Three experiments compared human performance on temporal generalization tasks with either one or two different, and distinct, standard durations encoded. In the first two experiments participants received presentations of two different standards at the beginning of each trial block and were instructed to encode either one or both of them. When instructed to encode one standard they then had to ...

Memory reference locality is widely known to have an increasingly important eeect on the performance of algorithms. We demonstrate and explain why the performance of the binary tree search algorithm varies considerably depending on how the tree is laid out in the main memory. We present an algorithm which relocates a binary tree so that maximal performance can be achieved and discuss how update...

Memory is a critical resource that is non-renewable and is time consuming to regenerate by reclaim. While there are several tools available to understand the amount of memory utilized by an application, there is presently little infrastructure to capture the physical memory reference pattern of an application on a live system. This knowledge would enable the software developers and hardware des...

Age-related changes in learning and memory are common in rodents. However, direct comparisons of the effects of aging on learning and memory in both males and females are lacking. The present study examined whether memory deteriorates with increasing age in C57BL/6NIA mice, and whether age-related changes in learning and memory are similar in both sexes. Male and female mice (five, 17 and 25 mo...

at first, ground-based circular strip-map synthetic aperture radar (gb-csmsar) and its capabilities is introduced and the received signal model, 2-d frequency spectrum and the azimuth and range resolutions are derived and compared with the linear motion strip-map sar resolutions. because of the stability of the path and speed of antenna in gb-csmsar a frequency domain imaging algorithm is sugge...

Research on spatial memory indicates that locations are remembered relative to reference frames, which define a spatial reference system. Reference frames are thought to be selected on the basis of environment-based and experience-based cues present during learning. Results from new experiments indicate that reference frames provide scaffolding during the development of spatial memories: the re...
