The recent emerging Industrial IoT (IIoT), a sub-paradigm of IoT, focuses more in safety-critical industrial applications. Studies showed that the adoption of BDA increase companies' output and productivity; IoT enables companies to have more information and control in physical resources, processes, and environments; BDA and IIoT complement each other and develop as a double “helix”. In this position paper, we briefly review the opportunities and challenges in this era of big data and IoT for the Møre maritime cluster; then we propose a new framework integrating BDA and IIoT technologies for offshore support vessels (OSVs) based on a hybrid CPU/GPU/FPGA1 high performance computing platform. We believe that such a framework, when implemented, can help maritime companies increase their output and productivity, and hence enable the whole cluster to continue to be a leader in the global maritime industry.","PeriodicalId":22200,"journal":{"name":"TENCON 2015 - 2015 IEEE Region 10 Conference","volume":"10 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86048691","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}

Numerous methods for the analysis of power system harmonics have been developed both in the time domain and frequency domain. The Unified Harmonic Domain algorithm is a frequency domain technique reported to be computationally effective and arrives at an accurate solution. In the characterization of this harmonic analysis technique, there was an opportunity to improve solution convergence by implementing its initialization stage in the time domain. The test system used for this research is the rectifier of the CIGRE HVDC Benchmark Model. Results obtained from the various initialization stage implementations were compared with each other, as well as to a set of results from a PSCAD/EMTDC simulation. Results show that a non-updating Jacobian initialization stage and time domain initialization are promising alternatives to the original implementation.","PeriodicalId":22200,"journal":{"name":"TENCON 2015 - 2015 IEEE Region 10 Conference","volume":"32 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90923506","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}

This STATCOM is applied to compensate reactive current, unbalance current and harmonics in a three-phase three-wire system. In previous work, instantaneous power theory was used to calculate the phase reference current. Zero-sequence injection method was adopted to modify the reference current, so that active power was redistributed among delta-connected clusters for balancing dc voltages. Steinmetz theory is applied to calculate fundamental phase reference current in this paper. The obtained reference current has a 90 degree phase difference with the line voltage. There is no active power exchange between the inverter and grid even unbalance currents are compensated. As a result, the dc voltage of the cascade multilevel converter can be easily balanced. Simulation results are provided to show the effectiveness of the proposed method.","PeriodicalId":22200,"journal":{"name":"TENCON 2015 - 2015 IEEE Region 10 Conference","volume":"44 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73548752","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 implementation of a DC communications bus in the system, for coordination among modules, was demonstrated to be advantageous in speed of recovery from transient irradiance changes during maximum power point tracking, as well as in load sharing control.","PeriodicalId":22200,"journal":{"name":"TENCON 2015 - 2015 IEEE Region 10 Conference","volume":"247 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73512260","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}

Moreover, the push/pull transistors in the proposed circuit can be implemented in identical NMOS transistors, thus releases the stringent transconductance matching requirement at the output stage.

The knowledge and information exchanged between different social networks are important in enhancing user experience. However, sharing information should not be completely barrier free as weak polices and uncontrolled sharing could lead to numerous security risks. Thus, we propose a method to effectively share information in a secure and efficient manner by establishing collaboration between social networks. The proposed method implements sharing components without changing the original data and system structure. Various social networks can be connected to each other; this connection can be referred to as a united social network (USN). Within a USN, each member social network has its own sharing policy and controls its shared information. Any two social networks can initialize communication and mutually determine sharing policies. Then, information can be shared between networks using the proposed schema. A social network user's decisions are involved in each sharing decision. This determines access parameters. Privacy can be systematically preserved by defining subject (requester) attributes, environment attributes, and resource attributes while information is shared among different collaborative social networks.","PeriodicalId":22200,"journal":{"name":"TENCON 2015 - 2015 IEEE Region 10 Conference","volume":"123 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77193556","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}
