The notion that there are many “universes” with different properties is one answer to the question of “why is the universe so hospitable to life?” This notion also naturally follows from current ideas in eternal inflation and string/M theory. But how do we test such a “multiverse” theory: which of the many universes do we compare to ours? This paper enumerates would would seem to be essential i...

It is widely held that propositions perform a plethora of theoretical roles. They are believed to be the semantic values of sentences in contexts, the objects of attitudes, the contents of illocutionary acts, the referents of ‘that’-clauses, and the primary bearers of truth. This assumption is often combined with the claim that propositions have their truth-values eternally. Following Kaplan’s ...

Cloud systems are now a prevalent platform to host large-scale big-data analytics applications such as machine learning and relational database. However, data privacy remains critical concern for public cloud systems. Existing trusted hardware could provide an isolated execution domain on untrusted platform, but also suffers from access-pattern-based side channels at various levels including me...

The proposed research work presents a novel approach of process oriented architecture for secure mobile commerce framework using uniquely designed hybrid mobile adhoc routing protocols using reactive and proactive type in real time test-bed. The research work discusses about deployment of mobile commerce which is one of the emerging trend in mobile applications with huge demands. Majority of th...

We argue that many future-eternal inflating spacetimes are likely to violate the weak energy condition. It is possible that such spacetimes may not enforce any of the known averaged conditions either. If this is indeed the case, it may open the door to constructing non-singular, past-eternal inflating cosmologies. Simple non-singular models are, however, unsatisfactory , and it is not clear if ...

We envision an environment where humans communicate directly with computers without additional authentication inputs like passwords, passphrases, PINs (Personal Identification Numbers), biometrics, or other existent authentication systems; and where humans network (intercommunicate) continually with wireless (mobile) devices. In this paper, we propose a new mobile authentication system, not yet...
