We report an empirical study of Tehran Price Index (TEPIX). To analyze our data we use various methods like as, rescaled range analysis ($R/S$), modified rescaled range analysis (Lo's method), Detrended Fluctuation Analysis (DFA) and generalized Hu...
Piracy in Somalia had been a threat to international shipping since the beginning of Somalia's civil war in the early 1990s. Since 2005, many international
In the UK, US and elsewhere, school accountability systems increasingly compare schools using value-added measures of school performance derived from pupil scores in high-stakes standardised tests. Rather than naively comparing school average scores,...
Non-destructive testing on metallic turbine blades is a challenging task due to their complex geometry. Vibrational test-ing such as Process Compensated Resonance Testing (PCRT) has shown an efficient approach, which first measures the vibrational re...
Defensive refers to any action, behavior, state, strategy, or mechanism intended to protect or prevent harm, injury, or attack. It typically involves measures or tactics used to guard against …
The homological and homotopical Dehn functions are different ways of measuring the difficulty of filling a closed curve inside a group or a space. The homological Dehn function measures fillings of cycles by chains, while the homotopical Dehn functio...
We introduce floating bodies for convex, not necessarily bounded subsets of $\mathbb{R}^n$. This allows us to define floating functions for convex and log concave functions and log concave measures. We establish the asymptotic behavior of the integra...
We introduce the quasi-hyperbolicity constant of a metric space, a rough isometry invariant that measures how a metric space deviates from being Gromov hyperbolic. This number, for unbounded spaces, lies in the closed interval $[1,2]$. The quasi-hype...
The diameter of a graph measures the maximal distance between any pair of vertices. The diameters of many small-world networks, as well as a variety of other random graph models, grow logarithmically in the number of nodes. In contrast, the worst con...
proud: Feeling pleasurable satisfaction over an act, possession, quality, or relationship by which one measures one's stature or self-worth.
Proud definition: Feeling pleasurable satisfaction over an act, possession, quality, or relationship by which one measures one's stature or self-worth.
Feeling pleasurable satisfaction over an act, possession, quality, or relationship by which one measures one's stature or self-worth: proud of one's child; proud to serve one's country.
The trade of a fixed stock can be regarded as the basic process that measures its momentary price. The stock price is exactly known only at the time of sale when the stock is between traders, that is, only in the case when the owner is unknown. We sh...
We follow the main stocks belonging to the New York Stock Exchange and to Nasdaq from 2003 to 2012, through years of normality and of crisis, and study the dynamics of networks built on two measures expressing relations between those stocks: correlat...
We study the long time behavior of an advection-diffusion equation with a random shear flow which depends on a stationary Ornstein-Uhlenbeck (OU) process in parallel-plate channels enforcing the no-flux boundary conditions. We derive a closed form fo...
May 24, 2023 · The tallest person alive in the world today is Sultan Kösen, who measures 2.51m in height. Kösen, a farmer from Turkey, has held the record for the world’s tallest man since Guinness …
Feb 22, 2026 · We've tested a tremendous number of the best Wi-Fi routers on the market in our custom testing environment, creating an in-depth router benchmarking suite that measures performance in …
In statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures
Analytical, free of time consuming Monte Carlo simulations, framework for credit portfolio systematic risk metrics calculations is presented. Techniques are described that allow calculation of portfolio-level systematic risk measures (standard deviat...
Variable importance is defined as a measure of each regressor's contribution to model fit. Using R^2 as the fit criterion in linear models leads to the Shapley value (LMG) and proportionate value (PMVD) as variable importance measures. Similar measur...
