Trip is an important part of people's lives. We need to obtain interesting location information quickly and conveniently from the huge amount of information. The existing data source of geographic locations can be divided into two categories. The one is users' information that we can utilize to deeply understand their trajectories, the other one is the characteristics and attributes of geographic...
Chronic hepatitis B is a stubborn disease afflicting mankind. Interferon alpha treatment is one of available antiviral options of treating chronic hepatitis B at present. However, the expensive treatment costs and side effects greatly hindered its application. It is useful in practice to patients suffering from hepatitis B that giving the analysis before treatment and predicting the possible effect...
Object categorization plays an important role in computer vision, semantic based image content understanding, and image retrieval. Wavelet packet transform provides a very good observation for the images by sub-band filtering. Different objects have distinctive characteristics in the sub-bands of wavelet packets, which should be discriminative for objects classification. In this paper, an object categorization...
Intrusion detection is an efficient method to detect the malicious node in the MANET. This paper presents the improvements of the existing data analysis and pattern-matching algorithm based active set, which develop a more effective BER.
Driving fatigue detection is a key technique in vehicle active safety. In this paper, a practical driver fatigue detection algorithm is proposed, it employs sequential detection and temporal tracking to detect human face, which combines the superiorities of both Adaboost and mean-shift algorithm; a morphologic filter method is given to localize the pair of eyes in the detected face area. Then multiple...
Tension feed-forward control method based on filament deform is presented in terms of filament tension generation theory. Tension control integrated system of six-axis filament winding machine is set up. Through motion analysis to non-geodesic windings for revolution object and control of resin's temperature, the equation of filament tension according to extension length is established, thus improves...
Object-oriented framework is increasingly recognized as an efficient reuse mechanism in software development, but it is still difficult to design for framework designer and instantiate for application developer. This is due to the lack of framework specific modeling language and modeling tools. We propose a feature-oriented framework model language (FOFML) to model framework following the MDA approach...
Orthogonal frequency division multiplexing (OFDM) is an attractive modulation candidate for cognitive radio networks. This paper focuses on the subcarrier and power allocation for OFDM-based cognitive radio network. Our objective is to maximize secondary user's transmission rate by adjusting its power resource under the constraint of primary user's tolerable interference limit. First, we proposed...
Quantile regression can be used for some biostatistical research as the first choice. But direct applications are often hampered by the problem of quantile regression planes' crossing in finite sample cases. After research, the Box-Cox transformation is used to avoid the crossing problem. Integrating Box-Cox transformation with quantile regression, we suggest a new method. And the fitting of salmon...
