چکیده
Predicting the propulsive power of ships with high accuracy still remains a challenge. Well established practices in 1978 ITTC Power Prediction method have been questioned such as form factor approach and its determination method. This paper investigates possibility to improve predictions by introduction combined CFD/EFD Method where experimental is replaced double body RANS computations. Following Quality Assurance Procedure proposed ITTC, best practice guideline has derived for CFD based applying systematic variations set-ups. verification validation model scale, full scale speed-power-rpm relations between large number speed trials using factors combination ITTC-57 line numerical friction lines are investigated. It observed that usage improves general no deterioration noted within limits this study. Therefore, EFD expected provide immediate improvements Performance Method.

HPTLC-densitometry method development and validation for simultaneous determination of abacavir, lamivudine and zidovudine in combined dosage form
A simple, accurate and precise HPTLC- densitometry method for the simultaneousdetermination of abacavir, lamivudine and zidovudine in pharmaceutical tablet has beendeveloped. Separation of tablet components was performed on aluminum backed HPTLC plates(silica gel 60 F254 20×20 cm with 0.2 mm thickness, Camag, Muttenz, Switzerland ) usingmethanol : chloroform : acetonitrile (4 : 8 : 3 v/v). Good...

In the real world, a knowledge-based system (KBS) must often accommodate a considerable number of references which support the particular knowledge domain. The size of such a knowledge repository makes its detailed verification challenging and subsequent maintenance onerous. New technology can help improve both the verification and maintenance of these knowledge repositories. To investigate the...
