection, sensors for crop yield, soil properties and other conditions can be used to develop maps or databases of crop res...

An Extensible Technique for High-Precision Testing of Recovery Code

Marinescu said that the real problem when doing faultinjection testing is finding good strategies to inject faults. He then focused on answering the when, where, and what to inject questions. He first introduced the notion of injection triggers, a mechanism that allows testers to specify with an arbitrary degree of precision when to inject. Then he showed a static analysis tool that can automat...
