Information theory has recently been employed to specify more precisely than has hitherto been possible man's capacity in certain sensory, perceptual, and perceptual-motor functions (5, 10, 13, 15, 17, 18). The experiments reported in the present paper extend the theory to the human motor system. The applicability of only the basic concepts, amount of information, noise, channel capacity, and r...

This paper is devoted to the study of cellular communications using aerial platforms (APs). A set of key equations is derived that quantify the coverage area on the ground as a function of AP elevation, the operation of the adaptive multibeam antenna on the AP, and the formulation of contiguous terrestrial cells and their shapes. Specifically, we consider the deployment of an AP to provide terr...

the study of flow in compound channels with vegetated floodplains is essential to assessing the development of the stage-discharge relationship and sediment and pollutant transport. the present study experimentally investigated mean flow and turbulence characteristics in a prismatic compound channel. the experimental program consisted of vegetated and non-vegetated floodplains with different re...

This paper addressed the impacts of latency on good throughputs of a computer network. The networks latency contributed largely on the performance of Covenant University network. Experiment using the University network were carried out with the channel capacity, the file sizes with the distance varies to suit the performed experiment. The Mathlab/Simulink and Netcracker Professional systems wer...

In this paper, we carefully explore the assumptions behind using information capacity equivalence as a measure of correctness for judging transformed schemas in schema integration and translation methodologies. We present a classification of common integration and translation tasks based on their operational goals and derive from them the relative information capacity requirements of the origin...

The information capacity of general forms of memory is formalized. The number of bits of information that can be stored in the Hopfield model of associative memory is estimated. It is found that the asymptotic information capacity of a Hopfield network of N neurons is of the order N3 b. The number of arbitrary state vectors that can be made stable in a Hopfield network of N neurons is proved to...

Various scenarios are considered where some information is more important than other and needs better protection. A general theoretical framework for unequal error protection is developed in terms of exponential error bounds. It provides some fundamental limits and optimal strategies for such problems. A new class of problems called message-wise unequal error protection is also analyzed. Even f...

We compare the capacity CZF of an idealized zero-forcing decision-feedback equalization (ZF-DFE) system to the capacity C of the underlying Gaussian-noise channel. We find that, for strictly bandlimited channels, the capacity penalty gets vanishingly small as the signal power increases. For non-strictly bandlimited channels, on the other hand, the capacity difference C − CZF grows without bound...

We derive an analytical expression for the bit-error rate (BER) of optimal single user detection of a binary phaseshift keying signal corrupted by multiple cochannel interferers. The channel capacity is also calculated to investigate the BER performance.

In this paper, community capacity building (CCB) is seen as part of a long-standing health promotion tradition involving community action in health promotion. The conceptual context of the term CCB is presented, and compared with other community approaches. The usage of the term is variable. It is submitted that its common features are (i) the concepts of capacity and empowerment (versus diseas...
