Recent Developments in Smart Healthcare

Medicine is undergoing a sector-wide transformation thanks to the advances in computing and networking technologies. Healthcare is changing from reactive and hospital-centered to preventive and personalized, from disease focused to well-being centered. In essence, the healthcare systems, as well as fundamental medicine research, are becoming smarter. We anticipate significant improvements in areas ranging from molecular genomics and proteomics to decision support for healthcare professionals through big data analytics, to support behavior changes through technology-enabled self-management, and social and motivational support. Furthermore, with smart technologies, healthcare delivery could also be made more efficient, higher quality, and lower cost. In this special issue, we received a total 45 submissions and accepted 19 outstanding papers that roughly span across several interesting topics on smart healthcare, including public health, health information technology (Health IT), and smart medicine

What else does your biometric data reveal? A survey on soft biometrics

International audienceRecent research has explored the possibility of extracting ancillary information from primary biometric traits, viz., face, fingerprints, hand geometry and iris. This ancillary information includes personal attributes such as gender, age, ethnicity, hair color, height, weight, etc. Such attributes are known as soft biometrics and have applications in surveillance and indexing biometric databases. These attributes can be used in a fusion framework to improve the matching accuracy of a primary biometric system (e.g., fusing face with gender information), or can be used to generate qualitative descriptions of an individual (e.g., "young Asian female with dark eyes and brown hair"). The latter is particularly useful in bridging the semantic gap between human and machine descriptions of biometric data. In this paper, we provide an overview of soft biometrics and discuss some of the techniques that have been proposed to extract them from image and video data. We also introduce a taxonomy for organizing and classifying soft biometric attributes, and enumerate the strengths and limitations of these attributes in the context of an operational biometric system. Finally, we discuss open research problems in this field. This survey is intended for researchers and practitioners in the field of biometrics

Solución rápida y automática de parámetros hipocentrales para eventos sísmicos, mediante el empleo de técnicas de aprendizaje de máquina

La generación de alertas tempranas para sismos es de gran utilidad, en particular para la ciudad de Bogotá-Colombia, dada su importancia social y económica para el país. Con base en la información de la estación sismológica de El Rosal, la cual es una estación de banda ancha y tres componentes, localizada muy cerca de la ciudad, perteneciente al Servicio Geológico Colombiano (SGC) se desarrolló un modelo de regresión basado en máquinas de vectores de soporte (SVM), con un kernel polinomial normalizado, usando como datos de entrada algunas características de la porción inicial de la onda P empleadas en trabajos anteriores tales como la amplitud máxima, los coeficientes de regresión lineal de los mismos, los parámetros de ajuste logarítmico de la envolvente y los valores propios de la relación de las tres componentes del sismograma. El modelo fue entrenado y evaluado aplicando correlación cruzada, permitiendo llevar a cabo el cálculo de la magnitud y la localización de un evento sísmico con una longitud de señal de tan solo cinco segundos. Con el modelo propuesto se logró la determinación de la magnitud local con una precisión de 0.19 unidades de magnitud, la distancia epicentral con una precisión de alrededor de 11 kilómetros, la profundidad hipocentral con una precisión de aproximadamente 40 kilómetros y el azimut de llegada con una precisión de 45°. Las precisiones obtenidas en magnitud y distancia epicentral son mejores que las encontradas en trabajos anteriores, donde se emplean gran número de eventos para la determinación del modelo y en los demás parámetros hipocentrales son del mismo orden. Este trabajo de investigación realiza un aporte considerable en la generación de alertas tempranas para sismos, no solamente para el país sino para cualquier otro lugar donde se deseen implementar los modelos aquí propuestos y es un excelente punto de partida para investigaciones futuras.Abstract. Earthquake early warning alerts generation is very useful, especially for the city of Bogotá-Colombia, given the social and economic importance of this city for the country. Based on the information from the seismological station “El Rosal”, which is a broadband and three components station, located very near the city that belongs to the Servicio Geológico Colombiano (SGC) a Support Vector Machine Regression (SVMR) model was developed, using a Normalized Polynomial Kernel, using as input some characteristics of the initial portion of the P wave used in earlier works such as the maximum amplitude, the linear regression coefficients of such amplitudes, the logarithmic adjustment parameters of the envelope of the waveform and the eigenvalues of the relationship between the three seismogram components of each band. The model was trained and evaluated by applying a cross-correlation strategy, allowing to calculate the magnitude and location of a seismic event with only five seconds of signal. With the proposed model it was possible to estimate local magnitude with an accuracy of 0.19 units of magnitude, epicentral distance with an accuracy of about 11 km, the hipocentral depth with a precision of approximately 40 km and the arrival back-azimut with a precision of 45°. Accuracies obtained in magnitude and epicentral distance are better that those found in earlier works, where a large number of events were used for model determination, and the other hipocentral parameters precisions obtained here are of the same order. This research work makes a considerable contribution in the generation of seismic early warning alerts, not only for the country but for any other place where proposed models here can be applied and is a very good starting point for future research.Doctorad
