Visualizing impacts of an optimization pass helps to reason about, and to gain insight into, the inner workings of the optimization pass. In this paper, we visualize the impacts of two procedural abstraction passes. For this, we modified two procedural abstraction post pass optimizers to visualize for each the difference in machine code before and after(More)

There is an active research community concentrating on visualizations of algorithms taught in CS1 and CS2 courses. These visualizations can help students to create concrete visual images of the algorithms and their underlying concepts. Not only <i>fundamental algorithms</i> can be visualized, but also algorithms used in compilers. Visualizations that exist(More)
BACKGROUND Blood product transfusions are associated with increased morbidity and mortality. The purpose of this study was to determine if implementation of a restrictive protocol for packed red blood cell (PRBC) and fresh frozen plasma (FFP) transfusion safely reduces blood product utilization and costs in a surgical intensive care unit (SICU).
