The inefficiency in the use of expensive resource such as Magnetic Resonance Imaging (MRI) will lead to long delays in patient examination which has potential influence on patients care. The main purpose of this study is to improve MRI utilization and to reduce the waiting time of patients including outpatients, inpatients and emergency patients. Scheduling rules are designed on the basis of different...
Given a single index, the receiver operational characteristic (ROC) curve analysis is routinely utilized for characterizing performances in distinguishing two conditions/groups in terms of sensitivity and specificity. Given the availability of multiple data sources (referred to as multi-indices), such as multimodal neuroimaging data sets, cognitive tests, and clinical ratings and genomic data in Alzheimer's...
The definitions of intuitionistic fuzzy rough sets can usually be divided into two kinds. According to one kind, each intuitionistic fuzzy rough set is constructed by a couple of intuitionistic fuzzy sets. According to the other, each intuitionistic fuzzy rough set is constructed by a couple of fuzzy rough sets. In this paper, another kind definition is proposed that each intuitionistic fuzzy rough...
To speed up the construction of urban distribution network investment, a good way is to improve the reliability of grid power supply and the level of electric terminal safety. Electric power system is an organic whole, while urban distribution network has a large-scale investment. Under the constraint of total amount of investment, how to arrange the proportion of the investment between different...
At the temperature and pressure of reservoirs, the effect of steam saturation, foaming agent concentration, temperature and steam quality on rheological properties of foam oil system in steam flooding zone was studied, with shear rate varying from 0 to 600s-1; Meanwhile, the effect of superheated water saturation, foaming agent concentration and temperature on rheological properties of superheated...
In order to authenticate the integrity of audio aggregation, a fragile watermarking algorithm based on vector quantization has proposed which combining with Huffman coding. Put the output index into Huffman coding after obtaining the index's probability distribution by quantifying index address table. Then use the classical method of cryptography to complete zero-watermark embedding. The experimental...
This paper presents a general mechanical system reliability modeling and analysis method, which consider the correlations of failure modes. Firstly, the performance functions which mathematically represent the failure modes are linearized based on FORM (First Order Reliability Methods), and the correlation coefficient matrix of those functions is calculated. Then, the PFTA (Probabilistic Fault Tree...
The factors which influence the coal mining environment security assessment are analyzed, based on the statistical data and field survey results. The method of AHP is adopted to establish an environmental security assessment index system. Then the security management and rehabilitation measures of mine environment are proposed.
Park lake water in urban is playing an important role in urban environment and residents' life, but as a result of its characterizes including independence, slow fluidity and the use of reclaimed water and rainwater run-off as supplement water, it tends to be vulnerable to the outbreak of water bloom. However, pretreatment could be done towards reclaimed water and rainwater runoff into the independent...
With respect to characteristics of block trading rules, integrating various implementation mechanisms of demand side bidding (DSB), block bidding mechanism is extended to demand side and theory framework of block bidding mechanism incorporating demand side participation is proposed. Based on electricity pool pattern and with block bidding rules, electricity sellers and buyers can perform electricity...
The distribution and composition of the planktonic algae community in Xi Quanyan reservoir was investigated, it showed the dominant species were diatom and chlorophyta. According to the comprehensive trophic state of the multiple monitoring results of the different sampling points in the entrance, centre and exit of the Xi Quanyan reservoir, calculate the comprehensive trophic state index to gain...
With the rapid growth of semantic Web, more and more semantic Web data are generated and widely used. Efficient search and management of the semantic Web data is becoming a very important issue. In this paper, we present semantic Web data indexing scheme over a fully decentralized P2P network. Ontological knowledge is decomposed into atomic elements and then indexed with a distributed hash table (DHT)...
The paper gives the definition of consistency of interval number complementary judgement matrix, structuring object function, it gets the interval weight. Furthermore, it gets a simple method for checking the consistency of interval number complementary judgement matrix without having to solve linear program. Finally, a numerical example is given to illustrate the use of this method.
