Grid computing technologies have played an important role in both scientific and commercial communities in recent years. Initially, grid applications were concerned principally on the storage, replication and movement of file-based data, but now they are increasingly being used in many relative areas of e-science and e-business. The need for data access and integration becomes widely aware. In this paper, the Muse project presents a feasible approach, which is based on the design and implementation of OGSA-DAI architecture, to facilitate scientific researchers using grid services in their collaborative work. The Muse, with an aim of providing integrated access to complex, heterogeneous and distributed data resources, mainly intends to build a high-level middleware to extend the functionalities of OGSA-DAI framework. This paper focuses primarily on access and integration of relational databases, and shows how Muse supports a demonstrated application scenario in detail.

In this work, we consider the usage of wireless sensor networks (WSN) to monitor an area of interest, in order to diagnose on real time its state. Each sensor node forwards information about relevant features towards the sink where the data is processed. Nevertheless, energy conservation is a key issue in the design of such networks and once a sensor exhausts its resources, it will be dropped from the network. This will lead to broken links and data loss. It is therefore important to keep the network running for as long as possible by preserving the energy held by the nodes. Indeed, saving the quality of service (QoS) of a wireless sensor network for a long period is very important in order to ensure accurate data. Then, the area diagnosing will be more accurate. From another side, packet transmission is the phase that consumes the highest amount of energy comparing to other activities in the network. Therefore, we can see that the network topology has an important impact on energy efficiency, and thus on data and diagnosis accuracies. In this paper, we study and compare four network topologies: distributed, hierarchical, centralized, and decentralized topology and show their impact on the resulting estimation of diagnostics. We have used six diagnostic algorithms, to evaluate both prognostic and health management with the variation of type of topology in WSN. © 2016 IEEE.

Dedicated Cluster Parallel Computers (DCPCs) are emerging as low-cost high performance environments for many important applications in science and engineering. A significant class of applications that perform well on a DCPC are coarse-grain applications that involve large amounts of file I/O. Current research in parallel file systems for distributed systems is providing a mechanism for adapting these applications to the DCPC environment. We present the Parallel Virtual File System (PVFS), a system that provides disk striping across multiple nodes in a distributed parallel computer and file partitioning among tasks in a parallel program. PVFS is unique among similar systems in that it uses a streams-based approach that represents each file access with a single set of request parameters and decouples the number of network messages from details of the files striping and partitioning. PVFS also provides support for efficient collective file accesses and allows overlapping file partitions. We present results of early performance experiments that show PVFS achieves excellent speedups in accessing moderately sized file segments.

Most biological functions are presented through protein-protein interaction (PPI) networks. PPI networks show the complex protein-protein interaction relationship within the organism. The generation or destruction of these interaction may lead to changes in biological functions. The latest research results show that the interaction network of species with a higher degree of evolution has higher resilience. Here we explore the resilience changes of a single species during its evolution. We obtain data from public and published websites SNAP. We have proved that no matter what the network structure is, whether it is large or small, when the network fault gradually increases, the resilience gradually decreases. This also indicates that the network with the greatest resilience has a higher degree of evolution. © 2022 IEEE.

With the development of the mobile Internet, supporting multi-user has become a popular concern for Internet-based algorithms. In this paper, an efficient watermark embedding framework is proposed to achieve secure outsourced image watermarking in multi-user settings. In addition, an authentication mechanism for authorized users is designed to ensure the security and correctness of the information. The proposed method enables watermarking operations in complex outsourced environments while embedding watermarks in encrypted images of multiple users. The experimental results show that the framework is feasible and scalable. © 2022 IEEE.

As one of the portals of the Internet, web application brings convenience to human society, but also has many problems, such as phishing attacks, malware downloads, privacy breaches, etc. In order to more accurately identify malicious web pages, reduce the risk of network attacks, this paper designs a multi-level detection model according to the different level characteristics of web pages. The model uses LDA-SECNN to learn the characteristics of web page content, uses random forest algorithm to learn the static characteristics of web page, and finally combines the two outputs to determine. Experiments show that the multi-level model can improve the accuracy of the model, and has good stability and convergence. © 2021 IEEE.

If the country wants to rejuvenate, the countryside must be rejuvenated. Achieving rural revitalization requires an effective engine and continuous power. There is huge room for digital empowerment in the modernization of China's agriculture and rural areas, and the digital economy will become an effective engine and continuous driving force for rural revitalization. This paper sorts out the internal mechanism of the digital economy to promote rural revitalization, and on this basis puts forward the development path of driving rural revitalization with the digital economy, including: reshaping the rural digital ecology with new digital infrastructure, and activating rural human resources elements by improving new digital skills, to promote the transformation of rural industries by building a county-level industrial Internet, and empower rural characteristic industries with digital new technologies. © 2022 IEEE.

Matching user requirements in parallel programming

FUTURE GENERATION COMPUTER SYSTEMS-THE international JOURNAL OF GRID computing AND Escience 1996年第4期12卷 291-305页

While productive use of parallel systems for business applications is quickly growing, their usage for scientific applications is far below expectations. The main reason is that programming of parallel systems is still far too complex. Starting from an analysis of the user requirements, this paper explains our strategy towards next-generation parallel programming environments. We first discuss the problem areas of parallel programming from a user's point of view and give an overview on existing low-, high- and intermediate-level tools. We summarize our objectives and the status of our research. Then we discuss three enabling technologies to overcome current-days limitations of tool environments for parallel computing: formal specification languages, artificial intelligence, and compiler technology. The impact of these technologies on the components proposed for a next-generation programming environment is discussed in detail.

Wildfire, especially uncontrolled flammable vegetation hazard in rural or wilderness areas, seriously affected human life and safety, prediction methods has been researched widely in recent decades. According to Amazon forest fire situation, an advanced system hierarchical clustering model is established in this paper, and the diffusion simulations of Amazon forest fire is implemented by using the cellular automata model, which constructed with the previous model. Then, the diffusion speed and diffusion range of different brightness parameters are analyzed. Furthermore, combined with the three-dimensional effect of fire and smoke simulated by particle system, the entropy weight TOPSIS model is constructed to the optimized ranking of wildfire risk index with its longitude and latitude, and obtain the relationship diagram of latitude, longitude and wildfire risk index after extracting data. The feasibility and rationality of the proposed method is verified by simulation results. © 2021 IEEE.
