Falls are the leading cause of injury-related morbidity and mortality among elderlypersons and are associated with significant adverse psychological andphysical consequences [1].Evaluating fall risk is important because it allows better targeting for preve ...
Although transactional models have proved to be very useful for numerous applications, the development of new models to reflect the ever-increasing complexity and diversity of modern applications is a very active area of research. Analysis of the existing ...
In a transactional system, an atomic commitment protocol ensures that for any transaction, all data managers agree on the same outcome: commit or abort. A non-blocking atomic commitment protocol enables an outcome to be decided at every correct data manage ...
In a transactional system, an {\em atomic commitment} protocol ensures that for any transaction, all {\em Data Manager} processes agree on the same outcome {\em (commit} or {\em abort)}. A {\em non-blocking atomic commitment} protocol enables an outcome to ...
Database replication protocols have historically been built on top of distributed database systems, and have consequently been designed and implemented using distributed transactional mechanisms, such as atomic commitment. We present the database state mac ...
This paper discusses the relationship between the {\em Non-\Blocking Atomic Commitment problem (NB-AC)} and the Consensus problem in asynchronous systems with {\em unreliable} failure detectors. We first confirm that NB-AC is harder than Consensus. In con ...
