Adaptive and phenotypic responses of white birch provenances to climate variations
(2009)Trees have adapted to their local climate, but with changes in the climate may currently, or in the near future occupy climates that are sub-optimal for growth and survival. The goal of current reforestation is therefore ... -
Adaptive backstepping control of quadrotors with neural-network
(2018)A quadrotor is a type of unmanned aerial vehicles. It has been widely used in aerial photography. The quadrotor has the capability of vertical takeoff and landing, which is very useful in small or narrow areas. The ... -
The adaptive cycle of meaning making: development and preliminary evaluation of a self-report scale
(2021)Meaning in life has long been established as a core component of individual well-being, making it a topic of great importance within psychological research. Advancements in psychological studies of meaning in life are ... -
Adaptive habitat selection by a single celled alga?
(2014-01-22)Faculty and students in the Department of Biology are bound together by a common interest in explaining the diversity of life, the fit between form and function, and the distribution and abundance of organisms. The research ... -
An adaptive neuro-fuzzy controller for vibration suppression of a flexible structure in aerial refueling
(2022)Air-to-air refueling (AAR) has been commonly used in military jet applications. Recently, civilian applications of AAR have been garnering increased attention due to the high cost of air travel, which is largely dictated ... -
Adaptive steady-state analysis of circuits using wavelets
(2021)This thesis presents research into utilizing the sparse representations of waveforms that are possible in the wavelet domain to increase the computational efficiency of the steady-state analysis of electric circuits. The ... -
Adaptive variation of trembling aspen in Northwestern Ontario
(2015-08-05)To demonstrate the pattern of adaptive variation of Populus tremuloides (Michx.) to northwestern Ontario climate conditions, a statistical analysis was completed of growth and phenology variables from 26 provenances. ... -
Adding time-series data to enhance performance of naural language processing tasks
(2023)In the past few decades, with the explosion of information, a large number of computer scientists have devoted themselves to analyzing collected data and applying these findings to many disciplines. Natural language ... -
Addressing Indigenous community concerns of lake health by assessing water quality in Constance Lake, ON and biomarker responses in freshwater mussels, Pyganodon grandis and Lampsilis siliquoidea
(2023)Constance Lake First Nation has had concerns regarding the health of a culturally significant lake, Constance Lake, for several years. There are several external stressors to this lake including urbanization and forestry, ... -
Adipose tissue remodeling in response to corticosterone and β3-adrenergic receptor agonist mirabegron
(2022)With the rise of metabolic diseases including obesity and type 2 diabetes, the need to investigate one of the most dynamic endocrine organs is critical for combating these diseases. Adipose tissue (AT) exists predominantly ... -
Admixtures for use in geopolymers
(2012-11-10)This study examined two novel approaches for the geopolymerisation of fly ash produced at thermoelectric power stations by combustion of coal. The first approach involved the use of cullet, a post-consumer glass waste, to ... -
Adsorption and microflotation studies with pure minerals and an arylhydroxamic acid collector
(2009)A study was conducted to understand the adsorption of N-hydrocinnamoyl-N-phenylhydroxyl-amine (HCNPHA) on the surfaces of various pure minerals: sphalerite, pyrite, galena, chalcopyrite and quartz. HCNPHA is a member of ... -
Adult Attention-Deficit Hyperactivity Disorder (ADHD) and the isolation of low and high end component operations in temporal processing and time perception
(2009)Evidence has shown that Attention-Deficit Hyperactivity Disorder (ADHD) is associated with deficits in temporal processing and time perception (Toplak & Tannock, 2004). Current literature, however, focuses on time perception ... -
Advanced deep regression models for smart operation of the oil and gas industry
(2023)The first industrial revolution in the early 18th century largely exploited steam power to replace animal labor. Since then, there has been rapid development in industrial operations. Now, the world has come to the brink ... -
