Investigation on the effect of stent in unsteady blood flow

  In this work, we tried to determine the fact that an interest in optimal stents shapes helps to minimize fluid swirl and to maximize shear stress on the wall artery in order to reduce the risk of the restenosis in stented segments. Our study deals with three geometric parameters of the stent, namely the strut spacing, the strut height and the strut width. These parameters have direct effect on blood...

Thermal deflection of a thin circular plate with radiation

  This paper deals with the determination of thermal deflection of a thin circular plate defined as ;. A circular plate is considered having arbitrary initial temperature and subjected to radiation type boundary condition which is fixed at . The non homogeneous type boundary conditions are maintained at plane surfaces of the plate. The governing heat conduction equation has been solved by using...

Application of Bousinesq’s and Westergaard’s formulae in analysing foundation stress distribution for a failed telecommunication mast

  The concurrent foundation failure of telecommunication masts in Nigeria and all over the world which endanger the lives and properties of residents situated within the fall distance of the telecommunication mast is a thing of great concern. In this study, a GSM mast that underwent foundation failure at Ibadan, Oyo State, Nigeria was critically examined with a view to providing engineering solution. The soil...

Utilization of mixture of andin imputation for missing data in post-stratification

  To estimate the population mean using auxiliary variable there are many estimators available in literature like-ratio, product, regression, dual-to-ratio estimator and so on. Suppose that all the information of the main variable is present in the sample but only a part of data of the auxiliary variable is available. Then, in this case none of the aforementioned estimators could be used. This paper presents an...
