The spectral handoff is important in cognitive wireless networks to ensure an adequate quality of service and performance for secondary user communications. This work presents a multivariable algorithm for dynamic channel selection used in cognitive wireless networks. The channel selection is based on the fuzzy analytical hierarchical process (FAHP) method. The selected criteria for choosing th...

The paper presents a conceptual model based case study of information processes and threats of the most fast progressing social network in Internet for 2010 – Facebook. The key idea is to study the Web.2 technology feedback effects in social networks by using E-R system notation and software environment for modelling and simulation support. The obtained results are based on high-level subject m...

Introduction. The Delphi technique is widely used in library and information science research. However, many researchers in the field fail to employ standard statistical tests when using this technique. This makes the technique vulnerable to criticisms of its reliability and validity. The general goal of this article is to explore how nonparametric statistical techniques could mitigate this dra...

The world-wide diffusion and recognition of Technology Foresight suggests that it is of value for quite diverse types of economies and societies. Its merit as an important tool of strategic intelligence for policy-making also in small countries and transition economies depends on a careful tailoring to specific needs. Practice of Foresight is rather diverse also among small countries, but appro...

Recent advances in information technology management reflect the growing understanding that the most significant asset at risk is not hardware or facilities but, rather, the information that those assets service. An ongoing debate exists as to how—or whether—information can be valued. This chapter provides an overview and detailed guidance for one proven method of information valuation, the Del...

tion techniques, such as predictive deconvolution or Radon transforms, fail in the presence of complex structures. A technique popularized by the Delphi consortium offers an attractive alternative in 2-D because it is theoretically independent of subsurface structure and can therefore attack all surface-related multiples regardless of their complexity. The Delphi approach can be summarized by t...

Delphi is a powerful technique used to seek answers to appropriate questions. The purpose of this paper is to provide an overview of the Delphi technique as a research method. This paper discusses the scientific merit of the Delphi technique by investigating on 41 studies of Journal of Agricultural Education from 1981 to 2013, and 2 studies of Journal of Agricultural Science and Technology. The...
