| This is Part 1 of a two part paper on the design of intelligent controllers for a class of exercise machines. The control objective is to cause the user to exercise in a manner which optimizes a criterion related to the user's mechanical power. The optimal exercise strategy is determined by a biomechanical behavior of the individual user, which is assumed to satisfy an aane force-velocity rel...

The temporomandibular joint (TMJ) disc consists mainly of collagen fibers and proteoglycans constrained in the interstices of the collagen fiber mesh. This construction results in a viscoelastic response of the disc to loading and enables the disc to play an important role as a stress absorber during function. The viscoelastic properties depend on the direction (tension, compression, and shear)...

BACKGROUND The biomechanical property of the periodontal ligament (PDL) is important in orthodontics and prosthodontics. The objective of this study was to evaluate the feasibility of measuring the biomechanical behavior of the periodontal ligament using micro-computed tomography (micro-CT). METHODS A custom-made apparatus measured the force and displacement of a porcine PDL specimen within t...

BACKGROUND Distal radius fractures (DRF) are one of the most common fractures and often need surgical treatment, which has been validated through biomechanical tests. Currently a number of different fracture models are used, none of which resemble the in vivo fracture location. The aim of the study was to develop a new standardized fracture model for DRF (AO-23.A3) and compare its biomechanical...

A method is presented for studying and quantifying the biomechanical behavior of the human eye under elevated fluid and structural pressure loading. The approach taken involves a coupled synergistic computer modeling and experimental effort in which numerical models are used to predict the biomechanical response of eye under pressure, and physical cadaveric eye models along with appropriate ima...

background: plasterers are at risk of musculoskeletal disorders (msds) due to the nature of their occupation and ergonomic factors. the purpose of this study was to evaluate the biomechanical risk factors for msds among plasterers. materials and methods: in this descriptive study, 70 plasterers from neyshabur, iran, were studied in 2014. the nordic musculoskeletal questionnaire (nmq) was used t...

Nanotechnology which involves handling with materials at very small dimensions (10-9m) has wide applications in engineering branches. It can improve the physical and chemical properties of the system. Thus it has many applications such as solar desalination [1] and many others. Current researches are trying to involve these substances in biomechanical engineering systems. For example one of imp...

We propose computer vision-based biomechanical analysis for construction field workers. Taking into account the fact that the number of fatalities in construction is the highest among all industries [1], and that the unsafe acts and behavior of workers cause 80% to 90% of accidents in construction [3,5,7], the systematic understanding of field construction workers’ unsafe behavior has great pot...

conclusions in contrast to the findings in humans and certain other species, glucocorticoid administration caused anabolic effect on the cortical bone of tibia diaphysis bone in rats. results glucocorticoid-treated rats showed weight loss and considerable mortality (21%). the biomechanical properties (maximum force) of glucocorticoid-treated rats in groups 4 (62 ± 2.9), 6 (63 ± 5.1), and 7 (60 ...
