The purpose of this study was to test the hypothesis that four-year
old children would better remember what happened in science
experiments, and the basic concepts involved in them, when presentation
of the experiments involved an element of surprise. Surprise
for this study was considered as a situation in which...
This experiment used a choice recognition time task. The subjects task was to decide whether a probe tone was or was not among a presented set of one to four tones. One of three cue conditions occured on each trial: the cue (a light) was presented immediately following the tone...
The motivation of this research is to study different cache designs for on-chip
caches that improve processor performance and at the same time
minimize the degradation to system performance caused by an increase in
the processor memory traffic. As VLSI technology advances we can have
bigger and more complex on-chip...
Three types of magnetic memory elements with emphasis
placed on low cost and batch fabrication are investigated.
The type I element consists of a wired hole in a strip of
Deltamax tape. The type II element uses a stack of magnetic
tape instead of the Deltamax. The type III element...
Conventional register files spread porting resources uniformly across all registers. This paper proposes a method called Asymmetric Clustering using a Register Cache (ACRC). ACRC utilizes a fast register cache that concentrates valuable register file ports to the most active registers thereby reducing the total register file area and power consumption....
Because of its characteristics, the square-loop magnetic core
can be used as the basic device in a logic system. A magnetomotive
force (mmf) which is below the threshold mmf of such a core will
cause a negligible, nonpermanent amount of flux change in the core;
and information signals can be...
For gender-related information, previous studies have shown that children of
preschool age are more likely to remember schema-consistent information
over schema-inconsistent information. In this study, an attempt was made to
boost children's recognition for inconsistent information. In order to do this,
children were presented with pictures of both gender-consistent and...
Modern superscalar processors exploit instruction-level parallelism (ILP) by issuing multiple instructions in a single cycle because of increasing demand for higher performance in computing. However, stalls due to cache misses severely degrade the performance by disturbing the exploitation of ILP. Multiprocessors also greatly exacerbate the memory latency problem. In SMPs,...
Memory hierarchy design is becoming more important as the speed gap be- tween processor and memory continues to grow. Investigations of memory perfor- mance have typically been conducted using trace-driven emulation, which could take tremendous resources (e.g. long emulation time, large storage requirements for traces, and high overall cost). Recent...
Magnetic thin films have potential to improve devices such as on-chip inductors, and enable new technologies such as magnetic random access memory (MRAM).
The use of magnetic cores in on-chip inductors is typically limited to applications well under 1 GHz. At higher frequencies, the performance of the magnetic core is...
The study investigates the influence of the self-reference
effect upon the amount of main and subordinate ideas which older
adults can recall and recognize after viewing the television
documentary entitled, The Xinquana: Aborigines of South America.
The participants are native English-speaking Americans who are
50 years old or older. The...
Immunological memory has been shown to occur
unequivocally in mammals. However, controversy exists regarding
the capability of fish to elicite a memory response. This study
demonstrates that memory does occur
rainbow trout, Oncorhynchus rnykiss.
Trout injected with a T-dependent antigen,
trinitrophenylated keyhole-limpet hemocyanin, (TNP-KLH) (100
μg/fish) were able to produce...
Computers using the tagged-token dataflow model are among the best candidates for delivering extremely high levels of performance required in the future. Instruction scheduling in these computers is determined by associatively matching data-bearing tokens in a Waiting-Matching Unit (W-M unit). At the W-M unit, incoming tokens with matching contexts are...
As the aging population continues to grow worldwide, age-related complications are becoming more apparent within the aging population. One of the first age-related complications to become apparent is age-associated memory impairment and it can make the elderly more dependent on caregivers early on. The N-methyl-D-aspartate (NMDA) receptor is important to...
Resistive random access memory (RRAM) is a non-volatile memory technology based on resistive switching in a dielectric or semiconductor sandwiched between two different metals. Also known as memristors, these devices are potential candidates for a next-generation replacement for flash memory. In this thesis, bipolar resistive switching is reported for the...
As the aging population continues to grow the world over, age related complications become more and more apparent among the elderly population. One such complication is age associated memory impairment, which makes the elderly more dependent on caregivers early on. NMDA receptors in the brain are important for memory formation,...
The amount of instruction level parallelism (ILP) that can be exploited depends
greatly on the size of the instruction window and the number of in-flight instructions
the processor can support. However, this requires a register file with a large set of
physical registers for renaming and multiple ports to provide...
Memory is essential to everyday life. As we age, deficits in memory become apparent. The toll of age-related cognitive impairment can be devastating to families and costly to society. The NMDA receptor is a molecule in the brain that is instrumental in the formation of memories. The receptor is particularly...
The major limiting factor of DRAM access time is the low transconductance of the
MOSFET's which have only limited current drive capability. The bipolar junction
transistor(BJT) has a collector current amplification factor, β, times base current and is
limited mostly by the willingness to supply this base current. This collector...
Thin-film transistors (TFTs) are primarily used as a switching element in liquid crystal
displays. Currently, amorphous silicon is the dominant TFT technology for displays, but
higher performance TFTs will become necessary to enable ultra-definition resolution
high-frequency large-area displays. Amorphous zinc tin oxide (ZTO) TFTs were
fabricated by RF magnetron sputter...
