How many memory systems? Evidence from aging
- Journal of Experimental Psychology: Learning, Memory, and Cognition
, 1989
"... older (ages 63-80) adults were given procedural, semantic, and episodic memory tasks. Repetition, lag, and codability were manipulated in a picture-naming task, followed by incidental memory tests. Relative to young adults, older adults exhibited lower levels of recall and recognition, but these epi ..."

). In addition to the age by memory task dissociations, the manipulation of codability produced slower naming latencies and more naming errors (semantic memory), yet promoted better recall and recognition (episodic memory). Finally, a factor analysis of 11 memory measures revealed three distinct factors
The Impact of Memory Hierarchies on Cluster Computing
"... Using off-the-shelf commodity workstations and PCs to build a cluster for parallel computing has become a common practice. A choice of a cost-effective cluster computing platform for a given budget and for certain types of application workloads is mainly determined by its memory hierarchy and interc ..."

and interconnection network of the cluster. Finding such a solution from exhaustive simulations would be highly time-consuming and expensive; and predictions from measurements on existing clusters would be impractical. We present an analytical model for evaluating performance impact of memory hierarchies and networks
God’s organism? The chick as a model system for memory studies
- Learn. Mem
, 2000
"... Abstract The young chick is a powerful model system in which to study the biochemical and morphological processes underlying memory formation. Training chicks on a one trial passive avoidance task results in a molecular cascade in a specific brain region, the intermediate medial hyperstriatum ventr ..."

an important factor for stream-media systems. By measuring and analyzing the performance con-straints of the media server, we find the way to improve the performance of stream media server, and then improve media service. In this paper, we discuss the per-formance metrics and constraints of stream media server
EDUCATIONAL AND PSYCHOLOGICAL MEASUREMENT
"... series 360/370 computer system (or compatible systems such as Amdol or Honeywell) that provides at least 1536-K of core storage. This large amount of core storage is usually provided via a VS-1 or VS-2 virtual memory system. This program provides a factor analy-tic solution for large 3-dimensional d ..."

Measuring Consistency Costs for Distributed Shared Data
- In Proceedings of the Fifth Workshop on Languages, Compilers, and Run-Time Systems for Scalable Computers
, 2000
"... . Distributed Shared Memory (DSM) systems typically support one consistency protocol [3, 5, 6]. However, recent work [1, 11, 12, 14, 17] proposes the use of adaptive consistency based on a heuristical analysis of recent access patterns. Although heuristic-based approaches can significantly impro ..."

Residency Aware Inter-VM Communication in Virtualized Cloud: Performance Measurement and Analysis
"... Abstract—A known problem for virtualized cloud data centers is the inter-VM communication inefficiency for data transfer between co-resident VMs. Several engineering efforts have been made on building a shared memory based channel between co-resident VMs. The implementations differ in terms of wheth ..."

on the throughput and latency performance of such a shared memory channel. We believe that this measurement study not only helps system developers to gain valuable lessons and generate new ideas to further improve the inter-VM communication performance. It also offers new opportunities for cloud service providers

"... The thermomechanical performance of a shape memory alloy hybrid composite beam specimen is demonstrated and used in a preliminary validation study of a recently developed constitutive model and finite element formulation for analysis of such structures. A brief description of the thermoelastic formu ..."

Results from Nitinol material characterization testing, beam specimen fabrication processes, and base acceleration testing for measuring the dynamic response performance
Automatic Railway Classification Using Surface and Subsurface Measurements
- INTERNATIONAL CONFERENCE ON FIELD AND SERVICE ROBOTICS
, 2001
"... The proper assessment of railroad condition requires the consideration of a number of factors. Some factors, such as the condition of the ties, can be measured by inspecting features visible from the surface of the railway. Other factors, such as the condition of the ballast, require subsurface meas ..."

generate a 3-D profile of the railroad surface with a vision system that employs a laser light stripe. Subsurface measurements were made using ground penetrating radar (GPR). Principal component analysis was used to reduce the dimension of the raw data. Classifiers were trained on the resulting data using
