In the current marketplace, there are maturity models, standards methodologies and guideline that can help an organization improve the way it does business. Software process assessment models, ISO/IEC 15504 and CMMI provide a tool to assess your organization’s software development capability. Experienced assessors make these assessments. However these models don’t supply systematic metrics for software process assessment. Therefore the assessors have used their subjective estimations for quantitative measurement in their software process assessment. This paper defines the basic metrics and presents the standard metrics in categories of process defined by ISO/IEC 15504 to assess software process quantitatively and objectively. In addition, presents an essential guideline to identify your organization’s condition by suggesting a process maturity assessment metrics to apply the standard metrics to your organizations.

Agents are designed to be autonomous problem-solvers, possibly communicating with other agents and users, and are therefore equipped with sufficient cognitive abilities to reason about a domain, make certain types of decisions themselves, and perform the associated actions. In this paper, we propose to integrate agents in a Cooperative Intelligent Decision Support System. The resulting system, called MACIDS is designed to support operators during contingencies. During the contingency, the operators using MACIDS should be able to: gather information about the incident location; access databases related to the incident; activate predictive modeling programs; support analyses of the operator, and monitor the progress of the situation and action execution. In MACIDS the communication support enhances communication and coordination capabilities of participants. A simple scenario is given, to illustrate the feasibility of the proposal.

In recent years, the significance of automated generation of object-oriented code from UML diagrams has increased due to its benefits, such as, cost reduction and accuracy. Consistency Checking between UML diagrams, and ensuring accuracy, maintainability, efficiency, and completeness of the generated code are the main concerns in this area. This paper extends our work on a tool called UJECTOR for automatic generation of executable Java code from UML diagrams. A set of three UML diagrams, i.e., class diagram, sequence diagrams and activity diagrams are input to the tool to generate completely executable Java code automatically. The object-oriented code structure is built from class diagram, methods’ flow of control is created through sequence diagrams, and object manipulations are included by activity diagrams from the implemented approach in UJECTOR. The extension includes a more detailed overview of the code generation tool regarding its architecture and code generation process. Two detailed case studies are presented to validate the generated code from the code generation tool. We also compare UJECTOR with the existing research-based, commercial and open-source tools. The evaluation results show that the generated code from UJECTOR is fully functional and understandable.

Component-based software engineering is an emerging paradigm for software development. Benefits of component-based development include significant reduction in the development cost, time and improvement in the dependability requirements. Commercial off-the-shelf (COTS) components are used without any code modification and inspection. When such components are integrated to build safety-critical systems, faults within individual COTS components or faults due to their collaboration may cause catastrophic failures. Therefore, for systems with high dependability requirements, it is essential to incorporate ways for tolerating the software faults at architectural level to deal with the faults that are not catered within the components. The existing component based fault tolerant architectures provide fault tolerance through either exception handling or design diversity. In this paper, we propose a fault tolerant architecture, which supports design diversity and exception handling fault tolerance strategies. The proposed fault tolerant component architecture employs special-purpose connectors called design diverse-multiple version connectors (DD-MVC). These connectors allow design diverse N-variants of COTS to run in parallel. Moreover, proposed architecture also has fault tolerant architectural level connector. The proposed architecture can be configured to adjust the tradeoff between dependability and efficiency and exhibits the ability to tolerate the anticipated and unanticipated faults effectively. The applicability of proposed architecture is demonstrated with a prototype implementation and a case study.

This article deals with the influence of face gesticulation to the face recognition algorithms. We have acquired our own database with different gestures and tried to test two face recognition tools for the reliability. We used a tool for change of face gesticulation and his impact to the face recognition.

Multimedia communication aims at transferring various forms of data, audio and video simultaneously in a single network. The applications such as videoconferencing, digital TV, multimedia teaching, distance learning and video on-demand make use of multimedia network and communication technologies to provide quality of service (QoS). With the wide variety of different real time system applications we need specific software for those specific real time systems that will meet the requirements of an application. In this paper, we propose the design and development procedures for real time systems using component based methodology. It starts with the requirement analysis of a real time system and continues to provide the functional model of the system and also the environmental design as well. As more and more functions or components needed to be added in designing a software system a modularized and systematic approach becomes not an option. Hence this paper proposes a systematic and procedural approach that will help to build a more reliable and suitable software architecture. This paper also includes a case study – a Multimedia Real time conferencing system, whose aim is to provide a brief demonstration of how to apply the architecture and notations that are presented in this paper.

In order to construct the most suitable embedded software development environment, we design and implements the Retargetable Tool Suite for Embedded Software(RTS-ES) composed of target code generator, low power/energy optimizer, system simulator and debugger through the proposed Embedded Processor Description Language(EPDL).
