This paper addresses an optimal path problem in which the travel time within the travel network is subject to uncertainty. Many relevant works in the literature model the uncertainty using a random variable, however in many cases the underlying distribution of the uncertainty is not accurately determined and a solution obtained under a presumed distribution can perform poorly in practice. In this...
The paper proposes the diagnosis of Sleep Apnea Hypopnea Syndrome (SAHS) only using snore sound and SaO2 signals. The time-frequency characteristics of snore sound signal are extracted to locate the snore events, while SaO2 signal is used to determine whether SaO2 decreased concurrence. Therefore respiratory events can be detected definitely. Finally patient's Apnea Hypopnea Index (AHI) is calculated...
This paper makes a system research on the Animation derivatives evaluation process and methods and analyzes the main problems of design evaluation, meanwhile putting forward of constraint condition Animation derivatives evaluation system and model based on cost control and function. From three dimensions it devises nine secondary indexes and forty four triple the evaluation index system, combining...
A set of distributed continual range query requests, each defining a geographical region of interest, needs to be periodically reevaluated to provide up to date answers. Processing these continual queries efficiently and incrementally becomes important for location based services and applications. In this paper, we propose an efficient incremental method for continuous range query characterized by...
Given that the urban area is a complex ecosystem consisted of natural, societal and economic entities, urban ecosystem health evaluation is necessary for the scientific decision-making and proper ecological restoration. In this paper, the framework and methodology of urban ecosystem health evaluation based on emergy are proposed. The system of indices is developed including vigor, structure, resilience,...
High-tech industry acts as a strong radiating role in national economy. This paper builds an index system to evaluate the innovative capacity of high-tech industry after literature review. Then it applies Factor Analysis and Cluster Analysis to empirically study the innovative capacity of high-tech industry in 11 provinces and municipalities of East China, and offers proposals to solve existing inadequacies.
Tibet is one of the five largest pasturing regions of China. Grassland classification is significant for its utilization and protection, but few correlative studies have been done in Tibet due to its rugged natural conditions, which make it difficult and time-consuming to conduct extensive field measurements. The remote-sensing technique is helpful for grassland classification in such regions. In...
With the advance of the semantic Web, varying RDF data were increasingly generated, published, queried, and reused via the Web. For example, the DBpedia, a community effort to extract structured data from Wikipedia articles, broke 100 million RDF triples in its latest release. Initiated by Tim Berners-Lee,likewise, the Linking Open Data (LOD) project has published and interlinked many open licence...
The mass rapid transit system is essential both to rational utilization of the economical resource and optimization of overall arrangement of urban land use. Choice models diffusely used in China now are largely based on the certain values which fall short of the practice. In this passage, grey numbers are used to estimate the practical situation and the set pair analysis is introduced to determine...
