Modeling, Analysis, and Stabilization of a Single-Stage Utility-Scale Photovoltaic System with Reduced DC-Link Capacitance
DownloadFall 2020
A single-stage utility-scale photovoltaic (PV) system is usually interfaced with the host grid via a central voltage-source converter (VSC). Recently, due to their reliability, dc-link film capacitors are favored over electrolytic capacitors in grid-connected VSC applications. However, the...

Multinuclear Magnetic Resonance Tracking of Hydro, Thermal and Hydrothermal Decomposition of CH3NH3PbI3

Askar, A.,, Bernard, G.M, Wiltshire,, B., Shankar, K., Michaelis, V.K.
An NMR investigation of methylammonium lead iodide, the leading member of the hybrid organic-inorganic perovskite class of materials, and of its putative decomposition products as a result of exposure to heat and humidity, has been undertaken. We show that the 207Pb NMR spectra of the compound of...

Plant litter: direct and indirect effects of simulated climate change and clipping on its decomposition, and its effects on plant-plant interactions
DownloadFall 2013
Terrestrial ecosystems are characterized by an intricate relationship between plants and soils that influence ecosystem and community level processes and properties. At the ecosystem level, plants (producers) provide organic carbon to the decomposer subsystem and obligate root-associated...

Potential carbon losses from peat profiles: effects of temperature, drought cycles and fire
Download1992
Wein, R. W., Hogg, E. H., Lieffers, V. J.
Abstract: Global warming and the resultant increase in evapotranspiration might lead to lowered water tables in peatlands and an increase in fire frequency. The objective of this study was to investigate some of the potential effects of these changes on peat decomposition. Dry mass losses and...

Principal components of super-high dimensional statistical features and support vector machine for improving identification accuracies of different gear crack levels under different working conditions
Download2015
Tsui, Kwok Leung, Zuo, Ming J., Tse, Peter W., Wang, Dong
Gears are widely used in gearbox to transmit power from one shaft to another. Gear crack is one of the most frequent gear fault modes found in industry. Identification of different gear crack levels is beneficial in preventing any unexpected machine breakdown and reducing economic loss because...

Irving, B.D., Fedkenheuer, A.W., Bietz, J., Naeth, M.A., Lees, A.T.
Field sites for this study were established in 1987 shortly after the completion of construction of two pipelines in southern Alberta. The Dry Mixed Grass and Mixed Grass Ecoregions (Milo Pipeline Lateral) and the Aspen Parkland, Montane and Fescue Grassland Ecoregions (Porcupine Hills Lateral)...

Regulation of cold shock-induced RNA helicase gene expression in the cyanobacterium Anabaena sptrain PCC 7120
Download2000
Owttrim, George W., Chamot, Danuta
Expression of the Anabaena sp. strain PCC 7120 RNA helicase gene crhC is induced by cold shock.crhC transcripts are not detectable at 30°C but accumulate at 20°C, and levels remain elevated for the duration of the cold stress. Light-derived metabolic capability, and not light per se, is required...

Simulated Livestock Soil Compaction, Plant Defoliation and Litter Removal Effects on Extracellular Enzyme Activity and Vegetation Across a Moisture Gradient in Southern Alberta, Canada
DownloadSpring 2020
Barszczewski, Sara Janina Bodnar
Preservation of grasslands is vital for the continuation of the numerous ecosystem goods and services (EG&S) provided by these ecosystems, including forage for livestock, nutrient cycling, carbon sequestration and habitat for flora and fauna. All EG&S in grasslands are supported by microbial...

The biosphere as an increasing sink for atmospheric carbon: estimates from increased nitrogen deposition
Download1993
Estimates of carbon uptake and storage based on global nitrogen deposition, C:N ratios for typical terrestrial ecosystems, and recent ecosystem-scale nutrient studies indicate that 1.0- 2.3 Gt C yr-1 of carbon storage may be stimulated by anthropogenically caused increases in nitrogen deposition...

Landon, Stuart, Smith, Constance E.
The growth of debt and deficits in developed countries has led many states to consider the adoption of fiscal rules. There is little evidence on the benefits of different types of rules. This study uses Monte Carlo techniques to examine the impact on welfare and government spending stabilization...
