The emergence of cloud finance has brought new opportunities for the financial management informatization construction of small and medium-sized enterprises. Compared with the traditional way of financial management informatization construction, cloud finance is more in line with the actual needs of small and medium-sized enterprises with complete internal organs due to the advantages of less investment, quicker results, on-demand self-service, improving the availability of business systems, and helping financial transformation. It can be said that cloud finance is a booster for the development of small and medium-sized enterprises, and will soon become the mainstream model of financial management informatization for small and medium-sized enterprises in the future. In order to help small and medium-sized enterprises to better develop cloud finance, the research group distributed questionnaires to small and medium-sized enterprises in the Guangdong-Hong Kong-Macao Greater Bay Area to investigate their satisfaction with the application of cloud finance, and to explore the practical application of cloud finance in small and medium-sized enterprises. This article uses spss to analyze the data collected to identify areas for improvement.

News as an important part of the open source intelligence has always played an important role in international relations and national security fields. However, the fine-grained sentiment analysis work such as Aspect-Based Sentiment Analysis (ABSA) tasks focused on the service industry and e-commerce comments and the Target Aspect-Based Sentiment Analysis (T-ABSA) tasks focused on the Twitter datasets, these two types of tasks usually limit the context to the fixed subjects or objects, simplifying the model by limiting several aspects simultaneously. In addition, the sentiment analysis work based on the news texts most focused on the chapters level. Therefore, based on the characteristics of news texts that it contains multiple subjects and objects, this paper proposed the Subject-Object Aspect-Based Sentiment Analysis (SO-ABSA) model, which can do fine-grained emotional element extraction in the context of indefinite subjects, objects and aspects. More emotional elements can be mined through SO-ABSA model. The proposed model can extract the uncertain entities efficiently and improve the accuracy of subjects and objects extraction. Moreover, the uncertain aspects also can be extracted flexibly and the sentiment analysis result can represent the subjects’ emotional tendency towards specific aspects. To evaluate our method, we built a subject-object oriented dataset (SOOD) with data sourced from 30,000 news articles. We propose a subject-object aspect emotion analysis model and evaluate the model on the SOOD dataset. The experimental results show the effectiveness of our model.

Occlusion is a key challenge in real-world on-road pedestrian detection task. Due to constrained viewpoint geometry, a pedestrian is very likely to be obstructed by other pedestrians and/or other objects such as cars and bicycles. For Advanced Driver Assistance System (ADAS), heavily occluded pedestrians are as important as reasonable pedestrians because they may burst out from crowds or roadside obstacles. In this paper, a human-cascaded network is proposed for robust detection of heavily occluded pedestrians. Specifically, a sharp-response proposal network (SRPN) is designed to refine the feature responses in a narrow area to handle crowded pedestrian detection, followed by outputting the head and full body proposals for diverse occlusion situations. After RoI-pooling, a visible-guided attention (VGA) module is developed to leverage the head and visible area information. The VGA module also suppresses the feature noise of occluded area to enhance the feature representation learning of the backbone network. Finally, a head-cascade RCNN (HRCNN) network is proposed to predict the pedestrian bounding box from the head proposal. The proposed approach is validated through a widely used pedestrian detection dataset: CityPersons. Experimental results show that our approach achieves promising detection performance (log-average miss rate, MR) improvement of 11.4% on heavy occlusion subset, compared to the baseline detector.

There are many hemiplegic patients with hand dysfunction caused by stroke. Restoring hand function can effectively improve the quality of life of patients. Traditional rehabilitation training can improve hand strength and flexibility, but there are few medical staff and high workload, which may easily lead to unstable training effect. Therefore, this letter designed a soft hand rehabilitation robot with multiple training modes. By analyzing the natural movements of human fingers, the flexible exoskeleton finger and driving unit are designed. The kinematics of the finger are derived to achieve uniform changes in the angle of the finger joints. The hand rehabilitation robot can support multiple training modes such as individual finger training, five-finger collaborative training, and left-right hand symmetry training. Experiments show that the hand rehabilitation robot can carry out continuous and stable finger joint training, and has a good rehabilitation training effect.

The flexible and easy-to-deploy Unmanned Aerial Vehicle(UAV) is used to control the manned-aircraft formations with highly dynamic topology changes, forming a manned and unmanned cooperative airborne network, which can effectively reduce network deployment costs while ensuring network connectivity. Aiming at the problem of UAV deployment, in order to optimize network reliability and deployment cost overhead indicators, a UAV deployment algorithm based on connectivity and cost minimization is proposed. Firstly, in order to achieve full coverage of the mission area to ensure connectivity, preliminary deployment is performed based on the communication range of the UAV. Then, based on deployment constraints and optimization indicators, the redundant UAVs in the preliminary deployment are determined and deleted. The experimental results show the effectiveness of the proposed algorithm.

Massive multiple-input multiple-output (MIMO) is one of the promising technologies that can offer large capacities in multi-user scenarios with a large-scale antenna system. However, the base stations (BSs) consume too much energy when all of the antennas are turned on. If the users’ traffic requirements can be predicted, we may turn on/off antennas as needed to save energy while at the same time, guaranteeing users’ satisfaction. In this paper, we propose a clustering-based wavelet-LSTM method to predict the users’ traffic requirement in the next interval. According to the prediction results, we determine the number of antennas that needs to be turned on in the next interval. Our method is tested against a real-world anonymous dataset from an operator in a city in China. In comparison with some algorithms in machine learning, numerical results show that our clustering based wavelet-LSTM method achieves higher prediction precision. Furthermore, changing the on/off states of antennas by our proposed prediction method, we could get about 15% gain in energy consumption compared with the energy efficient system where states of antennas are adjusted by the number of users within the BS coverage.

Internet carries a variety of emerging applications which exhibit diverse requirements on transmission. The traditional end-to-end transmission scheme that provides only location-based content delivery has become the bottleneck of deploying these emerging applications. In recent years, newly proposed network addressing schemes enable diverse transmission modes. But each of the schemes is advantageous only in its specific scenario. Integrating all these addressing schemes to optimize transmission efficiency for all applications is still an open problem.To this end, we present an intelligence serviced task-driven network architecture. It applies federated learning to identify the transmission characteristics of different tasks deployed. Then, it assigns appropriate addressing schemes and thus all the tasks of each application take advantages of the new addressing schemes. Our prototype implementation and experiments demonstrate that the architecture has significant improvements and is feasible to be deployed.

Traditional machining equipment typically does not provide online production information such as part production quantities, efficiency and abnormal operating conditions. In order to solve this problem, a real-time production information monitoring system for traditional machining equipment based on electric current signal has been development. Firstly, the data acquisition hardware system using current sensors is designed to collect the electric current signal of the equipment being monitored. Next, the current data is processed by calibration algorithm to obtain production process feature vectors. Finally, a feature matching algorithm is used to identify the operating status. Based on the above algorithms, a monitoring software system is realized by C++ programming language on Qt platform. The monitoring experiment was carried out with automobile transmission shaft parts. The experimental results show that the machining start time and end time of each machined part are correctly and timely identified, and the abnormal state of the equipment could be accurately identified. The developed system is suitable for real-time monitoring of the traditional machining equipment.

This paper deals with the problem of stochastic network calculus-based road side unit (RSU) location optimization at an intersection. Considering the stochasticity of data arrival rate at RSUs and RSU service capacity, the upper bound of vehicle-to-RSU (V2R) communication delay is derived using stochastic network calculus. Further, to hedge against the impact of the randomness of the traffic density on RSU location optimization, the problem is formulated as a two-stage nonlinear mixed-integer stochastic program. The objective function of this program is to minimize the investment cost of RSU location and the expectation of the penalty cost of the V2R communication delay upper bound. In the first stage of the program, the number and location of RSUs are optimized when the traffic density at the intersection is uncertain. In the second stage, when the traffic density is realized, the subareas of the intersection are assigned to the located RSUs to minimize the penalty cost. To find a global optimal solution to the problem, a Benders decomposition algorithm is proposed. The experiment results show that the proposed model is able to achieve 19.4 ms/per cost lower V2R communication delay, compared with the average-communication-delay-based model.
