Education:
University Massachusetts, BS Civil Engineering, 2001 expected.
Professional Affiliations and Awards:
American Society of Civil Engineers 1998-present
Past Work:
His work is focusing on the development of a second-generation web-based graphical user interface to support field users in the acquisition of 3D coordinate information to support real-time tracking of structural steel components at the job site. The current prototype tracking system relies on 3D CAD models which are pre-built and stored in a project database. These help users at the job site visually identify a part and locate its associated, pre-defined fiducial points in the field; however, significant time is required to set-up, operate and maintain these part model libraries. To speed the process, his work is focusing on developing automated methods to mine steel part information based on existing (CIS/2) data representation standards from a project database, and providing visual advisories (VRML) to field users such that the part and its available fiducial points are quickly identifiable and easily located.
Past Experience:
Mr. Fijol came to NIST in the summer and winter of 1999 where he representing the design essence of a prototype ultra-high vacuum artifact transport system (ATS) in an existing design repository (DR). Specifically designed for the purpose of transporting nanometer-scale dimensional artifacts at pressures near 10-8 Pa, the ATS consists of a transport cart and an ultra-high vacuum (UHV) system. The artifacts are the result of nanomanufacturing efforts to create atom-based dimensional standards for the semiconductor industry. To populate the design repository, we represent engineering geometry, function and associated behavior, as well as taxonomies of generic functions and flows of the transport system. We model geometry with digital photographs and Virtual Reality Markup Language (VRML) images of actual Computer-aided Design (CAD) drawings (using Pro-Engineer), represent function with linked textual descriptions, and capture behavior with mathematical expressions. Through an evolving user interface, this representation serves to capture the more than 50 parts and systems of the ATS in such a way that the information relating to form, function and behavior is accessible and browsable to subsequent designers. A paper version of the repository was developed which incorperated the 3-D modle of the ATS along with subsequent systems and parts. This work was presented by Mr. Fijol at the 2000 ASME design conference, Baltimore, MD.
During the summer of 2000 he continued his work on the DR by populating it with design information from the encasements designed at NIST for the Charters of Freedom Project. The Charters of Freedom project incorperated designing and creating new encasements for the Declaration of Independence, Constitution, and the Bill of Rights. In order to populate the repository, he developed 3-D CAD drawing of the encasement using Pro-Engineer based on 2-D dimensioned design drawings for the Declaration of Independence size encasement. He then incorpeated engineering geometry, function and associated behavior, as well as taxonomies of generic functions and flows of the new encasement into the DR. He is currently working on two internal reports which focus on the development of the new encasements, and the representation of the encasements into the DR.
