Automatic and high quality hexahedral meshing of complex solid models is still a challenging task. To guarantee the quality of the generated mesh, current commercial software normally requires users to manually decompose a complex solid model into a set of simple geometry like swept volume whose high quality hexahedral mesh can be easily generated. The manual decomposition is a time-consuming p...

Background: The course of acute Vogt-Koyanagi-Harada is typically assessed qualitatively using indocyanine green angiography. Swept-source optical coherence tomography may provide a safer, non-invasive, more objective approach to follow up. In this study, we assess the clinical value of the automated measurement capabilities of swept-source tomography to measure choroidal thickness. Design: Pro...

G. Elber Dept. of Computer Science, Technion, Haifa, 32000, Israel [email protected] Abstract We present an efficient and robust algorithm for computing the perspective silhouette of the boundary of a general swept volume. We also construct the topology of connected components of the silhouette. At each instant t, a three-dimensional object moving along a trajectory touches the envelope...

of a thesis at the University of Miami. Master’s thesis supervised by Professor Ozcan Ozdamar. No. of pages in text. (53) Otoacoustic Emissions (OAE) are minute acoustic responses originating from the cochlea as a result of an external acoustic stimulus and are recorded using a sensitive microphone placed in the ear canal. OAEs are acquired by synchronous stimulation with an acoustic click or t...

A real–time surface interpolator is developed, to machine a family of swept surfaces directly from their high–level procedural definitions. All the computations required for machining are performed in real time based on the exact surface geometry, including tool path planning, tool path interpolation, tool offsetting, and tool path step–over to achieve a prescribed scallop height. A G–code comm...

In this paper, optimum positioning of the conical cutter for five-axis flank milling of slender surfaces is addressed from the perspective of approximating the tool envelope surface to the data points on the design surface following the minimum zone criterion recommended by ANSI and ISO standards for tolerance evaluation. Based on the observation that a conical surface can be treated as a canal...

Dr. Jinesh Machchhar Computer Science Department, Technion-Israel Institute of Technology Precise Algebraic-based Swept Volumes for Arbitrary Free-form Shaped Tools towards Multi-axis CNC Machining Verification This work presents an algebraic based approach and a computational framework for the simulation of multiaxis CNC machining of general freeform tools. The boundary of the swept volume of...

Although stimulus-frequency otoacoustic emissions (SFOAEs) offer compelling advantages as noninvasive probes of cochlear function, they remain underutilized compared to other evoked emission types, such as distortion-products (DPOAEs), whose measurement methods are less complex and time-consuming. Motivated by similar advances in the measurement of DPOAEs, this paper develops and characterizes ...
