Comparative analysis of repeatability and reproducibility of compaction testing (abridged for POMS proceedings)
نویسندگان
چکیده
This article investigates possible alternatives for soil compaction testing to potentially replace the standard testing equipment by examining all the testing methods for reproducibility and repeatability. This study found that coefficients of variation and standard error to the mean produced the best results that fit with previous studies.

Determination of Aciclovir and its Related Substance Guanine in Bulk Drug and Tablet Preparation by Capillary Electrophoresis
Two Capillary Zone electrophoresis (CZE) methods were developed in this study, one using an acidic buffer (sodium citrate pH = 2.5) and the other using a basic buffer (sodium tetraborate pH = 9.8). The two methods were compared on the basis of repeatability and reproducibility of results and the CZE method developed with the basic buffer was then selected for further studies. The method was ful...

متن کاملInvestigation of LiF, Mg and Ti (TLD-100) Reproducibility
LiF, Mg and Ti cubical TLD chips (known as TLD-100) are widely used for dosimetry purposes. The repeatability of TL dosimetry is investigated by exposing them to doses of (81, 162 and 40.5 mGy) with 662keV photons of Cs-137. A group of 40 cubical TLD chips was randomly selected from a batch and the values of Element Correction Coefficient (ECC) were obtained 4 times by irradiating them to doses...

Using data from the Centers for Disease Control (CDC) Proficiency Testing (PT) Surveys, we obtained estimates of repeatability (intralaboratory variability between results on the same material) and reproducibility (interlaboratory variability between results on the same material) for the Technicon SMA 6 (or 12/60) and SMAC 1 (or II) systems used with cresolphthalein complexone methodology to me...
متن کاملA Comparative Analysis of Metadiscourse Markers in the Result and Discussion Sections of Literature and Engineering Research Papers
This study compares metadiscourse markers in result and discussion sections of literature and engineering research papers. To this end, 40 research articles (20 literature and 20 engineering) are selected from two major international journals. Based on Hyland’s (2005) model of metadiscourse, the articles are codified in terms of frequency, percentage, and density of interactive and interactiona...
