pacs is used as a way to store images and matches well with the workflow in the radiology department and can spread to other parts of hospital. integration with other pacs and other hospital systems like radiology information system (ris), hospital information system (his), and electronic patient records has been completely done, but there are still problems. pacs also provide good conditions f...
دستگاه معادلات خطی افزوده در بسیاری از محاسبات علمی و کاربردی،مثل حل تقریبی مسأله استوکس به روش عناصر متناهی ظاهر می شود. در این پایان نامه ابتدا روشهایsor-like ، ssor وmssor برای حل اینگونه دستگاه ها را مطالعه می کنیم. سپس یک پیش شرط ساز ساده اما کارا برای روش sor-like ارائه می شود. در ادامه شکل اصلاح شده ای از روشssor بنام issor ارائه می گردد. در پایان نتایج عددی برای نشان دادن کارائی روشها ر...
Numerous research works about the extraction of low-level features from images and videos have been published. However, only recently the focus has shifted to exploiting low-level features to classify images and videos automatically into semantically meaningful and broad categories. In this paper, novel classification algorithms are presented for three broad and generalpurpose categories. In de...

Statement of Problem: Computer Sciences, in radiology, like other fields, is of high importance. It should also be noted that the accuracy of the technique and work conditions affects the radiographs information considerably. There for, in order to get more accurate diagnostic information, it seems necessary to investigate different digitized radiographic techniques and to compare them with the...
Many ancient Iranian stories are artistically emblazoned by poets as well as painters and artists. The story of Bahram Gur’s hunting trip with his slave girl- Kanizak- is among a number of anecdotes about the life of the Sassanid king that has been told differently by various sources. Comparisons of the details have taken distinct art forms and descriptions. With poets like Ferdowsi and N...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
today, mass media act like a magic mirror, not only reflecting the reality of societies, but also projecting a variety of images onto people’s thoughts. because of this great ability to produce, reproduce and disperse images, mass media have acquired considerable influence on people’s lives. among the different media, the television in particular has become an inseparable part of most iranian h...
The images extracted from Tomography are complex. Tomography images like Magnetic Resonance Images (MRI), angiograms, X-rays or CT scanned images extracted from scanner are further reconstructed to analyze smallest piece or portion of the images for investigation of diseases. The MR images when they extracted from scanner are under-sampled, added with artifacts called interference. L1-norm tech...
