Tailored Chip Breaker Development for Polycrystalline Diamond Inserts: FEM-based Design and Validation
A Bibliometric Overview of the International Journal of Interactive Multimedia and Artificial Intelligence
The International Journal of Interactive Multimedia and Artificial Intelligence (IJIMAI) published its first issue ten years ago. Currently, IJIMAI is indexed in the important database Emerging Sources Citation Index. This paper aims to identify, through a mapping of science, those most relevant aspects of the structure of publications made during the first 10 years of IJIMAI. Using VOSviewer software, the structural maps of the IJIMAI publications are analysed according to techniques such as bibliographic coupling, co-citations and cooccurrence of keywords. In addition, the evolution of the publications, citations and an analysis of the most cited papers of the journal are presented. The results show that IJIMAI has experienced a remarkable growth of both publications and citations in the last five years. We also observe that IJIMAI does not only capture the attention of the Spanish scientific community, but also of emerging countries such as India and Iran and emerging Latin American countries such as Colombia. With a such increasing behaviour, it is expected in the coming years that IJIMAI will position itself among the best journals with similar scientific scope
Revisión de la literatura ortodóncica de 1990
La revisión de la literatura ortodóncica del año 1990 se divide, al igual que el año pasado, en ocho bloques: Ciencias básicas, aspectos prácticos de la atención en la consulta, diagnóstico, materiales, articulación temporomandibular, aparatología, terapéutica, retención, recidiva y yatrogenia. Dentro de cada bloque el lector se encontrará con más apartados y subapartados que muestran el amplio abanico de temas que recoge la literatura. Debido al creciente interés de la ortodoncia de adultos y de la cirugía ortognática hemos creído conveniente añadir el lntemational Joumal of Adult Orthodontícs and Orthognathic Surgery a las publicaciones revisadas habitualmente

Los vientos catabáticos y su impacto en el régimen estable nocturno durante el verano de 2017 en el bosque de La Herrería (Madrid)
Ponencia presentada en: XXXV Jornadas Científicas de la AME y el XIX Encuentro Hispano Luso de Meteorología celebrado en León, del 5 al 7 de marzo de 2018.En este estudio analizamos las características de los vientos catabáticos y sus consecuencias en la capa límite estable nocturna durante el verano de 2017 en la torre meteorológica de 10 m de la Red GuMNet de La Herrería (San Lorenzo de El Escorial, Madrid). Dentro del conjunto de todos los eventos catabáticos encontramos casos muy diferentes entre sí dependiendo del máximo de viento (VM) alcanzado tras su establecimiento: catabáticos débiles (VM 3.5 m/s). Los primeros dan lugar a una inversión térmica superficial asociada a un régimen estable, con turbulencia débil, favoreciendo el desacoplamiento entre niveles verticales. Por otro lado, los catabáticos intensos se intensifican progresivamente tras su establecimiento. Estos originan la ruptura de la inversión térmica superficial debido a un aumento de la turbulencia de origen mecánico, y el máximo de turbulencia medido durante el evento catabático es superior al que se produce en las horas centrales del día. El impacto en la turbulencia es cuantificado mediante diversos parámetros de microescala.Este trabajo ha sido financiado por el Proyecto ATMOUNT-II [Ref.

Carbon dioxide fluxes across the Sierra de Guadarrama, Spain
Understanding the spatial and temporal variation in soil respiration within small geographic areas is essential to accurately assess the carbon budget on a global scale. In this study, we investigated the factors controlling soil respiration in an altitudinal gradient in a southern Mediterranean mixed pine–oak forest ecosystem in the north face of the Sierra de Guadarrama in Spain. Soil respiration was measured in five Pinus sylvestris L. plots over a period of 1 year by means of a closed dynamic system (LI-COR 6400). Soil temperature and water content were measured at the same time as soil respiration. Other soil physico-chemical and microbiological properties were measured during the study. Measured soil respiration ranged from 6.8 to 1.4 lmol m-2 s-1, showing the highest values at plots situated at higher elevation. Q10 values ranged between 1.30 and 2.04, while R10 values ranged between 2.0 and 3.6. The results indicate that the seasonal variation of soil respiration was mainly controlled by soil temperature and moisture. Among sites, soil carbon and nitrogen stocks regulate soil respiration in addition to soil temperature and moisture. Our results suggest that application of standard models to estimate soil respiration for small geographic areas may not be adequate unless other factors are considered in addition to soil temperature
Discretization of the Region of Interest
[EN]The meccano method was recently introduced to construct simultaneously tetrahedral meshes and volumetric parameterizations of solids. The method requires the information of the solid geometry that is defined by its surface, a meccano, i.e., an outline of the solid defined by connected polyhedral pieces, and a tolerance that fixes the desired approximation of the solid surface. The method builds an adaptive tetrahedral mesh of the solid (physical domain) as a deformation of an appropriate tetrahedral mesh of the meccano (parametric domain). The main stages of the procedure involve an admissible mapping between the meccano and the solid boundaries, the nested Kossaczký’s refinement, and our simultaneous untangling and smoothing algorithm. In this chapter, we focus on the application of the method to build tetrahedral meshes over complex terrain, that is interesting for simulation of environmental processes. A digital elevation map of the terrain, the height of the domain, and the required orography approximation are given as input data. In addition, the geometry of buildings or stacks can be considered. In these applications, we have considered a simple cuboid as meccano.Ministerio de Economía y Competitividad, Gobierno de España; Fondos FEDER; Departamento de Educación, Junta de Castilla y León; CONACYT-SENER, Fondo Sectorial CONACYT SENER HIDROCARBUROS
