Los módulos comerciales para el aprendizaje de sistemas de control avanzados no son muy comunes y algunos son muy costosos debido a sus sensores, electrónica y licencia. Hay un área abierta para desarrollar y construir módulos didácticos para mejorar el proceso de aprendizaje mediante la experimentación en sistemas físicos reales. En particular, el péndulo invertido de carro es un sistema físico clásico muy utilizado en las últimas décadas. Proponemos un péndulo invertido de carro llamado MoDiCA-X como un módulo didáctico de bajo costo con hardware y software de código abierto. Es un sistema electromecánico factible de construir y fácil de modificar. Las partes mecánicas del módulo son sólidos impresos en 3D y también se pueden replicar fácilmente. En cuanto a la programación, se puede modificar el control aplicado al sistema, ya que utiliza lenguajes de programac...

The increase of metals in fresh water systems due to anthropogenic activities cause important alterations on the biota. The present review analyze the adverse effects of various metals of ecotoxicological relevance on microcrustaceans zooplankton species (cladocerans and copepods), the experimental advances and the advantages of each group as test organisms. In general, the need to obtain more sensitive and representative indicators than the tradicional ones leads to subchronic, interespecific and multigenerational studies. Additionally, the analysis of mixtures as well as their indirect effects allows to acquire more integral knowledges of the impact of contaminants. The toxic effects are different, depending on the nature of metals, the physicochemical characteristics of the water, exposutre time and genetic traits. However, most works are focused on few species, leading vacant areas o...

Investigation developed with the purpose of knowing which are the main factors that render ineffective the anticipated proof in the crime of sexual indemnity specifically in the declaration that the victim offers through his request by the legitimate parties. Mixed type research with a non-experimental observational design and a descriptive level. The intentional sample was made up of 67 lawyers and 2 prosecutors in which they were interviewed using the semi-structured interview guide. To the main conclusions is that there was a divergence of considerations on the part of lawyers and prosecutors. Prosecutors believe that Article 242 should be amended in order for there to be an update. The non-use of the criminal procedural rule and the fiscal and defense strategy on the theory of the case are the main influencing factors

The results of our recent research work on enterotoxemia in Peruvian alpacas are presented. Microbiological and molecular analyses found that the majority of the isolates corresponded to Clostridium perfringens and contained the cpa coding gene for α toxin (A genotype) while 0.4% contained both the cpa and cpb genes of the α and β toxins (C genotype). A parallel study revealed that 8.5% of the genotype A isolates also had cpb2, but the cpe (enterotoxin) gene was absent in all cases. These results highly suggest that the exotoxins secreted by C. perfringens are the virulent factors in enterotoxemia, rather than the endogenous enterotoxin. Additionally, an histopathological study of intestinal samples from fatal cases showed that 30.6% had abundant immature structures of Eimeria macusaniensis affecting deep mucosa and cryptic gland epithelia, primarily in the jejune and ileum, suggestin...

Abstract — In this project, a design for an automated mechanism is presented for implementation in textile manufacturing processes, where an integrated system for textile fiber recognition based on artificial intelligence (AI) was added. The mechanical design of the machine was studied in terms of force, providing a robust and efficient structure that supports the integration of sensors and cameras for real - time image capture of the processed fibers. Additionally, this design included a precise feeding system and a transport mechanism that ensured the stability and correct positioning of the fibers during analysis. In parallel, an AI model was implemented to identify and classify textile fibers based on their color characteristics. A simulated dataset was generated , where each type of fiber was represented by a specific color (red, green, blue, yellow), and a simple neural network w...

Throughout this thesis, advanced numerical tools and laboratory tests are investigated that will allow an accurate prediction of the global nonlinear structural response of hybrid timber-steel connections under cyclic loading. The conceptual development of the model, its mathematical formulation, numerical coding and implementation in a commercial FE software are documented in this thesis. Furthermore, the proposed timber material model has been developed within the framework of the Continuum Damage Mechanics (CDM) theory, making it ideal for damage evolution modelling and behaviour-based seismic assessment of timber structures. Experimental studies available in the literature were employed to assess the accuracy and overall performance of the proposed constitutive model at the material and structural (or component) level. Additional local responses not easily identifiable from the exper...

«in vitro & in vivo» studies of fue Anti-A Experimental Paste, with the help of Sangre de grado and tricalcic phosphate, they have shown an excellent capacity germicide and reparative of the conjunctive tissue. The fibroblástic activity observed in most of the cases, probably generated by effects of the tricálcic phosphate, is the same one that showed a similar behavior in a previous investigation, inducing the reparative process of the bony defects. However, the application of the Anti-A Experimental Paste in human in posexodoncic ad that showed dilution with the saliva and lack of adhesion tissue, believe the necessity to continue with the investigation line with the purpose of improving their original properties, incorporating biocompatible additives. the study consisted on elaborating 8 pastes with diverse formulations with the help of Sangre de grado, tricálcic phosphate, r...

Wheat (Triticum aestivum L.) sustains global caloric intake, but its productivity in Andean highlands is constrained by soil fertility and input reliance. This study represents one of the first field-based evaluations of biofertilizers under high-altitude, rainfed Andean conditions, addressing a major knowledge gap in low-input mountain agroecosystems. This study evaluated three seed-applied biofertilizers—Azospirillum brasilense, Trichoderma viride (Trichomax), and an anchovy (Engraulis ringens) based liquid biofertilizer, compared with an untreated control and a soil-test mineral fertilization benchmark in rainfed wheat (Triticum aestivum L.) cv. INIA 405 in the central Andes of Peru. A 5 × 5 Latin square design (25 plots) was established under farmer-realistic conditions. At physiological maturity (Zadoks 9.5), plant height, spike length, grains per spike, thousand-grain weight, te...

The task of elaborating accurate test suites for program testing can be an extensive computational work. Mutation testing is not immune to the problem of being a computational and time-consuming task so that it has found relief in the use of heuristic techniques. The use of Genetic Algorithms in mutation testing has proved to be useful for probing test suites, but it has mainly been enclosed only in the field of imperative programming paradigms. Therefore, we decided to test the feasibility of using Genetic Algorithms for performing mutation testing in functional programming environments. We tested our proposal by making a graph representations of four different functional programs and applied a Genetic Algorithm to generate a population of mutant programs. We found that it is possible to obtain a set of mutants that could find flaws in test suites in functional programming languages. Ad...
