Abstract Streaming graph partitioning methods have recently gained attention due to their ability scale very large graphs with limited resources. However, many such do not consider workload and characteristics. This may degrade the performance of queries by increasing inter-node communication computational load imbalance. Moreover, existing workload-aware cannot consistently provide good as the...

Car crashes rank among the leading causes of death in the United States. Founded in 1947, the AAA Foundation in Washington, D.C. is a not-for-profit, publicly supported charitable research and education organization dedicated to saving lives by preventing traffic crashes and reducing injuries when crashes occur. Funding for this report was provided by voluntary contributions from AAA/CAA and th...

results the results showed that the average hr at resting, sitting (32℃ ± 0.1℃), and light workload (30℃ ± 0.1℃) were 78.52 ± 12.10, 69.74 ± 11.98, and 110.78 ± 17.91 beat/min, respectively. the average of ear canal temperature was estimated at 36.70℃ ± 0.36℃ for sitting workload and at 36.71℃ ± 0.27℃ light workload. conclusions the findings of this study illustrated that the average hr and the...

Commercial applications are an important, yet often overlooked, workload with significantly different characteristics from technical workloads. The potential impact of these differences is that computers optimized for technical workloads may not provide good performance for commercial applications, and these applications may not fully exploit advances in processor design. To evaluate these issu...

Signal salience was manipulated using configural and object displays to examine their effects on the performance, workload, and stress of vigilance. Improving performance and reducing the workload and stress of vigilance are crucial concerns. Signal salience improves performance and reduces stress, but to date there have been no salience manipulations using configural displays in a vigilance ta...

Airports are often a capacity-limiting constraint for the rest of the National Airspace System (NAS). A recent effort investigated methods to improve surface operations by supplying optimized scheduling and sequencing advisories for the Ground and Local controllers working at Air Traffic Control Towers. The tool is collectively known as the Spot and Runway Departure Advisor (SARDA). A series of...

Energy efficiency has become a very important concern for enterprise data centers due to the significant cost on electricity. To improve the energy efficiency of data centers, researchers and practitioners have proposed enormous work to reduce the energy consumption of data centers. Most of previous work focus on reducing the energy consumption of IT equipment; however, the power losses caused ...

With a large percentage of total system cost going to system administration tasks, ease of system management remains a difficult and important goal. As a step towards that goal, this dissertation presents a success story on building systems that are self-predicting. Self-predicting systems continuously monitor themselves and provide quantitative answers to What...if questions about hypothetical...
