The problem of handling data that falls on a nonequally spaced grid occurs in numerous fields of science, ranging from radio-astronomy to medical imaging. In MRI, this condition arises when sampling under time-varying gradients in sequences such as echo-planar imaging (EPI), spiral scans, or radial scans. The technique currently being used to interpolate… (More)
This paper presents a summary of the aspects of Ada that make optimization more difficult than for simpler languages such as C. Points made are that Ada is low in "distributed overhead" but that this is only so if compilers are very careful to ensure it; and that more optimization is needed for Ada than for other languages. Specific language features and… (More)

Performance Anomalies, segments of a program which demand many more computational resources than the source code implies, are inevitable results of high-level languages and software engineering techniques. The Code Performance Anomaly Detector (CPAD) is a software agent which runs as part of the EACM (Expert Avionics Code Modification) Environment, a system… (More)
