ROLE OF MEDIAN CURVES AND SURFACES AND THEIR COMPUTATIONS IN COORDINATE METROLOGY

November 15, 2024
Author(s)
Craig Shakarji, Kexin Yin, Qunfen Qi, Edward Morse, Vijay Srinivasan
This paper explores a novel role for median curves and surfaces in coordinate metrology, and the techniques to compute these curves and surfaces. The role includes the important problem of identifying potential outliers in two- and three-dimensional

Towards Ontologizing a Digital Twin Framework for Manufacturing

September 21, 2023
Author(s)
Milos Drobnjakovic, Guodong Shao, Ana Nikolov, Boonserm Kulvatunyou, Simon P. Frechette, Vijay Srinivasan
This paper presents a timely opportunity to ontologize a digital twin frame-work for manufacturing using recently published international standards and proposes a collaborative research effort to accomplish this task. The ISO/IEC 21838 series of standards

RECENT DEVELOPMENTS IN ONTOLOGY STANDARDS AND THEIR APPLICABILITY TO BIOMANUFACTURING

August 21, 2023
Author(s)
Milos Drobnjakovic, Boonserm Kulvatunyou, Vijay Srinivasan, Simon P. Frechette
ISO and IEC have jointly initiated, and recently issued, a series of standards (the ISO/IEC 21838 series) for top-level ontologies. These standards have been used by industrial consortia to develop and disseminate standards for mid-level ontologies to ease

Current challenges and recent advances on the path towards continuous biomanufacturing

June 21, 2023
Author(s)
Boonserm Kulvatunyou, Milos Drobnjakovic, Nenad Ivezic, Vijay Srinivasan, Roger Hart
Continuous biopharmaceutical manufacturing is currently a field of intense research due to its potential to make the entire production process more optimal for the modern, ever-evolving biopharmaceutical market. Compared to traditional batch manufacturing

A Novel Data Standards Platform using ISO Core Components Technical Specification

August 1, 2021
Author(s)
Nenad Ivezic, Boonserm Kulvatunyou, Elena Jelisic, Hakju Oh, Simon P. Frechette, Vijay Srinivasan
It is generally observed in inter-organizational communication that present-day data exchange standards are too costly and too complex to develop and use. These problems in data exchange are felt keenly by manufacturing industry with its vast supply chains

Recent Industrial Roadmaps to Enable Smart Manufacturing of Biopharmaceuticals

January 29, 2021
Author(s)
Sheng Lin-Gibson, Vijay Srinivasan
Biopharmaceutical manufacturing is an evolving industry with great potential to improve public health, but laden with technical and operational challenges. It has many features that are similar to other smart manufacturing industries, but it also has some

On Practice and Theory of Constructive Composite Geometry and Topology

November 25, 2019
Author(s)
Thomas D. Hedberg Jr., Allison Barnard Feeney, Vijay Srinivasan
This paper synthesizes a theory from industrial best practices codified in recent standards. Recent editions of ASME and ISO standards codify the evolving industrial best practices in defining and modeling the information about products made from fibrous

Constrained Least-Squares Fitting for Tolerancing and Metrology

July 1, 2019
Author(s)
Craig M. Shakarji, Vijay Srinivasan
Recent years have seen a remarkable emergence of a particular type of least-squares fitting, called constrained least-squares fitting, in national and international standards on tolerancing and metrology. Fitting, which is called an association operation
