Turbulent Exchange Coefficients For Sensible Heat And Water Vapor Under Advective Conditions, Shashi Verma, Norman J. Rosenberg, Blaine L. Blad

School of Natural Resources: Faculty Publications

Results are presented of micrometeorological measurements made over alfalfa and soybeans under conditions of sensible heat advection at Mead, Neb. The sensible heat advection phenomenon reported here is of a regional rather than a local nature. The exchange coefficient for sensible heat (Kh) is found to be generally greater than the exchange coefficient for water vapor (Kw). This result contradicts the usaul assumption of equality of Kh and Kw under nonadvection (lapse or unstable) conditions when the net transfer of both sensible heat and water vapor are away from the earth's surface. Under advective conditions, however, heat and water vapor …

Extreme Evapotranspiration By Irrigated Alfalfa: A Consequence Of The 1976 Midwestern Drought, Norman J. Rosenberg, Shashi Verma

School of Natural Resources: Faculty Publications

The rate of evapotranspiration by irrigated alfalfa at Mead, NE (41°09'N; 96°30'W, elevation 354 m) reached record levels in 1976. Evapotranspiration was measured with precision weighing lysimeters in a field 1.9 ha in size. Evapotranspiration ranged during the growing season from 4.75 to 14.22 mm day^–1 and exceeded 10 mm day­^–1 on one-third of the days studied. On each day of study the ratio of latent heat flux density (LE) to the sum of the net radiation and soil heat flux densities (Rn+S) was such that LE/ (Rn+S) > 1, indicating the occurrence of significant sensible heat advection. On …

Calculations Of Ion‐Ion Recombination Rates At High Pressures, J. M. Wadehra, J. N. Bardsley

Physics and Astronomy Faculty Research Publications

The classical theory of ion‐ion recombination in gases of high density is extended to allow for arbitrary ratios of the masses of the three species involved. Calculations are performed for the recombination of Ar+, Ar+ 2, Kr+, and Kr+ 2 ions with F− and of Hg+ and Ar+ with Cl− in an argon gas. The effective two‐body rates peak between 2×10−6 and 3×10−6 cm3 sec−1 at pressures above 1 atm.

Admissible Solutions Of Finite State Sequence Compound Decision Problems, Stephen B. Vardeman

Stephen B. Vardeman

A general method of constructing procedures which are both admissible and asymptotically optimal in finite state sequence compound decision problems is suggested and applied to the situation of a two state classification component. When used in an empirical Bayes setting, procedures so constructed are seen to be both admissible and asymptotically optimal.

Excited States And Photochemistry Of Saturated Molecules. Ix. Vertical Excited States Of Silane, Mark S. Gordon

Mark S. Gordon

The vertical excited states of silane are investigated using ten different basis sets to systematically compare the effects of (a) Rydberg functions, (b) diffuse d functions, (c) valence d functions, and (d) a split valence shell. Wavefunctions are generated using all singly excited configurations, excluding inner shells. The low‐lying singlet states are dominated by excitations into the diffuse orbitals, while low‐lying triplets have significant valence character. Valence d functions have a minor effect on excitation energies if an adequate valence s p basis set is used. The main effect of Rydbergd functions is to introduce additional Rydberg states below the …

Recent Climatic Fluctuations Of The Canadian High Arctic And Their Significance For Glaciology, Raymond S. Bradley, John England

Raymond S Bradley

Various measures of the character of ablation season conditions in the Canadian High Arctic (north of 74°N) are discussed based on an analysis of daily climatic data from Alert, Eureka, Isachsen, Resolute, and Thule. Melting degree day totals appear to be the most useful index of "summer warmth." An abrupt change in the summer climate of the region occurred around 1963164. Various indices indicate a marked decrease in summer temperature after 1963. During the same period, annual precipitation in the north and northwest has increased. Glacier mass balance is strongly controlled by summer climate; in particular, annual melting degree day …

Former Ice Shelves In The Canadian High Arctic, John England, Raymond S. Bradley, G. H. Miller

Raymond S Bradley

ABSTRACT. Moraines deposited by the outermost ice advance across Judge Daly Promontory, northeastern Ellesmere Island, reflect thin, topographically controlled ice lobes extending to sea-level. The termini of two ice lobes were investigated and both produced ice shelves where they flowed into isostatically depressed embayments along western Kennedy Channel. Morphological evidence for these ice shelves occurs at the entrance to these valleys where steeply descending lateral moraines become abruptly horizontal for 2 km. In addition, both the horizontal moraines and associated pro-glacial terraces are fossiliferous downvalley from the apparent grounding line. Based on the differences in elevation between the horizontal moraines …

Direct Observation Of Pulsed Third Sound Mass Displacement Waves In Unsaturated Superfluid 4he Films, Robert Hallock, J. S. Brooks, F. M. Ellis

Robert Hallock

We report direct observation of pulsed third-sound film thickness oscillations in unsaturated superfluid 4He films using a capacitance technique. Simultaneous measurements of accompanying temperature oscillations allow the first study of the relative amplitudes of these oscillations and the results are in reasonable agreement with the theory of Bergman although some discrepancies are noted.

The Stratigraphy And Structure Of The Columbia River Basalt In The Clackamas River Drainage, James Lee Anderson

Dissertations and Theses

The Clackamas River drainage within the western Cascade Range is approximately aligned with a northwest trending lineation defined by the Portland Hills and the Brothers Fault zone. This area is occupied by an extensive Columbia River Basalt sequence that is deeply incised by the Clackamas River and its tributaries. Two major basalt units of the Yakima Basalt Subgroup, including the Grande Ronde Basalt and the Frenchman Springs Member of the Wanapurn Basalt, are distinguishable in a 515 meter to 550 meter accumulation. Of particular interest is the presence of five trending right-lateral strike-slip faults is consistent with a stress model …

Dissertations and Theses

Sediments in the South Slough Estuarine Sanctuary, Coos Bay, Oregon, were sampled and studied in order to determine the sources, dispersal systems and depositional facies of sedimentation. The purpose of the study was to establish baseline measurements and observations on the existing sediment conditions within the relatively undisturbed South Slough Estuarine Sanctuary

A Technique To Calculate Complex Electromagnetic Fields By Using The Finite Element Method, Davood Asgharian

Dissertations and Theses

A computer program based on Maxwell's equations is developed to calculate two-dimensional complex potentials by the Finite Element Method. This study offers a solution to a complex continuum problem by allowing a subdivision into a series of simple interrelated problems. The region of interest is divided into triangular elements. For each node in the grid, the Finite Element Method is used to set up an equation for the potential as a function of those of the surrounding nodes. All these equations are solved by the Gaussian Elimination Method. For increased accuracy this method requires a high degree of division of …

Thermodynamics And Statistical Mechanics Of The Ideally Polarisable Electrode Gibbs Isotherm And Surface Tension, Jean-Pierre Badiali, Jerry Goodisman

Chemistry - All Scholarship

A definition of the ideally polarisable electrode which allows a general statistical mechanical treatment is given, comparisons with the usual thermodynamic approach being made. It is shown that, with this definition, the system behaves as a pure capacitance to an imposed alternating potential of sufficiently low frequency. The equilibrium states of the system are described by the grand canonical distribution. Thermodynamic functions, given in terms of the grand canonical partition function, can be computed in molecular terms: In particular, general expressions for the surface tension and the pressure are obtained, and compared to those proposed by various authors. The separation …

Estimation Of Μy Using The General Regression Model (In Sampling), Michael R. Manieri

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The methods of ratio and regression estimators discussed by Cochran(l977) are given as background materials and extended to the estimation of µy, the population mean of the Y's, using a general regression model.

The propagation of error technique given by Deming(l948) is used as an approximation to find the variance of the estimator µy.

Examples are given for each of the various models. Variances of μy are calculated and compared

Factor Analysis Method, Stephen Hauwah Kan

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The logical steps performed when doing a factor analysis can be classified into three operation s. The first step concerns the exact mode of analysis and involves the type of centering, scaling and formation o f sums of squares . The second step involves extraction of initial factors. The algebraic basis of the factors are rotated in the last step to obtain a more easily interpreted set of factors. At each step several different methods have been suggested and appear in the literature. Two primary modes of factor analysis are commonly used an d they are denoted as R-mode and …

Optimal Design Of A Quasi-Redundant Protective System For Nuclear Reactors, J. M. Kontoleon

Faculty of Informatics - Papers (Archive)

In many instances protective systems used in nuclear reactors are quasi-redundant systems; each of a number of safety channels feeds a number of independent protective units. A reactor shutdown is initiated if more than a specified number of units are in favour of shut down. The objective is to achieve a very high reliability at a reasonable cost. An analysis is presented to obtain the reliability, failsafe and fail-danger probabilities of a quasi-redundant system. Three algorithms are given for: (a) the design of a quasi-redundant system having the maximum reliability subject to a cost constraint, (b) the optimal design satisfying …
