This paper uses descriptive statistics, SFA and multivariable regression based on primary datacollected from 160 farmers applying these two irrigation models in Cau Ngang and Duyen Hai districts. The study found that the cost of plant variety, the amount of phosphorus, costs for post-harvesting, labor and irrigation affected the productivity of watermelon in the traditional flooding irrigation model; whereas the amount of potassium, the amount of phosphorus and cost of plant variety were factors affecting the productivity of watermelon in the drip irrigation model. Theresults also showed that producers applying the drip irrigation model achieved higher technical efficiency. The average efficiency levels achieved were 79,47% and 86,03% in the traditional flooding irrigation and drip irrigation respectively. In addition, the factors affecting the income of farmers in the traditional flooding irrigation model included household labor, loans, the amount of phosphorus, the amount of potassium, and cost of pesticides and irrigation. Meanwhile, the income of farmers in the drip irrigation model was affected by education, training, costs for post-harvesting and loans.","PeriodicalId":21692,"journal":{"name":"Scientific Journal of Tra Vinh University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84701632","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 average length and weight  of the rice eels were 22.28 ± 0.21 cm/inds and 14.65 ± 0.48 g/inds, respectively. The experiment was conducted with two treatments: the control treatment and the recirculation treatment; each of them was repeated 3 times in 180 days. Rice eel was fed with 80% fresh trash fish and 20% pelleted pellets with 30% protein. The results showed that the environmental factors such as temperature, pH, N-NH3-, N-NO2- and alkalinity were in suitable range for rice eel growth during the experiment. The survival rate was not different between the two treatments. Weight growth rate in the recirculation system (97.70 ± 9.04 g/inds) was higher than the control (80.67 ± 0.16 g/inds) (p<0,05). Feed conversion ratio (FCR) in two treatments was not different with 2.49 ± 0.05% and 2.41 ± 0.22%. The amount of water was added in recirculation system (3.12 m3/tank) during 180 days only 1/10 compared with thecontrol (32.8 m3/tank).

Unfortunately, the duplicatebug report problem arises because there are too many duplicate bug reports in various software projects. Handling with duplicate bug reports is thus time-consuming and has high cost of software maintenance. Therefore, this research introduces a detection scheme based on the extended class centroid information (ECCI) to enhance thedetection performance. This method is extended from the previous one, which used only centroid method without considering the effects of both inner and inter class. Besides, this method also improved the previous use of normalized cosine in identifying the similarity between two bug reports by denormalized cosine.  The effectiveness of ECCI is proved through the empirical study with three open-source projects: SVN, Argo UML and Apache. The experimental results show thatECCI outperforms other detection schemes by about 10% in all cases.","PeriodicalId":21692,"journal":{"name":"Scientific Journal of Tra Vinh University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84309126","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}
