The Potential use of SIFT-MS as a breath diagnostic tool
(2009)The measurement of volatile chemicals in human breath has recently emerged as a non-invasive technique with the potential for the early diagnosis of disease. A benefit of early diagnosis is that treatment plans including ... -
The Correlations and the power characteristics of special classes of binary sequences for multicarrier communications
(2009)In recent years, multicarrier communication has attracted considerable attention as a promising technology that enables transmission of high data rates. One of major drawbacks of multicarrier communications is the high ... -
Location-independent packet scheduling for wireless EPON
(2009)Ethernet Passive Optical Network (EPON) is the latest access technology, based on IEEE standards, utilizing an optical network architecture optimized for simple, economical delivery of voice, data, and video over native ... -
Mobile ontology-based reasoning and feedback health monitoring system
(2009)As medical technology has developed over the past few decades, the average human life-span has increased and as a side effect, chronic illness has become more prevalent. Many patients now require constant, everyday monitoring ... -
Management, environmental and energy considerations for woodwaste
(2009)Manufacturing operations that process raw wood, such as sawmills and pulp and paper mills, generate wood residue, such as woodwaste, sawdust, shavings, wood chips and off-cuts, also known as woodwaste. The decomposition ... -
Catalytic gasification of biomass for the production of syngas with reduced tar formation
(2009)With increased concerns over greenhouse gas emission and decreasing fossil fuel supplies, biomass is increasingly seen as an alternative option for energy and chemical production. There are several technologies available ... -
Autonomous navigation algorithms for indoor mobile robots
(2009)In many autonomous mobile robotic applications, the capability of finding a good path is of primary importance, especially for the places which are cluttered by random obstacles that may appear on the robot's path. -
Identification of boreal mixedwood forest structure cohorts in Northwestern Ontario using Ontario's forest resource inventory, Abitibi-Bowater's continuous forest inventory and stepwise discriminant function analysis
(2009)A model was developed to determine if Ontario's Forest Resource Inventory (FRI) could be used to classify boreal mixedwood stands in northwestern Ontario into structural cohorts as proposed in the Multi Cohort Forest ... -
Fine root dynamics for three distinct Northern Ontario forests : a comparison of approaches used to estimate fine root biomass, productivity, and turnover
(2009)There is increasing interest to develop quantitative approaches to carbon accounting and determine carbon sequestration potential at both the site and landscape scales. Currently, our lack of understanding of fine root ... -
Fish biomonitoring in an industrial environment : the Toxicity Early Warning System (TEWS)
(2009)Industrial, agricultural and municipal effluent discharge into receiving waters continues to be a significant environmental problem. Currently, industrial effluent quality is assessed using chemical assays or by evaluating ... -
Establishing the test-retest reliability and concurrent validity of the repeat ice skating test in adolescent boys ice hockey players
(2009)This study examined the test-retest reliability and concurrent validity of the Repeat Ice Skating Test (RIST). This was an on-ice field anaerobic test that measured average peak power. It was validated with 3 anaerobic lab ... -
A Tunable high-static-low-dynamic-stiffness isolator and a fuzzy-neural network based active control isolator
(2009)Excessive vibration can be detrimental to a wide variety of structures and machines. Vibration isolation is an effective means to suppress vibration. This study focuses on development of some new techniques to improve ... -
An Assessment of adherence to treating tobacco use and dependence clinical practice guidelines in First Nations primary health care settings in Northwestern Ontario
(2009)The purpose of this study was to determine the extent to which tobacco clinical practice guidelines are followed by nurses within 22 primary health care settings in First Nations communities in Northwestern Ontario and to ... -
Selecting locations for forest fuel treatments using simulation optimization
(2009)Wildfires in the Canadian boreal forest poses a considerable threat to forest inventory, structures and human lives. Traditional reactive methods of fire suppression fail to mitigate this threat and can worsen the problem ... -
Nesting dynamics of the scarlet ibis (Eudocimus ruber) in Trinidad, West Indies
(2009)The effect of human disturbance on colonial waterbirds is a global issue. Many colonial waterbirds are migratory, and their protection depends on balancing conservation of their habitats and habits across many regions. ... -
Understory species response to partial harvesting in boreal riparian buffers
(2009)In order to preserve valuable riparian functioning, forest harvesting in Canada attempts to protect riparian areas through the application of a no-harvest buffer zone around water bodies, and more recently through the ... -
Context aware services for smart learning environments
(2009)This thesis describes a cost-effective infrastructure and implementation for building ubiquitous learning spaces. It uses techniques from the semantic web and ubiquitous computing to build a learner-centric service-based ... -
Carbon dynamics of boreal mixedwoods in central Canada
(2009)Large amount of carbon (C) stored in boreal forest ecosystems plays an important role in the global carbon cycle. Forest ecosystem C is stored in four major pools: live vegetation (above-and below ground), dead woody ... -
Through gendered lenses : exploring rural seniors' use of photovoice to document health barriers and supports in Northwestern Ontario
(2009)In recent years the popularity of visual research methods such as photovoice has steadily increased (Dennis et al., 2009). The knowledge that "images evoke deeper elements of human consciousness than do words" (Harper, ... -
Differences between the Francophone and Anglophone ethno-linguistic groups in the home care setting of Ontario
(2009)Although Francophones in Ontario represent the largest population of French-Canadians outside Quebec, little is known about this population, and especially about the older members of this ethno-linguistic group. The scarce ...
