We establish new Bombieri-Vinogradov type estimates for a wide class of multiplicative arithmetic functions and derive several applications, including: proof recent estimate by Drappeau Topacogullari arithmetical correlations; theorem Erdős-Wintner with support equal to the level set an additive function at shifted argument; law iterated logarithm distribution prime factors integers weighted $...

Weighted linear prediction (WLP) is a method to compute allpole models of speech by applying temporal weighting of the residual energy. By using short-time energy (STE) as a weighting function, the algorithm over-weight those samples that fit the underlying speech production model well. The current work introduces a modified WLP method, stabilised weighted linear prediction (SWLP) leading alway...

As proposed in various places, a set of propositional formulas, each associated with a numerical weight, can be used to model the preferences of an agent in combinatorial domains. If the range of possible choices can be represented by the set of possible assignments of propositional symbols to truth values, then the utility of an assignment is given by the sum of the weights of the formulas it ...

We study the existence of pure Nash equilibria in congestion games with player-specific costs. Specifically, we provide a thorough characterization of the maximal sets of cost functions that guarantee the existence of a pure Nash equilibrium. For the case that the players are unweighted, we show that it is necessary and sufficient that for every resource and for every pair of players the corres...

Mixed noise expulsion from characteristic images is a testing errand since the noise dispersion normally does not have a parametric model and has an overwhelming tail. One sort of the mixed noise is Additive White Gaussian Noise (AWGN) coupled with Impulse Noise (IN).However, first catch the region of IN pixels and afterward evacuate the mixed noise. On the other hand, such techniques have a te...

The paper compares different approaches to estimate the reliability of individual predictions in regression. We compare the sensitivity-based reliability estimates developed in our previous work with four approaches found in the literature: variance of bagged models, local cross-validation, density estimation, and local modeling. By combining pairs of individual estimates, we compose a combined...

Certainty equivalents (CEs) of gambles are assumed to have a ratio scale representation that is strictly increasing in each consequence and the slalus quo is a singular point. A rankand sign-dependent weighted linear representation arises as follows. Gambles with both gains and losses are reduced to the formally equivalent binary alternative with the CEs of the subgambles of gains and of losses...

In a recent issue of the Journal, VanderWeele and Vansteelandt (Am J Epidemiol. 2011;174(10):1197-1203) discussed an inverse probability weighting method for case-control studies that could be used to estimate an additive interaction effect, referred to as the "relative excess risk due to interaction." In this article, we reinforce the well-known disadvantages of inverse probability weighting a...

We present improvements to the refinement stage of YANGsaf[1] (Yet ANother Glottal source analysis framework), a recently published F0 estimation algorithm by Kawahara et al., for noisy/breathy speech signals. The baseline system, based on time-warping and weighted average of multi-band instantaneous frequency estimates, is still sensitive to additive noise when none of the harmonic provide rel...

Diamond-wire-sawn (DWS) technology has been widely used in the photovoltaic industry. When using HF/HNO 3 /H 2 O acid etching solution for texturing of DWS multi-crystalline silicon(mc-Si), aid additive is required to improve reactivity mc-Si surface solution. It also needs enhance nucleation and uniform growth surface. This paper proposes a non-metallic texturing. Sodium polyacrylate added red...
