Reducing deadline miss rate for grid workloads running in virtual machines: a deadline-aware and adaptive approach
… their throughput by reducing job deadline miss rate. Integration of the virtualization into the grid to deploy on-demand virtual machines for jobs in a way that is transparent to the end users and have minimum impact on the existing system poses a significant challenge. This involves the …

The effect of a lower-Body exoskeleton on physical and cognitive warfighter performance
… pace over obstacles while following a confederate, participants were subject to a dual-task cognitive test in which they answered radio calls and visually scanned for lighted targets. Cognitive load was varied through a secondary radio task and measured with a visual reaction time test and the …

Adaptive Energy Management Scheme in Real-Time Energy Harvesting Embedded Systems
… to schedule all the tasks with least deadline miss rate. The AFP scheme has a mean relative error of 6-10% which is much lower than exponentially weighted moving average (EWMA) algorithm with an error of 30%. The large difference in the error percentage between the two prediction algorithms is …

Cache Characterization and Performance Studies Using Locality Surfaces
… methods and find that none of them accurately reproduce an original trace's locality. We then combine a mathematical description of caches with our locality definition to create cache characterization surfaces. These new surfaces visually relate how references with varying degrees of …

Study and implementation of Wavelet-based video coding for dynamic transition environments
… Consequently, devices should be able to tolerate a wide variety of execution conditions and system or transition resource availability, all of which have the potential to vary unpredictably at run-time. Scalable, wavelet-based applications can form a large piece of the solution to this puzzle …

Maternal near miss audit in Metro West Maternity services
Background: A near miss occurs when a pregnant woman experiences a severe life threatening complication during pregnancy or up to 42 days after the end of the pregnancy and survives. The near miss rate is defined as the number of near misses per 1000 live births. In 2011, World Health Organization …

Accurate Low-Cost Methods for Performance Evaluation of Cache Memory Systems
… the sampled data not only to predict the mean miss rate of the cache, but also to provide an empirical estimate of its actual distribution. A model is proposed to statistically project the results to different context-switch intervals from only one simulation of a small number of samples of a …

A non-coherent ultra-wideband receiver : algorithms and digital implementation
… is an emerging technique for wireless transmission in the 3.1-10.6 GHz unlicensed band with signal bandwidths of 500 MHz or greater. A non-coherent receiver based on energy collection reduces complexity, cost, and power consumption at the cost of channel spectral efficiency. The receiver …

Cache optimizations for stream programs
… set of transformations that either reduce cache-miss rate or reduce the number of memory accesses for the class of streaming applications, which are becoming increasingly prevalent in embedded, desktop and high-performance processing. A fully automated optimization algorithm is presented that …

Resource management in sensing services with audio applications
… resource-awareness to support high data-rate sensing modalities such as audio/video. This work therefore investigates the resource management problem in sensing services, with application in audio sensing. First, a modular, data-centric architecture is proposed as the framework within …

The Effects of Alarm System Errors on Dependence: Moderated Mediation of Trust With and Without Risk
… signaling systems suggests that false alarms and misses affect operator dependence via two independent psychological processes, hypothesized as two types of trust. These two types of trust manifest in two categorically different behaviors: compliance and reliance. The current study links the …

A machine vision approach to rock fragmentation analysis
[pp. i - iv missing] This thesis is concerned with the development of an instrument for the purpose of performing online measurement of rock size distribution using machine vision. This instrument has application in the gold mining industry where it could be used to measure the fragmentation of …

Locality-aware cache hierarchy management for multicore processors
… multicore processors and applications will operate on massive data with significant sharing. A major challenge in their implementation is the storage requirement for tracking the sharers of data. The bit overhead for such storage scales quadratically with the number of cores in conventional …

A Comparison of Microarray Analyses: A Mixed Models Approach Versus the Significance Analysis of Microarrays
DNA microarrays are a relatively new technology for assessing the expression levels of thousands of genes simultaneously. Researchers hope to find genes that are differentially expressed by hybridizing cDNA from known treatment sources with various genes spotted on the microarrays. The large number …
