This paper presents a sensitivity investigation of the expected busy period for a controllable M/G/1 queueing system by means of a factorial design statistical analysis. We studies the effect of four important factors (parameters) that influence the expected busy period of an M/G/1 system, in which the server operates -policy in his idle period. A 2 4 factorial experimental design is used ...

In order to model the effect of mixture parameters and material properties on the hardened properties of, prestressed self-compacting concrete (SCC), and also to investigate the extensions of the statistical models, a factorial design was employed to identify the relative significance of these primary parameters and their interactions in terms of the mechanical and visco-elastic properties of S...

A chromium electroplating bath with the ability to produce homogenous mist was used to evaluate parameters influencing hexavalent chromium (Cr+6) mist sampling methods. The results of 48 Cr+6mist samples collected using the U.S. National Institute for Occupational Safety and Health method 7600...

Pramipexole is the mostly prescribed drug in patients with Parkinson disease. The incidence of Parkinson disease is related to aging and mostly developed in elderly people with difficulty in swallowing or dysphagia. In the current study we aimed to develop an orally fast disintegrating tablet (ODT) of pramipexole as a preferable alternative in geriatric patients. Hence, the fast disintegration ...

The objective of the current study was to develop and optimize a novel lyophilized liposomal formulation anticancer agent carmustine, or bis-chloroethyl nitrosourea (BCNU) for prolonged release that could overcome dose-dependent side effects improve its bioavailability at site action. optimization done using 32 factorial design approach wherein soya phosphatidylcholine (SPC) cholesterol (CH) as...
