information Title Remove Artifacts from a Single-Channel EEG Based on VMD and SOBI Author Changrui Liu; Chaozhu Zhang Journal Sensors Year 2022 DOI 10.3390/s22176698 abstract With the development of portable EEG acquisition systems, the collected EEG has gradually changed from being multi-channel to few-channel or single-channel, thus the removal of single-channel EEG signal artifacts is extremely significant. For the artifact removal of single-channel EEG signals, the current m ...

Bone Composition Bone tissue consists of cells embedded in an extracellular matrix (ECM). Bone is a living, dynamic tissue that is constantly being renewed. 10–15% of the bone in the whole body is replaced with new bone every year. Bone matrix contains not only an organic, collagen-based phase but also a mineral phase that provides bone with its characteristic rigidity and strength. This mineral phase is composed primarily of crystalline hydroxyapatite ([Ca3(PO4)2]3·Ca(OH)2), with small amounts ...

Know the hypotheses on the biomechanics of cartilage degeneration. Types of Cartilage The three main types of cartilage in the body are hyaline cartilage, elastic cartilage, and fibrocartilage. These cartilages differ in their proportions of collagen, elastin, and proteoglycans. hyaline cartilage透明软骨 Hyaline ...

Failure, Fracture, Fatigue Failure Failure Theory By material or structural failure, it is meant that the material either ruptures so that it can no longer support any load / undergoes excessive permanent deformation(yielding) ductile yield before fracture generally deform through shear in response to generalized states of stress brittle fracture before yield Brittle systems are weak in tension, and the generalized failure criterion is based on thenormal stress, or principal stresses, reachin ...

Elasticity pic1 pic2 pic3 pic4 take home message What are stress and strain? / 什么是应力和应变？ English Stress is the intensity of internal force over a section, or force per unit area. Normal stress is produced by a force perpendicular to the section and is denoted by σ. The average normal stress is σ = F / A. Tensile loading produces tensile stress, while compressive loading produces compressive stress. Tension is usually positive and compression is negative. Shear stress is produced ...
