Due to improvements in computational resources, interest has recently increased in using implicit scheme for solving flow equations on 3D unstructured grids. However, most of the implicit schemes produce greater numerical diffusion error than their corresponding explicit schemes. This stems from the fact that in linearizing implicit fluxes, it is conventional to replace the Jacobian matrix in t...

A study using 51 wheat, 56 barley and 34 oat grain samples was conducted to investigate the feasibility of predicting the apparent metabolizable energy (AME) value of these cereals for poultry. Stepwise regression analyses were performed to evaluate the relationship of AME with starch, ether extract (EE), crude fiber (CF), soluble sugar (SS), ash and crude protein (CP) (for wheat and barley gra...

the topic of “trilogical denotations” (al-dalalat al-thalath) appears in avicenna logic system following the development of the discourse on “terms subject” (al-mabahith al-alfad) in his system. it was avicenna, who, for the first time, paid more attention to this subject and was responsible for its extended discussion. among the issues to which he addresses is the one on trilogical denotations...

Research on reasoning in description logics has traditionally focused on the standard inference tasks of (un)satisfiability, subsumption, and instance checking. In recent years, however, there has been a growing interest in so-called non-standard inference services (cf. [1]) which prove useful in the creation, evolution, and utilisation of description logic knowledge bases (KBs). In this paper,...

The paper gives a reenement to a well known and easy-to-prove result of basic ideal theory: If an ideal I is contained in the union of a given nite collection of ideals, with at most two of them not prime, I must be contained in one of them. The proposition, stated in this way, leaves out the special structure of the ring under consideration. We show that the lower bound implicit in the proposi...

One of the most challenging problems in recommender systems based on the collaborative filtering (CF) concept is data sparseness, i.e., limited user preference data is available for making recommendations. Cross-domain collaborative filtering (CDCF) has been studied as an effective mechanism to alleviate data sparseness of one domain using the knowledge about user preferences from other domains...

the current study aimed to define some factors contributing to implicit attitude formation mainly in the social interaction context. an agent-based computer simulation of a society including autonomous agents and an attitude object was used to track the implicit attitude progress towards the object. the society could simulate the autonomic behaviors. we provided a complex adaptive system and ob...
