Some results obtained in the production and maintenance areas were the diversity of items such as tire tubes and car mats;in the maintenance area,it was possible to keep the equipment in optimal operating conditions. As a conclusion with this manual of the IATF 16949-2016 standard,thecompany managed to enter the automotive market sector.

Este trabajo presenta un estudio preliminar sobre la manufactura de piezas metálicas mediante modelado por deposición fundida (FDM) y posterior sinterizado. Se fabricó un engrane de bronce con diámetro exterior de 50 mm, diámetro interior de 15 mm, espesor de 3,85 mm y perforaciones de 3 mm. El proceso incluyó la impresión con filamento compuesto bronce/PLA, debinding y sinterizado en mufla convencional. Durante la impresión se emplearon parámetros de 235 °C de extrusión, 60 °C de cama, 0,20 mm de altura de capa, 40 mm/s de velocidad, 90 % de relleno rectilíneo y 120 % de flujo. Los resultados dimensionales mostraron contracciones de hasta 12 % en el diámetro interior y 34,5 % en perforaciones; el espesor presentó variaciones de −4,67 % a +2,33 %. La dureza Rockwell HRB se ubicó entre 49 y 64. Tras el sinterizado, las piezas conservaron la geometría general, con irregularidades superficiales y porosidad asociadas a la eliminación no controlada del aglutinante. También se imprimieron piezas en acero inoxidable 316L (solo etapa de impresión); el proceso no se completó por limitaciones de temperatura del equipo. Estos hallazgos evidencian la factibilidad del enfoque y la necesidad de estudios adicionales orientados al control de contracción, densificación y acabado superficial.

Uncertain masses, dimensions, and friction coefficients can cause a robot’s motion to differ from predictions based on nominal parameters. This study examines how these uncertainties affect joint trajectories and which parameters deserve closer characterization. Ten physical parameters of a planar two-degree-of-freedom manipulator are represented by triangular fuzzy numbers, defined by lower, nominal, and upper values. Their $\alpha$-cuts form nested parameter intervals, whose vertices are propagated through the nonlinear rigid-body equations to approximate the range of joint responses. Numerical tests use sinusoidal and step torques, different initial conditions, Monte Carlo sampling, and sensitivity analysis. Verification with 50,000 samples per tested domain reveals a small second-joint exceedance under baseline sinusoidal excitation and larger exceedances under step torques; the alternative sinusoidal configuration retains complete sampled containment. Under the baseline sinusoidal excitation, the individual parameter ranking remains unchanged at the four nondegenerate $\alpha$ levels tested; the link length $l_1$, second-joint friction $b_2$, and first-link mass $m_1$ have the largest effects. A reduced-order surrogate also lowers the cost of repeated model evaluation within the tested domain. The contribution is an integrated workflow for assessing response dispersion and prioritizing parameter characterization before controller design or hardware testing. Its envelopes support preliminary model assessment rather than guaranteed response bounds.

The project consists of the design and construction of a biodigester that allows the generation of methane gas for heating and cooking food in domestic stoves. The Biodigestor will have as byproduct Biol, from leached organic matter, this byproduct can be used as fertilizer in gardens or domestic crops. The monitored variables of the Biodigestor use a data acquisition card to obtain the level of Ph, biol, temperature, humidity and pressure during the methane generation process, as well as the quantity and quality of methane gas produced. This project has been developed in several stages, design, prototype scale tests, connection of sensors and tests that allow to define reference data and data during methane production. A design has been achieved that allows simultaneous production in three biodigestors, this proposal will allow through a specific protocol, the continuity in obtaining the gas can be maintained with the possibility of emptying, cleaning and replacing organic matter without stopping the methane production process

Reliable deployment of predictive emission monitoring systems (PEMSs) requires evaluation under future operating conditions and explicit attention to high-emission events. This study presents a pollutant-specific, risk-constrained framework for predicting Gas Turbine CO and ${\mathrm{NO}}_x$ emissions under multiyear distribution shift. A dataset containing 36,733 observations was divided chronologically: 2011–2013 were used for model development, 2014 for configuration selection and calibration, and 2015 as a locked final test. Matched random within-prefix and forward temporal validation were compared, and Extra Trees was selected for both pollutants. Conventional, tail-weighted, covariate-shift-weighted, and combined configurations were evaluated under global-RMSE budgets of 2%, 5%, and 10%. Random within-prefix validation produced RMSE estimates 25.0% lower for CO and 34.0% lower for ${\mathrm{NO}}_x$ than matched temporal validation. In 2015, CO tail weighting produced modest changes, reducing global RMSE by 0.9% and ${\mathrm{Q}}_{99}$ mean underprediction loss by 2.0%, without statistically resolved ${\mathrm{Q}}_{99}$ improvement. For ${\mathrm{NO}}_x$, tail weighting reduced ${\mathrm{Q}}_{99}$ RMSE by up to 5.5% while increasing global RMSE by 5.8%. Linear calibration reduced ${\mathrm{NO}}_x$ global RMSE from 13.246 to 6.333 mg/m³ but worsened ${\mathrm{Q}}_{99}$ RMSE. Overall, temporal generalization, global calibration, and high-emission performance were distinct criteria, and no adaptation strategy was uniformly preferable.
