Under the current background of carbon neutrality, quantification neutrality in Qinling Mountains, calculation spatial service scope, and estimation economic value are great significance for improvement planning trading market. The Intelligent Urban Ecosystem Management System (IUEMS) was used to calculate sequestration Mountains. emission Mountains spatialized through model fitting, using nigh...

The underlying idea of the ESOM [2] is to incorporate the topological neighborhood preserving property of Self-Organizing Map (SOM) and the convex-hull property (a global optimality) of TSP together. The learning rule of its generalized version is as follows: ! w j(t+ 1) = cj(t) [ ! w j(t) + j(t) ( ! x t !w j(t))] where !w j is the weight of jth neuron, !x t the input city coordinate, cj(t) the...

In the scope of the decisions making process, groups are obtaining gradually a major role, either as form of information accomplishment, or in the scope of participative management, or even as result of requirement to improvement group efficiency in organizations. It is in this context that group decisions support systems (GDSS) is being subject of study by several researchers. However, the tec...

Almost a century has passed since valence bond (VB) theory was originally introduced to explain covalent bonding in the H2 molecule within a quantum mechanical framework. The past century has seen constant improvements in this theory, with no less than two distinct Nobel prizes based on work that is essentially developments in VB theory. Additionally, ongoing advances in both methodology and co...
