The automatic logistics and warehousing handling robot AGV is equipped with non-contact control guide, and use a kind of storage battery as a power source. The computer-controlled automatic guiding AGV is developed on the basis of comprehensive analysis of advantages and disadvantages of various modes of guidance, combining absolute and relative positioning application, ultimately I choose the fusion...
Ocular rigidity is an important indicator describing the entirety elastic properties of the eyeball, which has a direct correlation with myopia and glaucoma. In this paper, how the intraocular pressures (IOP), central corneal thickness (CCT), and ages influenced ocular rigidity of New Zealand white rabbits was investigated. CCT and basic IOP were measured by the PachyMeter Echograph and Schiote Tonometer...
Abstract-In order to study the effects of aging on biomechanics properties, twenty rabbits with healthy eyes were divided into four groups including infancy (3 months), youth (5 months), midlife (18 months) and agedness (48 months). After measuring the central corneal thickness (CCT) and the intraocular pressure (IOP), the alteration of eye volume with intraocular pressure was determined of four different...
Based on CT scanning pictures from a volunteer's knee joint, a three-dimensional finite element model of the health human knee joint was constructed including complete femur, tibia, fibular, patellar and the main cartilage and ligaments. The model was validated by comparing with experimental and numerical results obtained from other authors. The pressure distribution of contact surfaces of knee joint...
A lens induce myopia model in 12 healthy guinea pigs was used in this study. For each guinea pig, one eye was selected randomly for myopia model, another served as a paired control. After 45 days, eye became myopic and elongated in myopia model. The alteration of eye volume with intraocular pressure was determined. Cornea and sclera strips were prepared for biomechanical properties measurement through...
In this paper, a three-dimensional (3D) FE model of the healthy human axis was built considered cortical and cancellous bone. The model was validated using numerical results obtained by other authors. The stress distribution and potential fracture patterns of the anterior odontoid were analyzed under different loading direction within coronal plane and sagittal plane. The direction of loading is the...
The development of pathological myopia is associated with reduced scleral collagen accumulation, scleral thinning, and loss of scleral tissue, in both humans and animal models. Posterior scleral reinforcement (PSR) was considered as an effective way for treating pathological myopia. Yet it is not well understood the possible role of collagen on the sclera reinforcement mechanisms in the PSR surgery...
