Abstract Binarization plays an important role in document analysis and recognition (DAR) systems. In this paper, we present our winning algorithm ICFHR 2018 competition on handwritten image binarization (H-DIBCO 2018), which is based background estimation energy minimization. First, adopt mathematical morphological operations to estimate compensate the background. It uses a disk-shaped structuring element, whose radius computed by minimum entropy-based stroke width transform (SWT). Second,...
The relationship between support and surrounding rock is of great significance to the control in mining process. In view fact that most existing numerical simulation methods construct virtual elements stress servo approximately replace hydraulic problem, this paper establishes a new model with same working characteristics as actual by integrating software Rhino, Griddle FLAC3D, which can realize different conditions. Based on model, influence mechanism supporting strength regulation coal...
This article presents a numerical method for solving continuous time Markov chain (CTMC) model reliability evaluation of phased-mission system. The generates infinitesimal matrix based on the statistical independence subsystem failure and repair process. generator is stored by use sparse matrix-compressed storage schemes, transient solution CTMC obtained using three methods including uniformization method, forward Euler Runge-Kutta which take advantage sparseness matrix. An example PMS used...
Methanol-based physical absorption, known for its effective CO2 capture ability, has been employed in acid gas removal (AGR) unit. However, the high energy consumption associated cooling methanol and hampers widespread adoption. To address this challenge, numerous studies have explored use of nanoparticles to enhance absorption at room temperature, thereby reducing requirements. In study, objective is synthesize characterize Al2O3-methanol nanofluid investigate application a bubble column...
Summary The rheological properties of cement slurries usually vary greatly with the change temperature. This not only increases complexity cementing-job design, but also has side effects on cementing quality. To resolve this problem, a slurry temperature-insensitive viscosity been prepared by adding type thermosensitive controller (TVC). experiments show that relatively temperature-stable and shows very little thermal thinning between 20 120°C. In addition, thermally-stable-viscosity good...
Granite-related uranium ore is an important resource type in China and worldwide. Whether the geochemical theory “U6+ oxidative migration U4+ reductive precipitation” applicable to granite-related mineralization has not been determined. Detailed field petrographic work, as well scanning electron microscopy energy spectrum analysis, are conducted this study analyze relationship between minerals pyrite from different types evaluate mechanism for precipitation enrichment of Mianhuakeng deposit...
The compressive strength of filling body is an important index to characterize the and mining effect coal mine. In order accurately predict coal-based solid waste filler (CBSWF) guide safe, efficient, green mine, gangue used as coarse material; fly ash, desulfurization gypsum, gasification slag, furnace bottom slag are fine materials; cement gelling agent. bleeding rate CBSWF tested through orthogonal test, at different curing ages predicted by using a 4-11-3 three-layer BP neural network...
Carbonaceous material (CM) is common in meta-sediments and generally interpreted to be intimately associated with gold mineralization. For the Bumo deposit Hainan Province, South China, CM mainly hosted by greenschist facies—to amphibolite-facies metamophic rocks of Paleo—to Mesoproterozoic Baoban Group, auriferous veins which could used as an important prospecting indicator. However, genesis its relationship mineralization are still unclear. From field work thin section observations two...
