In this research, effect of nanoparticles dimeter on free convection of aluminum oxide-water was investigated in a cavity by single phase and two phase models. The range of Rayleigh number is considered 105-107 in volume fractions of 0.01 to 0.03 for nanoparticles with various diameters (25, 33, 50 and 100 nm). Given that the two phase nature of nanofluids, necessity of modeling by this method ...

probabilities (4–7 ), commonly using (stochastic) queuing analysis and nucleation models. These modeling approaches are thoroughly discussed elsewhere (7 ). Here, use is proposed of a coupled set of partial differential equations describing both the traffic dynamics [using the first-order model of Lighthill and Witham (2) and Richards (3)] and the dynamics of the phase-transition probabilities....

This paper provides a new approach for power flow and modeling analysis of three phase unbalanced radial distribution systems (URDS) using the simple forward/backward sweep-based algorithm. A three phase load flow solution is proposed considering voltage regulator and transformer with detailed load modeling, for the transformer modeling symmetrical components theory is used and zero sequence-vo...

we report a three-phase bone scintigraphy for the diagnosis of a peripheral bone lesion caused by systemic sarcoidosis. a 32-year-old man with suspected osteomyelitis of the right forefinger underwent three-phase bone scintigraphy with tc-99m hydroxymethylene diphosphonate (hmdp) and single-photon emission computed tomography/computed tomography (spect/ct). the lesion was rich in blood flow acc...

In this paper, a framework utilizing constructs from category theory for compositional specification of dependable distributed protocols has been proposed. The paper shows how by defining external interfaces of basic modules, and functional mappings linking two different modules, a larger or more complex protocol can be composed and verified. To illustrate the proposed approach, the composition...
