Posibilidades lignitíferas de la cuenca Neógena de Ademuz (Fosa de Teruel)

La cuenca Terciaria de Ademuz es una cuenca intramontañosa-finialpídica colmatada por sedimentos del Mioceno-Plioceno. Se han distinguido cinco unidades litoestratigráficas en los sedimentos terciarios, de las cuales la Unidad Blanca Inferior presenta cierto interés en cuanto a posibilidades lignitíferas. Corresponde esta Unidad a un ambiente lacustre, en el que se depositan dos tipos de facies: Una travertínica, indicadora de un medio palustre muy somero, con abundante vegetación y condiciones oxidantes, y otra de ambiente tipo charca, que corresponde a un medio con lámina de agua escasa, pero mayor que en el caso anterior, con aguas tranquilas y condiciones reductoras, que son las idóneas para la acumulación de restos vegetales y formación de carbón. Las facies de último tipo predominan en dos zonas telmáticas, situadas al abrigo de islas interiores o en zonas marginales, en ambos casos protegidas de los aportes terrígenos, pero fuera de la zona de deposición de sedimentos exclusivamente lacustres, que se corresponden con las zonas de mayor cantidad de indicios de lignito

¿La celebración de un evento promociona la ciudad como destino turístico entre los deportistas?

The organization of events by the cities have different implications, including that athletes who participate in it can know the city and may have intentions of returning to it as tourists or recommend it. This work aims to analyze the predictors of the future intentions of athletes regarding the host city of the event. A questionnaire was administered to 99 athletes in the 12ª World Championship indoor athletics, held in the city of Valencia. The average age is 25.36 years with 59.6% women. The proposed model was significant. The quality dimensions of tangibles and security, and the overall satisfaction and perceived value were significant, therefore, event managers and those responsible for the area of tourism, should get the quality in these areas to increase the future intentions of the athletes regarding the city.La organización de eventos por parte de las ciudades tiene diferentes implicaciones, entre ellas que los deportistas que participan en él conozcan la urbe y puedan tener intenciones de volver a ella como turistas o recomendarla.

Soft Computing Models for the Development of Commercial Conversational Agents

Proceedings of: 6th International Conference on Soft Computing Models in Industrial and Environmental Applications (SOCO 2011). Salamanca, April 6-8, 2011In this paper we present a proposal for the development of conversational agents that, on the one hand, takes into account the benefits of using standards like VoiceXML, whilst on the other, includes a module with a soft computing model that avoids the effort of manually defining the dialog strategy. This module is trained using a labeled dialog corpus, and selects the next system response considering a classification process based on neural networks that takes into account the dialog history. Thus, system developers only need to define a set of VoiceXML files, each including a system prompt and the associated grammar to recognize the users responses to the prompt. We have applied this technique to develop a conversational agent in VoiceXML that provides railway information in Spanish.Funded by projects CICYT TIN2008-06742-C02-02/TSI, CICYT TEC2008-06732-C02- 02/TEC, CAM CONTEXTS (S2009/TIC-1485), and DPS2008-07029-C02-02.Publicad

On the modification of binarization algorithms to retain grayscale information for handwritten text recognition

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-19390-8_24[EN] The amount of digitized legacy documents has been rising over the last years due mainly to the increasing number of on-line digital libraries publishing this kind of documents. The vast majority of them remain waiting to be transcribed to provide historians and other researchers new ways of indexing, consulting and querying them. However, the performance accuracy of state-of-the-art Handwritten Text Recognition techniques decreases dramatically when they are applied to these historical documents. This is mainly due to the typical paper degradation problems. Therefore, robust pre-processing techniques is an important step for helping further recognition steps. This paper proposes to take existing binarization techniques, in order to retain their advantages, and modify them in such a way that some of the original grayscale information is preserved and be considered by the subsequent recognizer. Results are reported with the publicly available ESPOSALLES database.The research leading to these results has received funding from the European Union’s Seventh Framework Programme FP7/2007-2013) under grant agreement No. 600707 - tranScriptorium and the Spanish MEC under the STraDA project (TIN2012-37475-C02-01).Villegas, M.; Romero Gómez, V.; Sánchez Peiró, JA.

Automation of thermographic 3D modelling through image fusion and image matching techniques

Infrared thermography has proved to be an adequate technique for building inspection, as it can be used to determine energy efficiency and also to detect defects in construction. Geometry and spatial relationships are also very important in building inspection because they make location of thermal defects and measurement of affected surfaces possible. A procedure to fuse automatically generated infrared mosaics and visible images to combine geometric information with thermal data in the same image is described in this paper. Fused images are then used for the automatic generation of a thermographic 3D model of the building through image matching, where apart from having thermographic information available, geometric measurements can be performed. The proposed methodology is suitable for building inspection, where working space and time are usually limited so a reduction on the number and size of instruments is appreciated. Furthermore, automation of the process diminishes the error in results by avoiding operator's influence.The authors would like to give thanks to Conselleria de Economia e Industria (Xunta de Galicia), Ministerio de Economia y Competitividad and CDTI (Gobierno de Espana) for the financial support given; human resources programs (FPU AP2009-1144) and projects (INCITE 10TMT 011CT, INCITE 10REM033E, IDI-20101770).

High performance grid for the metric calibration of thermographic cameras

The metric calibration of thermographic cameras would make possible the acquisition of geometric data if the principles of photogrammetry are followed. Both the distortion effects introduced in the images by the lens and the perspective effect can be corrected if the calibration parameters are known. This paper presents a calibration grid that allows the automatic metric calibration of thermographic cameras. This calibration grid is made of light and easy-to-find materials to guarantee its portability and handling. The calibration parameters obtained with the presented calibration grid are verified and compared with those obtained with a temperature-based calibration grid through the evaluation of the accuracy and repeatability in the modelling of a standard artefact previously certified. © 2012 IOP Publishing Ltd.The authors would like to thank Conselleria de Economia e Industria (Xunta de Galicia) and Ministerio de Ciencia e Innovacion (Gobierno de Espana) for the financial support given: human resource programmes (IPP055-EXP44, FPU AP2009-1144) and projects (INCITE09 304 262 PR, INCITE 10TMT 011CT and BIA2009-08012).
