With the rapid development and popularization of mobile positioning devices such as mobile phones, location-based services play an increasingly important role in people’s production and life, which makes high-performance large-scale distance matrix calculation a key part of the optimization of many business scenarios. The distance matrix is used to calculate the shortest road distance of a group of starting and ending points in batches. Based on the Contraction Hierarchies algorithm, this paper proposes a method to quickly calculate the distance matrix between source nodes s and target nodes t, where the source nodes s $in$ S and target nodes t $in$ T. Under the scale of the road network in mainland China, take $|mathrm{S}|=|mathbf{T}|=10000$, the average solution time of the algorithm is only 7.2 minutes, which can meet the needs of various application scenarios.

Ontologies are crucial for data integration and information sharing. However, due to the different knowledge backgrounds of domain and ontology developers, the heterogeneity problem of multi-source ontology existence is more prominent, and ontology mapping is an important way to solve the ontology heterogeneity problem. However, the ontology similarity calculation methods among them still need to be improved in terms of accuracy or stability. In this paper, we propose an ontology similarity calculation method based on graph attention networks, which models ontologies as heterogeneous graph networks and uses the graph attention network model to introduce an attention mechanism to dynamically consider the influence of edge weights to achieve neighbor aggregation and perform similarity calculation. The experimental results show that this method has higher accuracy than the existing ontology similarity calculation methods.

Feature Pyramid Network (FPN) is a basic but important component in target detection system. Together with target detection algorithms, such as SSD, Faster R-CNN and YOLO series, they have achieved good detection results for large targets with high resolutions, but the performance is less effective when it comes to detect small targets that contain relatively little semantic information. And small target detection is quite common in daily life, such as face recognition at long distances, traffic sign detection in automatic driving, etc. That means it is significant to break the bottleneck of target detection and get better accuracy performance. In this article, based on the FPN, we propose an improved network structure (IMFPN) from two aspects to get a better accuracy result in small target detection task. In the first aspect, we improve the feature map pyramid structure for feature enhancement, reduce the problem of information loss during feature map fusion and get the semantic information of multiscale feature maps. In the second aspect, we concentrate on the problem of information loss in the pooling process of feature maps, we propose an improved version of the PRRoI pooling method that combines RoI Pooling and RoI Align Pooling. And we also optimize the positioning of the frame through a new IoU calculation standard. Based on these above ideas and methods, we propose a small target detection method based on feature enhancement and positioning optimization.

Software clock data recovery (CDR) is a critical component of a high-speed serial link that recovers the reference clock from a serial signal, which are generally used in real-time sampling oscilloscopes and electronic design automation software. The common method for calculating the period of the reference clock is to extract the rising and falling edges of the signal, and then calculate the difference between adjacent transition edges, so that a pulse width sequence is obtained. By performing statistics on this sequence, it can be found that the value of the position of the first peak of the statistical histogram is the period of the reference clock, the position of the second peak is twice the period of the clock, etc. The period of the clock can be calculated by weighted average. However, high-speed serial signals inevitably have duty-cycle-distortion (DCD) jitter, and DCD seriously affect the determination of the position of the peak of the above statistical histogram, there are many spurious peaks near the actual peak. This article proposes an improved method of calculating the clock period, which can eliminate the influence of DCD and to obtain an accurate clock period.

As smart cities continue to be developed, network traffic surges. Although edge computing improves the quality of service by shifting computing tasks from cloud computing centers to locations closer to the edge through a multi-layer distributed computing model, there are security risks in the face of central node failures and internal malicious attacks, which make it difficult to provide stable and reliable services. In this paper, we design a trusted management model of edge device in smart city with blockchain, introducing blockchain technology into the research of smart city construction. It uses the blockchain distributed architecture and decentralization idea to realize the trusted collection and storage of sensory data. And based on this architecture, a new reputation-based PoW consensus algorithm is proposed to provide a trust mechanism for IoT devices. The algorithm greatly increases the cost of malicious attacks launched by the IoT device, effectively prevents malicious attacks on devices, and achieves trusted management of edge device behavior. The smart city application based on the proposed method verifies its feasibility, effectively prevents malicious attacks from nodes, and enhances the information security of the system.

With the increase of the related facilities and services around the driver, the driver’s identity becomes more and more important, so the research on the driver’s identification is also increasing gradually. Since the emergence of the online car-hailing platform represented by Uber, people’s travel has become more and more convenient, but there have also been many problems surrounding the identity of the driver. For example, the actual information of the driver does not match the information registered on the platform, which increase safety risk for passengers. In this paper, we propose a novel driver identification scheme that first converts the raw data of the x and y axes of the accelerometer into feature vectors by a novel data transformation method which adds frequency domain perspective on the basis of time domain perspective, adopts sliding window and fast Fourier transform and then uses these feature vectors as the input of neural network. Finally, we identify the driver through our designed driver identification algorithm, which accepts as input the probability distribution of the network output. In our experiments, we experiment with 10 drivers and use accuracy, precision, and recall as outcome metrics. Experimental results show that the performance based on time and frequency features is better than that of time or frequency features alone.

In mobile edge computing (MEC) network, computing offloading can alleviate resource constraints and improve service quality effectively. Meanwhile data transmission in Device-to-Device (D2D) communication can realize resource sharing and balance among different users, in order to improve system spectrum utilization and reduce communication delay. Aiming at minimizing the task delay and terminal energy consumption in MEC network, a joint optimization problem considering task offloading and computing resource allocation is formulated in D2D-assisted MEC network by building cost optimization model with multi-objective constraints. Moreover, the original problem is decoupled as two sub-problems which are solved by discrete ternary particle swarm optimization (DTPSO) algorithm and Lagrange multiplier method, respectively. Simulation results show that compared with three other typical methods, the proposed scheme in this work can effectively reduce task execution delay and terminal energy consumption.

In the Marine Predators Algorithm (MPA), a set of solutions is randomly generated in a given search space and the optimal solution is searched through an iterative process, although MPA has shown good performance, it has not solved the problem of local optimal solutions and premature convergence caused by insufficient iterations of the search agent, and its optimization performance still has a lot of room for exploration. Therefore, this paper proposes a trigonometric function-based MPA (TF-MPA) algorithm. First, the trigonometric function is used to optimize the position update of the prey matrix; then the cosine function is used to define the inertia weight coefficient; finally, the sine function is used to define the nonlinear step size control parameters. The effectiveness of TF-MPA is tested on nine standard test functions, and the results show that the TF-MPA algorithm has faster convergence speed and higher stability than the traditional MPA algorithm and other improved algorithms. This proves the effectiveness of the algorithm.

The banana diseases directly affected banana quality and yield, so a detection method for banana leaf diseases based on image processing is proposed. Firstly, the color segmentation method is used to remove the green background such as healthy leaves, and weed from original banana leaf disease image collected by smart phone. And the segmented image is converted to V component gray image of YUV color space and then the Ostu segmentation which uses the minium intra-cluster or the maximum inter-cluster gray variance to segment the image, and the area threshold method are used to remove the non green background such as soil, and dead grass, thus extracting a complete disease regions. Next, these color features such as the color means, color variances, and color skewnesses of R, G, B, Y, U and V component in the disease regions, are extracted and secleted to construct a set of feature vector of each banana leaf disease with standard image samples. Finally, the minimum euclidean distance classifier is used for banana leaf disease recognition. The results show that the method can effectively segment the disease regions from the original banana leaf disease image and has high recognition rate with 91.7% for gray leaf spot disease and 90% for sigatoka leaf spot disease. Therefore, it is proven that this method has high accuracy and reliability in banana leaf disease recognition, having better promotion and application value.
