Piecewise Linear Representation has been widely used to compress online data which are collected by sensors. However, the current existing methods, including Piecewise Aggregate Approximation and Perceptually Important Points cannot own both advantages of calculation speed and recovery accuracy at the same time. In order to improve the Piecewise Linear Representation performance, this work prop...

evapotranspiration is one of the most important components of the hydrological cycle which is directly influenced by atmospheric conditions. this study investigated annual and seasonal trends in reference evapotranspiration (et0) and its key influencing climatic variables during 1966-2005 at 10 stations in southern iran (with centrality of fars province). first, multivariate regression analysis...

In this paper, the variation of temperature and rainfall at Patna are analysed using simple non-parametric tests. The trends in annual maximum minimum daily temperatures, rainfall, number rainy days a year, average per day ratio to have been examined. Tends total monthly Highest month also determined for every year. data Mann-Kendall test indicated statistically significant changes pattern city.

In a recent paper in this journal, Ken Olum attempts to refute the Doomsday argument by appealing to the self-indication assumption (SIA), the idea that your very existence gives you reason to think that there are many observers. In contrast to earlier refutation attempts that use this strategy, Olum confronts and try to counter some of the objections that have been made against SIA. We argue t...

We discuss dynamics of N = 2 supersymmetric SU(nc) gauge theories with nf quark hypermultiplets. Upon N = 1 perturbation of introducing a finite mass for the adjoint chiral multiplet, we show that the flavor U(nf ) symmetry is dynamically broken to U(r) × U(nf − r), where r ≤ [nf/2] is an integer. This flavor symmetry breaking occurs due to the condensates of magnetic degrees of freedom which a...

The problem of aggregating a set of ordinal rankings of n alternatives has given rise to a number of consensus models. Among the most common of these models are those due to Borda and Kendall, which amount to using average ranks, and the /1 and /2 distance models. A common criticism of these approaches is their use of ordinal rank position numbers directly as the values of being ranked at those...

This research highlights the precipitation trends and presents the results of the study in temporal and spatial scales. Precise predictions of precipitation trends can play imperative part in economic growth of a state. This study examined precipitation inconsistency for 23 stations at the Dongting Lake, China, over a 52-years study phase (1961–2012). Statistical, nonparametric Mann-Kendall (MK...

This paper reviews the theoretical predictions for and the experimental measurements of the anomalous magnetic and electric dipole moments of the tau lepton. In particular, recent analyses of the ee → ττγ process from the L3 and OPAL collaborations are described. The most precise results, from L3, for the anomalous magnetic and electric dipole moments respectively are: aτ = 0.004 ± 0.027 ± 0.02...
