To evaluate disorders of regional wall motion in patients with coronary artery disease, we developed a method to detect the boundary of the cineventriculograms with the aid of minicomputers. Each image of the left ventriculogram, taken at 60 frames/sec, was transferred to computer through a flying spot scanner and stored in the disc. The endocardial margin was automatically traced along the max...

The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...

Affective stimuli can elicit fast and automatic responses. Traditional accounts assume a dual route mechanism with one route underlying automatic processing and one route underlying controlled processing. Recent studies show that automatic processes may be affected by top-down influences. To account for this interaction between automatic and controlled processing, we present a computational mod...
