The unstable effects of the surrounding environment and the internal adjustment of the project lead to many fundamental changes that were initially planned and changed the effectiveness of the project. This is the existence of the risk of Public Private Partnerships (PPP) project in investerment of technical infrastructure in Da Nang. Risk management is an important issue when implementing a PPP project, especially PPP in technical infrastructure projects. This study focused on the survey methodology of all PPP stakeholders in Da Nang in order to examine PPP awareness and risk management awareness for successful implementation of PPP projects. Thereby, an effort is also made to investigate the experts which to identify the seriousness of the risks associated with PPP. Based on the results of the survey, risk mitigation measures were proposed for significant risk factors in PPP projects in Da Nang of technical infrastructure investment, which facilitated the development of a project sustainable in today which uncertain environment.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"306 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":"115256319","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}

In fact, a microgrid system is a small-scale of a distribution system including three main elements: (i) distributed resources, (ii) storage system, and (iii) measurement system. The main purpose of a microgrid system is ensuring the continuous supply energy in a small or isolated area, thus it has two main operation modes: (i) independent and (ii) connected to the main power grid. One of the main challenges of the operation of a microgrid system is the smooth and optimal shift between these two operation modes in cases of any contingencies from both sides. Thus, the operation of a microgrid system requires designing various advanced control methods for this activity, in which the hierarchical control technique is widely using in the real application. Therefore, an overview of this method is very necessary for the research community since there are many works have done in recent years. In this paper, the authors present the hierarchical control technique and focus on investigating various methods of the primary control of this technique because this level is responsible for the independent operation mode of a microgrid system known as the main advantage of a microgrid system.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"22 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":"125911512","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 paper aims to design and optimize the proposed stage. The working travel of proposed stage is amplified via using the four-lever amplification mechanism. To improve the performances of the stage, the geometric parameters are optimized by an integration method of Taguchi method (TM), response surface method (RSM) and nondominated sorting genetic algorithm II (NSGA-II). Firstly, the number of experiment of four design variables were created by the TM. Subsequently, the output displacement and the first natural frequency are retrieved by finite element analysis (FEA). Then, the mathematical equations between four design variables and both responses is established by using the RSM. Eventually, based on mathematical equations, the NSGA-II is adopted to determine the optimal parameters. The results indicated that the optimized y-axis displacement was about 3.862 mm and the first natural frequency was approximately 45.983. The results of FEA validations are in a good agreement with the predicted results from the proposed approach. This result indicated that the integrated proposed approach ensures a high reliability for engineering optimization problems.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"23 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":"127028089","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}

It conducted the fish skin purification method by LasNa 0.5% in NaOH 1% during 8 hours, and then the collagen was isolated from purified fish skin by acetic acid. At the same time, the optimization method was used to describe the extraction process of collagen with the objective function (y) and three factors which affected the objective function were the ratio of acetic acid to fish skin (x1), concentration of acetic acid (x2), and extraction time of collagen (x3). The quadratic polynomial optimization model y has been used to create response surface for extraction efficiency of collagen. Under these conditions: the ratio of acetic acid to fish skin was 13/1, the concentration of acetic acid was 0.58M and the extraction time was 26 hours, the collagen extraction efficiency achieved maximum value of 72.9%. This result was the scientific basis to choose the extraction conditions in technology producing collagen from fish skin in order to get the high quality product. The final product had white colour, soft fibre structure to meet the collagen quality in food.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"140 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":"131860873","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}
