The Peruvian Arbitration Law was inspired by the UNCITRAL Model Law on International Commercial Arbitration. Both rules empower arbitration tribunals to issue anti-process or anti-suit injunctions. These measures classified as precautionary measures aim to protect the jurisdictional monopoly granted by the parties to the arbitral tribunal to address the risk of two parallel proceedings and two contradictory decisions being issued. However, despite appearing to be a useful remedy in arbitral material, it has certain questions that diminish its application.In this article, the authors analyze such measures to address the questioning that limit its application to verify their efficiency and validity. It also assesses its requirements under international arbitration practice to corroborate whether they conform to the Peruvian regulatory framework.

At present we observe a vigorous developmental of the cognitive science like a multidisciplinary field that involve several disciplines, such as cognitive psychology, artificial intelligence, linguistics, philosophy, neuroscience, and cognitive anthropology, in order to study the cognition. The study of cognition and mind has been made from a point of view of the speculative philosophy, or from perspective of the philosophy of mind, or from a point of view scientific. The hypothetical and/or theoretical proposals offered from those studies, are discussed and are submitted to experimental analysis, for the purpose to test their scientific validity. Thus, the cognitive science set the essential properties of mind and cognition, such as the representational nature of mind, the causal relation between the cognitive representation and the behavior, the symbolic nature of information mentally ...

Objective: This study analyzes practical, didactic, and evaluative experiences in the context of university professional practice, drawing on the narratives of 47 students (from initial, intermediate, and final internships) and 9 tutor-teachers from two campuses of a state university in southern Chile. Method: Data were collected through discussion groups guided by a thematically validated script and analyzed using structural analysis, applying a parallel structure in the form of binary discourse. Results: The findings show that tutor-teacher supervision promotes dialogic learning and that the emotional dimension is a central component of student–teacher interactions. In addition, the portfolio of evidence emerges as the most widely used didactic and evaluative resource in the training process. Discussion: Student narratives reveal tensions related to the outdated knowledge of some tut...

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...

In this work, the design of symmetric OTAs with low transconductance value (nA/V order) and their application in low frequency and low power is presented. For this aim, the series-parallel (S-P) mirrors was used, which divided the differential pair transconductance. With this technique, a 1 nA/V transconductor is reached. Techniques for extend the linear range (hundreds milivolts) of the differential pair will presented too. The Advanced Compact MOSFET Model ACM was used in the design process. These symmetric OTAs designed will be used in active filters with low central frequency, for biomedical applications (EEG signals). The capacitors of this filters are in the picofaradads order, and are off chip. These OTAs and filters were designed in 0.8 um standard technology. These techniques that we will present will be validated through simulation

Low Density Parity Check codes presents itself as the dominant FEC code in terms of performance, having the nearest performance to the Shannon limit and proving its usefulness in the increasing range of applications and standards that already used it. Low power devices are not except of this rapid development, where it emerges the necessity of decoders of low power without totally sacrificing performance or resource usage. The present work details the devolopment of a LDPC decoder compliant with the DVB-S2 standard for digital television, motivated for its already established use in uplink and downlink satellite applications and its great performance at large code lengths. This research presents the study of the min-sum algorithm and the design of the elements that conform the core decoder, including both functional units (variable and check nodes), memory blocks and routing network. In ...

Academic self-efficacy is a powerful predictor of academic success, yet there are several factors that predispose it. Because of this, an explanatory model is proposed using the self-regulation of academic activities, positive affection, and personality. Hierarchical multiple linear regression was used to support the predictive proposal of the model. The Specific Perceived Self-Efficacy Scale of Academic Situations, The Scale of Positive and Negative Experience, Subscale Self-Regulation of Activities of the Academic Procrastination Scale, and Mini International Personality Item Pool (MINI-IPIP) were used. High correlations were obtained in the self-regulation of activities, positive affection, and personality (extraversion, concientousness and openness to experience) to academic self-efficacy. The final predictive model explained 30.1% of the total variance of academic self-efficacy. In ...
