Problems of wound healing are commonly observed after coronary bypass grafting (CABG) operations. Our aim is to determine the prevalence and the predictors of saphenous vein harvesting complications after coronary artery bypass surgery. One hundred twenty six patients operated in the specified period were included in this prospective study. In an early period 3 patients were excluded because of...

Abstmct--We consider the convergence properties of certain algorithms arising in storhastie, discrete-time, adaptive estimation problems and operating in random environments of engineering d@hnce. We demonstrate that the algorithms operating mder ideal conditions are d e s d i l e by homogeneous time-varying linear difference equations with dependent random coefficients, while in praclical use,...
