magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...

بیهوشی را می توان فرآیندی قلمداد کرد که منجر به از دست رفتن هشیاری، شل شدن عضلات و عدم دریافت تحریک دردناکی می گردد. اطمینان از کافی بودن عمق بیهوشی به هنگام عمل جراحی و در اتاق مراقبت های ویژه امری ضروری و لازم به نظر می رسد. در صورت غفلت از کنترل دقیق عمق بیهوشی، احتمال بروز حالاتی چون هشیاری ناخواسته در حین عمل جراحی و یا عدم بازگشت بیمار به هشیاری وجود دارد. به منظور پیشگیری از حوادث فوق، ب...
this paper addresses the signal processing principles in passive bistatic radar (pbr) systems. in this case, the detection problem in the presence of system noise, clutter/multipath, direct signal and interfering target signals is investigated. to this light, two types of detectors are studied. in the first one, which is based on intuitive sense, we examine two detectors. in the second type det...
Sidelobe blanking (SLB) is a technique employed in radar signal processing to inhibit detection when an unwanted signal enters the radar receiver through antenna sidelobes. For this purpose, an auxiliary antenna and receiver channel are used in the radar system. Comparing the main antenna and auxiliary antenna signal strength, a decision is made for blanking the main channel output. In this pap...
In this manuscript, we proposed a new scheme in communication signal detection which is respect to the curve shape of received signal and based on the extraction of curve fitting (CF) features. This feature extraction technique is proposed for signal data classification in receiver. The proposed scheme is based on curve fitting and approximation of rational fraction coefficients. For each symbo...
Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...
although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. however, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. a type of verification known as the circularity check for the shap...
