We give an alternative proof of the characterization of the semistable and the stable framed representations of a network quiver. This is a basic result for understanding the moduli spaces of neural networks which have been recently introduced.

The global bifurcation and chaotic dynamics of the symmetrically laid orthotropic composite rectangular laminated plate on four simply supported sides is investigated for the first time by means of making use of the generalized Melnikov method. By utilizing the coordinate transformation theory to obtain...

In this study, we present discretization schemes based on Generalized Integral Representation Method (GIRM) for numerical simulation of the Boussinesq wave. The schemes numerically evaluate the coupled Boussinesq equation for different solitary wave phenomena, namely, propagation of a single soliton,...

In this paper, the symmetry group method is used to study a new (2 + 1)-dimensional generalized KdV equation. The Lie point symmetries of (2 + 1)-dimensional generalized KdV equation are obtained. Symmetry reductions and several interesting explicit solutions to the (2 + 1)-dimensional generalized KdV...

We study a class of time fractional diffusion-wave equations with variable coefficients using Lie symmetry analysis. We obtain not only infinitesimal symmetries but also a complete group classification and a classification of group invariant solutions of this class of equations. Group invariant solutions...

This study introduces an efficient and highly accurate quintic B-spline method for solving Lane-Emden type equations which represent many scientific phenomena in astrophysics and mathematical physics. The main advantage of the obtained quintic spline is that it approximates not only a solution of the...

The melanin of yak hair is a biomaterial with unique features and functions. We investigated the properties of woolen woven when coated with yak hair melanin. Natural melanin was extracted from yak hair by the method of acid hydrolysis. The woolen woven was coated with 5%-10% owt melanin, 0.8 g/l sodium...

This study has been developed for the synthesis of hydroxyapatite using low-cost dolomite material. We investigated the influence of calcination temperature and feed gases on the decomposition of raw dolomite, and the relation between the calcination temperature and the phosphorus affinity. Also, the...

In this work, we studied the thermal cracking of atmospheric residue from Tamsagbulag crude oil in the presence of hydrogen donor-decalin. The oil is highly paraffinic and has high a viscosity and low yield of distillate fraction. Therefore, deep processing is necessary to increase the yield of distillate...

Incorporation of high aspect ratio nanoparticles can significantly increase mechanical properties such as elastic modulus and tensile strength, and the functionality of the obtained nanocomposites. In this work, organically modified montmorillonite (Closite 30B) is dispersed and simultaneously oriented...

This research work completed the study of obtaining zeolite by hydrothermal method using the ash of Erdenet Thermal Power Plant. According to the results of the study, the ratio of macroelements of ash in the ash pond of Erdenet Thermal Power Plant is less than 1, so it belongs to acid ash. Also, based...

The present research work deals with the behavior of the thermal decomposition of the coals from Shivee-Ovoo and Tavantolgoi deposits and the determination of the kinetic parameters of their thermal decomposition. Thermal decomposition experiments were performed at five different heating temperature...

In frame of De Launay model we calculated phonon dispersion of graphene in ГM direction using radial and tangential force constants for first four neighbor atoms. Calculated phonon dispersion is in satisfactory agreement with experimental phonon spectra of graphite. In long wave approximation we estimated...

The site-site Ornstein-Zernike equation combined with the Verlet-modified bridge function has been applied to the binary hard sphere mixtures and pressure consistency has been tested. An equa tion of state has been computed for the case where a packing fraction is η = 0.49, diameter ratios are σ2/σ1 = 0.3...

The photoionization cross section (PCS) of a hydrogenic-like impurity in a piezoelectric core-shell nanowire is investigated by a variational method combined with a finite-difference algorithm. The quantum Stark effect caused by the piezoelectric field, the quantum confinement effect due to structural...

In order to determine the critical pH for acid failure and establish the optimal operating condition for the VFA recovery reactor, the existing model was refined by incorporating a pH suppression equation. Through simulation of experimental data from other researchers, a range of pH parameters were identified...

This article considers measures to reduce air pollution from autonomous heating facilities. At the present time autonomous heat supply is actively developing. Affordability, controllability, autonomy, economy allow to determine the choice of consumers. But unlike power plants, the design of small boiler...

Smart grid technology uses for all levels of energy sector, its including energy production, energy distribution, energy transmission and energy users. Specially, research of smart technology usage for energy saving issue is one of the important things in this sector. In addition, researches appeared...

In Mongolia, construction work in the coldest months of the year decreases dramatically due to a lack of reliable technology methods for cold weather concreting. Last 10 to 15 years, the convective heating method has started to be dominantly used in cold weather concreting in the country but comprehensive...

Material cost is almost 50–60% of most construction projects. In recent years, the price of building materials and the supply has decreased, directly affecting the construction cost. This study aims to identify the main factors supply of materials affecting the construction industry in Mongolia. A quantitative...

The optimal scheduling of the electricity market requires a holistic approach that incorporates demand-side measures, energy storage systems, renewable energy integration, market mechanisms, and system operations. The power system can achieve greater flexibility, reliability, and efficiency by leveraging...

The objective of this study described in this paper is to grasp the ultimate moment capacity of 50 m prestressed ultra-high-performance fiber-reinforced concrete (UHPFRC) composite box girder. The uniqueness of the prestressed UHPFRC composite box girder is no longitudinal reinforcement and no stirrups...
