Encriptación óptica empleando llaves Weierstrass-Mandelbrot

2013

[EN] This paper presents the generation of encryption keys using the local oscillating properties of the partial sums of Weierstrass-Mandelbrot fractal function. In this way, the security key can be replicated if the parameters used to obtain it are known. Therefore, these parameters can be sent instead of sending the key. This procedure reduces the amount of information to be sent and prevents possible interception of the key. Moreover, the key can not be affected by data loss or pollution. The effectiveness of the Weierstrass-Mandelbrot keys were demonstrated by computer simulation in a 4f optical encryption system and the double random phase encoding technique. These keys allow us to enc…

1985. El Consell Valencià de Cultura. Una ley sin votos en contra ni abstenciones.

2014

El Estatuto de Autonomía de la Comunidad Valenciana, en su artículo 25, recogía como institución de la Generalitat, la creación de un Consell de Cultura: "Una Llei de les Corts Valencianes establirà les funcions, la composició i l’organització del Consell de Cultura, els membres del qual seran elegits per majoria de dos terços de les Corts Valencianes". El proyecto se discutiría entre los grupos parlamentarios, para consensuar un texto duradero y común. Las Cortes Valencianas aprobaran la Llei del Consell Valencià de Cultura el 23 de octubre de 1985. El conseller de Cultura, Educación y Ciencia, Ciprià Císcar, en nombre del Govern Valencia, presentaría el proyecto: "entenent que per formar …

Crisis communication, anticipated food scarcity, and food preferences: Preregistered evidence of the insurance hypothesis

2021

Abstract Whereas large-scale consumption of energy-dense foods contributes to climate change, we investigated whether exposure to climate change-induced food scarcity affects preferences toward these foods. Humans’ current psychological mechanisms have developed in their ancestral evolutionary past to respond to immediate threats and opportunities. Consequently, these mechanisms may not distinguish between cues to actual food scarcity and cues to food scarcity distant in time and space. Drawing on the insurance hypothesis, which postulates that humans should respond to environmental cues to food scarcity through increased energy consumption, we predicted that exposing participants to climat…

The Impact of Trade Liberalisation on Water Use: A Computable General Equilibrium Analysis

2008

Water is scarce in many countries. One instrument to improve the allocation of a scarce resource is (efficient) pricing or taxation. However, water is implicitly traded on international markets, particularly through food and textiles, so that impacts of water taxes cannot be studied in isolation, but require an analysis of international trade implications. We include water as a production factor in a multi-region, multi-sector computable general equilibrium model (GTAP), to assess a series of water tax policies. We find that water taxes reduce water use, and lead to shifts in production, consumption, and international trade patterns. Countries that do not levy water taxes are nonetheless af…

The Economic Impact of Water Taxes: A Computable General Equilibrium Analysis with an International Data Set

Humanismo tecnológico: fundamento para una inteligencia artificial responsable

2019

Los rápidos avances en el campo de la inteligencia artificial (IA) en las últimas décadas ponen de relieve la necesidad de incorporar criterios éticos de responsabilidad. Esa incorporación permitirá el planteamiento de una inteligencia artificial responsable (IAR) que tendrá que fundamentarse en la formulación de un nuevo humanismo. Se entiende que a partir de un humanismo tecnológico se podría impulsar la IAR en el contexto tecnológico actual. Los desafíos de la IA imponen  el imperativo de plantear un humanismo de este tipo que asuma un compromiso con miras al futuro. En ese sentido, el humanismo tecnológico representa la exigencia de un tiempo de desafíos tecnológicos y a la vez una prem…

Estimating willingness to pay for desalinated seawater: the case of Djerba Island, Tunisia

2017

AbstractWater scarcity can be a growth-limiting factor. Non-conventional water resources, such as desalinated water, represent an alternative means of guaranteeing access to water while reducing water stress. In this study, a contingent valuation survey carried out in Djerba Island, Tunisia, allows the joint modelling of two decisions: societal support for the construction of a desalination plant and households’ willingness to pay for desalinated water. To the best of the authors’ knowledge, no study to date has addressed this relationship. We find that although a clear majority of households are in favour of using desalinated water, far fewer are willing to pay for it. The article conclude…

Pugnas por el control de la universidad después de la expulsión de los jesuitas

1990

Mi interés se centra en el análisis de los efectos del extrañamiento en los estudios universitarios y concretamente en Valencia. Resulta evidente que el decreto de extrañamiento produjo una efervescencia reformista en la Universidad. Es lógico porque, desde el momento en que empezó la campaña antijesuita, una de las razones alegadas fue la decadencia cultural que habían propiciado los padres de la Compañía a quienes se les atribuía el control de los instrumentos de poder. Así, los reformistas establecieron siempre una conexión entre la llegada al poder de los manteístas y la reforma de las letras. Desde esa perspectiva se comprende la expectación suscitada por el decreto de expulsión de los…

Crisis, convivencia multicultural y "efectos de barrio". El caso de dos barrios de Valencia

2015

La inserción urbana de los inmigrantes se desestabiliza y se pone a prueba con la crisis y las políticas aplicadas. Si bien en Valencia se mantiene una convivencia tranquila, la situación de los servicios públicos aumenta la competencia por recursos escasos entre vecinos de diferentes orígenes. Este texto presenta, en el marco de la ciudad de Valencia, un análisis comparativo de dos barrios receptores de inmigrantes que presentan fuertes contrastes. Por un lado, Russafa un barrio céntrico popular y en proceso de gentrification; por otro, Els Orriols, un barrio periférico obrero. Aún con muchos rasgos comunes, la intensidad del recelo hacia el inmigrante varía de un barrio a otro en función …
