Abstract:
This paper identifies the nature of errors in the Percentage Syllable Articulation (PSA) test for Bangla, as a continuation and extension of a study conducted and published by the authors to determine the effects of Reverberation Time (RT) on Bangla. Errors due to RT 2.0 s are enumerated to derive Percent Error (PE) at initial, medial and final positions of phonemes in syllables, for both vowels and consonants. It is found that consonants are more vulnerable to errors than vowels, as their mean PEs are 37.8% and 27.6% respectively. Relative positions of phonemes in syllables have significant e

Abstract:
We compared the accuracy of three intraocular lens (IOL) calculation formulas in eyes with a shallow anterior chamber depth (ACD) and normal axial length (AXL) and control eyes. We retrospectively reviewed eyes with a shallow ACD (<2.5 mm from the corneal epithelium) with normal AXL (22.5≤AXL<24.0 mm) and controls (3.0≤ACD<3.5 mm and normal AXL). Prediction error (PE) and median absolute error (MedAE) were evaluated with SRK/T, Barrett Universal II (BUII), and Kane formulas after adjusting the mean PE to zero for all patients. Percentages of eyes achieving a PE within 0.25 to 1.00 D,

Abstract:
The determination of size specific dose estimation (SSDE) has been proposed for accurate CT dose assessment. The SSDE introduction has prompted numerous manufacturers and researchers to develop various methodologies that have progressed from manual to automated methods in SSDE determination. Few studies reported on truncation effects with respect to specific size and SSDE determination and CT manufacturers are yet to incorporate truncation correction in their system [1,2].
 This study aimed to evaluate the effects of truncation artifacts on the measurement of effective diameter (Deff) and

The present research is significant because the lifting capacity may be increased by inserting polymer beads into drilling mud instead of high-cost additives.
