Research Ontology Data Models for Data and Metadata Exchange Repository

Kamenieva, Iryna January 2009 (has links)
For researches in the field of the data mining and machine learning the necessary condition is an availability of various input data set. Now researchers create the databases of such sets. Examples of the following systems are: The UCI Machine Learning Repository, Data Envelopment Analysis Dataset Repository, XMLData Repository, Frequent Itemset Mining Dataset Repository. Along with above specified statistical repositories, the whole pleiad from simple filestores to specialized repositories can be used by researchers during solution of applied tasks, researches of own algorithms and scientific problems. It would seem, a single complexity for the user will be search and direct understanding of structure of so separated storages of the information. However detailed research of such repositories leads us to comprehension of deeper problems existing in usage of data. In particular a complete mismatch and rigidity of data files structure with SDMX - Statistical Data and Metadata Exchange - standard and structure used by many European organizations, impossibility of preliminary data origination to the concrete applied task, lack of data usage history for those or other scientific and applied tasks. Now there are lots of methods of data miming, as well as quantities of data stored in various repositories. In repositories there are no methods of DM (data miming) and moreover, methods are not linked to application areas. An essential problem is subject domain link (problem domain), methods of DM and datasets for an appropriate method. Therefore in this work we consider the building problem of ontological models of DM methods, interaction description of methods of data corresponding to them from repositories and intelligent agents allowing the statistical repository user to choose the appropriate method and data corresponding to the solved task. In this work the system structure is offered, the intelligent search agent on ontological model of DM methods considering the personal inquiries of the user is realized. For implementation of an intelligent data and metadata exchange repository the agent oriented approach has been selected. The model uses the service oriented architecture. Here is used the cross platform programming language Java, multi-agent platform Jadex, database server Oracle Spatial 10g, and also the development environment for ontological models - Protégé Version 3.4.

Srovnání vybraných způsobů ocenění pro nemovitost typu rodinný dům v Litomyšli a okolí / Comparison of Seleted Methods of Valuation of Family House-type Real Estate in Litomyšl and its Surroundings

Plchová, Monika January 2011 (has links)
Diploma Thesis "Comparison of selected methods of valutation of a family house - type estates in Litomyšl and it's surroundings" describes the way of assesing, compares these methods and recognises the difference between them. The practical part is especially focused on assesing of choosen family houses by the cost approach, comparative public notice, comparative non-promulgation, standard price and price at present time. At the end of diploma thesis there is provided how much the aspect of job opportunities influences the price of family houses, which was counted by the comparison method.

Řízení kvality - audit produktu z pohledu zákazníka / Management quality - The customer view of a product audit

BUCHLOVIČOVÁ, Kateřina January 2008 (has links)
This graduation theses deals with quality, quality control system, ISO rules and audit of product. Chosen firm is characterized in the practical part of the document, there is explanation of the implementation ISO rules in company. Then I occupy by creation of instruction: quality monitoring in the workroom. Other part of document deals with characteristic of monitored product parameters and using FMEA method. I get at product values of customer and I design methodics for finding customers satisfaction in the ending of document.

Correlación de los valores Nspt con Ndpl en los suelos arenosos de la Asociación Agropecuaria Sumac Pacha - Lurin

Rojas Parco, Frank Gabriel, Zamora Ortiz, Jhow Mckevin January 2015 (has links)
El presente trabajo de tesis, trata sobre las correlaciones de 2 diferentes equipos de penetración, en los suelos arenosos de la Asociación Agropecuaria Sumac Pacha ubicado en el distrito de Lurín, a fin de establecer ecuaciones de correlación entre ellas. Para el desarrollo de la presente investigación, cuyo objeto es correlacionar el número de golpes del ensayo SPT con el número de golpes DPL. Para ello se realizaron los ensayos de campo en un terreno Arenoso de 25x40m (1000 m2) de la Asociación Agropecuaria Sumac Pacha, ubicado en el distrito de Lurín. El ensayo SPT, es un ensayo de campo estandarizado que sirve para la determinación de la resistencia a la penetración del suelo y que se realiza dentro de una perforación, desde la superficie del terreno y con una profundidad y penetración definida. El ensayo DPL es un ensayo de campo para la determinación de la resistencia a la penetración del suelo. Se realiza el ensayo en terrenos arenosos con profundidades de hasta 8m. Se realizó un estudio tipo no experimental transversal, que se llevaron a cabo en un depósito arenoso con poca presencia de finos. Se realizaron las caracterizaciones correspondientes por medio de ensayos de granulometría, Límites de Attemberg, Corte Directo, Humedad natural, Densidad natural. Los Ensayos de Penetración se hicieron en suelos con características SP y SM en su mayoría, y de alto estado de densidad que varía de 1.483gr/cm3 hasta 2.182gr/cm3. Los resultados obtenidos sobre la correlación entre los valores NSPT y NDPLfueron 2 ecuaciones que fueron hallados por diferentes métodos estadísticos. Concluye que las correlaciones obtenidas serán válidas hasta los 1.80 m de profundidad; siendo las ecuaciones de correlación únicas y exclusivas para la zona de estudio (Terreno de 1000m2 dentro de la Asociación Agropecuaria Sumac Pacha) de donde se puede deducir que el número de golpes NSPT y NDPL son directamente proporcionales. This thesis, deals with two different tools correlations penetration in the sandy soils of the Agricultural Association Sumac Pacha located in the district of LurÍn, in order to establish correlation equations between them. For the development of this research, which principal trial is to correlate the number of strokes of the SPT with the number of strokes DPL. To do field trials were conducted on sandy ground of 25x40m (1000 m2) of the Agricultural Association Sumac Pacha, located in the district of LurÍn. The SPT is a standardized test field serving for the determination of resistance to soil penetration and is performed within a borehole from the earth surface and a defined penetration depth. The DPL assay is a field for determining the resistance to penetration of the soil. The trial in sandy soils with depths of up to 8m is performed. A transverse non-experimental study, which was conducted in a sandy deposit with little presence of fines was performed. The corresponding characterizations by tests of grain, Attemberg limits, Straight Cut, natural humidity, natural density were performed. Penetration tests were done in soil characteristics SP and SM mostly state and high density ranging from 1.483gr / cm3 to 2.182gr / cm3. The results on the correlation between NSPT and NDPL values were two equations were found by various statistical methods. It concludes that the correlations obtained are valid until 1.80 m depth; equations being unique and exclusive correlation for the study area (1000m2 land within the Agricultural Association Sumac Pacha) where it can be deduced that the number of strokes and NDPL NSPT are directly proportional.
