The problem of opportunistic spectrum access in cognitive radio networks (CRNs) is considered in this paper. Especially, we discuss designing distributed learning protocols for non-cooperative secondary users (SUs) to efficiently utilize the spectrum opportunities. It is well known that the SUs’ selfish behaviors will result in a network collapse. Each SU is thus enabled to form conjectures ove...

The aim of this study is to explore the strategic applications and limitations of Timedriven Activity-based Costing (TDABC) and to evaluate the degree of accuracy of the proponents’ arguments concerning its usefulness. In this study, published works directly related to this area from the period 2004-2015 are analyzed. This study reports TDABC's applications in strategic areas such as cost of pr...

This study posits that the use of artificial intelligence (AI) enables supply chains (SCs) to dynamically react volatile environments, and alleviate potentially costly decision-makings for small-medium enterprises (SMEs). Building on a resource-based view, this work examines impact AI SC risk management SMEs. A structural model comprising AI-risk capabilities, re-engineering capabilities chain ...

The article highlights the new realities in international freight transportation emerged under simultaneous challenges, related to global economic crisis, climate change and COVID-19 pandemic consequences. authors argue that seaborn trade has been encountering a fundamental disorders long before contemporary shocks emergence. Additionally container caused by shortage of free containers its grow...

Introduction. Accreditation has a long antecedence in western countries educational systems and its history of implementation is more than a century in a country such as United States of America. In European countries, also different activities have been implied throughout the accreditation and its implementation has become an essential. Now, in our country the experts also think of the accredi...

Members of effective human teams can often anticipate information needs of teammates and offer relevant information to them proactively. Such capabilities are highly desirable for agent teams to achieve better teamwork processes for supporting information gathering, information fusion, and decision makings of teammates. However, there is a lack of agent theories for specifying such proactive ag...

INTRODUCTION Nursing care is considered as an essential component of health services. Patients' health improvement depends upon the quality of nursing care. As an important principle, perceptions of nurses as well as their active participation in decision-makings has an important role in the quality of services. This study aimed to determine the percep-tion of nurses toward the quality of nursi...

Like the majority of the university establishments in the former USSR , Al Farabi university functions, for historical reasons, according to a very centralized model: this model imposes significant collections of information and permanent data exchanges which are done by heavy, complex procedures and often not very reliable. The absence of global views and management reports as well as slowness...

Electricity prices are notoriously hard to model due to their exotic behav-iors. The extraordinarily high volatilities, strong mean reversion, pronouncedcyclical price patterns, and occasional occurrence of price spikes may demandvery complicated models.From the empirical analysis with the Dutch and German electricity mar-ket data, we …nd that the two-state regime switching ...

For building design, computational intelligence systems use a knowledge base formed by means of neural network and fuzzy logic (neuro-fuzzy) techniques, from a building design database. The application of such a system to a building design task was preliminarily demonstrated earlier. The present research describes a systematic neural fuzzy modelling of data that forms a knowledge base in a hier...
