The United Nations Organization predicts that 44% of the world population will live a severe water scarcity, in 2050. Countries located in sub-humid and semi-arid regions of the world will be especially concerned by this problematic. Water disinfection by Ultraviolet (UV) radiation is a rising technique in water treatments considering its simplicity and the weak risk of toxic byproducts formation. When UV radiation is absorbed by the cells of microorganisms, it damages the genetic material (DNA) within the cell in such a way that the organisms are no longer able to grow or reproduce, thus preventing the human illness cryptosporidiosis. DNA damage mainly results from irradiation at wavelengths within the UV-C region of the spectrum (200-280 nm) and is maximised at around 254 nm. This is the principle by which UV is used for disinfection. Time required to achieve a total disinfection depends both on the quality of water and the intensity of irradiation. Effective disinfection can be provided by a suitable intensity and duration of UV radiation to give a UV \"dose\" usually expressed in mJ/cm2 (= mW second/cm2, the product of UV intensity in mW/cm2 and contact time in seconds). The target dose will depend on the application, but a dose of 40 mJ/cm2 is commonly used for UV disinfection systems, validated for the broad spectrum inactivation of possible waterborne pathogens such as bacteria, viruses and protozoan parasites such as Cryptosporidium. The objective of this study is to present the state of art of different methods of intensity measurement and modeling, and the use of MPSS model to evaluate the UV intensity distribution inside the photoreactor.","PeriodicalId":416001,"journal":{"name":"Proceedings of the The International Conference on Engineering & MIS 2015","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124371225","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 order to prevent damage of the electrical energy distribution infrastructure, companies typically use transformers with digital meters that allow monitoring in real time, certain parameters like the amount of transformed energy. In several underdeveloped countries as Paraguay, the meters are installed only on a limited number of key transformers. Therefore, it is necessary to estimate the power consumption for the unmetered transformers using existing measurements. For this aim, this paper proposes the application of Linear Genetic Programming (LGP) to find good estimates of the power consumption of unmetered transformers. The proposal is compared with an analytical consumption estimation model proposed in a previous related work, being 13% better on average and 41% better in the best case. Dimensionality reduction proves to be useful to speed up calculation without losing much precision in the LGP estimations.","PeriodicalId":416001,"journal":{"name":"Proceedings of the The International Conference on Engineering & MIS 2015","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131452585","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}

However, computation of the algorithm could be costly and slow in solving problems involving computation intensive, Expensive Black Box (EBB) function due to the high number of objective function evolution required. This work proposes a new strategy which integrates meta-modeling techniques with DIRECT for solving EBB problems. The principal idea of the new approach is to use meta-modeling techniques, such as Kriging, to assist DIRECT to identify the optimum with less number of function evolutions. Specifically, the new approach starts with DIRECT search with a number of iterations and then uses the resulting points in Kriging to construct the meta-model. The best point predicted by Kriging search will then be used by DIRECT as new initial point. As a result, the entire search domain will gradually shrink to the region enclosing the possible optimum. Several runs are carried out to avoid high number of function evaluations to obtain the approximation solution at each stage. The newly proposed method has been tested using ten commonly used benchmark functions. All these tests showed significant improvements over the original DIRECT for EBB design problems.","PeriodicalId":416001,"journal":{"name":"Proceedings of the The International Conference on Engineering & MIS 2015","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133975539","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}

A good understanding of chemical, physical and mechanical processes of the operating system and related equations are needed to model fuel cells, which are hard to determine in many cases. Artificial intelligence (AI) is a choice to overcome this difficulty instead of costly experiments. AI systems such as artificial neural networks (ANNs) have been employed to solve, predict and optimize the engineering problems in the last decade. In the present study, capabilities of ANN to predict the performance of proton exchange membrane fuel cell (PEMFC) considering the cathode electrocatlyst layer degradation is investigated. Experimental data are utilized for training and testing the networks. Current density, temperature, humidity, number of potential cycles, Platinum load and fuel/oxidant flow rates, potential cycle time step are considered as the inputs and the cell potential, Platinum mass loss percentage of the cathode and location of Platinum particles, which are diffused into membrane and deposited there, are regarded as outputs of ANNs. Back propagation (BP) algorithm has been used to train the network. It is observed that when the networks tuned finely, the obtained results from modeling are in good agreement with the experimental data and achieved responses of ANN are acceptable.","PeriodicalId":416001,"journal":{"name":"Proceedings of the The International Conference on Engineering & MIS 2015","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115868537","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}

Conventional frequent pattern algorithms are not applicable to find temporal frequent items from the temporal databases. Given a reference support time sequence, the problem of mining similar temporal association patterns has been the current interest among the researchers working in the area of temporal databases. The main objective of this research is to propose and validate the suitability of Gaussian distribution based dissimilarity measure to find similar and dissimilar temporal association patterns of interest. The measure designed serves as similarity measure for finding the similar temporal association patterns. Finally, in this research, we consider the problem of mining similarity profiled temporal patterns from the set of time stamped transaction of temporal database using proposed measure. We show using a case study how the proposed dissimilarity measure may be used to find the temporal frequent patterns and compare the same with the work carried in the literature. The proposed measure has the fixed lower bound and upper bound values as 0 and 1 respectively which is its advantage as compared to Euclidean distance measure which has no fixed upper bound.","PeriodicalId":416001,"journal":{"name":"Proceedings of the The International Conference on Engineering & MIS 2015","volume":"34 21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132828744","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}
