Errors in Practical Measurement in Science, Engineering, and Technology B. Austin Barry A step-by-step presentation of how random errors occur when taking measurements, how these errors behave, how measurement errors can be used to determine the reliability of the values, and how to accord weights to different measurements of the same quantity. Introduces the concept of percentage compliance with a demand specification, discusses practical plotting of frequency distribution curves, offers tables of areas beneath the normal curve to assist in formulating the validity of measurements, and provides basic information of the probability ellipse for two-dimensional errors. Appendices contain a review and reference of significant figures, complete information for writing a specification for a procedure, suggestions for the use of a Fortran program, and more. 1978 (0 471-03156-9) 183 pp.

The past decade and a half have seen a virtual revolution in equipment and procedures for field and office measurement. Transits have become nearly 100% optical, electronic distance-measuring is now standard, hand-held calculators and microcomputers are increasingly evident, and the use of satellites for positioning ground points will soon be practical. These dramatic developments have prompted this second edition of Construction Measurements. Updated and expanded, Construction Measurements, Second Edition gives you clear, accurate coverage of:

• The new technology of Global Positioning, the positioning of an occupied station on the geoidal surface by means of satellites
• The use of electronic distance measurement
• New procedures such as the use of lasers in construction, " radial surveying," inertial surveying, and others
• Application of calculators, computers and computers software

Construction Measurements, Second Edition continues its comprehensive coverage of traditional topics as well. You'll find chapters on difference of elevation, distance measuring by taping, laying out angles, stakes, and hubs, control marks, shafts and tunnels, offshore measurements, and more. Working appendices provide details on special problems and optics. Invaluable as a reference, review or tutorial, Construction Measurements, Second Edition will serve surveyors, construction contractors, and engineers.
