DTIC ADA045939: Automatic Data Entry Analysis.
Speed and accuracy have been compared for isolated-word voice recognition, keyboard, and graphical menu data entry systems. One entry task involved simple copying of numeric and alphanumeric data strings. A second was a simulation of complex flight data entry scenario. The factors evaluated included voice response feedback and prompting, hand occupation during data entry, and subject experience. Keyboard provided the fastest and most accurate entry of numeric data strings and the fastest entry of alphanumeric strings by subjects with keyboard experience in the simple scenario, but was slow relative to voice and graphical menu for entry of words by inexperienced subjects in the complex scenario. Voice entry provided the lowest error rate for entry of alphanumeric data strings in the simple scenario primarily because of its greater immunity to reading errors. In the complex scenario, voice was faster than keyboard for inexperienced subjects, and had a similar operational error rate, but had a substantially higher error rate before correction. Graphical menu ranked between keyboard and voice in most of the simple scenario measures, except that it was least accurate with alphanumeric data, and had the lowest entry speed for long strings.

ERIC ED249251: Instrument Formatting with Computer Data Entry in Mind.
Different formats for four types of research items were studied for ease of computer data entry. The types were: (1) numeric response items; (2) individual multiple choice items; (3) multiple choice items with the same response items; and (4) card column indicator placement. Each of the 13 experienced staff members of a major university's Data Entry office rated format examples for ease of entry, identified the most preferred example, and answered other questions regarding design preference. Findings indicate the preferred instrument format would include: dashes or blanks with no embedded periods (continuous lines) for numeric or dollar amounts; vertical listing of response options for individual multiple choice items with a blank beside each option to be checked and the card column indicators in the margin; columnar listings of numeric codes to be circled and response labels at column heads for multiple choice items with the same response options; and card column indicators placed in the right margin. Instrument design utilizing these preferred elements should be consistent in response format and in card column indicator placement. Format preference does not insure the fastest or most accurate entry, but should be one of several instrument design considerations. The questionnaire used for this study is appended. (BS)

An expanded model of HIV cell entry phenotype based on multi-parameter single-cell data.
This article is from Retrovirology , volume 9 . Abstract Background: Entry of human immunodeficiency virus type 1 (HIV-1) into the host cell involves interactions between the viral envelope glycoproteins (Env) and the cellular receptor CD4 as well as a coreceptor molecule (most importantly CCR5 or CXCR4). Viral preference for a specific coreceptor (tropism) is in particular determined by the third variable loop (V3) of the Env glycoprotein gp120. The approval and use of a coreceptor antagonist for antiretroviral therapy make detailed understanding of tropism and its accurate prediction from patient derived virus isolates essential. The aim of the present study is the development of an extended description of the HIV entry phenotype reflecting its co-dependence on several key determinants as the basis for a more accurate prediction of HIV-1 entry phenotype from genotypic data. Results: Here, we established a new protocol of quantitation and computational analysis of the dependence of HIV entry efficiency on receptor and coreceptor cell surface levels as well as viral V3 loop sequence and the presence of two prototypic coreceptor antagonists in varying concentrations. Based on data collected at the single-cell level, we constructed regression models of the HIV-1 entry phenotype integrating the measured determinants. We developed a multivariate phenotype descriptor, termed phenotype vector, which facilitates a more detailed characterization of HIV entry phenotypes than currently used binary tropism classifications. For some of the tested virus variants, the multivariant phenotype vector revealed substantial divergences from existing tropism predictions. We also developed methods for computational prediction of the entry phenotypes based on the V3 sequence and performed an extrapolating calculation of the effectiveness of this computational procedure. Conclusions: Our study of the HIV cell entry phenotype and the novel multivariate representation developed here contributes to a more detailed understanding of this phenotype and offers potential for future application in the effective administration of entry inhibitors in antiretroviral therapies.

DTIC ADA023616: Prediction of Vertical Water-Entry Forces on Ogives from Cone Data
An empirical method of predicting the drag coefficient for vertical water entry of pointed shapes is presented. The drag coefficient versus depth function is generated from experimental results of the vertical entry of cones of various angles. Comparison with experimental results shows that the predicted values are accurate to within + or - 25 percent. A computer program for predicting the water-entry drag coefficient of many shapes is included.

DTIC ADA101823: An Experiment in Voice Data Entry for Imagery Interpretation Reporting.
This thesis investigated the feasibility of voice data entry for imagery intelligence order of battle reporting. Time, accuracy, and efficiency were measured for 20 subjects in an experiment physically simulating the use of a light table, optics, and an interactive computer system for reporting. A Threshold Technology Inc. T600 voice recognition system was used for a large, unstructured vocabulary (255 words) of unclassified Soviet/Warsaw Pact equipment names, alphanumerics, and editing commands. The T600 recognition accuracy for this experiment was 97.0% without rejects, and 95.5% with rejects. Buffered voice and unbuffered voice modes of the T600 were evaluated with typing: buffered voice was 58% faster, and unbuffered voice 41% faster than typing. Voice was also found to be as accurate as typing for writing short order of battle reports. Finally, subjects preferred voice for several criteria evaluated before and after the experiment.

NASA Technical Reports Server (NTRS) 19830001839: Preliminary analysis of STS-4 entry flight data
A preliminary analysis of the data obtained during entry of the STS-4 Flight was completed. Planned maneuvers were flown during this flight to increase the quality of stability and control analysis, similar to the techniques used during STS-3. The derivatives obtained from STS-4 agreed fairly well with the derivatives obtained on previous flights. The dependence of aileron effectiveness on a elevon position above a Mach number of 10 seen on STS-3 was conclusively verified on STS-4. CSS Mode was engaged to fly the heading alignment circle. After engagement, several cycles of a low amplitude pilot induced oscillation (1 deg/sec) at about 0.3 hertz can be seen. No PIO suppressor activity was seen between preflare and touchdown. This approach demonstrates the advantage of the shallow final glideslope approach. In this type of approach, the pilot is not required to make accurate altitude judgments since an acceptable landing can be made without performing the final flare.

NASA Technical Reports Server (NTRS) 20070032067: Numerical Study of Flow Augmented Thermal Management for Entry and Re-Entry Environments
The use of a flow augmented thermal management system for entry and re-entr environments is one method for reducing heat and drag loads. This concept relies on jet penetration from supersonic and hypersonic counterflowing jets that could significantly weaken and disperse the shock-wave system of the spacecraft flow field. The objective of this research effort is to conduct parametric studies of the supersonic flow over a 2.6% scale model of the Apollo capsule, with and without the counterflowing jet, using time-accurate and steady-state computational fluid dynamics simulations. The numerical studies, including different freestream Mach number angle of attack counterflowing jet mass flow rate, and nozzle configurations, were performed to examine their effect on the drag and beat loads and to explore the counternowing jet condition. The numerical results were compared with the test data obtained from transonic blow-down wind-tunnel experiments conducted independently at NASA MSFC.

DTIC ADA569303: Radiation Database for Earth and Mars Entry
This lecture presents the general guidelines we have followed to build up an exhaustive and accurate spectroscopic database for radiative transfer in air and CO2-N2 plasma applications, including atmospheric entries. This High Temperature Gas Radiation (HTGR) database includes bound-bound atomic, diatomic and polyatomic (in particular CO2) transitions, bound-free transitions resulting from various mechanisms, and free-free transitions. The covered spectral range is 1000{200,000 cm-1 and the targeted maximum temperature is 30,000 K. A particular attention is given to the selection of the most reliable fundamental data (line strengths for atoms and ions, electronic transition moment functions and spectroscopic constants for diatomic molecules, cross sections for continuum radiation), and to accurate prediction of atomic and ion line shapes which are strongly self-absorbed. The spectroscopic database is applied in the last part of this lecture to the simulation of Fire II experiment as an example of earth entry, and to the prediction of a Mars entry simulation. We discuss in these applications the spectral distribution of radiative uxes from the infrared to the VUV, the effects of optical thicknesses and self-absorption, and the effects of chemical nonequilibrium on continuum radiation.

A Light-Weight Inflatable Hypersonic Drag Device for Planetary Entry
The author has analyzed the use of a light-weight inflatable hypersonic drag device, called a ballute, (balloon parachute) for flight in planetary atmospheres, for entry, aerocapture, and aerobraking. Studies to date include missions to Mars, Venus, Earth, Saturn, Titan, Neptune and Pluto. Data on a Pluto lander and a Mars orbiter will be presented to illustrate the concept. The main advantage of using a ballute is that aero deceleration and heating in atmospheric entry occurs at much smaller atmospheric density with a ballute than without it. For example, if a ballute has a diameter 10 times as large as the spacecraft, for unchanged total mass, entry speed and entry angle,the atmospheric density at peak convective heating is reduced by a factor of 100, reducing the peak heating by a factor of 10 for the spacecraft, and a factor of about 30 for the ballute. Consequently the entry payload (lander, orbiter, etc) is subject to much less heating, requires a much reduced thermal protection system (possibly only an MLI blanket), and the spacecraft design is therefore relatively unchanged from its vacuum counterpart. The heat flux on the ballute is small enough to be radiated at temperatures below 800 K or so. Also, the heating may be reduced further because the ballute enters at a more shallow angle, even allowing for the increased delivery angle error. Added advantages are a smaller mass ratio of entry system to total entry mass, and freedom from the low-density and transonic instability problems that conventional rigid entry bodies suffer, since the vehicle attitude is determined by the ballute, usually released at continuum conditions (hypersonic for an orbiter, and subsonic for a lander). Also, for a lander the range from entry to touchdown is less, offering a smaller footprint. The ballute derives an entry corridor for aerocapture by entering on a path that would lead to landing, and releasing the ballute adaptively, responding to measured deceleration, at a speed computed to achieve the desired orbiter exit conditions. For a lander an accurate landing point could be achieved by providing the lander with a small gliding capacity, using the large potential energy available from being subsonic at high altitude. Alternatively the ballute can be retained to act as a parachute or soft-landing device, or to float the payload as a buoyant aerobot. As expected, the ballute has smaller size for relatively small entry speeds, such as for Mars, or for the extensive atmosphere of a low-gravity planet such as Pluto. The author will discuss presently available ballute materials and a development program of aerodynamic tests and materials that would be required for ballutes to achieve their full potential.
