Of Snowstorms and Bushy Trees
Many workloads for analytical processing in commercial RDBMSs are dominated by snowstorm queries, which are characterized by references to multiple large fact tables and their associated smaller dimension tables. This paper describes a technique for bushy join tree optimization for snowstorm queries in Oracle database system. This technique generates bushy join trees containing subtrees that pr...
متن کاملExplaining 'Explaining Away'
Explaining away is a common pattern of reasoning in which the connrma-tion of one cause of an observed or believed event reduces the need to invoke alternative causes. The opposite of explaining away also can occur, in which the connrmation of one cause increases belief in another. We provide a general qualitative probabilistic analysis of intercausal reasoning, and identify the property of the...
متن کاملExplaining Simulations Through Self Explaining Agents
Several strategies are used to explain emergent interaction patterns in agent-based simulations. A distinction can be made between simulations in which the agents just behave in a reactive way, and simulations involving agents with also pro-active (goal-directed) behavior. Pro-active behavior is more variable and harder to predict than reactive behavior, and therefore it might be harder to expl...
متن کاملExplaining for Contextualizing and Contextualizing for Explaining
This paper proposes a view on the relationships between explanation and context. First, we install the background of our proposal. This background comprises two parts: the consideration of explanations in knowledge-based systems, and a preliminary observation of relationships between explanations and context. We comment briefly previous works on explanations in order to point out what is reusab...
متن کاملMeasurements of Differential Reflectivity in Snowstorms and Warm Season Stratiform Systems
The organized behavior of differential radar reflectivity (ZDR) is documented in the cold regions of a wide variety of stratiformprecipitation types occurring in both winter and summer. The radar targets and attendant cloud microphysical conditions are interpreted within the context of measurements of ice crystal types in laboratory diffusion chambers in which humidity and temperature are both ...
