This paper presents a new recognition algorithm for plant pathology images based on the Non-negative Matrix Factorization, the proposed algorithm is combined with optimal wavelet packet basis to recognize patterns and conduct data encoding in the internet of things oriented intelligent agricultural system. The experimental results show that the performance of the proposed recognition algorithm is far better than those of the principal component analysis and linear discriminant analysis, and the recognition rate are improved, on average, about 14.65% and 11.18% higher than the rates of the above algorithms respectively. The presented algorithm is characterized by the fast speed, high calculation accuracy and easy hardware implementation.

We report here a clinical case of phaeohyphomycosis in an 18-year-old male giant panda (Ailuropoda melanoleuca). Skin lesions on the giant panda disappeared following 2 months of treatment with ketoconazole. Three months after discontinuing the treatment, there was a clinical and mycological relapse. The disease progression was no longer responsive to ketoconazole. Microscopy and polymerase chain reaction (PCR) analysis revealed that the infection was caused by Cladosporium cladosporioides. A 4-month treatment regime with Itraconazole oral solution (700 mg per day) successfully terminated the infection.

The Grenville Front Tectonic Zone (GFTZ) is a polyphase deformation belt in the northwest of the Grenville Province which was shaped in the continent-continent-collision-induced Grenvillian Orogeny. This thesis focuses on the evolution of deformation fabrics in the GFTZ between the Sudbury Basin and French River in Ontario, Canada. Geological mapping using a new digital mapping system was conducted within this segment of the GFTZ, in its northwest vicinity in the Southern Province, and in its southeast vicinity in the Grenville Province. The new digital mapping system includes a personal digital assistant equipped with an internal GPS and a mobile GIS mapping software, and the ArcGIS software, which together worked seamlessly in the whole mapping process. Mapping in Whitefish Falls in the Southern Province enables us to identify two generations of folds in the Gowganda Formation of the Huronian Supergroup. The first generation is explained by bedding-parallel shear perhaps in a fold-and-thrust belt system in the Penokean Orogeny between 1850 and 1830 Ma. The second generation folds are km-to-tens-of-km-scale folds which compose the fold belt of the Penokean Orogeny. Mapping in the Grenville Province allows us to establish three phases of deformation which correspond respectively to a mid- to lower crustal sub-horizontal flow in a thickened crust, a regional folding during the NW-SE lithosphere extension, and a NW-SE crustal shortening and top-to-the-NW thrusting. The GFTZ underwent all three phases of deformation. Regional structural correlation and zircon dating suggest that the three phases of deformation occurred during 1079-1030 Ma, 1028-1018 Ma, and 1000-953 Ma respectively. Mylonite zones were developed at the NW margin of the GFTZ. Detailed structural analysis of deformation fabrics within and in the vicinity of the mylonite zones south of Coniston, Ontario, Canada shows that these mylonite zones were developed in the third deformation phase accompanying the development of at least one generation of folds in the GFTZ. Although kinematics of many mylonite zones has been “quantified” by various vorticity analysis methods in the literature, none of these methods is adopted here. Numerical modeling was used to investigate these methods, and it was found that current vorticity analysis methods have uncertainties too large for them to be useful.

The concept, Traffic Calming, was introduced to China nearly more than 10 years ago. However, no engineering practice emerges for a long time. As a typical small rural town for tour in Beijing, Zhaitang Town requires more attention on the beautiful site and pedestrian safety. In 2008, Beijing Mentougou Highway Sub-bureau decided to change the reconstruction of Zhaitang Avenue into a pilot engineering project of traffic calming. According with the research results of the traffic features in Zhaitang, the combination of mainly physical measures that reduce the negative effects of motor vehicle use, alter driver behavior and improve conditions for non-motorized street users were applied, such as Speed Humps, Raised Crosswalks, Raised Intersections, Speed Cushions, Roundabouts, Chicanes, Neckdowns, Center Island Narrowings, Lateral Shifts, Median Diverters, Boom Barrier, Pedestrian Refuges, and so on. After a half year observation, the before-andafter data of the first traffic calming engineering project has been achieved. The principles, methods, techniques to set traffic calming facilities resulted from the project and the outcome evaluation are described in the paper.

Based on the survey and analysis of current status of VMS systems application in China, this paper makes innovative study on the information disseminating strategies of Intelligent Motorway Fog Information Dissemination System (IMFIDS) via connected VMS, and then brings forward detailed strategies for two conditions: road opening but visibility under 200 meters and road closed down respectively. The strategies have been demonstrated in the pilot project - Huning Motorway Fog Semiautomatic Information Dissemination System.
