Land surface albedo is a critical variable used in many climate and environmental applications. The multispectral Advanced Baseline Imager (ABI) onboard the next generation geostationary satellites (GOES-R series, first launched in Nov. 2016) offers high temporal and medium spatial resolution observations, which can be used for monitoring diurnal variation of surface albedo. In this paper, we applied...
The layout of High-speed rail network determines its performance of the flexibility, connectivity and reliability. Based on complex network theory, this paper constructs Chinese high-speed rail networks(CHSRN) at three periods, and analyzes their complex properties. Using a comprehensive evaluation index combined with degree and betweenness of nodes to discover the important stations, this paper simulates...
This paper focuses on the production scheduling problem in a rotor workshop. The scheduling problem is formulated as a reentrant hybrid flow shop problem with non-identical machines in parallel. Some heuristics are developed to solve the problem. The proposed algorithms are compared through various instances that are generated based on real operations in the workshop. Experimental result also reveals...
Identifying the consumption patterns of electric customers and grouping them to classes according to their load characteristics can be very meaningful for power supply and demand side management in smart grid. Previously, tariff structures are mainly based on the type of activity. However, the type of activity and electrical behavior of the customer have poor relationship. Using clustering techniques...
Technology plays an increasingly important role in today's enterprise competition. Technology mergers and acquisitions (Tech M&A), as an effective way to acquire external technology resources rapidly, have attracted attention from researchers because of their potential realization of value through synergy. A big challenge that faces corporate managers and government policy makers is how to identify...
Aiming at the subjectivity and random problems existing in traditional evaluation and selection processes of supermarket fresh goods suppliers, and combined with the perishable and vulnerable characteristics and the current situation and development trend of supermarket fresh food, the paper constructed the ladder type evaluation framework by using SWOT analysis method, which is used to study the...
Considering the development situation of each object in different time interval in the dynamic evaluation problem, we provide a method with the feature of reward and punishment. In this method, the evaluation information participates in evaluation in the form of a whole vector. Then the timing weights are determined by the TOPSIS method, which can express the purpose of reward and punishment. Based...
Based on the problems in the Chinese university architecture, after saw about and think about, at the view of architecture and pedagogy, the article bring a pattern of Chinese universities and discussed two issues of the pattern of Chinese university architecture study: methods of the research and contents of the research.
In order to improve the performance of Cement-stabilized Macadam, based on the principle of stage filling theory and adopting vibration test method, Multilevel Dense Built-in Grading structure gradation (MG gradation) of Cement-stabilized Macadam is determined. Some tests such as indoor vibration compaction test, strength test in the mechanics and CBR Granular Flow numerical simulation technology...
The most common method of tender evaluation for engineering projects was traditional comprehensive scoring or the lowest tender price method after evaluation, and AHP or fuzzy comprehensive judgment was also used for tender evaluation, but all these methods had several defects such as having highly subjectivity, lacking analysis of evaluation indexes and not reflecting weaknesses of tenders and causes...
According to the characters of the third-party logistics enterprise, the article constructs an index system of performance evaluation that consists of four classification criteria which includes the financial performance, operational procedures, learning and innovation and customer relationship management. The index weights are determined by combining analytic hierarchy process (AHP) method and principal...
The most common method of tender evaluation for engineering projects was traditional comprehensive scoring, and analytic hierarchy process or fuzzy comprehensive judgment was also used for tender evaluation, but all these methods had the defect of having highly subjectivity. Although the traditional DEA model can exclude bias caused by human factors, it can't distinguish efficient decision-making...
Statistical analysis of massive data is becoming indispensable to science, commerce, and society today. Such analysis requires efficient, flexible storage support and special optimization techniques. In this demo, we present RIOT (R with I/O Transparency), a system that extends R, a popular computing environment for statistical data analysis. RIOT makes R programs I/O-efficient in a way transparent...
Transfer function plays an important role in volume rendering. Multi-dimension transfer function can achieve high rendering quality, but suffer from troublesome user specifications. In order to reduce the complexity of manipulations, a transfer function design method based on dimension reduction model is proposed in this paper. The idea of dimension reduction model is to integrate several data features...
Based on a survey on evaluation index system of network culture security (NCS), with an empirical analysis, this paper classifies the varied information concerning NCS and establishes the evaluation index system of NCS. It can provide evidences for establishing and progressing the laws and regulations of system of NCS, and for studying and developing the safeguard structure and the systematic platform...
In this paper, a family of automata for weak factor recognition named weak factor automaton (WFA) is introduced. WFAs can at least recognize the factors of a word and have similar properties of the factor oracle. WFAs are not always acyclic and the acyclic WFA is equivalent to the factor oracle with redundant edges. Based on the same approach, a new weight automaton for precise full-text index is...
The administrative decision-making is very important for the government. However, the decision-making procedure of the government was low-efficiency in the past. Based on the multi-agent technology, an administrative decision-making support system is proposed in this study, which improves the decision-making effectiveness and efficiency through the distributed collaboration of different decision-making...
