| 1 | Strategic mining options optimization:Open pit mining, underground mining or both显示文摘Near-surface deposits that extend to considerable depths are often amenable to both open pit mining and/or underground mining. This paper investigates the strategy of mining options for an orebody using a Mixed Integer Linear Programming(MILP) optimization framework. The MILP formulation maximizes the Net Present Value(NPV) of the reserve when extracted with(i) open pit mining,(ii) underground mining, and(iii) concurrent open pit and underground mining. Comparatively, implementing open pit mining generates a higher NPV than underground mining. However considering the investment required for these mining options, underground mining generates a better return on investment than open pit mining. Also, in the concurrent open pit and underground mining scenario, the optimizer prefers extracting blocks using open pit mining. Although the underground mine could access ore sooner, the mining cost differential for open pit mining is more than compensated for by the discounting benefits associated with earlier underground mining. | Ben-Awuah Eugene Richter Otto Elkington Tarrant Pourrahimian Yashar | 2016 | International Journal of Mining Science and Technology2016，26，6： | 15 |
| 2 | A multi-step approach for block-cave production scheduling optimization显示文摘Production schedules that provide optimal operating strategies while meeting practical,technical,and environmental constraints are an inseparable part of mining operations.Relying only on manual planning methods or computer software based on heuristic algorithms will lead to mine schedules that are not the optimal global solution.Mathematical mine planning models have been proved to be very effective in supporting decisions on sequencing the extraction of material in mines.The objective of this paper is to develop a practical optimization framework for caving operations’production scheduling.To overcome the size problem of mathematical programming models and to generate a robust practical near-optimal schedule,a multi-step method for long-term production scheduling of block caving is presented.A mixed-integer linear programming(MILP)formulation is used for each step.The formulations are developed,implemented,and verifed in the TOMLAB/CPLEX environment.The production scheduler aims to maximize the net present value of the mining operation while the mine planner has control over defned constraints.Application and comparison of the models for production scheduling using 298 drawpoints over 15 periods are presented. | Yashar Pourrahimian Hooman Askari-Nasab Dwayne D.Tannant | 2013 | International Journal of Mining Science and Technology2013，23，5： | 13 |
| 3 | Review-material degradation assessed by digital image processing:Fundamentals,progresses,and challenges显示文摘Material degradation is accompanied by the changes in surface structure,morphology,and composition.These changes can be recorded by a variety of image acquisition devices that export digital images in grayscale or true color to a detector.Information regarding corrosion type and extent can be extracted with image processing methods.This paper provides a comprehensive review of material degradation assessed by digital image processing.Digital image processing systems used to assess material degradation are briefly reviewed,and the algorithms developed to process metallic materials degradation images are described.Physical and electrochemical methods that can be used to support digital image processing results are summarized,and future work that will augment the present methods of evaluating material degradation are discussed. | Da-Hai Xia Shizhe Song Lei Tao Zhenbo Qin Zhong Wu Zhiming Gao Jihui Wang Wenbin Hu Yashar Behnamian Jing-Li Luo | 2020 | Journal of Materials Science & Technology2020，52，18： | 8 |
| 4 | Deep learning approach based on dimensionality reduction for designing electromagnetic nanostructures显示文摘In this paper,we demonstrate a computationally efficient new approach based on deep learning(DL)techniques for analysis,design and optimization of electromagnetic(EM)nanostructures.We use the strong correlation among features of a generic EM problem to considerably reduce the dimensionality of the problem and thus,the computational complexity,without imposing considerable errors.By employing the dimensionality reduction concept using the more recently demonstrated autoencoder technique,we redefine the conventional many-to-one design problem in EM nanostructures into a one-to-one problem plus a much simpler many-to-one problem,which can be simply solved using an analytic formulation. | Yashar Kiarashinejad Sajjad Abdollahramezani Ali Adibi | 2020 | npj Computational Materials2020，，1： | 8 |

| 6 | Landfill site selection using multi cr iter ia decision making: Influential factors for comparing locations显示文摘Although a lot of research has focused on energy recovery and recycling of valuable materials from wastes to reduce loads on landfills,landfilling is still an inseparable part of solid waste management.Since landfills potentially pose a risk to human health and the surrounding environment,landfill site selection is an important endeavor that has to be carried out with great care.Choosing a suitable location for landfills depends on several factors and is a complicated procedure.In this paper,a comprehensive review of landfill site selection methods,with an emphasis on multi criteria decision making(multiple criteria decision analysis)has been presented.Assessments indicate that the most frequently used methods are weighted linear combination(WLC),ordered weighted averaging(OWA),analytic hierarchy process(AHP),fuzzy analytic hierarchy process(F-AHP),TODIM,fuzzy TODIM,analytic network process(ANP),fuzzy-analytic network process(F-ANP),and grey systems theory,each of which is discussed.The most widely used factors for selecting a landfill site are groundwater depth,surface water vicinity,elevation,land slope,soil permeability,soil stability,flooding susceptibility,lithology and stratification,faults,land use type,nearby settlements and urbanization,cultural and protected site vicinity,wind direction,roads,railways,proximity to building materials,pipelines and powerlines,and proximity to airports. | Yashar Rezaeisabzevar Alireza Bazargan Behzad Zohourian | 2020 | Journal of Environmental Sciences2020，32，7： | 5 |
| 7 | Optimizing illumination's complex coherence state for overcoming Rayleigh's resolution limit显示文摘We suggest tailoring of the illumination's complex degree of coherence for imaging specific two-and three-point objects with resolution far exceeding the Rayleigh limit.We first derive a formula for the image intensity via the pseudo-mode decomposition and the fast Fourier transform valid for any partially coherent illumination(Schell-like,non-uniformly correlated,twisted)and then show how it can be used for numerical image manipulations.Further,for Schell-model sources,we show the improvement of the two-and three-point resolution to 20%and 40%of the classic Rayleigh distance,respectively. | 梁春豪 Yashar E.Monfared 刘欣 齐宝鑫 王飞 Olga Korotkova 蔡阳健 | 2021 | Chinese Optics Letters2021，19，5： | 2 |
