In order to solve the problem in that classical forest land expectation value method ignores actual stock volume when assessing income at end of current production cycle forest, and fill research gap this area, technical system asset evaluation was enriched. The returns were divided into two parts, i.e., segmented return price from growth stand (Bu1), for an infinite number cycles after (Bu2). ...

A simple method that incorporates coupling between bath and system and between individual bath modes is proposed. In Ž . the new locally propagating gaussian LPG approximation, the bath is modeled by Gaussians at each system site that propagate in time. Each site couples to others by the overlap of their Gaussians. In a test case with weak but non-negligible coupling, LPG is nearly as rapid as ...

We present some techniques for planning in temporal domains specified with the recent standard languange PDDL2.1. These techniques are implemented in LPG, a fully-automated system that took part in the third International Planning Competition (Toulouse, 2002) showing excellent performance. The planner is based on a stochastic local search method and on a graph-based representation called “Tempo...

Limited and uneven distributed water resources have become one of the main obstacles to China's sustainable development, “virtual hypothesis” (VWH) is expected help mitigate stress. This study discusses virtual transfer pattern stress in China from VWH perspective. Economic sectors are divided into land-dependent non-land-dependent according their dependence on specific local land types. Furthe...

Land fragmentation and small plots are the main features of rural environment Galicia (NW Spain). Smallholding limits land use management, representing a drawback in local forest planning. This study analyzes potential multitemporal Sentinel-2 images to detect control cuts very pine eucalyptus located southern Galicia. The proposed approach is based on analysis NDVI time series 4231 smaller tha...

From the two aspects of land quantity and spatial distribution, this article studies existing problems ideas for optimizing supply medical health (M&H) municipal units to promote an equal urban public services. Method: The were explored with help kernel density, gravity model buffer zone analysis method, key optimization areas M&H under trends population flow by constructing a suitabili...

Recently we presented a method for modeling a quantum system to a bath that explicitly correlates the system with the individual bath modes. We do this through representation of the bath by locally propagating Gaussians (LPG), which change in position and momentum but remain Gaussian in form. The explicit correlation of the system to the bath modes enters through the simultaneous use of a di†er...

The ambient index and temperature effects on the spectral profiles of two sets of long period gratings (LPGs) of different periods were investigated. The shorter period LPGs were found to be more sensitive than the longer period LPGs over identical ambient index ranges but less sensitive over identical temperature ranges. The coupling wavelength shifts due to temperature are also seen to be lin...

The perceptron algorithm with margins is a simple, fast and effective learning algorithm for linear classifiers; it produces decision hyperplanes within some constant ratio of the maximal margin. In this paper we study this algorithm and a new variant: the perceptron algorithm with uneven margins, tailored for document categorisation problems (i.e. problems where classes are highly unbalanced a...
