Dynamic bandwidth allocation in CDMA-based passive optical networks
(2014-12-18)Fiber to the home (FTTH) technology is an attractive solution for providing high bandwidth from the Central Office (CO) to residences and small-and medium-sized businesses. The emergence of Internet Protocol-based communication ... -
Dynamic bandwidth allocation in WiMAX broadband networks
(2012-11-10)Wireless communication networks have experienced remarkable growth in recent years and are becoming attractive alternative to cable and DSL in providing last mile network access. Candidate wireless technologies should be ... -
Dynamic bandwidth scheduling and burst construction algorithm for downlink in (4G) mobile WiMAX networks
(2014-01-22)Advanced wireless systems, also called fourth generation (4G) wireless systems, such as Mobile Worldwide interoperability for Microwave Access (WiMAX), are developed to provide broadband wireless access in true sense. ... -
Dynamic modeling and analysis of circumferential and spiral waves in piezoelectric cylinders
(2012)Understanding the dynamic characteristics of ultrasonic guided wave in structures is important, as it is one of the methods that are widely used in many different areas of industrial sectors and inspections, such as ... -
Dynamic resource allocation algorithms for long term evolution (LTE) wireless broadband networks
(2014-01-22)Following the successful standardization of High-Speed Packet Access (HSPA), the 3rd Generation Partnership Project (3GPP) recently specified the Long Term Evolution (LTE) as a next generation radio network technology to ... -
Dynamic stability of an axially loaded elastically restrained column
(2023)The dynamic stability of axially loaded columns is a key problem in structural analysis, and in earthquake engineering particularly. Experience has shown that columns occasionally buckle when subject to dynamic axial ... -
Dynamic stability of axially loaded beams on elastic foundations
(2019)Beams on elastic foundations have received great attention of researchers for its importance in civil engineering. The present work can be applied, for example, to the study of dynamically loaded finite columns which are ... -
Dynamic stability of piles under earthquake with fractional damping foundation
(2023)Pile foundation is an essential structural component in civil engineering. The failure of a pile foundation under an earthquake may result in significant economic consequences, such asinterruption of transportation, ... -
Dynamics of single axle rail wheelsets incorporating profiled wheels and rails
(2009)This thesis presents the theories and numerical simulations in regard to the behaviour of a single-axle railway wheelset commonly used in cargo rail cars. Specifically, creep forces, dynamic models, real wheel-rail profiles, ... -
E/raced : aboriginal youth identities and schooling
(2009)This qualitative study investigates Aboriginal high school students' negotiation of identity and identifying with school and community in relation to other representations. Within the literature, cultural and racial ... -
Early evidence of maize (Zea mays ssp. mays) and beans (Phaseolus vulgaris) on the northern plains : an examination of Avonlea cultural materials (AD 300-1100)
(2013-02-03)The goal of this thesis is to reconstruct the plant component of paleodiet for the Avonlea complex (AD 300 – 1100 BP), an early ceramic-producing culture on the Northern Plains. Avonlea peoples have been assumed by ... -
Early growth responses of black spruce seed sources selected for reforestation under climate change scenarios in Ontario
(2014)Study area : Northern boreal forest: (Northeastern - Sault Ste. Marie region) ; (Northwestern : Dryden and Kakabeka regions) -
Eco-arts Education: Developing a Connection with the Natural World through Yoga and Mindfulness
(2016)This research studies how yoga and mindfulness, in an outdoor setting, helps elementary students connect to and understand the natural world. The four interrelated spheres of holistic development created as the conceptual ... -
Ecological Concept Development at the Elementary School Level
(2012)This case study of one school was designed to examine the level of knowledge and understanding elementary students (ages 9 – 13) have for key ecological concepts that are found in the Ontario 2007 science curriculum ... -
Ecological implications of the 18th and 19th century fur trade: a study of five HBC post's accounts
(2016)This research critically addresses the ecological implications of the 18th and 19th Century fur trade and whether primary source material written and maintained by European fur traders can measure resource procurement ... -
Ecological niche modelling : salix in Ontario
(2013-04-10)It has long been recognized that organisms exist in environments peculiar to taxa. Climate is thought to be of primary importance in determining the natural geographic distribution of species. Growing concern over climate ... -
Economic analysis of vegetation management alternatives in Ontario
(2014-01-22)Vegetation management practices have become an integral component of forest management. Economics of alternative vegetation management treatments were analyzed in this thesis on the basis of two journal papers. Six research ... -
The economic feasibility of replacing diesel with renewable energy resources in remote First Nation communities in Northern Ontario
(2017)Ontario has many First Nation communities in the remote northern region that use diesel fuel to generate part or the whole of their energy requirements. There is a huge financial and environmental cost associated with ... -
Ecophysiological responses of black spruce (Picea mariana) seedlings to nutrient supply, N-P-K ratio and photoperiod at current and elevated CO2 concentration
(2012-11-10)The relationship between plant growth and nitrogen supply is frequently used in growth models to predict growth performance under global climate change scenarios. However, the relationship may be changed under elevated ... -
