OLAP Services

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Sanghvi, Rajendra
Description: On-line Analytical Processing (OLAP) is a very interesting platform to provide analytical power to the data present in the database. This paper discusses the system designed which handles integration of data from two remote legacy reservation systems to merge as one Integrated database server and also the design of an OLAP database and building an OLAP cube for the data warehousing. OLAP cube is useful for analysis of data and also for making various business decisions. The Data Transformation Services (DTS) in the Microsoft® SQL Server 2000 is used to integrate as a package the collection of data and also for refreshing data in the databases. On-line Analytical Processing (OLAP) cube is designed using Microsoft® Analysis Server.

Older Workers: Disability And Employment

Older Workers: Disability And Employment

Date: December 2011
Creator: Litle, Melanie A.
Description: The purpose of this study was to explore the demographic variables, typical vocational services, and competitive employment rates of older workers, ages 40 - 69 years of age, with disabilities using the RSA-911 database. The results describe the types of services received and the competitive employment outcomes for state and federal vocational rehabilitation consumers receiving services in 2009. Furthermore the sample of older workers (N = 1,152) was equally stratified into three age groups. Older workers, aged 60 to 69, had higher levels of education, received more types of vocational services, and were competitively employed at a much higher rate than those in the other age groups. The methods, discussion, study limitations, and recommendations for future research are presented.

Oligonucleotide guanosine conjugated to gallium nitride nano-structures for photonics.

Oligonucleotide guanosine conjugated to gallium nitride nano-structures for photonics.

Date: August 2008
Creator: Li, Jianyou
Description: In this work, I studied the hybrid system based on self-assembled guanosine crystal (SAGC) conjugated to wide-bandgap semiconductor gallium nitride (GaN). Guanosine is one of the four bases of DNA and has the lowest oxidation energy, which favors carrier transport. It also has large dipole moment. Guanosine molecules self-assemble to ribbon-like structure in confined space. GaN surface can have positive or negative polarity depending on whether the surface is Ga- or N-terminated. I studied SAGC in confined space between two electrodes. The current-voltage characteristics can be explained very well with the theory of metal-semiconductor-metal (MSM) structure. I-V curves also show strong rectification effect, which can be explained by the intrinsic polarization along the axis of ribbon-like structure of SAGC. GaN substrate property influences the properties of SAGC. So SAGC has semiconductor properties within the confined space up to 458nm. When the gap distance gets up to 484nm, the structure with guanosine shows resistance characteristics. The photocurrent measurements show that the bandgap of SAGC is about 3.3-3.4eV and affected by substrate properties. The MSM structure based on SAGC can be used as photodetector in UV region. Then I show that the periodic structure based on GaN and SAGC can have photonic ...

On Bounded Variation

On Bounded Variation

Date: August 1966
Creator: Lewis, Paul Weldon
Description: This paper is primarily concerned with developing the theory of real-valued functions of bounded variation and those ideas which are closely related to this main topic. In addition to this, some emphasis has been placed on the relationship of the theory of functions of bounded variation to specific areas of analysis. In particular, integration theory has been chosen as the vehicle to demonstrate this connection.

On Continuity of Functions Defined on Unrestricted Point Sets

On Continuity of Functions Defined on Unrestricted Point Sets

Date: August 1958
Creator: Wilson, Ural
Description: This thesis is concerned with an investigation of the generalizations of continuous real functions of a real variable. In particular, the relationship between uniform continuity and ordinary continuity is concerned. The concept of uniform continuity was first introduced by Heine about 1900.

On Lane's Integral

On Lane's Integral

Date: August 1971
Creator: Hill, William James
Description: The problem and purpose of this paper is to develop Lane's Integral in two-space, and then to expand these concepts into three-space and n-space. Lane's Integral can be used by both mathematicians and statisticians as one of the tools in the calculation of certain probabilities and expectations. The method of presentation is straightforward with the basic concepts of integration theory and Stieltjes Integral assumed.

On Objects and Affections: Contemporary Representations of the Gay Man/Straight Woman Dyad in Popular Film and Television

On Objects and Affections: Contemporary Representations of the Gay Man/Straight Woman Dyad in Popular Film and Television

Date: December 2000
Creator: Pillion, Owen L.
Description: This project explores the representational strategies used to depict a gay male/straight female dyad across a variety of popular media. The study problematizes and critically evaluates how the narrativization of the dyad both challenges and reinforces stereotypes of gay men and at the same time circulates a troubling image of femininity in the figure of the straight woman. This line of argument is extended to the context of "Lifestyle Television" to demonstrate how the dyad implicitly structures two particular programs. It is suggested that the prevalence of the dyad is in part indicative of an assimilation of a particular gay identity into mainstream culture. The ideological implications of the dyad are discussed throughout this thesis.

On-Road Remote Sensing of Motor Vehicle Emissions: Associations between Exhaust Pollutant Levels and Vehicle Parameters for Arizona, California, Colorado, Illinois, Texas, and Utah

On-Road Remote Sensing of Motor Vehicle Emissions: Associations between Exhaust Pollutant Levels and Vehicle Parameters for Arizona, California, Colorado, Illinois, Texas, and Utah

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Dohanich, Francis Albert
Description: On-road remote sensing has the ability to operate in real-time, and under real world conditions, making it an ideal candidate for detecting gross polluters on major freeways and thoroughfares. In this study, remote sensing was employed to detect carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxide (NO). On-road remote sensing data taken from measurements performed in six states, (Arizona, California, Colorado, Illinois, Texas, and Utah) were cleaned and analyzed. Data mining and exploration were first undertaken in order to search for relationships among variables such as make, year, engine type, vehicle weight, and location. Descriptive statistics were obtained for the three pollutants of interest. The data were found to have non-normal distributions. Applied transformations were ineffective, and nonparametric tests were applied. Due to the extremely large sample size of the dataset (508,617 records), nonparametric tests resulted in "p" values that demonstrated "significance." The general linear model was selected due to its ability to handle data with non-normal distributions. The general linear model was run on each pollutant with output producing descriptive statistics, profile plots, between-subjects effects, and estimated marginal means. Due to insufficient data within certain cells, results were not obtained for gross vehicle weight and engine type. The "year" ...
