The module is part of a bigger project whose goal is that of creating virtual and truly realistic characters capable of interacting with human users. An example of such a virtual character is a computer rendered museum clerk that interacts with visitors. The role of the security module in the envisioned scenarios is that of providing trust, mainly regarding the identity of the human user, but also about the “identity” of the virtual character. In this paper we design (and describe the implementation) of an architecture in which human users identities are checked through face recognition and handled with verifiable credentials managed through a public blockchain. The project has been funded by the European Union and is under realization.","PeriodicalId":131284,"journal":{"name":"2021 7th International Conference on Systems and Informatics (ICSAI)","volume":"128 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117110552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, qualifying the frequency regulation capacity of RES is indispensable. However, the diversity of the control strategies deployed for wind turbines makes it hard to explicitly formulate the frequency regulation model. In this paper, Sparse Identification of Nonlinear Dynamics (SINDy), a data-driven method is employed to identify the aggregated frequency regulation model of wind farms, which can be represented as an equivalent governor transfer function. Compared with physical modelling approach which needs to know all the control parameters in advance, this data-driven method can learn the model characteristics of dynamic systems from the historical data using a universal framework. Numerical simulations indicate that the proposed general frequency regulation model identification framework is applicable to wind farms with high accuracy.","PeriodicalId":131284,"journal":{"name":"2021 7th International Conference on Systems and Informatics (ICSAI)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121857497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, a multi-task information extraction training dataset for bridge inspection is constructed and a distributed representation of the text is obtained using BERT as the embedding layer. Secondly, the subtasks of topic word detection and other bridge inspection information extraction are jointly learned by sharing BERT weights and fine-tuning, and the context features are further extracted in depth. Finally, the bridge inspection knowledge service is used as application examples to verify the effectiveness of the bridge inspection information extraction model in actual application scenarios such as bridge domain question answering. In the comparison experiments with mainstream models, the proposed method outperforms the mainstream models with F1-score of 85.27%, 72.73%, and 90.76% for the NER, RE, and topic word detection respectively.

This brief proposes a new meta-heuristic algorithm, called cuckoo-beetle swarm search (CBSS) to handle this issue in nonlinear optimization. The proposed algorithm imitates the breeding habits of cuckoos and the food foraging characteristics of beetles. Levy flight is combined with particle search velocity to improve the global optimization of CBSS. Nonlinear benchmark functions are tested to verify the accuracy, search speed, and stability of the CBSS algorithm. The numerical verification proves that the proposed algorithm has better robustness and global search capability than its counterparts.","PeriodicalId":131284,"journal":{"name":"2021 7th International Conference on Systems and Informatics (ICSAI)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127125696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is faced with the problems of how to achieve coverage with high frequency, long duration, and fully autonomous for a sudden ground target. Given the difficulty of the conventional constellation to achieve the above capabilities at a lower cost, a broken-chain constellation is proposed. The broken-chain constellation maintains a chain-like configuration in space to achieve better coverage uniformity, which can reduce the number of satellites. Aiming at the fully autonomous operation of the constellation, a distributed autonomous scheduling strategy is designed considering the chain-like characteristics. Compared with the traditional centralized scheduling method, this strategy not only effectively reduces the computational cost but also improves the dynamic response to the observation of sudden ground targets.","PeriodicalId":131284,"journal":{"name":"2021 7th International Conference on Systems and Informatics (ICSAI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124096436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is involved in both simple and complex systems, continuous systems and discrete systems. Of course, the theory of zero-input response in continuous lumped parameter linear time invariant systems (continuous LTI systems for short) is the basis. In the current general theory, the zero-input response of continuous LTI system is considered to be determined by the differential equation and 0− state of the system. However, this paper demonstrates that the zero-input response of continuous LTI system is related not only to the differential equation and 0− state of the system, but also to the input signal expression of the system for time $mathrm{t} < 0$.
