in the present paper, the flow and heat transfer of two types of nanofluids, namely, silver-water and silicon dioxide-water, were theoretically analyzed over an isothermal continues stretching sheet. to this purpose, the governing partial differential equations were converted to a set of nonlinear differential equations using similarity transforms and were then analytically solved. it was found...
OBJECTIVE To monitor size and shape changes of bone erosions and changes in BMD in the vicinity of the erosion and in the periarticular trabecular compartment of patients with RA using high-resolution peripheral quantitative CT (HR-pQCT) imaging and to compare an automated three-dimensional (3D) image processing technique with manual measurements of erosion width and depth. METHODS The shape ...
Incremental learning of classi cation rules from data streams with concept drift is considered. We introduce a new algorithm RILL, which induces rules and single instances, uses bottom-up rule generalization based on nearest rules, and performs intensive pruning of the obtained rule set. Its experimental evaluation shows that it achieves better classi cation accuracy and memory usage than the r...
This paper contributes to the theory of substructural logics .that are of interest to categorial grammarians. Combining semantic ideas of Hepple [1990] and Mor-rill [1990], proof-theoretic ideas of Venema [1993b; 1993a] and the theory of equational specifications, a class of resource-preserving logics is defined, for which decidability and completeness theorems are established.
We introduce a new model for rill erosion. We start with a network similar to that in the Discrete Web** and instantiate a dynamics which makes the process highly non-Markovian. The behavior of nodes in the streams is similar to the behavior of Polya urns with time-dependent input. In this paper we use a combination of rigorous arguments and simulation results.
Purpose : Over the seventy years, various soil erosion modeling methods were developed in world with different input requirements and complexity. Some of these models have been applied Sri Lanka covering several regions country at scenarios over past twenty years. Thus, prime objective this study is to compare commonly practiced GIS/ RS based assessment derivation techniques model parameters us...
this study compared diet and regular coca-cola on enamel erosion in cold and room temperatures.seventy five enamel specimens were prepared and divided into 5 equal groups (n=15) as follows: group 1: regular beverage at room temperature, group 2: regular beverage at refri-gerator temperature, group 3: diet beverage at room and group 4: diet beverage at refrige-rator temperature. the specimens we...
