Cylindrical microparticle transport and deposition from electrokinetic microflow in a 90 degree bend have been numerically simulated. Under the effect of dielectrohporetic force, gravity and stokes force, it’s found that microparticles with larger size deposit on the lower region of the bend’s outer wall. An exponential curve of deposition efficiency versus the product of stokes number and shap...

We describe 'Active Shape Models' which iteratively adapt to refine estimates of the pose, scale and shape of models of image objects. The method uses flexible models derived from sets of training examples. These models, known as Point Distribution Models, represent objects as sets of labelled points. An initial estimate of the location of the model points in an image is improved by attempting ...

the rational cubic function with three parameters has been extended to rational bi-cubic function to visualize the shape of regular convex surface data. the rational bi-cubic function involves six parameters in each rectangular patch. data dependent constraints are derived on four of these parameters to visualize the shape of convex surface data while other two are free to refine the shape of s...

The Weibull distribution is a very applicable model for the lifetime data. For inference about two Weibull distributions using records, the shape parameters of the distributions are usually considered equal. However, there is not an appropriate method for comparing the shape parameters in the literature. Therefore, comparing the shape parameters of two Weibull distributions is very important. I...

We investigate the use of Robust Estimation in an application requiring the accurate location of the centres of circular objects in an image. A common approach used throughout computer vision for extracting shape information from a data set is to fit a feature model using the Least Squares method. The well known sensitivity of this method to outliers is traditionally accommodated by outlier rej...

background: recently, motile sperm organelle morphology examination (msome) criteria as a new real time tool for evaluation of spermatozoa in intracytoplasmic sperm injection (icsi) cycles has been considered. objective: the aim was to investigate the predictive value of msome in in vitro fertilization (ivf) in comparison to icsi cycles and evaluation of the association between msome parameters...

In this paper, the conventional level set method is extended as an efficient approach for shape optimization. The motion of the dynamic interface is governed by Stokes equations. Although this method is not specifically designed for topology optimization, it can handle topology changes easily. Furthermore, a relatively smooth evolution can be maintained without re-initialization. The cost of th...

assessment of cardiac right‑ventricle functions plays an essential role in diagnosis of arrhythmogenic right ventricular dysplasia (arvd). among clinical tests, cardiac magnetic resonance imaging (mri) is now becoming the most valid imaging technique to diagnose arvd. fatty infiltration of the right ventricular free wall can be visible on cardiac mri. finding right‑ventricle functional paramete...
