A well understanding of topography effect on the forest reflectance is critical for biophysical parameters retrieval over rugged area. In this paper, a new hybrid bidirectional reflectance distribution function (BRDF) model coupled the geometric optical mutual shadowing (GOMS) and scattering from arbitrarily inclined leaves (SAIL) models with topography consideration (GOSAILT) for sloping forest was...
In this study, we evaluated the effect of material properties for addictive direction manufacturing by Three-dimensional printing (3DP). The fused deposition modeling (FDM) is one of the most commonly employed 3DP methods. Tensile tests at ordinary temperatures were carried out on materials consisting of polylactide. Addictive direction of the tension specimen with different addictive direction was...
Workflows provide a popular means for preserving scientific methods by explicitly encoding their process. However, some of them are subject to a decay in their ability to be re-executed or reproduce the same results over time, largely due to the volatility of the resources required for workflow executions. This paper provides an analysis of the root causes of workflow decay based on an empirical study...
Using research on the quality of satisfaction regarding Ningxia agriculture information service (AIS), this paper analyzes and summarizes the disparity between the consumers of the information service (the demand side) and the providers of the information service (the service side) using the demand-service gap model, the SERVQUAL assessment method and grey fuzzy correlation theories. From this, an...
BT model is a new kind of financing model emerged in the public project. The critical node of BT project is to coordinate the different demands of each stakeholder. Based on the stakeholder theories, firstly the stakeholders of the BT project are defined and classified in this paper. Then the benefits demands of the core stakeholders are analyzed and the reasons of the confliction are illustrated...
Vegetation background research, especially the basic work of ecological environment construction in arid area of northwest China has become much more significantly gradually. Potential vegetation is the most stable and mature climax vegetation type which achieves the balance state finally without human interference, and it can also be used to rehabilitate and reconstruct of vegetation regionally....
With the rapid development of economy, China's appetite for electricity is getting larger and larger. The current coal-dominated electricity matrix has caused severe environmental degradation and energy shortage. China should make use of renewable energy resources to help transform its economy into a low-carbon one. Constructing parabolic trough solar thermal power (PTSTP) plants in China, will change...
The tradition contract net protocol is not restricted on the promise of agent in the collaborative process. The agents are repeat negotiated result the efficiency of collaborative is low. In the design process of enterprise collaborative, through the preselection in advance of organization norm, there are decrease the cooperation in the contract net protocol. It improves the multiagent collaborative...
This paper describes a method of building a medical ontology prototype in Chinese. During the procedure, we explored the following questions, which are crucial for the task of ontology engineering: (1) are there some more computer-understandable knowledge description models? We proposed a structural and fine-grained knowledge description model called concept-based description model (CBD) to describe...
Coal is a key of basic energy in China, and it supports the rapid development of the national economy. In the coming period, coal will also play the very important role in base energy. Therefore, the prediction of coal demand is particularly important in future. In this paper, the double hidden layers BP neural network is established and simulated based on Matlab technology. After testing actual data,...
