An Analysis Of Requirements For Specifying Manufacturing Engineering And Business Processes, Steven Ray, Amy Knutilla, Craig Schlenoff Aug 1998

An Analysis Of Requirements For Specifying Manufacturing Engineering And Business Processes, Steven Ray, Amy Knutilla, Craig Schlenoff

Steven R Ray

A wide range of manufacturing software applications deal with the manipulation and expression of collections of activities. Examples include manufacturing process planning, production scheduling, simulation, project management, workflow, business process reengineering, and product realization process modeling. While each of these applications serves a specific audience and need and focuses on particular aspects of a process, much could be gained by sharing process information among applications. One of the primary obstacles to such integration is the lack of any common representation of what is really the underlying concept of process. The objective of the work described here is to investigate the …

Local Mechanical Spectroscopy With Nanometer-Scale Lateral Resolution, Nancy Burnham, F Oulevey, G Gremaud, A Semoroz, Aj Kulik, E Dupas, D Gourdon Apr 1998

Local Mechanical Spectroscopy With Nanometer-Scale Lateral Resolution, Nancy Burnham, F Oulevey, G Gremaud, A Semoroz, Aj Kulik, E Dupas, D Gourdon

Nancy A. Burnham

A new technique has been developed to probe the viscoelastic and anelastic properties of submicron phases of inhomogeneous materials. The measurement gives information related to the internal friction and to the variations of the dynamic modulus of nanometer-sized volumes. It is then the nanoscale equivalent to mechanical spectroscopy, a well-known macroscopic technique for materials studies, also sometimes called dynamic mechanical (thermal) analysis. The technique is based on a scanning force microscope, using the principle of scanning local-acceleration microscopy (SLAM), and allows the sample temperature to be changed. It is called variable-temperature SLAM, abbreviated T-SLAM. According to a recent proposition to …

Friction Anisotropy And Asymmetry Of A Compliant Monolayer Induced By A Small Molecular Tilt, Nancy Burnham, M Liley, D. Gourdon, Dimitrios Stamou, U Meseth, T Fischer, C Lautz, H Stahlberg, H Vogel, C Duschl Apr 1998

Friction Anisotropy And Asymmetry Of A Compliant Monolayer Induced By A Small Molecular Tilt, Nancy Burnham, M Liley, D. Gourdon, Dimitrios Stamou, U Meseth, T Fischer, C Lautz, H Stahlberg, H Vogel, C Duschl

Nancy A. Burnham

Lateral force microscopy in the wearless regime was used to study the friction behavior of a lipid monolayer on mica. In the monolayer, condensed domains with long-range orientational order of the lipid molecules were present. The domains revealed unexpectedly strong friction anisotropies and non-negligible friction asymmetries. The angular dependency of these effects correlated well with the tilt direction of the alkyl chains of the monolayer, as determined by electron diffraction and Brewster angle microscopy. The molecular tilt causing these frictional effects was less than 15 degrees, demonstrating that even small molecular tilts can make a major contribution to friction.

Process Specification Language: An Analysis Of Existing Representations, Amy Knutilla, Stephen Polyak, Craig Schlenoff, Shu Cheah, Steven Ray, Richard Anderson Dec 1997

Process Specification Language: An Analysis Of Existing Representations, Amy Knutilla, Stephen Polyak, Craig Schlenoff, Shu Cheah, Steven Ray, Richard Anderson

Steven R Ray

The goal of the NIST Process Specification Language (PSL) project is to investigate and arrive at a neutral, unifying representation of process information to enable sharing of process data among manufacturing engineering and business applications. This paper focuses on the second phase of the project, the analysis of existing process representations to determine how well existing process representation methodologies support the requirements for specifying processes found in Phase One. This analysis will provide an objective basis from which to develop a comprehensive language and will promote the leveraging of existing work.

Bribery: The Concept, Michael Pritchard Dec 1997

Bribery: The Concept, Michael Pritchard

Michael Pritchard

The aim of this paper is to clarify the concept of bribery, and to do this in a way that reveals its underlying normative features. Bribery, like lying is not a value neutral concept. It has a negative connotation and is regarded by most as generally, although not necessarily universally, wrong. At the very least, those who resort to bribery bear a burden of justification for what they do. This is no small point, as no such burden must be borne for the vast majority of human activities, such as engaging in conversation or taking a walk, which normally …

Professional Responsibility: Focusing On The Exemplary, Michael Pritchard Dec 1997

Professional Responsibility: Focusing On The Exemplary, Michael Pritchard

Michael Pritchard

The literature on ethics in science and engineering tends to dwell on the negative, emphasizing disasters, scandals, and problems of wrongdoing in everyday practice. This paper shifts to the positive, focusing on the exemplary. After outlining different possible conceptions of responsibility (ranging from a minimalist view of “staying out of trouble” to “going above and beyond the call of duty”), the paper discusses the importance of certain virtues for scientists and engineers. Finally, a broad range of examples of exemplary practice is offered.
