This research develops a weighted evolving fuzzy neural network for PCB sales forecasting and it includes four major steps: first of all, collecting 15 factors among macroeconomic data, downstream production demand and total industrial production outputs and then using the Grey Relation Analysis (GRA) to select a combination of key factors which have the greatest influence on PCB sales. Secondl...

In this paper, an anisotropic nonlinear diffusion equation for image restoration is presented. The model has two terms: the diffusion and the forcing term. The balance between these terms is made in a selective way, in which boundary points and interior points of the objects that make up the image are treated differently. The optimal smoothing time concept, which allows for finding the ideal st...

Hand-drawn pictures differ from ordinary perspective images in that the entire scene is composed of local feature regions each of which is projected individually as seen from its own vista point. This type of projection, called nonperspective projection, has served as one of the common media for our visual communication while its automatic generation process still needs more research. This pape...

A new method of incorporating local image characteristics into blind image restoration is proposed. The local variance of the degraded image is used as a measure of spatial activity, from which individual pixel bounds are determined. A parameter de ned by the user controls the degree of smoothing. The local bounds de ne the solution more precisely than smoothness constraints on the image (inclu...

This paper proposes an algorithm that can improve performance by searching for tone mapping optimized for three types of images through image analysis while maintaining a tone mapping shape based on human visual characteristics. The algorithm uses the optimized Retinex-based color restoration technique by analyzing three types of images based on luminance: highand low-luminance images and image...

Pre-processing such as ltering data in order to remove or at least reduce noise is a crucial step because information which is lost during this ltering cannot be recovered in subsequent steps. It is a well-known fact, that linear ltering does not only reduce noise, but may also lead to a loss of information due to the global smoothing, regardless of structures in the data. In order to overcome ...

An ultra wideband common-mode filter based on coupling multiple resonance points is proposed in the letter. The resonant are realized by four compact defected ground structure (DGS) cells, of which both ends C-type DGS cells and middle H-type cells. size these units different, leads to their different points. Because close distance between inductors generated them, can be used for smoothing fil...

extended interaction oscillators (eio) are vacuum electronic sources of microwave, millimeter-wave and terahertz radiations. in this paper, eio is investigated by using a circuit model. the value of the coupling element in the model is evaluated from the near band-edge dispersion characteristics of the rf structure. the end external loading of the interaction structure is equivalently modeled b...

This paper presents the design, construction and testing of a new capacitive tactile sensor for measurement of normal tactile force. The operation of proposed sensor has been investigated in ASTABLE and MONOSTABLE circuits. According to the results of these circuits the deviation of ASTABLE circuit results is less than MONOSTABLE circuit results. In addition, the results obtained from ASTABLE c...

The present research reviews two basic approaches for the separation circuit configuration analysis. The first approach is to optimize the circuit configuration. In this method, after a circuit modeling, a variety of search algorithms and mathematical optimization methods are used. Previous works show that this approach has more application in the flotation process. The second approach called t...
