We consider flow-through systems in which the characteristic length is limited such that turbulent flow is not reached even at high fluid velocities, i.e., the flow remains laminar. In these flow regimes, inducing circulation or vortices in the flow enhances mixing and heat transfer [1]. These can be created by placing obstacles in the flow path, for example. Figure 1. Geometry of the simulatio...

This paper discusses the conditions for undershoot responses in a circular path-following vehicle control. As method to follow path, it is known combine rotational and expansionary coordinate transformation kinematic model. However, which output moves opposite direction reference value occurred under certain initial of vehicle. It necessary clarify cause because delay time following value. The ...

In this paper, a Fuzzy-Obstacle-Avoidance-Path (FOAP) algorithm for the obstacle avoidance and a procedure for the shooting action of the robot soccer based on this algorithm are proposed. This algorithm contains a fuzzy system that is used to estimate the rotational velocity of the robot soccer. To demonstrate the effectiveness and applicability of the proposed method, two simulations are pres...

The general ring laser operation model is adopted for the large gyroscopes C-II and G. An extended set of auxiliary sensors information is used for the long time period data modeling and ring laser behavior analysis with respect to the ideal case. Both instrumental errors and orientational effects are estimated and compensated where possible. The instrumental stability improved approximately fo...

Matthew S. Allen Assistant Professor [email protected] Department of Engineering Physics University of Wisconsin-Madison 535 Engineering Research Building 1500 Engineering Drive Madison, WI 53706 Abstract A laser Doppler vibrometer typically measures the translational velocity at a single point along the direction of incident light. However, it has been shown that rotational velocities can ...

Recent studies have suggested that humans cannot estimate their direction of forward translation (heading) from the resulting retinal motion (flow field) alone when rotation rates are higher than approximately 1 deg/sec. It has been argued that either oculomotor or static depth cues are necessary to disambiguate the rotational and translational components of the flow field and, thus, to support...

The rotational spectrum of S4 has been observed for the first time in an electrical discharge through sulfur vapor. Two techniques have been used: Fourier transform microwave spectroscopy and long-path millimeter-wave absorption spectroscopy. Small, but systematic shifts of the measured transition frequencies of the normal isotopic species indicate that S4 has C2v symmetry but with a low-lying ...

This paper present a simulation of motion interpretation of trochoid path generated by a single point on a rotating disc translating in the frontoparallel plane of the visual eld. The process involves two mechanisms. First, the extraction of relative motion in a group motion and second the presence an attention mechanism. Speci cally, the paper present neural simulation results for cycloidal mo...
