Nonblocking Memory Refresh
… a century ago, DRAM has required dynamic/active refresh operations that block read requests and decrease performance. We propose refreshing DRAM in the background without stalling read accesses to refreshing memory blocks, similar to the static/background refresh in SRAM. Our proposed Nonblocking …

Refresh reduction in dynamic memories
… eDRAM, being a dynamic memory, requires periodic refresh, which ends up consuming substantial energy for large last-level caches. In upcoming architectures that stack a processor die and multiple DRAM dies, DRAM dies experience higher temperatures. Elevated temperatures increase the periodic …

Perceptual models for high-refresh-rate rendering
… substantial computational power. With new high-refresh-rate displays as well as the renaissance of virtual reality (VR) and augmented reality (AR), one cannot expect that GPU performance will scale fast enough to meet the requirements of immersive photo-realistic rendering with current rendering …

A CORE REFRESH COLOR DISPLAY SYSTEM FOR MINICOMPUTERS
A raster-scanned, color display system refreshed by recycling data stored in the core memory of a Digital Equipment Corporation PDP 8/E minicomputer is described in detail. The system, which makes use of the computer's Data Break facility, was tested on a monochromatic monitor but is capable of …

ASSESSING PERFORMANCE OF NCEP RAPID REFRESH MODEL TO PREDICT BOUNDARY LAYER PROPERTIES
… to explore meteorological forecasts (i.e. Rapid Refresh) to see if we can use them in the processing stream for aerosols. While the state of delay zero is assimilated, the following forecasts for large enough delay can be used to provide PBL integrated RH that can be used in modified aerosol …

Refrint: intelligent refresh to minimize power in on-chip multiprocessor cache hierarchies
… DRAM (eDRAM). However, such systems require refresh. In this paper, we examine the opportunity of minimizing on-chip memory power by intelligently refreshing a full-eDRAM cache hierarchy. We present Refrint, a simple approach to perform fine-grained, intelligent refresh of eDRAM …

Elementary Principals' Strategies For Managing The Educational Technology Refresh Process: A Case Study
… engaged in leading the educational technology refresh process. Data collected for this qualitative, multi-site, descriptive case study occurred between November 2008 and June 2009. The study explored the educational technology refresh planning strategies of five elementary principals. Study …

Refresh. Restriction For Reorganising Sleep Habit: A randomised controlled trial of simplified sleep restriction for primary insomnia in the primary care setting
Rationale: Insomnia is a common health problem for patients in primary care. A literature review conducted by the author concluded that cognitive behavioural therapy for insomnia (CBT-I) is effective but its use has been limited by the time and expense required for delivery. Sleep restriction, or …

SCALE DRAM subsystem power analysis
… derived values, and an analysis of the DRAM refresh requirements is performed. Some notable power consumption results include active powerdown being much closer to precharge powerdown and reads taking much less current than the datasheet indicates. In addition, based on the refresh tests, a …

Improved Techniques for Video Compression and Communication
… communication over wireless networks. Intra-refresh coding, which embeds intra coded regions into inter frames can achieve a relatively smooth bit-rate and terminate the error propagation caused by the transmission loss. In this dissertation, we propose a novel linear model for the …

Visual discrimination and object/picture recognition in hens
… discrimination to a CRT monitor at different refresh rates, on which the images were assumed to appear flickering. It was found that hens showed transfer across all refresh rates with coloured stimuli, but that the degree of transfer decreased as refresh rate decreased with stimuli that were …

Energy-efficient video decoding using data statistics
… banks spend 80% of their energy on frequent refresh operations to retain stored data retention. To reduce refresh energy, we compress the video data stored in the eDRAM by exploiting spatial correlation among pixels. Thus, unused eDRAM banks can be turned off to reduce refresh energy by 55%. …

Exploiting on-chip memory concurrency in 3d manycore architectures
… 3D memories and propose variable-rate per-bank refresh management that exploits variability in temperature to reduce 3D DRAM's refresh power and extend its operating range to higher temperatures.

Effects of Illumination and Viewing Angle on the Modeling of Flicker Perception in CRT Displays
… size, viewing distance, screen luminance, and refresh rate. Ten participants viewed different display sizes from different eccentricities under different levels of illumination and luminance. In each condition the display's refresh rate was manipulated using the Method of Limits to determine …

Field Dependent/independent College Undergraduates and the Usage of a Computer -Assisted Instruction Program in a Horticulture Class
… it's best usage may be to present recall cues to refresh their learning. In contrast, field dependent students did not feel there was benefit in using the CAI program, but with provided structure, benefits may occur. It would appear that the CAI program may be a good method of presenting recall …

GREMLIN: GOES radar estimation via machine learning to inform NWP
… to support the need for high-resolution rapidly refreshing imagery for situational awareness. Despite the well demonstrated value to human forecasters, usage of GOES imagery in data assimilation (DA) for initializing numerical weather prediction (NWP) has been limited, particularly in cloudy and …

Modeling and design of energy-efficient dependable memory sub-systems
… techniques to enable the exploitation of the refresh-by-access property of DRAM. We modify the scheduling order of accesses to the memory controller by re-ordering of the tasks in an application to minimize the duration of data residing in memory. This results eventually in decreased …

Assessing the Effects of Momentary Priming On Memory Retention During An Interference Task
… (momentary memory priming) was hypothesized to refresh the subjects' memory of the target words. 143 subjects, in a within subject design, were given a 33ms presentation of the target memory words during the interference task in a treatment condition and a blank 33ms presentation in the control …
