Urban rail transit (URT) plays crucial economic, social, and environmental roles may generate positive externalities that can influence the residential property values (RPVs) in real estate markets. Little attention has been given to exploring impacts with respect both spatial temporal perspectives. This paper explores of URT on RPVs 480 gated communities dimensions using hedonic price model a panel data set from Zhengzhou for 2012–2016. The results show following: (1) does have significant...

An improved SegNet semantic segmentation model is proposed to address the issue of traditional classification algorithms and shallow learning not being suitable for extracting information from high-resolution remote sensing images. During research process, space images obtained GF-1 satellite were used as data source. In order improve operational efficiency encoding network, pooling layer in network removed ordinary convolutional replaced with a depth-wise separable convolution. By decoding...

We propose a transceiver design method based on an autoencoder (AE) network for multi-color visible light communication (VLC) systems. Taking into account the chromaticity constraint described by MacAdam ellipses and peak-value of transmitted signals, proposed AE utilizes layer integrated loss function which different from previous designs. The new structure can be suitable VLC systems with numbers colors. Additionally, noisy channel state information (CSI) is employed during training in...

This study proposes that firms witnessed competitors' winning corporate social responsibility (CSR) awards will experience an upward comparison, which can motivate them to undertake intensive CSR activities in the post-award period. The influence of witnessing on focal firms' intensity is stronger when have high similarity with award- firms. Our findings also show conducted by after post- award period give rise higher performance compared same pre-award Using a sample competitors, we find...

A deep deterministic policy gradient (DDPG)-based energy management strategy (EMS) is proposed for fuel cell hybrid vehicles (FCHVs) in this research, which a reinforcement learning (DRL) algorithm and achieves the continuous control field contrast to general Q (DQL)-based EMSs. Specifically, system efficiency characteristic used as prior knowledge improve effect. In addition, prioritized experience replay (PER) other techniques are adopted computational of DDPG. The results demonstrate that...

Due to the widespread adoption of social networks, image-text comments have become a prevalent mode emotional expression compared traditional text descriptions. However, there are currently two major challenges. The first is question how extract rich representations effectively from both and images, second cross-modal shared emotion features. This study proposes multimodal sentiment analysis method based on deep feature interaction network (DFINet). It leverages word-to-word graphs attention...
