An assembly to provide a time reference for the JPL Network Operations Control Center, Real-Time

A device is described which provides the value of date coordinated universal time (date UTC) to the JPL Network Operations Control Center, Real Time (NOCC-RT) facility. The NOCC-RT is the real time portion of the NOCC upgrade task. The time scale is generated in the NOCC-RT clock processor; however, there is a continuous reference to UTC, as realized by the National Institute of Standards and Technology and transmitted by Earth orbiting satellites. An important functional design requirement is the 99.9 pct. availability

Summary of a flight-test evaluation of the CL-84 tilt-wing V/STOL aircraft

Flight test evaluation of second generation CL-84 tilt-wing aircraft in hover, transition, and cruise mode

Arkansas Wheat Cultivar Performance Tests 2013-2014

Wheat cultivar performance tests are conducted each year in Arkansas by the Arkansas Agricultural Experiment Station, Department of Crop, Soil and Environmental Sciences. The tests provide information to companies developing cultivars and/or marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for small-grain producers

Optimal symmetric flight with an intermediate vehicle model

Optimal flight in the vertical plane with a vehicle model intermediate in complexity between the point-mass and energy models is studied. Flight-path angle takes on the role of a control variable. Range-open problems feature subarcs of vertical flight and singular subarcs. The class of altitude-speed-range-time optimization problems with fuel expenditure unspecified is investigated and some interesting phenomena uncovered. The maximum-lift-to-drag glide appears as part of the family, final-time-open, with appropriate initial and terminal transient exceeding level-flight drag, some members exhibiting oscillations. Oscillatory paths generally fail the Jacobi test for durations exceeding a period and furnish a minimum only for short-duration problems

Detection of quantum light in the presence of noise

Detection of quantum light in the presence of dark counts and background radiation noise is considered. The corresponding positive operator-valued measure is obtained and photocounts statistics of quantum light in the presence of noise is studied.Comment: 4 pages, 1 figure; misprints correcte

The Six Dimensions of Wellness and Cognition in Aging Adults

Objective: Examine how wellness in six dimensions (occupational, social, intellectual, physical, emotional, and spiritual) protects cognition in aging adults. Background: cognitive impairment increases with age. Baby boomers represent a significant percent of the population at risk for cognitive impairment. Cognitive impairment has a negative impact on nursing resources, health care finances, patient mortality, and quality of life. Wellness and prevention is one focus of Institute of Medicine’s vision for the future of nursing. Method: Literature was retrieved from Cumulative Index to Nursing and Allied Health Literature and MEDLINE. Research that examined the affect of wellness in each of the six dimensions on cognition in older adults was included. Results: One or more of the following may protect cognition in aging: midlife occupation complexity, marriage, social networks, formal education, intellectual activities, physical activity, healthy nutrition, motivational ability, purpose in life, and spirituality. Conclusion: Wellness in one or more of the six dimensions may protect cognition in aging. The cognitive protective benefits may increase when wellness in more than one dimension is demonstrated. High wellness in one dimension may protect cognition by compensating for low wellness in another dimension. The interconnectedness of each of the dimensions signifies the importance of evaluating older adults holistically. Wellness throughout the life span may result in improved cognition in aging. Application: Future research is needed to examine the relationship between the six dimensions of wellness and cognition, and to determine if one dimension of wellness is a significant predictor of cognitive health in aging adults
