It is challenging to meet the reliability and timing requirements of wireless networks used in highly dynamic V2I applications. This paper analyzes the selected wireless networks path loss model in V2I scenarios and defines the applicability indicators, then describes their simulation models and analyses the PHY layer simulation results, and then tests(More)
In this paper, an effective method for automatic license plate recognition (ALPR) is proposed, on the basis of extreme learning machine (ELM). Firstly, morphological Top-Hat filtering operator is applied to do the image pre-processing. Then candidate character regions are extracted by means of maximally stable extremal region (MSER) detector. Thirdly, most(More)
The obligate biotrophic fungus Melampsora larici-populina (Mlp) causes devastating poplar foliar rust disease. In pathogens, the Hog1-type mitogen-activated protein kinase (MAPK) gene is involved in both pathogenesis and the response to various stresses, including osmotic stress. However, there are few reports on its role in M. larici-populina. In the(More)
The effects of extraction fluids from the leaf litter from different dominant tree species on the functional characteristics of the soil microbial community were studied to understand how changes in soil quality and synergism between plants and soil contribute to the process of forest succession. Leaf litter from dominant tree species at different stages of(More)
Cankered, dying seedlings of Juglans regia were observed in Shaanxi province in the northwest region of China. Neofusicoccum parvum was isolated from these cankered tissues, with the identification based on morphology and an ITS-nrDNA sequence. In order to demonstrate how cultures of N. parvum could cause the expected symptoms, artificial infection, using(More)
Multiple-Input Multiple-Output - Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is adopted to vehicular networks to increase the capacity, reliability and speed. In this paper, iterative demodulation and decoding algorithms are studied to approach the capacity of MIMO-OFDM vehicular networks. By analysing the drawbacks of the Gaussian approximation(More)
On the basis of the introduction of related concepts and theories, analyze the construction process of parallel transportation system and its application in traffic signal control system. The parallel transportation system of Tailiu road is established and applied in the estimation of effectiveness, the selection of control plan, and the development trend(More)
Customer knowledge management is one kind of management, which regards the customer knowledge as the enterprise’s core assets and the core competencies, which create and maintain the development of the enterprise. This paper mainly probes into the research of customer knowledge management from acquiring, sharing and even creating the customer(More)
