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...

The research summarized and validated the individual selection of camu-camu (Myrciaria dubia (Kunth) McVaugh) plants. 43 progenies, previously selected in genetic tests and fields of producers of flood areas, were evaluated. Each progeny was installed in a row of 10 half-sister plants, with a space of 3x2 m. Using the SELEGEN (Reml / Blup) Model 63 program, four crops were analyzed, and individuals were selected for each of the 16 descriptors evaluated. For fruit yield, the Tipishca-Río Tigre population stood out, occupying 5 of the first 10 places. The individuals TT0725-4 (Tigre-Tipishca) turned out to be a natural recombinant for fruit yield / weight. And individual 64-8 turned out to be triple recombinant (yield / fruit weight / ascorbic acid). The descriptors with the highest genetic control with r ≥ 0.30 were: average fruit weight, brix degrees, plant height, number of basal bra...

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

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...

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...
