In this paper the characteristics of unsteady three-dimensional incompressible flows with heat transfer are obtained along with artificial compressibility of Chorin. At first, compatibility equations and pseudo characteristics for three-dimensional flows are derived from five governing equations (continuity equation, Momentum equations in three directions, and energy equation) and then results ...

‎Radial basis functions (RBFs) are a powerful tool for approximating the solution of high-dimensional problems‎. ‎They are often referred to as a meshfree method and can be spectrally accurate‎. ‎In this paper, we analyze a new stable method for evaluating Gaussian radial basis function interpolants based on the eigenfunction expansion‎. ‎We develop our approach in two-dimensional spaces for so...

in this paper, we introduce a takagi-sugeno (ts) fuzzy model which is derived from a typical multi-layer perceptron neural network (mlp nn). at first, it is shown that the considered mlp nn can be interpreted as a variety of ts fuzzy model. it is discussed that the utilized membership function (mf) in such ts fuzzy model, despite its flexible structure, has some major restrictions. after modify...

in this paper, to analyze the transport of autonomous robots, an artificial capital market is used. capital market is considered as a pier which loading and unloading of cargo is done. autonomous robots load and unload from the ship to the warehouse wharf or vice versa. all the robots have the ability of transporting the loads, but depending on loads and the location of unloading (or loading) a...

data envelopment analysis operates as a tool for appraising the relative efficiency of a set of homogenous decision making units. this methodology is applied widely in different contexts. regarding to its logic, dea allows each dmu to take its optimal weight in comparison with other dmus while a similar condition is considered for other units. this feature is a bilabial characteristic which opt...

nowadays, groundwater resources play a vital role as a source of drinking water in arid and semiarid regions and forecasting of pollutants content in these resources is very important. therefore, this study aimed to compare two soft computing methods for modeling cd, pb and zn concentration in groundwater resources of asadabad plain, western iran. the relative accuracy of several soft computing...

Conventional magneto-static finite element (FE) analysis of electrical machine design is time-consuming and computationally expensive. Since each topology has a distinct set parameters, optimization commonly performed independently. This article presents novel method for predicting key performance indicators (KPIs) differently parameterized topologies at the same time by mapping high-dimensiona...

Browsing, which usually alternates with search in information seeking on the web, highly depends on information organization of the browsed web site. An emerging web content categorization is multi-faceted, which does not impose any rigid structure, and allows users to slice and dice the information space from any chosen “dimensions” they wish to browse. However, owing to the limited capacity o...

High dimensional data visualization is very important in data analysts since it gives a direct and natural view of data. In this paper, we propose a method to visualize large amount of high dimensional data in a 3-D space. In our method, we divide the high dimension data into several groups of lower dimensional data first. Then, we use different icons to represent different groups. Initial expe...

In this paper, we present an alternative approach to multiple inheritance for typed feature structures. In our approach, a feature structure can be associated with several types coming from di erent hierarchies (dimensions). In case of multiple inheritance, a type has supertypes from di erent hierarchies. We contrast this approach with approaches based on a single type hierarchy where a feature...
