Human computer interactions (HCI) are the technologies of realizing the dialogue between human and computer in an effective way through computer input and output devices. Human performance model has an important theoretical guidance for the development of human computer interaction. Through the establishment...

Because of the lack of research on the abstraction of scenarios in the traditional method based on scenarios, and lack of an effective method to describe scenarios. In view of this, a method was proposed to describe scenarios based on refinement. First, a new scenario metamodel based on refinement relationship...

With respect to the ontology knowledge representation of refrigerator, a question answering system was designed based on ontology triple structure query. The ontology knowledge representation of refrigerator is built with representing the refrigerators’ instance, attributes and values with the subject-predicate-object...

Polarization properties of horn antenna are studied in the paper. The linear and circular polarized horns are simulated. There are four lobes in the cross-polarization pattern of linear polarized horn. And the phase of cross-polarization is changed at each bound of the quadrants. That of co-polarization,...

Schumann Resonance is the natural atmosphere noise in ELF band. The measurement and data processing are discussed in the paper. The composition of the equipment is described. SR data processing methods are detailed, including FFT method, periodogram, SVD filtering and curve fitting. The results by different...

Based on China's colleges and universities are the different types of 267136 questionnaire data, as well as acquisition simulator WeChat grabbed to nearly 2GB of data, as well as the tertiary education sector keyword data collection, as well as domestic colleges and universities to provide authoritative...

The current WPS Platform exist some limitations such as insufficient extensible ability and low concurrent requests response efficiency. Aiming at these limitations, this paper proposes a new WPS frame based on task distribution, and uses task distribution system Gearman to reconstruct the WPS process...

Due to the exponential growth of wireless devices and the rapid development of smartphone's computing and storage capabilities, interests on using smartphone to remote access and manipulate smart home facilities have been increased greatly in recent days. However, this application context requires smartphones...

This paper is concerned about the rod current of aluminum reduction cell. Daubechies12 wavelet was adapted to analyze time-frequency characteristics of anode current collected which was carried on the pretreatment, and the experimental results verified the effectiveness of the proposed scheme, compared...

Artificial Population is very useful in many application domains. In this paper, we use census data to synthesize artificial population. We define the structures of household and individual. The data patterns of census data are analyzed too. Based on these definitions and patterns, we design the algorithms...

In order to reach ubiquitous perception in Internet of things, which confusion of network deployment can’t generate when information collection, some security problems are considered in IOT, such as key management, privacy protection and data processing. A key management scheme based on Homomorphics...

Sophisticated key management schemes and protocols, whose main objective is to provide secure and reliable communication. But the design of it meets some challenges in wireless sensor networks, whose intrinsic properties make it difficult. In this paper, A lightweight and high security key management...

With the increase of mobile payment malicious applications, an accurate assessment of their safety is particularly important. In recent years, machine learning methods have achieved good results in text recognition, medical diagnosis, anomaly detection and other fields. Therefore, we consider the introduction...

The organization of the mass sports event has to be supported by the tools and technologies related to the safety engineering. These include the ICT systems that enable the real-time upload the information necessary in making decisions. The picture of the augmented reality has to be ‘superimposed’ on...
