RDBMS AND XML FOR TELEMETRY ATTRIBUTES

Steele, Doug 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / One problem facing telemetry engineers is the ability to easily translate telemetry attributes from one system to another. Engineers must develop a written set of attributes that define a given telemetry stream and specify how the telemetry stream is to be transmitted, received, and processed. Telemetry engineers take this document and create the configuration for each product that will be exposed to the telemetry stream (airborne, ground, flight line). This process is time-consuming and prone to error. L-3 Telemetry-West chose to implement a solution using relational databases and eXtensible Markup Language (XML) to solve this and other issues.

Texas school board president's perspective on attributes of hispanic male superintendent

Cervantes, Jose Alfredo 30 January 2012 (has links)
Previous research offers insights about characteristics of successful superintendents and provides generic lists of attributes (Collins, 2005 and Schleuning, 2003). However, little is known about specific characteristics of Hispanic male superintendents who have been successful in ascending to a superintendent position (Padilla, 2003, Garza, 2003 and Rueda, 2002). Given the current need to select superintendents who reflect the current population changes, further inquiry of the personal and professional attributes from a board presidents’ perspective is needed with a specific focus on male Hispanics who have been selected to serve as superintendent. The purpose of the study is to identify attributes (characteristics) that Texas school board presidents believe are important when having selected a Hispanic male superintendent. The study investigated four research questions: (a) the perceptions of Texas public school board presidents regarding the most important personal attributes when having selected a Hispanic male superintendent; (b) the perceptions of Texas public school board presidents regarding the most important professional attributes when having selected a Hispanic male superintendent; (c) the size (student enrollment) of a school district affect the perception of school board presidents regarding the important attributes; and (d) geographic location affect the perception of school board presidents regarding the important attributes? The study followed a quantitative research paradigm. A descriptive research design approach was used. Thus, a survey was used as instrumentation to collect data (Schleuning, 2003). Texas public school board presidents’ who were serving, and who selected and hired Hispanic male superintendents for 2008-2009 school year were surveyed. Data was analyzed: using descriptive statistics including means and standard deviations, one-way analyses and analyses of variance. Findings revealed that Texas public school board presidents regarding the most important personal attributes when having selected a Hispanic male superintendent are; level of education, previous experience in school administration, and years of experience in education. The most important professional attributes are; honest/fair standards, personal integrity, and visionary leadership. Findings also suggest that enrollment size and geographic location does not affect the perception of school board presidents when selecting a Hispanic male superintendent. / text

Austin chalk fracture mapping using frequency data derived from seismic data

Najmuddin, Ilyas Juzer 30 September 2004 (has links)
Frequency amplitude spectra derived from P-wave seismic data can be used to derive a fracture indicator. This fracture indicator can be used to delineate fracture zones in subsurface layers. Mapping fractures, that have no vertical offset, is difficult on seismic sections. Fracturing changes the rock properties and therefore the attributes of the seismic data reflecting off the fractured interface, and data passing through the fractured layers. Fractures have a scattering effect on seismic energy reflected from the fractured layer. Fractures attenuate amplitudes of higher frequencies in seismic data preferentially than lower frequencies. The amplitude spectrum of the frequencies in the seismic data shifts towards lower frequencies, when a spectrum from a time window above the fractured layer and below the fractured layer is compared with each other. This shift in amplitudes of frequency spectra can be derived from seismic data and used to indicate fracturing. A method is developed to calculate a parameter t* to measure this change in the frequency spectra for small time windows (100ms) above and below the fractured layer. The Austin Chalk in South Central Texas is a fractured layer and produces hydrocarbons from fracture zones with the layer (Sweet Spots). 2D and 3D P-wave seismic data are used from Burleson and Austin Counties in Texas to derive the t* parameter. Case studies are presented for 2D data from Burleson county and 3D data from Austin County. The t* parameter mapped on the 3D data shows a predominant fracture trend parallel to strike. The fracture zones have a good correlation with the faults interpreted on the Top of Austin Chalk reflector. Production data in Burleson County (Giddings Field) is a proxy for fracturing. Values of t* mapped on the 2D data have a good correlation with the cumulative production map presented in this study.

Determining the individual attributes influencing professional male rugby athlete value in South Africa

Thuynsma, Wiehan Francois 11 August 2012 (has links)
South Africans are very much a sporting nation with the ability to host and compete on the world stage in classic fashion. Through sport and inspirational leadership South Africans have united as one nation behind any particular sport discipline.To this end a qualitative research study was conducted with key stake holders within the South African Super Rugby industry. Structured interviews were conducted to highlight or unearth attributes or factors that may or may not influence Super Rugby athlete value when contract discussions took place.The research found that although rugby player contract offering is based on physical performance measures there are other factors which can be attributed to an individual that may impact that player’s perceived value. These attributes can and usually do vary between individuals. The research managed not only to highlight a number of attributes that are relevant to professional rugby player value but created a basis from which more research can be conducted enhancing knowledge around South African Super Rugby players. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

Mea Familia: Ethnic Burial Identifiers In St. Michael's Cemetery, Pensacola, Florida

Giroux, Amy 01 January 2009 (has links)
Grave markers from St. Michael'ss Cemetery in Pensacola, Florida, were studied for evidence of ethnicity and acculturation. The 1,447 grave markers dating from 1870 to 1939 were used to test two hypotheses: 1) the grave markers for ethnic groups represented in the cemetery during the project's time period have identifiable sets of burial attributes; and 2) changes in the visible ethnic attribute sets show evidence of the acculturation of ethnic groups over time. Physical attributes pertaining to grave markers, and personal characteristics (e.g. sex, age) for the individuals inscribed upon the markers were collected for analysis. Historical sources were used to assign ethnicity to each marker by determining the ancestry of the individuals memorialized. Grave marker attributes for ten ethnic groups were examined. The statistical results indicate a correlation of ethnicity with marker attributes. Central Europeans had the most identifiable preferences including large markers, vertical markers, floral design motifs, and headstone molding. Other observable ethnic patterns include the use of family markers, non-marble materials, horizontal markers, relationship wording, and religious symbolism. Spatial analysis illustrates that ethnic markers were dispersed across the cemetery; this lack of segregation in the graveyard may be due to acculturation. However, the diachronic changes in burial identifiers cannot be clearly ascribed to the acculturation of immigrants. Use of marble materials and the height of markers diminished for all ethnic groups. Changes in the memorialization industry were likely contributing factors to differences in attribute selection over time. Therefore, while ethnic burial identifiers are statistically visible in the cemetery landscape, attribute changes are not exclusively caused by acculturation.

Routinization of Sustainable Innovation in Public Sector (A LEED Analysis)

Langar, Sandeep 07 June 2012 (has links)
Innovation can be defined as "The use of non-trivial change and improvement in a process, product or the system that is novel to the institution developing the change" (Slaughter1998). And once an innovation is constantly used by an organization on a regular basis, it leads to routinization. Rogers (2003) defines routinization as "when an innovation has become incorporated into the regular activities of the organization and has lost its separate identity." We also know from the prior research that the innovation could be segregated as per its technical attributes (process or product Innovation), types of innovation (incremental or radical innovation) or economic attributes (direct or indirect economic innovation).Through this study we are trying to observe whether public sector organizations routinize sustainable innovations that are used in the initial projects, and can a relationship be established between the selected attributes of those innovations including process-product, direct-indirect, radical-incremental innovation that may explain their routinization. The LEED Checklist was used as the baseline for studying routinization in public sector organizations. A group of four public sector organizations namely: Arizona State University, University of Florida, City of Austin and City of Seattle were selected on the basis of the constraints that were identified in the early stages of the study. Upon selecting these organizations the LEED Checklists were analyzed and the routinized credits were segregated. The LEED Checklist we segregated on the basis of the attributes of the innovation. To confirm the accuracy of the sorting process an Inter-Rater Reliability was established with the help of an expert panel. The results determined from the segregation process were made to overlap on the routinized credits from the LEED Checklist and the data retrieved was used for the final analysis. During the process of establishing the final results for this research, we segregated the general credits from the prerequisites to avoid any skewing of the results considering that both types of credits were based on different concepts. The results show that public sector organizations do routinize sustainable innovations that were used in the initial projects, and incremental innovation diffuses faster than the radical innovation; product innovation diffuses faster than process innovation; and direct economic innovation diffuses faster than the indirect economic innovation. / Master of Science

Consumer Choice of Hotel Experiences: The Effects of Cognitive, Affective, and Sensory Attributes

Kim, Dohee 02 August 2011 (has links)
Understanding the choice behavior of customers is crucial for effective service management and marketing in the hospitality industry. The first purpose of this dissertation is to examine the differential effects that cognitive, affective, and sensory attributes have on consumer hotel choice. The second purpose is to examine the moderating effects of consumer choice context on the relationship between the cognitive, affective, and sensory attributes and hotel choice. To achieve these two purposes, this dissertation includes the design of a choice experiment to examine how cognitive, affective, and sensory attributes predict consumer hotel choice using multinomial logit (MNL) and random parameter (or mixed) logit (RPL) models. For choice experiments, the main objectives are to determine the choice attributes and attribute levels to be used for the choice modeling and to create an optimal choice design. I used a Bayesian D-optimal design for the choice experiment, which I assess from the DOE (design of experiment) procedure outlined in JMP 8.0. The primary analysis associated with discrete choice analysis is the log-likelihood ratio (LR) test and the estimation of the parameters (known as part-worth utilities), using LIMDEP 9.0. The results showed that the addition of affective and sensory attributes to the choice model better explained hotel choice compared to the model with only cognitive attributes. The second purpose is to examine the moderating effects of choice context on the relationship between cognitive, affective, and sensory attributes and hotel choice. Using a stated choice model, respondents were randomly divided into two different groups and asked to evaluate their preference for two differently manipulated choice sets. For this purpose, it is necessary to include interaction effects in the choice model. This study identified the differences among choice criteria based on two different contexts. Among eight interaction effects, four interaction effects with the contexts -- price, comfortable, room quality, and atmosphere -- were statistically significant on hotel choice. The findings provide hotel managers with important insights and implications in terms of target segmentation, product development, and marketing communication strategy. / Ph. D.

A framework for comparing heterogeneous objects: on the similarity measurements for fuzzy, numerical and categorical attributes

Bashon, Yasmina M., Neagu, Daniel, Ridley, Mick J. 09 1900 (has links)
No / Real-world data collections are often heterogeneous (represented by a set of mixed attributes data types: numerical, categorical and fuzzy); since most available similarity measures can only be applied to one type of data, it becomes essential to construct an appropriate similarity measure for comparing such complex data. In this paper, a framework of new and unified similarity measures is proposed for comparing heterogeneous objects described by numerical, categorical and fuzzy attributes. Examples are used to illustrate, compare and discuss the applications and efficiency of the proposed approach to heterogeneous data comparison and clustering.

AN XML SCHEMA FOR AIRBORNE TELEMETRY BASED ON THE IRIG TMATS STANDARD

Scardello, Mike, Harris, Jim, Downing, Bob 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / XML is a simple and powerful way to handle on data transfers between organizations, applications and/or computer systems. Currently, there is a significant effort within NASA to transition to XML vocabularies as the means of exchanging electronic data. XML can provide a useful way to transfer telemetry attributes data between customers and systems. The current standard for airborne telemetry data description is the Telemetry Attributes Transfer Standard (TMATS). TMATS is a well-defined, structured specification that will map into XML extremely well. This makes XML an excellent choice to supplement TMATS for the interchange of telemetry attribute information. The Western Aeronautical Test Range (WATR) at NASA Dryden Flight Research Center (DFRC) is defining an XML Schema that will be used in support of the WATR Integrated Next Generation System (WINGS). This paper describes this work in progress.
