Optical assessment of Central Receiver Solar Tower systems should be based on annual simulations due to the high variability of solar radiation throughout the year. The most basic approach is using a discretization of the temporal domain which requires a large number of computationally costly optical simulations. This study proposes an alternative approach based on a discretization of the sky which...
Here we have discuss the network coverage of sensors nodes and proposed th+○8e algorithm for energy efficiency, target tracking and optimization. In WSN network for achieving the high energy efficiency we need to avoid long distance communication. We focus on distributed deployment optimization, With optimized sensor deployment, and while target tracking for the optimize energy consumption we can...
Recent studies have utilizes color, texture, and composition information of images to achieve affective image classification. However, the features related to spatial-frequency domain that were proven to be useful for traditional pattern recognition have not been tested in this field yet. Furthermore, the experiments conducted by previous studies are not internationally-comparable due to the experimental...
This paper presents the investigations of possibility to use a ceramic tile composed of waste sludge from wastewater treatment plant which contained of heavy metals as pathway for the blind. This ceramic tile have been expected to have no any bumpy surface but can be detected by some special cane to detect the tile on the pathway. By this research, we found the Hall effect sensor is suitable to detect...
In this paper, an image compression method based on a novel idea of surface fitting is proposed. An image is divided into sub-images using a quad tree according to the complexity of the image surface, which is a three-dimensional surface when the pixel values are considered as heights (z-values) defined on the x-y plane. Sub-image surfaces are approximated using a radial-basis function network (RBFN),...
