Modeling of systems, for example, communication systems, involves identification of their basic components and interrelationships. This paper proposes a model of ethical systems based on the notion of flow. The flow of ethical rules, for example, ought not lie, is conceptualized to trigger the flow/blockage of other flows such as information flow. In this scheme different types of mechanisms can be identified for classifying systems. Lying is used as an example of an ethical issue to illustrate the proposed approach. Read More Read Less

To solve the problem, this paper proposes an improved blind digital watermarking algorithm for images based on the combination of Discrete Wavelet Transform (DWT) decomposition and Particle Swarm Optimization (PSO). For protecting the copyright information of a digital image, the watermark preprocessed with an affine scrambling is embedded in the vertical subband ( ) coefficients in wavelet domain. Furthermore, the proposed algorithm based on PSO is performed to train scaling factors to accomplish maximum the watermark strength while decrease the visual distortion. Simulation results demonstrate the proposed watermarking procedure has the remarkable performance in robustness to various attacks and the superiority of the proposed scheme. Read More Read Less

In today’s world, importance of biometric studies is increasing day by day. Biometric face recognition study is the most widely used method in the legal environment. Commonly, face image uses in all identification (IDs, driver’s license, passport, etc.). In particularly, to improve the social security of city life, automatic face detection and face recognition systems are needed and there is a lot of study for this purpose. So we developed a template matching method and performed to obtain face image from entrance picture. Average face mask was obtained using hundred people normalized face image. Face mask has been applied to entrance picture and the shortest distance part of the entrance picture matched the face mask. When applying of the face mask to entrance picture, corner detection and difference matrix methods performed together improving the achievement. In additionally, entrance picture background, luminance conditions have the negative effect that has been tried to choose simple background entrance picture. Realized in our study could be based for further study on face detection-face identification. In addition, the system could be developing further using the artificial intelligence (AI) methods.

Software projects are important part into almost every business application. It is quality, efficiency and effectiveness of these applications will determine the failure or success of many business solutions. Over the past few decades, software projects often failed to come up to user expectations, by it were commonly late delivered, and mostly ran over the set budget. Indeed, much of this still holds true today, and it has alerted the development process. The literature analysis and surveys showed that there is a need for a framework to mange the software project, where software projects as the literature mentioned always run over time and budget. So in this study, we proposed a theoretical framework to deal with previous issues. This framework considers the following issues: technical factors, organizational factors, people factors, and culture factors and their influence on software project success. Also this framework explains the relationship between previous factors and risk management and change management. The framework shows how can software project success factors be controlled and monitored. A detailed description of the framework will also be highlighted.. Read More Read Less

Abstract In this paper, we present a new model for semantic description of Web services called CYASA4WSDL (stands for Capacity-driven Yet Another Semantic Annotation for Web Services Description Language, CYASA for short). CYASA is strongly inspired from Capacity-driven Web Services Description Language (CWSDL for short) and Yet Another Semantic Annotation (YASA for short) description models. We also present a discovery algorithm... In this paper, we present a new model for semantic description of Web services called CYASA4WSDL (stands for Capacity-driven Yet Another Semantic Annotation for Web Services Description Language, CYASA for short). CYASA is strongly inspired from Capacity-driven Web Services Description Language (CWSDL for short) and Yet Another Semantic Annotation (YASA for short) description models. We also present a discovery algorithm for such Web services. We show throughout this paper how YASA4WSDL Web services are matched basing on with reference to the specificities of YASA4WSDL descriptions. This algorithm was implemented in CYASA-M, a new Web service matchmaker. CYASA-M is evaluated and compared versus YASA matchmaker to highlight its contribution. Read More Read Less
