Accurate pronunciation is an important component of language ability and the main outward linguistic sign of whether someone is a native speaker of a language or not. An area of particular difficulty for Persian-speaking learners of English, which may cause 'foreign accent' or misunderstanding in speaking, is placement of stress on multi-syllable words. Game-based pronunciation teaching can be ...

Pricing and advertising are two important marketing strategies in the supply chain management which lead to customer demand’s increase and therefore higher profit for members of supply chains. This paper considers advertising, and pricing decisions simultaneously for a three-level supply chain with one supplier, one manufacturer and one retailer. The amount of market demand is influenced ...

I N the design of block ciphers,’ it is considered a virtue if the encipherment can perform all the (2”)! permutations on n vectors, where n is large enough to prevent the feasibility of applying the usual techniques for cryptanalyzing a substitution code. However, this is an impractical target since such a system would require a key of length log,(2”)! = n . 2”. Thus, one is inclined to weaken...

The purpose of this paper is to examine the role of reputation in the matching of lead underwriters and issuing firms in the straight corporate bond market in Japan. While the existing literature already investigates how the issuing firm chooses its lead underwriter at the time of issue, this paper uses successive issues of straight corporate bonds to examine how the matching of lead underwrite...

a {em roman dominating function} on a graph $g = (v ,e)$ is a function $f : vlongrightarrow {0, 1, 2}$ satisfying the condition that every vertex $v$ for which $f (v) = 0$ is adjacent to at least one vertex $u$ for which $f (u) = 2$. the {em weight} of a roman dominating function is the value $w(f)=sum_{vin v}f(v)$. the roman domination number of a graph $g$, denoted by $gamma_r(g)$, equals the...

This paper describes a method for localizing wearable computer users. To realize applications of wearable computers like a human navigation system, the position of a user is required for location-based services. Many localization methods in indoor environments have been proposed. One of the methods estimates user’s position using IR beacons or visual markers. However, these methods have some pr...

In this paper, we analyze the time (viz., the number of cycles) to reach any given crack size in a fatigue life test using a gamma stochastic process. It is assumed that the time increments are nonstationary but independent for each specimen while the shape parameter of the gamma distribution is a function of the crack length. In addition, using a random effect model, the between-specimen varia...
