Errors of Computer Electrocardiography Revisited

The forward problem of electrocardiography revisited.

Firewall Configuration Errors Revisited

Practically every corporation that is connected to the Internet uses firewalls as the first line of its cyber-defense. However, the protection that these firewalls provide is only as good as the policy they are configured to implement. The first quantitative evaluation of the quality of corporate firewall configurations appeared in 2004, based on Check Point FireWall-1 rule-sets. In general tha...

Computer Simulation of the Inverse Problem of Electrocardiography

The problem of reconstructing the pattern of heart excitation from body surface potentials is simulated. The problem is well known as the inverse problem of electrocardiography and in a general case this problem has a non-unique solution. The relationship of the problem with the inverse problem of potential theory is shown. From this relationship a new excitation propagation model for the heart...

Proposing an Efficient Software-based Method to Enhance Reliability of Computer Systems against Soft Errors

In recent years, along with rapid developments in technology, computer systems haveincreasingly become more integrated and more modular. Indeed, the reliability and efficiency ofcomputer systems are of high significance. Hence, the quantitative evaluation of the optimizationof reliability indexes in computer systems is considered to be a crucial issue. Reliabilityenhancement of computer systems...
