This paper adopts two mathematical approaches, data envelopment analysis (DEA) and grey relation analysis (GRA) to measure DEA efficiency using the sample of 69 listed US internet companies. A total of 40 indicators were initially selected for the efficiency evaluation, with 21 related to DEA-input indicators and 19 to DEAoutput indicators. Eight representative indicators selected using GRA are...

Weight gain and diabetes have been reported during treatment with atypical antipsychotic drugs (AAPDs). Patients treated with the glucocorticoid receptor antagonist (GRA) and the progesterone receptor antagonist (PRA) mifepristone [estra-4,9-dien-3-one, 11-[4-(dimethylamino)phenyl]-17-hydroxy-17-(1-propynyl)-(11β,17β)-(9CI)] experienced significant reduction in the weight gain observed when pat...

In recent years, cultural and creative industry park is becoming a kind of hot to promote industrial restructuring improve the quality urban space. For this reason, parks are planning build across country. Currently, that develop better than others thank government’s overall planning, construction, marketing, management. At same time, new face enormous challenges, such as how have together indu...

BACKGROUND During pregnancy, toxoplasmosis and rubella can cause serious damage to the mother and the foetus through vertical transmission. Early diagnosis enables implementation of health measures aimed at preventing vertical transmission and minimising damage caused by these diseases. OBJECTIVE Here, we report the development of a multiplex assay for simultaneous detection of IgG antibodies...

The college tennis classroom teaching effect evaluation is viewed as the multiattribute group decision making (MAGDM). probabilistic double hierarchy linguistic term set (PDHLTS) not only conforms to people’s language expression habit of “adverb + adjective” but also can accurately depict its importance in real MAGDM. Therefore, this paper comes up with grey relational analysis (PDHL-GRA) metho...

Software Estimations provide an inclusive set of directives for software project developers, project managers, and the management in order to produce more realistic estimates based on deficient, uncertain, and noisy data. A range of estimation models are being explored in the industry, as well as in academia, for research purposes but choosing the best model is quite intricate. Estimation by An...

In this study, we propose an optimized network information security evaluation GRA-BPNN model based on gray correlation analysis method combined with BP neural model, and make corresponding optimization for index. Simulation experiments are conducted to analyze the experimental simulation results show that test sample values reach best training performance at 7th iteration after 13 iterations, ...

Abstract Surface roughness and heat-affected zone (HAZ) are the important features which influence performance of laser-drilled products. Understanding laser process parameters on these responses identifying cutting conditions for simultaneous optimization a primary requirement in order to improve drilling performance. Nevertheless, no such contribution has been made literature during AISI 303 ...
