Extended Recursive Filtering Estimation of Detector Offset Nonuniformity in Infrared Imaging Systems

Abstract: In [1] we presented a recursive filter to estimate the detector offset nonuniformity (NU) noise present in infrared (IR) imaging systems. Such a filter was derived considering an estimation time-window short enough so that the offset NU can be regarded as a constant in noise. Since the offset NU is non-stationary, upon the arrival of new blocks of IR data new estimates of the offset NU have to be computed. In this paper, this recursive filter is extended by adding to the so-called intra-block processing (where offset NU is a constant) an inter-block processing algorithm. The inter-block processing algorithm considers the time varying effect in the offset NU and models it as a discrete-time Gauss-Markov random process. So, the extended filter is designed to compensate continuously for the NU when new blocks of frames arrive. In addition, the theoretical analysis of the estimator provides us expressions for selecting the appropriate parameters required by the algorithm. The ability of the method to compensate for the offset NU is demonstrated by employing several mid-wavelength IR video sequences.

Abandono de niños de tribu indigena del vaupes y la accion del instituto colombiano de bienestar familiar

Abstract: A traves de este articulo se presenta el caso de dos menores de edad en condicion de discapacidad de una comunidad indigena del Vaupes, los cuales a raiz de su discapacidad quedan en completo abandono fisico y emocional por parte de sus familiares, debido principalmente a su condicion y a los imaginarios en salud que maneja la comunidad, los cuales consideran que su situacion es producto de un “mal” y por lo tanto deciden abandonarlos a su suerte para que rapidamente dejen de existir. Asi mismo se abordan las intervenciones que sobre este caso ha hecho el Instituto Colombiano de Bienestar Familiar y sus entidades adscritas para asegurar un adecuado desarrollo de los menores y propender por mejorar su calidad de vida. ABSTRACT Through this article is presented the case of two minors in disability status from an indigenous community of Vaupes, which because of their disability are in complete physical and emotional abandonment of their families, mainly due to their condition and the health imaginaries that manages the community, which consider that their situation is the result of ";;bad";; and therefore decides to leave them to their fortune in order for them to cease their existence. It also discusses the interventions in this case made by the Colombian Family Welfare Institute and related institutions to ensure proper development of children and tend to improve their quality of life. RESUMO Atraves deste artigo apresenta o caso de dois menores no estado de incapacidade do Vaupes comunidade indigena, que devido a sua deficiencia esta no abandono fisico e emocional completa pelas suas familias, principalmente por causa da sua condicao imaginaria e gerencia de saude da comunidade, que consideram que sua situacao e o resultado de ";maus"; e, portanto, decide deixar sua fortuna para rapidamente deixara de existir. Ele tambem discute as intervencoes neste caso fez com que o Bem-Estar Familiar Colombiano Instituto e os organismos relacionados para garantir bom desenvolvimento das criancas e tendem a melhorar a sua qualidade de vida.

Aproximaciones farmacológicas para el tratamiento de la obesidad

Abstract: Obesity is one of the most serious problems of the 21st century and is thought to affect about 300 million people worldwide. According to the Organization for Economic Co-operation and Development (OECD), 18% of the adult population is obese. More alarming is that there is a strong correlation between the development of childhood obesity and its prevalence in adulthood done. Likewise, children who do not have this disease have high chances of staying within normal weight into adulthood. Therefore the present obesity predisposes an early prevalence of this condition in adulthood. The Food and Drug Administration (FDA) has approved so far five drugs against long-term obesity in adults with obesity: lorcaserin, phentermine / topiramate, naltrexone / bupropion and liraglutide in the last two years. A fifth alternative is orlistat, is a drug used short-term efficacy in use up to six months and is solely used to treat childhood obesity. Therefore, new pharmacological alternatives are investigated. It is very important is knowledge of the gut-brain axis and there leptin, which regulates food intake and energy balance in normal weight subjects and is a key hormone in food and body control in both children and adults

Algoritmos para el control de parámetros ventilatorios en equipos mecánicos emergentes

Abstract: En este trabajo se presentan algoritmos para el control de parametros requeridos en equipos de ventilacion mecanica, considerando la emergencia sanitaria ocasionada por COVID-19. Estos algoritmos permiten el control de variables como el pico de presion inspiratoria (PIP), Presion Positiva al Final de la Espiracion (PEEP), Frecuencia Respiratoria (FR), Tiempo Inspiratorio (Ti), Pausa Inspiratoria (Pause ins), Sensibilidad de Disparo (Trigger), Apnea en Modo Espontaneo (Apnea). El conjunto de estos parametros ventilatorios se han implementacion de un equipo de caracter emergente que permite asistir a pacientes con deficiencia respiratoria aguda.
