Avances en tecnologías de drones militares

Paul Balladares — 2024-12-27

In recent years, military drone technologies have undergone accelerated development driven by the need to improve efficiency and precision in defense and security operations. This paper describes the most recent advances in technologies that contribute to the better performance of drones in the execution of their military tasks, addressing the participation of artificial intelligence systems, autonomy capabilities, and improvements in sensors for drones in tactical and strategic missions. Technological advances have driven a significant increase in operational capability and reduced risks for military personnel, thanks to drone technologies with greater autonomy and accuracy. Advances in this area are redefining the landscape of modern military activity and pose new challenges regarding ethical regulations and autonomous arms control, suggesting the need for a robust and up-to-date international regulatory framework.

Diagnosis of low insulation fault in the starting transient of squirrel cage rotor induction motors using wavelet analysis

Alfredo Alejandro Marot Guevara — 2024-12-28

The objective of this work was to diagnose faults in squirrel-cage induction motors during the startup transient, by analyzing the stator current signal. To achieve this, low- and medium-voltage motors were modeled in Simulink using MATLAB. Previously, the fault due to low insulation was diagnosed through a static test. It was demonstrated that, during the startup transient, the low insulation fault manifests through a Daubechies wavelet analysis at level 8 of the current signal. The fault was identified in the detail levels 1, 2, 5, 6, 7, and 8, for both low-voltage and medium-voltage motors.

Strategies to optimize energy consumption in smart buildings

Angel Lezama — 2024-12-28

This article analyzes emerging technologies and management approaches to reduce energy consumption in smart buildings, focusing on Latin America. Strategies based on the Internet of Things (IoT), automation systems, and predictive energy models are examined, with implementation examples in different regional urban contexts. In addition, the environmental, social, and economic benefits derived from these practices are discussed. The energy analysis, for the specific cases studied, shows that the sustainable approach combines bioclimatic conditions to the region with the general use of various technological approaches.

Gravitational waves: echoes of the universe in motion

Adrian David Hauser — 2024-12-31

This paper presents a scientific essay on gravitational waves and their participation in the understanding of fundamental phenomena of the universe. Their discovery, based on the predictions of Einstein's theory of general relativity, and the impact they have had on modern astronomy are analyzed. In addition, the technological advances that have allowed its detection, such as the LIGO and Virgo interferometers, are addressed, highlighting its crucial role in the development of a new era in the observation of the cosmos. This essay also reflects on the scientific, technological, and philosophical implications of gravitational waves, as well as their potential to transform our knowledge about black holes, cosmic collisions, and the structure of space-time. Finally, it explores how this research opens the door to deeper questions about the origin and evolution of the universe.
