In this paper simple quartic trigonometric polynomial blending functions, with a tensionparameter, are presented. These type of functions are useful for constructing trigonometricB´ezier curves and surfaces, they can be applied to construct continuous shape preservinginterpolation spline curves with shape parameters. To better visualize objects and graphics atension parameter is included. In th...

We propose a new method to visualize and detect shape outliers in samples of curves. In functional data analysis, we observe curves defined over a given real interval and shape outliers may be defined as those curves that exhibit a different shape from the rest of the sample. Whereas magnitude outliers, that is, curves that lie outside the range of the majority of the data, are in general easy ...

This study provides an empirical analysis of the injury severity outcomes maritime accidents by exploring influential factors for two underlying states: injury-free state and injury-prone state. The former may reflect generation mechanism with limited potential to result in outcomes, whereas, latter represent when accident falls into category. To account possible presence these regimes, a zero-...

This paper describes and applies a new algorithm for decomposing pitch curves into component curves, in accordance with the General Superpositional Model of Intonation. According to this model, which is a generalization of the Fujisaki model [3], a pitch contour can be described as the sum of component curves that are each associated with different phonological levels, including the phrase, foo...

Traditionally schematized maps make extensive use of curves. However, automated methods for schematization are mostly restricted to straight lines. We present a generic framework for topology-preserving curved schematization that allows a choice of quality measures and curve types. Our fully-automated approach does not need critical points or salient features. We illustrate our framework with B...

various scaling methods such as relative viscosity, peclet and reynolds scaling were used to find the best scaling law. scaling and modeling of the flow curves of various model emulsions consist of tragacanth gum (tg) (0.5, 1 % wt), oleic acid (5, 10% v/v) and wpi (2, 4 % wt) were investigated and the best models were selected. as these emulsions are non-newtonian, they do not obey the usual, si...

This study aims to accurately estimate the emissions of seven air pollutants (NOX, SOX, CO2, CO, PM2.5, PM10, and NMVOC) from ships for one year (2020) in busiest port Korea, Busan Port. To achieve this, a more detailed method calculating was developed, taking into account factors such as type fuel used, mode operation, engine output each ship that entered left port. In cases where information ...
