background: acute kidney injury (aki) is a common problem in critically ill patients and is independently associated with increased morbidity and mortality. recently, serum cystatin c has been shown to be superior to creatinine in early detection of renal function impairment. we compared estimated gfr based on serum cystatin c with estimated gfr based on serum creatinine for early detection of ...
background glomerular filtration rate (gfr) is widely estimated by serum creatinine based equations such as cockcroft-gault (cg) standardized for body surface, and an abbreviated formula derived from mdrd (modification of diet in renal disease) study. however, some studies suggested that creatinine based estimation of gfr formula can be replaced by cystatin c based formula. objectives the aim o...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
برای اطمینان از درستی کارکرد فرآیند های صنعتی، نیاز به ابزارهایی است که وضعیت های نامطلوب عملکرد فرآیند را با دقت و سرعت بالا به راهبر فرآیند نشان دهد. کاربرد یک روش موثر برای تشخیص و شناسایی عیوب، به کاهش اثر این عیوب، تأمین ایمنی عملیات، کم کردن زمان مرده و کاهش هزینه های ساخت کمک می کند .در حال حاضر شبکه های bayesian belief، از جمله روش های مورد توجه جهت تعیین و تشخیص عیوب فرآیندها به شمار م...
در این پروژه، الگوریتمی را برای بررسی عنبیه چشم انسان معرفی می کنیم. الگوریتم های تشخیص عنبیه در فاصله ها ی طولانی به دلیل کاربرپسندانه بودن و ایجاد یک روش اقتصادی برای شناسایی، گسترش یافته اند. الگوریتم ما، روی تشخیص مردمک متمرکز شده است؛ و با استفاده از محدوده های تخمین زده شده، مناطق دیگر را برای جستجوی فضای کارآمد حذف می کنیم. در این آزمایش 3 تصویر از هر شرکت کننده برای ثبت نام سیستم و 16 ت...
cystatin c is a 13 kd basic protein that is a member of the cystatin superfamily of cysteine protease inhibitors. the cystatin c gene seems to be a house keeping gene, which is compatible with a stable production rate of cystatin c by most cells. this protein is freely filtered through the glomerulus and almost completely reabsorbed and catabolized by proximal tubular cells. because of these ch...
reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...
