Hence, green dynamic bandwidth allocation (DBA) has been investigated widely. Nevertheless, few of these schemes can support latency-sensitive services while reducing the energy consumption. In this paper, an energy-efficient low-latency DBA scheme is introduced, which is based on a pairwise combination (PWC) method. The proposed scheme can dynamically adjust polling sequence to compact the cycle length, which improves latency performance. What's more, it can enhance the PON energy efficiency in case that both the US and DS transmission are considered. The simulation results show that the PWC-based DBA scheme can simultaneously reduce the energy consumption and improve packet latency.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123723133","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}

But the existing models or algorithms are too complex for actual applications and their real-time performance have not been effectively verified. In this paper, we propose a concise and effective CNN model with only five convolutional layers. Our proposed model allows the input image to be of any size or resolution. The model maps the input image to its crowd density map. By integrating the density map we can get the crowd count. The true density map is computed based on geometry-adaptive kernels which can alleviate the perspective problems. We report the performance in terms of mean absolute error, which is a measure of accuracy of the method. We conduct extensive experiments on major crowd counting datasets to verify the effectiveness of the proposed model and apply it to the actual situation successfully. In addition, we created a new dataset to verify the transfer learning performance and real-time performance of our model. Experiments show that it has great transfer learning performance and real-time performance.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117021180","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}

As a consecutive longitudinal microstructured optical fiber, the DMOF contains backscattering enhanced points which greatly improved the signal to noise ratio(SNR) of the acoustic sensing signal. Based on coherent OTDR demodulation method, the amount of phase change caused by sound pressure can be directly obtained. In order to increase the phase sensitivity, sensing fiber between two backscattering enhanced points along the DMOF is wrapped on a hollow cylinder transducer as an acoustic sensing unit. Finally, experiments on detecting sound waves in air are carried out. The results demonstrate that our fiber acoustic sensor has a flat sensitivity frequency response from 500Hz to 5kHz with a phase sensitivity of around -112dB(re rad/μPa) and a peak sensitivity of -83.7dB at 80Hz. It is noteworthy that the sensing mechanism based on the DMOF can be further extended to distributed acoustic sensing.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116419540","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}

The distributed database is faced with the challenge of data inconsistency due to the complexity of the local database that makes up the distributed database, such as physical location decentralization, different operating systems on the underlying layer and the different ISPs on the network, so this paper designs a distributed message middleware to synchronize heterogeneous database. The paper presents a method of capturing incremental data based on triggers and log tables to get dynamic incremental data after DML operations on the source database. The paper presents a reliable and real-time message transmission mechanism to guarantee the reliability of the message, namely the order consistency and the exactly-once semantics in the process of message transmission. The paper presents a method of generating full data based on real-time computation of incremental data to achieve the high scalability of the destination database and the high availability of the source database service. It can be seen that the paper designs a highly message-oriented reliable, highly architecture-oriented scalable and highly service-based available distributed message middleware to realize heterogeneous databases synchronization. Based on this distributed middleware, this paper designs and implements a prototype system named SUNVE that supports synchronization service from Oracle to PostgreSQL. The final test shows that: SUNVE strictly guarantees the data consistency between the destination database and the source database. The message transmission of SUNVE is the timeliest and its speed is nearly 2 times to that of Kafka and RocketMQ.","PeriodicalId":367029,"journal":{"name":"2018 10th International Conference on Advanced Infocomm Technology (ICAIT)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127573857","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}
