Security Checkpoints

Digital vision technologies emerged exponentially in all living areas to watch, play, control, or track events. Security checkpoints have benefited also from those technologies by integrating dedicated cameras in studied locations. The aim is to manage the vehicles accessing the inspection security point and fetching for any suspected ones. However, the gathered data volume continuously increases each day, making their analysis very hard and time-consuming. This paper uses semantic-based techniques to model the data flow between the cameras, checkpoints, and administrators. It uses ontologies to deal with the increased data size and its automatic analysis. It considers forensics requirements throughout the creation of the ontology modules to ensure the records’ admissibility for any possible investigation purposes. Ontology-based data modeling will help in the automatic events search and correlation to track suspicious vehicles efficiently.

By analyzing the attributes of three-dimensional space data model, the integrated 3D spatial data adopts object-oriented method for digital landslide modeling. It achieves spatial data modeling for landslide geological entity. An experimental case is given to indicate the feasibility of this approach for spatial data modeling.

Query Model

The application requirement of Geospatial data is increasing and complex as it is getting numerous as a result of furthering study on geosciences. Based on a deeply research on Oracle Spatial storage management mechanism, this paper proposed a method that applies the graph theory to domain of optimizing spatial query of massive geographical data, and established a geospatial data query model in order to settle a problem of lower spatial query efficiency in geospatial database. Combining with the practical applications, this paper did a conventional spatial query test and a spatial query based on geospatial data model respectively. The result is that the spatial query based on geospatial data query model has a better efficiency than that on conventional method. Besides, this model can greatly improve the spatial query performance and this improvement will be increasingly apparent as the data volume increases.

The idea to write music for silent films, both in a form of written-down scores and composed live has experienced its renaissance for more than ten years. Thanks to a quite decent number of preserved theatre instruments and also due to the globalisation and wide data flow options connected with it, the knowledge and interest in Anglo-Saxon tradition of organ accompaniment in cinema were able to spread away from its place of origin. The article is the first part of four attempts to present the phenomenon of combination of the art of organ improvisation with cinematography and it was based on the fragments of the doctoral thesis entitled “Current methods of organ improvisation as performance means in the accompaniment for silent films based on the selected musical and visual work”. The dissertation was written under the supervision of prof. dr hab. Elżbieta Karolak and was defended at the Ignacy Jan Paderewski Academy of Music in Poznań in 2020. The article touches on the initial phase of the development of silent cinema from 1895 to 1909. Having differentiated the terms of typical organ improvisation and the art of improvisation for silent films, the article describes the development of cinema art. From the praxinoscope invented by Émile Reynaud, through the cinematograph and the Kinetoscope (Dickson), Vitascope (Jenkins and Armat) and Bioscop (Skladanowsky brothers), it finally discusses the process how the Lumière brothers invented the cinematograph. It its further part, it presents the development of cinematography based on the improvements in theatre introduced by Méliès. The whole text serves as a basis for more parts of the article touching on the issues of the sound added to silent films and the creation of the theatre type of the pipe organ.

Introductory Course

The present study examines the difficulties novice data modelers face when asked to provide a data model addressing a given problem. In order to map these difficulties and their causes, two short data modeling problems were given to 82 students who had completed an introductory course in database modeling. Both problems involve three entity sets with relationships between them, either ternary or binary. The students' solutions were classified according to the types of errors they committed. More than half of the students provided faulty solutions. After an analysis of these results, open interviews were conducted with a selected group of students in order to figure out the reasons underlying the students' erroneous decisions regarding the data model. Among the reasons for their erroneous solutions were insufficient experience, lack of reflection on their solution, and lack of immediate feedback. In addition, the authors suggest instructional modifications derived from the research results.

Universal Standard

The goal of the article is to develop a universal (standard) data model that allows you to get rid of the need for a costly policy of doing extra work when developing new ones or transforming existing relational databases (RDBs) caused by dynamic changes in the subject domain (SD). The requirements for the developed data model were formulated. In accordance with the formulated requirements, the data model was synthesized. To simplify the process of creating relational database schemas an algorithm for transforming the description of the subject domain into the relations of the universal basis of the developed model was proposed. The scientific novelty of the obtained results is: a data model that, unlike known ones, allows us to simplify the creation of RDB schemas at the stage of logical design of relational databases, under the conditions of dynamic changes in subject domains, due to the introduced universal basis of relations, as a means of describing structures and the presentation of data for various SDs has been developed.

The Creation

LMNL provides a markup syntax for annotating arbitrary ranges, irrespective of hierarchical relations, in text. A LMNL processor can parse this syntax (or any other syntax, if mapped) into a generalized data model, which can be queried and processed. Among the applications that LMNL supports readily is the creation of visual "sketches" of the markup on a document, e.g. using SVG. Such sketches can discover and depict any range relations of interest. It turns out the overlap is often less interesting than the hierarchies. Examining texts showing overlapping hierarchies (MCH or multiple concurrent hierarchies) suggests some interesting things about the evolution, purposes and uses of the OHCO (ordered hierarchy of content objects) as a concept applied to "documents" or literary artifacts in general— and by implication of any hierarchical data model such as XML.

The paper is a logical continuation of the previously published work, which was dedicated to the creation of the data manipulation methods. Based on the previously created binary relational data structure we perform mappings of the ALC extension into relational data model (RDM). The results of previous research namely data structure RM2 and mappings of the basic ALC concepts into RDM was used in this paper.

As to the complexity data transmission and processing of web to print（W2P） system, The input and output of these data are analyzed and classified in this paper, based on the actual demand of ShangHai TongKun Digital Printing Enterprise, structure analysis method are used to construct the data model of W2P as a form of Data Flow Diagram(DFD), and then the single order’s business flow model are built with Uniform Model Language(UML). At last, both the two models are combined to illustrate the corresponding relationship in the data exchanges. This study is helpful to analyze data of W2P system and can decrease risk during software’s development.
