In recent years, the finite difference time domain (FDTD) method has been prevailed in the simulation of metamaterials widely. As the FDTD method can be suitable for the parallel computing, we apply this method to the Fermi-architecture Graphic Process Units (GPUs) to calculate the electromagnetic simulation of double negative materials in this paper. Finally, both theory analysis and results of simulated...
The Physically-Asynchronous Logically-Synchronous (PALS) system is a recently proposed architectural pattern for cyber-physical systems. It guarantees a logically synchronous design abstraction for real-time distributed computations. In this work, we develop a new middleware, called PALSware, to support an efficient and robust implementation of the PALS system and its extensions. PALSware guarantees...
The development of industry informationization and electronic commerce (e-commerce) promote the emergence of electronic market (e-market). One called electronic exchange (e-exchange) is a typical business model. It requires a higher security level for the business operating system. This paper systematically studies the e-exchange security problems from the view of e-commerce security, analyzes the...
This paper analyzes the characteristics of geological spatial information sharing at first. In order to break the current ldquoinformation islandrdquo and implement spatial information sharing among virtual organizations, the concept of China geological spatial information grid is proposed. Focusing on the core techniques of grid virtual and collaborative issues, this paper discusses the framework...
Knowledge management (KM) is a new problem for e- commerce and enterprise application integration (EAI) , and it has become one of the research front and hotspots in management science and engineering. In this paper, the requirements and key problems of e-commerce application oriented enterprise KM are discussed, a enterprise information portal(EIP) based KM solution is presented, the key techniques...
