The fluid investigated is of sediment/clay suspension exhibiting yield stress characteristics. Bentonite-water suspension 7.5-15wt% and laponite-water suspension 3.5-5wt%, which correspond Bn = 19.76-1470.94 at Re = 100 and Bn = 1.976-147.09 at Re = 1000, are used for simulations. To model the viscoplastic effect, Herschel-Bulkley’s bi-viscosity model for Bingham type is employed. Various flow aspects, i.e., viscosity distribution, streamline pattern, formation of unyielded zones, and pressure distribution, are presented and analyzed in detail. Results show that at Re = 100, neither circulation wake nor static rigid zone is formed in the flow field pattern meanwhile at Re = 1000, the static rigid zone exists at Bn = 6.83 (bentonite 7.5wt%) and Bn = 20.88 (bentonite 10wt%). Moreover, the moving rigid zones generally become larger with the increasing Bn. Furthermore, results for pressure loss per length and friction factor are reported. Approximation functions for pressure loss estimation are also proposed.","PeriodicalId":6690,"journal":{"name":"2020 Applying New Technology in Green Buildings (ATiGB)","volume":"1 1","pages":"87-93"},"PeriodicalIF":0.0,"publicationDate":"2021-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81952300","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}

Several back-calculation programs are useful for back-calculating road pavement layer moduli. A genetic algorithm (GA) was used successfully in this problem but it requires more computation time to a variation of computed deflection using optimized moduli value of road pavement layer based on the GA. There is a few research adopted to Artificial Neural Network (ANN) for computing deflection of the road pavement system. This article aimed to develop ANN for computing surface deflection of pavement using layer moduli and its thicknesses as input parameters. We have also discussed the solution techniques and algorithms for use in developing the program, including Burmister theory for determining deflection based on a cylindrical coordinate system, the GA optimization for back-calculating road pavement moduli, and the development of the ANN-GA model. The evaluation shows that the predicted deflections using the ANN compare well with computed deflections from the hypothetical model. Backcalculated layer moduli based on the GA-ANN model are well with a hypothetical model based on FWD test.","PeriodicalId":6690,"journal":{"name":"2020 Applying New Technology in Green Buildings (ATiGB)","volume":"90 1","pages":"53-59"},"PeriodicalIF":0.0,"publicationDate":"2021-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78666276","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 the domestic demand of using organic fertilizers for clean agriculture is increasing, these organic materials are disposed in a wasteful way. This study indicated that the nitrogen (N) concentration of the waste that include septic tank sludge (STS), food waste (FW) and sludge from seafood waste water treatment plant (SFS) is quite high by 965 mg/L, 34,314 mg/L and 1,756 mg/L. In this study, an Anaerobic Digester_Continuously Stirred Tank Reaction (ADCSTR) system was established to recover the N from these wastes. The ADCSTR was made of 5 mm thick tempered glass, with the dimension of the tank is H x D x R = 1,000 mm x 300 mm x 300 mm. The C/N ratio used for the ADCSTR was 25, which was identified by pre-testing seven small AD systems with different C/N ratios. The result revealed that after 50 d of anaerobic digestion, the Carbon (C) and Nitrogen (N) concentrations of liquid product was 9,628.3 mg/L and 648.5 mg/L, and the carbon to nitrogen ratio (C/N) was 11.35 as well, equivalent to 78.2 % of recovering efficiency. This study also indicated the potential to recover nutrition, produce organic fertilizer from recycling the STS, FW and SFS in Vietnam, significantly contribute to reducing waste to the disposals.","PeriodicalId":6690,"journal":{"name":"2020 Applying New Technology in Green Buildings (ATiGB)","volume":"182 1","pages":"125-129"},"PeriodicalIF":0.0,"publicationDate":"2021-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80334494","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}
