Abstract: A comparative study of slot –entry hybrid journal bearings performance with different symmetric and asymmetric geometrical configurations has been presented. The research work includes a numerical analysis of full thermo-hydrodynamic non-recessed slot entry journal bearing. The results show the optimum number of slots for each row of double row symmetric configuration and for single row asymmetric case. The results demonstrated that the optimized asymmetric configuration has higher load carrying capacity especially at high eccentricity ratio. The effect of temperature rise on load carrying capacity of the bearing is more pronounced in symmetric than that in asymmetric configuration. Considering the stability of the bearing, the comparative study indicates that asymmetric geometric configurations have better stability compared to symmetric geometric configurations with higher threshold speed margin.

Abstract: The fields of location-tracking, ubicomp functionalities and MANET transmission strategies are yielding commendable output and justify the research effort input in them [1-53]. With present research status, the merging of these fields still has a lot to undergo. Correct protocol design approaches is a crucial factor for successful merging of these fields. However, it is currently agreed that such approaches are heuristic in nature and hence unsuitable for implementation [91]. Improvements in middleware services and ubicomp network architecture is also needed [92, 93]. A well-shaped objective in this direction of ubicomp advancement is achievement of “realism” in design and evaluation of wireless routing protocols [94]. Such investigations may generate components better adapted for studies of predictability in ubicomp. These may be required since “realism” will dripple into every feature related to ubicomp, one of which was studied previously [22] to assess the trend of Energy Consumpti
