Abstract: Researchers claim that use of MANET transmission help to save energy in ubicomp [54]. Another strategy would be by applying location-aware transmission in MANET. The resulting method of operation remains a cooperation being required from all nodes present in the topography. A desirable feature in cooperation is to know “what is the proportion of energy being required by the MANET node compared with the sending node itself, together with corresponding trends?” Such a study is provided in another paper [18] whereby a future work identified was “How to gauge Fairness features being reached”, as concerns the proportion of nodes spending more or less energy than the sender node. To bring answers to this issue, in this paper, another metric Min_R is put forward together with the corresponding model of trend over varying node densities. This paper adds up to the area of modelling in ubicomp and will be used by designers to better bound the resources and architecture needs for ubicomp. This pa

Abstract: This paper investigates the problem of designing a state observer for a Packed Bed Thermal Energy Storage System. In previous studies (see e.g. [21]), a mathematical model of the system, taking the form of two coupled partial differential equations, was derived and validated through comparison with experimental measurements. In this paper, the previously derived model is approximated by a lumped linear time-invariant model and then employed to design a Luenberger state observer capable of reconstructing the solid and fluid temperature profiles on the basis of few collocated fluid temperature measurements. Theoretical design and experimental results are presented throughout the paper.
