Channel Estimation in TDD MU-MIMO Systems using Sub-Linear Sparse Signal Recovery Algorithms

Creator:: Barry, David G.
Abstract:: Massive Multiple-User Miltiple-Input Multiple-Output (MU-MIMO) wireless communication systems incorporate promising advanced strong technologies for upcoming 5G communications. To obtain some of the high spectrum and energy e ciencies bonuses brought by MU-MIMO systems, the ability to obtain Channel State information, especially on the receiver side (CSI), is important. To minimize...

Bacterioplankton in the Oregon upwelling system: distribution, cell-specific leucine incorporation, and diversity

Creator:: Longnecker, Krista
Abstract:: Marine bacterioplankton play an important role in global elemental cycles because they return carbon dioxide and nutrients to the biosphere as they reduce organic matter. Furthermore, marine bacterioplankton are not uniformly active, and subpopulations of the in situ community may be more or less active at any given time. Defining...

Structure and productivity of marine benthic diatom communities in a laboratory model ecosystem

Creator:: Wulff, Barry Lee
Abstract:: Effects of light intensity, exposure to desiccation, reduced salinity, and thermal elevation on the functional and structural characteristics of marine benthic diatom communities were investigated in a laboratory model ecosystem and a respirometer chamber. Measurements of biomass (dry weight and ash-free dry weight) and chlorophyll a were made for each...

Investigating the ecological role of cell signaling in free-living marine heterotrophic protists

Creator:: Hartz, Aaron J.
Abstract:: Phagotrophic protists are major consumers of microbial biomass in aquatic ecosystems. However, biochemical mechanisms underlying prey recognition and phagocytosis by protists are not well understood. We investigated the potential roles of cell signaling mechanisms in chemosensory response to prey, and in capture of prey cells, by a marine ciliate (Uronema...

An historical review of Kolb's formulation of experiential learning theory

Creator:: Hickcox, Leslie K. (Leslie Kay), 1951-
Abstract:: The central purposes of this study were to review the historical sources of David Kolb's formulation of experiential learning theory, and to determine the effect and application of Kolb's theory and Learning Style Inventory as reflected in the literature between 1971 and 1990. It was found that Kolb based his...

Creator:: Raju, Vadivukarasi, Rains, Jordan, Gates, Cooper, Luo, Wei, Wang, Xingfeng, Stickle, William F., Stucky, Galen D., and Ji, Xiulei
Abstract:: We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

Competitive interactions and resource partitioning between northern spotted owls and barred owls in western Oregon

Creator:: Wiens, J. David
Abstract:: The federally threatened northern spotted owl (Strix occidentalis caurina) is the focus of intensive conservation efforts that have led to much forested land being reserved as habitat for the owl and associated wildlife species throughout the Pacific Northwest of the United States. Recently, however, a relatively new threat to spotted...

Parker, David Bill.pdf

Creator:: Parker, David Bill
Abstract:: Data from the southern Cascade Mountains of Oregon has been collected for application in computer analysis of snowfields. Vegetation type, canopy cover, slope, aspect, insolation, and snowfield ground truth delineation are given consideration. In addition, a procedure for transferral of data onto Landsat imagery was derived.

Creator:: Wang, Xingfeng, Raju, Vadivukarasi, Luo, Wei, Wang, Bao, Stickle, William F., and Ji, Xiulei
Abstract:: Despite the considerable advances of deposition technologies, it remains a significant challenge to form conformal deposition on surface of nanoporous carbons. Here, we introduce a new ambient hydrolysis deposition method that employs and controls pre-adsorbed water vapor on nanoporous carbons to define the deposition of TiO₂. We converted the deposited...

Phosphorus physiology and environmental forcing of oceanic cyanobacteria, primarily Trichodesmium spp.

Creator:: White, Angelicque E.
Abstract:: The biological transformation of dinitrogen gas (N2) into combined forms(termed N2 fixation) by certain genera of oceanic cyanobacteria represents the largest incoming flux of nitrogen to the global ocean. As such, biological nitrogen fixation plays a significant role in the regulation of oceanic productivity and the export of carbon and...
