The paper addresses the finite time stability analysis of continuous-time LTI systems. Based on its definition, the necessary and sufficient condition can be derived easily. Verification of the condition is almost impossible because an infinite numbers of checking points are required. Therefore, by using the well-known Bellman-Gronwall inequality, a set of more efficient and practical LMI-based conditions for solving the problem is obtained. In viewing of relaxing the conservativeness of the LMIs, the concept of partitioning the time interval of finite time stability is exploited and a new set of less conservative LMIs are proposed. Moreover, a theoretical proof to show the reduction of conservativeness is given. Simple examples are used to illustrate the improvement of the proposed approach.

With the popularity of mobile Internet and the rapid development of data mining, we can collect users' behavior trajectory and find regularity from a large amount of data. In this paper, we use the WiCloud system to obtain students' trajectory information, and propose a spatial-temporal clustering method based on K-means algorithm, which clusters students into three types: study-oriented, enclosed type and active type. A method for analyzing students' learning atmosphere based on trajectory data is also proposed, with which we get different trends of campus students' learning atmosphere in different time periods among different types of users.

Onomatopoeia is a generic name for onomatopoeia and mimetic words. Using onomatopoeia can express the behavior and state of things in more detail, widening the range of communication. However, learning onomatopoeia has been a difficult task for Japanese learners. There are several existing studies aiming at a support with onomatopoeia learning, while no platform is available to help learners find similar onomatopoeia based on different criteria. In this paper, we have developed a system that proposes similar onomatopoeia for an input in three manners: one with a dictionary, and two based on statistics. A comparison with an existing system shows the effectiveness of our approach and exposes some future issues.

There are many problems in the current massive open courses (MOOC) platform construction, such as high cost, high energy consumption, long construction period and poor reusability. In order to solve the above problems, a new platform construction schema of MOOC+Small Private Online Course (SPOC) based on Internet Data Center(IDC) is proposed. This platform can help users to quickly create their own SPOC, which has high modularization, reliability, scalability, and reusability.

Blockchain is considered as the important technological innovation behind Bitcoin system. It facilitates the transaction payment process by creating a decentralized, general ledger to improve regulatory capacity and remove unnecessary intermediaries. At present, the blockchain technology has been employed in the financial industry for a wide range of experimental application and exploration. In this paper, we firstly analyze the principle architecture and the technical characteristics of blockchain. Then its current research achievements and application scenarios are introduced. Finally, the application of blockchain in China Foreign Exchange Trade System is designed and explored. Combining with the credit matching trading system X-Swap, an inter-bank application based on the blockchain technology is implemented.

At present, radio frequency identification technology has been widely used in many fields, such as data acquisition, transportation, logistics management and so on. However, the collision problem in RFID technology seriously affects the performance of RFID system. Aimed at the shortcomings of search times and traffic by the traditional binary search algorithm, this paper propose an improved binary search algorithm based on the combination of dynamic binary search algorithm and backward binary search algorithm. Experimental results show that the improved algorithm greatly reduces search times and the amount of data transmission, thereby improving the recognition efficiency.

In order to study the theory and characteristics of the mechanical drive system fault in the current signal of the wind turbine generator better, the fault simulation experimental platform of double fed wind generator drive gear is used as the research object, and the simulation model of double motor torque and rotational speed coupling is established by a motor and a doubly fed wind generator according to the mathematical model of AC asynchronous motor. Moreover, a detailed simulation analysis is carried out to the situation that the experiment platform is difficult to realize or test. The results show that the fault characteristic information in generator stator current is mainly transmitted by the speed fluctuation, and due to the influence of the system inertia and the harmonic components of the rotor excitation converter, it is more difficult to identify and diagnose the fault characteristic information. Therefore, how to remove the harmonic component to improve the ability of fault feature recognition is a problem to be solved for doubly fed wind generator.

This study examines the emotion and framework effect under the different cultural backgrounds on national communication intentions. The study found that cultural background, emotions, and expression of framework information influenced to the public communication intentions by influencing behaviors; the framework effect under different emotional states of the national communication also can produce different effects. Public communicative intention in national regions affect by the social security events and treatment effect.
