Three-dimensional (3D) printing is a rapidly evolving technology with several potential applications in the diagnosis and management of cardiac disease. Recently, 3D printing (i.e. rapid prototyping) derived from 3D transesophageal echocardiography (TEE) has become possible. Due to the multiple steps involved and the specific equipment required for each step, it might be difficult to start impl...
In this work, Boltzmann transform has been used to analyze the problem of freezing of pure Aluminum in semi-infinite domain. The uniqueness of solution (solidification front location) has been proved using the characteristics of the functions appeared in solution. The effect of density change on temperature distribution and errors resulting from ignoring this change have been investigated. The ...
In this paper, the effect of the temperature change on the vibration frequency of mono-layer graphene sheet embedded in an elastic medium is studied. Using the nonlocal elasticity theory, the governing equations are derived for single-layered graphene sheets. Using Levy and Navier solutions, analytical frequency equations for single-layered graphene sheets are obtained. Using Levy solution, the...
introduction: three-dimensional (3d) scanners are widely used in medicine. one of the applications of 3d scanners is the acquisition of anthropometric dimensions for ergonomics and the creation of an anthropometry data bank. the aim of this study was to evaluate the precision and accuracy of a modified 3d scanner fabricated in this study. methods: in this work, a 3d scan of the human body was o...
conclusions iud displacement into the myometrium could be done in clinics, but advanced laparoscopy is needed for confirmed diagnosis and iud complication management. three- dimensional transvaginal ultrasound (3dtvus) clearly displays the correct position of the iud in the uterine cavity much better than the two-dimensional transvaginal ultrasound (2dtvus). introduction intrauterine devices (i...
