Stochastic Petri nets have been extended for the modelling of hybrid systems by adding uid places, that are lled and emptied continuously at random (normally distributed) rate. The ow rates as well as the discrete transition rates may depend on the content a uid place holds. The dynamics of the model are described by second order partial diierential equations, that can be solved by using an imp...

(La and Ga)-doped tin monoxide [stannous oxide, (II) SnO] thin films were grown by plasma-assisted suboxide molecular beam epitaxy with dopant concentrations ranging from ≈ 5 × 10 18 to 2 21 cm −3 . In this concentration range, the incorporation of Ga into SnO was limited formation secondary phases observed at 1.2 Ga, while La showed a lower solubility limit. Transport measurements on doped sam...

This paper brie®y reviews some recent work demonstrating the partial breakdown of the colloidal ®uid $ atomic ®uid analogy. The success of liquid state theory for atomic ®uids stems in part from the van der Waals picture, where steric interactions dominate the structure, and attractive interactions can be added as a perturbation. For complex ®uids described by e¬ective potentials, this picture ...

Swimming of microorganisms is studied from a viewpoint of extended objects (strings and membranes) swimming in the incompressible uid of low Reynolds number. The agellated motion is analyzed in two dimensional uid, by using the method developed in the ciliated motion with the Joukowski transformation. Discussion is given on the conserved charges and the algebra which are associated with the are...

This paper o ers a new fast algorithm for non-rigid Viscous Fluid Registration of medical images that is at least an order of magnitude faster than the previous method by Christensen et al. [4]. The core algorithm in the uid registration method is based on a linear elastic deformation of the velocity eld of the uid. Using the linearity of this deformation we derive a convolution lter which we u...

In this paper we introduce a new class of stochastic Petri nets in which one or more places can hold uid rather than discrete tokens. We deene a class of uid stochastic Petri nets in such a way that the discrete and continuous portions may aaect each other. Following this deenition we provide equations for their transient and steady-state behavior. We present several examples showing the utilit...

This study was designed to investigate the clinico-haemato-biochemical, rumen fl uid and peritoneal fl uid alteration in buffaloes with peritonitis. Buffaloes with peritonitis had anorexia, dehydration, abdominal distension, ruminal atony, pain, fever, reduced milk yield and loss of defecation. Pungent smelling peritoneal fl uid was yielded on abdominocentesis. Hemato-biochemical alterations re...

Internal boundaries and interfaces are an important part of many uid and solid modeling problems. Front Tracking contains a general interface framework, closely related to the non-manifold geometry used in CAD solid modeling packages, to support numerical simulation of such uid problems. It can thus be considered to be a systematic application of the ideas of computational geometry to computati...

In this paper, we present a mode superposition method for uid-structure interaction problems based on velocity potential and pressure formulation for acoustic uids and displacement formulation for solids. The eeectiveness of the proposed numerical procedure is demonstrated in a test example with seismic ground motion eeects. 1 INTRODUCTION Fluid-structure interaction systems are widely used in ...

Motion of uid elements can be described by the Navier-Stokes equations. They arise from use Law motion to a uid. In this investigation, two dimensional have been engaged. Then they are applied an incompressible viscous movement down inclined plane with net ow. These leads examining effects velocity at various angles inclination and finding boundary layer thickness. Viscous laminar fluid ow also...
