Neural mechanisms underlying the flexible and continuous allocation of visual short-term memory resources.
… whether objects stored in visual short-term memory (VSTM) are maintained as discrete items or as a continuous resource. While much recent behavioral evidence has supported a continuous resource model, neurological support has lagged behind. In the current study, participants underwent fMRI …

The Role of Working Memory Resources in Mind Wandering: The Difference Between Working Memory Capacity and Working Memory Load
… no consensus on the relationship between working memory resources and mind wandering. The purpose of the current study is to investigate whether mind wandering requires working memory resources to be sustained. The resource-demanding view is that mind wandering requires working memory resources to …

Functional dissociation between visual and spatial temporary maintenance
… dissociation between visual and spatial working memory systems by the use of dual-task interference methodology. Two temporary maintenance tasks that are putatively assumed to rely on visual and spatial memory resources respectively, i.e., retention of visual items (geometric forms or Chinese …

The association between anxiety and working memory and the effects on skill acquisition and transfer
… or interfering thoughts that impact on working memory resources resulting in performance deficits cognitive tasks. Furthemore, skill acquisition theories propose that working memory plays an important role in attentional processes during the initial stages of learning. The study investigates the …

The Neural and Psychological Constituents of Placebo and Distraction
… 1 provides evidence that overlapping cognitive resources are involved in both pain and executive attention and working memory. Study 2 provides evidence that these same executive attention and working memory resources are not involved in placebo analgesia, and that placebo analgesia and …

Interference control in language processing: the effects of age and working memory
… Older adults or individuals with less working memory capacity have often been reported to have more difficulties in binding individual concepts in a sentence to form an integrated representation of ideas (e.g., thematic roles assignment). In contrast, situation understanding or simulation of …

Development of a parallel SAR processor on a Beowulf cluster
… the data set being processed distributed in memory over the nodes in the cluster. This was successfully achieved using a in-place method, thus saving valuable memory resources. Once the parallel processor was implemented some timing tests were performed, yielding a maximum speedup factor of …

An Analysis of Intention Formation as a Function of Prospective Memory in Air Traffic Controllers
<p>Prospective memory, or memory for future intents, is an important part of everyone's daily life. Air traffic controllers whose jobs are based in an environment that taxes their memory resources for extended periods of time rely on this type of memory. Controllers objectives often change based on …

Embedded machine vision - a parallel architecture approach -
… model is proposed to estimate the required memory size and processing frequency. Next, custom architectures are designed with the considerations of optimising logic and memory resources. Specifically, the low pass filter, edge detection and thresholding algorithm are designed with the aim of …

Intra- and Inter-chip Communication Support for Asymmetric Multicore Processors with Explicitly Managed Memory Hierarchies
… nodes with high computing potential but limited memory resources. Instead of dividing very large data sets once among computation resources, Cell Connector slices, distributes, and collects work units off of a master data held by a single large memory machine. Using this methodology, Cell …

Acceleration of the noise suppression component of the DUCHAMP source-finder
… is the most computationally expensive and memory intensive within DUCHAMP and consequently improvements to it greatly improve overall DUCHAMP performance. We present a high performance, multithreaded implementation of the à trous algorithm with a focus on 'desktop' computing hardware to …

Optimizing Runtime Performance of Dynamically Typed Code
… Besides, the optimized code consumes fewer memory resources. The third optimization is focused on the improvement of multiple dispatch for object-oriented languages. One typical way of providing multiple dispatch is resolving method overload at runtime: depending on the dynamic types of the …

Relationships in Aging, Cognitive Processes, and Contingency Learning
… the influence of age, processing speed, working memory,and associative processes on the acquisition of contingency information. Young and older adults completed positive (+.65) and negative (-.65) contingency tasks that measured their ability to discover the relationship between a symptom (e.g., …

A region-based architecture for service-providing distributed systems
… such as data, content, computational and memory resources and data-based services to other entities in the system. Consumers that wish to use services describe their needs with a set of high-level objectives. In this thesis, we address the problem of locating services in a large-scale …

Predictable inter-core communication for strictly partitioned real-time multi-core systems
… to partition and regulate access to shared resources, such that multi-core processors can be deployed for safety-critical avionics applications. Strict partitioning of memory resources among cores, however, does not allow inter-core communication. In this paper, we propose a Communication …

Programming High-Performance Clusters with Heterogeneous Computing Devices
… leading to heterogeneity in the computation and memory subsystems. To program such systems, application developers typically employ a hybrid programming model of MPI across the compute nodes in the cluster and an accelerator-specific library (e.g.; CUDA, OpenCL, OpenMP, OpenACC) across the …

Digital predistortion of RF amplifiers using baseband injection for mobile broadband communications
… does not require large digital signal processing memory resources and computational complexity. Moreover, the injection-based DPD theory is extended to be applicable in concurrent dual-band wireless transmitters. A cross-modulation problem specific to concurrent dual-band transmitters is …

Pervasive handheld computing systems
… by their size, their computational power, their memory resources, their power usage, and their networking ability. These constraints challenge pervasive handheld computing systems in achieving their multi-functional and high-performance requirements. This thesis proposes a two-pronged methodology …

The effects of unconscious thought and domain familiarity on younger and older adults' decision making
… or a distracted condition in which their working memory resources were taxed for the same amount of time. In the decision phase, participants were then asked to immediately choose which of the two options provided the best value for money. Results indicated that overall older adults made better …

Working memory availability and quality control in children's production of passive sentences as novices
… OF MISSOURI AT AUTHOR'S REQUEST.] Working memory (WM) is widely accepted as a necessary cognitive resource for a vast amount of cognitive abilities. Developmental work has shown that as WM capacities increase, so too does the ability to successfully perform other cognitive tasks including …
