Computer vision techniques for forest fire perception

This paper presents computer vision techniques for forest fire perception involving measurement of forest fire properties (fire front, flame height, flame inclination angle, fire base width) required for the implementation of advanced forest fire-fighting strategies. The system computes a 3D perception model of the fire and could also be used for visualizing the fire evolution in remote computer systems. The presented system integrates the processing of images from visual and infrared cameras. It applies sensor fusion techniques involving also telemetry sensors, and GPS. The paper also includes some results of forest fire experiments.European Commission EVG1-CT-2001-00043European Commission IST-2001-34304Ministerio de Educación y Ciencia DPI2005-0229

A Robot-Sensor Network Security Architecture for Monitoring Applications

This paper presents SNSR (Sensor Network Security using Robots), a novel, open, and flexible architecture that improves security in static sensor networks by benefiting from robot-sensor network cooperation. In SNSR, the robot performs sensor node authentication and radio-based localization (enabling centralized topology computation and route establishment) and directly interacts with nodes to send them configurations or receive status and anomaly reports without intermediaries. SNSR operation is divided into stages set in a feedback iterative structure, which enables repeating the execution of stages to adapt to changes, respond to attacks, or detect and correct errors. By exploiting the robot capabilities, SNSR provides high security levels and adaptability without requiring complex mechanisms. This paper presents SNSR, analyzes its security against common attacks, and experimentally validates its performance

On the importance of the probabilistic model in identifying the most decisive game in a tournament

Identifying the decisive matches in international football tournaments is of great relevance for a variety of decision makers such as organizers, team coaches and/or media managers. This paper addresses this issue by analyzing the role of the statistical approach used to estimate the outcome of the game on the identification of decisive matches on international tournaments for national football teams. We extend the measure of decisiveness proposed by Geenens (2014) in order to allow to predict or evaluate the decisive matches before, during and after a particular game on the tournament. Using information from the 2014 FIFA World Cup, our results suggest that Poisson and kernel regressions significantly outperform the forecasts of ordered probit models. Moreover, we find that although the identification of the most decisive matches is independent of the model considered, the identification of other key matches is model dependent. We also apply this methodology to identify the favorite teams and to predict the most decisive matches in 2015 Copa America before the start of the competition. Furthermore, we compare our forecast approach with respect to the original measure during the knockout stage

Sucesión y restauración en ambientes semiáridos

Extensas áreas abandonadas del sureste peninsular están experimentando actualmente procesos de sucesión secundaria sobre los que tenemos un conocimiento muy escaso. La sucesión secundaria en ambientes áridos es muy lenta y su resultado incierto, ya que el establecimiento de determinadas especies y comunidades está muy limitado. Los esfuerzos para restaurar zonas abandonadas deben basarse en un conocimiento sólido de la sucesión, empleando especies viables, propias de etapas intermedias, capaces de impulsar la sucesión vegetal

Current overview of S-nitrosoglutathione (GSNO) in higher plants

S-nitrosoglutathione is a nitric oxide-derived molecule, generated by the interaction of nitric oxide (NO) with reduced glutathione (GSH) in a process called S-nitrosylation (Figure 1). The reaction appears to take place either through the formation of N2O3 or the addition of NO to a glutathionyl radical formed during this reaction (Broniowska et al., 2013). GSNO is regarded as an intracellular NO reservoir as well as a vehicle of NO throughout the cell, which enables NO biological activity to expand. GSNO is also considered to be the most abundant low-molecular-mass (LMM) S-nitrosothiol (SNO). This family includes other molecules such as S-nitrosocysteine (CySNO) and S-nitrosocysteinylglycine (GlyCySNO), which have been the subject of less study in the field of plant research. There is another group of SNOs called high-molecular mass (HMM) SNOs which are produced by NO binding to sulfhydryl (-SH) groups present in specific cysteine residues of proteins. Figure 1 shows a simple model of GSNO metabolism and its interactions with other molecules in cells where different reactions including S-nitrosylation, S-transnitrosation, and S-glutathionylation are involved (Hogg, 2002; Martínez-Ruiz and Lamas, 2007). In plants, research has focused on the importance of total SNOs in specific stress situations (Feechan et al., 2005; Chaki et al., 2011a) and on the identification of the potential protein targets of S-nitrosylation as this kind of post-translational modification can alter the function of the affected proteins (Astier et al., 2012). Initial studies in this area exogenously applied GSNO in order to identify the pool of potential protein candidates (Lindermayr et al., 2005). However, less attention has been paid to the abundance, distribution, and modulation of endogenous GSNO under natural and stress conditions. In this article, we will provide a current overview of GSNO in higher plants.

Digitizing the Herbarium of the I.E.S. Padre Luis Coloma of Jerez de la Frontera (Cádiz, SW Spain)

Hoy día las tecnologías avanzan a ritmos insospechados, y el acceso a la información es cada vez más fácil y rápido. Aunque es cierto, que mucha información todavía se encuentra en un formato inaccesible o desconocida para muchos, aunque cada vez son las menos. En esta comunicación vamos a explicar el proceso de digitalización del Herbario del IES Padre Luis Coloma de Jerez de la Frontera que data en sus inicios del año 1875 en adelante. Tras el acuerdo inicial con los propietarios del herbario, procedimos a trazar unas directrices para su correcta indexación y fotografiado. Por tanto, recopilamos la información de uno de los apuntes bibliográficos para confeccionar una base de datos primaria. Esto nos ahorró bastante trabajo pues era una recopilación de todas las etiquetas del herbario en sus inicios. Más adelante procedimos a crear un pequeño script web junto a una base de datos MySQL para ir editando datos y haciendo correcciones sobre la marcha del proceso de fotografiado. En este proceso se obtuvieron 6 fotos, una de pliego completo sin etiqueta, 3 de detalles importantes para su identificación y la propia etiqueta en su parte anterior y posterior. Finalmente recopilamos toda esta información, anotamos irregularidades y creamos una página web donde se pueden ver todas las fotos, e información de las etiquetas, junto a la posible información actualizada procedentes de la base de datos de la Flora Iberica. Además procedimos a la realización de un diseño adaptado a móvil y tablets con lo que cualquier persona desde su computadora o desde su propio móvil o tablet puede consultar la información y visualizar las fotos de los aproximádamente más de mil pliegos que componen este herbario.Technologies grows to unexpected rhythms, and access to information is becoming easier and faster. While it is true that a lot of information is still in an inaccessible format or unknown to many, but is increasingly less. In this paper we will explain the process of digitizing the Herbarium of IES Padre Luis Coloma from Jerez (Cádiz, SW Spain) dated in the beginning of 1875 onwards. After the initial agreement with the owners of the herbarium, we proceeded to draw up guidelines for proper indexing and photographed. Thus, we collect the information from one of the bibliographic notes for making a primary database. This saved us a lot of work as it was a compilation of all the labels of the herbarium at the beginning. Later we proceeded to create a small web script next to a MySQL database to go edit data and make corrections on the fly shooting process. In this process were obtained 6 photos, a complete sheet of unlabeled 3 important details to identify and label their own front and back. Finally we collect all this information, we noted irregularities and create a web page where you can see all the pictures, and information on their labels, along with the possible date information from the database of the Flora Iberica. Furthermore proceeded to carry out a design adapted to mobile and tablets with anyone from your computer or from your own phone or tablet can see information and view pictures of the estimated over a thousand sheets that comprise this herbarium

Evaluating significant effects from alternative seeding systems : a Bayesian approach, with an application to the UEFA Champions League

The paper discusses how to evaluate alternative seeding systems in sports competitions. Prior papers have developed an approach which uses a forecasting model at the level of the individual match and then applies Monte Carlo simulation of the whole tournament to estimate the probabilities associated with various outcomes or combinations of outcomes. This allows, for example, a measure of outcome uncertainty to be attached to each proposed seeding regime. However, this established approach takes no note of the uncertainty surrounding the parameter estimates in the underlying match forecasting model and this precludes testing for statistically significant differences between probabilities or outcome uncertainty measures under alternative regimes. We propose a Bayesian approach which resolves this weakness in standard methodology and illustrate its potential by examining the effect of seeding rule changes implemented in the UEFA Champions League, a major football tournament, in 2015. The reform appears to have increased outcome uncertainty. We identify which clubs and which sorts of clubs were favourably or unfavourably affected by the reform, distinguishing effects on probabilities of progression to different phases of the competition.The fourth author acknowledge financial support from the Spanish Ministry of Education and Science, research project ECO2012-32401

Citizen science projects : an opportunity for education in scientific literacy and sustainability

Since the term citizen science first emerged, projects involving citizens in science have increased in number and have spread to a variety of areas. Thus, citizen science is emerging as a mechanism for involving society and stimulating the population’s interest in science and contributing to their scientific literacy. Furthermore, we must also highlight the inherent contribution of citizen science projects to the attainment of the Sustainable Development Goals (SDGs). This paper reviews some examples of international citizen science projects and details active projects in Spain, from the perspective of both formal and non-formal educatio
