Retail brand equity: a model based on its dimensions and effects
2013
International audience; Brand equity has been recognized as a key variable in both the academic and professional literature. This article aims to deepen the nature of the retailer equity construct and identify the variables that contribute to its formation, proposing an integrative model based on their dimensions and effects. From an empirical perspective, a survey is carried out with 300 consumers in three retailer categories, in order to analyze the relationships of the model. Due to the formative nature of two of the constructs, the analysis is developed through the partial least squares technique. From the analysis of the results, the importance of store image, perceived store value, an…
Transition to distributed energy generation in Finland: Prospects and barriers
2015
Abstract Small-scale distributed energy generation is expected to play an important role in helping Finland increase its energy self-sufficiency. However, the overall strategy to date for promoting distributed energy remains unclear. It is not yet well understood which factors promote the growth of the distributed energy sector and what barriers need to be removed. In this article we present the results of a questionnaire directed at a panel of 26 experts from the distributed energy value chain and 15 semi-structured interviews with industry and non-industry representatives. We investigated, from a sociotechnical transition perspective, the possibilities and challenges of the transition to …
The Fuzzy Logic Gambit as a Paradigm of Lotfi’s Proposals
2019
Lotfi Zadeh, in discussing the future directions the discipline should have taken, has insisted in highlighting what he called `the Fuzzy Logic Gambit' , whose basic idea is that, when dealing with the solution of a problem through the use of Fuzzy Logic, two different type of precisions exist: ``precision in value'', which is connected to the ability of measuring reality, and ``precision in meaning'', which is what we want to attain when dealing with the real world. While the final goal of Fuzzy Logic is to provide some degree of precision to what is less precise in nature, he has brilliantly suggested that this can be obtained by bartering between precision in value and precision in meani…
Local Equalization and Wide Areas Land Planning in Syracuse
2016
Abstract The implementation process of the Syracuse's Master Plan is characterized by the widespread use of “urban negotiation”. The Municipality has drawn up a protocol aimed at obtaining areas for facilities and public infrastructure in different areas basing on the rule of the transfer of a portion of land in return for the building permission for the remaining part. Since these areas are variously characterized, the negotiation process may not be fair to Municipality or convenient to land owners. Basing on an equalization pattern, this study provides, for each area, the indexes of fairness and convenience, and, more specifically, the difference between the market value of the areas achi…
Estereotipos corporales en las imágenes de los libros de texto de inglés
2017
La educación es el camino para generar conductas positivas en niños y niñas y promover un ambiente social y armónico, así como respeto de los valores éticos y democráticos de nuestra sociedad. Un valor ético y democrático importante es la actitud no discriminante, sin prejuicios y no estereotipada. El objetivo del presente estudio fue analizar la frecuencia de ocurrencia de posibles estereotipos ligados a género, edad, raza y somatotipo presentes en las imágenes de los libros de texto de inglés del tercer ciclo de Primaria del sistema educativo español. Para ello, se ha realizado un estudio descriptivo con 1774 imágenes de 5 colecciones de libros de texto de la asignatura de inglés (Bugs Wo…
One-dimensional nonlinear boundary value problems with variable exponent
2018
In this paper, a class of nonlinear differential boundary value problems with variable exponent is investigated. The existence of at least one non-zero solution is established, without assuming on the nonlinear term any condition either at zero or at infinity. The approach is developed within the framework of the Orlicz-Sobolev spaces with variable exponent and it is based on a local minimum theorem for differentiable functions.
Analyses spectrale et texturale de données haute résolution pour la détection automatique des maladies de la vigne
2019
‘Flavescence dorée’ is a contagious and incurable disease present on the vine leaves. The DAMAV project (Automatic detection of Vine Diseases) aims to develop a solution for automated detection of vine diseases using a micro-drone. The goal is to offer a turnkey solution for wine growers. This tool will allow the search for potential foci, and then more generally any type of detectable vine disease on the foliage. To enable this diagnosis, the foliage is proposed to be studied using a dedicated high-resolution multispectral camera.The objective of this PhD-thesis in the context of DAMAV is to participate in the design and implementation of a Multi-Spectral (MS) image acquisition system and …
A Novel Artificial Mosaic Generation Technique Driven by Local Gradient Analysis
2008
Art often provides valuable hints for technological innovations especially in the field of Image Processing and Computer Graphics. In this paper we present a novel method to generate an artificial mosaic starting from a raster input image. This approach, based on Gradient Vector Flow computation and some smart heuristics, permit us to follow the most important edges maintaining at the same time high frequency details. Several examples and comparisons with other recent mosaic generation approaches show the effectiveness of our technique.
Retrieval of vegetation height in rice fields using polarimetric SAR interferometry with TanDEM-X data
2017
This work presents for the first time a demonstration with satellite data of polarimetric SAR interferometry (PolInSAR) applied to the retrieval of vegetation height in rice fields. Three series of dual-pol interferometric SAR data acquired with large baselines (2–3 km) by the TanDEM-X system during its science phase (April–September 2015) are exploited. A novel inversion algorithm especially suited for rice fields cultivated in flooded soil is proposed and evaluated. The validation is carried out over three test sites located in geographically different areas: Sevilla (SW Spain), Valencia (E Spain), and Ipsala (W Turkey), in which different rice types are present. Results are obtained duri…
The FLuorescence EXplorer Mission Concept-ESA's Earth Explorer 8
2017
In November 2015, the FLuorescence EXplorer (FLEX) was selected as the eighth Earth Explorer mission of the European Space Agency. The tandem mission concept will provide measurements at a spectral and spatial resolution enabling the retrieval and interpretation of the full chlorophyll fluorescence spectrum emitted by the terrestrial vegetation. This paper provides a mission concept overview of the scientific goals, the key objectives related to fluorescence, and the requirements guaranteeing the fitness for purpose of the resulting scientific data set. We present the mission design at the time of selection, i.e., at the end of project phase Phase A/B1, as developed by two independent indus…
