(Des)orden y signos políticos dominantes del expresidente colombiano Álvaro Uribe Vélez

Abstract: El trabajo realiza un análisis del campo discursivo del expresidente colombiano Álvaro Uribe Vélez (AUV). Con base en una metodología cualitativa de análisis de discurso, centrado en la construcción de unidades de interpretación hermenéutica (Cf. Kohler, 1993), se busca identificar la experiencia de orden de AUV. La pregunta de investigación se refiere a la identificación de los contenidos sígnicos connotados en la representación política de la realidad y su incidencia en la constitución del campo de la vida p… Show more

“…System Definition. Let consider a MIMO LTI system which its states and output matrices contain time varying uncertainties and under input attck as following: 𝑥(𝑡) = (𝐴 + Δ𝐴(𝑡))𝑥(𝑡) + 𝐵(𝑢(𝑡) + 𝑎 𝑢 (𝑡)) 𝑦(𝑡) = (𝐶 + Δ𝐶(𝑡))𝑥(𝑡) + 𝐷𝑤 (1) where 𝑥 ∈ ℝ 𝑛 , 𝑦 ∈ ℝ 𝑞 , 𝑢 ∈ ℝ 𝑚 , 𝑤 ∈ ℝ 𝑝 are the states, output, input, and noise disturbance vectors respectively. 𝐴 ∈ ℝ 𝑛×𝑛 is the open-loop matrix of the system; 𝐵 ∈ ℝ 𝑛×𝑚 is the control matix; 𝐶 ∈ ℝ 𝑞×𝑛 is the output matrix ; 𝐷 ∈ ℝ 𝑞×𝑝 is known with appropriare dimension.…”

“…Cyber-Physical Systems (CPSs) is modern autonomous engineering systems embedding physical components, communications, and computational capabilities/control logic [1]. Recent advances in modern engineering i.e., power grids [2] lead many researches consider to various problems in this field such as stability analysis [3], fault detection [4], and security problems [5].…”
