The smart grid is now being deployed in many countries to provide cleaner and greener energy to the consumers. To implement this efficiently and effectively appropriate data collecting, processing and transmitting infrastructures are needed to be in place. Smart meters are used to measure the energy consumption details and patterns and transmit to meter data management system (MDMS) with the help of data aggregation units (DAU). The sheer amount of data need to be collected from the consumers are very huge and they fall under the category of big data. Currently, all the data collected from smart meters are stored in a centralized place for processing to forecast the energy demand. This approach is becoming a bottleneck for efficient data collection due to limited bandwidth capacities of Power Line Communication (PLC). In this paper, we propose a framework for distributed data aggregation approach with the help of fog computing architecture. With this approach the amount of data sent to the centralized storage space is limited and, therefore, the capacity of PLC is virtually improved without compromising the functionality.

The new emerging applications in 5G network, in the context of the Internet of Everything (IoE), will introduce high mobility, high scalability, real-time, and low latency requirements that raise new challenges on the services being provided to the users. Fortunately, Fog computing andcloudcomputing, with their service orchestration mechanisms offer virtually unlimited dynamic resources for computation, storage and service provision, that will effectively cope with the requirements of the forthcoming services. 5G will use the benefits of centralized high performance computingcloud centers, cloud and fog RANs and distributed peer-to-peer mobile cloud that will create opportunities for companies to deploy many new real-time services that cannot be delivered over current mobile and wireless networks. This paper evaluates a model for fog andcloud hybrid environment service orchestration mechanisms for 5G network in terms of energy efficiency per user for different payloads.

Taking the irrationality of staff scheduling in China Geography Census(CGC) into consideration, this paper establishes a personnel optimization scheduling model. It is based on some assumptions according to characteristics in CGC's (or National Geographic Conditions Monitoring) production process. As optimal dispatch of personnel involves in large-scale, high dimension and nonlinear problems, the standard genetic algorithm (SGA) has drawbacks of premature and slow convergence, as well as poor local optimization ability. So this paper adopts cloud adaptive parallel simulated annealing genetic algorithm (PCASAGA), which integrates adaptiveness, cloud reasoning with simulated annealing mechanism to improve SGA's performance. And also parallelcomputing function is introduced. To Take Shandong Remote Sensing Technology Application Center as an example, it shows that PCASAGA is superior to SGA in convergence speed and optimization ability. It also proofs that homogeneous and heterogeneous situations have not only distinction but also connection as influence factors increase, such as number of return to modify (n), quality sampling rate (s) and error rate (e). The distinction is changes of structure's proportion, the former case shows flat or falling trends, and the latter one has no unified state. On another side, the connection is the increased optimal completion time. The findings have guiding significance for staff optimization in National Geographic Conditions Monitoring in aspects of engineering plan, cost calculation and so on.

A geomechanical model and a multiphase black oil model are iteratively coupled in this paper. parallelcomputing is employed to handle large scale problems by benefiting from its features of distributed memory storage and efficient runtime reduction. The finite element method and the finite differencemethod are employed to discretize the two models, respectively. The geomechanical model is developed with the capability of simulating the rock matrix deformation with complex constitutive laws and its effects on reservoir properties. The multiphase flow model is modified by introducing geomechanical variables in a conventional flow model. A coupling strategy is carefully proposed to enable tight and dynamic interactions between these two models, as well as improving parallel computational efficiency. Example problems are presented to demonstrate the utility and efficiency of the coupled models. Expected geomechanical phenomena are illustrated by numerical experiments and validated by commercial software. In addition, for testing the scalability behaviour, field scale problems with millions reservoir and geomechanical grid blocks are performed. The results show encouraging speedups which indicate the integrated models can be an efficient and useful tool for evaluating and analyzing oil and gas production of stress-sensitive reservoirs.

In current industrial practice, thousands of industrial alarms generating millions of alarm events, are built into digital control systems typically found in power generation facilities, power grid and communication networks, oil refineries, petrochemical plants, and other manufacturing plants. Given the increasing complexity of such systems, an effective approach to managing alarms and the stream of data they generate becomes imperative. Hitherto, much of alarm management techniques are mostly rule-based with intensive engineering domain expertise requiring an understanding of the underlying physical processes and special skills on the part of the plant operator. This paper describes a novel graph-based data mining approach that can be used to analyze industrial alarm data. Our method leverages the availability of large timestamped historical alarm events datasets. Using these historical datasets, we developed a graph analytics model that identifies redundant alarms and the series of alarms associated with or leading to critical events. Our experiments using real-world (a power generation station and an oil refinery) industrial alarm datasets demonstrate that our proposed method is both scalable and efficient.
