Which fourier components are most informative: General idea and case studies
(2019-05-01)In many practical situations, the information comes not in terms of the original image or signal, but in terms of its Fourier transform. To detect complex features based on this information, it is often necessary to use ... -
A combined computational and experimental study of the adsorption of sulfur containing molecules on molybdenum disulfide nanoparticles
(2018-09-20)Combining density functional theory calculations and temperature programmed desorption (TPD) experiments, the adsorption behavior of various sulfur containing compounds, including C2H5SH, CH3SCH3, tetrahydrothiophene, ... -
Characterization of Impulse Oscillometric Measures of Respiratory Small Airway Function in Children
(2019-03-01)Abstract. Children suffering from asthma are often undiagnosed or misdiagnosed as their symptoms are similar to other respiratory conditions. Spirometry, the "golden" pulmonary function test used for asthma di- agnosis, ... -
Emulador de Turbina de Viento Mediante el Control de Velocidad de un Motor de CD
(2019-09-10)En el presente trabajo se diseña e implementa en tiempo real un controlador de velocidad del motor de corriente directa con excitación separada para emular la operación de una turbina eólica. Se define el modelo de la ... -
Computer-aided classification of small airways dysfunction using impulse oscillometric features: a children-focused review
(2019-10-10)Abstract Background and objective Spirometry, which is the most commonly used technique for asthma diagnosis, is often unsuitable for small children as it requires them to follow exact instructions and perform extreme ... -
Impact of carbon nanotubes in a CrFeMnNiTi alloy proposed as a potential candidate for stainless-steel substitution
(2019-11-01)In the steel industry, the fabrication of sintered products includes the use of graphite as an alloying element and lubricant. This study explores the idea that a sintered alloy with increased properties can be produced ... -
On the Equivalence between Abstract Dialectical Frameworks and Logic Programs
(2019-09-01)Abstract Dialectical Frameworks (ADFs) are argumentation frameworks where each node is associated with an acceptance condition. This allows us to model different types of dependencies as supports and attacks. Previous ... -
Graphite to Graphene: Green Synthesis Using Opuntia ficus-indica
(2019-03-15)Green synthesis promotes partial or total substitution of chemicals that are potentially harmful to the environment with more friendly ones and is also concerned with decreasing energy consumption. In this study, commercial ... -
Target Field of View Prediction Using Artificial Pheromones for People Reidentification
(2019-12-10)People reidentification is a fundamental task in automated video surveillance based on computer vision. Reidentification happens when a person seen in a field of view is the same that has been observed in other fields of ... -
