A study on probability of distribution loads based on expectation maximization algorithm (2017)
Conference Proceeding
Ganjavi, A., Christopher, E., Johnson, C. M., & Clare, J. C. (2017). A study on probability of distribution loads based on expectation maximization algorithm. doi:10.1109/ISGT.2017.8086037

In a distribution power network, the load model has no certain pattern or predicted behaviour due to large range of data and changes in energy consumption for end-user consumers. Thus, a powerful analysis based on probabilistic structure is required.... Read More

The ESO Diffuse Interstellar Bands Large Exploration Survey EDIBLES: I. Project description, survey sample and quality assessment (2017)
Journal Article
EDIBLES: I. Project description, survey sample and quality assessment. Astronomy and Astrophysics, 606, doi:10.1051/0004-6361/201730912. ISSN 0004-6361

The carriers of the diffuse interstellar bands (DIBs) are largely unidentified molecules ubiquitously present in the interstellar medium (ISM). After decades of study, two strong and possibly three weak near-infrared DIBs have recently been attribute... Read More

A new analysis for finding the optimum power rating of low voltage distribution power electronics based on statistics and probabilities (2017)
Conference Proceeding
Ganjavi, A., Christopher, E., Johnson, C. M., & Clare, J. C. (2017). A new analysis for finding the optimum power rating of low voltage distribution power electronics based on statistics and probabilities

The continuing trend toward heavier load and high penetration of Distribution Generation (DG) units in low voltage rural distribution feeders requires power electronic-based solution alternatives for voltage regulation purposes. The design of power e... Read More
