in recent years, demand for biological sensors which are capable of fast and accurate detection of minor amounts of pathogens inreal‑time form has been intensified. acoustic wave (aw) devices whose performance is determined by mass sensitivity parametersand quality factor are used in biological sensors as platforms with high quality. yet, current aw devices are facing many challengessuch as the...

The enormous economic loss caused by power quality problems (more than $150 billion per year in USA) makes power quality monitoring an important component in power grid.With highly connected fragile digital equipment and appliances, Smart Grid has more stringent timeliness and reliability requirements on power quality monitoring. In this work, we propose a change-point detection theory-based po...

conclusions by measuring image quality metrics, this study showed that dtd and ctd filters with the canny edge detection respectively, are better than srad filter with the canny detection for speckle suppression and details preservation in both arteries in the ultrasound images. background ultrasonic evaluation of intima-media thickness (imt) is an early marker of assessing the development of a...

The quality of chart production is the core and soul of the foundational marine information. However, at present there exist some problems such as much repeated work, low efficiency and a great of waste in quality detection for paper charts in China. Aiming at these problems, a new method of quality detection for paper charts based on knowledge rules and quality standard database is presented i...

MOTIVATION The process of producing microarray data involves multiple steps, some of which may suffer from technical problems and seriously damage the quality of the data. Thus, it is essential to identify those arrays with low quality. This article addresses two questions: (1) how to assess the quality of a microarray dataset using the measures provided in quality control (QC) reports; (2) how...

most of the contour detection methods suffers from some drawbacks such as noise, occlusion of objects, shifting, scaling and rotation of objects in image which they suppress the recognition accuracy. to solve the problem, this paper utilizes zernike moment (zm) and pseudo zernike moment (pzm) to extract object contour features in all situations such as rotation, scaling and shifting of object i...

In the robotics, omnidirectional vision is favored because it increases the field of sensor's view allowing for better navigation and localization of robots. The Catadioptric sensors (combination of mirror (s) + camera (s)) are a quick and easy solution to reach a large view satisfactory. However, because of the geometry of the mirrors used, these sensors provide images with a nonuniform resolu...

There is an increasing emphasis on including semantic concept detection as part of video retrieval. This represents a modality for retrieval quite di erent from metadata-based and keyframe similaritybased approaches. One of the premises on which the success of this is based, is that good quality detection is available in order to guarantee retrieval quality. But how good does the feature detect...
