Fabric Tensor for Discontinuous Geological Materials

Raman Spectroscopy for Geological Materials Analysis

Natural rocks composing the Earth are complex. They consist of an aggregate of one or more minerals. Each mineral can be defined by its chemical composition and its crystalline structure and sometimes can also contain fluid inclusions. Geologists need a powerful characterization technique to get detailed information on the rock formation history. Raman spectroscopy is extremely information-rich...

Defect Detection in Fabric Materials

This paper investigates various approaches for automated inspection of textured materials using Gabor filters. A new supervised defect detection approach is used to detect defect in textile web. Unsupervised web inspection is used with multichannel filtering scheme. This scheme establishes high computational savings and results in high quality of defect detection. The experimental results condu...

Fabric and Deformation in Granular Materials

The paper presents results of numerical experiments on a large assembly of smooth circular disks. The assembly was subjected to quasi-static biaxial loading at small to moderate strains by using the Discrete Element Method. Unlike the usual particle-based and coordination number approaches, the fabric was locally measured in relation to the shapes and orientations of voids. Deformation was meas...

Optimizing of Nonwoven Fabric Properties Using Nano-bio Materials for the Wound Dressing Application

Introduction: In addition to its protective role, dressings not only prevent infection, but also accelerate wound healing process. In this study, the influence of optimizing the properties of the calendered needle-punched nonwoven fabrics using the finishing materials of Honey, Aloe Vera, Chitosan and Nano Argentum Nitrate for the end-usage as dressing has been investigated. Methods: The prepa...
