An analysis of errors in finite automata
(Elsevier, 1965-06)
This paper studies errors in finite automata. An error is defined as a pair of states and errors are then classified according to their probability of being corrected (i.e., being taken into the same state). Various results ...
Spatial distribution and seasonal variation in 18 O/ 16 O of modern precipitation and river water across the conterminous USA
(John Wiley & Sons, Ltd., 2005-12-30)
We report a quantitative analysis of regional differences in the the oxygen isotope composition of river water and precipitation across the USA because data are now available to undertake a more geographically and temporally ...
Variability of in‐stream and riparian storage in a beaded arctic stream
(John Wiley & Sons, Ltd, 2012-09-15)
The extent and variability of water storage and residence times throughout the open water season in beaded arctic streams are poorly understood. Data collected in Imnavait Creek, a beaded stream located north of the Brooks ...
On the measurement and use of time-varying communication channels
(Elsevier, 1965-08)
In radio, radar, sonar, and seismic signal detection there is often the problem of processing received signals which have been distorted by a linear operation in the process of being transmitted. Examples are scattering ...
On the statistics of random pulse processes
(Elsevier, 1971-05)
Statistics are obtained for pulse trains in which the pulse shapes as well as the time base are random. The general expression derived for the mean and spectral density of the pulse train require neither independence of ...
The theoretical channel capacity of a single neuron as determined by various coding systems
(Elsevier, 1960-12)
The information channel capacity of a model neuron with a fixed refractory period [delta] has been calculated for optimum continuous time interval coding. Two types of noise perturbations have been considered, a Gaussian ...
A logic for constant-depth circuits
(Elsevier, 1984-04)
Consider a family of boolean circuitsC1,C2,...,Cn,..., constructed by some uniform, effective procedure operating on inputn. Such a procedure provides a concise representation of a family of parallel algorithms for computing ...
Hydrologic and biogeochemical controls on the spatial and temporal patterns of nitrogen and phosphorus in the Kuparuk River, arctic Alaska
(John Wiley & Sons, Ltd., 2008-08-15)
Nitrogen (N) and phosphorus (P) dynamics in the Kuparuk River in arctic Alaska were characterized in a 3-year study using routine samples near the mouth of the river at the Arctic Ocean, synoptic whole-river surveys, and ...
On the relationships between Scott domains, synchronization trees, and metric spaces
(Elsevier, 1985)
We use Scott's idea of information systems to provide a complete partial order semantics for concurrency involving Milner's synchronization tree model. Several connections are investigated between different models; our ...
