Real-Time Automatic Object Classification and Tracking using Genetic Programming and NVIDIA R CUDA TM

Genetic Programming (GP) is a widely used methodology for solving various computational problems. GP's problem solving ability is usually hindered by its long execution times. In this thesis, GP is applied toward real-time computer vision. In particular, object classification and tracking using a parallel GP system is discussed. First, a study of suitable GP languages for object classification is presented. Two main GP approaches for visual pattern classification, namely the block-classifiers and the pixel-classifiers, were studied. Results showed that the pixel-classifiers generally performed better. Using these results, a suitable language was selected for the real-time implementation. Synthetic video data was used in the experiments. The goal of the experiments was to evolve a unique classifier for each texture pattern that existed in the video. The experiments revealed that the system was capable of correctly tracking the textures in the video. The performance of the system was on-par with real-time requirements.

The Effect of Dopants on the Microwave Dielectric Properties of Ba (Mg 0.33 Ta 0.67) O3 Ceramics

The effect of dopants with different valencies and ionic radii on the densification, structural ordering, and microwave dielectric properties of Ba(Mg1/3Ta2/3)O3 (BMT) is investigated. It is found that dopants such as Sb2O5, MnO, ZrO2, WO3, and ZnO improve the microwave dielectric properties of BMT. Addition of trivalent dopants is detrimental to the cation ordering and dielectric properties of BMT. A correlation between the microwave dielectric properties of BMT and ionic radii of the dopant has been established. The variation of the dielectric properties of pure and doped BMT at cryogenic temperatures is also discussed.

A Variational Calculation of TE and TM Cutoff Wavenumbers in Circular Eccentric Guides by Conformal Mapping

The cutoff wavenumbers of higher order modes in circular eccentric guides are computed with the variational analysis combined with a conformal mapping. A conformal mapping is applied to the variational formulation, and the variational equation is solved by the finite-element method. Numerical results for TE and TM cutoff wavenumbers are presented for different distances between the centers and ratio of the radii. Comparisons with numerical results found in the literature validate the presented method

The effect of dopants on the microwave dielectric properties of Ba( Mgo.33Ta0.67)03 ceramics

The effect of dopants with different valencies and ionic radii on the densification, structural ordering, and microwave dielectric properties of Ba(Mg1t3Tazt3)O3 (BMT) is investigated. It is found that dopants such as Sb,05, MnO, ZrO,, WO1, and ZnO improve the microwave dielectric properties of BMT. Addition of trivalent dopants is detrimental to the cation ordering and dielectric properties of BMT. A correlation between the microwave dielectric properties of BMT and ionic radii of the dopant has been established. The variation of the dielectric properties of pure and doped BMT at cryogenic temperatures is also discussed

Revisión sistemática : uso de imágenes por difusión en RMN, para predecir sobrevida en pacientes adultos con diagnostico de glioblastoma multiforme

El Glioblastoma multiforme (GBM), es el tumor cerebral más frecuente, con pronóstico grave y baja sensibilidad al tratamiento inicial. El propósito de este estudio fue evaluar si la Difusión en RM (IDRM), es un biomarcador temprano de respuesta tumoral, útil para tomar decisiones tempranas de tratamiento y para obtener información pronostica. Metodología La búsqueda se realizo en las bases de datos EMBASE, CENTRAL, MEDLINE; las bibliografías también fueron revisadas. Los artículos seleccionados fueron estudios observacionales (casos y controles, cohortes, corte transversal), no se encontró ningún ensayo clínico; todos los participante tenían diagnostico histopatológico de GBM, sometidos a resección quirúrgica y/o radio-quimioterapia y seguimiento de respuesta al tratamiento con IDRM por al menos 6 meses. Los datos extraídos de forma independiente fueron tipo de estudio, participantes, intervenciones, seguimiento, desenlaces (sobrevida, progresión/estabilización de la enfermedad, muerte) Resultados Quince estudios cumplieron los criterios de inclusión. Entre las técnicas empleadas de IDRM para evaluar respuesta radiológica al tratamiento, fueron histogramas del coeficiente aparente de difusion ADC (compararon valores inferiores a la media y el percentil 10 de ADC, con los valores superiores); encontrando en términos generales que un ADC bajo es un fuerte predictor de sobrevida y/o progresión del tumor. (Esto fue significativo en 5 estudios); mapas funcionales de difusion (FDM) (midieron el porcentaje de cambio de ADC basal vs pos tratamiento) que mostro ser un fuerte predictor de sobrevida en pacientes con progresión tumoral. DISCUSION Desafortunadamente la calidad de los estudios fue intermedia-baja lo que hace que la aplicabilidad de los estudios sea limitada.

Transformaciones discursivas en el proceso de securitización del narcotráfico. Un análisis de los actos discursivos oficiales de Colombia y Estados Unidos en la Guerra contra las drogas 1986 - 1990

El tema de las drogas suscita un debate entre quienes defienden la prohibición y la represión, y aquellos que defienden alternativas como la legalización y/o regulación y otras más moderadas como la descriminalización y la despenalización. Aunque ambas posturas muestran datos empíricos que las soportan, desde el ámbito discursivo la visión represiva se ha posicionado como la más aceptada en el continente americano, más específicamente, en Latinoamérica. El presente trabajo, hace un estudio de caso del proceso de securitización del narcotráfico entre los presidentes de Estados Unidos y Colombia durante el período 1986-1990. A lo largo del texto, se analizan discursos oficiales de los presidentes de ambos Estados, resaltando las estrategias retóricas y sus transformaciones que legitimaron acciones represivas de tipo político-militar contra las drogas. Al final se apunta a reivindicar el discurso como un instrumento para reproducir creencias sobre fenómenos, en este caso, la creencia de que las drogas son una amenaza existencial a la seguridad política y militar para los Estados.

Excessive work or addiction to work: workaholism in a Colombian company. Pilot study trough application of DUWAS test

This paper examines the workaholism phenomenon in different work situations in Colombian company. Workaholism was defined as the individual’s steady and considerable allocation of time to work, which is not derived from external necessities (1). The research studies about workaholics and workaholism have been increasing a lot in the last years (2). Workaholism is an addiction that actually is affecting a lot of people around the world and has serious consequences in personal life, in the community and also in economy. Some of these researches are directed to explore ways to diagnose when a person is workaholic and when this situation may affect the performanceof the individual in work, daily life activities and especially in psychosocial area. Objective: this pilot study contributes to identify if Colombian workers present the main characteristicsof workaholism and if the job they perform is related to the presence of the characteristics of this addiction. Materials and method: for this pilot study used the Dutch Work Addiction Scale(DUWAS), this test suggests when a person has work addiction, trough the evaluation of two main components working excessively and working compulsively. Results: the study find differences for the two groups: the 67% of the AE group are over the average while only the 33% of the members of the O group are over it. Conclusions: these percentages show that the combinations of the components of workaholism are more evident in the population belonging to the administrative/executive jobs group, giving evidence that workaholism is presented in greater proportion in the population performance management positions.
