In the current work, the nonlinear vibration of an embedded double-walled carbon nanotube (DWCNT) aroused by nonlinear van der Waals (vdW) interaction forces from both surrounding medium and adjacent tubes is studied. Using both Euler–Bernoulli and Timoshenko beam models, the relation between deflection amplitudes and resonant frequencies of the DWCNT is derived through harmonic balance method....

Deep learning models have recently been proven to be successful in various natural language processing tasks, including sentiment analysis. Conventionally, a deep model’s architecture includes feature extraction layer followed by fully connected used train the model parameters and classification task. In this paper, we employ with modified that combines Convolutional Neural Network (CNN) Bidire...

In this paper, a bi-lingual large vocaburary speech recognition experiment based on the idea of modeling pronunciation variations is described. The two languages under study are Mandarin Chinese and Taiwanese (Min-nan). These two languages are basically mutually unintelligible, and they have many words with the same Chinese characters and the same meanings, although they are pronounced differen...

The purpose of this study was to analysis the effect of management accounting information system (MAIS) based on decision support (DS) and business intelligence (BI) in return on investment (ROI) and return on equity (ROE) of Tehran stock exchange companies. We used analytical hierarchical process (AHP) through the weighting of MAIS based on DS and BI elements Then, questionnaires based on DS a...

The Information Technology and Internet techniques are rapidly developing. Interaction between enterprises and customers has dramatically changed. It becomes critical that enterprises are able to perform rapid diagnosis and quickly respond to market change. How to apply business intelligence (BI), manage, and diffuse discovered knowledge efficiently and effectively has attracted much attention ...
