The New Frontiers in Computational Modeling of Material Structures

February 23, 2016
Author(s)
Vijay Srinivasan, Jarek Rossignac, Vadim Shapiro, William Regli
We are witnessing the emergence of a new paradigm in the modeling of material structures. It stems from the digitization of manufacturing and is fueled by advances in additive manufacturing and material science. This paper strives to provide a critical

Datum Planes Based on a Constrained L1 Norm

December 1, 2015
Author(s)
Craig M. Shakarji, Vijay Srinivasan
This paper has two major goals. First, we present an algorithm for establishing planar datums suitable for a default in tolerancing standards. The algorithm is based on a constrained minimization search based on the L_1 (L1) norm after forming a convex

A Constrained L2 Based Algorithm for Standardized Planar Datum Establishment

November 18, 2015
Author(s)
Craig M. Shakarji, Vijay Srinivasan
For years (decades, in fact) a definition for datum planes has been sought by ASME and ISO standards writers that combines the contacting nature of traditional surface plate mating with a means of balancing rocking conditions when there is a centrally

An improved L1 based algorithm for standardized planar datum establishment

Geometric Interoperability via Queries

May 19, 2014
Author(s)
Vijay Srinivasan
The problem of geometric (model and system) interoperability is a non-trivial generalization of the classical problem of part interchangeability in mechanical assemblies. Interoperability subsumes the challenging problems of geometric model quality

Metrological challenges introduced by new tolerancing standards

February 13, 2014
Author(s)
Ed Morse, Yue Peng, Vijay Srinivasan, Craig M. Shakarji
The recent release of ISO has provided designers with a richer set of specification tools for the size of part features, so that various functional requirements can be captured with greater fidelity [2]. However, these tools also bring new challenges and

Metrological Challenges Introduced by New Tolerancing Standards

July 5, 2013
Author(s)
Ed Morse, Yue Peng, Vijay Srinivasan, Craig M. Shakarji
The recent release of ISO 14405-1 has provided designers with a richer set of specification tools for the size of part features, so that various functional requirements can be captured with greater fidelity. However, these tools also bring new challenges

ASME Journal of Computing and Information Science in Engineering (JCISE)

June 14, 2013
Author(s)
Vijay Srinivasan
For over a decade this journal has supported and advanced the research and applications at the intersection of information science and mechanical engineering. In that process it has established itself as a premier outlet for cutting edge research in the

Size tolerancing revisited: A basic notion and its evolution in standards

May 13, 2013
Author(s)
Vijay Srinivasan, Edward P. Morse
Size is a fundamental descriptor of objects – it allows us to quantify 'how big' objects are, and to compare and classify objects based on this notion. In the world of ISO GPS (Geometrical Product Specification and Verification), size is defined much more

Trust Based Multi-Agent Filtering for Increased Smart Grid Security

October 24, 2011
Author(s)
Ion Matei, Vijay Srinivasan
We address the problem of state estimation of the power system for the Smart Grid.We assume that the monitoring of the electrical grid is done by a network of agents with both computing and communication capabilities. We propose a security mechanism aimed

An Engineer Grapples with Sustainable Manufacturing

April 1, 2011
Author(s)
Vijay Srinivasan
A personal view by the author of how, as a research engineer and manager, first in the private sector and now in government service, he witnessed the emergence of a compelling case for sustainable manufacturing and also gained several important insights
