In this paper, we describe the r~ults of several tests that check the accuracy of numerical computation on the Cray sttpercomputer in vector and scalar mod~s. The known tests were mtwlified to identify the critical ~}int where rtmndings start causing problems. After describing the tests, we present ;in interval library called libavi.a. It was developed in Fortran 90 on the Cray Y-MP2E supercomp...

ventricular arrhythmias are one of the most important causes of annual deaths in the world, which may lead to sudden cardiac deaths. accurate and early diagnosis of ventricular arrhythmias in heart diseases is essential for preventing mortality in cardiac patients. ventricular activity on the electrocardiogram (ecg) signal is in the interval from the beginning of qrs complex to t wave end. vari...

Sphere structured support vector machine is a multi-classification algorithm. The algorithm separately constructs sphere for each class sample data, so the complex degree of the quadratic programming is reduced and it is easier to extend new samples. But, kernel parameter selection of sphere structured support vector machine needs to predetermine the parameter search interval. For eliminating h...

Lutzomyia migonei is a vector of leishmaniasis with a wide distribution in South America, which could favour population differentiation and speciation. Cryptic species of the Lutzomyia longipalpis complex, the widely distributed sand fly vector of visceral leishmaniasis in Latin America, have previously been shown to display distinct copulation songs. We found that Lu. migonei males also produc...
