[1] An economical approach to improving predictions of hydrological models produced highly accurate representations of ephemeral and perennial stream networks. Traditional drainage network extraction from digital elevation models (DEMs) often yields inaccurate and inconsistent results because of elevation errors. Topographic wetness index maps calculated from alternative terrain representations...

Behaviour biometric can provide a better alternative for traditional password methods and also for physiological biometrics due to the fact that they are very economical and easy to integrate with existing system. Various approaches have been made towards enhancing and improving the performance of keystroke dynamics system. The aim of writing this paper is to deal with all the possible uncertai...

OBJECTIVE Generic medicines provide a safe and economical medical treatment and are used routinely throughout the world. However, a significant proportion of individuals view generic medicines as less safe, less effective and of lower quality compared with their equivalent branded medicines. This study aimed to investigate the effect of an educational intervention on improving perceptions and p...

Automatic control deals with the development and the implementation of methods leading to automatic decision processes, for the purpose of improving the performance of industrial, biological, socio-economical systems. The basic principle of automatic control is feedback: information on the state of a system is collected (sensors) and actions on a system is exerted (actuators) so as to influence...

Metal-based additive manufacturing processes require a supporting of overhanging part areas during the powder solidification e. g. for improving the heat dissipation to the substrate. Technology users nowadays strive to reduce support areas due to economical aspects, while simultaneously enhancing the process stability by maximizing the support stiffness. For the simplification and acceleration...

Global Software Development (GSD) projects are characterized by the fact that work is distributed throughout many geographically distanced sites. Software engineering activities in such scenarios face various challenges. Although interpersonal communication is crucial if a common understanding with regard to the system under construction is to be achieved, time separation, cultural diversity an...

Data in many real-life engineering and economical problems suffer from inexactness. Herein we assume that we are given some intervals in which the data can simultaneously and independently perturb. We consider a generalized linear fractional programming problem with interval data and present an efficient method for computing the range of optimal values. The method reduces the problem to solving...

A goal of software product lines is the economical assembly of programs in a family of programs. In this paper, we explore how theorems about program properties may be integrated into feature-based development of software product lines. As a case study, we analyze an existing Java/JVM compilation correctness proof for defining, interpreting, compiling, and executing bytecode for the Java langua...

Since the work of André Martinet back in the 60’s [7], the notion of ‘economy’ has been accepted as one of the main principles underlying the organization of phonological inventories (hereafter PI). This principle, also named MUAF (‘Maximal Use of Available Features’) by John Ohala [8], states that PI are organized along a few phonetic dimensions that they tend to maximize in terms of number of...

The purpose of this study is to explore the characteristics of an effective State Interactive Video (ITV) program relating to teacher qualifications and strategies, student research and involvement, organization, economical benefits, and technical support. Evidence from this study suggests that ITV instructors need more organization and preparation than is typically required for face-to-face te...
