Analogue brains
D igital computers and mammalian brains share not only a talent for computation but also a method that favors absolutes. The ones and zeros of a computer are analogous to the all-or-none character of action potentials in the brain. Neurons sum all incoming depolarizing signals until, at a threshold level of depolarization, an action potential fi res along the axon. Now, however, Henrik Alle and...
متن کاملAnalogue Gravity
Analogue gravity is a research programme which investigates analogues of general relativistic gravitational fields within other physical systems, typically but not exclusively condensed matter systems, with the aim of gaining new insights into their corresponding problems. Analogue models of (and for) gravity have a long and distinguished history dating back to the earliest years of general rel...
متن کاملAnalogue Methods in Palaeoecology: Using the analogue Package
Palaeoecology is an important branch of ecology that uses the subfossil remains of organisms preserved in lake, ocean and bog sediments to inform on changes in ecosystems and the environment through time. The analogue package contains functions to perform modern analogue technique (MAT) transfer functions, which can be used to predict past changes in the environment, such as climate or lake-wat...
متن کاملEvolvable Analogue Electronic Artificial Cochlea using Field Programmable Analogue Array
An evolvable analogue electronic artificial cochlea has become a practical proposition with the recent development of dynamically configurable and reconfigurable Field Programmable Analogue Arrays (FPAA). The authors describe a proof-of-concept system based on the Anadigm® FPAA that implements a four-channel evolvable cochlea on one device. A genetic algorithm (GA) can be used to arrive at an o...
متن کاملCollaborative Analogue Document Use
Paper as a means of communication has never been superseded by the almost ubiquitous electronic media of the workplace. An interview and observational study investigates the use of paper in communication. Speculations are made on how CSCW systems can incorporate these results to facilitate communication and collaboration.
