The aging of the world population and its serious consequences have made the development of systems adapted to the needs of seniors an absolute necessity. In recent years, technological improvements have favored the development of efficient ...

One of Industry 4.0’s greatest challenges for companies is the digitization of their processes and the integration of new related technologies such as virtual reality (VR) and augmented reality (AR), which can be used for training purposes, ...

Virtual reality (VR) and augmented reality (AR) have already shown their advantages in industrial use during these last years. Nevertheless, the authoring and editing process of virtual and augmented contents are still time-consuming and even more ...

Software development life cycle (SDLC) depicts the necessary software development activities while applying methods in different software types. Previous works documented the software activities either by taking into account the development method or ...

After 25 years, university courses still teach UML modeling to some extent. Also, UML is still the go-to language when practitioners need to model software systems. Evaluating UML models created by students remains a challenge faced by instructors. Some ...

Unified Modeling Language (UML) is the de facto standard for the development of software models, and Object Constraint Language (OCL) is used within UML models to specify model constraints. Several UML/OCL tools provide Model-Driven Engineering ...

Traceability between system requirements and the artifacts produced by the software development process contributes to the development of reliable software. This paper proposes a method of ensuring traceability by automatically generating an initial ...

The modern era of digital world has increased the multitude of defining various domain knowledge. Domain-specific-modeling-languages (DSMLs) propose an efficient manner to incorporate the knowledge of domain expert in software system development. The ...

The increasing pace of change in competition, technology, and complexity of software-intensive systems has increased the demand for rapid, reliable, scalable, and evolvable processes. Agile methods have made significant contributions to speeding up ...

CONTEXT: Resource and time estimation is a critical activity in software projects. In literature, various techniques have been proposed, but it's often difficult to perform them, because of data scarcity in the early stages of a project. We studied this ...

Scrum has become the most popular agile methodology in recent years. It focuses on management and organization of software project, and doesn't provide descriptions about how everything is to be done on a project. This paper presents an approach of ...

Model-driven design is very common nowadays. In this context, the UML/MARTE profile is a well-known solution for real-time, embedded system modeling. This profile enables the functional and non-functional details of the system to be modeled together. ...

Formal description techniques, such as Lotos and Sdl, have been proven as a successful means for developing communication protocols and distributed systems. Meanwhile the Unified Modeling Language (UML) has achieved wide acceptance. It is, however, less ...

This paper proposes a service which searches goods by images and finds a shopping mall site that offers referral services. In the service, images are obtained in various types. For image management, it will be modeled using UML Diagram. Unlike other ...

With the new trend of shifting from traditional architectures towards Service-Oriented Architectures (SOAs) today, the need to model integration becomes increasingly apparent. This study analyzes two main approaches for SOA integration modeling: using ...

Addressing non-functional requirements in Real-Time Embedded Systems (RTES) is of critical importance. Proper functionality of the whole system is heavily dependent on satisfying these requirements. In model-based approaches for development of the ...

This article presents practical experiences and lessons learned in defining and implementing an agile model-driven development process using the MDD tools chain. This process and its implementation inherit the merits of scrum, extreme programming, and ...

This paper analyzes the educational properties of elements in Edu-game from three point including knowledge, intelligence and affection. On this basis, construct model of Edu-game's software system with the application of the Unified Modeling Language (...

UML-based modeling is becoming increasingly popular in many software development projects. One of the key aspects is the possibility to support automatic code generation from UML models while keeping the easy to use modeling abstraction for the software ...

Currently available application frameworks that target at the automatic design of real-time embedded software are poor in integrating functional and non-functional requirements for mobile and ubiquitous systems. In this work, we present the ...
