Two neural classifiers were developed for image recognition: PCNC (Permutation Coding Neural Classifier) and LIRA (Limited Receptive Area) neural classifiers. These neural classifiers are multipurpose neural classifiers. We applied them in micromechanics. Information about shape and texture of the micro workpiece can be used to improve precision of both assembly and manufacturing processes. The...

An overview of key experimental data and theoretical representations on fracture processes in nanoceramics is presented. The focuses are placed on crack growth in nanoceramics and their toughening micromechanics. Conventional toughening micromechanisms are discussed which effectively operate in both microcrystalline-matrix ceramics containing nanoinclusions and nanocrystalline-matrix ceramics. ...

Automated fault diagnosis based on the stuckat fault model is not always effective. This paper presents practical experiences in applying a bridging fault based diagnosis technique to a TI ASIC design. Results are presented for units into which known bridging defects have been introduced via a focused ion beam (FIB) machine.

A mesh objective crack band model was implemented within the generalized method of cells micromechanics theory. This model was linked to a macroscale finite element model to predict post-peak strain softening in composite materials. Although a mesh objective theory was implemented at the microscale, it does not preclude pathological mesh dependence at the macroscale. To ensure mesh objectivity ...

Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

myocardial bridging with systolic compression of the left anterior descending coronary artery (lad) may be associated with myocardial ischemia. in symptomatic myocardial bridging unresponsive to medical treatment, surgical unroofing of the left lad can be performed. little information is available about the long-term prognosis of patients with this coronary anomaly after the surgical unroofing,...
