Many important problems in the processing of Magnetic Resonance data can be reduced to well known ill-posed inverse problems. MR relaxometry, spectroscopy and MR image formation problems can be formulated respectively as the numerical inversion of Laplace transform, the modal analysis problem and the truncated trigonometric moment problem. A unified framework to efficiently solve these problems...
Handling time delays in industrial process control is a major challenge the dominant pole placement based design of proportional-integral-derivative (PID) controllers due to variable number zeros and poles which may arise from Pade approximation exponential delay terms characteristic polynomials used for stability analysis. This paper proposes new concept designing PID with derivative filter us...
در این مقاله دو آشکارساز شبه بهینه برای آشکارسازی همدوس سیگنال رادار در کلاتر k ارائه شده است. با فرض اینکه چند ممان اولیه دامنه کلاتر در اختیار است، تابع مشخص دامنه کلاتر به صورت یک سری، با جملات محدود تقریب زده شده و بر اساس آن با استفاده از تقریب pade، به صورت یک کسر گویا در آمده و در نتیجه تابع احتمال دامنه کلاتر به صورت مجموعی از توابع نمایی به دست می آید. با استفاده از تابع احتمال حاصل، آ...
We investigate the convergence of the rows (fixed denominator degree) of the Walsh array of best rational approximants to a meromorphic function. We give an explicit algorithm for determining when convergence is guaranteed and obtain rates of convergence.in the appropriate cases. This algorithm also provides the solution to an integer programming problem that arises in the study of Pade approxi...
Analytical solutions are attractive for parametric studies and consideration of the problems physics. In addition, analytical solutions can be employed as a reference framewo...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
BACKGROUND Medication errors occur frequently in the intensive care unit (ICU) and during care transitions. Chronic medication is often temporarily stopped at the ICU. Unfortunately, when the patient improves, the restart of this medication is easily forgotten. Moreover, temporal ICU medication is often unintentionally continued after ICU discharge. Medication reconciliation could be useful to ...
