A constitutive model with capacity to simulate the full deformation and failure process for rocks considering initial compression residual strength behaviors is discussed in this paper. The rock was assumed consist of voids portion solid skeleton portion. can be established by consideration macroscopic microscopic deformations two different portions based on statistical damage theory. Comparisons between experimental data from triaxial tests calculated results show that proposed provided a...
In the past year, Multimodal Large Language Models (MLLMs) have demonstrated remarkable performance in tasks such as visual question answering, understanding and reasoning. However, extensive model size high training inference costs hindered widespread application of MLLMs academia industry. Thus, studying efficient lightweight has enormous potential, especially edge computing scenarios. this survey, we provide a comprehensive systematic review current state MLLMs. Specifically, summarize...
Diffusion Transformers (DiTs) have shown remarkable performance in modeling and generating high-quality videos. However, the quadratic computational complexity of 3D full attention mechanism presents significant challenges scaling video DiT training, especially for high-definition lengthy videos, where can dominate up to 95% end-to-end time necessitate specialized communication paradigms handle large input sizes. This paper introduces DSV, a novel framework designed accelerate scale training...
This study numerically investigates the failure processes of recycled aggregate concrete (RAC) and natural (NAC). A two-dimensional simulation based on a discrete-element method (DEM) is conducted with universal distinct-element code (UDEC) program. RAC modeled by combination rigid Voronoi blocks cemented to each other using contacts for interfaces. The determination procedure contact microparameters analyzed, series microscopic parameters in different components (MRAC) calibrated...
The coupled discrete-element method–finite difference method (DEM–FDM) numerical modeling scheme was proposed to simulate a single stone column in soft clay according the Universal Distinct Element Code (UDEC). discrete granular materials that form can be better simulated by DEM model, which extends beyond capability of continuum approaches. In DEM–FDM represented rigid blocks Voronoi tessellation, and surrounding as continuous Mohr-Coulomb material. settlement, bulging deformation, failure...
The axial loading test on a geogrid-encased stone column has been simulated using 3D numerical model in the proposed study. was modeled discrete element method (DEM), and geogrid by shell-type encasement finite difference (FDM). nonspherical rigid particles considering actual shape size distribution of gravel, which better represents nature columns. rationality successfully verified experimental results from previous test. complete deformation failure process well captured. have discussed at...
Landslide susceptibility mapping (LSM) is a cost-effective tool for landslide hazard mitigation. To date, no nationwide maps have been produced the entire Kenyan territory. Hence, this work aimed to develop map at national level in Kenya using fuzzy analytic hierarchy process method. First, hierarchical evaluation index system containing 10 contributing factors and their subclasses was established produce map. Then, weights of these indexes were determined through pairwise comparisons, which...
This paper investigates the failure processes of recycled aggregate concrete by a model test and numerical simulations. A micromechanical modeling approach to simulate progressive cracking behavior modeled concrete, considering its actual meso-structures, is established based on discrete element method (DEM). The determination procedure contact microparameters analyzed, series microscopic parameters for different components (MRAC) calibrated using nanoindentation results. complete...
The relationship between moisture transportation and efflorescence in sodium hydroxide- or silicate-activated fly ash/slag geopolymers was investigated. results show that the products are carbonate hydrates, mainly composed of natron, heptahydrate, trona carbonate. induces compressive strength loss, water absorption increases pore structure degradation geopolymer. When curved surface a geopolymer cylinder is covered with plastic film, drives free alkalis to top initiate efflorescence. In...
This study introduces a novel method for particle abrasion derived from fundamental natural phenomena and mechanical principles, allowing precise control over the degree of more accurately mimicking processes. The method's validity is confirmed using specific shape index. Through conventional triaxial tests, behavior granular aggregates with varying degrees was analyzed. findings indicate that increased leads to decrease in average coordination number sliding amount, while rotation amount...
