Spring 2012
The energy sector is moving towards extensive use of power electronic (PE) converters to interface distributed generation (DG) units and modern converter-interfaced loads (CILs). Therefore, the conventional distribution-grid is gradually transformed into a multi-stage PE converter-dominated...

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...

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...

Wishart, D.S., Neal, S., Berjanskii, M.V.
Every year between 500 and 1000 peptide and protein structures are determined by NMR and deposited into the Protein Data Bank. However, the process of NMR structure determination continues to be a manually intensive and time-consuming task. One of the most tedious and error-prone aspects of this...

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...

Quality aspen (Populus tremuloides Michx.) nursery seedlings are difficult to produce. In this thesis I explored methods to improve the nutrient status (loading) of aspen seedlings. Tissue nutrient concentrations doubled in seedlings treated with a shoot growth inhibitor (SGI) compared to...
