Nowadays, Cloud computing is a major trend. It is a new data hosting technology that becomes very popular lately thanks to the amortization of costs induced to companies. Since this concept is still in its first stages, new security risks start to appear. This paper will set forth the major security issues in cloud computing and propound a new solution to secure data, storage in the cloud environment.
The Cloud Computing is a new concept in which dynamically scalable resources, virtualized and provided to users as a service over the Internet. It is primarily intended to meet the needs of users and allow them access to virtually unlimited resources. In fact, many researchers are motivated to develop solutions to improve performance and give users more tools to control the use of cloud computing...
The objective of this paper is to present a new profile for the design of embedded systems at the system level, appointed CoMMix Profile. This profile offers unified concepts for designing the systems level. It privileges a component-based approach based inspired by AADL (Architecture Analysis and Design Language) and as well SysML and UML-Marte standards. Modeling CoMMix system is described as an...
Nowadays, almost all organizations are using Information technology (IT) tools to manage their business. Information systems (IS) organizations involved in these areas are as diverse as system management, advertising, online sales and also maintenance and communication. IS becomes increasingly complex making it difficult to follow the complex growing demands of IT resources requirements. Cloud Computing...
The complexity of image processing algorithms using mathematical calculations grows from the nature of the image to be processed and the desired result. A hardware implementation of these algorithms for the needs of real-time and embedded systems improves performances. In this paper we present some existing approaches used for hardware systems modeling. We propose a new graphical tool for designing...
Embedded systems are becoming more complex by integrating multiple features. They require a lot of resources to improve execution performances. Their developments are a real challenge since both their complexity and their quality of service requirements. To manage this complexity, a model driven approach focuses on the design of these systems by raising the level of the specification abstraction....
In this paper we identify the requirements of a design tool for the implementation of image and video processing algorithms in hardware platforms such as FPGA or ASIC. We discussthe advantages and weaknesses of some existing design languages. Finally, we propose our solution, in compliancewith specified requirements, which intends to bypass the shortcomings of existing languages by providing a high-level...
