sensitivity analysis might be considered as one of inevitable steps in modelling since it would help to determine the behaviour of model, which was developed for further application. sensitivity analysis was not paid much attention in studies that have been conducted for modelling the relationship between stream water quality and land cover except machine learning techniques such as artificial ...

In vortex motion fluid moves in curve path and the stream lines are curved. When the fluid flows between curved stream line, the centrifugal forces are setup which is counter balanced by pressure forces acting in the radial direction. The vortex motion has two types of curved motion. The first type called free vortex type, the fluid moves due to its own natural effect but energy is not added to...

The investigation of flow data can be eased by the visualization of topological information about the flow. Especially, when empirical models or numerical results from flow simulation are investigated, often the first step of analysis is to search structural elements, like fixed points, separatrices, etc. The work presented in this paper focuses on the visualization of 3D dynamical systems (com...

The main goal of this assessment is to classify the radwaste stream of the recyclable transmission lines (RTL) at the end of the Z-Pinch plant operation. With the emergence of the new clearance standards, we included both the national and international standards in our analysis and assessed the implications for the RTL waste stream. The 3-D spectral flux was coupled to the ALARA pulsed activati...

Statement of problem on vortical inviscid flow of barotropic and incompressible fluids. Abstract The question what information is necessary for determination of a unique solution of hydrodynamic equations for ideal fluid is investigated. Arbitrary inviscid flows of the barotropic fluid and of incompressible fluid are considered. After integrating hydrodynamic equations, all information on the f...

The accuracy of the Digital Elevation Models (DEMs) interpolated using four different methods was compared in two small watersheds in the Ecuadorian Andes. The interpolation methods compared were Inverse Distance Weighted, radial basis functions, ordinary Kriging, and TOPOGRID. A qualitative comparison was made between the stream network modeled in Arc Hydro and the digitized stream network. Mo...

Background: Embryonal carcinoma (EC) cells derived from germ cell tumors are valuable tools for investigating differentiation and developmental biology processes in vitro. The advantage of the reproducible and rapid expansion of these cell lines provides a useful alternative to embryos for the study of mammalian cell differentiation. During early stages of cell differentiation, the rate of tran...

Marine-based ice streams whose beds deepen inland are thought to be inherently unstable1–3. This instability is of particular concern because significant portions of the marinebased West Antarctic and Greenland ice sheets are losing mass and their retreat could contribute significantly to future sea-level rise4–7. However, the present understanding of icestream stability is limited by observati...

Listeners are thought to be capable of perceiving multiple voices in music. Adopting a perceptual view of musical ‘voice’ that corresponds to the notion of auditory stream, a computational model is developed that splits a musical score (symbolic musical data) into different voices. A single ‘voice’ may consist of more than one synchronous notes that are perceived as belonging to the same audito...

We describe an approach to define contours of 3D vector fields and employ them as an interactive flow visualization tool. Although contours are well-defined and commonly used for surfaces and 3D scalar fields, they have no straightforward extension in vector fields. Our approach is to extract and visualize specific stream lines which show the most similar behavior to contours on surfaces. This ...
