We consider queries which originate from a mobile unit and whose result depends on the location of the user who initiates the query. Examples of such queries arc: find the nearest service provider, what are the traffic conditions on a roUie. We execute such queries based on location-dependent dala involved in their processing. To facilitate location-dependent query processing, we build concept ...

In this work the mathematical model of a spatial pattern in chemical and biological systems is investigated numerically. The proposed model considered as a nonlinear reaction-diffusion equation. A computational approach based on finite difference and RBF-collocation methods is conducted to solve the equation with respect to the appropriate initial and boundary conditions. The ability and robust...

A bimodal distribution of tropical tree cover at intermediate precipitation levels has been presented as evidence of fire-induced bistability. Here we subdivide satellite vegetation data into those from human-unaffected areas and those from regions close to human-cultivated zones. Bimodality is found to be almost absent in the unaffected regions, whereas it is significantly enhanced close to cu...

the present research is aimed at investigating how the politeness of the speakers of urdu is influenced by their relative social status in society. the researcher took politeness theory of brown and levinson (1978, 1987) as a model. to observe politeness of urdu speakers, speech act of apology with different strategies was selected. a discourse completion task (dct) was used as an instrument to...

We consider coupled boundary value problems for second-order symmetric equations on time scales. Existence of eigenvalues of this boundary value problem is proved, numbers of their eigenvalues are calculated, and their relationships are obtained. These results not only unify the existing ones of coupled boundary value problems for second-order symmetric differential equations but also contain m...

Robust gender effect has been reported in Multiple Intelligences (MI)-EFL studies across cultures. Nevertheless, research results vary in effect size, Intelligence type, overall estimation etc. The variance is mainly explained in terms of socio-cultural factors. However, although manifold MI inventories and scales are used in studies, the role of the MI-test type in creating variance has not be...

Habitat selection is an active behavioral process that may vary across spatial and temporal scales. Animals choose an area of primary utilization (i.e., home range) then make decisions focused on resource needs within patches. Dominance may affect the spatial distribution of conspecifics and concomitant habitat selection. Size-dependent social dominance hierarchies have been documented in capti...
