An approach of sleep stage classification based on Time-Frequency analysis and Random Forest (TFRF) on a single channel is presented in the paper. Before classifying sleep stages, representative features are extracted by feature extraction method, such as FFT in the frequency domain of EEG signal and...

Intelligent building and environment sensing technology are becoming more and more popular. Many office buildings use IoT to set up environment collection sensors to collect environmental information, however the way of evacuation inside still using traditional evacuation guidance equipment. Therefore,...

One of the most significant achievements in modern healthcare systems is the release of the IEEE 11073 family of standards, which formalize the compatibility and interoperability of medical devices and external computer systems. However, IEEE 11073 does not define standards and modes of communication...

Grid technology as a new information technology enables resource sharing and the "two fog" eliminating in the field of equipment support. Firstly, the demands of equipment support grid design were analyzed. Besides, the three popular grid architectures were outlined. Finally, the equipment support grid...

The information service industry is regarded as one of the new poles of growth for China's economy with much more effective productivity of factors and it is overall most competitive in the Yangtze River Delta region. In this paper, the quantitative analysis of total factor productivity (TFP) growth...

In passive ultra-high frequency (UHF) radio frequency identification (RFID) system, tag collision is generally resolved on a medium access control (MAC) layer. However, the collided signals are in fact recovered on a cross-physical (PHY)-MAC layer to enhance identification efficiency. This paper adopts...

Wireless Sensor nodes are small, low power consumption nodes which are basically used for sensing, transmitting and receiving the target values to specify nodes. Basically, we deploy nodes to collect information about specific region and to know about current and future results. Wireless Sensor Networks...

The transmission capacity of ultra-high voltage direct current (UHVDC) transmission system is huge. Once a fault occurs, it will bring tremendous impact on the operation of the power grid, bring about a number of problems such as power flow overload, insufficient reserve, and frequency drop, and induce...

The near-field electromagnetic ranging (NFER) technology exploits the near-field phase behavior of low frequency signals to measure the distance and can provide better ranging performance than the high frequency signal based methods in the cluttered environments. However, the currently existing NFER...

Nowadays, with the increasing number of protein sequences all over the world, more and more people are paying their attention to predicting protein subcellular location. Since wet experiment is costly and time-consuming, the automatic computational methods are urgent. In this paper, we propose a variant...

Chinese calligraphy synthesis is important meaningful to protect non-heritage cultural and augmented reality. In this paper, we proposed an algorithm of Chinese Calligraphy synthesis based on examples. First, we construct a stroke library represented by vector. Second, we obtain the trajectory of character...

In order to improve the navigation precision of the classical sandia inertial terrain aided navigation (SITAN), replacing kalman filter (KF) with particle filter (PF) for nonlinear system, this paper modifies and compensates inertial navigation system (INS) by terrain matching. Moreover, this paper proposes...

In recent years, along with the improvement of population quality and the advancement of the rule of law society, the market for legal services in the middle and low-end markets has continued to expand, and legal advice has become widespread in daily life. In the process of legal services, the legal...

Generalized Stewart Platform is the extended form of Stewart platform of parallel linkages, which is two rigid bodies connected with six constraints. The classification of direct kinematics to 3D3A generalized Stewart platform with equilateral triangle platforms based on symbolic computation is presented....
