The study and development of an innovative material for building insulation is really important for a sustainable society in order to improve comfort and reducing energy consumption. The aim of this work is the development of insulating panels for sustainable buildings based on an innovative material made by cardboard and Phase Change Materials (PCMs). The research has consisted in laboratory t...

Controlled melting and solidification in encapsulated phase change materials (PCMs) is of practical interest, for example, latent heat storage applications. The choice PCMs the dynamic transfer characteristics during - affecting transient charging/discharging rates are decisive energy power density option. For highly conductive, high point (above 700 K) metal alloys have a potential advantage a...

Euclidean distance matrices (EDM) are symmetric nonnegative with several interesting properties. In this article, we introduce a wider class of called generalized (GEDMs) that include EDMs. Each GEDM is an entry-wise matrix. A not unless it EDM. By some new techniques, show many significant results on can be extended to matrices. These contain about eigenvalues, inverse, determinant, spectral r...

enterprise architecture (ea) is a discipline for understanding, engineering, and managing different components of an enterprise and their interrelationships. moreover, because the risk and impact of ea are pervasive across the enterprise, it is critical to perform an architecture assessment before making any decision about choosing a scenario. this paper provides an approach based on fuzzy anal...

Here we demonstrate the mechanical properties, thermal conductivity, and thermal energy storage performance of construction elements made of cement and form-stable PCM-Rubitherm® RT 28 HC (RT28)/expanded perlite (EP) composite phase change materials (PCMs). The composite PCMs were prepared by adsorbing RT28 into the pores of EP, in which the mass fraction of RT28 should be limited to be no more...

Nowadays, the energy consumption and production has considered as an interesting topic and debatable among researchers. The demand for generation of newer energy sources are increasing steadily day by day. This calls for design and development of novel energy saving devices in order to reduce the consumption of energy [1]. The enormous increase in production of greenhouse gases in atmosphere an...

In this paper we have raised, discussed, and solved the problems relating the Vargas's verification of consistency test for 3 x 3 comparison matrices in the Analytic Hierarchy Process (AHP). In the AHP community, assessing attribute weights by using a consistency ratio of 0.1 or less has been widely practiced. Though Vargas did study the problem, the method he adopted might lead to certain ques...
