Alan L. Dye, a partner at Hogan & Hartson in Washington, who serves on the advisory board of the National Association of Stock Plan Professionals, a trade group, said, "My sense is, based on experience in the market, that there is a softer impact in the market" when an insider uses a trading plan.
The effectiveness of the proposed control scheme is confirmed numerically for the case of a periodically excited, soft impact oscillator.
Meanwhile, for soft/hard and hard/soft cases, the specific aspect of shear instability, which has a very high heat-up rate, is always observed on the relatively soft impact counterpart where a thin molten layer is expected as well.
The finite element method and a dynamic condensation are used to predict first the response of a beam on elastomer or all-metal mounts under hard and soft impact forces, and then the response of a rigid body on elastomer mounts under base excitation.
Results from the tests and simulations showed the existence of a size effect in NSC cylinders under both, hard and soft, impact loading.
Unlike the study on HSC that used soft impact only, this study on NSC used both soft and hard impact.
Based on an energy balance, it aims to predict a perforation limit for different targets under soft impacts.
This article provides an overview of the literature dealing with three types of soft impacts of concern for the aerospace applications, namely impacts of rain drops, hailstones and birds against aircraft.
Soft impacting mechanical systems where the impacting surface is cushioned with a spring damper support are common in engineering.
