On the Origin of Hobbes’s Conception of Language: The Literary Culture of English Renaissance Humanism
Sergio H. Orozco-Echeverri
Revista de Estudios Sociales , 2012,
Abstract: Hobbes' education in the literary culture of English Renaissance humanism has been overlooked as an important tradition in understanding his position in Early Modern Philosophy. Against the traditional readings of Hobbes' conception of language as a sequel to Medieval nominalism, I will argue that Hobbes' education in the literary culture of Renaissance humanism and his subsequent developments in this tradition would have allowed him to consider philosophical problems raised by new science in an original way and, thus, to introduce his innovative conception of language as the core of his solution to the problem of social and natural orders.
El retraso del reloj del universo: Isaac Newton y la sabiduría de los antiguos
Orozco Echeverri,Sergio Hernán;
Estudios de Filosofía , 2008,
Abstract: for some decades now, it is commonplace in the newton industry to mention once and again newton`s belief in a lost wisdom. nonetheless, the critique and interpretation on this have been limited to stating this belief, without attempting to interpret it. those who have worked most on the problem have limited themselves to showing how that belief was plausible in the intelectual context of the period, pointing out to predecessors and followers of newton who shared that belief. to contrast what has been said, this article explores how, from epistemological and philosophical points of view, the wisdom of the ancients was for newton a legitimate source of information on the world and its purposes, proposing a distinction between time and temporality as complementary levels but as different ones in the search on what has been created.
MODELOS INTERPRETATIVOS DEL CORPUS NEWTONIANO: TRADICIONES HISTORIOGRáFICAS DEL SIGLO XX
Orozco Echeverri,Sergio hernán;
Estudios de Filosofía , 2007,
Abstract: this article tries to establish the scopes and limits of the main interpretations on newton during the 20th century, highlighting on the one hand the textual evidence at disposal, and on the other hand the philosophical and epistemological currents that defines the main features of those interpretations. it will be shown that the rejection of positivism is not sufficient condition for establishing an adequate inter- pretation and, together with the strengthening of the research from newton?s manuscript, it is necessary a wider, and more detailed model that those established by some of the most outstanding scholars like alexandre koyré, i. bernard cohen, betty dobbs, and richard westfall.
Thomas Hobbes y la geometría del estado: anotaciones sobre el estado de naturaleza desdela historia de la ciencia
Orozco Echeverri,Sergio Hernán;
Estudios de Filosofía , 2009,
Abstract: abstract: this article pretends to shed light on hobbes's concept of state of nature, through a reading of his conception of knowledge which makes possible to relate him with the 'new science' or the scientific revolution. in consequence, this article relates hobbes with some problems and traditions of the scientific revolution through a fresh reading of his theory of knowledge, whence the concept of state of nature is redefined in terms of integral cause; this makes possible to argue the need of commonwealth, excluding the anthropological pessimism traditionally attributed to hobbes.
Estudio de la resistencia al desgaste por abrasión - corrosión en recubrimientos depositados mediante proyección térmica
Sergio Echeverri V.,Juliana Bedoya E.,Andres G. Gonzalez H.
Scientia Et Technica , 2007,
Abstract: Se estudió la resistencia al desgaste por abrasión - corrosión de recubrimientos de Ni Al, Ni SiC, Ni -WC y Ni W- Co, depositados mediante proyección térmica sobre sustratos de acero al carbono. El análisis morfológico de los recubrimientos obtenidos se realizó mediante microscopía electrónica de barrido (MEB). Para lograr el desgaste por abrasión-corrosión se suministró H2SO4 (5%Vol) durante el proceso de deslizamiento abrasivo sobre una superficie de SiC con tama o de grano 600, con una velocidad relativa de 550 RPM durante 20 minutos y con una carga de 937,5 gramos aplicada en dirección normal a la superficie del recubrimiento

Abstract: Introduction: Both Diabetes and cardiovascular disease have an important burden of morbidity and death worldwide, being prison’s population in an increased risk for those pathologies. Objective: To assess the cardiovascular disease risk and type 2 diabetes mellitus risk in a population of prisoners in Pereira. Methods: A descriptive study was conducted, selecting the population by convenience. Instruments designed to assess type 2 diabetes and cardiovascular disease risks in ten years were applied. Results: Sixty one males were included in the population, mean age was 48 years. The main cardiovascular risk factors found were: Low vegetables intake (70.5%), abdominal obesity (65.6%), sedentarism (62.3%) and smoking (54.1%); the ten years risk for type 2 diabetes was above low in 66% of the population and the cardiovascular disease risk was between 10% and 20% in 10% of the cases and higher than 40% in 16% of them. Discussion: The high prevalence of modifiable risk factors and measured risk for cardiovascular disease and type 2 diabetes make it necessary to design and apply programs that aim to promote, prevent and diagnose these pathologies that are more extensive and effective than the current ones.
SEGMENTACIóN AUTOMáTICA DE SE ALES NEUROFISIOLóGICAS UTILIZANDO MéTODOS BASADOS EN WAVELETS
ALVARO A. OROZCO,CRISTIAN GUARNIZO,JULIAN D. ECHEVERRI
Scientia Et Technica , 2006,
Abstract: Las se ales bioeléctricas contienen artefactos de una gran variedad de fuentes que traen consigo incertidumbre en las técnicas de procesamiento de se ales y que requieren segmentos estacionarios de la se al para su análisis. En el presente artículo se desarrolla un algoritmo de segmentación basado en wavelets. Las pruebas desarrolladas sobre las bases de datos de pacientes parkinsonianos en las zonas de tálamo y subtálamo dan como resultado que la metodología propuesta permite segmentar de manera apropiada dichas se ales.
ANáLISIS DE REDUCCIóN DE RUIDO EN SE ALES PROVENIENTES DE MICROELECTRODOS DE REGISTRO
ALVARO A. OROZCO,CRISTIAN GUARNIZO,JULIAN D. ECHEVERRI
Scientia Et Technica , 2006,
Abstract: Dentro del tratamiento clásico de las se ales bioeléctricas, diferentes técnicas de preprocesamiento se han utilizado para la eliminación del ruido presente en el registro electrónico mejorando la relación se al a ruido (SNR). Las se ales provenientes de microeléctrodos de registro (MER), son se ales no estacionarias, conformadas por secuencias de disparos provenientes de la actividad neuronal, por un ruido de fondo y por artefactos. Diferentes métodos de análisis de las se ales MER apuntan a eliminar el ruido de fondo y los artefactos para posteriormente ser clasificadas. Este artículo presenta un procedimiento de filtrado basado en wavelets que permite determinar que la actividad neuronal de fondo en las vecindades de un electrodo de registro si aporta información relevante en el proceso.
