Precision agriculture is a data-driven farming practice that uses intra-and inter-field information to optimize farming operations. The "brain" of precision agriculture is a decision support system (DSS) that acquires data from various sources, analyzes them, and recommends actions to farmers. Recently cloud computing has been used to improve the scalability and reliability of a DSS. Cloud-based...
This paper discusses the data description and organization of HGML, the data exchange standards of G/S model. Proposed the description of spatial data to show and the description of spatial data organization to solve scheduling, exchange and display problems in G/S model G-side and organization, storage and management problems in G/S model S-side. Also, described the geometric model and feature model...
Recent technology advances in information technology and other engineering fields provide new opportunities for research and practices in precision agriculture. Using these technologies, field operators can collect voluminous data from a heterogeneous network of devices that provides real-time and multiple-factor measurement of field conditions with much finer granularity. A major challenge in precision...
In the process of bridge structural health monitoring, the parameters monitored by sensors includes strain, vibration, distortion, cable tension etc.. Classification of each parameter can reflect the change of bridge structural health to some extent. According to feature of parameter data, solving methods, namely, improved single-view cooperative-training semi-supervised learning method and multi-view...
Text visualization becomes an increasingly more important research topic as the need to understand massive-scale textual information is proven to be imperative for many people and businesses. However, it is still very challenging to design effective visual metaphors to represent large corpora of text due to the unstructured and high-dimensional nature of text. In this paper, we propose a data model...
The gap between informal models used in a UML environment and formal verifications and proofs in academic research prevents UML from valid and efficient application. In this paper, we propose an approach to bridge the gap between UML class diagram and situation calculus via our formal verification tool, UCVSC (UML class diagram online verification based on situation calculus). UML class diagram describes...
This paper is presented based on paper and recent fruits gained by authors. The research background of a service oriented infrastructure for networkitized M&S, namely simulation grid, is firstly concisely introduced, then combined with authors' recent research on virtualization technology being applied to simulation grid, the phased research achievements of simulation grid are introduced in detail,...
