It emphasizes the importance of the cooperation between the Department of National Defence, the National Research Council of Canada, and SCC and concludes with a review of the benefits resulting from a recently created network...

... This paper presents a review and analysis of a number of methods of correcting laboratory strength values to in-situ strengths. Methods presented are (1) utilization of an empirical correction factor, (2) use of an analytical model to extrapolate in-situ strength values from tests on disturbed...

... Effective accreditation of third-party laboratories offering product evaluation and follow-up inspection services requires a prescription of laboratory performance and measures to assure compliance with the prescription. While documenting the established criteria can be considered the major...

... Too often the development of laboratory automation systems has proceeded without adequate specifications or design. It is not unusual to find systems which are orders of magnitude too powerful—or, conversely, grossly inadequate—for the automation tasks required. A typical pitfall involves...

... The development of system specifications and functional and implementation designs for one chemistry system at the National Environmental Research Center in Cincinnati is discussed. Technical details are presented to illustrate the form and context of these three phases of the laboratory...

... A set of guidelines for documenting computerized laboratory systems at the management level is presented. The guidelines detail the various documentation that may be required by companies which utilize financial factors to determine project feasibility. The guidelines are divided into five...

... Our experience in the integration of a computer into the regular daily operation of a conventional, research and development, physical properties laboratory is described— from the conception of the idea through planning, design, implementation, and startup to on-line operation. Development...
