The overshoot phenomenon in step‐and‐shoot IMRT delivery
The control loop in the Varian DMLC system (V4.8) requires approximately 65 msec to monitor and halt the irradiation of a segment, causing an "overshoot" effect: the segment ends on a fractional monitor unit larger than that planned. As a result, the actual MU delivered may differ from that planned. In general, for step-and-shoot treatments, the first segment receives more, the last receives le...
متن کاملRotation, Diffusion, and Overshoot in the Sun: Effects on the Oscillation Frequencies and the Neutrino Flux
We have studied the importance of the combined effects of rotation, diffusion, and convective overshoot on the p-mode oscillation spectrum and the neutrino flux of the standard solar model. To isolate the various physical affects included in the new rotation plus diffusion models we also constructed solar models to test the significance of diffusion and of overshoot by themselves. In previous s...
متن کاملReducing Human Error in Simulation in General Motors
This paper focuses on the steps taken to minimize human error in simulation modeling in General Motors. While errors are costly and undesirable in any field, they are especially harmful in simulation which has been struggling to gain acceptance in the business world for a long time. The solution discussed in this paper can be summarized as “enter the data once and use the best tool for the job.”
متن کاملModelling and Experimental Verification of Step Response Overshoot Removal in Electrothermally-Actuated MEMS Mirrors
Micro-electro-mechanical system (MEMS) mirrors are widely used for optical modulation, attenuation, steering, switching and tracking. In most cases, MEMS mirrors are packaged in air, resulting in overshoot and ringing upon actuation. In this paper, an electrothermal bimorph MEMS mirror that does not generate overshoot in step response, even operating in air, is reported. This is achieved by pro...
متن کاملDial-controlled hash: reducing path oscillation in multipath networks
In a multipath network with a naive traffic partitioning scheme, varied packet loss rates as well as varied delays on multiple paths could seriously reduce TCP bandwidth. We propose a scheme, called dial-controlled hash (DCH), for dynamically partitioning traffic flows across multiple paths. DCH allows for fine-grained load balance, minimizes path oscillation for each traffic flow, and does not...
