The recent paper aims at showing the importance of the blended learning to develop skills of Object-oriented programming (OOP) for vocational diploma students of instructional technology at faculty of education. The random study sample was formed of (17) students of the vocational diploma in the year (2018-2019) Two tools were used in the research including an accumulative test to measure the cognitive aspect of Object-oriented programming ( OOP) As for the research findings. The cognitive accumulative test and the note card for the vocational diploma students showed differences with statistical significance at significant level( ≤ 0. 05) between arithmetic means grades in the pre and post applications for the benefit of the post application.

: This thesis extends the Graphical User Interface of a prototype multi-relational database front-end system, called Amadeus. System enhancements are realized through the application of Object-Oriented Programming (OOP) and Human-Computer Interface (HCI) design principles. Knowledge gained from each topic has been incorporated into the design and implementation of a Form-based interface for database data entry and display. The focus of this thesis is divided between two issues: the development of a set of tools for creating and using Form objects; and the design of the Form object itself. Form creation is accomplished using an application program called the Interface Editor module. The Interface Editor is one of six modules which, together, comprise the Amadeus system. Form manipulation occurs in a second application which implements basic program methods for controlling Data entry and display processes. Design and implementation of this thesis was accomplished using the Prograph programming language and development environment, which provided a basic set of system classes essential to the implementation of the Form object and Graphical User Interfaces....

Shopping centres are an integral part and a critical component of urban cities in most economies. Typically, the shorter refurbishment cycle and frequent tenant replacements in shopping centres cause excessive use of building materials over its service life. This drastic use of resources, consequently, increase life cycle embodied energy (LCEE) and life cycle material cost (LCMC) of shopping centres. Therefore, careful selection of materials is vital to reduce the negative environmental impacts and material costs. Current research on the implications of material choices on LCEE and LCMC of shopping centres are insubstantial and decisions makers are left with limited information to make better selections. Therefore, selection of energy efficient, cost-effective and environmentally responsive materials and assemblies has been a critical process for the professionals who are involved in decision-making. This paper proposes the use of object-oriented programming (OOP) to develop a mathematical model to generate combinations of building assemblies with minimum LCEE and LCMC of shopping centres through material selection. The model is based for sub-regional shopping centres in Australia, yet can be applied for any similar property type with modifications to databases and model architecture. However, scope of this paper is limited to the development of model architecture with detailed explanations on databases and computing core development. Even though, the detailed presentation of development of OOP structure provides proper insight to the mathematical core for future application.

A large set of object-oriented programming (OOP) languages exists to realize software for different purposes. Companies often create variants of their existing software by copying and modifying them to changed requirements. While these so-called clone-and-own approaches allow to save money in short-term, they expose the company to severe risks regarding long-term evolution and product quality. The main reason is the high manual maintenance effort which is needed due to the unknown relations between variants. In this paper, we introduce a model-based approach to identify variability information for OOP code, allowing companies to better understand and manage variability between their variants. This information allows to improve maintenance of the variants and to transition from single variant development to more elaborate reuse strategies such as software product lines. We demonstrate the applicability of our approach by means of a case study analyzing variants generated from an existing software product line and comparing our findings to the managed reuse strategy.

As a powerful and object-oriented graphical modeling language, Unified Modeling Language (UML) has been introduced into the design and development of safety-critical computer systems. However, UML model is difficult to reflect the concurrency and consistency of constraint rules between objects and impossible to completely demonstrate the dynamic behavior characteristics of a system. Further, it cannot be directly expressed and analyzed by mathematical tools. Petri net modeling technology uses graphical element place and transition to clearly describe the internal interactions of a system. Meanwhile, Petri net has mature mathematical analysis methods. We have proposed to combine these two tools for designing and analyzing a system with a set of transformation rules from UML statecharts to Petri net. In this paper, an automatic conversion tool is introduced. The tool performs the transformation with three steps as follows: (1) Transforming UML model into XML document, which makes information extraction of the UML model become easier. (2) Analyzing semantics of UML model and Petri net model, then designing data structure for transformation, and completing the transformation based on the transformation rules. (3) Analyzing the transformed Petri net model to verify the characteristics of the UML model. The transformation rules and the tools are developed based on a new railway interlocking system.

Efficient and high-quality design of the substation automation systems has always been a real challenge. The problem of identification and location of information in the system and the description of information processing activities is a significant design problem. Information modeling is aimed at resolving it. An efficient approach to information modeling can significantly improve substation automation system development process. In this paper we propose the usage of the Unified Modeling Language (UML) as a main modeling language for expressing substation information models. UML was specified by Rational Software Corporation in 1997. Today, UML is adopted by the Object Management Group as an object-oriented modeling language with formally defined syntax and semantics. As expected, UML could be widely accepted in various industries (software, telecommunications, medicine, electro-industry, aero-industry etc.). The modeling approach is explained on one typical small-range 35 kV/10 kV distribution substation. Modeling steps: system usage specification, system structure specification, and behavior and constraints specification are described together with explanation of usage of some UML diagrams and modeling concepts.

LabVIEW has become a popular environment to develop data acquisition and control systems in aerospace simulation facilities such as those found at the aerodynamics laboratory of the National Research Council of Canada. These programs are usually developed as structured programs but with time evolve into ad hoc programs. object oriented programming (OOP) is a well established technique that has many advantages over these traditional approaches but applying OOP in LabVIEW-graphical object oriented programming (GOOP) -presents some unique challenges. However, the advantages make the effort worthwhile. The aerodynamics laboratory is undertaking a redesign and rebuild of its data acquisition and control systems in all its facilities. The new systems are required to have greater commonality, portability, flexibility, reliability, expandability and maintainability designed and built in from the start. One key to these improvements is modularity. Another is a common set of standards, policies and approach applied throughout the Laboratory. Envisioned is a system made up of subsystems with common interfaces and running common code where possible. The system should be able to be reconfigured and expanded by rearranging and adding subsystems. To some, all these requirements nicely match the properties of GOOP. A complete design in unified modeling language (UML) was done for such systems and applied to the acquisition and control system for the 0.9 m times 0.9 m pilot wind tunnel, the 5m vertical wind tunnel and to the icing spray system for the 3 m times 6 m open-circuit propulsion and icing wind tunnel to demonstrate the validity of the approach. However, the LabVIEW environment continues to evolve. LabVIEW 8.2 now incorporates GOOP as a native environment. While the new implementation offers many advantages and added functionality such as inheritance and an improved class structure, it breaks continuity with GOOP of the past thus some rethinking and redesign are required to keep up with the changes.

UML (Unified Modeling Language) is a kind of object-oriented modeling language. The conception of UML and its main content is briefly introduced. The modeling application of UML in cement MES equipment management system is studied. Based on the system demand analysis, combining modeling tool Visio, the demand model, static model and dynamic model are established.

Regardless of the large number of Object-Oriented (OO) modeling languages currently being used in the Information Systems (IS) modeling process, unavailability of an OO modeling language that can be used in both the analysis and design phases disintegrates the two phases. The problem is, such disintegration can lead to a high level of missing information in the real world system from the analysis phase to the design phase. The approach of this study is to propose a framework to produce design phase models from analysis phase models using ontology based Unified Modeling Language (UML), thereby integrating the two phases. The results obtained from the porposed framework involve: a consructed language which can be used in generating the analysis phase scripts; and the development of script files based on the UML constructs at the analysis and design phases to automatically generate the UML scripts for those two phases. Since this study is a part of an ongoing research study, it can be concluded that, at the end of this study (1) both analysis and design phases would be able to integrate using a common OO modeling language (2) the manual work involved in the current analysis and design modeling would be reduced (3) the complexities and difficulties faced by the modelers (By modelers we mean the analysts and designers who are doing the analysis and design phase modeling) in using UML modeling tools would be reduced.

El presente artículo surgió como una iniciativa académica en la cual se observa que las áreas de conocimiento en el desarrollo de software bajo el paradigma de Programación Orientada a Objetos - POO está confrontado por un modelo de almacenamiento de datos de tipo relacional lo que plantea dos escenarios diferentes que los desarrolladores tratan de mitigar a través de conversiones entre tipos o utilizando herramientas intermedias como el mapeo de objetos relacional que traen ciertas ventajas y desventajas, y por lo cual, se planteo dentro del proyecto la posibilidad de utilizar un motorde almacenamiento de tipo no relacional o NoSQL. Con el diseño y desarrollo del framework para generar aplicaciones web, el usuario podrá definir los objetos que considere incluir en la aplicación, los cuales se almacenarán en el motor MongoDB, el cual, organiza los datos en forma de documentos. La estructura dinámica de estos documentos se puede utilizar en gran cantidad de proyectos, incluyendo muchos que tradicionalmente funcionarían sobre bases de datos relacionales. Con el objetivo de socializar y evaluar el trabajo realizado, se diseñaron algunos instrumentos para recopilar información de usuarios con experiencia en el sector de las bases de datos y el desarrollo de software. Como resultado se resalta que los desarrolladores de software tienen claro los conceptos de persistencia de objetos a través del mapeo objeto relacional (ORM), que el aprendizaje de estas técnicas de desarrollo de software a través de la implementación de código propio o de la utilización de API´s tiene un grado alto de complejidad y en su mayoría (un 60%) son conscientes que estas implementaciones generan un bajo rendimiento en las aplicaciones. Además, se resalta la apertura de estos a optar por otras alternativas para organizar y almacenar la información, diferentes al enfoque relacional utilizado desde hace varios años.

LibHalfSpace: A C++ object-oriented library to study deformation and stress in elastic half-spaces

Moving from C to C++

This study empirically evaluates how various practices and principles of object-oriented programming (OOP) impact the sustainability and scalability of software projects. A detailed analysis of real-world projects is carried out, considering aspects such as encapsulation, code reuse, modularity, and the application of inheritance and polymorphism. The goal was to identify patterns and best practices contributing to efficient and adaptable software development. The main results highlight that the adoption of OOP practices, such as encapsulation, code reuse, modularity, inheritance, and polymorphism, can be essential for efficient and adaptable software development over time, effectively addressing scalability and sustainability challenges in real-world projects.

At least since the first PISA surveys, the intentions of education are increasingly expressed in terms of competencies instead of learning goals. In consequence, learning outcomes should be measured in terms of these intended competencies as well. This holds for large-scale investigations like PISA as well as for the very small scale that is represented by the examinations that a single teaching person performs with his/her students. Yet, to assure validity, competency measurement requires proper models for competency structure and levels, which are based on empirical research. The goal of this project is to identify a set of relevant competencies in the domain of object-oriented programming (OOP), to develop a suitable competency model to represent their structure and to construct proper corresponding test instruments. This paper describes a study on the outcomes of several assignments that represents one step of this process with focus on the subdomain of data structures. The data were collected during an introductory lecture on programming in the winter term 2015/16. We analyzed the student solutions of three mini-projects that deal with the implementation of abstract data, applying a specific e-assessment system to score the students' solutions. To find suitable item sets that could be used for the definition and measurement of certain competencies, different methodologies were applied that are based on classical test theory as well as on contemporary Item Response Analysis. Up to now, several suitable item sets for the competencies were identified, which are required to implement and operate 1- and 2-dim arrays, linked lists, and binary trees.
