This paper summaries our recent work on the application of the concepts of capacity per unit cost and reliability function per unit cost to models of fading channels. The cost is taken to be the energy, or a certain fourth moment functional that is sensitive to the bursti-ness of the signals, and is related to the ambiguity function of the input signal. The channel is assumed to be a Wide-Sense...

This empirical study which is based in Malta seeks to characterize the personality/psychological profile of Maltese entrepreneurs (business owners and self-employed persons) and employed managers. The characteristics investigated in this study are the need for achievement, locus of control, tolerance towards ambiguity, self-confidence, creativity/innovativeness, risk-taking propensity and self-...

AIMS AND OBJECTIVES To redefine the practice of rural nurses and describe a model that conceptualises the capabilities and characteristics required in the rural environment. BACKGROUND The way in which the practice of rural nurses has been conceptualised is problematic. Definitions of rural nursing have been identified primarily through the functional context of rural health service delivery....

Five hundred and forty five Chinese students participated in study aimed to examine multi-dimensionality of creativity self-efficacy and its contextual (i.e., classroom environment) correlates. Nearly all aspects in the What Happens in the Classroom Scale (e.g., student cohesiveness, investigation, and task orientation) were found to have significant, positive correlations with all subscales of...

We analyzed the effect of time and frequency domain windowing, or weighting, of the transmitted signal for least squares (LS) and minimum mean-square error (MMSE) estimators when the channel is time-variant. We considered the estimation error for different windows and we found that the windows can be selected independently. We explained the performance of the estimators with the help of the rad...
