First, we will present the three mathematical models that govern the evolution of the prey relative to the predator and vice versa, the spread of an infectious agent within a population, or even bacterial growth in a given environment. These models form a system of non-linear and coupled equations, which requires special numerical processing because of the biological terms used in these one. The numerical simulation is based on the explicit Runge-Kutter method of order 4 (ODE 45) which is best suited to solve this type of equation system.","PeriodicalId":312521,"journal":{"name":"2019 International Conference on Intelligent Systems and Advanced Computing Sciences (ISACS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114174017","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 special source term approximation, which represents an artificial viscosity, is introduced so that the proposed methods can preserve the still water steady state exactly and acquire Shock-capturing capabilities. Furthermore, the non-negativity of the water height is preserved and the method is well-balanced for the still water steady-state solutions. Promising numerical results are obtained at the end to verify these properties for problems involving transcritical flow.","PeriodicalId":312521,"journal":{"name":"2019 International Conference on Intelligent Systems and Advanced Computing Sciences (ISACS)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127939935","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}

Measuring face characteristics by beauty experts manually costs time and efforts. Therefore, developing automated face shape identification system could alleviate the need for additional time and efforts made by experts. Many automatic face shape classification methods have been proposed in the literature; however, the existing methods tackle many challenges due to the complexity of face geometry and variation in its characteristics. This paper presents a deep convolutional neural network method (CNN) approach for classifying face shape into five types. The proposed method which is based on merging the features learnt by CNN with hand crafted features represented by histogram of oriented gradients (HOG) and facial landmarks has proven to be efficient in identification of facial shape. The obtained results demonstrate that the proposed method is promising in identifying the shape of face achieving accuracy of 81.1%.","PeriodicalId":312521,"journal":{"name":"2019 International Conference on Intelligent Systems and Advanced Computing Sciences (ISACS)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116015080","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 resolution of this system by the iterative method of Newton-Raphson requires at each iteration the factorization of a matrix of the same size and the same structure as the matrix of the system. The storage space required for storage and the machine time required for their factorization become excessive. For industrial problems (3D problems or even in 2D), It is practically impossible to work with matrices, the memory space to store them is out of reach of current computers. To overcome this problem, the linear systems resulting from the Newton-Raphson algorithm are solved by the GMRES (Generalized Minimal RESidual) algorithm. The structure of the GMRES algorithm makes that we never have matrices to evaluate, but only the action of a matrix on a vector. Convergence is accelerated using a pre-conditioning technique. The diagonal pre-conditioning that we have developed is simple and effective.","PeriodicalId":312521,"journal":{"name":"2019 International Conference on Intelligent Systems and Advanced Computing Sciences (ISACS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122195678","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}
