In this paper, a vehicle recognition algorithm based on deep convolutional neural network and compression dictionary is proposed. Firstly, the network structure of fine vehicle recognition based on convolutional neural network is introduced. Then, a vehicle recognition system based on multi-scale pyramid convolutional neural network is constructed. The contribution of different networks to the recognition results is adjusted by the adaptive fusion method that adjusts the network according to the recognition accuracy of a single network. The proportion of output in the network output of the entire multiscale network. Then, the compressed dictionary learning and the data dimension reduction are carried out using the effective block structure method combined with very sparse random projection matrix, which solves the computational complexity caused by high-dimensional features and shortens the dictionary learning time. Finally, the sparse representation classification method is used to realize vehicle type recognition. The experimental results show that the detection effect of the proposed algorithm is stable in sunny, cloudy and rainy weather, and it has strong adaptability to typical application scenarios such as occlusion and blurring, with an average recognition rate of more than 95%.

Although the research of immune-based anomaly detection technology has made some progress, there are still some defects which have not been solved, such as the loophole problem which leads to low detection rate and high false alarm rate, the exponential relationship between training cost of mature detectors and size of self-antigens. This paper proposed an intrusion detection method based on changes of antibody concentration in immune response to improve and solve existing problems of immune based anomaly detection technology. The method introduces blood relative and blood family to classify antibodies and antigens and simulate correlations between antibodies and antigens. Then, the method establishes dynamic evolution models of antigens and antibodies in intrusion detection. In addition, the method determines concentration changes of antibodies in the immune system drawing the experience of cloud model, and divides the risk levels to guide immune responses. Experimental results show that the method has better detection performance and adaptability than traditional methods.

The Internet Key Exchange (IKE) protocol is most widely used as a security key exchange protocol on the Internet. Security policies used by the IKE protocol must be configured in advance, however the complex options and manual settings cause inconvenience. This paper proposes an automatic configuration method for the IKE protocol based on X.509 certificate. Security policies are embedded in the certificate, read, and added into the IKE configuration file by a negotiation assistant module in order to achieve automatic IKE configuration. Our proposed method reduces the complexity of configuration process and improves the adaptability of the IKE protocol.

A multi-rotor Unmanned Aerial Vehicle (UAV) system is developed to solve the manhole cover detection problem for the infrastructure maintenance in the suburbs of big city. The visible light sensor is employed to collect the ground image data and a series of image processing and machine learning methods are used to detect the manhole cover. First, the image enhancement technique is employed to improve the imaging effect of visible light camera. An imaging environment perception method is used to increase the computation robustness: the blind Image Quality Evaluation Metrics (IQEMs) are used to percept the imaging environment and select the images which have a high imaging definition for the following computation. Because of its excellent processing effect the adaptive Multiple Scale Retinex (MSR) is used to enhance the imaging quality. Second, the Single Shot multi-box Detector (SSD) method is utilized to identify the manhole cover for its stable processing effect. Third, the spatial coordinate of manhole cover is also estimated from the ground image. The practical applications have verified the outdoor environment adaptability of proposed algorithm and the target detection correctness of proposed system. The detection accuracy can reach 99% and the positioning accuracy is about 0.7 meters.

Internet-based social and interactive video applications have become major constituents of the envisaged applications for next-generation multimedia networks. However, inherently dynamic network conditions, together with varying user expectations, pose many challenges for resource allocation mechanisms for such applications. Yet, in addition to addressing these challenges, service providers must also consider how to mitigate their operational costs (e.g., energy costs, equipment costs) while satisfying the end-user quality of service (QoS) expectations. This paper proposes a heuristic solution to the problem, where the energy incurred by the applications, and the monetary costs associated with the service infrastructure, are minimized while simultaneously maximizing the average end-user QoS. We evaluate the performance of the proposed solution in terms of serving probability, i.e., the likelihood of being able to allocate resources to groups of users, the computation time of the resource allocation process, and the adaptability and sensitivity to dynamic network conditions. The proposed method demonstrates improvements in serving probability of up to 27%, in comparison with greedy resource allocation schemes, and a several-orders-of-magnitude reduction in computation time, compared to the linear programming approach, which significantly reduces the service-interrupted user percentage when operating under variable network conditions.

This study was carried out in order to investigate the processing adaptability of Jeung-pyun. We used rice materals that were developed domestically for improving the utilization of rice. Six cultivars (Ilpoombyeo, Hwasungbyeo, Dasanbyeo, Daeribbyeo 1, Hyangmibyeo 1, Hyangmibyeo 2) of rice were used for making Jeung-pyun. In physicochemical properties of rice, Hwasungbyeo had the highest amylose content (20.4%) and Hyangmibyeo 2 had the lowest one(14.9%). Lipid content was 0.23%(Daeribbyeo 1)-0.43%(Ilpoombyeo), protein content was 7.94%(Ilpoombyeo) -8.43%(Dasanbyeo), and ash content was 0.15%(Hyangmibyeo 2)-1.24% (Daeribbyeo 1). In volume and specific volume of the 3 hour fermented Jeung-pyuns, Ilpoombyeo, Hwasungbyeo, Hyangmibyeo 2 were higher, but in the 7 hour fermented Jeung-pyuns, Dasanbyeo, Daeribbyeo 1, Hyangmibyeo 1 were higher, In the sensory evaluation of the test Jeung-pyuns, the overall quality of the 3 hour fermented Jeung-pyuns was not significantly different among the rice cultivars, whereas in the 7 hour fermented Jeung-pyuns Hyangmibyeo 2 had the lowest values. When the 7 hour fermented Jeung-pyuns were stored at 2$0^{\circ}C$, the hardness and brittleness of Jeung-pyuns were respectively increased, the cohesiveness was respectively decreased. The elasticity was not significantly different among the rice cultivars with storage days, and the gumminess was significantly difference between rice cultivars, respectively increasing during storage, but Hyangmibyeo 2 was the lowest, not increased. In insturmental characteristics of Jeung-pyuns, the hardness was correlated with amylose content and the brittleness and gumminess were highly correlated with the hardness.

Traditional applications are executed using the restricted resources of a single computer, do not consider contextual information, and can not support mobile users. However, ubiquitous applications provide optimal services for mobile users using the various resources of computers and the contextual information around users and devices. Thus, ubiquitous applications need to have the functionality of context awareness, user mobility and QoS adaptability. This paper design the CMQ(Context-aware, Mobility-aware, QoS-aware) middleware framework for ubiquitous applications and implement the middleware framework using Jini and Java. The implemented middleware system can process various contexts, provide the session handoff for a mobile user, and allow applications to adjust its QoS dynamically.
