due to the rapid growth of the mining sector of Mongolia, the need for preparing mining surveying specialists is increasing significantly. The history of preparing highly educated mining surveying specialists and putting their education into practice in our country is an interesting one. The main center to prepare mining surveying specialists is the School of Mining Engineering of the Mongolian State University of Science and Technology. This paper introduces the work that is being done today to prepare mining surveying specialists in Mongolia and its future purposes.

To understand the principle and limitation of chalcogenide alloy Ge2Sb2Te5 （GST） in solid-state memory devices during crystallization, it was necessary to develop a physically realistic model that could reflect the electrical and thermal properties of these media. A novel comprehensive numerical model has been developed for simulating these memory devices, which describes the electrical and thermal behavior using the solution of the nonlinear, time-dependent electrical and heat conduction equation. The finite-difference-time-domain technique was adopted to compute the electrical field and heat distribution in the device. Several contributing factors that affect the crystallization switching process such as the geometry of the GST layer, temperature and electric field dependency of the electrical conductivity have been discussed. The results of the simulations were then used to provide critical guidelines for fabrication and optimization of the device performance.

This work aims at determining the overall response of a two-phase elastoplastic composite to isotropic loading. The composite under investigation consists of elastic particles embedded in an elastic perfectly plastic matrix governed by the Mohr-coulomb yield criterion and a non-associated plastic flow rule. The composite sphere assemblage model is adopted, and closed-form estimates are derived for the effective elastoplastic properties of the composite either under tensile or compressive isotropic loading. In the case when elastic particles reduce to voids, the composite in question degenerates into a porous elastoplastic material. The results obtained in the present work are of interest, in particular, for soil mechanics.

This work deals with the behavior of fermions in the background of kinklike structures in the twodimensional spacetime. The kinklike structures appear from bosonic scalar field models that engender distinct profiles and interact with the fermion fields via the standard Yukawa coupling. We first consider two models that engender parity symmetry, one leading to the exclusion of fermion bound states, and the other to the inclusion of bound states, when the parameter that controls the bosonic structure varies from zero to unity. We then investigate a third model where the kinklike solution explicitly breaks parity symmetry, leading to fermion bound states that are spatially asymmetric.

In many low-income countries, migrant remittances are essential in sustaining people's livelihoods and become even more important during and after ***, policymakers, and practitioners increasingly emphasize the need to better support this people-based mechanism, so disaster risk can be reduced. This suggests the importance of understanding migrants' perspectives on the remittance channels used and the challenges and opportunities of supporting remittances. However, such information is largely missing. drawing on interviews and a focus group discussion carried out with Pacific Island migrants living in New Zealand, the article identifies the capacity of migrants to utilize different remittance channels and resources to assist those affected in their country of origin. challenges faced include high transfer fees, lack of information and support from external stakeholders, and limited resources to effectively send both individual and collective remittances. The article concludes that there is a serious need to involve a large array of stakeholders in finding ways to better support remittances for disaster risk management, including migrants, government agencies, the private sector, nongovernmental organizations, and those receiving remittances.

In this,communication world, the Network Function Virtualization concept is utilized for many businesses, small services to virtualize the network nodefunction and to build a block that may connect the chain, communication ***, Virtualized Network Function Forwarding Graph (VNF-FG) has beenused to define the connection between the VNF and to give the best end-to-endservices. In the existing method, VNF mapping and backup VNF were proposedbut there was no profit and reliability improvement of the backup and mapping ofthe primary VNF. As a consequence, this paper offers a Hybrid Hexagon-costEfficient algorithm for determining the best VNF among multiple VNF and backing up the best VNF, lowering backup costs while increasing dependability. TheVNF is chosen based on the highest cost-aware important measure (cIM) rate,which is used to assess the relevance of the VNF forwarding *** achieveoptimal cost-efficiency, VNF with the maximum cIM is selected. After the selection process, updating is processed by three steps which include one backup VNFfrom one SFc, two backup VNF from one Service Function chain (SFc),and twobackup VNF from different SFc. Finally, this proposed method is compared withcERA, Mincost, MaxRbyInr based on backup cost, number of used PN nodes,SFc request utility, and latency. The simulation result shows that the proposedmethod cuts down the backup cost and computation time by 57% and 45% compared with the cER scheme and improves the cost-efficiency. As a result, this proposed system achieves less backup cost, high reliability, and low timeconsumption which can improve the Virtualized Network Function operation.

In this paper, we deal with nonlinear ill-posed problems involving m-accretive mappings in Banach spaces. We consider a derivative and inverse free method for the imple- mentation of Lavrentiev regularization method. Using general HSlder type source condition we obtain an optimal order error estimate. Also we consider the adaptive parameter choice strategy proposed by Pereverzev and Schock （2005） for choosing the regularization parameter.

As part of a research program, an extensive study on the dispersion characteristics of eight different7.62 ? 51 mm ammunition types was conducted. The paper presents the main steps in the experimental and analytical process carried out to evaluate, namely to measure and compare, the dispersion characteristics of the ammunitions; namely,(1) identify the number of rounds to fire in the trials,(2) establish a test plan and the setup for the precision trials,(3) fire the rounds, following an established protocol for the experiments,(4) collect the impact points, and measure the performance through statistical measures,(5) perform a statistical analysis of dispersion applied to the results obtained in the trials, and(6)conclude on the ammunition characteristics. In particular, the paper proposes a statistical method to evaluate the precision of ammunitions fired with precision(Mann) barrels. The practical method relies on comparison of confidence intervals and hypothesis testing on the standard deviation of samples,namely the impact points. An algorithm is proposed to compare the variances of two or more populations of ammunitions.
