The water samples were collected from two sub-districts, Kwae-Om sub-district and Wat-Pradu sub-district. Twenty sample sites were identified for each sub-district. Samples were taken between October 2018 to September 2019 to analyze for DO (Dissolved oxygen), BOD (Biochemical Oxygen Demand), TCB (Total Coliform Bacteria), FCB (Fecal Coliform Bacteria), and NH3-n (Ammonia). These parameters were used to calculate Water Quality Index (WQI), which is the water quality standard issued by the Pollution Control Department of Thailand. In Wat-Pradu sub-district, the results showed that average water quality from residential area including DO, BOD, TCB and FCB were all in class 4 (deteriorated) except for NH3-n that was below the standard. Water quality from agricultural area including DO, TCB and FCB were in class 4 (deteriorated) while BOD was in class 3 (fair) and 4 (deteriorated) and NH3-n was below the standard. In Kwae-Om sub-district, the results showed that all average water quality from both residential and agricultural area were in class 4 (deteriorated). After converting water quality parameters to WQI, it was found that water quality from residential and agricultural area of both sub-districts were all in deteriorated level (WQI = 31-60). The comparison of WQI between residential and agricultural land uses indicated WQI from both land use types in Wat-Pradu sub-district were not significantly different (Sig 0.086) as well as Kwae-Om sub-district (Sig 0.962) at a significance level of 0.05.","PeriodicalId":147960,"journal":{"name":"Proceedings of the 2020 The 9th International Conference on Informatics, Environment, Energy and Applications","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124011416","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}

As part of the concept on the network security implementation, the CIA triad was tackled which concerns about confidentiality, integrity and availability of data and information. The conduct of this study used a literature review about network underlying threats. After identifying the underlying network threats, a thorough discussion on the available preventive measures that combat network security threats were carried out.

This phenomenon usually occurs due to any switching, interrupting, short-circuiting as well as any rapid changes in the structure of an electrical circuit. To avoid any damage in certain components resulting from the transient, it is important to analyze the change of voltage or current across the circuit elements. This paper studies the transient analysis of a second order RLC circuit that consists of resistors (R) and two energy storage elements, which are inductor (L) and capacitor (C). Such circuit is normally represented in the form of second order ordinary differential equations (ODEs) and such problems are not easily solved analytically. Therefore, a numerical method, namely block backward differentiation formula (BBDF) is applied for solving the ODEs by taking into consideration the damping factor and change in charge with respect to time. This method has the advantage that in each application, the solution is computed at two points simultaneously, which can give faster solutions to the problem. Numerical experiments are carried out to evaluate the capability of the proposed method. It is shown that the numerical solutions approximate the analytical solutions. The performance of the BBDF is compared with the Euler's method, Heun's method and Runge-Kutta method in terms of accuracy. Results obtained show that the proposed method is reliable for transient analysis of electrical circuit due to its comparable degree of accuracy.","PeriodicalId":147960,"journal":{"name":"Proceedings of the 2020 The 9th International Conference on Informatics, Environment, Energy and Applications","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125465813","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}

Today, the increasing demand for energy of the countries that consider their economic growth has increased their energy consumption. This has led to a global energy crisis. The rapid depletion of energy resources in the world has led countries to look for new resources. The necessity of sustainable energy has made renewable resources a new target. At this point, the selection of the best energy technology becomes important. Hence, this study aims to select the most appropriate sustainable energy technology with multi-criteria decision-making (MCDM) methods. The evaluation criteria with quantitative and qualitative characteristics are determined through a literature survey and with the opinions of industrial experts. The process of calculating the weights of the evaluation criteria and choosing the most appropriate alternative is a decision-making process. Decision-making processes based on the opinions of decision-makers, real-life problems, and their complexity include perceptual differences and uncertainties. Hence, the classical MCDM methods have been extended to fuzzy sets in order to eliminate the uncertainty caused by this perception-based fuzziness. The weights of the evaluation criteria are calculated by fuzzy AHP (Analytical Hierarchy Process) method. The most appropriate alternative is then selected using among candidate energy technologies with fuzzy VIKOR (Vise Kriterijumska Optimizacija I Kompromisno Resenje) method. Finally, a case study is conducted to validate the proposed model. To compare the results, the fuzzy TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) method is utilized.","PeriodicalId":147960,"journal":{"name":"Proceedings of the 2020 The 9th International Conference on Informatics, Environment, Energy and Applications","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115552518","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}
