However, it is possible to re-calculate all the next blocks in a closed and permissioned network, such that all altered blocks will become valid again. In other words, only chaining blocks to each other, based on the hash of the previous one, cannot ensure the integrity and the security of the data and protect transactions against tampering. In this paper, we motivate why permissionless blockchain in an open network should be considered as the only acceptable type of blockchain and show that permissioned blockchain and closed network makes chaining transactions (i.e. blockchain) as an unhelpful structure. Of course, this never means that we ignore the existing problems in permissionless blockchains (such as, scalability of the network and transaction throughput), but also, we argue that permissioned blockchain cannot be an acceptable solution for those problems, where chaining transactions will no longer be meaningful. In other words, in a closed network, we no longer need to chain transactions. Although, this is a central issue and has been addressed in recent years, we are trying to bring new elements and an enriched point of view.","PeriodicalId":11452,"journal":{"name":"e Informatica Softw.

At very low signal-to-noise ratio (SNR), which is lower than -10dB, the DSFH fails to synchronize. Synchronization acquisition method via a combined multi-signal detection (SAMCMD) is proposed. The feature of a short sequence of frequency hopping (FH) frequency point is utilized to express the information of the time of date (TOD), and the time accumulation of several FH signals is used to extend the detection time. This method can not only be appropriate for DSFH but also greatly improve the synchronization performance at low SNR. Explain the principle and structure of the SAMCMD. And obtain the performance of this method of the SDR synchronization acquisition. The conclusions are as below: 1) the longer detection time is, the better the anti-jamming performance of SAMCMD is; 2) SAMCMD can gain about 22.5dB-24dB when the SNR is -20dB and the acquisition probability requirement is 96.31% due to the extension of the detection time, compared with the traditional FH synchronization acquisition method.","PeriodicalId":11452,"journal":{"name":"e Informatica Softw.

Testing model transformation is an important activity to ensure the quality and correctness of the generated models. However, during the evolution and maintenance of these model transformation programs, frequently testing them by running a large number of test cases can be costly. Regression test selection is a form of testing, which selects tests from an existing test suite to test a modified program. Aim: The aim of the paper is to present a test selection approach for the regression testing of model transformations. The selected test case suite should be smaller in size than the full test suite, thereby reducing the testing overhead, while at the same time the fault detection capability of the full test suite should not be compromised. Method: approach is based on the use of a traceability mapping of test cases with their corresponding rules to select the affected test items. The approach is complemented with a tool that automates the proposed process. Results: Our experiments show that the proposed approach succeeds in reducing the size of the selected test case suite, and hence its execution time, while not compromising the fault detection capability of the full test suite. Conclusion: The experimental results confirm that our regression test selection approach is cost-effective compared to a retest strategy.","PeriodicalId":11452,"journal":{"name":"e Informatica Softw.

Although many studies have been globally conducted on the different facets of RE in software engineering, studies explicitly focusing on the countries of the Gulf Cooperation Council (GCC) have been scarce. GCC-specific RE research studies are needed because of the unique cultural characteristics and common work ethics in GCC countries. Besides, the investigation of the state of RE practices in the countries of the GCC is crucial as the globalization of software development becomes imminent. This study compares the state of RE practices within the six countries of the GCC, namely, the Kingdom of Saudi Arabia (KSA), the United Arab Emirates (UAE), Qatar, Kuwait, Bahrain, and Oman, using six RE factors. To understand commonalities and differences in the RE practices and methods, 163 software practitioners in GCC countries are surveyed in this study. The results show that the RE practices are relatively similar among the six countries, with subtle differences. Initiating software-related projects with unclear requirements and undefined project scopes are the two major limitations of the RE practices among the survey participants. The results of this study contribute to providing project managers and system analysts, who are working globally and within the GCC countries, with valuable decision-making tools to help them consider the identified RE techniques, methods, and challenges and their related risks early in their software development projects","PeriodicalId":11452,"journal":{"name":"e Informatica Softw.

The way to analyze and obtain effective information from these sparse data is a difficulty in research. As the foundation of analyzing huge amount of biomedical text data, Named Entity Recognition (NER) is essential in Natural Language Processing (NLP) complementing with effective labeling data. One of the two basic sequence labeling methods is rule-based bulk corpus tagging, requiring domain experts to establish targeted recognition rule base. However, in the application field, this method is single, and the portability does not make the expectation, bringing great limitations; The other is complete manual labeling, but it is time-consuming and laborious. Based on Bidirectional Long Short-Term Memory network (BiLSTM), Iterated Dilated Convolution Neural Network (IDCNN) and Conditional Random Field (CRF), we proposed the BIC model. This paper proposes a method for EMR entity labeling based on BIC model, realizing automatic annotation of Chinese EMR data. Machine labeling data can be used after manual review, which will reduce the workload of manual labeling bestially. Compared with other models, F1 value of BIC model reached 91.90% in CCKS2017 dataset, and 78% in PACS report data. Experiments show that our method is superior to the others.","PeriodicalId":11452,"journal":{"name":"e Informatica Softw. Eng.
