in the present work, deoxidation and refining of 316lvm steel (low carbon vacuum melted) during the vacuum induction melting process was studied. this grade of stainless steel is one of the most important materials in medical applications. vacuum deoxidation by carbon is the first stage of 316lvm stainless steel production process. in this stage, aluminum must be absent to avoid killing the c-o...

s 18 Ghana 12 Small-scale salt producers 14 A recent multicenter study clearly demonstrates that iodine repletion in children improves growth. Because over 285 million school-age children worldwide are iodine deficient, these findings underscore the importance of global efforts to eradicate IDD in this age group. Correcting iodine deficiency improves growth in children Michael Zimmermann ICCIDD...

introduction: there are several technical features that make pet an ideal device for the noninvasive evaluation of cardiac physiology. organ motion due to respiration is a major challenge in diagnostic imaging, especially in cardiac pet imaging. these motions reduce image quality by spreading the radiotracer activity over an increased volume, distorting apparent lesion size and shape and reduci...

Bad weather conditions such as fog, haze, and dust often reduce the performance of outdoor cameras. To improve the effectiveness of surveillance and in-vehicle cameras under such conditions, we propose a method based on a dark channel prior for quickly defogging images. It first estimates the intensity of the atmospheric light by searching the sky area in the foggy image. Then it estimates the ...

|This work extends the error reduction properties of frames to an error correcting routine. It leads to complete noise removal for sparse noise for a class of frames. The results for images using Laplacian pyramids show an additional 10dB improvement over the previously demonstrated noise reduction for frames. Keywords|Frames, pyramids, noise reduction, error correction, redundancy

To estimate motion, the edges of a moving object can be detected using Active Contours. After detecting the edges throughout the duration of the motion, the contours are registered together in order to obtain the motion model parameters. This idea can be applied to motion artifacts in Magnetic Resonance Images (MRI) which are caused by patient motion during the acquisition of an MRI. Thus, if t...

The current image retrieval systems are successful in retrieving images, using keyword based approaches. However, they are incapable to retrieve the images which are context sensitive and annotated inappropriately. Content-Based Image Retrieval (CBIR) aims at developing techniques that support effective searching and browsing of large image repositories, based on automatically derived image fea...

Passive microwave (PMW) sensors are popularly applied to Earth observations. However, the satellite PMW radiometer data sometimes have non-negligible errors in geolocation. Coastline inflection methods (CIMs) widely used improve geolocation of images. they commonly require accuracy flight parameters, which difficult obtain by users. In this study, a simplified coastline method (SCIM) is propose...
