Abstract: The concept of Internet of Things (IoT) is opening new horizons in systems intelligence, where physical objects (embedded with sensory, identification and networking capabilities) can interact with other objects through the global infrastructure of wireless/wired Internet. These systems can be monitored and controlled by filtering and processing collected data. Such intelligent design will naturally result in efficient and cost effective systems. The concept of IOT and the architecture of IOT are discussed. The key technologies of IOT, including Radio Frequency Identification technology, Electronic Product Code technology are analyzed. The framework of digital agriculture application based on IOT is proposed.

Abstract: In this paper, a web-based grid computing model for total transfer capability (TTC) with transient stability (TS) constrains is proposed. The grid computing model is designed in a heterogeneous web environment to implement the cross-platform application. A kind of power system analysis software package is integrated as the computing engine during computation. Finally, application example with a real-sized Chinese power system demonstrates the validity of the proposed model.

Abstract: Grey system theory has been widely used to forecast the economic data that are often highly nonlinear, irregular and non-stationary. Many models based on grey system theory could adapt to various economic time series data. However, some of these models didnt consider the impact of the model parameters, or only considered a simple change of the model parameters for the prediction. In this paper, we proposed the PSO based GM (1, 1) model using the optimized parameters in order to improve the forecasting accuracy. The experiment shows that PSO based GM (1, 1) gets much better forecasting accuracy compared with other widely used grey models on the actual chaotic economic data.

Abstract: Firstly, based on the characters of the modern storage system, the typical model was established. Secondly, the inventory modes in random and in sequence were studied by simulation using Flexsim software. Finally, the comparison and analysis between the two modes were carried out. The analysis results show that he efficiency under inventory mode in sequence is much higher than which under the mode in random.

Abstract: Online learning is more and more popular in colleges in recent years, but it still remains at a budding stage of its development. It needs more adjustment to meet the students requirements. So firstly, we should get more feedback or insight on how the students perceive and suggestions to online courses. By analyzing the problems with online learning, and basing on the literature review, this article gives the finding point and conclusion. And that is supposed to help both the instructors and the administrators decide if the school should continue their online learning programs.

Abstract: The development of the internet of things has been elevated to the height of the national strategy, and especially causes the public attention of IT circles. But the internet of things is inseparable from its technical platform, especially the support from cloud computing. The paper starts from the system structure of the internet of things, and discusses the architecture and implementation strategies of the internet of things platform.

Abstract: In cloud computing era, establishing a unified, open, flexible education informatization platform has significant influence in realizing resource sharing and narrowing education informatization gap. This paper presents the advantage of cloud computing and problems existing in the construction of teaching resource platform, puts forward exploiting and constructing teaching resource platform based on cloud computing, and analyzes the application function of cloud service.

Abstract: The development of information technology brings opportunities to the government and enterprises, but it also raises new requirements and contents on the operation of each interior and the reorganization of the departments. So promoting the organic integration of e-commerce and e-government becomes a research hotspot.

Abstract: The massive data must be captured and transferred in network forensics, Jpcap has provided convenient method for capturing and transferring network data. After capturing and filtering the network data packet, network forensics based on Jpcap analyzes protocol to primary data, and the current user behavior is judged legal or not through match results of user behavior and the crime characteristic. In order to guarantee evidence primitiveness, integrity and legal efficiency, the primary data is transferred by encryption. Simulation results show that the system can reappear the criminality completely, such as SYN flood and ARP deception, and can distinguish some new crimes.

Abstract: This paper presents a certain universal applicability entity coding standards and improved distributed hash table based on the specification developed a resource addressing system for the Internet of Things.
