Business managers recognized that when their companies do CSR, they create a better image in the community and are more well-known than their competitors, therefrom increasing their business performance. However, CSR has become widespread in developed nations but in developing ones like Vietnam, it is a relatively new concept that has not caught much public attention. This paper therefore put forth a conceptual model of CSR for tourist companies in Vietnam. This model shows the relationship between CSR, firm reputation and firm performance. From the proposed model, the following studies may continue to using this model to survey to reinforce its value.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121555261","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 shorter the time of detection of faults is, the faster the recovery of the normal operation of the distribution network is. However, this task contains a challenge due to the complexity of distribution networks that are using both overhead and underground cables. Recently, many research activities are presented to detect the short-circuit fault in a distribution network and classified into three catalogs: (i) time domain reflection, (ii) traveling wave method, and (iii) impedance method. However, the first two methods have a very high investment cost, thus they are not used widely in distribution networks even their efficiency performance is confirmed. Therefore, this paper aims to study on many algorithms; e.g. Tagaki, Saha, Personal Algorithm; which are developed based on the last method, then a program is implemented in Matlab Simulink in order to test various algorithms. Moreover, these algorithms are tested with two real underground cables in the Center of Vietnam to figure out the best algorithm for the real application in Vietnam.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133657484","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}

By smoothing the in-plane strains on sub-triangular domains created by connecting the bubble node to element nodes and applying the divergence theorem to derivatives in the gradient matrices, the integration of corresponding stiffness matrices are transformed from surface to line integrals. To remove the shear locking, the MITC3+ technique for three-node triangular degenerated shell elements with a bubble node is employed. The Craig-Bampton (CB) and enhanced Craig-Bampton (ECB) methods, which are well-known reduced-order modeling techniques based on substructuring strategy, are used for efficiently solving frequency analyses. Numerical results demonstrate the reliability and superiority of the present element, called CS-MITC3+, when combined with the substructuring methods to compute frequencies of plate and shell structures.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117001497","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}

Copper nanoparticles were generated in situ on pieces of commercial polyethylene terephthalte (PET) filter cloth by reducing [Cu(OH)4]2- ions by ascorbic acid in aqueous solution. Elemental analysis using energy-dispersive X-ray (EDX) spectrum of the modified filter fabric confirmed the presence of copper (0.15-0.35 $mu$g/mm2). Analysis of scanning electron microscope (SEM) images showed that the sizes of synthesized copper particles varied from less than 100 nm to over 500 nm. Increasing ascorbic acid concentrations while fixing cuprate ion concentration resulted in higher load and lower sizes of deposited copper nanoparticles. Antibacterial activity of the modified polyester filters was assessed by passing suspensions of Escherichia coli NBRC 14237 in phosphate-buffered saline (PBS) and in sterilized milk through these modified filters. Analyzing the effluent for viable bacteria showed that the antibacterial activity against E.coli in PBS was about 12 times more effective than that in milk. Moreover, increasing copper nanoparticles load on the filter resulted in increasing antibacterial effect toward E.coli. Leaching test showed that concentration of copper in the effluent after passing distilled water (1000 and 2000 m3/m2) through the modified filter was below the recommended limit for copper in drinking water (1 ppm).","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132701280","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}

While electronic devices as well as software have been developed ceaselessly, the technology of battery development does not keep pace. Beside that each sensor node usually uses batteries for power, these sensors often cannot change or recharge in the usual way. In all the operations of a sensor node, wireless communication is the most energy consuming operations. So, in order to extend the life of the battery in the sensor node, we need to limit the transmission of information over the wireless network, however, we must also ensure that the sensor node transmits enough information about the host. We can do this by data compression. We have to choose an efficient and simple data compression algorithm because energy, memory and computational resources of sensor node are very limited. In this article, we adjust a lossless data compression algorithm to suit the wireless sensor network and meet the requirements set forth above. Accompanying that, with the best knowledge we have, we also offer a comparison of the efficiency of this algorithm with two well-known compression algorithms, namely bzip2 and gzip.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128340988","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}
