A theory of semiflows with a discrete acting topological semigroup was developed in the 2000 paper by D. Ellis, R. Ellis and M. Nerurkar ([2]). A theory for the case of an arbitrary acting topological semigroup has still to be developed. This paper can be considered as the beginning of an attempt in that direction. We discuss almost periodicity and G-almost periodicity of points in a semiflow a...

and that its computation presents a challenge in arithmetic. Such arguments are the antithesis of the scientific method since it presents no sound basis for rejecting or refining a model that has been proposed and is in use. Spring did not show that his model gave a better prediction than the Ellis formula for the total dose required, whereas Ellis has shown some success for his model (1). He d...

Information seeking behavior is a specific activity or project that carried out on an individual basis in order to find information required desired accomplish certain goal. David Ellis' model of searching the one became guiding principle this study. Starting (awalan), Chaining (menghubungkan), Browsing (menelusur), Differentiating (pemilahan), Monitoring (memantau), and Extracting are steps in...

The most basic properties of whole-tree root systems have remained essentially impossible to determine non-destructively. The alternative, excavation and destructive root sampling, remains the bane of root physiologists’ existence. In this issue, Ellis et al. (2013) have made progress on electrical capacitance, one of the more promising non-destructive techniques to disentangle the belowground ...

Wormholes with Ellis geometry have been successfully constructed using tachyon matter \cite{Das}. However, for such a wormhole, it is obtained that the redshift function necessarily constant, and also wormhole plagued an imaginary potential constant field if solutions are in absence of cosmological term. So, physically plausible solution possible only presence $\Lambda$ In this paper, we try to...
