A library circulation system for city and special libraries

Purpose – The aim of this research is to model and implement a software system for library circulation, so that all requirements of city and special libraries for electronic business with the library users can be fulfilled.Design/methodology/approach – Object‐oriented methodology is used for modelling of information systems. Modelling is carried out in the CASE tool that supports the Unified Modelling Language (UML 2.0). The software architecture of the system is based on the software components and web services.Findings – The result is a software system for library circulation. The application of the system supports the work with the local database (intranet), as well as with the remote database (internet). Also the application supports the work with different library formats (UNIMARC, MARC21 et al.).Research limitations/implications – The system is integrated into the BISIS system so that communication with the system for cataloguing is carried out via the text server of the BISIS system. For this reaso...

XML editor for search and retrieval of bibliographic records in the Z39.50 standard

Purpose – The purpose of this paper is modelling and implementation of the XML‐based editor for search and retrieval of bibliographic records. Search and retrieval of bibliographic records are enabled by the editor from the remote databases via the Z39.50 protocol. The client application is realized in the Java environment and business logic is based on the XML technologies.Design/methodology/approach – Object‐oriented methodology is used for modelling and implementation of information systems. Modelling is done in the CASE tools that support the Unified Modelling Language (UML 2.0) and implementation is developed in Eclipse environment.Findings – The result is an application for retrieving bibliographic records within the Z39.50 standard. The editor supports the query formulation of the type‐1 that is defined by the Z39.50 standard. The implementation of the editor is based on the XML technologies by which a simple migration to the other query types defined by the standard is enabled. The application is ...

Retrieval of bibliographic records using Apache Lucene

Purpose – The aim of the research is modeling and implementing a software component for the retrieval of bibliographic records using the Apache Lucene retrieval engine.Design/methodology/approach – Object‐oriented methodology is used for modeling and implementation of the bibliographic record retrieval engine. Modeling is carried out in the CASE tool that supports the unified modeling language (UML 2.0), while the implementation is using the Java programming language and open source components.Findings – The result is a software component for the retrieval of bibliographic records that are independent of the bibliographic format used in cataloging. It features great flexibility in terms of configuring search types without the need to change the software implementation.Research limitations/implications – One of the constraints of this system relates to the problem of searching linking entry fields. UNIMARC format defines fields used to link the item being cataloged to another bibliographic item, so those f...

XML editor for UNIMARC and MARC 21 cataloguing

Purpose – The purpose of this paper is to model and implement an extensible markup language (XML)‐based editor for library cataloguing. The editor model should support data input in the form of free text with interactive control of structure and content validity of records specified in the UNIMARC and MARC 21 formats. The editor is implemented in the Java programming language in the form of a software package.Design/methodology/approach – The unified modelling language (UML 2.0) is used for the specification of both the information requirements and the model architecture. The object oriented methodology is used for design and implementation of the software packages, as well as the corresponding CASE tools.Findings – The result is an editor for UNIMARC and MARC 21 cataloguing. The editor is based on the XML technologies by which the two basic characteristics are achieved as follows: a possibility of integrating the editor into different library software systems and, moving to another format requires only t...

XML schema for UNIMARC and MARC 21

Purpose – The purpose of this paper is to create a model for an XML document that will carry information about bibliographic formats. The model will be given in the form of an XML schema describing two bibliographic formats, UNIMARC and MARC 21.Design/methodology/approach – The description of bibliographic formats using the XML schema language may be discussed in two ways. The first one relates to creating an XML schema in a way that all elements of the bibliographic format are described separately. The second way, used in this paper, is creating an XML schema as a set of elements that presents concepts of bibliographic formats. A schema created in the second way is appropriate for use in implementation of cataloguing software.Findings – The result is an XML schema that describes MARC 21 and UNIMARC formats. The instance of that schema is an XML document describing a bibliographic format that will be used in software systems for cataloguing. An XML document that is an instance of the proposed XML schema i...

Modelling and Implementation of Catalogue Cards Using FreeMarker.

Purpose – The purpose of this paper is to report on a study involving the specification (using Unified Modelling Language (UML) 2.0) of information requirements and implementation of the software components for generating catalogue cards. The implementation in a Java environment is developed using the FreeMarker software.Design/methodology/approach – Object‐oriented methodology as well as CASE tools are used to design the software components. The system architecture makes the catalogue cards available from every segment of the library management system, and enables catalogue card updates without recompilation of the source code.Findings – The outcome of the work is a software package, implemented in a Java environment, that generates and displays catalogue cards based on bibliographic records in the UNIMARC format, but it can be easily adapted for the other MARC formats.Research limitations/implications – The package is limited to generating only catalogue cards based on MARC formats. In order to avoid th...

An Approach to Biped Control Synthesis

A novel approach to control synthesis of biped locomotion mechanisms is suggested. The synthesis is carried out in two stages: the stage of nominal regimes (the synthesized control has to ensure the realization of gait in the absence of any disturbance), and the stage of perturbed regimes (the control has to eliminate deviations from the nominals under an additional condition of preserving the stability of the overall System). At the level of perturbed regimes, the proposed control synthesis should ensure the compensating movements such to bring the System ot its nominal during the gait. However, the compensating movements can, as a side–effect, induce the undesirable inertial forces which can influence the mechanism overall stability. To avoid this, it is suggested such a control which ensures that the acceleration of compensating movements does not exceed a value given in advance. In addition, the case is considered when an additional correction of the zero moment point ZMP position is accomplished by different mechanism joints.

Conversion of bibliographic records to MARC 21 format

Purpose – The aim of this research is the conversion of the bibliographic records between the following different formats for bibliographic material processing – the YUMARC (which is a variant of the UNIMARC format in which the Serbian BISIS system operates), UNIMARC and MARC 21 format.Design/methodology/approach – The CASE tools that support the information system developing methodology based on the XML technologies are used.Findings – The result is the specification and implementation of information requirements for the conversion of the bibliographic records created in the BISIS system into the UNIMARC or MARC 21 format.Research limitations/implications – The specification of the rules for bibliographic record conversion is not formalized, so the implementation of these rules cannot be done automatically. If the rules could be formalized, then a generator of the programming code could be developed for the implementation of the rules for the bibliographic record conversion.Practical implications – The r...

Lebesgue measure of a-cuts approach for finding the height of the membership function

Abstract The goal of this paper is to present a procedure for finding the height (the global maximum) of a membership function of a fuzzy set of R n , even for non-continuous membership functions, using the Lebesgue measure of α -cuts. Randomizing the variable and approximating the corresponding function to α -cuts completes the procedure. An algorithm is given for finding the height of the membership function, which is applied to some characteristic examples.
