Background: This study describes the possibility of implementing three-dimensional printing technology to create a precise construction of a planned bolus, based on computed tomography information stored in the Digital Imaging and Communications in Medicine (DICOM) format file. Materials and Methods: To create the bolus with a 3D printer, we converted data in the DICOM format to the s...
dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. this study is aimed to elaborate this notion in the case of three dimensional (3d) walking and extend it f...
The influx of consumer-grade 3D printers has changed the potential user base for computer-aided drafting (CAD) software. No longer are 3D models solely the work of engineers and animators. We now see hobbyists, educators, and even children generating 3D-printed objects, however, there is a significant skill gap between the novice 3D printer user and the expert designer. Filling that gap is a gr...
A combination of 3D modeling and high-throughput sequencing may offer a faster way to determine the three-dimensional structures of RNA molecules.
This work presents a new framework for three-dimensional modeling of dynamic fires present in unstructured scenes. The proposed approach addresses the problem of segmenting fire regions using information from YUV and RGB color spaces. Clustering is also used to extract salient points from a pair of stereo images. These points are then used to reconstruct 3D positions in the scene. A matching st...
Abstract A three-dimensional model of intense bunched beams is developed for cylindrical and corrugated conducting pipes. Updated comparisons between the current limits derived from this model and experimental data from PPM focusing klystrons are presented. An electrostatic Green’s function is formulated for azimuthally symmetric slowwave structures. Analytical and numerical results are present...
In this paper the application of a novel CW FM Laser radar is demonstrated through the acquisition of a three dimensional model of the world famous "David" by Donatello. The steps of the acquisition procedure and the related technical solutions are reported. The scientific focus was centered on the processing pipeline simplification due to this new acquisition methodology. Detailed results are ...
