In deformable model segmentation, the geometric training process plays a crucial role in providing shape statistical priors and appearance statistics that are used as likelihoods. Also, the geometric training process plays a crucial role in providing shape probability distributions in methods finding significant differences between classes. The quality of the training seriously affects the fina...

Shape description is one of the key parts of image content description for image retrieval. Most of existing shape descriptors are usually either application dependent or non-robust, making them undesirable for generic shape description. In this paper, a generic Fourier descriptor (GFD) is proposed to overcome the drawbacks of existing shape representation techniques. The proposed shape descrip...

in this work, studies of underground gas storage (ugs) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. results showed that di...

In the present study, we sought to determine the predictive value of selective nuclear morphometry (SNM) for patient outcome in renal cell carcinoma (RCC). Tumor samples of 140 renal adenocarcinomas diagnosed and treated with radical nephrectomy and hilar lymphadenectomy between 1970 and 1988 with a minimum follow up of 5 years in all the cases were studied by SNM. The morphometric analysis was...

A laser powder bed fusion (LPBF) strategy was developed for manufacturing small channels with high dimensional accuracy in Inconel 718 structures. Particular attention paid to surface characteristics such as equivalent diameter and shape factor. The inherent quality of external surfaces optimized by a systematic variation the LPBF contour parameters well channel cross-section. mean arithmetic r...

In design of a parallel resonant induction heating system, choosing a proper capacitancefor the resonant circuit is quite important. The capacitance affects the resonant frequency, outputpower, Q-factor, heating efficiency and power factor. In this paper, the role of equivalent seriesresistance (ESR) in the choice of capacitance is significantly recognized. Optimal value of resonancecapacitor i...

Mathematical morphology is difficult to introduce for color images because in the color vector space, minimum and maximum cannot be easily defined. So, the necessary conditions, represented by the complete lattice structure induced by an ordering relation, cannot be accomplished. Instead, we can build a pseudo-morphology based on reduced color ordering. This approach uses geometrical shape inva...

Storm water management models using the kinematic wave (KW) approach require the conversion of a natural watershed to its equivalent rectangular cascading plane. A KW cascading plane is specified by the plane’s area, width and slope. Without on-site calibration, there is no guidance how to translate the irregularity of the natural watershed into a rectangular shape that has equivalent hydrologi...
