Vessel Traffic Systems, William D. Lynch
Vessel Traffic Systems, William D. Lynch
Marine Affairs Theses and Major Papers
This paper will examine the historical impetus for Vessel Traffic System (VTS) development in the United States. Cost benefit techniques utilized to establish the VTS requirements are discussed and the data base upon which the analysis is conducted is critiqued. General Accounting Office criticism of the Coast Guard's VTS development process are analyzed. Finally VTS is examined as a single component in the improvement of port logistics, which must be arrayed against other alternatives to make the most effective use of scarce resources. This final element is discussed with respect to the Federal government's attempt to recover clearly allocatable costs …
The Exploitation Of The Antarctic Oil And Its Environmental And Legal Implications, Renzo Follegati
The Exploitation Of The Antarctic Oil And Its Environmental And Legal Implications, Renzo Follegati
Marine Affairs Theses and Major Papers
The focus of the paper is the feasible exploitation of the Antarctic offshore oil and the environmental consequences that this fact could have to the whole ecosystem of the Southern Ocean and for other ecosystems of neighboring regions, e.g. the South East Pacific basin. The legal implications that have to do with the exploitation of the Antarctic oil and the regulations that could be applied to preserve the environment are examined.
A Preliminary Investigation Of The Lithological Characteristics Of The Troutdale Formation In Portions Of The Camas, Sandy, Washougal, And Bridal Veil Quadrangles, David Lee Cole
Dissertations and Theses
The study area encompasses a region of about 80 square kilometers, centered about Corbett, Oregon. Sieve analyses suggest that the Troutdale Formation is composed of a conglomerate, a coarse-grained sandstone, and a siltstone lithofacies. Measured sections data show that 56 to 60 percent of the Troutdale Formation's exposures are composed of the conglomerate lithofacies. The coarsegrained sandstone lithofacies makes up 34 to 38 percent, while the siltstone lithofacies makes up only 4 to 8 percent. Pebble count data show that the representation of basalt varies from 69 to 100 percent, with an average of 85 percent, while quartzite varies from …

Ionospheric Hot Spot At High Latitudes, Robert W. Schunk, Jan Josef Sojka
Ionospheric Hot Spot At High Latitudes, Robert W. Schunk, Jan Josef Sojka
All Physics Faculty Publications
A hot spot (or spots) can occur in the high‐latitude ionsophere depending on the plasma convection pattern. The hot spot corresponds to a small magnetic local time‐magnetic latitude region of elevated ion temperatures located near the dusk and/or dawn meridians. For asymmetric convection electric field patterns, with enhanced flow in either the dusk or dawn sector of the polar cap, a single hot spot should occur in association with the strong convection cell. However, on geomagnetically disturbed days, two strong convection cells can occur, and hence, two hot spots should exist. The hot spot should be detectable when the electric …

Ion Temperature Variations In The Daytime High-Latitude F Region, Robert W. Schunk, Jan Josef Sojka
Ion Temperature Variations In The Daytime High-Latitude F Region, Robert W. Schunk, Jan Josef Sojka
All Physics Faculty Publications
We improved our high-latitude ionospheric model by including thermal conduction and diffusion-thermal heat flow terms in the ion energy equation so that we could study the ion temperature variations in the daytime high-latitude F layer in a region poleward of the auroral oval for steady state conditions at local noon. From our study we found that (1) The variation of Ti with solar cycle, season, and geomagnetic activity closely follows the Tn variation. The general trend is for higher temperatures in summer than in winter, at solar maximum than at solar minimum, and for active magnetic conditions than for quiet …
Interactions Of Northern Fur Seals And Commercial Fisheries, Charles W. Fowler
Interactions Of Northern Fur Seals And Commercial Fisheries, Charles W. Fowler
United States Department of Commerce: Staff Publications
Under international agreement, the northern fur seal (Callorhinus ursinus) is managed with the objective of obtaining a maximum sustainable yield. Currently the harvest is restricted to subadult males; however, between 1956 and 1968 the fur seal population of the Pribilof Islands was subjected to a harvest of females. This harvest was justified, in part, as an attempt to stimulate the production of greater quantities of harvestable animals (Chapman 1981). A reduction in the population occurred during this period as can be seen in Figure 1. As described in York and Hartley (1981), the female harvest itself provides an …

Unbounded Functions And Positive Linear-Operators, J. J. Swetits, B. Wood
Mathematics & Statistics Faculty Publications
The approximation of unbounded functions by positive linear operators under multiplier enlargement is investigated. It is shown that a very wide class of positive linear operators can be used to approximate functions with arbitrary growth on the real line. Estimates are given in terms of the usual quantities which appear in the Shisha-Mond theorem. Examples are provided.

Probabilistic Simulations, Nicholas J. Pippenger
Probabilistic Simulations, Nicholas J. Pippenger
All HMC Faculty Publications and Research
The results of this paper concern the question of how fast machines with one type of storage media can simulate machines with a different type of storage media. Most work on this question has focused on the question of how fast one deterministic machine can simulate another. In this paper we shall look at the question of how fast a probabilistic machine can simulate another. This approach should be of interest in its own right, in view of the great attention that probabilistic algorithms have recently attracted.
Rearrangeable Networks With Limited Depth, Nicholas Pippenger, Andrew C.-C. Yao
Rearrangeable Networks With Limited Depth, Nicholas Pippenger, Andrew C.-C. Yao
All HMC Faculty Publications and Research
Rearrangeable networks are switching systems capable of establishing simultaneous independent communication paths in accordance with any one-to-one correspondence between their n inputs and n outputs. Classical results show that Ω( n log n ) switches are necessary and that O( n log n ) switches are sufficient for such networks. We are interested in the minimum possible number of switches in rearrangeable networks in which the depth (the length of the longest path from an input to an output) is at most k, where k is fixed as n increases. We show that Ω( n1 + 1/k ) switches …
Atomic Carbon In The Atmosphere Of Venus, Jane L. Fox
Atomic Carbon In The Atmosphere Of Venus, Jane L. Fox
Physics Faculty Publications
The densities of atomic carbon in the Venusian thermosphere are computed for a model which includes both chemistry and transport. The maximum density of C is 2.8×107 cm−3 near 150 km for an assumed O2 mixing ratio of 1×10−4. Photoionization of atomic carbon is found to be the major source of C+ above 200 km, and resonance scattering of sunlight by atomic carbon may be the major source of the C I emissions at 1561 Å, 1657 Å, and 1931 Å. The computed C+ densities are found to be in substantial agreement with …

Culture Of Channel Catfish In East-Central South Dakota Dugout Ponds, Martin Nicholas Dilauro
Culture Of Channel Catfish In East-Central South Dakota Dugout Ponds, Martin Nicholas Dilauro
Electronic Theses and Dissertations
Twenty dugout ponds in east-central South Dakota were stocked 10 May 1980 with fingerling (mean weight 39.4 g, mean total length 108.4 mm) channel catfish (Ictalurus punctatus) at stocking rates of 309, 618, 1,235, and 1,853 fish/ha. Supplemental food was provided in 16 ponds (four at each stocking rate) at a rate of 4% body weight every other day. Fish in four ponds stocked, one at each of the respective stocking rates were not fed. Eleven of the 16 ponds which received feed were considered fit for analysis at the end of the study period, 27 September 1980. Two of …

In Situ Study Of The Physical Mechanisms Controlling Induced Seismicity At Monticello Reservoir, South Carolina, Mark D. Zoback, Stephen Hickman
In Situ Study Of The Physical Mechanisms Controlling Induced Seismicity At Monticello Reservoir, South Carolina, Mark D. Zoback, Stephen Hickman
United States Geological Survey: Staff Publications
In two ~1.1-km-deep wells, the magnitudes of the principal in situ stresses, pore pressure, permeability, and the distribution of faults, fractures, and joints were measured directly in the hypocentral zones of earthquakes induced by impoundment of Monticello Reservoir, South Carolina. Analysis of these data suggests that the earthquakes were caused by an increase in subsurface pore pressure sufficiently large to trigger reverse-type fault motion on preexisting fault planes in a zone of relatively large shear stresses near the surface. The measurements indicated (1) near-critical stress differences for reverse-type fault motion at depths less than 200-300 m, (2) possibly increased pore …
Permeability, Underpressures, And Convection In The Oceanic Crust Near The Costa Rica Rift, Eastern Equatorial Pacific, Roger N. Anderson, Mark D. Zoback
Permeability, Underpressures, And Convection In The Oceanic Crust Near The Costa Rica Rift, Eastern Equatorial Pacific, Roger N. Anderson, Mark D. Zoback
United States Geological Survey: Staff Publications
In situ permeability and pore pressures were measured 200 m deep beneath the top of the oceanic crust at DSDP site 504B. These measurements have relevance for the transition from convective to conductive heat flow on the south flank of the Costa Rica Rift. Conventional 'slug' and constant rate injection tests were made below a hydraulic packer set at various depths in the hole. The packer was first set in a massive flow unit 37 m below the sediment-basement interface. The bulk permeability of the 172.5m of pillow basalts and basaltic flows below the packer was found to be about …

A Study Of The Critical Cluster Size For Water Monolayer Clusters On A Model Agi Basal Substrate, Richard C. Ward, Barbara N. Hale, Sergio Terrazas
Physics Faculty Research & Creative Works
We present a formalism and estimate a critical cluster size for water monolayer formation on a (rigid) model AgI basal substrate. The formalism is modified from that developed for vapor clusters [B. N. Hale and R. C. Ward, J. Stat. Phys. 28, 487 (1982)] and uses a Metropolis Monte Carlo method developed by Squire and Hoover [J. Chem. Phys. 50, 701 (1969)] to determine (Helmholtz) free energy differences for clusters containing n and n-1 molecules. Calculations for clusters of n=1, 2, 3, 4, 6, and 24 water molecules on a model AgI basal face at 265 K are …

The authors discuss the expansion cloud chamber system known as the University of Missouri-Rolla-absolute Aitken nucleus counter. A review of the properties of an expansion chamber and how it creates a supersaturation are given and a critical examination is made of the assumptions in its operation, e.g. adiabaticity of the expansion. The design of the chamber is described in detail and an analysis of the propagation of errors is given for quantities measured and calculated. A short review of the performance of the chamber and some general comments relative to comparisons with other Aitken nucleus counting instruments are given. The …
Electron-Capture Collisions Of H+ With Ground- And Excited-State Na, M. Kimura, Ronald E. Olson, J. Pascale
Electron-Capture Collisions Of H+ With Ground- And Excited-State Na, M. Kimura, Ronald E. Olson, J. Pascale
Physics Faculty Research & Creative Works
Pseudopotential molecular-structure calculations have been used to obtain the low-lying interaction energies for NaH+. The wave functions were used to calculate accurate radial and rotational coupling matrix elements. Scattering calculations which include electron translational factors were performed using up to eight coupled channels for laboratory energies 0.1 to 10 keV. Electron capture from ground-state Na 3s yields cross sections in the 10-15-cm2 range of which the dominant products are H 2s and H 2p. Electron capture from excited Na 3p does not show an enhanced cross section relative to capture from the ground state even though the energy gap E(R=) …
