This paper proposed a newly designed model to satisfy the growing demand of three-dimensional indoor positioning services. The existing different positioning services cannot meet the demand in our daily life, and the increasingly need of three-dimensional positioning services has attracted more attention. In this paper, we implement our analysis and research via studying the evaluation results of...
With the development of China's Internet economy, the rapid rise of mobile media, the Internet has become the first entrance to the user access to information. The value of traditional media information portal is weakening. Media convergence is increasingly becoming the road of traditional media to survival and develops. The breakthrough of radio and television media points in the mobile terminal...
A gearbox is one of the components of double-fed wind turbine which owns the longest downtime and highest maintenance cost. The difficulty of failure prediction of a gearbox based on data is the practical verification of prediction methods. In this paper, a failure prediction method based on the data of vibration feature trend was proposed for a gearbox. The feature values reflecting the condition...
Existing personalized recommendation systems are facing many problems such as cold start, data sparseness and high complexity. Users' interests exist more widely and are more personalized compared with purchasing history in traditional recommendation systems. Thus, applying the interest graph in the recommendation process can make up certain shortages. This paper builds the mechanism of a user-interest-goods...
Satellite communication is widely used in meteorological forecast. Among the satellite communication technologies, advanced orbiting systems(AOS) recommendation is an excellent one proposed by Consultative Committee for Space Data Systems(CCSDS). In AOS, the error correction coding schemes commonly used are convolutional coding, Turbo coding and RS coding. Convolutional coding and Turbo coding are...
In this paper, we present a novel multi-level design method to secure encryption algorithms against DPA attack. Generally, DPA-resistant methods can be mainly divided into two levels: software and hardware. Software-based countermeasures are relatively cheaper to put in place, while hardware-based methods counteract DPA at a lower level and achieve better countermeasure effectiveness. Taking both...
Face images captured in different spectral bands are said to be heterogeneous. Although the heterogeneous face images from a same individual are significantly different in appearance, we can still achieve multi-modal patterns matching by image processing and transforming. In this paper, we propose a novel recognition algorithm based on face synthesis from NIR (near infrared) to VIS (visual light)...
In recent years, single-mode face recognition has achieved great progress under the impetus of a variety of applications, and its recognition rate can reach as high as 99%. Heterogeneous face biometrics, namely face mapping between images captured in different spectral bands, has now become a hotspot. Our paper focuses on the problem of face recognition between registered visual (VIS) images and predicted...
The traditional temporal error concealment methods are recovery-of-lost-MV based. However, in this paper a statistical pixel estimation model is established, based on which a novel temporal error concealment method is proposed. The proposed method has two advantages over the traditional methods as follows. Firstly, the correlation of the motion vector (MV) field is fully exploited to recover the lost...
