Dynamic spectrum access is envisioned as a promising paradigm for addressing the spectrum underutilization problem. According to the recent ruling of Federal Communications Commission (FCC) for white-space spectrum access, white-space devices are required to query a geo-location database to determine the spectrum availability. This chapter adopts a game theoretic approach for the self-organizin...

The resource space model (RSM) is a model for organizing versatile resources in normal forms and providing uniform resource management operations. In applications, we find three important factors that influence the effectiveness of organizing and operating resources: natural semantics of resources, resource providers’ beliefs, and resource users’ beliefs. The relationship between the three fact...

nowadays, marketing managers are more concerned with identifying and understanding customer behavior in the online space. since the customers in online space are not visible, it is much essential to have more information about them to provide better services. customer segmentation is one way to improve the customer problems in an online space. identifying characteristics of customers and optima...

persian garden design is one of the main elements in the architecture and landscaping in iran and the whole lands influenced by the iranian culture. this phenomenon has always been present in iranians' life and they have had a close connection to this ancient tradition. hence, it can be said that persian garden design is one of the most crucial features in shaping landscape, in particular,...

We present a framework in which self-organizing systems can be used to perform change of representation on knowledge discovery problems, to learn from very large databases. Clustering using self-organizing maps is applied to produce multiple, intermediate training targets that are used to define a new supervised learning and mixture estimation problem. The input data is partitioned using a stat...

the development of regional logistics system is a typical self-adapting and self-organizing evolution process. According to the structures and operation of regional logistics, the self-organizing characteristics of regional logistics synergetic evolution are analyzed. Moreover, the space evolution phases of regional logistics system are educed based on the complex system theory, and the enterpr...

Pulsed power technology is used to produce transient MHD-regime plasmas having topology and dynamical behavior similar to solar and astrophysical plasmas. These plasmas are not exact scale models, but exhibit many behaviors similar to actual solar and astrophysical plasmas, for example, coUimation, kinking, and jet motion. These plasmas can also display an interaction between MHD-dynamics and n...

Semantic models play an important role in cognitive science. These models use statistical learning to model word meanings from co-occurrences in text corpora. A wide variety of semantic models have been proposed, and the literature has typically emphasized situations in which one model outperforms another. However, because these models often vary with respect to multiple sub-processes (e.g., th...

In engineering design, a set of potentially competitive designs is conceived in the early part of the design process. The purpose of this research is to help such a process by investigating algorithm that enables approximate identification of a set of inputs of real variables that return desired responses from a function or a computer simulation. We explore sequential or adaptive sampling metho...

We propose a novel type of neural networks for structural control, which comprises an adaptive input space. This feature is purposefully designed for sequential input selection during adaptive identification and control of nonlinear systems, which allows the input space to be organized dynamically, while the excitation is occurring. The neural network has the main advantages of (1) automating t...
