Springs for Vertical Seismographs.

Store Managers – the Seismographs in Shopping Centres Store Managers – the Seismographs in Shopping Centres

Purpose: The aim of this paper is to investigate (1) the link between store managers’ evaluation of how customers assess a shopping centre and their own evaluation of the centre and, based on that, (2) the relevance of store managers in reflecting upon and informing the management and marketing practices of the local shopping centre management. Methodology: A conceptual model is developed based...

A Novel X-Axis Tuning Fork Gyroscope with "8 Vertical Springs-Proofmass" Structure on (111)-Silicon

A novel x-axis tuning fork MEMS gyroscope with “8 vertical springs-proofmass” structure for Coriolis effect detection is presented. Compared with the common single-plane springs, the 8 vertical springs, symmetrically located at the top and bottom sides, more stably suspend the large thick proofmass featuring large capacitance variation and low mechanical noise. A bulkmicromachining technology i...

REPORT ON SOME EXPERIMENTAL LONG-PERIOD SEISMOGRAPHS By RALP~ GILMAN

The unexpected usefulness in research of the Press-Ewing seismograph system (Press, Ewing and Lehner, 1958) has stimulated further efforts to obtain even higher seismograph sensitivity in the period range beyond 100 see. A major difficulty has been in maintaining pendulum stability at long periods. This paper describes a stable long-period seismometer and gives results from several se, ismograp...

Springs and Constraints for 3D Drawing

In this paper we present examples of haptic sculpting mediated by a physical model or constraint. Most current work in haptic drawing and sculpting focuses on interacting with a static model and properly simulating contact forces. Our work proposes dynamic models for the creative process. These are based on physical models, but present physically impossible scenarios which allow new forms of ex...
