Robust Traffic Sign Detection by means of Vision and V2I Communications

14th International IEEE Annual Conference on Intelligent Transportation Systems - ITSC, , 05/10/2011-07/10/2011, Washington DC, Estados UnidosThis paper presents a complete traffic sign recognition system, including the steps of detection, recognition and tracking. The Hough transform is used as detection method from the information extracted in contour images, while the proposed recognition system is based on Support Vector Machines (SVM), and is able to recognize up to one hundred of the main road signs. Besides a novel solution to the problem of discarding detected signs that do not pertain to the host road is proposed, for that purpose vehicle-to-infrastructure (V2I) communication and stereo information is used. This paper presents plenty of tests in real driving conditions, both day and night, in which a high success rate and low number of false negatives and true positives were obtained, and an average runtime of 35 ms, allowing real-time performance

Nested shallow geothermal systems

The long-term sustainability of shallow geothermal systems in dense urbanized areas can be potentially compromised by the existence of thermal interfaces. Thermal interferences between systems have to be avoided to prevent the loss of system performance. Nevertheless, in this work we provide evidence of a positive feedback from thermal interferences in certain controlled situations. Two real groundwater heat pump systems were investigated using real exploitation data sets to estimate the thermal energy demand bias and, by extrapolation, to assess the nature of thermal interferences between the systems. To do that, thermal interferences were modelled by means of a calibrated and validated 3D city-scale numerical model reproducing groundwater flow and heat transport. Results obtained showed a 39% (522 MWh·yr−1) energy imbalance towards cooling for one of the systems, which generated a hot thermal plume towards the downgradient and second system investigated. The nested system in the hot thermal plume only used groundwater for heating, thus establishing a positive symbiotic relationship between them. Considering the energy balance of both systems together, a reduced 9% imbalance was found, hence ensuring the long-term sustainability and renewability of the shallow geothermal resource exploited. The nested geothermal systems described illustrate the possibilities of a new management strategy in shallow geothermal energy governanc

Routing Topologies of Wireless Sensor Networks for Health Monitoring of a Cultural Heritage Site

This paper provides a performance evaluation of tree and mesh routing topologies of wireless sensor networks (WSNs) in a cultural heritage site. The historical site selected was San Juan Bautista church in Talamanca de Jarama (Madrid, Spain). We report the preliminary analysis required to study the effects of heating in this historical location using WSNs to monitor the temperature and humidity conditions during periods of weeks. To test which routing topology was better for this kind of application, the WSNs were first deployed on the upper floor of the CAEND institute in Arganda del Rey simulating the church deployment, but in the former scenario there was no direct line of sight between the WSN elements. Two parameters were selected to evaluate the performance of the routing topologies of WSNs: the percentage of received messages and the lifetime of the wireless sensor network. To analyze in more detail which topology gave the best performance, other communication parameters were also measured. The tree topology used was the collection tree protocol and the mesh topology was the XMESH provided by MEMSIC (Andover, MA, USA). For the scenarios presented in this paper, it can be concluded that the tree topology lost fewer messages than the mesh topology.The Spanish Ministry of Economy and Competitiveness supported this research under grant numbers BIA2009-14395-C04-01 and TEC2012-38402-C04-03.

Negative impact of chronic obstructive pulmonary disease on the health-related quality of life of patients. Results of the EPIDEPOC study

BACKGROUND: COPD is currently the fourth cause of morbidity and mortality in the developed world. Patients with COPD experience a progressive deterioration and disability, which lead to a worsening in their health-related quality of life (HRQoL). The aim of this work is to assess the Health-Related Quality of Life (HRQoL) of patients with stable COPD followed in primary care and to identify possible predictors of disease. METHODS: It is a multicenter, epidemiological, observational, descriptive study. Subjects of both sexes, older than 40 years and diagnosed of COPD at least 12 months before starting the study were included. Sociodemographic data, severity of disease, comorbidity, and use of health resources in the previous 12 months were collected. All patients were administered a generic quality-of-life questionnaire, the SF-12, that enables to calculate two scores, the physical (PCS-12) and the mental (MCS-12) component summary scores. RESULTS: 10,711 patients were evaluated (75.6% men, 24.4% women), with a mean age of 67.1 years (SD 9.66). The mean value of FEV(1 )was 35.9 ± 10.0%. Mean PCS-12 and MCS-12 scores were 36.0 ± 9.9 and 48.3 ± 10.9, respectively. Compared to the reference population, patients with COPD had a reduction of PCS-12, even in mild stages of the disease. The correlation with FEV(1 )was higher for PCS-12 (r = 0.38) than for MCS-12 (r = 0.12). Predictors for both HRQoL components were sex, FEV(1), use of oxygen therapy, and number of visits to emergency rooms and hospital admissions. Other independent predictors of PCS-12 were age, body mass index and educational level. CONCLUSION: Patients with stable COPD show a reduction of their HRQoL, even in mild stages of the disease. The factors determining the HRQoL include sex, FEV(1), use of oxygen therapy, and number of visits to emergency rooms and hospital admissions

Salicylic acid and Bacillus subtilis as control of early blight (Alternaria solani) in tomato plants (Solanum lycopersicum)

Alternaria solani is the causal agent of early blight disease in tomatoes (Solanum lycopersicum) and every year is responsible for significant economic losses suffered worldwide by the producers of this crop. Since salicylic acid and Bacillus subtilis are resistance-inducing agents in plants, they were evaluated in order to know their effect on the infection caused by early blight in the tomato crop. Plants of 75 days old were transplanted in furrows 8 m wide by 43.2 m long, the exogenous application of treatments were made, growth variables (plant height and stem diameter), yield (total fruits) and damage in tomato plants were evaluated. The results show significant statistical differences between treatments compared with the control (P≤0.000). B. subtilis applied to the root and salicylic acid applied to the foliage, reduced the severity of A. solani in tomato plants, and caused a significant increment in the crop growth and yield. The use of resistance inducers can represent an alternative of sustainable production and efficient control against pathogens, aimed at reducing the use of agrochemicals and production costs.Alternaria solani is the causal agent of early blight disease in tomatoes (Solanum lycopersicum) and every year is responsible for significant economic losses suffered worldwide by the producers of this crop.

Debido a que el ácido salicílico y Bacillus subtilis, son agentes inductores de resistencia en las plantas, estos fueron evaluados con la finalidad de conocer su efecto en la infección causada por el tizón temprano en el cultivo de tomate. Plantas de 75 días de edad se trasplantaron en surcos de 8 m de ancho por 43,2 m de largo, se realizó la aplicación exógena de los tratamientos, se evaluaron variables de crecimiento (altura de la planta y diámetro del tallo), rendimiento (frutos totales) y daño en plantas de tomate. Los resultados muestran que existen diferencias estadísticas significativas entre los tratamientos comparados con el testigo (P≤0,000). B. subtilis aplicado a la raíz y ácido salicílico aplicado al follaje, redujo la severidad de A. solani en plantas de tomate, al mismo tiempo que causó un incremento significativo en el crecimiento y rendimiento del cultivo. La utilización de inductores de resistencia puede representar una alternativa de producción sustentable y eficiente para el control de patógenos, a fin de reducir el uso de agroquímicos y los costos de producción.

Biometric database acquisition close to “Real World” conditions

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-12397-9_16Revised Selected Papers of Second COST 2102 International Training School, Dublin, Ireland, March 23-27, 2009In this paper we present an autonomous biometric device developed in the framework of a national project. This system is able to capture speech, hand-geometry, online signature and face, and can open a door when the user is positively verified. Nevertheless the main purpose is to acquire a database without supervision (normal databases are collected in the presence of a supervisor that tells you what to do in front of the device, which is an unrealistic situation). This system will permit us to explain the main differences between what we call "real conditions" as opposed to "laboratory conditions".This work has been supported by FEDER and MEC, TEC2006-13141-C03/TCM, and COST-210

A violência nas relações de casais jovens: prevalência, vitimização, perpetração e bidirecionalidade

El objetivo del trabajo fue estudiar las conductas violentas en las relaciones de pareja de jóvenes universitarios, así como la perpetración y la victimización de dichos comportamientos en función del sexo del sujeto que ejerce la violencia. Para esto se realizó un estudio transversal descriptivo sobre una muestra de estudiantes formada por 137 sujetos (101 mujeres y 36 hombres) con edades comprendidas entre los 18 y los 25 años. Los resultados indican que la violencia verbal era el subtipo de agresión más frecuente entre las parejas adolescentes con independencia del sexo. En relación con el tipo de violencia física —tanto ejercida como sufrida— no se hallaron diferencias significativas en función del género. Sin embargo, en el caso de las agresiones sexuales y los comportamientos de control se hallaron diferencias significativas entre mujeres y hombres. En general, el tipo de violencia que se detectó con más frecuencia en este tipo de relación fue de tipo bidireccional, usándose la violencia como método para resolver conflictos en la relación o como consecuencia de comportamientos de control y celos que se mostraron independientemente del sexo de los sujetos. Este tipo de investigaciones son importantes en el propósito de dirigir las políticas de prevención de la violencia y conseguir que se traduzcan en líneas de acción para la reducción o eliminación de esta tipología delictiva. Esto se traduciría en grandes beneficios para las víctimas directas e indirectas, en particular, así como para la sociedad en general.2019-2
