The pollution problem arising from the flushing of initial rainwater and wastewater accidents while transporting dangerous goods to source water protection areas needs be solved as soon possible. Therefore, design corresponding environmental measures should considered in engineering stage. It is necessary analyze specific work combination with examples. Under this background, paper first briefl...

Some metaphorical mappings between source and target are obvious and appear in collocation patterns in natural language data. However, other metaphors that structure abstract processes or complex topics are trickier to investigate because the target domain is lexically divorced from the source. Using metaphors for the economy as a case study, this paper introduces new techniques to find metapho...

Abstract : Recently, the authors have proposed a novel approach to Direction−Of−Arrival (DOA) estimation using the $\Hf$ criterion. This article examines the limits of performance of $\Hf$−based direction finding and arrives at a lower bound on the estimation error, analogous to the Cramer−Rao Bound (CRB). Furthermore, the analysis of the $\Hf$−based algorithm's prediction error using one of Ak...

We present a detailed analysis of four of the most widely used radio source-finding packages in radio astronomy, and a program being developed for the Australian Square Kilometer Array Pathfinder telescope. The four packages: SEXTRACTOR, SFIND, IMSAD and SELAVY are shown to produce source catalogues with high completeness and reliability. In this paper we analyse the small fraction (∼1 per cent...

A technique of direction finding is proposed, which can be applied to the magnetic-dipole type source located in the conductive ground. To distinguish a weak ULF source signal from the natural noise a network of multicomponent magnetometers is supposed to be used. The data obtained by the ground-based stations is processed in such a way that a set of partial derivatives of the magnetic perturba...

Using parametric and nonparametric procedures, we identify the apparent source of cost inefficiency in banking. Unexplained inefficiencies of 20 to 25% from earlier studies are reduced to 1 to 5% when, in addition to commonly specified cost function influences, variables reflecting the external business environment and common industry indicators of "productivity" are added. While these same pro...

1 Introduction All modern functional languages use variants of the Hindley/Milner type system. This system is quite exible since it allows values to have more than one type, and it is convenient because types can be derived automatically, making explicit type declarations unnecessary. Most trivial programming errors cause the type-deriver to emit error messages, which are usually easy to unders...

This paper presents a statistically and computationally efficient algorithm for direction finding of a single far field source using a multi-sensor array. The algorithm extracts the azimuth and elevation angles directly from the estimated time delays between the array elements. Hence, it is referred to herein as the Time Delay Direction Finding (TDDF) algorithm. An asymptotic performance analys...

Parfait is a static bug checking tool for C/C++ source code, which is designed to be both scalable and precise. Requirements for this tool were derived from interaction with the Solaris operating system team, where it was required to check millions of lines of code in a time-efficient manner, with minimal noise and a low cost of integration into the build process. This paper gives an overview o...

Tropical diseases affect more than 500 million people, one tenth of the world’s population.1 Malaria, for example, kills more than one million people each year.2 And yet, only about one percent of new drugs treat tropical diseases.3 For diseases prevalent in rich countries, patent incentives and commercial pharmaceutical houses have created health innovation systems that are the envy of the wor...
