Generalized multicarrier direct sequence code-division multiple-access (MC DS-CDMA) system is a model which includes a number of specific MC DS-CDMA schemes by varying the normalized subcarrier spacing. In the generalized MC DS-CDMA scheme, for a given system bandwidth and a given channel environment, there exists an optimum subcarrier spacing, which results in a minimum bit error rate. In this...

The present work establishes the optimized spatial arrangement for an array of aligned microcantilever sensors placed inside a fluidic cell. The results of the present investigation show that the optimum spacing distance between the microcantilevers decreases as the fluidic cell height decreases. An increase in the flow Reynolds number is found to increase the optimum spacing distance. However,...

Competitive swimmers spread fingers during the propulsive stroke. Due to the inherent inefficiency of human swimming, the question is: does this strategy enhance performance or is it just a more comfortable hand posture? Here we show, through computational fluid dynamics (CFD) of a 3D model of the hand, that an optimal finger spacing (12 degrees , roughly corresponding to the resting hand postu...

The existence of two independent components of long-term memory has been demonstrated by the authors. The evidence has been derived from the authors' findings related to the optimum spacing of repetitions in paired-associate learning. The two components are sufficient to explain the optimum spacing of repetitions as well as the spacing effect. Although the molecular counterparts of the two comp...
