Temporal abstraction and temporal Bayesian networks in clinical domains: a survey
(2014)Objectives: Temporal abstraction (TA) of clinical data aims to abstract and interpret clinical data into meaningful higher-level interval concepts. Abstracted concepts are used for diagnostic, prediction and therapy planning ...

Using personality metrics to improve cache interference management in multicore processors
(Association for Computing Machinery, Inc, 2017)The trend of increasing the number of cores in a processor will lead to certain challenges, among which the fact that more cores issue more memory requests and this in turn will increase the competition, or interference, ...

DBN-extended: A Dynamic Bayesian network model extended with temporal abstractions for coronary heart disease prognosis
(2015)Dynamic Bayesian networks (DBNs) are temporal probabilistic graphical models that model temporal events and their causal and temporal dependencies. Temporal abstraction (TA) is a knowledge-based process which abstracts raw ...

Adjourn state concurrency control avoiding time-out problems in atomic commit protocols
(2008)The use of atomic commit protocols in mobile ad-hoc networks involves difficulties in setting up reasonable timeouts for aborting a pending distributed transaction. This paper presents the non-blocking Adjourn State, a ...
