In recent years, autonomous driving technologies have become a topic of growing interest due to the promise of safer and more convenient mode of transportation. An essential element in every autonomous driving system is the control algorithm. Classical control schemes, like PID, are not able to manage Multiple Inputs-Multiple Outputs, complex, non-linear systems. A more recent control strategy is Model predictive control (MPC), a modern control method that has shown promising results in systems with complex dynamics. In MPC, a sequence of optimal control inputs are predicted within a short time horizon based on the car dynamics, and soft or hard restriction of the system. In this work, three different nonlinear-MPC (NMPC) controllers were formulated based on a kinematic, and two dynamic models (double-track and single-track). The steering system’s dynamics were additionally identified ...

The improvisation of educational strategies in some university centers during the pandemic highlighted the difficulties of teachers and students to adapt to distance learning. The objective of the study was to know if the teaching methodologies and teaching strategies applied during the pandemic were adequately applied and which methods or educational strategies had a positive impact on university education in Latin America. To this end, articles were reviewed in five databases, using Boolean operators with descriptors related to the topic. The research was conducted based on grounded theory, following the PRISMA methodology, using 31 of 1710 articles for categorical analysis in Atlas ti v.22 software. The results revealed seven emerging categories as determinants in the application of educational strategies and that e-learning was the model with the greatest impact and use in Lati...

Introduction: Poor knowledge on research shown by medical students, and the fact that they must complete their pre-graduate theses in a short time period, lead to doubts with respect to the quality of such research projects. Objective: To determine the quality of theses in order to obtain a medical degree in San Antonio Abad Cusco National University (from 2000 to 2009), and to establish if there is any factor influencing this. Materials and Method: This is a descriptive study using a relational model. The universe was 284 theses. The stratified and random simple included 172 theses. Data was retrospectively and cross-sectionally collected using a valid and reliable instrument, so their quality was assessed (methodology compliance and appropriateness), and we also reviewed the year theses were presented, the number of involved investigators, as well as the design and topics covered.

The research addresses occupational burnout on university teachers, understood as progressive loss of energy, emotional exhaustion, fatigue, irritability, negative attitudes and feelings of dissatisfaction. The purpose of the study was to compare the presence of job burnout on teachers of the School of Education and Electronic Engineering from a Public University of Peru. It was developed according to principles of quantitative approach, transactional non-experimental design, and type of substantive, descriptive-comparative research. The sample was made up of 125 teachers from both faculties to which the Occupational Attendance Scale-EDO was administered. This instrument presented the required validity and reliability. The results obtained through the confirmatory factor model of structural equations, estimated through the asymptotic free distribution method, led to the conclusion that t...

The interactive documentary field has a collaborative dimension since its beginning. This research proposes a model for the analysis of the participation of online communities within interactive documentary, developed on the basis of the previous scientific literature on this topic. Then, analysed case studies have shown the diversity of forms regarding contribution from online communities. On the basis of the different trends observed, five participative designs with different intensities and purposes have been described. Finally, the model has been applied to each design for its evaluation, allowing us to conclude that a significant participation would have to combine several of these designs considering the articulation of participant communities around documentary as well as its contribution to documentary meaning.

In recent years, the evolution plan in the educational system and curriculum has been one of the most important topics in educational circles. This implies that the programs implemented in higher educational system have not been fully achieved for various reasons. One of the most important reasons is "not paying attention to the localization approach in the curriculum". Curriculum planning is one of the interdisciplines that can play an important role in influencing the curriculum process of humanities. However, the lack of a suitable native curriculum model has made it increasingly dependent on foreign sources and plenty of used terms are imported and translated, resulting in little attention to customs, culture, social, economic and political conditions of society. Although our culture and civilization derive from the most complete and highest order of divine teaching, the educational ...

Violence against women is a social problem that not only affects women involved, but also their relatives and their environment. In Peru, it is a topic that is becoming increasingly more visible. In this work, a computational model based on the entropy-weight method, which is an approach from Shannon entropy theory, was used. The entropy-weight method was applied to calculate the weights of the criteria; and then, the departments studied were classified according to the results of a weighted sum. The evaluation criteria were physical violence against women (C1), sexual violence (C2), psychological violence (C3), women who suffered violence and sought help (C4), reported cases of family or sexual violence (C5), gender inequality in the labor force (C6), and victims of femicide (C7). This article presents a map of information on the departments with the highest rate of violence against wom...
