Middle and southern Iraq suffers from polluted soils due to crude oil, spilled on land, leakage from transmitting pipe networks, or petroleum products from refineries. Many researchers have studied pollution impacts on the soil in details, but there is a clear lack of investigation on the influence of crude oil on soil erodibility. Recent researches have investigated the influence of pollution ...

We propose an efficient new method for estimating scaling factors among probabilistic models in speech recognition. Most speech recognition systems consist of an acoustic and a language model, and require scaling factors to balance probabilities among them. The scaling factors are conventionally optimized in recognition tests. In our proposed method, the scaling factors are regarded as paramete...

This paper describes the yield estimation approach to layout scaling of submicron VLSI circuits. The presented method makes it feasible to find scaling factor of the IC design which is optimal from the manufacturing yield point of view. It allows also to reduce time-consuming extraction of the critical area functions. Examples of yield calculations using the proposed method are presented as well.

We analyze the capacity scaling laws of wireless networks where the spatial distribution of nodes over the network area exhibits a high degree of clustering. In particular we consider the presence of heterogeneous clusters, both in size and in population, which are common in many real systems. We completely characterize the scaling exponent of the resulting network capacity by providing upper a...

Heavy-to-light meson form factors at large recoil can be described using the same techniques as for hard exclusive processes involving only light hadrons. Two competing mechanisms appear in the large-recoil regime, describing so-called “soft-overlap” and “hard-scattering” components of the form factors. It is shown how existing experimental data from B and D decays constrain the relative size o...

In this paper, we present a comparative overview of 9 studies on perceptual quality dimensions of synthetic speech. Different subjective assessment techniques have been used to evaluate the text-to-speech (TTS) stimuli in each of these tests: in a semantic differential, the test participants rate every stimulus on a given set of rating scales, while in a paired comparison test, the subjects rat...

We evaluate factor analysis and multi-dimensional scaling (MDS) as tools for the analysis of voter decisions over a series of dichotomous choices. We simulate binary voting data with a known form and illustrate that standard factor analyses of these types of data yield additional artifactual dimensions. This effect may be exacerbated by the choice of inter-voter measures of similarity used as i...

Scaling is one of the complex operations in Residue Number System (RNS). This operation necessary for RNS-based implementations deep neural networks (DNNs) to prevent overflow. However, state-of-the-art RNS scalers special moduli sets consider 2k modulo as scaling factor, which results a high-precision output with high area and delay. Therefore, low-precision based on multi-moduli factors shoul...

The purpose of this article is to develop a procedure to identify risks in public companies based on cohesion relationships among terms and topic visualization. Prospectuses of public companies in the industry of computer implication services in China were collected and chapters of “risk factors” in those prospectuses were analyzed. Texts were split into 10 categories corresponding to different...
