We look after the generalized inverses of power means in the family of Gini means and in the family of extended means.
Crossed ladders and power means∗
"... Given to positive numbers a and b, we show how we easily can construct the power mean Pk(a, b) of order k for the cases k = −2, −1, −1/2, 0, 1/2, 1 and 2. This is done by observing that the power means correspond to certain distances in the crossed ladders problem. The socalled crossed ladders pro ..."

PowerAware Routing in Mobile Ad Hoc Networks
, 1998
"... In this paper we present a case for using new poweraware metrics for determining routes in wireless ad hoc networks. We present five different metrics based on battery power consumption at nodes. We show that using these metrics in a shortestcost routing algorithm reduces the cost/packet of rout ..."

"... ABSTRACT. In a very interesting and recent note, TungPo Lin [I] obtained the least value q and the greatest value p such that M <L<M P q is valid for all distinct positive numbers x and y where M (x +.y.)s and L s 2 In xln Y The object of this paper is to give a simpler proof than Lin’s of a ..."

ABSTRACT. In a very interesting and recent note, TungPo Lin [I] obtained the least value q and the greatest value p such that M <L<M P q is valid for all distinct positive numbers x and y where M (x +.y.)s and L s 2 In xln Y The object of this paper is to give a simpler proof than Lin’s of a more general result. More precisely, the author obtained the classes of functions f and ha, agR such that In f (t) ha (t) [tl / + I]> O, t> I.
Measurement and Analysis of Online Social Networks

A simple distributed autonomous power control algorithm and its convergence
 IEEE TRANSACTIONS ON VEHICULAR TECHNOLOGY

"... For wireless cellular communication systems, one seeks a simple effective means of power control of signals associated with randomly dispersed users that are reusing a single channel in different cells. By effecting the lowest interference environment, in meeting a required minimum signaltointerf ..."

Panel Cointegration; Asymptotic and Finite Sample Properties of Pooled Time Series Tests, With an Application to the PPP Hypothesis; New Results. Working paper
, 1997
"... We examine properties of residualbased tests for the null of no cointegration for dynamic panels in which both the shortrun dynamics and the longrun slope coefficients are permitted to be heterogeneous across individual members of the panel+ The tests also allow for individual heterogeneous fixed ..."

Corporate Ownership Around The World
, 1998
"... We present data on ownership structures of large corporations in 27 wealthy economies, making an effort to identify the ultimate controlling shareholders of these firms. We find that, except in economies with very good shareholder protection, relatively few of these firms are widely held, in contras ..."

, in contrast to the Berle and Means image of ownership of the modern corporation. Rather, these firms are typically controlled by families or the State. Equity control by financial institutions or other widely held corporations is far less common. The controlling shareholders typically have power over firms
A review of image denoising algorithms, with a new one
 SIMUL

"... The search for efficient image denoising methods is still a valid challenge at the crossing of functional analysis and statistics. In spite of the sophistication of the recently proposed methods, most algorithms have not yet attained a desirable level of applicability. All show an outstanding perf ..."
