Due to the lack of labeled data in many real-world scenarios, Graph Neural Network models that require a large volume of labeled data are not effective, and research based on unsupervised learning frameworks has become essential. To solve the problem of sparsity in labeled graph data, this paper proposes an unsupervised graph representation learning method based on graph infomax and dynamic graph attention mechanism(IMDGA). this method conducts unsupervised learning based on the idea of contrastive learning and optimizes the encoder by calculating the maximum mutual information between the graph's local information and global information. At the same time, we use a dynamic Graph Attention Network as an encoder model to prevent the Graph Convolutional Neural network's inability to adapt to neighbor nodes with different weights. Finally, link prediction experiments on three public data sets of cora, citeseer, and pumbed show that the proposed model has achieved superior results compared with other graph representation learning, showing its effectiveness and competitiveness.

Although the general event extraction model has achieved good results in the standard data sets, there is a gap in the extraction results in low-resource environments. the general event extraction model still has room for improvement in the performance of special fields. therefore, this paper proposes a semi-supervised reading comprehension event extraction model adapted to transfer learning, based on improved UDA for data enhancement, called SSDAEE, which can increase the accuracy of reading comprehension event type recognition. SSDAEE has a good performance on the public opinion data set. It can not only enhance a small number of supervised data in low-resource fields with unsupervised data but also improve the generalization ability of the model. Experiments show that when only 5% unsupervised data is used, the F1 score of SSDAEE on the public opinion data set is increased by 9% compared withthe fully supervised model, and by 2% compared with other semi-supervised models.

Cloud computing is one of the most used distributed systems for data processing and data storage. Due to the continuous increase in the size of the data processed by cloud computing, scheduling multiple tasks to maintain efficiency while reducing idle becomes more and more challenging. Efficient cloud-based scheduling is also highly sought by modern transportation systems to improve their security. In this paper, we propose a hybrid algorithm that leverages genetic algorithms and neural networks to improve scheduling. Our method classifies tasks withthe Neural Network Task Classification (N2TC) and sends the selected tasks to the Genetic Algorithm Task Assignment (GATA) to allocate resources. It is fairness aware to prevent starvation and considers the execution time, response time, cost, and system efficiency. Evaluations show that our approach outperforms the state-of-the-art method by 3.2 % at execution time, 13.3 % in costs, and 12.1 % at response time.

Large-scale access to distributed photovoltaics leads to power imbalance and frequent voltage fluctuations in distribution station areas, increasing the difficulty of operation control of distribution networks. To solve these challenges while improving the utilization rate of distributed photovoltaics, this study proposes a method for calculating the maximum hosting capacity (HC) of distributed photovoltaics in distribution networks, considering the flexible interconnection of low-voltage distribution station areas. First, two types of networking modes of the flexible interconnection of distribution station areas are analyzed and mathematical models are developed for them. then, an optimization model of the maximum HC of distributed photovoltaics in a distribution network that considers the flexible interconnection of distribution station areas is established, and the increasingly tight linear-cut algorithm is used to solve it, which aims to narrow the gap introduced by the convex relaxation to get the optimal solution. Finally, the accuracy of the model and algorithm is checked in the modified IEEE 33-node distribution network.

Building Energy Management systems (BEMS) are becoming very popular, for providing net Zero Energy Buildings (nZEBs). Attachment of these systems through IoT technologies, enables the building owners as well as utility companies to control energy's usage, generation, and storage in a more smart and real time manner, which is the foundational concept for Internet of Energy (IoE). High number of buildings especially in metropolitan areas imposes high amount of computation resources and increased communication and computation delays to the central cloud servers. In this paper, we first describe the details of a real IoT-based large scale deployment of office buildings energy management system in Greater Tehran Electricity Distribution Company (GTEDC), and then we propose an edge computing solution to reduce the complexity and delay of data dissemination in the system expansion phase.

Driven by the limitation of legacy network communications, recent years have seen a paradigm shift in network architecture, from the conventional TCP/IP towards Software Defined networking (SDN). the main feature of SDN is to give more flexibility to the network by pushing control from forwarding devices into scalable centralized orchestration. this paradigm enables using forwarding storage and processing capacity for caching content at the network level. the objective of this study is to address the Quality of Experience (QoE) problems in video applications. To this end, we propose a network-assisted QoE-aware bitrate adaptation algorithm that works in cooperation with MPEG-DASH’s proposed SAND technology and virtualized in-network caching function (denotes vDANE). In the proposed framework, client quality adaptation can be assisted by vDANE according to network bandwidth and availability of the appropriate segment/bitrate stored in vDANEs hosted by OpenFlow switches. Simulation results indicate that the proposed method can improve QoE parameters compared with other solutions.
