Do we need metamodels AND ontologies for engineering platforms?
2006
In this paper we show how the joint use of metamodeling and ontologies allows to describe domain knowledge for a complex domain. Ontologies are used as stabilized descriptions of a business domain while metamodels allow a fine description of the domain (to be constructed in the initial phases of modeling). We propose to use an ontology for early categorization, i.e., as a "natural" complement of the formal system that is induced by the metamodel.
Reconstruction Improvement in Integral Fourier Holography by Micro-Scanning Method
2015
Although integral holography has many promising advantages in the field of 3D imaging, the resolution of reconstructed holographic image is still limited by the insufficient information captured. To improve the reconstruction quality, an integral Fourier holographic imaging method based on micro-scanning of the micro-lens array is proposed in this paper. The micro-scanning of the micro-lens array can increase the sampling rate in spatial frequency domain and the information of the generated Fourier hologram, which will eventually eliminate the overlapping effect in the reconstructed 3D image. Experiments for different micro-scanning modes are carried out to verify the feasibility of the pro…

Experience in Spain with the first patients in home hemodialysis treated with low-flow dialysate monitors
2021
Resumen La hemodialisis domiciliaria (HDD) con monitores de bajo flujo de liquido de dialisis ha ganado popularidad en los ultimos anos gracias a su sencillez de diseno, portabilidad y capacidad de desplazamiento. No obstante, existen dudas respecto a la adecuacion que este tipo de tecnica ofrece, pues utiliza monitores con bano a flujos bajos y lactato. El objetivo de este estudio fue demostrar los beneficios clinicos de la HDD con el monitor NxStage System One® introducido recientemente en Espana. Presentamos los resultados de un estudio observacional, retrospectivo que incluyo de manera no seleccionada a los primeros pacientes con HDD corta mediante este monitor en 12 centros en Espana. …
Sources of life satisfaction judgments in Latvia
2010
AbstractResearch indicates that life satisfaction judgments may be influenced by many different factors, but there is no clear evidence how these judgments are constructed. The purpose of this study was to examine sources of life satisfaction judgments in Latvia. Respondents (N=605) aged 18 - 70 completed self report measures of life satisfaction (SWLS), satisfaction with life domains, stressful life events, positive and negative affects (PANAS). Regression analysis shows that model including satisfaction with different life domains, positive and negative affects and number of stressful life events measures explains 53% of the variance in the overall life satisfaction. Immediately after com…
RDF-Based Web Information Integration System: A Travel System Use Case
2018
Enterprises are continually faced with the challenge of integrating heterogeneous systems with incompatible interfaces, data structures (Source structured relational databases, semi-structured sources, XML, or unstructured documents: texts), access mode and technologies. When companies adopt SOA (Service Oriented Architecture), that provides an alternative to traditional design of applications by allowing a designer to assemble and compose existing services that implement the functions of a given application domain, they realize that there is a significant risk that Web services only do not solve the problem of compatibility in the data. Our paper gives a solution to these issues by setting…
The Importance of Creative Services Firms in Explaining the Wealth of European Regions
2013
This chapter shows the important impact that a specific set of services, those belonging to the creative industries, have on regional economic development and wealth generation. Creative industries are a set of knowledge-based activities focused on the generation of meaning, contents and aesthetic attributes through the use of creativity, skill and talent, and have the potential to create wealth from trade and intellectual property rights. A key hypothesis in this paper is that creative services firms are a “growth driver” that promotes wealth in the regions where they are located. This is due to the fact that firms in creative industries introduce new ideas that are subsequently transferre…
The impact of the age of vines on soil hydraulic conductivity in vineyards in eastern Spain
2017
Soil infiltration processes manage runoff generation, which in turn affects soil erosion. There is limited information on infiltration rates. In this study, the impact of vine age on soil bulk density (BD) and hydraulic conductivity (Ks) was assessed on a loam soil tilled by chisel plough. Soil sampling was conducted in the inter row area of six vineyards, which differed by the age from planting: 0 (Age 0; just planted), 1, 3, 6, 13, and 25 years (Age 1, Age 3, Age 6, Age 13, and Age 25, respectively). The One Ponding Depth (OPD) approach was applied to ring infiltration data to estimate soil Ks with an α* parameter equal to 0.012 mm-1. Soil bulk density for Age 0 was about 1.5 times greate…
Els cacics rurals valencians i la seva oposició a la guàrdia civil com a guardería rural (1876-1886)
2021
En los diez años que median entre 1876 y 1886 se produjo un amplio debate acerca de los cuerpos de seguridad del Estado. El debate se canalizó a través de la institución Sociedad Económica de Amigos del País de Valencia. A solicitud de la Diputación Provincial, la Guardia Civil se hizo cargo de la custodia de los campos (6-6-1879. Lo que en principio parecía ser un tema de relacionado con la peligrosidad y los robos de cosechas en los campos, acabó siendo un debate sobre qué tipo de cuerpos de seguridad se requerían. Eran años de transición política: se habían celebrado las elecciones constituyentes, se había aprobado la Constitución, se había establecido el Turno de los partido políticos y…
