Computer program determines vibration in three-dimensional space of hydraulic lines excited by forced displacements

Computer program determines the forced vibration in three dimensional space of a multiple degree of freedom beam type structural system. Provision is made for the longitudinal axis of the analytical model to change orientation at any point along its length. This program is used by industries in which structural design dynamic analyses are performed

Native American Identity: A Review of Twenty-first Century Research

The purpose of this literature review is to exam research on Native American identity within the social sciences in the twenty-first century in order to identify trends in research topics, various perspectives, and potential future studies, through the review of a sample of 86 publications relating to the topic of Native American identity. The sample was retrieved utilizing three scholarly databases across a wide range of fields of study. Publications are examined by area of focus and publication year

Development of carbon slurry fuels for transportation (hybrid fuels, phase 2)

Slurry fuels of various forms of solids in diesel fuel are developed and evaluated for their relative potential as fuel for diesel engines. Thirteen test fuels with different solids concentrations are formulated using eight different materials. A variety of properties are examined including ash content, sulfur content, particle size distribution, and rheological properties. Attempts are made to determine the effects of these variations on these fuel properties on injection, atomization, and combustion processes. The slurries are also tested in a single cylinder CLR engine in both direct injection and prechamber configurations. The data includes the normal performance parameters as well as heat release rates and emissions. The slurries perform very much like the baseline fuel. The combustion data indicate that a large fraction (90 percent or more) of the solids are burning in the engine. It appears that the prechamber engine configuration is more tolerant of the slurries than the direct injection configuration
