This final project discusses the stability analysis of the SEIR diffusion model on supply chain financing based on blockchain technology. In the observed model, it is shown that the model uses a system of ordinary differential equations with its operational form, namely the company. The company is divided into four compartments, namely non-chain companies, companies that are potentially in the …
This final project discusses the new iterative method using weight function for finding multiple roots of nonlinear equations. The convergence analysis using Taylor expansion and geometric series show that the proposed method has a fifth order convergence. Numerical computational results of some examples with several different types of fifth order methods show that in general the proposed metho…
There are many methods provided by previous authors regarding the application of fuzzy in diagnosing a disease. Generally, the application of fuzzy soft matrices and triangular fuzzy numbers are used separately. Several other authors utilize triangular fuzzy number matrices in diagnosing diseases with arithmetic that produces a˜ × (1/a˜) ̸= ˜i . The diagnosis of disease in this paper is d…
This final project discusses the King multiplicative method (MKP) as a new iteration formula obtained from modification using multiplicative calculus for solving nonlinear equations. Convergence analysis using multiplicative Taylor expansion shows that MKP has a convergence order of four. Then from the results of computational tests through comparison with various fourth order methods it shows …
This final project discusses the application of natural logarithm to the Newton two step method. The method is called the Newton two step method with multiplication calculus. Convergence analysis shows that the MP has order four. Numerical comparison between MP and some known iterative methods shows that MP is better in stability and convergence accuracy in solving nonlinear equations. Keyword…
