• #### Comparison of analytical and numerical biodegradation models with application to aquifer remediation ﻿

(1989)
Contaminant transport in ground water is predicted through the use of analytical and numerical models. The horizontal plane source analytical code (HPS) was compared to the USGS solute transport numerical code (MOC) for ...
• #### Comparison of clusters with and without detectable Wolf-Rayet stars in starburst galaxies using optical, near-infrared imagery and spectroscopy ﻿

(2003)
This optical, near-infrared observational study compares the properties of clusters with and without Wolf-Rayet (W-R) stars in starburst galaxies. Previous studies looked only at the galactic properties. Because this work ...

(1966)
• #### Comparison of estimates of airmass aging using particle and other measurements near Fort Worth, TX ﻿

(2013-06-05)
The composition, concentration, and size of submicron aerosols were measured with a time resolution of five minutes by an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) at a rural location ...
• #### Comparison of gradient-restoration algorithms for optimal control problems with nondifferential constraints and general boundary conditions ﻿

(1994)
The problem considered here involves a functional I subject to differential constraints, nondifferential constraints, and general boundary conditions. It consists of finding the state x(t), control u(t), and parameter $\pi$ ...
• #### Comparison of Guidance Methods for Autonomous Planetary Lander ﻿

(2011)
Guidance methods for a powered descent planetary lander are examined. Several guidance laws are developed and analyzed including Apollo derived, modified Apollo, time efficient and fuel efficient methods. These laws are ...
• #### Comparison of laser-produced plasma target materials for pumping the 109 nm xenon(2+) Auger laser ﻿

(1995)
Short wavelength lasers have many potential applications in scientific and engineering fields. The goal of this research was to improve the output energy of the Xe$\sp{2+}$ 109 nm laser. We compared cadmium, copper, gold, ...

(1974)
• #### Comparison of the abilities of historical and current cost information to predict funds flows ﻿

(1991)
This study compared current operating income (COI), current operating income plus realizable holding gains measured in constant dollars and purchasing power gain (i.e., current real income (CRI)), and historical cost income ...
• #### COMPARISON OF TWO NOVEL LIST SPHERE DETECTOR ALGORITHMS FOR MIMO-OFDM SYSTEMS ﻿

(2006-09-01)
In this paper, the complexity and performance of two novel list sphere detector (LSD) algorithms are studied and evaluated in multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) system. ...
• #### Comparison study of ring current simulations with and without bubble injections ﻿

(2016)
For many years, stand-alone ring current models have been successfully producing storm time ring current enhancements without specifying explicit localized transient injections along their outer boundaries. However, both ...
• #### A Comparison The College System ﻿

(1963-09-18)
• #### Comparisons of approximate bases for hydrogen in a magnetic field ﻿

(1983)
Solutions to the diamagnetic Hamiltonian for Rydberg states of hydrogen are studied in the low-magnetic-field regime where term mixing can be ignored. Several recently proposed approximate bases are compared by calculating ...

• #### Compete This Summer Sailors to Organize ﻿

(1965-04-22)
• #### Competence to consent ﻿

(1989)
Informed consent is valid only if the person giving it is competent. Although allegedly informed consents are routinely tendered, there are nonetheless serious problems with the concept of competence as it stands. First, ...
• #### Competing mechanisms and scaling laws for carbon nanotube scission by ultrasonication ﻿

(2012)
Dispersion of carbon nanotubes (CNTs) into liquids typically requires ultrasonication to exfoliate individuals CNTs from bundles. Experiments show that CNT length drops with sonication time (or energy) as a power law t?m. ...
• #### Competition and efficiency in the European airline industry, 1976-1990 ﻿

(1994)
The European Economic Community has "opened the European skies" with its liberalization plan for the airline industry. This plan will expose the heavily protected European airlines to a competitive environment. The cost ...
• #### Competition and inhibition in lexical retrieval: Are common mechanisms used in language and memory tasks? ﻿

(2007)
The following series of experiments examined whether common mechanisms are involved in word retrieval within language and memory domains. Four patients with short-term memory (STM) deficits were examined; however, two of ...
