The Role Of Quality Assurance In Vehicle Emission Testing
Author(s): Michael J. Mccrystal
Abstract/Introduction:
The strict regulation of vehicle emissions since the 1970 amendments to the Clean Air Act were implemented has led to the development of a complex analytical system and test procedure for determing compliance to State and Federal standards. The complexity of the analytical system and the inter-relationship of the measurement variabilities present special problems in obtaining accurate data. The quality assurance program developed at Chrysler to minimize the systematic errors occurring in the test system and to enhance the reliability of the emission results is described.

The Measurement Of A Laser: The Shiva Project Technical Paper Presentation
Author(s): Donald E. Campbell
Abstract/Introduction:
This paper will discuss the multitude of diagnostic measurements used to determine the details of the fusion process occuring in glass microballoons filled with-a mixture of deuterium and tritium gas ignited by focused laser beams. The entire burning takes place in approximately one nanosecond making necessary very high-speed recording instruments to diagnose these processes in real time. Instruments will be discussed which diagnose X-rays, neutrons, ions, electrons, alpha particles and absorbed and scattered laser radiation. Emphasis will be placed on electronic equipment required to support these measurements. Several diagnostic techniques will be discussed that are still in the planning stage.

The Paradox Of Parochial Calibration
Author(s): D.R. Don Tobey
Abstract/Introduction:
With the advent of sophisticated and complex peculiar Ground Support Equipment (GSE), recent recommendations to the calibration related problems of spiraling cost, proliferation, and divergent support philosophies, have become the subject of voluminous literature. Solutions have ranged from the determination of reliability models and statistically derived calibration recall intervals, to realignment of the overall management and quality control costructs. While some of these suggestions may provide remedial solutions, this paper presents the paradox of redesigning management controls by suggesting that management of metrology concepts be incorporated into the GSE design system itself. To modify a old cliche, the metrology engineer must influence the design of GSE to prevent the traceability problems associated with parochial calibration: TO a large degree, the need for a cure will go away.

Gaseous Emission Measurements On Utility Boiler Systems
Author(s): G.H. Shiomoto, R.R. Pease
Abstract/Introduction:
Emission measurements of all stationary sources has become important in attempting to reduce a growing pollution problem. Utility boilers, one of the largest emission sources, were among the first to be evaluated for emissions and regulated. Regulations have been imposed on the two basic emission groups, particulates and gaseous pollutant species. This paper deals with the measurement of the gaseous species in the boiler flue gases. An extractive, multi-point sampling system, typically used with a mobile emissions monitor, is described. The gaseous species measured include oxygen, carbon dioxide, carbon monoxide, oxides of nitrogen and oxides of sulfur. In addition to emission measurement for inventory or emission reduction tests, these gaseous measurements are useful for improving- boiler efficiency. Continuous ammonia measurement, which may become an important factor in the future, is also described.

The Use Of High Frequency Electromagnetic Radiation To Probe For Economically Producible Hydrocarbons
Abstract/Introduction:
Electromagnetic measurement techniques have been used for many years to investigate the formation surrounding an oil well borehole. Presently d.c. and low frequency radiation are used to differentiate between water bearing and hydrocarbon bearing rocks. Recent results have shown that additional information can be gained by using high frequency radiation techniques. This paper will discuss a microwave technique presently in the field and a proposed radio frequency measurement. Particular attention will be paid to the hardware involved in making the measurements in the 25 - 175C, 138 MPa (20,000 psi) environment of the drill hole.

Measurement Challenges To Developing New Energy Technologies
Author(s): J. W. Moyer, G. K. Crane
Abstract/Introduction:
As we in the advanced electric power generation and distribution field attempt to bring new conversion concepts into commercial utilization, we invariably find new engineering as well as environmental types of measurements which need to be made in order to develop, assess and control these new technologies. Often these measurements must be consistently accurate and reliable, and must be made in hostile environments in which they have never been made before. The paper will discuss briefly a few of the significant measurement challenges which are currently facing us in the development of new energy techologies.

The Use Of Llicroelectronic Test Structures To Characterize Ic Materials, Processes, And Processing Equipment*
Author(s): L. W. Linholm, G. P. Carver, T. J. Russell
Abstract/Introduction:
With the increasing complexity of large scale integrated circuits, it is becoming more difficult to fully characterize circuit performance. Nicroelectronic test structures offer an important source of reliable data for circuit characterization. When properly designed, test structures can be used to evaluate material, process, process equipment, and device parameters to provide the necessary information for circuit characterization. The National Bureau of Standards is conducting a program to develop well-designed test structures and methods to test these structures. The t&t structures are nodular and can be tested with computer-controlled data acquisition systems they can be used to obtain unambiguous information on the parameter the structure is intended to measure. Data from these test structures can be applied to circuit characterization, process control. technology assessment, and yield analysis. Examples of the test structures in some of these applications are presented.

Automated Techniques For Characterizing And Displaying Ic Photomasking Variations
Author(s): F. E. Wahl, T. F. Hasan, S. W. Mylroie, D. S. Perloff
Abstract/Introduction:
The fabrication of complex integrated circuits involves the use of photolithographic and etching techniques for patterning semiconductor wafers. In addition, the features delineated by successive masking steps must be carefully aligned to those introduced in earlier operations. This paper describes a series of automated electrical and optical measurement techniques for evaluating and controlling dimensional variations, etching uniformity, and alignment accuracy across a wafer. Data are collected at 118 uniformly distributed test sites and displayed in the form of easily interpreted two-dimensional maps. This approach provides a comprehensive set of tools for process development, engineering studies and quality control.

Measurement Needs And Techniques For Clinical Chemical Analyzers
Abstract/Introduction:
The clinical Instruments Division of Beckman Instrument produces instruments for use in Hospital and Private Laboratories to measure chemicals in Blood and other body fluids. The measurements made during incoming inspection, production and test of the instruments and associated chemicals and supplies include electrical, mechanical and chemical techniques. In most cases normal measurement instrumentation and techniques are used. In some cases these measurements are traceable toNBS. Probably the most challenging measurement requirements are for our chemical calibrators and controls. In this area we are limited by our instrumentation where we need to determine the value of these products more accurately than the instrumentation is basically capable of. Thus, we must apply exacting statistical analysis along with very controlled measurement techniques to assure the correct value for these calibrators and controls. Some aspects of the problem and how we approach it will be discussed in this paper.
