As communication and high-speed internet make it easy to spread fake news on social media, scholars propose methods to detect it. However, existing approaches have limitations, such as reduced effectiveness without user information and high computational costs. Our proposed method, based on temporal and communication networks, is mainly used in the context of lack of user-related data and large textual datasets such as social media, forums, and online news. In sparse data settings, our proposed method can capture the propagation features of fake news for fake news detection, which is a feature extraction method based on building a propagation network for fake news detection. By studying the propagation pattern of fake news on social media, we obtain features belonging to the propagation network and test the source tweets using various machine learning classifiers. We also conduct experiments on realistic datasets to validate the method’s feasibility in social network scenarios.

In this paper, we apply deep learning-based (DL) approach to solve the hybrid precoding and combining design problem in millimeter wave (mmWave) multiple-input multiple-output (MIMO) systems. After training process, we feed testing data set into neural network (NN) and obtain phases of RF analog precoders and combiners. Given a RF analog precoder, we can acquire baseband precoders by using least square solution and the similar way is applied to RF analog combiner to acquire baseband combiner. As indicated in the simulation results for the evaluated spectral efficiency based on the outputs of DNN, it shows that the performance of our method is competitive.

Its functions include: (1) In addition to developing electric rearview mirrors for electric vehicles, it is equipped with memory motors, which can memorize at least 3 sets of positions. To provide the electric rearview mirror memory angle for electric vehicle driving, you can choose outside the rearview mirror angle and can memorize up to 3 sets of angles, which guarantees the initial safe driving angle of electric vehicle driving.

We introduce deep reinforcement learning (DRL) into a Taiwanese mahjong program, and compare the pros and cons of traditional tree search methods and DRL in terms of effectiveness and efficiency. Our DRL-based program aims to learn good strategies comparable to the state-of-the-art Taiwanese mahjong program Verylongcat, and has demonstrated effective learning capability in the experiments. Moreover, the required computation time of our DRL-based program is significantly lower than the Verylongcat version, bringing great advantage in time-limited tournaments.

Then, the proposed system sends the URLs to VirusTotal, a third-party security website for evaluation. Finally, the security score of each URL is presented to the smartphone user, providing them the choice to decide whether to remove an app with security concerns.

This paper uses TCAD to simulate the modulation of a 0.18-μm 60 V nLDMOS device with a floating P+ embedded in the drain side by dividing the drain side into one-half and embedding the floating P+ near the drain outer side, which will increase the P+-zone length in different modes.The simulation is carried out with an input current of 1E-5 amps, and the trigger voltage, breakdown voltage, and electric field of the devices can be obtained from the TCAD simulation. By embedding the floating P+, it was found that the electric field could be reduced and the breakdown voltage of the device could be increased. In the design, the floating P+ with a length of 9 μm is embedded in the drain outer side, and the breakdown voltage is increased from 96.42 V to 119.29 V, so that the ESD immunity of the device can be improved.

The factors of indoor air quality are affected by the density of people, the size and time of opening the door, and the arrangement of the air inlet and outlet of the ventilation equipment. We found that the optimal CO2 of the cross opening was reduced by 109.7 ppm/min through CO2 concentration detection. However, natural ventilation can result in higher indoor temperatures. Therefore, this study increases mechanical ventilation equipment and explores natural and mechanical ventilation to achieve ventilation energy saving.

Point cloud registration involves the task of finding the alignment between pairs of point clouds. Recently, deep learning-based approaches have been shown to achieve more accurate results due to the enhanced feature extraction and correspondence matching mechanisms. Most of the deep learning-based approaches estimate the registration parameters directly without explicitly estimating correspondences. Instead, the correspondences are learned implicitly while networks are trained, and the loss functions used are mostly related to errors of registration parameters. RPMNet, one of the state-of-the-art registration methods, includes an additional component in the loss function to maximize the sum of inlier probabilities in order to prevent the problem of labeling most points as outliers. In this paper, we propose to improve the RPMNet through the modification of the loss function by replacing the sum of inlier probabilities with the sum of maximal matching probabilities, with the purpose of increasing the probability of correct correspondence and thus enhancing the registration performance. Simulation results demonstrate that an order of magnitude improvement can be achieved by the proposed method.

Concealed pipes are widely used to transport water, air, natural gas, and sewage in buildings. In this paper, we propose an algorithm for designing concealed pipes in buildings such that the productivity of construction industry is enhanced. When routing concealed pipes in a building, the walls, floors, and ceilings form the workspace of the piping computation. We treat these slabs as vertices and generate edges between them, based on their connectivity. Consequently, the frame of the building is encoded in a graph, which constitutes the top-level representation of the workspace. Then all the slabs are divided into voxels by using regular grids, and the bottom-level representation of the workspace is created. The pathfinding of a pipe is carried out in two stages. First, the routing process generates a shortest path in the top-level graph to identify the slabs penetrated by the pipe. Then, the routing process creates the detail pipe path by using the voxels of these slabs in the bottom-level representation. Once this pipe has been constructed, the voxels occupied by it are deleted from the workspace and the routing computation is repeated to arrange other pipes.
