The increasing pervasiveness of location-acquisition technologies has enabled collection of huge amount of trajectories for almost any kind of moving objects. Discovering useful patterns from their movement behaviors can convey valuable knowledge to a variety of critical applications. In this light, we propose a novel concept, called gathering, which is a trajectory pattern modeling various group...
Aiming at the software engineering practice of undergraduate, this paper proposes a software development practice platform. This platform effectively combines teaching management with software development process management, and realizes a complete lifecycle management of software engineering practice. As well, based on event ontology, this platform constructs a knowledge base of teaching resources...
Acutely isolated rats cortical neurons were exposed to 2450MHz radio frequency (RF) magnetic field, and the characteristics of delayed rectifier potassium channel were studied using the whole-cell patch-clamp technique. The 2450MHz RF magnetic field was obtained by Agilent E5070B net analyzer and a 6dB gain omni directional antenna, and the transmitting power was 39.81mW. The experiment revealed that...
The increasing availability of GPS-embedded mobile devices has given rise to a new spectrum of location-based services, which have accumulated a huge collection of location trajectories. In practice, a large portion of these trajectories are of low-sampling-rate. For instance, the time interval between consecutive GPS points of some trajectories can be several minutes or even hours. With such a low...
Vocational Identity demonstrates the psychological features in the formation and specification of occupational choice. It also reveals the potential occupation fitness and stability of job hunters. In this paper a vocational identity model is proposed based on the framework of Dual-cycle model of self-identity. Proceeding from the applicability for practice, empirical research on the structure and...
PLC Mine poor working conditions, a serious signal interference, the analysis of interference occurs because, from the hardware, software two aspects, proposed anti-jamming countermeasures PLC, PLC control system to improve anti-interference ability and system stability.
This paper analyzed the curriculum teaching situation in the database principles of undergraduate education, summarized of a number of issues in the teaching practice. Aimed to solve these problems, and the characteristics of the course, the content of teaching, the perspectives of optimization of teaching contents and reform of teaching methods were discussed.
The seasonal fluctuation of AVI has significant impact on economic growth. Based on the methods of Directional Statistics, this paper analyzes AVI in Shaanxi Province between 2006 and 2010. Distribution types are ascertained by using von Mises distribution tests, which is submitting to bimodal von Mises distributions. Correspondingly, the result indicated that the AVI in Shaanxi Province has a character...
This paper presents a novel quantum-inspired algorithm(QGA) for the heavily constrained university scheduling problems(CUSP). The CUSP is a common problem for all institutions of higher education. It has been proved a NP problems. We propose a solving of CUSP based on the use of quantum-inspired algorithms. In the QGA, Q-bits based representation is employed by updating operator of quantum gate which...
This paper puts forward an algorithm named CFE (co-occurrence frequency emphasized) for new concept selection which based on word co-occurrence, it has been applied to domain concept extraction. This algorithm grasps the central idea of word co-occurrence rigidly. In the process of concept extracting, the co-occurrence frequency is taken as the basis of new concept selection, and the impact of absolute...
The course timetabling problem (CTP), as a typical combinatorial optimization problem (COP), has been proved to be NP-Complete. Due to its complexity, the general genetic algorithm converges slowly and easily converges to local optima. A novel quantum-inspired evolutionary algorithms (QEA) is put forward for the CTP. The QEA uses genetic operators of Q-bit as well as updating operator of quantum gate...
