The Signal Data Explorer: A high performance Grid based signal search tool for use in distributed diagnostic applications

We describe a high performance Grid based signal search tool for distributed diagnostic applications developed in conjunction with Rolls-Royce plc for civil aero engine condition monitoring applications. With the introduction of advanced monitoring technology into engineering systems, healthcare, etc., the associated diagnostic processes are increasingly required to handle and consider vast amounts of data. An exemplar of such a diagnosis process was developed during the DAME project, which built a proof of concept demonstrator to assist in the enhanced diagnosis and prognosis of aero-engine conditions. In particular it has shown the utility of an interactive viewing and high performance distributed search tool (the Signal Data Explorer) in the aero-engine diagnostic process. The viewing and search techniques are equally applicable to other domains. The Signal Data Explorer and search services have been demonstrated on the Worldwide Universities Network to search distributed databases of electrocardiograph data

A Binary Neural Network Framework for Attribute Selection and Prediction

In this paper, we introduce an implementation of the attribute selection algorithm, Correlation-based Feature Selection (CFS) integrated with our k-nearest neighbour (k-NN) framework. Binary neural networks underpin our k-NN and allow us to create a unified framework for attribute selection, prediction and classification. We apply the framework to a real world application of predicting bus journey times from traffic sensor data and show how attribute selection can both speed our k-NN and increase the prediction accuracy by removing noise and redundant attributes from the data

2015 U.S. Transgender Survey: Report on the Experiences of American Indian and Alaska Native Respondents

This report highlights the specific experiences of transgender American Indians and Alaska Natives in many areas of life. It builds upon NCTE's groundbreaking 2015 U.S. Transgender Survey—the largest ever survey of transgender people in the nation, with nearly 28,000 respondents.Findings from the full USTS report revealed the disturbing patterns of discrimination and mistreatment that transgender people in the survey faced. These experiences were amplified for transgender people of color, including transgender American Indians and Alaska Natives, who faced deeper and broader forms of mistreatment in many of the most basic elements of life

Geodynamic implications for zonal and meridional isotopic patterns across the northern Lau and North Fiji Basins

We present new Sr-Nd-Pb-Hf-He isotopic data for sixty-five volcanic samples from the northern Lau and North Fiji Basin. This includes forty-seven lavas obtained from forty dredge sites spanning an east-west transect across the Lau and North Fiji basins, ten ocean island basalt (OIB)-type lavas collected from seven Fijian islands, and eight OIB lavas sampled on Rotuma. For the first time we are able to map clear north-south and east-west geochemical gradients in 87Sr/86Sr across the northern Lau and North Fiji Basins: lavas with the most geochemically enriched radiogenic isotopic signatures are located in the northeast Lau Basin, while signatures of geochemical enrichment are diminished to the south and west away from the Samoan hotspot. Based on these geochemical patterns and plate reconstructions of the region, these observations are best explained by the addition of Samoa, Rurutu, and Rarotonga hotspot material over the past 4 Ma. We suggest that underplated Samoan material has been advected into the Lau Basin over the past ∼4 Ma. As the slab migrated west (and toward the Samoan plume) via rollback over time, younger and hotter (and therefore less viscous) underplated Samoan plume material was entrained. Thus, entrainment efficiency of underplated plume material was enhanced, and Samoan plume signatures in the Lau Basin became stronger as the trench approached the Samoan hotspot. The addition of subducted volcanoes to the Cook-Austral Volcanic Lineament material, first from the Rarotonga hotspot, then followed by the Rurutu hotspot, contributes to the extreme geochemical signatures observed in the northeast Lau Basin

Effects of Oil Field Brines on Biological Integrity of Two Tributaries of the Little Muskingum River, Southeastern Ohio

Author Institution: Department of Biology and Department of Geology, The University of AkronTwo headwater tributaries of the Little Muskingum River were compared to assess possible effects of oil field brines on biological integrity of the streams. Diatom, macroinvertebrate, and fish communities were analyzed during the summer, 1990, for possible changes in community-structure caused by brines. Dissolved chemicals associated with brines and natural surface waters were quantified monthly between May and October, 1991. Cranenest Fork, with a lower density of wells producing brines than Straight Fork, had a slightly more integrated benthic macroinvertebrate community and lower proportions of salt-tolerant diatoms. Twelve of fifteen measures of benthic macroinvertebrate community structure were consistent with expected effects of greater brine enrichment in Straight Fork. Both streams, however, conformed to benthic macroinvertebrate criteria for protection of aquatic life established in Ohio Water Quality Standards. The major difference between streams was the larger (13:1) percentage of salt-tolerant diatoms such as Navicula salinarum,Navicula tripunctata, andNavicula viridula v. avenacea in Straight Fork than in Cranenest Fork. Fish communities were similar between streams

Trusted CI Experiences in Cybersecurity and Service to Open Science

This article describes experiences and lessons learned from the Trusted CI project, funded by the US National Science Foundation to serve the community as the NSF Cybersecurity Center of Excellence. Trusted CI is an effort to address cybersecurity for the open science community through a single organization that provides leadership, training, consulting, and knowledge to that community. The article describes the experiences and lessons learned of Trusted CI regarding both cybersecurity for open science and managing the process of providing centralized services to a broad and diverse community.Comment: 8 pages, PEARC '19: Practice and Experience in Advanced Research Computing, July 28-August 1, 2019, Chicago, IL, US

Benthic Macroinvertebrates as Indexes of Water Quality in the Upper Cuyahoga River

Author Institution: Department of Biology and Center for Environmental Studies, The University of AkronThe upper Cuyahoga River in northeastern Ohio is the major source of domestic water for the City of Akron, an important recreational area, and a designated Ohio Scenic River. Indexes of water quality based on benthic invertebrate community composition indicate a wide range in water quality along the river, but overall water quality is relatively high compared to areas of the Cuyahoga River below Akron and to most nearby river systems. Highest quality areas are located in the most headwater region and in the lowermost region near Lake Rockwell. These areas are characterized by a large number of taxa (>50), moderate density of organisms (= 2,000/m2), high ratios of scraper-grazers to detritivores (>0.5), high ratios of amphipods to isopods, and less than 1% organic pollution-tolerant organisms. Moderate degradation of water quality due to organic sedimentation in these areas is indicated by large proportions of organic pollution-facultative organisms (27-66%), especially a great variety of chironomids. Lowest quality areas occur 1-2 km below waste water outfalls from small villages and below groups of rural streamside dwellings. These areas are characterized by up to 62% fewer species, very low ratios of amphipods to isopods (usually <2), and large proportions of organic pollution-facultative and tolerant organisms (43-95%), especially chironomids and oligochaetes
