Diagnostic reference frames for seizures: A validation study.
INTRODUCTION We developed structured descriptions of signs and symptoms for specific seizure types (called Diagnostic Reference Frames-DRFs-by us) that can serve as a frame of reference in the process of classifying patients with epileptic seizures. In this study the validity of the DRFs for clinical use is evaluated and described. MATERIAL AND METHODS In this study we use a decision support ...
متن کاملReference Frames for Animate Vision
Animate vision systems have gaze control mechanisms that can actively position the camera coordinate system in respose to physical stimuli. Compared to passive systems, animate systems show that visual computation can be vastly less expensive when considered in the larger context of behavior. We are accustomed to thinking of the task of vision as being the construction of a detailed representat...
متن کاملReference Frames for Stellar Aberration
There is some confusion in the literature as to what velocity should appear in the stellar aberration formula. Because the aberration formula is usually derived from the same equations as the Doppler shift, where the relative velocity between source and detector is the relevant one, it is often assumed the same holds for aberration. This is not the case. Authors who choose the orbital velocity ...

در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...
15 صفحه اولLocal Diagnostic Reference Levels for Some Common Diagnostic X-Ray Examinations In Sabzevar County of Iran
Introduction: Diagnostic reference level (DRL) is a useful tool for the promotion of optimization. The national DRLs (NDRLs) are useful, brief, and robust guidelines for optimizing radiation protection in a country. The aim of this study was to extract the local DRLs (LDRLs) for some common radiologic examination in Sabzevar county. Materials and Methods: There are eight radiology departments ...
