The problem of non-linear systems excited by random forces with known power spectral density functions and unspecified probability structure is considered. Sufficient, but not necessary, conditions on the input under which the response can be a Gaussian process are investigated. The approach is illustrated by investigating the hardening spring cubic(More)
rates ranged between I58 and I94 a minute. This phnomenon (also observed by Lewis, Feil, and Stroud, I918-I920) was manifested by a gradual prolongation of the stimulus-to-atrial electrogram intervals until one stimulus failed to reach the recording electrodes. The localization of the site ofdelay and block could be made exclusivelyfrom the intracardiac(More)
This paper evaluates the performance of 198 ambulatory surgery centres (ASCs) operating in the State of Pennsylvania during the fiscal year 2006. Performance is assessed from technical efficiency view using data envelopment analysis (DEA). Multi-input/output model included two inputs: number of operating rooms and labour, and patient surgical visits(More)
Continuous monitoring of ambulatory patients has been of great value in the evaluation of paroxysmal rapid arrhythmias and of conduction disturbances as well as in the objective assessment of their therapy. This applies to both pharmacological and electrical treatment. However, it should be stressed that disorders of rhythm in general should be analyzed not(More)
