This paper describes a novel scheme for the fusion of spectrum sensing information in cooperative spectrum sensing for cognitive radio applications. The scheme combines a spectrum-efficient, pre-distortion-based fusion strategy with an energy-efficient censoring-based fusion strategy to achieve the combined effect of reduction in bandwidth and power consumption during the transmissions of the l...

Mental representations of environments are embodied in cognitive maps. Cognitive maps enclose spatial and distance distortions, which appear due to transcription errors based on processing of map information. Participants processed complex cartographical maps of varying amounts of visual details like topography, boundaries and grid to examine their effects on recall and orientation performance....

Iran is committed to substantial trade and market reform in its Third Five Year Development Plan. It started, however, with nontariff barriers on all products, a dual exchange rate regime with the market rate more than four times the official rate, and domestic energy product subsidies of about 90%. The authors develop a multisector computable general-equilibrium model with ten rural and ten ur...

Moral behavior is more prevalent when individuals cannot easily distort their beliefs self-servingly. Do seek to limit or enable ability beliefs? How do these choices affect behavior? Experiments with over 9,000 participants show preferences are heterogeneous—30 percent of prefer belief distortion, while 40 it, even if costly. A random assignment mechanism reveals that being assigned the prefer...

Combination of prior knowledge and implicit knowledge hidden in the data of system can enhance the quality of information services in Knowledge Grid. Fuzzy Cognitive Maps (FCMs) are constructed by experts using prior knowledge and do not acquire the implicit knowledge from the data of systems directly, which may distort the dynamical behaviour of information services systems in which knowledge ...

This article presents a critique of the concept of cognitive distortion as it has been developed within the domain of sex-offender treatment programme theory and practice. Drawing upon a discursive psychology perspective, it is argued that cognitive distortions should not be considered as mental entities but as social practices. This argument is illustrated by closely examining how offenders‟ a...

Understanding the performance of the cognitive radio systems is of great interest. Different paradigms have been extensively analyzed in the literature to perform secondary access to the licensed spectrum. Of these, Interweave System (IS) has been widely investigated for performance analysis. According to IS, sensing is employed at the Secondary Transmitter (ST) that protects the Primary Receiv...

OBJECTIVE The current study explored the clinical meaningfulness of distinguishing subjective (SBE) from objective binge eating (OBE) among individuals with threshold/subthreshold bulimia nervosa (BN). We examined relations between OBEs and SBEs and eating disorder symptoms, negative affect, and personality dimensions using both a group comparison and a continuous approach. METHOD Participant...

In sentence comprehension, what are the cognitive constraints that determine number agreement computation? Two broad classes of theoretical proposals are: (i) Representation distortion accounts, which assume feature on subject noun gets overwritten probabilistically by a non-subject noun, leading to non-veridical memory trace noun; and (ii) The cue-based retrieval account, general account depen...
