In this paper, we construct a truth conditional semantics for generic sentences, which treats arbitrarily deep nestings of generic sentences. The resulting notion of logical entailment captures intuitively valid argument forms involving generics. A dynamic semantics is built on top of the truth conditional one, and the resulting inference notion captures nonmonotonic argument patterns familiar ...

Ear biometric for identification of human is quite complex task. It’s use either uni-modal or multi-modal approach in order to authenticate a person. A uni-modal biometric system involves a single source of biometric to identify a person. This paper is based on uni-modal approach with ear as a biometric trait for recognizing a person. In this paper, an experimental approach is used for identify...

Modal verbs in English are challenging to learn by speakers of other languages. The purpose of thiswas to shed light on the use of gesture in learning English modal verbs by Persian-speaking children.To achieve this, 60 elementary Iranian learners, studying at some institutes in Karaj took part in thisstudy. The participants were randomly put into one experimental group and one control group. T...

Though Blind Source Separation (BSS) techniques have typically been applied within Operational Modal Analysis (OMA) framework, there joint diagonalization property can also be utilized within traditional input-output Experimental Modal Analysis (EMA) for the purpose of modal parameter estimation. This paper explores this possibility and suggests an approach to achieve the same. The paper presen...

In this paper, the cost function for a three-echelon inventory system with two warehouses is derived. Transportation times are constant and retailers face independent Poisson demand. Replenishments are one-for-one. The lead time of a retailer is determined not only by the constant transportation time but also by the random delay incurred due to the availability of stock at the warehouses. We co...

Separation of monaural linear mixtures of ‘white’ source signals is fundamentally ill-posed. In some situations it is not possible to find the mixing coefficients for the full ‘blind’ problem. If the mixing coefficients are known, the structure of the source prior distribution determines the source reconstruction error. If the prior is strongly multi-modal source reconstruction is possible with...

petrography, modal analysis of sandstones and major elements geochemistry of shales of early cambrian zagun formation in sarbandan section, central alborz, are used to identify their provenance (including parent rocks, tectonic setting and paleo-weathering). petrography of the sandstones and plotting their point counting data on qt44, f47, l9 and qm44, f45 ,lt11 diagrams imply that they are ark...
