Probing System Characteristics in Coordinate Metrology
This paper aims at studying the effect of the dynamic errors on surface measurements using three different types of touch trigger probes attached to a bridge-type-CMM. Unforeseeable dynamic root errors of a ductile touch trigger probing system have been characterized theoretically and experimentally as well. The results were employed in validating a developed analytical twodimensional-model (2D...
متن کاملislanding detection methods for microgrids
امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولPoint Laser Triangulation Probe Calibration for Coordinate Metrology
Point Laser Triangulation (PLT) probes have significant advantages over traditional touch probes. These advantages include throughput and no contact force, which motivate use of PLT probes on Coordinate Measuring Machines (CMMs). This document addresses the problem of extrinsic calibration. We present a precise technique for calibrating a PLT probe to a CMM. This new method uses known informati...
متن کاملMultisensor Integration and Discrete Geometry Processing for Coordinate Metrology
Multisensor integration systems are used to fulfill the increasing requirements on the complexity andaccuracy of coordinate metrology. This thesis investigates on the achievement of multisensor integration incoordinate metrology from two main parts: function and data modeling; and discrete geometry processing.Function and data modeling allow obtaining clear understanding of the syst...
متن کاملUnderstanding recruitment: outcomes associated with alternate methods for seed selection in respondent driven sampling
BACKGROUND Respondent driven sampling (RDS) was designed for sampling "hidden" populations and intended as a means of generating unbiased population estimates. Its widespread use has been accompanied by increasing scrutiny as researchers attempt to understand the extent to which the population estimates produced by RDS are, in fact, generalizable to the actual population of interest. In this st...
