Mod I engine testing and test results, the test of a Mod I engine in the United States, Mod I engine characterization and analysis, Mod I Transient Test Bed fuel economy, Mod I-A engine performance are discussed. Stirling engine reference engine manufacturing and reduced size studies, components and subsystems, and the study and test of low-cost casting alloys are also covered. The overall program philosophy is outlined, and data and results are presented

Family Functioning and Psychological Well-Being in Vietnamese Adolescents

This paper presents an exploratory study that examines the influences of family functioning on the psychological well-being in a sample of Vietnamese adolescents. Thirty Vietnamese families from the King County area in the state of Washington participated in this study. Thirty adolescents between 13 and 19 years of age and 53 parents (27fathers and 26 mothers) responded to self-reported questionnaires. Data analysis was conducted to provide a descriptive picture of family and individual characteristics associated with Vietnamese adolescents\u27 psychological well-being. Gender differences were apparent with Vietnamese female adolescents reporting higher mean scores on depressive symptoms and lower mean scores on self-esteem. These findings are consistent with prior research on Euro- American adolescents, where females reported more depressive symptoms and lower self-esteem than did their male counterparts. Further, mean scores on adolescents\u27 reports of problems relating to parents were higher for females than males. These adolescents reported more family cohesiveness and parental supports, particularly from their fathers. Implications for future research, practice, and policy are also discussed

Automotive Stirling Engine Development Program

Program status and plans are discussed for component and technology development; reference engine system design, the upgraded Mod 1 engine; industry test and evaluation; and product assurance. Four current Mod 1 engines reached a total of 2523 operational hours, while two upgraded engines accumulated 166 hours

The major accomplishments were the completion of the Basic Stirling Engine (BSE) and the Stirling Engine System (SES) designs on schedule, the approval and acceptance of those designs by NASA, and the initiation of manufacture of BSE components. The performance predictions indicate the Mod II engine design will meet or exceed the original program goals of 30% improvement in fuel economy over a conventional Internal Combustion (IC) powered vehicle, while providing acceptable emissions. This was accomplished while simultaneously reducing Mod II engine weight to a level comparable with IC engine power density, and packaging the Mod II in a 1985 Celebrity with no external sheet metal changes. The projected mileage of the Mod II Celebrity for the combined urban and highway CVS cycle is 40.9 mpg which is a 32% improvement over the IC Celebrity. If additional potential improvements are verified and incorporated in the Mod II, the mileage could increase to 42.7 mpg
