Full Rank Cholesky Factorization for the Re-Weighted Least Squares Applications

Factorization of matrices are required frequently in sciences research, in order to simplify computations when solving linear or non-linear systems of equations. In particular, these systems arise in data analysis and also after modeling industrial process, playing an important role in the final solution. When the matrices involved are full rank and squared classical factorizations can be used efficiently. However, when one has to deal with rectangular and/or rank deficient matrices, extensions of these factorizations should be considered, if it is possible with the same good properties. Objective: In this work a full rank Cholesky factorization for rank deficient matrices is described, along with its use in a particular application arising in Statistics, where usually one has to solve overdetermined systems of equations via least squared method or its extensions. Methodology: We describe an algorithm to generate this factorization in an iteratively reweighed least squared method applied to maximum likelihood parameters estimation. Results: Preliminary experiments are presented over synthetic data, supporting the use of this decomposition for rectangular or rank deficient matrices arising in similar applications. Conclusions: The proposal of using the full rank Cholesky factorization in the iteratively reweighted least squared to estimate maximum likehood parameters is promising and could be used to improve CPU time in the solution of similar problems.

Fuel consumption and pollutant emissions analysis at different proportions and lubricating oils brands for two-stroke engines using extra and super gasoline

The consumption of extra and super fuels in combination with three brands of oils A, B and C, and the exhaust gas emissions in a 171cc two-stroke engine were analyzed at different proportions. First, three brands of coded oils were defined as, A (Motorex), B (Golden Bear) and C (Motul), and the extra and super fuels. Each brand of oil was mixed with the two types of gasoline, applying a mixture formula with the help of the oil manufacturer's manual and laboratory equipment to obtain exact quantities, thus obtaining six different mixtures or combinations. For fuel consumption tests, 5 samples were taken from each combination and the two-stroke engine was run at idle for 20 minutes and the consumption of each combination was determined, resulting in the C oil (Motul) whose 25: 1 ratio, generates lower fuel consumption. For the exhaust gas analysis, the free acceleration method of the INEN 2202 standard was applied, which allowed observing the coloration and opacity of the exhaust gases of each mixture, resulting in C Oil (Motul) reducing fuel consumption. and it has an average opacity of 60% if it is mixed with the extra gasoline, in turn, said opacity is reduced to 40% when the mixture is with the super gasoline. The consumption results were contrasted with the ANOVA statistical test in MINITAB obtaining a p value (1.617E-20) <α (0.05) accepting the alternative hypothesis, supported by a qualitative analysis for the gas results

Cortometraje animado en software 2D “Quinua del viento”

Introduction This study focuses on the production of an animated short film about the quinoa production process. Until now, dedicated efforts have made it possible to position quinoa as a superfood with great nutritional potential, leaving aside its cultural and historical value. Objective Therefore, the main objective of the short film is the revaluation of quinoa as an ancestral grain, which aims to motivate its cultivation and consumption from this approach. Methodology Based on the Bruce Archer methodology, which has three phases; analytical, creative, and executive. In that order, it began by collecting information about the origin and production of quinoa through observation files, interviews with experts, quinoa producers, and experts in other areas.  From this investigation, the story developed “Quinoa in the wind”. The last phase was developed, following the typical stages of short film production: pre-production, production, and post-production. Results From the story, the script and storyboard were developed, which served as a visual guide. In the second phase, the Stop Motion technique was used. At this stage, the characters and environments were designed, inspired by indigenous people and settings from the province of Chimborazo. Finally, the 2D animation software “Adobe Premiere Pro” was used for editing and retouching the short film. In addition to this, the musicalization, the selected rhythm was the “Albazo” because it is a musical genre from the Ecuadorian highlands.
