Electrolysis propulsion has been recognized over the last several decades as a viable option to meet many satellite and spacecraft propulsion requirements. This technology, however, was never used for inspace missions. In the same time frame, water based fuel cells have flown in a number of missions. These systems have many components similar to electrolysis propulsion systems. Recent advances in component technology include: lightweight tankage, water vapor feed electrolysis, fuel cell...

GRO J174428 is the first known Xray source to display bursts, periodic pulsations, and quasiperiodic oscillations. This source may thus provide crucial clues that will lead to an understanding of the differences in the nature of the Xray variability from various accreting neutron stars. The orbital period is 11.8 days, and the measured mass function of 1.31 x 10(exp 4) solar mass is one of the smallest among all known binaries. If we assume that the donor star is a lowmass giant...

The daily variation of the solar photocenter over some 11 years is derived from the Mount Wilson data reprocessed by Ulrich et al. 2010 to closely match the surface distribution of solar irradiance. The standard deviations of astrometric jitter are 0.52 microAU and 0.39 microAU in the equatorial and the axial dimensions, respectively. The overall dispersion is strongly correlated with the solar cycle, reaching 0.91 microAU at the maximum activity in 2000. The largest shortterm deviations from...

Pulse shaping of periodic relativistic electron pulses generates patterns of Cerenkov radiation distinctive of the distribution of charge within a bunch. Computer simulation mapped the radiation pattern of the level, triangular, trapezoidal, rounded, Gaussian, level plus sinusoidal ripple, and multiple hump charge distributions. Each shape, with exception of the level plus sinusoidal ripple, generates a series of radiation patterns unique to that shape. This research provides a basis for...

Data collected in the 1960's and recent data indicate that the flow in the Strait of Gibraltar does not move in the form of continuous currents but as tidalinduced pulses. A descriptive model based on these data indicates that the pulses are a result of increases in the speed of the tidal streams as they encounter the constrictions of the regional bathymetry (especially the Camarinal Sill and between the Camarinal Sill and Tarifa). Periodic increases modify the regional flow so that during...

A general analysis of periodic threedimensional vortical disturbances of streaming motions around streamlined and bluff bodies is developed using a unified approach wherein the mathematical problem is reduced to solving a single inhomogeneous wave equation with nonconstant coefficients. In the limit of vanishing Mach number, the problem is formulated in terms of an inhomogeneous Fredholm integral equation of the second kind. The analysis is first applied to study the unsteady aerodynamics of...

This thesis presents a model which simulates the scattering from a fluid loaded Ibeam and the resultant behavior due to fluidstructure interaction. Chapter I gives an overview of the problem and describes the characteristics of the solid and fluid, the aspects of periodicity, boundary conditions and the coupling of the two media. The governing equations of motion are scaled in Chapter II. In Chapter III, the finite difference formulae for these equations are derived, as is the nonlocal...

The solar oscillation with period near 160 minutes is found to be unique in a spectrum computed over the range of periods from about 71 to 278 minutes. A best estimate of the period is 160.0095 + or  0.001 minutes, which is different from 160 minutes (one ninth of a day) by a highly significant amount. The width of the peak is approximately equal to the limiting resolution that can be obtained from an observation lasting 6 years, which suggests that the damping time of the oscillations is...

The delta 14C values in 42 rings of a white spruce grown in Mackenzie Delta was measured as a continuing effort of tracing the history of solar modulation of cosmic ray intensity. The delta 14C values in six rings were measured, in search of a 14C increase due to two large solar flares that occurred in 1942. The results are presented.

These four points summarize our work to date. (1) Conciliation of solar and stellar photometric variability. Previous research by us and colleagues suggested that the Sun might at present be showing unusually low photometric variability compared to other sunlike stars. Those early results would question the suitability of the technique of using sunlike stars as proxies for solar irradiance change on time scales of decades to centuries. However, our results indicate the contrary: the Sun's...

The behavior of pulsation in the outer layers of a typical Mira variable was studied in the adiabatic and isothermal limits. A shock wave propagates outward once per period and the radial velocity obtained from observations of hydrogen emission lines is identified with the velocity of gas in the post shock region. In the adiabatic case, mass loss in the form of a steady stellar wind was produced. In the isothermal case, no continuous mass loss was produced but occasional ejection of shells...

Lattice booms and platforms composed of flexible members or large diameter rings which may be stiffened by cables in order to support membranelike antennas or reflector surfaces are the main components of some large space structures. The nature of these structures, repetitive geometry with few different members, makes possible relatively simple solutions for buckling and vibration of a certain class of these structures. Each member is represented by a stiffness matrix derived from the exact...

The coherent properties of six oscillations over a two week period in which seven days of equatorial diameter measurements were analyzed, are confirmed by the addition of an extra day of data. The two large 1 (the principal order number in the spherical harmonic expansion of the eigenfunction) gmode oscillations may be candidates for the slowly rotating mode locked structures. For the four low frequency pmodes, periodic nature is observed in the daily power levels, varying with periods of...

The generation and amplification of vortices by surface inhomogeneities, both in the form of surface waviness and of wallnormal velocity, is investigated using the nonlinear PSE equations. Transients and issues of algebraic growth are avoided through the use of a similarity solution as initial condition for the vortex. In the absence of curvature, the vortex decays as the square root of 1/x when flowing over streamwise aligned riblets of constant height, and grows as the square root of x when...

The cyclic variation of solar activity is both irregular and intermittent. We have sought to isolate and illuminate the physical mechanisms of this behavior and to provide a mathematical description of it. Our work has brought out three ingredients of the solar cycle that we believe to be central to its operation. (1) The seat of the solar cycle is in a shear layer just below the solar convection zone. We have investigated the structure of this layer (which we call the solar tachocline) in some...

It has been shown both theoretically and experimentally that it is possible to control the symbolic dynamics of a chaotic system using small perturbations. We show a method of very rapidly targeting a region of width e near a desired state point on a onedimensional map using control of symbolic dynamics; this method demonstrates that controlling symbolic dynamics provides an efficient algorithm for targeting.

This thesis studies the U.S. maritime labor force as it affects the manning of the Ready Reserve Force (RRF). The focus is on the reasons for periodic variations in the labor supply within the U.S. maritime industry. The amount of labor that will be needed to man a fullyactivated RRF is compared with the amount of labor predicted to be available to the RRF and the commercial world. The RRF will require about 16 percent of the predicted available labor force. Shortages are bound to occur,...

Based on a 27 year data record from the COADS and SEIC data sets, a statistical analysis of ice concentration, sea surface temperature (SST), air temperature, U and V wind components, and sea level pressure anomaly data was conducted for five locations in the icecovered waters of the North Atlantic. Spectral densities and autocorrelations of the time series for each variable were calculated to establish a measure of persistence and periodicity. Regression equations were formulated based on the...

The importance of including the effects of local line perturbations (such as a cable clamp) is discussed in terms of the reflection coefficient presented to waves on the transmission line, and general curves for determining when to neglect such effects are given. Next, the behavior of a finite length transmission line with periodic loading is investigated and...

In 1929, Sir R. A. Fisher proposed a test for periodicity in a time series based on the maximum spectrogram ordinate. This paper proposes a oneparameter family of tests that contains Fisher's test as a special case. It is shown how to select from this family a test that will have substantially larger power than Fisher's test against many alternatives, yet will lose only negligible power against alternatives for which Fisher's test is known to be optimal. Critical values are calculated and...

A channel with a rectangular crosssection, 40 to 1 aspect ration (height is 0.0127 m), and 4.27 m test section (336 channel heights) is used to study the effects of imposed pulsations on transitional flow phenomena. Periodic velocity variations are produced in the test section using a single rotating vane located in the flow downstream of the test section. Flows with Reynolds numbers (Re) ranging from 1100 to 3600 are studied at Stokes numbers of 4.08 and 5.79 and Strouhal numbers from 0.02 to...

A compilation of records of the aurora observed in China from the Time of the Legends (2000  3000 B.C.) to the mid18th century has been used to infer the frequencies and strengths of solar activity prior to modern times. A merging of this analysis with auroral and solar activity patterns during the last 200 years provides basically continuous information about solar activity during the last 2000 years. The results show periodicities in solar activity that contain average components with a...

In modeling the solar cycle, one proceeds on the assumption that the processes driving the solar cycle are deterministic. In that case, a chaotic model is a good choice for a description of its complexity. In the modeling reported here, the authors suppose that the solar activity variation is composed of two distinct, coupled processes: one a conventionally chaotic system, and the other a nonlinear oscillator. This idea comes directly from their analysis of the observations. Since the sun's...

We consider kinematic chains evolving on a finitedimensional Lie group C under nonholonomic constraints, where snakelike global motion is induced by shape variations of the system. In particular, we consider the case when the evolution of the system is restricted to a subspace h of the corresponding Lie algebra g, where h is not a subalgebra of g and it can generate the whole algebra under Lie bracketing. Such systems are referred to as Csnakes. Away from certain singular configurations of...

These responses will likely affect the use of arctic shelves by marine mammals. Our study is applying a variety of recently developed technologies in a...

It was found that viscous effects and flow separation need to be included for accurate simulations in steady flow. Unsteady aspects are far more important and critical for...

Linear frequencystepped pulse trains, periodic in both time and frequency, have ambiguity functions which are periodic in both delay and doppler. One way of suppressing these ambiguities or grating lobes is time and frequency staggering of subpulses in the train, smearing out the grating lobes into a delay/doppler residue level. However this works well only with a large number of subpulses and a small pulse train duty factor. Another approach, described here, is to chirp code each subpulse,...

A Fourier representation of the perturbation effects of the moon's eccentricity on a satellite in orbit about L3 was constructed and verified numerically. It was then incorporated in a modal control scheme for linear systems that are time periodic which was developed by Shelton. The feasibility of this modified control scheme was then verified by computer simulation by controlling the actual nonlinear motions of the satellite with the modified controller. (Author)
