abstractbackground: delivering the radiation dose to the target volume and minimizing the dose to normal tissues are the main objectives in radiotherapy. the aim of our study is to enhance the contrast of the portal image to increase the accuracy of delineation of the organs in the irradiation field.   methods: the software was written based on local enhancement of the pixel values in image mat...

Two commonly used approaches to fill the gaps after objects are removed from digital graphics are: image inpainting and texture synthesis. Both approaches have its advantages and disadvantages. Image inpainting will cause blur, while texture synthesis will lead to loss of linear structures. Criminisi, etc., combined the two approaches to a new algorithm that utilized the advantages of both appr...

This paper describes the design and experimental implementation of a discrete-time fixed-order H∞ controller for a DC motor speed and position control. To provide a model for the DC motor, two system identification techniques are employed. In the first one a model for DC motor speed control is identified in open-loop based on black box modeling whereas in the other one a model for position cont...

Over the last decade, the yeast two-hybrid system has become the tool to use for the identification of protein-protein interactions and recently, even complete interactomes were elucidated by this method. Nevertheless, it is an artificial system that is sensitive to errors resulting in the identification of false-positive and false-negative interactions. In this study, plant MADS box transcript...
