This is a report that describes the population of Hawaiian monk seal in the French Frigate Shoals during 1980. The data collected includes reproduction rates and deaths.

This is a report based on the observational data collected from Laysan Island on the Hawaiian monk seal. The data collected comes from the observations between 1977 through 1980, reflecting the population and what influences its increase/decrease in number. This includes reproduction patterns and survival rates.

The purpose of the assessment is to provide background information on the Corps' practices, identify shortcomings in specifications, estimates, grout placement techniques, and, in general, to determine the effectiveness of the Corps' grouting programs. The report reviews past grouting projects and describes the planning, execution, and performance evaluation of the programs.

Parameters and operating conditions (a stability map) were determined for which a specific slip-joint design did not cause self-excited lateral vibration of the two cantilevered, telescoping tubes forming the joint. The joint design featured a localized annular constriction. Flowrate, modal damping, tube engagement length, and eccentric positioning were among the parameters tested. Interestingly, all self-excited vibrations could be avoided by following a simple design rule: place constrictions only at the downstream end of the annular region between the tubes. Also, overall modal damping decreased with increased flowrate, at least initially, for upstream constrictions while the damping increased for downstream constrictions.

The mathematical software effort bridges the gap between the discovery of numerical algorithms and the consumption of numerical software. The spectrum of activities is surprisingly wide, including tasks often associated with numerical analysis, program design and testing, programming practices, language standards, documentation standards, software organization, distribution methods, and even the specification of arithmetic engines. This paper highlights the most important accomplishments in the field over the last twenty years. It also examines current problems and future challenges posed by the rapid advance of technology.
