 Measurement Measurement is the assignment of numbers to objects in such a way that physical relationships and operations among the objects correspond to arithmetic relationships and operations among the numbers. Different levels of measurement are defined by the number and kind of correspondences that hold between the physical relations among objects and the arithmetic relations among the scores. The different levels of measurement are distinguished by which arithmetic operations on the measured scores have counterparts in physical operations on the objects. www.analytictech.com /mb313/measurem.htm   (1792 words)

 NDE Associates, Inc. - Boiler Tube ID Oxide Scale: Measurement and RLA The thickest scale may be expected on tubes that are in the hottest sections of the boiler. Oxide scale measurements should be performed at circumferential locations which are expected to have experienced the highest temperature.

 NWEA | The Measurement Scale NWEA assessments use a measurement scale that has proven to be exceptionally stable and valid over time. Like using a ruler to measure a child's growth in height, we use the RIT scale to measure a student’s academic growth over time. Like meters or pounds, the scale is equal-interval, meaning that the distance between 170 and 182 is the same as the distance between 240 and 252. www.nwea.org /assessments/scale.asp   (501 words)

 Book: Scale Development - Theory and Applications   (Site not responding. Last check: 2007-10-07) Measurement -- the way researchers quantify the observations they have made about people, objects, events, or even processes -- is a fundamental activity of science. One of the main frustrations researchers have experienced in measurement is the lack of an appropriate instrument for their particular research study. Written at an accessible level, Scale Development guides the reader toward the identification of the latent variable, the generation of an item pool, the format for measurement, and the optimization of the scale length. www.assess.com /Books/b-3775X.htm   (155 words)

Last check: 2007-10-07) Photogrametry is a method to determine the spatial distribution of microstrains at the sample surface by measurement of changes in the three dimensional plastic displacement field during a deformation experiment [1, 8]. In order to measure the three dimensional surface coordinates digital stereo pair images of the sample were acquired using two high resolution CCD cameras as shown in Fig. The resulting gray scale pattern on the surface of the specimen was recorded and reference coordinates for the different experimental methods (microtexture, metallography, microstrain determination) were fixed on the sample surface. www2.mpie-duesseldorf.mpg.de /msu-web/msuweb_neu/deutsch/themenkatalog/gsmeasur/project.htm   (3473 words)

 DOE SCiDAC Proposal : Bandwidth estimation: measurement methodologies and applications - CAIDA : PROJECTS : bwest   (Site not responding. Last check: 2007-10-07) As an example, a possible way to measure path capacity is to blast the path with a continuous stream of UDP packets that will gradually eliminate the congestion-responsive TCP traffic from the link, and measure (by consuming) the maximum possible throughput. Paxson observed that the distribution of bandwidth measurements is multimodal, and he elaborated on the identification and final selection of a capacity estimate from these modes [21]. Better bandwidth measurement algorithms are needed by a large class of network applications, traffic engineers controlling path selection and service class differentiation, and users wanting to verify they are receiving the access bandwidth they expect. www.caida.org /projects/bwest/proposal.xml   (5873 words)

 Genome Biology | Full text | Genomic-scale measurement of mRNA turnover and the mechanisms of action of the anti-cancer ... By measuring mRNA turnover rates comprehensively, we identified unexpected relationships between the function of a gene and its mRNA stability. The adjusted R-squared statistic, which is a measure of correlation between the observed data values and the predicted values from the linear model, shows how well a first-order kinetics model would describe the mRNA degradation rates. First, the mRNA abundance at X h, as measured by the ratio of the array element (Cy5/Cy3) must have decreased by at least twofold. www.genomebiology.com /2001/2/10/research/0041   (5685 words)

 Ancient Egypt Magazine - Vol 3 Issue 3 The standard unit of linear measurement used by carpenters was the ‘royal cubit’, which was based on the length of a man’s forearm. Although these measurements were standardised, ‘royal cubit rods’ have been discovered, as one might expect, with an error of up to plus or minus 2 mm in overall length. The author has found that evidence of measurement can also be seen on other types of furniture where the ‘royal cubit’ or ‘short cubit’ were often used as the initial measure to determine either the length, width or height of a piece of furniture. www.ancientegyptmagazine.com /woodwork16.htm   (1829 words)

 Project 3.1 The thermal properties include thermal diffusivity, thermal conductivity, emissivity and transmissivity, and they may need to be measured on a small scale, as in the case of semiconductors, or in-situ in situations where sample preparation is impractical. For example, the validity of a particular radiation-based thermometry measurement on gas turbine blades can be verified by checking the instrument against a LART instrument in a laboratory simulation of the blade environment. As part of the previous NMS programme, an experiment was developed to demonstrate accurate measurement of thermal diffusivity to 1.5% using photothermal radiometry, the most accurate measurement of this property to date. www.npl.co.uk /thermal/projects/project3-1.html   (834 words)

Last check: 2007-10-07) In order to examine the accuracy of acoustic scale modeling, the experimental results of a 1/10-scale model study performed for acoustical design of a concert hall and those measured in the full-scale hall after the construction are compared. In the scale model study, the impulse responses were measured by the direct method using a spark discharge source and monaural and binaural microphone systems. The binaural impulse responses measured in the model and real hall were convolved with the same sources of a variety of music and presented to the subjects through a transaural reproduction system using two loudspeakers. www.auditory.org /asamtgs/asa96haw/5pAA/5pAA13.html   (244 words)

 4pSP3. Perceived unpleasantness of natural sounds: Ratio-scale measurement and psychoacoustic analysis.   (Site not responding. Last check: 2007-10-07) Paired comparisons of a heterogeneous set of ten natural sounds were collected from 60 listeners in order to determine: (1) if the sensation of unpleasantness is judged consistently across a wide range of acoustic stimuli; and (2) which sound features contribute to that sensation. The judgments conformed with the highly restrictive BTL model [R. Luce, Individual Choice Behavior (Wiley, New York, 1959)], thus justifying ratio-scale representation of perceived unpleasantness. The resulting scale values varied by a factor of 100 (diesel engine versus jackhammer). www.auditory.org /asamtgs/asa97snd/4pSP/4pSP3.html   (144 words)

 FRB Minneapolis Research Archive - Aggregate Returns to Scale: Why Measurement Is Imprecise   (Site not responding. Last check: 2007-10-07) ABSTRACT: The extent to which there are aggregate returns to scale at the level of aggregate production has important implications both for the types of shocks generating business cycles and for optimal policy. However, prior attempts to measure the extent of these returns using instrumental variable techniques have yielded quite imprecise estimates. In this article, we show that the production shocks implied by a range of returns to scale that encompasses both large increasing returns and large decreasing returns are almost identical. minneapolisfed.org /research/qr/qr2332.html   (147 words)
