Environmental sustainability in non-residential buildings by automating and optimization LENI index
2018
Directive 2002/91 / EC as amended by 2010/31 / EU introduces procedures for energy certification aimed to determine, through the numerical indicators, the overall energy efficiency of the buildings, but notes the thermal and electric consumption. Often, the power consumption is incorrectly underestimated, this consumption would to be considered with great attention. In fact, compared to a committed capacity of less, compared to thermal plants, have times of utilization often far higher, leading to energy requirements to levels similar or even higher than those thermal, being the conversion factor of the electrical energy increasingly high. Leaving aside the procedural scheme energy certific…
Smart city and public lighting
2015
The smart city is increasingly becoming a concept of reference for what concerns the planning and the spatial development of cities. The concept of smart city cannot be easily standardized. It is based on a multi-service and multi-sectorial planning regarding various urban functions (energy, mobility, waste, etc.) and places them under a common denominator: the use of advanced technologies for minimizing resources consumption and simultaneously increase the quality of life of the citizens. This paper aims to give an overview on the concept of smart city and outline what, at present, are the main intervention areas considered at European level. Then the paper focuses on the public lighting t…
On the Applicability of the Space Syntax Methodology for the Determination of Street Lighting Classes
2020
Street lighting plays a crucial role in a city’s night landscape and in urban traffic management, influencing users’ comfort and safety. To contain costs of public street lighting systems and to avoid energy waste, illuminance levels on road surfaces must be adequate to fit actual traffic volumes, as prescribed by regulations. This is true not only for motorized roads but also for sidewalks, paths, and pedestrian areas. Regulations in force establish a relationship between road traffic volumes and minimum illuminance levels through the lighting classes selection procedure. Lighting classes selection is based on various para meters among which traffic volume is the most difficult to evaluate…
Linear transform for simultaneous diagonalization of covariance and perceptual metric matrix in image coding
2003
Two types ofredundancies are contained in images: statistical redundancy and psychovisual redundancy. Image representation techniques for image coding should remove both redundancies in order to obtain good results. In order to establish an appropriate representation, the standard approach to transform coding only considers the statistical redundancy, whereas the psychovisual factors are introduced after the selection ofthe representation as a simple scalar weighting in the transform domain. In this work, we take into account the psychovisual factors in the de8nition of the representation together with the statistical factors, by means of the perceptual metric and the covariance matrix, res…
Nightingale y la profesionalización de la enfermería en España
2021
espanolLa Historia de la Enfermeria Contemporanea en Espana esta siendo replanteada por multiples historiadores, que luchan contra las distorsiones que han desvirtuado la identidad enfermera en la historia. Teniendo como punto de partida la Escuela de Enfermeras de Santa Isabel de Hungria (1896), fundada por Rubio y Gali y tomando como referencia la Nightingale Training School (1860) fundada por Nightingale; el presente estudio muestra algunas de las evidencias sobre como la profesionalizacion de la Enfermeria en Espana siguio el mismo proceso que la enfermeria en otros paises. Analizando la informacion historica desde la perspectiva de genero, se muestra como el origen ideologico de la Enf…
Bullfighting: The Legal Protection of Suffering
2018
Bullfighting has been recently accepted as Cultural Heritage by the Spanish Government. There is a current initiative to declare bullfighting as Intangible Cultural Heritage (ICH) and include it in the UNESCO list. The proponents of such initiatives contend that bullfighting should be protected and promoted on the grounds that it is an artistic activity, part of the national culture. In this chapter, I discuss the moral arguments and legal aspects that can be pitted against such a cruel practice. More specifically, I will examine the serious obstacles to the legal protection of such practices, which cause suffering and aim at killing nonhuman animals based on cultural or artistic reasons.
The Diapause Lipidomes of Three Closely Related Beetle Species Reveal Mechanisms for Tolerating Energetic and Cold Stress in High-Latitude Seasonal E…
2020
During winter insects face energetic stress driven by lack of food, and thermal stress due to sub-optimal and even lethal temperatures. To survive, most insects living in seasonal environments such as high latitudes, enter diapause, a deep resting stage characterized by a cessation of development, metabolic suppression and increased stress tolerance. The current study explores physiological adaptations related to diapause in three beetle species at high latitudes in Europe. From an ecological perspective, the comparison is interesting since one species (Leptinotarsa decemlineata) is an invasive pest that has recently expanded its range into northern Europe, where a retardation in range expa…
Benefits of the European Agri-Environment Schemes for Wintering Lapwings : A Case Study from Rice Fields in the Mediterranean Region
2020
Mediterranean European rice fields provide important habitats for migrating waterbirds. In winter. one waterbird species that particularly benefits from rice fields is the Northern Lapwing (VaneIlus vanellas), a species threatened in Europe. To assess the effect of agii-environmental measures on rice field selection and use by wintering lapwings, bird counts were conducted in northeastern Spain during two consecutive winters (2005-2006 and 2006-2007). Information on two mandatory post-harvest management prescriptions of the agri-environment schemes was collected, namely winter flooding (percent ground surface covered by water) and whether fields were rolled or not. The number of lapwings in…
Regression diagnostics applied in kinetic data processing: Outlier recognition and robust weighting procedures
2010
An efficient protocol, based on advanced statistical diagnostics and robust fitting techniques applied to the least-squares processing of kinetic data of chemical reactions, is presented and discussed. The procedure, which is aimed at obtaining highly accurate estimation of the fitting parameters, consists of the identification of the outliers that remarkably impair the fitting by means of the so-called “leverage analysis” and some related diagnostics. This approach allows the elimination of the actually aberrant observations from the data set and/or their robust weighting to inhibit the negative effects induced on the data fitting, with consequent reduction of the bias introduced into the …
A Novel Self-organizing Neural Technique for Wind Speed Mapping
2009
Systems with high nonlinearities are, in general, very difficult to model. This is particularly true in geostatistics, where the problem of the estimation of a regionalized variable (RV) given only a small amount of measurement stations and a complex terrain surface is very challenging. This paper introduces a novel strategy, which couples the Curvilinear Component Analysis (CCA) and the Generalized Mapping Regressor (GMR). CCA, which is a nonlinear projector of a data manifold, is here used in order to find the intrinsic dimension of the data manifold, just giving an insight on the nonlinearities of the problem. This analysis drives the pre-processing of the data set used for the training …
