A new 2D-hybrid model in cylindrical coordinates intended for the study of a transient magneto-thermal coupled problem is proposed. This used to evaluate spatiotemporal distribution temperature rotating aluminum billets heated by permanent magnets induction-heating device (PMIHD). The proposed hybrid consists coupling an exact analytical solution 2D magneto-harmonic field thermal analysis where...
We propose a new method to measure the myocardial FDG uptake during fasting and glucose loading in one day, a myocardial FDG-PET one-day protocol, with both 2- and 3-dimensional data acquisition (2D and 3D) without background activity subtraction. To confirm it, we evaluated the effect of scatter correction in the 2D and 3D modes of a PET scanner both in phantom and patient studies. In the phan...
Hybrid Reality Environments represent a new kind of visualization spaces that blur the line between virtual environments and high resolution tiled display walls. This paper outlines the design and implementation of the CAVE2 TM Hybrid Reality Environment. CAVE2 is the world’s first near-seamless flat-panel-based, surround-screen immersive system. Unique to CAVE2 is that it will enable users to ...
When non-neutral plasma columns are subject to azimuthally asymmetric electrostatic potentials, they deform into azimuthally asymmetric shapes. A typical asymmetric shape is shown in Fig. 1. The companion paper presents methods of predicting the form of these shapes. Here we analyze the shapes’ stability. Stability is normally studied through modal analysis, in which nonlinear equilibria are ca...
Recently, a high frame rate (HFR) imaging method based on limited diffraction beam (LDB) theory has been developed. In this method, a twodimensional (2D) or three-dimensional (3D) image is constructed with a single plane wave transmission and thus a theoretical frame rate of 3750 frames/second can be obtained for biological soft tissues at a depth of about 200 mm. Because a plane wave is used t...
