Heterogeneous Database Browsing in WWW Based on Meta Model of Data Sources
2001
This paper describes a development principle and technique for a simple universal multiple database browser. The browser operates by getting information from metamodel of data sources and actual data from legacy data sources. Every element such as entity, field, and relation is mapped to some component of HTML page with appropriate structure and layout. Many templates of information layouts can be created allowing to dynamical changing of HTML page to acceptable user interface. The wrappers are used to provide browser with actual data and to act as mediators between data sources and browser. This approach allows to quickly describing new data sources, creating wrappers, making modifications…
On the definition of generic multi-layered ontologies for urban applications
2000
Cooperation of information systems is essential for providing decision support for urban management applications. This involves sharing data across collections of the heterogeneous information systems that are used to manage large urban infrastructures. The objective of this work is to define a spatial ontology to describe key features of urban applications, providing a foundation for semantic reconciliation among heterogeneous spatial information sources. We propose a multi-layered ontologies definition framework consisting of ontology layers which are composed of a generic functional structure and one or more domain ontologies. The functional structure embodies general ontological concept…
Interactions between contingency, organizational IT factors, and ERP success
2009
PurposeThe purpose of this paper is to examine the impact of some organizational information technology (IT) factors (i.e. IT assets, employees' IT skills, IT resources, and satisfaction with legacy IT systems) and their interacting effects with two contingency factors (i.e. organization's size and structure) on enterprise resource planning (ERP) system success.Design/methodology/approachSurveys were conducted in two European countries. Respondents came from diverse, private, and industrial organizations. Relevant hypotheses were developed and tested using a structural equation modeling technique.FindingsThe analysis supported – partially or fully – six of the eight hypotheses formulated. F…
Process Drama Based Information Management for Assessment and Classification in Learning
2013
In this chapter we present a formal description of information management for assessment and classification in learning. The description is supported by a structure related to drama process for learning. Our logic follows the idea of invoking uncertainties using underlying categories, and the language of processes in ‘drama process’ is taken to be BPMN (Business Process Modelling Notation).
Biproportional Method for Analysing Interindustry Dynamics: the case of France
1990
Two elements are being presented in this paper: (1) A new and original method for analysing matrix dynamics, called the synthetical biproportional projector method (SBP), which can be used to project input–output tables and compare one with another. (2) Some results for France for the important period 1970–85. The paper starts with the observation that no systematic study of the change in the French productive structure as displayed In the input–output tables (tableaux entries-sorties in France) has ever been made. This is unfortunate, since a complete series of data is now available concerning a key period of the French economic evolution including the petroleum crisis, European integratio…
The integration of information technologies in the knowledge based organizations
2016
Relations between the users' expertise, complexity of tasks to be solved by knowledge-based organizations and mission of smart information systems, is a multi-dimensional structure that should provide the necessary conceptual framework of sustainable integrated smart development. The users of smart information systems face a variety of problems, such as: system access, data recovery, identifying and retrieving a specific document and its contents, and difficulties associated with understanding and interpreting of the used system on stages and methods following to be used, respectively problems on understanding the meaning of information provided. Using smart information systems and smart da…
Machine Learning: An Overview and Applications in Pharmacogenetics.
2021
This narrative review aims to provide an overview of the main Machine Learning (ML) techniques and their applications in pharmacogenetics (such as antidepressant, anti-cancer and warfarin drugs) over the past 10 years. ML deals with the study, the design and the development of algorithms that give computers capability to learn without being explicitly programmed. ML is a sub-field of artificial intelligence, and to date, it has demonstrated satisfactory performance on a wide range of tasks in biomedicine. According to the final goal, ML can be defined as Supervised (SML) or as Unsupervised (UML). SML techniques are applied when prediction is the focus of the research. On the other hand, UML…
Elaboration of a Critical Paradigm for Interpreting Modern Architecture: The Almost Intangible Essence of Luigi Moretti's Casa del Balilla at Trecate
2021
Modern architecture is not, from a lexical point of view, uniquely definable. The heterogeneity of the twentieth century heritage is therefore a collective wealth that should be protected from the risk of falling into oblivion. In order to avoid this, it could prove fundamental to establish a process of the knowledge of these assets. This should not, however, result in a simple and passive recording of architectural facts: a deep understanding of the complexity of modern architecture, which has as its objective the protection of buildings, could be obtained, for example, through a real and proper decoding of signs, conducted by a critical use of the metalanguage most congenial to the archit…
Computer Simulation Paradigm Regarding the Structure and Mechanical Characteristics of Human Long Bones
2013
Given the complex form of the long bones, a quality method of geometrical modeling which provides a good result is that of the 3D modeling by reconstruction, using the principles of reverse engineering. One of the important problems that shall be taken into consideration while modeling is the one concerning the real structure of the bones. This aspect presents a lot of importance because from the point of view of the mechanical behavior, the bones are neither homogenate structures. In this paper a study of the long bones structures is undergone, and in relation to the modelated element (the human tibia) it is divided in areas (called constructive-anatomical entities) of different mechanical…
Mental Account Barriers and Transaction Purpose: A Romanian Point of View
2013
Abstract The present study encompasses the behavioral model of decision making. Using the models provided by scientific literature, the relationship between the basic structure of mental accounts, transaction utility and consumer decision, together with perceived comfortability. The procedure was carried out using undergraduate students of Lucian Blaga University of Sibiu, with similar proportions of sexes and with resembling ages. Results have shown that influence of mental accounting structuring and transaction utility on decision and perceived comfortability is insignificant, taken into account the differences between sexes. The presented results bring knowledge into the economic behavio…
