Purging of untrustworthy recommendations from a grid
In grid computing, trust has massive significance. There is lot of research
to propose various models in providing trusted resource sharing mechanisms. The
trust is a belief or perception that various researchers have tried to
correlate with some computational model. Trust on any entity can be direct or
indirect. Direct trust is the impact of either first impression over the entity
or acquired during some direct interaction. Indirect trust is the trust may be
due to either reputation gained or recommendations received from various
recommenders of a particular domain in a grid or any other domain outside that
grid or outside that grid itself. Unfortunately, malicious indirect trust leads
to the misuse of valuable resources of the grid. This paper proposes the
mechanism of identifying and purging the untrustworthy recommendations in the
grid environment. Through the obtained results, we show the way of purging of
untrustworthy entities.Comment: 8 pages, 4 figures, 1 table published by IJNGN journal; International

Understanding Gravity: Some Extra Dimensional Perspectives
Gravity is one of the most inexplicable forces of nature, controlling
everything, from the expansion of the Universe to the ebb and flow of ocean
tides. The search for the laws of motion and gravitation began more than two
thousand years ago but still we do not have the complete picture of it. In this
article, we have outlined how our understanding of gravity is changing
drastically with time and how the previous explanations have shaped the most
recent developments in the field like superstrings and braneworlds.Comment: 21 page
