    The access schema developed to access both individual switch functions as well as automated or semiautomated procedures for the orbital maneuvering system and electrical power and distribution and control system discussed and the operation of the system is described. Feasibility tests and analyses used to define display parameters and to select applicable hardware choices for use in such a system are presented and the results are discussed

    Application of multi-function display and control technology

    The NASA orbiter spacecraft incorporates a complex array of systems, displays, and controls. The incorporation of discrete dedicated controls into a multifunction display and control system (MFDCS) offers the potential for savings in weight, power, panel space, and crew training time. Technology identified as applicable to a MFDCS is applied to the orbiter orbital maneuvering system (OMS) and the electrical power distribution and control system (EPDCS) to derive concepts for a MFDCS design. Several concepts of varying degrees of performance and complexity are discussed and a suggested concept for further development is presented in greater detail. Both the hardware and software aspects and the human factors considerations of the designs are included

    Development of preliminary design concept for a multifunction display and control system for the Orbiter crew station. Task 4: Design concept recommendation

    Application of multifunction display and control systems to the NASA Orbiter spacecraft offers the potential for reducing crew workload and improving the presentation of system status and operational data to the crew. A design concept is presented for the application of a multifunction display and control system (MFDCS) to the Orbital Maneuvering System and Electrical Power Distribution and Control System on the Orbiter spacecraft. The MFDCS would provide the capability for automation of procedures, fault prioritization and software reconfiguration of the MFDCS data base. The MFDCS would operate as a stand-alone processor to minimize the impact on the current Orbiter software. Supervisory crew command of all current functions would be retained through the use of several operating modes in the system. Both the design concept and the processes followed in defining the concept are described

    State Welfare-to-Work Policies for People with Disabilities

    This study represents a first attempt to provide a nationwide overview of welfare-to-work policies for individuals with disabilities and caregivers. The major findings of this report are: (c) The majority of states have changed their work participation policies to require participation among some individuals with disabilities and caregivers who were previously exempt. (c) States are in the early stages of making decisions about who should be required to participate in welfare-to-work services, who should be expected to move off welfare within 60 months, and what services will best help recipients achieve this objective

    Economically Feasible Crop Production Alternatives to Peanuts in Southwestern Oklahoma

    Get PDF
    Changes in the U.S. peanut program have resulted in drastically decreased planted acres and forced many peanut producers in the Southwest to consider alternative crops. This study examined the economic risk associated with producing peanuts and common alternatives to peanuts. Seedless watermelon is an alternative for risk preferring farmers whereas, irrigated peanut is the best choice for risk averse farmers.Crop Production/Industries,

    Financial Analysis Tools for On-Farm and Off-Farm Commercial Kitchens

    Get PDF
    This article describes two spreadsheet-based tools designed to help farmers evaluate the viability of building and operating commercial kitchens, on-farm and off-farm, to meet the demand for locally processed foods. Both tools let users define the processing activities and kitchen capacity, including the appropriate equipment, personnel needs, days of operation, and processed products. The on-farm kitchen model provides annual return estimates, allowing users to change recipes each year to match changes in annual farm production. The off-farm kitchen model assumes a stand-alone facility with depreciation schedules, loan amortization schedules, 10-year profit/loss projections, and various measures of return on investment

    Brain Control of Functional Reach in Healthy Adults and Stroke Survivors

    Get PDF
    Purpose: Recovery of the most basic shoulder-flexion/elbow-extension components of functional reach is critical for effective arm function following stroke. In order to understand the mechanisms of motor recovery, it is important to characterize the pattern of brain activation during the reach task. Methods: We evaluated 11 controls and 23 moderately to severely impaired chronic stroke survivors (\u3e6 months), with impaired shoulder flexion and elbow extension. Measures were acquired for Arm Motor Ability Test (AMAT) and functional Magnetic Resonance Imaging (fMRI) during the basic shoulder/elbow reach. Results: First, in controls, lateralization of fMRI signal during the reach task was less pronounced in comparison to other tasks, and even further diminished after stroke (p \u3c 0.05). Second, for the stroke group, centroid locations, for specific ipsilesional (contralateral to working limb) motor-sensory regions and for contralesional (ipsilateral to working arm) somatosensory and SMA regions, were significantly more distant from the centroid location of average healthy controls (p \u3c 0.05). Third, both greater activation volume and greater degree of signal intensity were correlated with better motor function in stroke survivors. Conclusions: These findings can be useful in guiding the development of more targeted brain training methods for recovery of impaired reach coordination
