It uses mathematical functions to characterize the significant mode shapes that can be either a local mode shape of the structural member or a superposition of the global cabinet and the local mode shapes. The significant modes for typical cabinets have been identified from fixed-base finite element analyses. In this paper, modal data from in situ and shake table tests for two different cabinets is used to evaluate not only the validity of finite element analysis results but also the premise for developing Ritz vector approach. A key difference observed in the test data is related to the existence of a global rocking in cabinets that are anchored at the base. A rigid body rocking due to base plate uplift cannot be evaluated from fixed-base finite element models that were used in the development of the Ritz vector approach. Finite element analyses after modifications for incorporating cabinet rocking due to base plate uplifting give results that are close to the test data. Even though the test data and the new analyses show that the significant cabinet mode is different from what has been considered in the past, the basic premise for Ritz vector approach remains unchanged. Minor modifications needed in the Ritz vector approach for incorporating cabinet rocking superimposed with local mode shapes are also presented.}, number={3}, journal={Journal of Structural Engineering (New York, N.Y.)}, author={Rustogi, S.

Observations from finite element analyses are used to study cabinet rocking behavior and to show that accurate representation of the boundary conditions at the cabinet base is essential in the evaluation of correct rocking mode. Simple formulations for evaluating the rocking stiffness are developed by conducting detailed analytical studies for three different types of cabinet mounting arrangements. Availability of these formulations enables incorporation of a cabinet rocking mode in the Ritz vector approach [Nucl. Eng. Des. 190 (1990) 225] for evaluating the cabinet dynamic properties in significant mode and for generating the incabinet response spectra.}, number={2}, journal={NUCLEAR ENGINEERING AND DESIGN}, author={Yang, JF and Rustogi, SK and Gupta, A}, year={2003}, month={Feb}, pages={127–141} } @article{xing_wan_rustogi_singh_2001, title={A Commitment-based approach for business process interoperation}, volume={E84D}, number={10}, journal={IEICE Transactions on Information and Systems}, author={Xing, J. and Wan, F. and Rustogi, S.

Finite element analysis of several typical cabinets shows that only few (often one) modes contribute significantly to the spectral accelerations at critical instrument locations inside the cabinet. In most cases the significant mode is a local mode of the cabinet component like door or back wall on which the instrument is mounted. In some cases it can also be a global cabinet mode or a superposition of the global cabinet and local component modes. Dynamic properties of the significant modes can be calculated using Rayleigh–Ritz method. The engineering effort and computational time taken by the new method is a minute fraction of that by the finite element method.}, number={3}, journal={NUCLEAR ENGINEERING AND DESIGN}, author={Gupta, A and Rustogi, SK and Gupta, AK}, year={1999}, month={Jun}, pages={255–272} } @article{rustogi_singh_1999, title={The bases of effective coordination in decentralized multi-agent systems}, volume={1555}, ISBN={3540657134}, url={https://publons.com/publon/21294531/}, DOI={10.1007/3-540-49057-4_10}, abstractNote={Coordination isa recurring theme in multiagent systems design.We consider the problem of achieving coordination in a system where the agents make autonomous decisions based solely on local knowledge.An open theoretical issue is what goes into achieving effective coordination? There is some folklore about the importance of the knowledge held by the different agents,but the rest of the rich agent landscape has not been explored in depth.The present paper seeks to delineate the different components of an abstract architecture for agents that influence the effectiveness of coordination.Specifically,it proposes that the extent of the choices available to the agents as well as the extent of the knowledge shared by them are both important for understanding coordination in general.These lead to a richer view of coordination that supports a more intuitive set of claims.This paper supports its conceptual conclusions with experimental results based on simulation.}, journal={Lecture Notes in Computer Science}, publisher={Berlin; New York: Springer}, author={Rustogi, S.
