Bain on neural networks.
In his book Mind and body (1873), Bain set out an account in which he related the processes of associative memory to the distribution of activity in neural groupings--or neural networks as they are now termed. In the course of this account, Bain anticipated certain aspects of connectionist ideas that are normally attributed to 20th-century authors--most notably Hebb (1949). In this paper we rep...
متن کاملRebreathing and the bain circuit
increase upon being told that the child had eaten a few hours ago. I knew enough to realize that this was a bad thing! The surgeon and his assistant assured me that they would monitor my performance closely and I was not to be concerned. "Don't worry," they said. I placed several layers of gauze on the appropriate frame, held it over the patient's face and began to drop ether onto the gauze. It...
متن کاملDetermination of Gain and Phase Margins in Lur’e Nonlinear Systems using Extended Circle Criterion
Nonlinearity is one of the main behaviors of systems in the real world. Therefore, it seems necessary to introduce a method to determine the stability margin of these systems. Although the gain and phase margins are established criteria for the analysis of linear systems, finding a specific way to determine the true value of these margins in nonlinear systems in general is an ongoing research i...
متن کاملQueueing systems on a circle
Consider a ring on which customers arrive according to a Poisson process. Arriving customers drop somewhere on the circle and wait there for a server who travels on the ring. Whenever this server encounters a customer, he stops and serves the customer according to an arbitrary service time distribution. After the service is completed, the server removes the client from the circle and resumes hi...
متن کاملComparison of the Bain and the ADE systems during controlled ventilation in adults.
It has been suggested that Humphrey's ADE system may be an improvement on the Bain system. To compare their efficiencies we have studied 20 anesthetized adults who had controlled ventilation established with a circle absorber system at a VE sufficient to maintain normocapnia. Patients were then randomly allocated to either a Bain or an ADE system. Fresh gas flow was sufficient to keep PE'CO2 co...
