Budget request tackles habitat changes

Diagnosing Performance Changes by Comparing Request Flows

The causes of performance changes in a distributed system often elude even its developers. This paper develops a new technique for gaining insight into such changes: comparing request flows from two executions (e.g., of two system versions or time periods). Building on end-to-end request-flow tracing within and across components, algorithms are described for identifying and ranking changes in t...

Dynamic Threshold Modeling of Budget Changes

A family of models was given to explain how the public budgeting process, as a multi-stage institutional decision making mechanism transforms the stimuli characterized by Gaussian distribution to skew, power law distributions. While the annual change is generally incremental, deviations from this incremental changes are more frequent, than the Gaussian distribution suggests. A set of threshold ...
