E-mail: [email protected] This study gives an overview of spline interpolation, a special class of interpolation methods. The focal concern discussed in this paper is that the augmentation of non-equidistant time series (using averages, previous values, or interpolation) often leads to misleading or erroneous conclusions, as the augmented time series may have different characteristics than the ...

This article presents a comparison of different interpolation techniques both in the spatial and frequency domains. Various methods are presented, from a very simple linear interpolation to more complex cubic convolution. The Fourier analysis is used to compare the methods in the frequency domain. Methods are compared by doubling the images in both spatial directions and calculating the signal-...

Battery electric vehicles (BEVs) are one of the most promising new energy models for industrialization and marketization at this stage, which is an important way to solve current urban haze air pollution, high fuel cost sustainable development automobile industry. This paper takes pure buses as research object relies on operation information management platform in Nantong city propose bus cycle...

As being an essential tool for estimating spatial continuous data, interpolation methods have been applied to various disciplines concerned with the Earth’s surface. In the paper, six spatial interpolation algorithms, including an internationally popular ANUDEM method and five other commonly used interpolation methods, were applied in three different landform regions, that is, hills, mountains ...

The reference to ethnicity in the 2012 National Suicide Prevention Strategy for England (1) is mainly with regard to promoting mental health in Black and Minority Ethnic (BME) groups. However, there is little detailed information about any specific strategy to reduce suicide rates in BME groups. The Suicide Prevention Strategy and Action Plan for Northern Ireland has only one brief reference re...

Abstract: Soil pH has a major effect on plant nutrient availability by controlling the chemical structure of the nutrient. Adjusting soil acidity or alkalinity improves soil nutrition without adding extra fertilizers. Soil nutrients needed by plants in the largest amount are referred to as macronutrients. In addition to macronutrients, plants also need trace nutrients and both macro and trace n...

The MLPG method is the general basis for several variations of meshless methods presented in recent literature. The interrelation of the various meshless approaches is presented in this paper. Several variations of the meshless interpolation schemes are reviewed also. Recent developments and applications of the MLPG methods are surveyed.
