Identification of Granite Varieties from Colour Spectrum Data

The granite processing sector of the northwest of Spain handles many varieties of granite with specific technical and aesthetic properties that command different prices in the natural stone market. Hence, correct granite identification and classification from the outset of processing to the end-product stage optimizes the management and control of stocks of granite slabs and tiles and facilitates the operation of traceability systems. We describe a methodology for automatically identifying granite varieties by processing spectral information captured by a spectrophotometer at various stages of processing using functional machine learning techniques

Creación de la página Web de deportes de la Universidad de Cuenca

El objetivo principal de este proyecto fue incentivar la práctica del deporte y la buena alimentación en la comunidad universitaria. La metodología utilizada fue una investigación tanto cualitativa como cuantitativa de las distintas páginas web de las universidades de Cuenca las cuáles no daban importancia a ninguno de los dos aspectos antes mencionados. Los instrumentos que se utilizaron dentro de la página fueron: entrevistas, fotografías, videos, calendarios, noticias. Como resultado podemos observar al sitio web en completo funcionamiento con sus distintas pestañas que se vinculan directamente con el deporte y la Universidad, estas son: Cultura Física, Liga Deportiva Universitaria, Medicina Deportiva, Ejercicios y Nutrición, Noticias del Deporte (nacionales e internacionales) y contactos. Cada una de ellas cuenta con distintos elementos y multimedia para que el usuario tenga un mejor entendimiento de la temática tratada. Con esta página los estudiantes y docentes de la Universidad encontrarán las alternativas necesarias para una mayor calidad de vida y la práctica del deporte sin necesidad de ir a un gimnasio o nutricionista.The main objective in this project is to dangle the university community to practice sports and a good diet. We used the qualitative and quantitative investigation in our research looking at the other city universities pages and we discover that none of them cares about these two aspects. The tools that we used in the webpage are: interviews, photographs, videos, calendars, and news. As a result of our work we can watch the site completely working with its different tabs associated directly with the University and sports, these are: Physical Education, University Sports League, Sports Medicine, Nutrition and Exercises, Sports News (national and international) and Contact. Each of them has different elements and media for the user so he will have a better understanding of every subject. With this website the students and teachers of the University will find alternatives to get a better quality of life and sports practice without going to any gym or nutritionist.Licenciado en Ciencias de la Comunicación Social en Periodismo y Comunicación DigitalCuenc

A simple polygon-polygon basis method to compare categorical raster maps

In this paper we present a method for comparing categorical raster maps based on comparing categories at the polygon level. In contrast with the most commonly used pixel-level methods of comparison, the proposed method reduces both possible map registration errors and errors resulting from the uncertainty associated with defining the boundaries of each category. The results are presented visually as a map which shows the degree of fit between the compared maps, and analytically as an overall agreement index varying between 0 and 1 and by a fuzzy kappa index. The methodology is illustrated by two examples: the first compares two synthetic maps which were generated specifically to demonstrate the validity of the method, and the second example analyses the use of the method to detect changes over time in two real land-use maps which were made in different years.

Functional experiment design for the analysis of colour changes in granite using new L∗a∗b∗ functional colour coordinates

AbstractWe propose a functional data approach to evaluating colour changes in stone that is based on applying a functional experiment design to the tristimulus curves resulting from the product of the power spectral distribution of the source, the stone reflectance curve and the matching colour functions of the standard observer.The proposed method was applied to an analysis of colour changes in granite after the application of different desalination treatments. The results were compared with those obtained by the classical analysis of variance applied to the colorimetric coordinates L∗a∗b∗.The granite RGB and XYZ colour coordinate systems were obtained by integrating the respective tristimulus curves. The L∗a∗b∗ coordinates, however, were obtained directly by transforming the XYZ coordinates, as no corresponding tristimulus functions have been proposed to date. With a view to comparing the results for these functional and scalar methods for a uniform colour measurement system, these functions, whose integral coincides with the L∗a∗b∗ values, have been deduced and proposed for the first time.The results obtained demonstrate the usefulness of the additional information supplied by the functional approach. However, this information does not replace that produced by the scalar approach for the scalar coordinates, and so it is recommended to use both approaches. The new tristimulus functions associated with the L∗a∗b∗ coordinates are perfectly interpretable in a way analogous to the coordinates themselves, i.e., as the degree of luminosity (L∗), the green–red relative position (a∗) and the blue–yellow relative position (b∗), except that they are interpreted for each infinitesimal wavelength interval.A brief introduction to the colour measurement problem and to functional statistical techniques is provided for readers coming from different disciplines

New approaches towards the synthesis of 1,2,3,4-tetrahydro isoquinoline-3-phosphonic acid (TicP)

Two new strategies for the efficient synthesis of racemic 1,2,3,4-tetrahydroisoquinoline-3-phosphonic acid (TicP) (±)-2 have been developed. The first strategy involves the electron-transfer reduction of the easily obtained α,β-dehydro phosphonophenylalanine followed by a Pictet–Spengler cyclization. The second strategy involves a radical decarboxylation–phosphorylation reaction on 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (Tic). In both strategies, the highly electrophilic N-acyliminium ion is formed as a key intermediate, and the target compound is obtained in good yield using mild reaction conditions and readily available starting materials, complementing existing methodologies and contributing to the easy accessibility of (±)-2 for further research.This work was supported by Consejo Nacional de Ciencia y Tecnología (CONACYT) through projects 286614 and 256985, and Gobierno de Aragon-FEDER (Grupo Aminoacidos y Peptidos E19-17R; FEDER 2014-2020 “Construyendo Europa desde Aragon”).Peer reviewe

Microneurosurgical anatomy of the basal cisterns: A brief review for cisternostomy

Background: Cisternostomy is a surgical technique thought of and developed as an option for severe brain trauma treatment. It demands a particular knowledge and skill to microsurgically approach basal cisterns and effectively manipulate their contents. To perform this procedure safely, the anatomy and pathophysiology must be clearly understood. Methods: Detailed microscopic dissection and anatomical review were done, after a detailed reading of facts and recent publications about cisternostomy. Cisternal pathways and landmark planning are described and augmented using a new method to show de arachnoid borders. Finally, a brief discussion is written as a synopsis. Results: Cisternostomy requires thorough microscopic knowledge and microsurgical skills. This paper intends to provide information to understand better the anatomy related, thus, easing the learning curve. The technique used to show arachnoid borders, complementing cadaveric and surgical images, was useful for this purpose. Conclusion: To perform this procedure safely, it is mandatory to handle microscopic details of cistern anatomy. Reaching a core cistern is necessary to assure effectiveness. This procedure needs, as well, surgical step-by-step landmark planning and performing. Cisternostomy could be a life-saving procedure and a new powerful tool for severe brain trauma treatment. Evidence is being collected to support its indications
