Since its implementation in 1990 the human development index (HDI), the flagship indicator of multidimensional development, has attracted a great deal of attention and critics in academic, political and media circles. It initiated a new stage in the discussion of appropriate indicators to measure socioeconomic development. Until now, the vast majority of empirical work using the HDI-concept tak...

We propose new positive definite kernels for permutations. First we introduce a weighted version of the Kendall kernel, which allows to weight unequally the contributions of different item pairs in the permutations depending on their ranks. Like the Kendall kernel, we show that the weighted version is invariant to relabeling of items and can be computed efficiently in O(n ln(n)) operations, whe...

The Tibet Plateau of Qinghai supports complex vegetation types that are ecologically fragile and sensitive to climatic factors. Therefore, it is important understand the changes in factors responsible for these maintain ecosystem balance promote sustainable development region. this paper based on annual SPOT/VEG NDVI (Normalized Difference Vegetation Index) data, land use topographic temperatur...

The present study aimed to analyze the long-term trends and variability of rainfall in Upper Blue Nile (UBN) basin Ethiopia using Climate Hazards Group Infrared Precipitation with Stations (CHIRPS-v2) product from 1981 2018. A pixel-based trend analysis was made at annual, seasonal, monthly temporal scales. coefficient variation (CV) applied compute variability. for each pixel were analyzed Man...

Abstract The emission, transport, and deposition of desert dust are influenced by environmental factors evaluated mainly as a function precipitation, air temperature, wind. present study estimates the balance its relationship with for period 1981–2020 in Baja California Sur region, Mexico. Monthly data on wind, emission from situ measurements, reanalysis, satellite numerical parameterization sc...

Some of the contributions of Chandrasekhar to the field of magnetohydrodynamics are highlighted. Particular emphasis is placed on the Chandrasekhar–Kendall functions that allow a decomposition of a vector field into rightand left-handed contributions. Magnetic energy spectra of both contributions are shown for a new set of helically forced simulations at resolutions higher than what has been av...

an array is said to converge to an element u when the ith marginal product converges to u\ an element is said to be infinitely divisible when it possesses a Jfeth root for each fee2. (A) There exists a continuous homomorphism A from the semigroup into the additive semigroup of nonnegative reals, such that A(u) = 0 if and only if u is the neutral element. (B) The set {u':u'\u} of factors of any ...

We study the supersymmetry reach of the Tevatron in channels containing both isolated leptons and identified tau jets. In the most challenging case, where the tau branching ratios of the gauginos dominate, we find that searches for two isolated leptons, one identified tau jet and large amount of missing transverse energy have a much better reach than the classic clean trilepton signature. With ...

Kernel methods provide an attractive framework for aggregating and learning from ranking data, and so understanding the fundamental properties of kernels over permutations is a question of broad interest. We provide a detailed analysis of the Fourier spectra of the standard Kendall and Mallows kernels, and a new class of polynomial-type kernels. We prove that the Kendall kernel has exactly two ...
