    A Low-speed Investigation of an Annular Transonic Air Inlet

    Get PDF
    Low-speed wind-tunnel tests were conducted as preliminary steps in the study of fuselage-air-inlet arrangements believed suitable for use at transonic speeds. The forward part of the model consisted of an NACA 1-85-050 cowling located at the base of the long protruding fuselage nose designed to maintain substream surface velocities everywhere ahead of the entrance and thereby to avoid or minimize adverse boundary-layer-shock interaction effects up to low supersonic speeds. Pressure-recovery and surface-pressure measurements are presented for the model with three fuselage nose shapes for ranges of angle of attack and inlet-velocity ratio useful for high-speed fligh

    Heavy ion induced Single Event Phenomena (SEP) data for semiconductor devices from engineering testing

    The accumulation of JPL data on Single Event Phenomena (SEP), from 1979 to August 1986, is presented in full report format. It is expected that every two years a supplement report will be issued for the follow-on period. This data for 135 devices expands on the abbreviated test data presented as part of Refs. (1) and (3) by including figures of Single Event Upset (SEU) cross sections as a function of beam Linear Energy Transfer (LET) when available. It also includes some of the data complied in the JPL computer in RADATA and the SPACERAD data bank. This volume encompasses bipolar and MOS (CMOS and MHNOS) device data as two broad categories for both upsets (bit-flips) and latchup. It also includes comments on less well known phenomena, such as transient upsets and permanent damage modes

    Test report for single event effects of the 80386DX microprocessor

    Get PDF
    The Jet Propulsion Laboratory Section 514 Single Event Effects (SEE) Testing and Analysis Group has performed a series of SEE tests of certain strategic registers of Intel's 80386DX CHMOS 4 microprocessor. Following a summary of the test techniques and hardware used to gather the data, we present the SEE heavy ion and proton test results. We also describe the registers tested, along with a system impact analysis should these registers experience a single event upset

    An inexpensive, light weight fiber optic accelerometer to convert input mechanical motion (e.g. acceleration) into digitized optical output signals. The output of the accelerometer may be connected directly to data processing apparatus without the necessity of space consuming analog to digital interface means

    Fiber optic temperature sensor

    An inexpensive, lightweight fiber optic micro-sensor that is suitable for applications which may require remote temperature sensing. The disclosed temperature sensor includes a phosphor material that, after receiving incident light stimulation, is adapted to emit phosphorescent radiation output signals, the amplitude decay rate and wavelength of which are functions of the sensed temperature

    Earnings Surprises and the Options Market

    Get PDF
    Numerous articles over the past few decades have documented a consistent relationship between earnings surprises and subsequent stock price performance. [See, for example, Ball and Brown (1968), Rendleman, Jones, and Latane (1982), Foster, Olsen, and Shevlin (1984), and Bernard and Thomas (1989).] Specifically when firms announce quarterly earnings figures that are higher (lower) than market expectations, as proxied by either mechanical time-series models or commercially available analysts’ forecasts, the stock price performance following the announcement tends to be abnormally good (bad). This phenomenon is referred to as post-earnings-announcement drift or the standardized unexpected earnings effect, SUE for short
