Scalable Distributed Temporal Reasoning
2017In this paper, we propose the design and implementation of a large-scale qualitative temporal reasoner, MRQUTER, which can perform reasoning over large Web-scale knowledge bases. This temporal reasoner is built on a Hadoop cluster system using the MapReduce parallel programming framework.

Temporal distribution of carbonatites
Geology, 1992About half of the 330 occurrences listed in the global inventory of carbonatites have been dated, mostly by the K-Ar method, and they fall into groups that appear to be temporally and spatially linked to major orogenic events. Overall, however, the temporal pattern is one of exponential increase in frequency with time.

Local and temporal predicates in distributed systems
ACM Transactions on Programming Languages and Systems, 1995The definitions of the predicates Possibly φ and Definitely φ, where φ is a global predicate of a distributed computation, lead to the definitions of two predicate transformers P and D . We show that P plays the same role with respect to time as

Spatial and Temporal Distribution of Energy
Health Physics, 1988Studies of the spatial and temporal distribution of microscopic radiation doses lead to potentially important questions regarding conventional approaches to radiation protection. The short ranges of alpha-particle and Auger-electron emissions from radionuclides lead to uncertainties in assessing their hazards.

Spatio-temporal Modeling of Mosquito Distribution
AIP Conference Proceedings, 2011We consider a quasilinear parabolic system to model mosquito displacement. In order to use efficiently vector control tools, like insecticides, and mechanical control, it is necessary to provide density estimates of mosquito populations, taking into account the environment and entomological knowledges.

Temporal distribution of myocardial infarction pain
Psychosomatics, 1982Abstract The possible association between certain times of the day and the onset of the pain of myocardial infarction has not previously been examined. Of 74 patients with documented myocardial infarction, 34 experienced the onset of typical chest pain between 8 am and 10 am or between the same hours in the evening.

Temporally distributed symptoms in a diagnostic application
Artificial Intelligence in Engineering, 1991Abstract For various reasons many diagnostic expert systems do not explicitly represent time. In a number of cases this is a useful abstraction. In other applications — such as MOLTKE's —, however, some symptoms evolve over time in a characteristic manner and require several measurements which have to be carried out in a particular temporal order. In

Distributed relational temporal difference learning
International Joint Conference on Autonomous Agents and Multiagent Systems, 2013Relational representations have great potential for rapidly generalizing learned knowledge in large Markov decision processes such as multi-agent problems. In this work, we introduce relational temporal difference learning for the distributed case where the communication links among agents are dynamic.

A temporal approach for testing distributed systems
IEEE Transactions on Software Engineering, 2002This paper deals with testing distributed software systems. In the past, two important problems have been determined for executing tests using a distributed test architecture: controllability and observability problems. A coordinated test method has subsequently been proposed to solve these two problems.
