Minkyu Kwak, Bataa Lkhagvasuren, Xiuxiu SunWe propose a simple differential method and a refined Roonizi’s method to fit single Gaussian function and integrodifferential method to fit two Gaussian functions. The conventional method for fitting Gaussian functions is an iterative procedure. The proposed methods, being linear in estimated parameters, alleviate the problem of critical initial guess needed in iterative procedures. The experimental

Effect of Anisotropy on the Strength and Brittleness Indices of Laminated Sandstone Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20210215
Amin Jamshidi, Mehdi TorabiKaveh, Mohammad Reza NikudelThe strength and brittleness of rocks are among the most important mechanical parameters in the design of geotechnical projects. Anisotropy is one of the prominent factors affecting the rock properties including strength and brittleness. This paper investigates the effect of anisotropy on the strength and brittleness of laminated sandstone samples collected from the northwest of Khorramabad (west of

Genetic Diversity and DNA Barcoding of Wild Mushrooms from Northeast India Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20210213
Merilin Kakoti, Dibya Jyoti Hazarika, Amarendra Kumar, Madhumita Barooah, Mahendra Kumar Modi, Ashok Bhattacharyya, Robin Chandra BoroForest ecosystems of Northeast India are rich in the diversity of wild mushrooms. Few reports have demonstrated the diversity of wild mushrooms from this region on the basis of their morphology. This study reports the characterization of wild mushrooms collected from different locations of Northeast India based on their molecular information of the internal transcribed spacer (ITS) region. The identified

On the Eigenvalues of Some Signed Graphs Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20210210
M. Souri, F. Heydari, M. MaghasediLet G be a simple graph and A(G) be the adjacency matrix of G. The matrix \(S(G) = J I 2A(G)\) is called the Seidel matrix of G, where I is an identity matrix and J is a square matrix all of whose entries are equal to 1. Clearly, if G is a graph of order n with no isolated vertex, then the Seidel matrix of G is also the adjacency matrix of a signed complete graph \(K_n\) whose negative edges induce

Ab Initio Electronic Structure Investigation of AntimonyDoped SnO 2 (110) Nanosheet Iran. J. Sci. Technol. Trans. Sci. Pub Date : 20210207
Mahmoud Jafari, Somayeh Naseripour TakalloThe structural and electronic properties of the pure and Sbdoped SnO2 (110) nanosheet at four different concentrations of doping were investigated at the PW91 level of density functional theory. The Sb3Sn13O32 nanosheet was found to be the most stable compound due to having the lowest formation energy. Moreover, an increase in the concentration of Sb dopants reduces the bandgap of the pure nanosheet
