plant diversity effect on soil carbon dynamics
(2019)soil organic carbon (soc) is a valuable natural resource, supplying goods and services for human benefits, including mediating global climate change and securing food production and environmental quality. biodiversity loss ... -
attitude and position control of flapping-wing micro aerial vehicles
(2018)compared with the fixed-wing and rotor aircraft, the flapping-wing micro aerial vehicle is of great interest to many communities because of its high efficiency and flexible maneuverability. however, issues such as ... -
coordination chemistry of bithiazole ligands: a comparative study of the 2,2’ and 4,4’ isomers
(2019)the bithiazole ring system consists of two thiazole (c3ns) aromatic rings. there are many regioisomers but two of potential interest for coordination chemistry are the 2,2’-bis(1,3-thiazole) and the 4,4’-bis(1,3-thiazole), ... -
low-power multi-band injection-locked wireless receiver
(2019)the demand for low-power high-performance wireless receivers has dramatically in- creased with the emerging deployment of wireless sensor networks (wsns). among the demodulation schemes, non-coherent receivers consume ... -
increased production of sugar streams from lignocellulosic materials through enzyme recycling
(2019)the canadian pulp and paper mills generate over 1 million tons of primary sludge per year. this sludge mainly contains small cellulosic fibers and contaminants from pulp and paper manufacture and is usually disposed of by ... -
quadrotor altitude and attitude control with neural network
(2017)over the years, the controller design for an unmanned aerial vehicle has been attracting considerable amount of attentions and interests. in this thesis, a quadcopter has been studied intensively, and an adaptive ... -
learning through relationship: in-context development for teachers of indigenous 世界杯2022赛程表淘汰赛
(2019)in this study, i explore the experiences and qualities of productive learning relationships shared by indigenous and non-indigenous educators in k-12 public education contexts. i know from my own teaching experience and ... -
robust control techniques for dfig driven wecs with improved efficiency
(2019)wind energy has emerged as one of the fastest growing renewable energy sources since mid-80‘s due to its low cost and environmentally friendly nature compared to conventional fossil fuel based power generation. current ... -
phenology, growth and physiological responses to photoperiod and elevated [co2] of boreal white birch (betula papyrifera marsh): implications to climate change-induced northward migration
(2019)with the increase in average global temperature due to rising atmospheric carbon dioxide concentration ([co2]), rapid shifts of climate envelopes are expected to lead to norward migration for boreal tree species. as a ... -
development of nanostructured material based electrochemical sensors for food safety and quality control
(2019)the issue of foodborne related illnesses due to additives and contaminants poses a significant challenge to food processing industries. electrochemical-based strategies offer simple and robust analytical tools, which are ... -
reliability analysis of soil liquefaction using truncated distributions
(2019)soil liquefaction is a phenomenon caused by seismic activity in the ground which may result in surface settlement, the formation of sand boils, lateral spreading that ultimately damages the super-structure and loss of ... -
particle swarm optimization based adaptive neuro-fuzzy interference system for mppt control of a three phase grid connected photovoltaic system
(2019)there is a significant demand for renewable energy systems to ensure sustainable and environmentally friendly living. shifting from the use of fossil fuels to renewable energy sources will decrease both the reliance on ... -
diagnostic and treatment approaches to fibromyalgia management: quantification of peripheral blood mononuclear cell function and evaluation of radial shockwave therapy
(2019)fibromyalgia (fm) is a chronic pain disorder that affects many individuals worldwide. the lack of a definitive diagnostic method and highly successful treatment approaches make it an interesting area of research. in the ... -
constructing two-dimensional molecular networks on metal and semiconducting surfaces : a scanning tunneling microscopy study
(2019)the synthesis of two-dimensional organic nanostructures on metal and semiconducting surfaces is studied under ultra-high vacuum (uhv) conditions. three halogenated organic molecules are investigated using scanning tunneling ... -
simulation-based modelling of the unpaved road deterioration and maintenance program in heavy construction and mining sectors
(2019)saving cost is a significant factor in the successful operation of heavy civil engineering, such as highway and dam construction, and mining projects, which can be achieved through the reduction of operating costs in large ... -
experimental determination of the residual compressive strength of concrete columns subjected to different fire durations and load ratios
(2019)the superior thermal property of concrete associated to its great capability of thermally insulating the embedded reinforcing steel rebar is the main reason for the good behavior of reinforced concrete structural elements ... -
are individuals able to accurately report their own behaviour? an investigation of observer-respondent disparity of reported behaviours associated with social anxiety?
(2019)social anxiety is characterized by the powerful fear of negative evaluation from others and a high level of self-focused attention (sfa). in addition, socially anxious individuals often engage in a variety of anxiety-related ... -
well-spaced and free-growing: effects and interactions of ecosite and renewal treatments on regenerating stands in northwestern ontario
(2019)effective renewal of harvested stands in ontario is mandated in the crown forest sustainability act (cfsa 1994). properly prescribed silviculture leads to forested stands that are regenerated successfully, have predictable ... -
effects of species mixtures on fine root production in a young boreal forest
(2019)1. fine roots (< 2 mm) play a key role in terrestrial ecosystem processes. species diversity loss has been recognized as one of the primary global change drivers that can have profound negative effects on ecosystem ... -
residual damage in mixed hardwood stands after mechanized logging
(2019)research and data collection on the issues surrounding mechanized harvesting in mixed hardwood stands was gathered within the great lakes-st. lawrence forest region. the silviculture prescription for the stands studied ...
