Macroscopic expressions of molecular adiabatic compressibility of methyl and ethyl caprate under high pressure and high temperature
2014
The molecular compressibility, which is a macroscopic quantity to reveal the microcompressibility by additivity of molecular constitutions, is considered as a fixed value for specific organic liquids. In this study, we introduced two calculated expressions of molecular adiabatic compressibility to demonstrate its pressure and temperature dependency. The first one was developed from Wada’s constant expression based on experimental data of density and sound velocity. Secondly, by introducing the 2D fitting expressions and their partial derivative of pressure and temperature, molecular compressibility dependency was analyzed further, and a 3D fitting expression was obtained from the calculated…
Impact of a Social Constructivist Instructional Strategy on Performance in Algebra with a Focus on Secondary School Students
2020
There have been perennial concerns on the low academic performance of students among researchers and other education stakeholders. Innovative teaching strategies have, therefore, gained prominence in the field of mathematics education. The purpose of this study is to investigate the impact of a social constructivist instructional strategy on students’ performance in algebra. The present study is quasi-experimental, and its type is a posttest control group involving 154 secondary school students that are randomly selected across four intact classes. The random selection of students to treatment and control controls is assumed to improve the validity of the results. Two research questions are…
An ANN model to correlate roughness and structural performance in asphalt pavements
2017
Abstract In this paper, using a large database from the Long Term Pavement Performance program, the authors developed an Artificial Neural Network (ANN) to estimate the structural performance of asphalt pavements from roughness data. Considering advantages of modern high-performance survey devices in the acquisition of road pavement functional parameters, it would be of practical significance if the structural state of a pavement could be estimated from its functional conditions. To differentiate various road section conditions, several significant input parameters, related to traffic, weather, and structural aspects, have been included in the analysis. The results are very interesting and …
Development of Eco-Friendly and Self-Cleaning Lime-Pozzolan Plasters for Bio-Construction and Cultural Heritage
2020
Summarization: Nowadays, the design and use of multi-functional mortars has increased significantly, with interesting applications in the green building and cultural heritage conservation sectors. A key point for a correct adoption of these innovative materials is their behavior along time and their resistance to the weathering. The objective of this project was to define the performance and durability of innovative mortars, in order to use them correctly and to avoid irreparable damage over time. For the development of this project, lime–metakaolin and hydraulic lime–metakaolin based mortars (hereinafter called A, B), as well as A and B with the addition of nano-TiO2 and perlite (hereinaft…
Constitutional Perspective of the Guarantees of Application of Artificial Intelligence: the Inescapable Protection of Fundamental Rights
2020
espanolLa Inteligencia Artificial tiene un innegable efecto en la sociedad actual, por lo que su estudio respecto de sus efectos juridicos deviene necesario. Y, en consecuencia, el modo en que se ven afectados los derechos fundamentales tiene especial importancia. De ahi que en el presente trabajo se estudie la influencia de los algoritmos en la determinacion de las resoluciones judi-ciales, sobre todo desde el punto de vista de como afectaria esta cuestion al derecho a la tutela judicial efectiva, reconocida como derecho fundamental en el articulo 24 de la Constitucion espanola. EnglishArtificial Intelligence has an undeniable effect on today’s society, so its study regarding its legal eff…
Application of optimized artificial intelligence algorithm to evaluate the heating energy demand of non-residential buildings at European level
2019
Abstract A reliable preliminary forecast of heating energy demand of a building by using a detailed dynamic simulation software typically requires an in-depth knowledge of the thermal balance, several input data and a very skilled user. The authors will describe how to use Artificial Neural Networks to predict the demand for thermal energy linked to the winter climatization of non-residential buildings. To train the neural network it was necessary to develop an accurate energy database that represents the basis of the training of a specific Artificial Neural Networks. Data came from detailed dynamic simulations performed in the TRNSYS environment. The models were built according to the stan…
Multiple criteria assessment of methods for forecasting building thermal energy demand
2020
Abstract Nowadays worldwide directives have focused the attention on improving energy efficiency in the building sector. The research of models able to predict the energy consumption from the first design and energy planning phase is conducted to improve building sustainability. Use of traditional forecasting tools for building thermal energy demand tends to encounter difficulties relevant to the amount of data required, implementation of the models, computational costs and inability to generalize the output. Therefore, many studies focused on the research and development of alternative resolution methods, but the choice of the most convenient is not clear and simple. Single comparison of s…
The shaping of public economic discourse in postwar America: the 1947 meat shortage and Franco Modigliani's meat plan
2015
This paper discusses the American debate over price controls and economic stabilization after World War II, when the transition from a war economy to a peace economy was characterized by bottlenecks in the productive system and shortages of food and other basic consumer goods, directly affecting the living standard of the population, the public opinion, and political discourse. Specifically, we will focus on the economist Franco Modigliani and his proposal for a "Plan to meet the problem of rising meat and other food prices without bureaucratic controls." The plan prepared by Modigliani in October 1947 was based on a system of taxes and subsidies to foster a proper distribution of disposabl…

Construct Validity of Rizzo et al.'s (1970) Role Conflict and Ambiguity Scales: A Multisample Study
1998
La validite de construction des echelles de Rizzo, House, et Lirtzman (1970) a ete fortement critiquee ces dernieres annees. Les critiques portent sur la formulation des items qui constituent ces echelles, ce qui fait que l'interpretation des echelles depend totalement de la formulation des items. Ces critiques ont favorise l'emergence d'autres modeles factoriels. La duplication elargie de Kelloway et Barling (1990), l'analyse factorielle destinee a confirmer la validite des echelles de Rizzo et al. et une echelle de surcharge des roles avec des items formules a la fois affirmativement et negativement furent utilisees pour eprouver la validite de construction des echelles d'ambiguite et de …
