Circularly-Polarized Endfire Antenna and Arrays for 5G Millimetre-Wave Beamsteering Systems
Download2020-04-17
Al-Amoodi, Khaled, Honari, Mohammad Mahdi, Mirzavand, Rashid, Melzer, Jordan, Elliott, Duncan G., Mousavi, Pedram
This study presents a circularly-polarised substrate-integrated waveguide end-fire antenna and four-antenna arrays for 5G beam-steering mobile devices at 28 GHz. Polarisation is achieved through implementation of a substrate-integrated waveguide notched-septum polariser. It is then loaded with a...

Citizen Engagement in Sustainability Planning: Patterns and Barriers from Hinton and Wood Buffalo, Alberta, Canada
Download2019-01-01
Hallström, Lars K., Hvenegaard, Glen, Dipa, Susrat Jahan
Canada’s Gas Tax Fund is intended to support municipal sustainability initiatives, provided that each applying municipality formulates a form of Integrated Community Sustainability Plan. Both the federal and provincial governments made citizen participation an important requirement of the...

Clarifying the relationship between average excesses and average effects of allele substitutions
Download2012
Yang, Rong-Cai, Álvarez-Castro, José M.
Fisher’s concepts of average effects and average excesses are at the core of the quantitative genetics theory. Their meaning and relationship have regularly been discussed and clarified. Here we develop a generalized set of one locus two-allele orthogonal contrasts for average excesses and...

Purpose - This paper aims to respond to the 2005 paper by Hjorland and Nissen Pedersen by suggesting that an exhaustive and universal classification of the phenomena that scholars study, and the methods and theories they apply, is feasible. It seeks to argue that such a classification is critical...

Classifying Crystal Structures of Binary Compounds AB through Cluster Resolution Feature Selection and Support Vector Machine Analysis
Download2016
Adutwum, Lawrence A. , Harynuk, James, Mar, Arthur, Oliynyk, Anton O.
Partial least-squares discriminant analysis (PLS-DA) and support vector machine (SVM) techniques were applied to develop a crystal structure predictor for binary AB compounds. Models were trained and validated on the basis of the classification of 706 AB compounds adopting the seven most common...

Predictions for climate change include movement of temperature isoclines up to 1000 meters per year, and this is supported by recent empirical studies. This paper considers effects of a rapidly changing environment on competitive outcomes between species. The model is formulated as a system of...

Climate and nutrient influences on the growth of white spruce trees in the boreal forests of the Yukon
Download2008
Krebs, C.J., Boonstra, R., Desantis, L., Hik, D.S.
The boreal forests of North America are undergoing major changes because of the direct effects of global warming and increased CO2 levels. Plant production in the boreal forest is nutrient limited, and we examined how long-term fertilization affected growth of white spruce Picea glauca in the...

Many autecological effects of temperature on fish are known, and fishery biologists have begun to incorporate this knowledge into population-level relations that can be used to assess possible effects of climatic warming on fishes and their habitats. However, the problem of extrapolating these or...
