New Encodings of Pseudo-Boolean Constraints into CNF
2009
International audience; This paper answers affirmatively the open question of the existence of a polynomial size CNF encoding of pseudo-Boolean (PB) constraints such that generalized arc consistency (GAC) is maintained through unit propagation (UP). All previous encodings of PB constraints either did not allow UP to maintain GAC, or were of exponential size in the worst case. This paper presents an encoding that realizes both of the desired properties. From a theoretical point of view, this narrows the gap between the expressive power of clauses and the one of pseudo-Boolean constraints.
Data service platform for sentinel-2 surface reflectance and value-added products: System use and examples
2016
This technical note presents the first Sentinel-2 data service platform for obtaining atmospherically-corrected images and generating the corresponding value-added products for any land surface on Earth (http://s2.boku.eodc.eu/). Using the European Space Agency’s (ESA) Sen2Cor algorithm, the platform processes ESA’s Level-1C top-of-atmosphere reflectance to atmospherically-corrected bottom-of-atmosphere (BoA) reflectance (Level-2A). The processing runs on-demand, with a global coverage, on the Earth Observation Data Centre (EODC), which is a public-private collaborative IT infrastructure in Vienna (Austria) for archiving, processing, and distributing Earth observation (EO) data (http://www.…
Regional Tourism Development in Romania – Consistency with Policies and Strategies Developed at EU Level
2013
Abstract The national tourism development master plan for the period 2007-2026 focuses on tourism resources of the regions. The regional tourism development strategy should have the opportunities and threats that are found in every county of the region as guide marks. Their identification leads to facilitate the implementation of tourism development strategy, the opportunity maximum use being the revival and growth ramp of tourist activities, preventing threats ensure the proper functioning of the implementation process. In this paper we analyzed a series of indicators of tourist movement in the eight development regions of Romania.
BALANCED VARIABLE ADDITION IN LINEAR MODELS
2018
This paper studies what happens when we move from a short regression to a long regression in a setting where both regressions are subject to misspecification. In this setup, the least-squares estimator in the long regression may have larger inconsistency than the least-squares estimator in the short regression. We provide a simple interpretation for the comparison of the inconsistencies and study under which conditions the additional regressors in the long regression represent a “balanced addition” to the short regression.
The Consistency of Fairness Rules: An Experimental Study
2010
In the last two decades, experimental papers on distributive justice have abounded. Two main results have been replicated. Firstly, there is a multiplicity of fairness rules. Secondly, fairness decisions differ depending on the context. This paper studies individual consistency in the use of fairness rules, as well as the structural factors that lead people to be inconsistent. We use a within-subject design, which allows us to compare individual behavior when the context changes. In line with the literature, we find a multiplicity of fairness rules. However, when we control for consistency, the set of fairness rules is considerably smaller. Only selfishness and strict egalitarianism seem to…
Latest technology and communication consistency in hospitality: a comparison between two Mediterranean countries
2016
AbstractThe goal of this research is to examine customers′ perceptions of the latest technology solutions and marketing communications within the hotel context in two Mediterranean countries – Croatia and Italy. In particular, hotel guests of four- and five-star hotels located in these countries participated in the research. Firstly, guest perceptions of advanced Information and Communication Technology (ICT) and communication consistency are analysed and compared in Croatian and Italian hotels. Secondly, the impact of ICT on communication consistency is tested in both studies. The findings show that the level of customer perceptions of communication consistency is relatively high in both c…
Basic variables in reflection-impulsivity: A training programme to increase reflectivity
1993
We found that reflective children in our study had better academic qualifications than impulsive ones. We worked with a sample of 201 Spanish children in their last year of Primary School. We elaborated and applied an intervention programme to increase reflectivity. The results were excellent and showed consistency and stability, which is very unusual in the context of R-I research. There was no significant difference between boys and girls’ performance on MFF20. The children were 12, 13 and 14 year olds and we found a reflection increase at 13 but not at 14. Contrary to the opinion of Salkind and Nelson on this point concerning MFFT, we believe that MFF20 is adequate for these ages. The Sp…
Quality control for exposure assessment in epidemiological studies
2010
In the framework of an epidemiological study, dosemeters were used for the assessment of radio frequency electromagnetic field exposure. To check the correct dosemeter's performance in terms of consistency of recorded field values over the entire study period, a quality control strategy was developed. In this paper, the concept of quality control and its results is described. From the 20 dosemeters used, 19 were very stable and reproducible, with deviations of a maximum of +/- 1 dB compared with their initial state. One device was found to be faulty and its measurement data had to be excluded from the analysis. As a result of continuous quality control procedures, the confidence in the meas…
Validación de un Cuestionario Multidimensional de Adaptación a la Enfermedad para Pacientes Renales en Diálisis (CMAE-RD) diseñado a partir de un cue…
2020
espanolObjetivos: El objetivo de este trabajo es estudiar las propiedades psicometricas de un cuestionario multidimensional de adaptacion a la enfermedad para pacientes con enfermedad renal en dialisis (CMAE-RD).Metodos: Esta herramienta esta disenada para ser administrada por un profesional de la psicologia en forma de entrevista semiestructurada y fue disenado a partir de un cuestionario previo para pacientes oncohematologicos. Un total de 113 pacientes en hemodialisis fueron entrevistados mediante el CMAE-RD y completaron dos cuestionarios adicionales con propositos de validacion: el HADS (para evaluar ansiedad y depresion) y el CDRISC-2 (para evaluar resiliencia).Resultados: La consiste…
Distraplan: a flexible tool for strategical planning of electrical distribution systems considering distributed generation.
2005
The paper here presented describes and shows DISTRAPLAN (Distribution Strategical Planning), software tool for strategical planning of distribu tion networks at Medium and Low voltage. The software aims at the identification and comparison of network configur ations, optimized in the long term with identification of special features in relation to the main technical-economical-environmental aspects, such as: the number of HV/MV and MV/LV substations, total length of the MV and LV lines and relevant sections, maximum required energy and power, instal lation and losses costs, etc. DISTRAPLAN, in both the main procedures into which it is articulated (strategical planning and evaluation of the …
