A fuzzy system is utilized to approximate an unknown function in the considered Hamiltonian system. In terms of fixed-time stability criterions, a novel controller is presented to stabilize the resulting closed-loop system in fixed-time on a neighborhood of the origin. Moreover, in order to save resources, an event-triggered scheme is established to update the controller according to the trigger conditions. Taking advantage of Lyapunov stability theory, some sufficient conditions are presented to make the system states converge to the origin in a fixed time. At the same time, under the designed controller, there exists a positive lower bound between adjacent trigger times, which means that the Zeno phenomenon is avoided in the proposed event-triggered mechanism. The validity of the designed controller and event-triggered approach is also verified by a circuit system simulation example.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124252781","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}

Owing to the UAV’s limited battery capacity and coverage range, its energy consumption or coverage have been explored by researchers. However, the existing research largely overlooks the tradeoff involved in optimizing UAV swarm deployment for wireless coverage over a ground area. This study considers homogeneous UAV deployment in a 3D space to provide sustainable wireless services as a multi-objective problem. We introduce three objectives: 1) minimize the total energy consumption while deploying a UAV to UAVs on duty, 2) minimize the number of UAVs, and 3) maximize the coverage rate of the target area. With the aim of achieving a better trade-off between these objectives, we adopt the framework of MOEA/D, which allows search progress cooperating with neighboring subproblems each other. Particularly, we introduce a single-tuple encoding scheme and genetic operators (i.e., selection, crossover, and mutation) to generate feasible optimal solutions. The simulations demonstrate that the proposed algorithm is effective and surpasses the improved SPEA II and NSGA II, which indicates that the approach is dependable in solving the proposed multi-objective optimization for UAV deployment.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116262619","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, the end-to-end speech synthesis system based on deep learning has disadvantages such as missing words, repeated pronunciation, and slow synthesis speed. In view of the local information preference of the Tacotron2 model in the decoder, this paper proposes to maximize the interactive information between the text and the predicted acoustic features and use the WaveGlow synthesizer to reduce the local information preference and the problem of slow synthesis speed, pronunciation in the Tacotron2 model. Experimental results show that the improved model subjective evaluation MOS (Mean Opinion Score) score is 3.94, and the synthesis speed is significantly improved.","PeriodicalId":382483,"journal":{"name":"2021 13th International Conference on Advanced Computational Intelligence (ICACI)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128200289","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}

MEC is evolving as a promising technique susceptible to support resource constraint devices and delay sensitive applications, by delivering computing services nearby mobile users. Nevertheless, many studies have shown that latency remains one of the major challenges in MEC networks. However, in this paper, we propose to solve the latency challenge in mobile edge computing by developing the channel allocation-based demand assignment protocol for computation offloading (DAP-CO), and to tackle the server selection problem in a multi-edge server network so that to minimize the execution costs generated by mobile applications computation.
