In order to implement cognitive radio (CR) in the future, the choice of a physical layer data transmission scheme is very important. In this paper, we compare two agile transmission schemes employed for CR networks: Single Carrier Frequency Division Multiple Access (SC-FDMA) and non-contiguous OFDM (NC-OFDM). First, a qualitative comparison is provided by analyzing the advantages and disadvantages of each scheme. Then the performances of both schemes are compared by simulation. The simulation results and corresponding analyses demonstrate that the performance of SC-FDMA is generally better than NC-OFDM in CR networks. Therefore, SC-FDMA can be a promising alternative to NC-OFDM for CR networks.

In order to solve the existing curriculum resource issues on the internet, such as lack of semantic, simple resource structure, the ineffective share of curriculum resources. Protégé tools are used to construct domain ontology of curriculum, and to put forward a curriculum resource management framework based on ontology. In this framework, the curriculum ontology is used to describe the curriculum resource, so as to make curriculum resources achieve the shared and mutually operation on the layer of semantic. Besides, with the help of the development tool “Jena”, ontology storage and query are supported, to ensure the quick finding of learning resources and to promote effective learning...

This paper presents an intelligent generalized predictive controller (GPC) based on particle swarm optimization (PSO) for linear or nonlinear process with constraints. We propose several constraints for the plants from the engineering point of view and the cost function is also simplified. No complicated mathematics is used which originated from the characteristics of PSO. This method is easy to be used to control the plants with linear or/and nonlinear constraints. Numerical simulations are used to show the performance of this control technique for linear and nonlinear processes, respectively. In the first simulation, the control signal is computed based on an adaptive linear model. In the second simulation, the proposed method is based on a fixed neural network model for a nonlinear plant. Both of them show that the proposed control scheme can guarantee a good control performance.

The DNS server will often be attacked through various means, which will lead to our DNS server's low efficiency or even make the DNS server not to provide service of DNS analysis normally and correctly. DNS detection is just to detect whether these accusations happen or not in time. There are many methods for anomaly detection of DNS server, for example, the method based on similarity, the method based on entropy and so on. We will research the combination of the two methods and then realize it. This will improve the monitoring effeciency.

This article selects the patent number as an innovation performance alternative variable to test the impact of technology mergers on the innovative performance in high-tech industries listed companies empirically by using the panel data negative binomial regression model. It shows that non-technical merger acquisition has no significant influence on the innovation achievements for a company; the absolute size of the acquired knowledge base makes a positive impact on the innovative performance of the acquiring firm; while the relative size of the acquired knowledge base has a negative effect on the innovative performance of the acquiring firm. These results provide the empirical basis of technology mergers & acquisitions for the listed company.
