Auditory brainstem response (ABR) absolute thresholds were obtained from 31 ears of 28 newborns using both the insert and the earphone methods to deliver the stimuli. The two estimates on each ear were acquired in a single test session, and they differed by 10 dB or less in all cases. The results suggest that when the earphone is used, it rarely if ever collapses the ear canal to cause an artif...

Active object-oriented databases provide two means to model behavior of objects: (1) methods and (2) rules. In many cases methods and rules can be used interchangeably to achieve the same eeect. If clear design guidelines are missing and comparable situations are realized differently , information systems can become hard to understand and hard to maintain. Moreover, it is known that large sets ...

Since cryptosystem based on the problem of factoring the composite number N can be attacked with P − 1 and P +1 methods, it is required that P −1 and P +1 should be difficult to be factored into many small primes, where we assume that the P is a factor of N . In this paper, first, we consider the distribution of secure primes against both P −1 and P +1 methods. Second, we propose two efficient ...
