The relationship between inflation and relative price variability (RPV) is widely believed to be positive and stable. Using disaggregated CPI data for the U.S. and Japan, however, this study finds that the relationship is neither linear nor stable over time. The overall relationship is approximately U-shaped and symmetric around a certain threshold: a positive correlation on one side but a trad...

Statistical shape analysis is a field for which there is growing demand. One of the major drivers for this growth is the number of practical applications which can use statistical shape analysis to provide useful insight. An example of one of these practical applications is investigating and comparing facial shapes. An ever improving suite of digital imaging technology can capture data on the t...

The choice of 3D shape representation for anatomical structures determines the effectiveness with which segmentation, visualization, deformation, and shape statistics are performed. Medial axis-based shape representations have attracted considerable attention due to their inherent ability to encode information about the natural geometry of parts of the anatomy. In this paper, we propose a novel...

The renewable energy sources such as wind energy maintain to increase in popularity since they are inexhaustible and pollution-free. The horizontalaxis wind turbine has been the most common type of wind turbines but due to recent increase in popularity of personal green energy solutions, Vertical-Axis Wind Turbines (VAWT) are becoming more common. Besides two mayor rotor types of VAWTs the Darr...

Purpose – Despite many technically sophisticated solutions, managing information security has remained a persistent challenge for organizations. Emerging IT/ICT media have posed new security challenges to business information and information assets. It is felt that technical solutions alone are not sufficient to address the information security challenge. It has been argued that organizations a...

Recent shape editing techniques, especially for man-made models, have gradually shifted focus from maintaining local, low-level geometric features to preserving structural, high-level characteristics like symmetry and parallelism. Such new editing goals typically require a pre-processing shape analysis step to enable subsequent shape editing. Observing that most editing of shapes involves manip...

Nanofluids are new heat transfer fluids, which improve thermal performance while reducing the size of systems. In this study, the numerical domain as a three-dimensional copper mini tube was simulated to study the characteristics of flow and heat transfer of CuO/H2O nanofluid, flowed horizontally within it. The selected model for this study was a two-phase mixture model. The results ...

in this paper, analysis of fluid flow and heat transfer over the bank of tubes is considered. k-ω sst model is applied for simulation of turbulent flow. in this paper, the improvement of efficiency of a bundle of circular tubes by changing the shape of the cross section of one row of the pipes to the elliptical cross section as an innovative plan is considered. as know, friction factor in turbu...

Active shape model (ASM) statistically represents a shape by a set of well-defined landmark points and models object variations using principal component analysis (PCA). However, the extracted shape contour modeled by PCA is still unsmooth when the shape has a large variation compared with the mean shape. In this paper, we propose a regularized ASM (R-ASM) model for shape alignment. During trai...
