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

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

Port Everglades Macroinvertebrate Monitoring: Monitoring of Benthic Macroinvertebrate Assemblages at the Southport Turning Basin and Adjacent Areas of John U. Lloyd State Recreation Area: August 1993 (Including a Summary of Previous Survey Results, 1991-1993)

This report documents the August 1993 monitoring of benthic macroinvertebrate assemblages in the Port Everglades Southport turning basin vicinity and adjacent areas of John U. Lloyd State Recreation Area. This is the fifth monitoring effort of the series carried out by Nova University Oceanographic Center. Sampling was carried out chiefly during 2-12 August. Hand collections and a few crab survey stations were delayed until 2-12 October primarily because of weather and tidal constraints

Structural modeling of aircraft tires

A theoretical and experimental investigation of the feasibility of determining the mechanical properties of aircraft tires from small-scale model tires was accomplished. The theoretical results indicate that the macroscopic static and dynamic mechanical properties of aircraft tires can be accurately determined from the scale model tires although the microscopic and thermal properties of aircraft tires can not. The experimental investigation was conducted on a scale model of a 40 x 12, 14 ply rated, type 7 aircraft tire with a scaling factor of 8.65. The experimental results indicate that the scale model tire exhibited the same static mechanical properties as the prototype tire when compared on a dimensionless basis. The structural modeling concept discussed in this report is believed to be exact for mechanical properties of aircraft tires under static, rolling, and transient conditions

Port Everglades Macroinvertebrate Monitoring: Monitoring of Benthic Macroinvertebrate Assemblages at the Southport Turning Basin and Adjacent Areas of John U. Lloyd State Recreation Area: January 1993: Final Version

This report documents the January 1993 monitoring of benthic macroinvertebrate assemblages in the Port Everglades Southport turning basin vicinity and adjacent areas of John U. Lloyd State Recreation Area. This is the fourth monitoring effort of the series carried out by Nova University Oceanographic Center. Sampling was carried out during 4-15 January and 1-22 February 1993, the extended period due chiefly to weather and tidal constraints. Comparison with results of preceding survey efforts will be included in the annual report following the August 1993 survey. The section treating the Ponar grab samples is now complete: identifications of the remaining groups of invertebrates (oligochaetes, sipunculans, cumaceans, nemertines) have been received from consultants, and the data have been incorporated, along with calculation of diversity indices and evenness values

Port Everglades Macroinvertebrate Monitoring: Monitoring of Benthic Macroinvertebrate Assemblages at the Southport Turning Basin and Adjacent Areas of John U. Lloyd State Recreation Area: August 1992 (With a Summary of the August 1991 and January 1992 Surveys)

This report documents the August 1992 monitoring of benthic macroinvertebrate assemblages in the Pon Everglades Southpon turning basin vicinity and adjacent areas of John U. Lloyd State Recreation Area. This is the third monitoring effort of the series carried out by Nova University Oceanographic Center. Sampling was carried out chiefly during the first two weeks of August 1992. Hurricane Andrew and its aftermath resulted in delays in sampling at several sites and in analyzing data. A two-week postponement in submission deadline was requested and granted. An additional postponement, to 31 January 1992, was requested due to a move at the Smithsonian Institution that prevented some consultants from returning identifications on time. A history of the monitoring project since its inception in 1988 was given in the report submitted December 1991 and is included here again for reference. This report also includes the tabular data for the two previous surveys (August 1991 and January 1992) together with a discussion of all three surveys carried out by Nova University. Please note modifications to the Ponar grab sample data for the January 1992 survey. In the original report for that survey, we inadvertently omitted doubling the dataset from large volume samples of which we sorted 50% (following the methodology described below). Diversity indices were not affected

Port Everglades Macroinvertebrate Monitoring: Monitoring of Benthic Macroinvertebrate Assemblages at the Southport Turning Basin and Adjacent Areas of John U. Lloyd State Recreation Area: January 1992

This repurt documents the January 1992 monitoring of benthic macroinvertebrate assemblages in the Port Everglades Southport turning basin vicinity and adjacent areas of John U. Lloyd State Recreation Area. This is the second monitoring effort of the series carried out by Nova University Oceanographic Center. Sampling was carried out during the first two weeks of January 1992. A history of the monitoring project since its inception in 1988 was given in the previous report (submitted December 1991)
