Abstract: To improve effectively the performance on speech emotion recognition, it is needed to perform nonlinear dimensionality reduction for speech feature data lying on a nonlinear manifold embedded in high-dimensional acoustic space. This paper proposes an improved SLLE algorithm, which enhances the discriminating power of low-dimensional embedded data and possesses the optimal generalization ability. The proposed algorithm is used to conduct nonlinear dimensionality reduction for 48-dimensional speech emotional feature data including prosody so as to recognize three emotions including anger, joy and neutral. Experimental results on the natural speech emotional database demonstrate that the proposed algorithm obtains the highest accuracy of 90.97% with only less 9 embedded features, making 11.64% improvement over SLLE algorithm.

Abstract: To make the inner Mongolia National cinema line company to expand the low-cost movie channel benefitting civilian, take better advantage of the company's movie integration and issue, bear the spread and services of films in the whole inner Mongolia Autonomous Region, in this paper, we design and implement the cloud system of inner Mongolia National cinema line, take intelligent digital television operating system under the cloud technique as carrying and transmission tool, broadcast a front-end frequency point through the cable digital television network in the total region, broadcast the digital and cultural content, such as high-definition movies, digital books, party member education , technical training, newspapers, magazines, government information and convenience information, to each neighborhood and community, all levels of schools, factories and business units in the whole region, build the cloud cinema of multi-functional digital cinema hall whose contents are unified, with truly unified management, unified propaganda, unified arranging videos, service on demand, promote the industrial development of national digital culture industry, expand new channels of the national film show, serve the overwhelming majority of community residents.

Abstract: In the existing digital TV platform based on direct broadcast satellite, using the idle repeater resources, digital TV intelligent operating system and the core technology of middleware can present multiple functions such as broadcast TV, cable TV network etc. in one terminal without increasing the cost of existing satellite receiving terminal, realizing a variety of digital service like satellite TV channels, local channels, movies pushing Well-being community, health care, culture sharing, government affairs openness, television, newspapers and magazines. At the same time it can be transmitted to the edge server of Internet, the front of cable TV network and other network environment to realize the integration of three kinds of networks, which creates a kind of public digital cultural information service system with less investment, multiple functions, wide coverage, fast transmission speed, resource sharing, safe and controllable.

Abstract: Spatial structure of landscape ecology is composed by different ecosystems, the interaction function and dynamics. It is to the entire landscape as the research object, emphasizing the interaction between the protection and management of large areas of population ecology, management of environmental resources and human activities spatial heterogeneity of the maintenance and development, ecosystem and its components on the landscape impact. This paper presents several models of several computer-aided digital design environments, and the depth of the concrete application of various models.

Abstract: In this paper, to meet the security need of electronic records under the digital office environment, technological requirement of the security of electronic records is analyzed, and the security model of electronic records based on IPSec protocol is designed and tested under Windows 2000 Server system. As is showed in the test result, this model can secure the electronic records based on digital office environment.

Abstract: DICOM is the international standard for the digital imaging communication in medicine. This paper introduces the development of DICOM and analyzes the communication process based on DICOM protocol. Besides, the communication between store SCP and store SCU was designed and implemented.

Abstract: Along with the development of information technology, archives information has developed from original paper archives to current digital archives, electronic photos, electronic drawings etc., and the utilization of archives has also achieved computer search and online inquiry. The development of various modern information stealing technologies has brought potential threat to the security of network archival information, especially some military scientific research archives, student archives etc., which are not only involved with the normal operation and development of schools, but also with official secrets. Therefore, establishing the archives security system of colleges and universities has become the priority among priorities in the archives work of colleges and universities. This article starts from the current status of the archives security system construction of colleges and universities, analyzing the apparent features of the technology of the Internet of Things in information technology, and then raising the specific application measures of the technology of the Internet of Things in archives security system construction of colleges and universities, making suggestions on the archives security system construction of colleges and universities.

Abstract: This paper develops an improved hybrid optimization algorithm based on particle swarm optimization (PSO) and a genetic algorithm (GA). First, the population is evolved over a certain number of generations by PSO and the best M particles are retained, with the remaining particles excluded. Second, new individuals are generated by implementing selection, crossover and mutation GA operators for the best M particles. Finally, the new individuals are combined with the best M particles to form new a population for the next generation. The algorithm can exchange information several times during evolution so that the complement of two algorithms can be more fully exploited. The proposed method is applied to fifteen benchmark optimization problems and the results obtained show an improvement over published methods. The impact of M on algorithm performance is also discussed.

Simulation results show that the discrete wavelet transform algorithm optimization wavelet transform algorithm than the digital signal modulation recognition applications to identify errors in the proposed smaller, more accuracy.

Abstract: An objective measurement to evaluate sleep-wake state was studied based on the hidden information among ECG and pulse signals that might offer insights into the nature of sleep. Pulse transit time (PTT) and Wavelet entropy (WE) were computed for twenty sets data which come from self-designed experiments to distinguish the two different states of mental. A significant increase of PTT and decrease of WE ware correlated with the state of drowsiness, and both feature t-test results were p<0.01, thus showing that these features have significant differences between awake and sleepy state. Furthermore, the two characteristics can be recommended as objective indicators for distinguishing the human mental states.
