Information Retrieval (IR) technology was widely used in traceability between design documents and source codes. However, the vocabulary mismatch between the design documents and the source codes affects the performance of IR. Aiming at the above situation, a dynamic tracing method from design documents to source codes combining IR technology and SQL statement is proposed in management information system. Firstly, the similarity of the two is calculated by IR and the candidate links are generated;Then, the SQL statement required by the codes is automatically estimated according to the design documents, and the SQL statement is compared with the actual SQL statement in the codes to correct the design documents-codes similarity score;Finally, set a threshold to determine the trace links of the design documents to the source codes. The experimental results show that this method can improve the similarity score of code classes with relevant SQL statements in the design documents, so as to improve the ranking of code classes in the candidate links, extract the trace links that may be missing in IR method under the action of threshold, and finally improve the precision of trace results. © 2021 IEEE.

In order to meet the needs of intellectual property protection and controlled sharing of scientific research sensitive data, a mechanism is proposed for security protection throughout 'transfer, store and use' process of sensitive data which based on blockchain. This blockchain bottom layer security is reinforced. First, the encryption algorithm used is replaced by the national secret algorithm and the smart contract is encapsulated as API at the gateway level. Signature validation is performed when the API is used to prevent illegal access. Then the whole process of data up-chain, storage and down-chain is encrypted, and a mechanism of data structure query and data query condition construction based on blockchain smart is provided to ensure that the data is 'usable and invisible'. Finally, data access control is ensured through role-based and hierarchical protection, and the blockchain base developed has good extensibility, which can meet the requirement of sensitive data security protection in scientific research filed and has broad application prospects. © 2022 IEEE.

In the railway station scheduling system under the water-rail combined transport mode, how to reasonably allocate equipment resources according to the operation tasks, improve the efficiency of mechanical loading and unloading, and reduce the cost of loading and unloading operations, has become an urgent problem in the process of building a modern port. In this paper, a railway station scheduling algorithm based on multi-objective particle swarm optimization algorithm (RSSAMOPSO) was designed. The multi-objective particle swarm algorithm was used to solve the multi-objective optimization problem of railway station scheduling. Aiming at the problems of decreasing con-vergence speed and the lost of the diversity of the solutions, a compression factor and an adaptive mutation operator are introduced. The improved multi-objective particle swarm algorithm (IM-MOPSO) is combined with the compression factor and adaptive mutation operator to obtain the optimal operation sequence and various equipment task allocation schemes. Experimental results show that the above method has a large practical significance and practical value for improving the efficiency of mechanical loading and unloading in the railway yard and reducing the operating cost of the railway yard. © 2021 IEEE.

Feature matching is a critical step in a variety of vision-based applications. However, it is difficult to customize a general method due to complicated image transformations. In this paper, we formulate feature matching into a mathematical problem, which is simple and does not rely on any specific model. Specifically, we construct an objective function based on two constraints (i.e., geometric constraint and consistency constraint). Different from the previous work, we exploit the interaction of these two constraints to reject outliers. Besides, we adopt an iterative strategy to boost the number of inliers. To accelerate the matching process, we use the parallel computing to obtain the information of K nearest neighbors for each feature point. Experimental results on ten image pairs (undergo different image transformations) compared with other state-of-the-arts demonstrate our superiority both in accuracy and efficiency.

Considered a combination of Software-as-a-Service and business Process Outsourcing, business Process as a Service has the potential to provide the killer applications able to propel Cloud computing to a higher technological level. Following a general overview of the current state-of-the-art in research and implementation of the BPaaS, we propose a mind switch towards the applicability of re-usable business process patterns and a multi-modeling approach for BPaaS design, deployment and operation. In order to demonstrate the feasibility of the approach we provide two examples of BPaaSs that can take advantage of Cloud computing in order to gain clear benefits in terms of services' efficiency. © 2012 IEEE.

Workplace stress is a significant issue that needs attention in e-commerce. This article analysed how stress is caused in e-commerce workers (employees and entrepreneurs). Findings show that sources of workplace stress include task nature, behaviour & managerial issues, communication, identity & life, and the grand society factor. Furthermore, the reasons workplace stress can be created in these pathways are tightly associated with higher expectations and requirements of the e-commerce workplace under the influence of external industrial development and more robust work challenges. Finally, this paper also introduces what could be done to relieve the concerning state of workplace stress for e-commerce workers. In general, all 3 relative parties - individuals, work groups, and society all need to make joint efforts and make a contribution by creating a beneficial industrial & occupational environment and take care of employees') mental states. © 2022 IEEE.

business process management is concerned with the design execution, improvement, and monitoring of business processes. Systems that support the enactment and execution of processes have extensively been used by companies to streamline and automate intra-organizational processes. However, today's business enterprises must deal with global competition, heterogeneity, and rapidly develop new services and products. To address these requirements, the services reuse-based approach allowed enterprises to reconsider and optimize the way they do business, and change their information systems and applications to support collaborative business processes. Service choreographies support the reuse-based service-oriented philosophy in that they represent a powerful and flexible approach to realize systems by (possibly) reusing services and composing them in a fully distributed way. Nevertheless, for inter-organizational processes, challenges of collaborative design and lack of mutual trust have hampered a broader uptake. In this paper, we show an early stage approach to address the problem of trust in services choreography by using Blockchain technologies, in order to support the decentralized and peer-to-peer collaboration in a trustworthy manner, even in a network without any mutual trust between nodes.

Using internet of things (IoT), we can connect and enable every object to send or receive data through the internet. When it comes to real life applications we can make use of this technology for easy communication through home automation. Smart homes, smart agriculture, smart automobiles, and smart electronic gadgets are the examples of IoT-based applications. When more number of objects is connected in distributed environment, controlling and managing the device is much difficult. Due to IoT enabled framework, the number of requests coming to the cloud computing environment is increasing exponentially. The scheduling algorithm which is used in such cases should be efficient to handle various requests coming from these connected devices. The objective of this paper is to develop efficient scheduling mechanism which controls home appliances remotely by using any android or smart phone. Since the devices are connected over cloud computing environment, the proposed method can efficiently schedule the tasks. Copyright © 2021 Inderscience Enterprises Ltd.

This article presents a new methodology using distributed algorithms to identify and prevent errors in production and service. A sequential production/service line is selected to challenge the analysis, and reveal if the distributed algorithms can outperform centralized algorithms in automating error prevention. Agent-based error prevention algorithms (AEPAs) are developed for distributed agents to identify and prevent errors with decision rules. Analytical studies and simulation experiments are conducted to compare AEPAs with traditional centralized error prediction and detection algorithms. The results show that the AEPAs employing nominal and optimistic rules perform better than the centralized algorithms in terms of preventability and reliability. Collaboration among agents improves AEPAs' performance. It is recommended to prevent errors by two agents simultaneously executing the AEPA employing the integrated nominal rule.

With the development of flash memory, its storage density has gradually increased, but its reliability has been greatly reduced. Now, flash memory relies on LDPC to solve this problem. Although LDPC (Low Density Parity Check Code) can correct data with a high error rate, it will cause a lot of delays. The refresh operation can cause the LDPC decoding delay. In the work of this article, we propose a precise refresh strategy. On the basis of high latency pages, according to the characteristics of data access frequency, we take the read-hot data in the write-cold data as our refresh target. We test the performance of the precise refresh scheme through different workloads. Compared with ordinary refresh schemes, the average response time of flash memory storage devices is reduced by 16%-49% and the lifetime of flash memory is extended. © 2021 IEEE.
