An Analog Characterization of the Grzegorczyk Hierarchy
TLDR
We study a restricted version of Shannon's general purpose analog computer in which we only allow the machine to solve linear differential equations. Expand

Reliable Crop Identification with Satellite Imagery in the Context of Common Agriculture Policy Subsidy Control
TLDR
We propose an automatic control system to partially replace CAPI for crop identification, with the overreaching goal of reducing control costs and completion time. Expand

Robust Simulations of Turing Machines with Analytic Maps and Flows
TLDR
In this paper, we show that closed-form analytic maps and flows can simulate Turing machines in an error-robust manner. Expand

Assessing the extent of agriculture/pasture and secondary succession forest in the Brazilian Legal Amazon using SPOT VEGETATION data
Abstract There has been growing concern about land use/land cover change in tropical regions, as there is evidence of its influence on the observed increase in atmospheric carbon dioxideExpand

Computational complexity of real valued recursive functions and analog circuits
TLDR
The theory of analog computation, where the internal states of a computer are continuous rather than discrete, has enjoyed a recent resurgence of interest. Expand

Iteration, Inequalities, and Differentiability in Analog Computers
TLDR
We consider whether the set G of GPAC-computable functions is closed under iteration, that is, whether for any function f(x)?G there is a function F(x, t)=ft(x) for nonnegative integers t. Expand

Computability with polynomial differential equations
TLDR
In this paper, we show that there are initial value problems defined with polynomial ordinary differential equations that can simulate universal Turing machines in the presence of bounded noise. Expand

Estimation of Effective Resolution for Daily MODIS Gridded Surface Reflectance Products
TLDR
We estimate the point spread function (PSF) of nominal 250-m MODIS gridded surface reflectance products from sequences of daily images over man-made large-size targets. Expand

Ecological Implications of Fine-Scale Fire Patchiness and Severity in Tropical Savannas of Northern Australia
Understanding fine-scale fire patchiness has significant implications for ecological processes and biodiversity conservation. It can affect local extinction of and recolonisation by relativelyExpand
