The quantitative study of the activity of single neurons in sensory systems has been a subject of increasing interest in recent years. As a result there are a number of statistical tools suitable for analyzing the patterns of neuronal activity from both receptors and higher-order cells 1. This has contributed to a greater understanding of the detailed mechanisms of sensory transduction and codi...

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 ...

Purpose. To introduce a new anterior segment optical coherence tomography parameter, trabecular-iris circumference volume (TICV), which measures the integrated volume of the peripheral angle, and establish a reference range in normal, open angle eyes. Methods. One eye of each participant with open angles and a normal anterior segment was imaged using 3D mode by the CASIA SS-1000 (Tomey, Nagoya,...

We present two-dimensional hydrodynamical simulations of both jet-and wind-driven models for protostellar outflows in order to make detailed comparisons to the kinematics of observed molecular outflows. The simulations are performed with the ZEUS-2D hydrodynamical code using a simplified equation of state, simplified cooling and no external heating, and no self-gravity. In simulations of steady...
