Análise de estabilidade de Lyapunov em sistemas positivos

Toso, Leonardo F.

Moisés Barbosa de Souza

Abstract: ResumoNa vasta teoria de controle é relevante a análise da estabilidade de um sistema em torno de seus pontos de equilíbrio. Para tanto utilizam-se diversos critérios para estabelecer se o sistema é estável ou não.Neste presente trabalho as definições de estabilidade que serão utilizadas são as de Lyapunov. Para ilustrarmos esta análise,nosso foco neste trabalho é o estudo de estabilidade de sistemas positivos.

The concept of animal welfare has been widely studied and discussed in recent years. This is a science, which seeks an improvement in the quality of life of animals, ensuring that they have the right to their 5 basic freedoms respected. Animal welfare practices seek to have animals express their natural behavior, even when they are in captivity, ensuring their physical and psychological health. Such techniques help in the adaptation of the animal to the environment, especially in captive animals and in breeding. There is a direct relationship between the implementation of animal welfare practices and the ability of them to adapt and have a good quality of life in the environment in which it was inserted. The growing increase in ornamental bird breeding and as pets has revealed the need to study and ensure welfare practices in the rearing of these animals. One of the techniques used to ensure animal welfare is the implementation of different types of environmental enrichments. Environmental enrichment seeks through different techniques and materials to provide more attractive and stimulating environments to animals, allowing interaction between animals and animal-environment, enabling them to enjoy and explore the environment, optimizing the available spaces, providing opportunities for the development of behaviors and natural abilities of the species, reducing the stress caused by space limitation and absence of stimuli. The objective of this work was to relate animal welfare in the implementation of environmental enrichment in two breeding stake of geese and mallards, one for ornamental and domestic purposes, birds being reared as pets. In particular describe the creation, report the implementation of three types of environmental enrichment: food, physical and social, and response of birds after the implementation of this technique of animal welfare promotion. The results of the implementation of food, physical and social environmental enrichment, to improve the well-being of birds, were verified in both breedings, obtaining a positive result. There was an improvement in the behavior of the animals, which is closer to the natural in both groups, attesting to improvement in quality of life and providing physical and psychological well-being to birds.

El concepto de bienestar animal ha sido ampliamente estudiado y discutido en los últimos años. Esta es una ciencia, que busca una mejora en la calidad de vida de los animales, asegurando que tengan el derecho a sus 5 libertades básicas respetadas. Las prácticas de bienestar animal buscan que los animales expresen su comportamiento natural, incluso cuando están en cautiverio, asegurando su salud física y psicológica. Estas técnicas ayudan en la adaptación del animal al medio ambiente, especialmente en animales cautivos y en la cría. Existe una relación directa entre la implementación de las prácticas de bienestar animal y la capacidad de las mismas para adaptarse y tener una buena calidad de vida en el entorno en el que se insertó. El creciente aumento de la cría ornamental de aves y como mascotas ha revelado la necesidad de estudiar y garantizar las prácticas de bienestar en la cría de estos animales. Una de las técnicas utilizadas para garantizar el bienestar animal es la implementación de diferentes tipos de enriquecimiento ambiental. El enriquecimiento ambiental busca a través de diferentes técnicas y materiales proporcionar entornos más atractivos y estimulantes a los animales, permitiendo la interacción entre los animales y el entorno animal, permitiéndoles disfrutar y explorar el medio ambiente, optimizando los espacios disponibles, proporcionando oportunidades para el desarrollo de comportamientos y habilidades naturales de la especie, reduciendo el estrés causado por la limitación del espacio y la ausencia de estímulos. El objetivo de este trabajo era relacionar el bienestar animal en la implementación del enriquecimiento ambiental en dos estacas reproductoras de gansos y ánades reales, una con fines ornamentales y domésticos, siendo las aves criadas como mascotas. En particular, describir la creación, informar de la implementación de tres tipos de enriquecimiento ambiental: alimentos, físicos y sociales, y respuesta de las aves después de la implementación de esta técnica de promoción del bienestar animal. Los resultados de la implementación del enriquecimiento ambiental alimentario, físico y social, para mejorar el bienestar de las aves, fueron verificados en ambas crías, obteniendo un resultado positivo. Hubo una mejora en el comportamiento de los animales, que está más cerca de lo natural en ambos grupos, dando fe de la mejora de la calidad de vida y proporcionando bienestar físico y psicológico a las aves.
