Using the Telemetry Attributes Transfer Standard

Takacs, Theodore, Jr. 10 1900 (has links)
International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Telemetry attributes are the detailed items of information needed for a receiving/processing system to acquire and process data from a given test item. There are currently as many different ways to describe telemetry attributes as there are different organizations which provide them (instrumentation groups and aircraft/missile manufacturers) and use them (telemetry processing systems/test ranges). The Telemetry Attributes Transfer Standard (TMATS) has been developed as a method of standardizing the transfer of telemetry attributes information. This paper describes the TMATS standard and discusses its purpose and application.

Personality Traits as Related to Vocational Interest Patterns

Conekin, Albert McKenzie 12 1900 (has links)
The purpose of the study was to analyze the personality traits of an individual as measured by a standardized personality test instrument and the vocational interest patterns as measured by a standardized vocational interest test. An attempt was made to determine if these identifiable personality traits were related to the ten reordered vocational clusters by means of a simple analysis of variance technique. In order to achieve this purpose, the following hypothesis was developed for investigation: There would be significant differences among the ten vocational clusters identified by the SVIB (Technical Cluster, Intellectual Cluster, Scientific Cluster, Business Cluster, Social Service Cluster, Creative Cluster, Office-Clerical Cluster, Sales Cluster, Concrete Transactions Cluster, and Physical Cluster) on the personality traits as measured by the 16 PF Questionnaire (Sizothymia- Affectothymia, Intelligence, Emotionality-Ego Strength, Submissiveness-Dominance, Desurgency-Surgency, Superego Strength, Threctia-Parmia, Alaxia-Protension, Praxernia-Autia, Artlessness-Shrewdness, Adequacy-Apprehension, Conservatism- Radicalism, Adherence-Self Sufficiency, Integration of Self Concept, and Ergic Tension).

Inference of XML Integrity Constraints / Inference of XML Integrity Constraints

Vitásek, Matej January 2012 (has links)
In this work we expand upon the previous efforts to infer schema information from existing XML documents. We find the inference of structure to be sufficiently researched and focus further on integrity constraints. After briefly introducing some of them we turn our attention to ID/IDREF/IDREFS attributes in DTD. Building on the research by Barbosa and Menelzon (2003) we introduce a heuristic approach to the problem of finding an optimal ID set. The approach is evaluated and tuned in a wide range of experiments.

Attributes and motivation in game-based learning : a review of the literature

Kang, Jina 26 November 2012 (has links)
Since the mid-1980s, various educational games have been developed, and their popularity has implications for the use of games in the classroom. Although research over many years has shown games to be effective in enhancing motivation and improving learner performance, studies that connect specific elements of games and learner motivation are lacking. This report is a literature review of relevant articles on motivation and attributes in game-based learning, including empirical studies and theoretical articles from 2009 to present. Based on the attributes presented by Wilson et al. (2009), the game environments in these studies are reviewed, with a focus on recent studies and trends related to game-based learning. This review also presents an examination of how the recent studies conducted their experiments in order to investigate game attributes and motivation. The relationship between the attributes and learner motivation is discussed. Because of the current lack of research on the relationship between attributes and learner motivation in game-based learning, the results of this literature review can provide insight into the potential use of game attributes. / text

Characterization of VTI media with PS[subscript v] AVO attributes

Gustie, Patrick John 02 February 2015 (has links)
Amplitude variation with offset (AVO) signatures in vertically transverse isotropic (VTI) media vary as the degree of the anisotropy contrast between layers varies. When the contrasts in two parameters (δ and ε) that quantify the VTI elastic anisotropy are varied, the fraction of energy that reflects from a given layer interface as a mode converted shear wave (R[subscript PS]) also varies for specified angles of incidence. Mode-converted (PS[subscript V]) AVO crossplots may potentially be used to map stratigraphic layers exhibiting intrinsic VTI anisotropy with the moderate to high degrees of weak elastic anisotropy that are often attributed to shale formations. Calculated values of reflected, mode-converted energy as a function of angle of incidence (R[subscript PS](i)) are plotted to determine what mode-converted seismic data indicate about the degree of VTI weak elastic anisotropy present in a given layer. These computations involve varying the degree of weak elastic anisotropy, in this case contrasts in Thomsen’s δ and ε parameters, so that the relationship between these parameters and the amplitude variation with offset (AVO) signature can be quantified. Once this relationship is understood, it may be possible to delineate sweet spot areas of shale formations in seismic data according to how the representative points plot on an AVO crossplot. For such crossplots, the y-intercepts of the reflectivity curves in a particular parameterized space are plotted on the x-axis while the slopes of the parameterized reflectivity curves in this parameterized space are plotted on the y-axis. The grouping of points on the mode-converted AVO crossplots according to the contrast in Thomsen’s δ and ε parameters for weak elastic anisotropy is encouraging. This grouping implies that it may indeed be possible to use an AVO attribute map to characterize a given organic shale formation according to its degree of intrinsic VTI anisotropy. This attribute map would be calibrated to known production data in the locality in order to locate which areas of the mode-converted AVO crossplot predict a likely production sweet spot. / text

Contemporary Wahhabism rebranded as Salafism : the issue of interpreting the Qur'anic verses and hadith on the Attributes of God and its significance

Nahouza, Namira January 2009 (has links)
This research studies the theology of those Wahhabis who have now named themselves Salafis. For the purpose of the study, they are referred to as the ‘Wahhabis-self-named-Salafis’ (WSNS). The thesis starts with the observation that the WSNS are usually studied from a political perspective, much less frequently a theological one. Recent research has identified that the theological background of all the different factions of the WSNS is one and the same. This is true for the WSNS who advocate a peaceful way to achieve their goals, as well as those who do not. This thesis aims to explore some of the theological issues that unify these factions. This research demonstrates that, because the WSNS are opposed to the very concept of interpretation of the Qur’an and the hadith, especially when these texts deal with important theological issues such as the Attributes of God, they have developed a vision of Islamic history which is entirely different from the one which had traditionally been accepted by most Muslim scholars and Western academics. They have redefined the notion of Sunnism as it has been known, mostly basing themselves on this single issue. This thesis shows that the WSNS deny the existence of any interpretation ever made by a recognised member of the Salaf (i.e. the Muslims of the first three generations). In contrast, the Sunnis who do not claim to be Salafis, but who nonetheless consider themselves as treading the path of the Salaf (called in the thesis: ‘Sunnis-not-claiming-to-be-Salafis’) are of the view that they did allow interpretation. The WSNS therefore consider that the Ash‘ari scholars (from the main Sunni theological school) had a corrupted creed concerning God. This leads the followers of the WSNS, from across the spectrum of the different factions, to consider that most of the Islamic scholars from the past had actually failed to understand the proper Tawhid, or Oneness of God, which is tantamount to considering them all as misguided, with the notable exception of Ibn Taymiyya and his students, and Muhammad ibn ‘Abd al-Wahhab and his students. The research argues that, by favouring the non-violent factions of the WSNS simply because they are officially opposed to terrorism and suicide bombings, current counter-terrorism strategies are allowing the gradual replacement of the core of the notion of Sunnism to go ahead, thereby fuelling future chaos and confusion in the Muslim community. This thesis highlights the longer term implications of these strategies for the Muslim community and the world at large.

After the goldrush : willingness to pay for concert service and product attributes in South Africa

Larsen, Donovan Jake 16 March 2013 (has links)
After the gold rush that was the recorded music business in the twentieth century, the industry finds itself in a difficult time of severely reduced revenues from recorded works distributed on physical media. As the industry searches for a solution to its problems, this research investigates the potential additional revenues from live music events as an element of the revenue replacement engine. The core objective governing this research was to gain a clearer understanding of concert service and product attributes that are valued by customers and to gauge their willingness to pay for these attributes. Also key to the brief was the goal of understanding the consumer decision-making and buying process with reference to the rules applied in the buying process. The questionnaire used in this research was structured by design and sought to gauge from concert audiences what they were willing to pay for preferred product or service attributes.The findings show that there is a willingness to pay for some concert related product and service attributes and that there are distinct clusters within the respondent population that are distinctly different from each other across a variety of demographic and other metrics. Other than on a single sub-attribute, premium bar facilities, there was no evidence found for using ticket class as an indicator for willingness to pay for service or product attributes or subattributes. There was evidence found, however, that demographic and other metrics could be indicators for willingness to spend on each attribute and subattribute. / Dissertation (MBA)--University of Pretoria, 2012. / Gordon Institute of Business Science (GIBS) / unrestricted

Effect of Branding Gulf Oysters on Consumer’s Willingness to Pay

Acquah, Sarah 15 August 2014 (has links)
Within the East coast and West Coast oyster market, oysters are generally marketed using product attributes and brand name. However the Gulf oyster market does not involve branding. Using choice experiment method and online survey data, the study estimated the effect of branding Gulf oysters on Gulf and Non-Gulf consumers’ willingness to pay. Alternative-specific conditional logit, Nested logit and Alternative-specific multinomial probit methods of analysis were used to investigate the Independence of Irrelevant Alternative assumption made about consumers. Pooled and scaled models were used to analyze the identified data categories from which consumers were found to share the same oyster preferences. The results found that consumers on the average were willing to pay more for the oysters harvested from their own region relative to those harvested from outside their region. They were willing to pay a less for oysters harvested outside their region.

Attribution Standardization for Integrated Concurrent Engineering

Baker, Tyson J. 30 June 2005 (has links) (PDF)
Product design is a creative process, often subject to rapid and numerous design change requirements. To facilitate geometric redesign iterations, Parametric Computer-Aided Design CAD) systems were introduced. To manage the numerous product design iterations produced by parametric CAD systems, Product Data Management (PDM) systems were developed to capture, document, and manage each product revision. PDM has proved effective thus far at managing design history. However, PDM is built upon database management systems (DBMS), which have the capability of doing far more than simply managing product revision history. Product data consists not only of the physical geometry used to describe it, but also of a host of non-geometric data. This non-geometric data is referred to as attributes. Examples of attributes include material properties, boundary conditions, finite element mesh information, manufacturing operations, assembly operations, cost, etc. Downstream Computer-Aided Engineering (CAE) applications apply attributes to (preprocess) the geometry to perform their respective operations. These attributes are not permanently associated with the geometry and may have to be recreated each time the geometry changes. Preprocessing for highly complex CAE analyses can sometimes require weeks of effort. An attribution method is presented which addresses the creation, storage, and management issues facing attributes in the CAD and CAE environments. The research conducted explores the use of database management systems for defining, instantiating, and managing attributes in the CAD environment. Downstream CAE applications may then retrieve the attributes from the DBMS to automate preprocessing. The attribution system results in standardized attribute definitions, which forms the basis for communicating attributes universally among different downstream CAE applications.
