web information usability is a new issue, which has attracted many specialists in these days. it has been of great importance regarding the increasing growth of web sites requiring quality monitoring. web quality measurement has intrinsic difficulties and complexities, pushing specialists to devise automatic ways to measure its different aspects, among them usability and accessibility. this stu...

conclusion scout views may be useful in determining dose and image quality in ct scanning; however, it is necessary to first determine the most appropriate scout view for ct scans. background while using the automatic exposure control technique in computed tomography (ct), the scout view determines the radiation dose for the ct scan by taking anatomical morphology into consideration. objectives...

In the greenhouse environment, application of complex event processing (CEP) technology can effectively tackle problem recognition patterns that appeared in conditions. existing research, few scholars have proposed a scheme to integrate complicated scenes within environment with high efficiency, convenience, and low coupling. Therefore, order solve hard fusion based on characteristics greenhous...

introduction: brain computer interface (bci) systems based on movement imagination (mi) are widely used in recent decades. separate feature extraction methods are employed in the mi data sets and classified in virtual reality (vr) environments for real-time applications. methods: this study applied wide variety of features on the recorded data using linear discriminant analysis (lda) classifier...

with quick development of digital images and the availability of imaging tools, massive amounts of images are created. therefore, efficient management and suitable retrieval, especially by computers, is one of themost challenging fields in image processing. automatic image annotation (aia) or refers to attaching words, keywords or comments to an image or to a selected part of it. in this paper,...

the output error of the globoidal cam mechanism can be considered as a relevant indicator ofmechanism performance, because it determines kinematic and dynamical behavior of mechanicaltransmission. based on the differential geometry and the rigid body transformations, themathematical model of surface geometry of the globoidal cam is established. then we present theanalytical expression of the ou...

Abstract. Rolling is a well-established forming process for producing finished or semi-finished products in various industries. Although highly automated, most rolling processes are designed manually by experts based on their knowledge, specialized heuristics and analytical models numerical simulations. This manual design approach does not lead to an optimization accounting multiple objectives....

The cortex is the outermost thin layer of gray matter in the brain geometric measurement of the cortex helps in understanding brain anatomy and function In the quantitative analysis of the cortex from MR images extracting the structure and obtaining a representation for various measurements are key steps While manual segmentation is tedious and labor intensive automatic reliable and e cient seg...
