This literature review synthesizes existing research in the field of Service-Oriented Architectures (SOA) from a business perspective and integrates results from 40 works to offer researchers an overview about the existing body of knowledge in this research field as well as a research agenda, which unifies and extends previous efforts. While the literature regarding the technologies and design ...

Software engineering is one of the dominant areas for Computer Science researchers. It is difficult to cover the complete aspects of any domain in a single review paper. Software metric is an important concept that is used to determine the performance, cost and efficiency of different aspects related to software development process. In this paper, I have tried to demonstrate the research relate...

In this paper, we propose a formal model for multilevel databases. This model aims at being a generic model, that is it can be interpreted for any kind of database (relational, object-oriented...). Our model has three layers. The first layer corresponds to a model for a non-protected database. The second layer corresponds to a model for a multilevel database. In this second layer, we propose a ...

Experimenting and building integrated, operational systems in computational vision poses both theoretical and practical challenges, involving methodologies from control theory, statistics, optimization, computer graphics, and interaction. Consequently, a control and communication structure is needed to model typical computer vision applications and a flexible architecture is necessary to combin...

We develop a new framework for analysing finite connected, oriented graphs of valency four, which admit a vertex-transitive and edge-transitive group of automorphisms preserving the edge orientation. We identify a sub-family of ‘basic’ graphs such that each graph of this type is a normal cover of at least one basic graph. The basic graphs either admit an edge-transitive group of automorphisms t...

The contribution gives a short description of the software engineering tool SPaS, particularly considering the graphical flow chart design. SPaS is characterized by its technology-oriented engineering manner and by the in-built verification of its control layout. The graphical flow charts are compiled to a control program written in either of the languages: Instruction List, Structured Text, C ...

Open Aspects are our approach to face unplanned changes in systems that are based on aspect-oriented composition at runtime. They support explicit adaptation models, allowing developers to describe system change events to be observed, and corrective actions to be taken. These events and actions cover both the base system affected by aspects as well as the aspects affecting the base system thems...

ÐHypermedia applications can be defined as collections of interactive and multimedia documents that are organized as a hypertext net. The development of hypermedia applications poses specific problems, such as the need for modeling sophisticated navigational structures, interactive behaviors, and harmonic presentations involving the synchronization of contents. Moreover, the increasing populari...

The objective of this project is to apply some optical data, an object oriented classification approach for monitoring and detecting the changes land cover in north Cote dIvoire where cashew spreading. Two Landsat images TM (1986)/ETM+ (2002) a Sentinel-2 (2022) are used research. method achieved through from object-oriented based on fuzzy logic. For specific methodological approach, we resort ...

Security is a major challenge for all distributed applications; however, it imposes additional concerns and requirements when Service-Oriented Computing (SOC) is used. Therefore, addressing the security issues is critical for the success of any SOC based project. Thus when utilizing service-oriented middleware (SOM), security could be included as part of the SOM architecture. SOM is a concept t...
