Deep Convolutional Neural Network for HEp-2 fluorescence intensity classification
2019
Indirect ImmunoFluorescence (IIF) assays are recommended as the gold standard method for detection of antinuclear antibodies (ANAs), which are of considerable importance in the diagnosis of autoimmune diseases. Fluorescence intensity analysis is very often complex, and depending on the capabilities of the operator, the association with incorrect classes is statistically easy. In this paper, we present a Convolutional Neural Network (CNN) system to classify positive/negative fluorescence intensity of HEp-2 IIF images, which is important for autoimmune diseases diagnosis. The method uses the best known pre-trained CNNs to extract features and a support vector machine (SVM) classifier for the …
How Do We Know If There’s a Message?
2010
As we have seen, radio waves can be excellent candidates for interplanetary communication, due to the fact that our galaxy is transparent to them. The problem lies in properly identifying the origin – artificial or natural – of an arriving signal. When we tune a radio receiver and we turn the antenna toward the cosmos, we gather hundreds of different signals. Even some of the natural signals are quite suggestive, and one can be tempted to consider them emissions from other civilizations.
Numerical Simulation of Thermal Effects in Coupled Optoelectronic Device-circuit Systems
2008
The control of thermal effects becomes more and more important in modern semiconductor circuits like in the simplified CMOS transceiver representation described by U. Feldmann in the above article Numerical simulation of multiscale models for radio frequency circuits in the time domain. The standard approach for modeling integrated circuits is to replace the semiconductor devices by equivalent circuits consisting of basic elements and resulting in so-called compact models. Parasitic thermal effects, however, require a very large number of basic elements and a careful adjustment of the resulting large number of parameters in order to achieve the needed accuracy.
REFLECTIONS ON MANAGERIAL COMMUNICATION
2012
Modern management has given an extremely important place to managerial communication. It considers communication as a vital component of the managerial system of all organizations. A successful manager is the one that can communicate with the persons that he or she is leading, and the performance of an organization can be conditioned by the manner in which managers communicate. The identification of employees with the organizational goals, their channeling of efforts for the common objectives, the ability of the manager to assess the results of his or her decisions can be accomplished only by using the resources of managerial communication. A laconic, delayed or confused managerial communic…
Instalaciones de producción de vino y aceite en el litoral castellonense
2012
La zona costera de Castellón, dividida en la antigüedad entre los territorios de Dertosa y Saguntum , está ocupada por un poblamiento rural diseminado. En ella se conocen más de 180 yacimientos de diferentes tipos y categorías, de los que tan sólo doce ofrecen indicios o evidencias de instalaciones para la producción de vino o aceite. En este trabajo presentamos una síntesis sobre los restos arqueológicos conocidos que pueden relacionarse con este tipo de actividades. The coastal area of Castellón, in ancient times divided between the territories of Derto - sa and Saguntum , is occupied by a rural settlement spread. In this area more than 180 sites are known, of different types and categori…
Análisis de los factores determinantes de la lealtad hacia los servicios bancarios online
2011
ResumenEl rápido crecimiento de la banca online refleja las ventajas que ésta ofrece respecto a las sucursales convencionales. No obstante, son muchos los consumidores que todavía utilizan los servicios bancarios online de forma esporádica, fundamentalmente para la comprobación de saldos, evitando realizar transacciones con un mayor nivel de riesgo. El objetivo de este estudio es analizar los factores determinantes de la lealtad hacia los servicios bancarios online, a través de un modelo integrador de la influencia del riesgo percibido y la confianza en las webs bancarias con el marco conceptual de la Teoría del Comportamiento Planificado (TCP). La configuración del riesgo percibido se ha p…
Cardiopulmonary Exercise Testing in Patients with Chronic Heart Failure: Prognostic Comparison from Peak VO2 and VE/VCO2 Slope
2010
Background: Cardiopulmonary exercise testing with ventilatory expired gas analysis (CPET) has proven to be a valuable tool for assessing patients with chronic heart failure (CHF). The maximal oxygen uptake (peak V02) is used in risk stratification of patients with CHF. The minute ventilation-carbon dioxide production relationship (VE/VCO2 slope) has recently demonstrated prognostic significance in patients with CHF. Methods: Between January 2006 and December 2007 we performed CPET in 184 pts (146 M, 38 F, mean age 59.8 ± 12.9 years), with stable CHF (96 coronary artery disease, 88 dilated cardiomyopathy), in NYHA functional class II (n.107) - III (n.77), with left ventricular ejection frac…
La calidad percibida de los servicios deportivos : diferencias según instalación, género, edad y tipo de usuario en servicios náuticos
2008
En el ámbito de la gestión deportiva, la calidad de los servicios deportivos y la satisfacción de los usuarios es un área de gran desarrollo. Este trabajo pretende determinar el grado de calidad percibida en unos servicios deportivos de carácter público como son unas escuelas de actividades náuticas. Para ello se analizaron 2375 usuarios de estas escuelas que contestaron un cuestionario sobre calidad de servicio percibida y satisfacción con el servicio recibido. La escala de calidad percibida utilizada determinó diez dimensiones de calidad: las clases, el tiempo libre, el entorno náutico, los horarios, la comida, el material náutico, la comida complementaria, la conserjería, la limpieza y l…
Consumer expectations and perceptions of meat and meat product quality
2011
This paper presents the determinants of perceived quality viewed by different authors. Then, it sets the factors of quality from purchase to consumption and some mechanisms of change over time. After this general presentation, the distinctive features of food and the particular place of meat and meat products among foods are underlined. Important credence and experience attributes as well as quality cues for meat and meat products are then presented through results from previous works. Finally, the advantages but also the limitations of present methodologies used in quality research are presented and some orientations for future research are suggested.
Perceived-Value-driven Optimization of Energy Consumption in Smart Homes
2020
Residential energy consumption has been rising rapidly during the last few decades. Several research efforts have been made to reduce residential energy consumption, including demand response and smart residential environments. However, recent research has shown that these approaches may actually cause an increase in the overall consumption, due to the complex psychological processes that occur when human users interact with these energy management systems. In this article, using an interdisciplinary approach, we introduce a perceived-value driven framework for energy management in smart residential environments that considers how users perceive values of different appliances and how the us…
