The structure of the human eye is almost spherical, elastic and the properties of the components are considerably age-related. The main parts of the eye are the sclera, the cornea, the ciliary muscle, the zonular fibers and the crystalline lens. We have built a complex three dimensional finite element model which contains the biologically and mechanically required parts for biomechanical analys...

Magnetic Resonance Imaging was used to study changes in the crystalline lens and ciliary body with accommodation and aging. Monocular images were obtained in 15 young (19-29 years) and 15 older (60-70 years) emmetropes when viewing at far (6 m) and at individual near points (14.5 to 20.9 cm) in the younger group. With accommodation, lens thickness increased (mean ± 95% CI: 0.33 ± 0.06 mm) by a ...

People rapidly and subconsciously process information from facial images. On sharing economy platforms, cues can provide a useful supplement to other provided by reputation systems. Previous small-scale, rater-informed studies examining trust attractiveness based on features Airbnb found mixed support for impacts pricing. We re-examine their impact using deep learning classify host faces an ext...

Pendidikan atau dalam hal ini adalah pedagogi turut menghadapi kendala saat pandemi Covid-19 terjadi, dampak terbesar dari dirasakan oleh baik siswa-siswi juga para pengajar guru-guru di sekolah. Pedagogi mengalami kondisi tidak biasa dan perlu beradaptasi dengan situasi pandemi, sehingga salah satu cara menyusun program pembelajaran daring (online) guru tetap bisa melangsungkan melanda. Persoa...

PURPOSE To quantify changes in crystalline lens curvature, thickness, equatorial diameter, surface area, and volume during accommodation using a novel two-dimensional magnetic resonance imaging (MRI) paradigm to generate a complete three-dimensional crystalline lens surface model. METHODS Nineteen volunteers, aged 19 to 30 years, were recruited. T(2)-weighted MRIs, optimized to show fluid-fil...

Introduction International Commission on Radiological Protection (ICRP) has provided a comprehensive discussion on threshold dose for radiation-induced cataract in ICRP publication 116. Accordingly, various parts of the eye lens have different radio-sensitivities. Recently, some studies have been performed to develop a realistic eye model with the aim of providing accurate estimation of fluence...

Steels with a mixed microstructure of allotriomorphic ferrite, bainitic ferrite, retained austenite and martensite have potentially good combinations of high strength and formability. This work describes a kinetic theory for the formation of bainite in steels where the precipitation of carbides is suppressed. The theory is based on the mechanism of transformation. It includes, for example, a nu...
