A Lagrangian Relaxation Approach to a Two-Stage Stochastic Facility Location Problem with Second-Stage Activation Cost
(University of Waterloo, 2012-05-18)We study a two-stage stochastic facility location problem in the context of disaster response network design. The uncertainty inherent in disaster occurrence and impact is captured by defining scenarios to reflect a large ... -
Lake Zooplankton Carbon Sources: The Role Of Terrestrial Inputs And The Effects Of Depth And Taxonomic Composition
(University of Waterloo, 2008-11-28)The relative contribution of allochthonous and autochthonous production in zooplankton nutrition has been of interest since the net heterotrophy of lakes was recognised to be common. I measured the 13C signature of ... -
Lakes of the Peace-Athabasca Delta: Controls on nutrients, chemistry, phytoplankton, epiphyton and deposition of polycyclic aromatic compounds (PACs)
(University of Waterloo, 2012-02-07)Floodplain lakes are strongly regulated by river connectivity because floodwaters exert strong influence on the water balance, the physical, chemical and biological limnological conditions, and the influx of contaminants. ... -
Laminar Separation Bubble Dynamics on a Finite Wing
(University of Waterloo, 2021-07-30)Laminar separation bubbles substantially influence the performance of finite wings at low chord Reynolds numbers. The objective of this study is to explore the influence of wingtip effects on three-dimensional laminar ... -
Land cover change analysis of Big Creek conservation area with satellite remote sensing
(University of Waterloo, 2013-08-20)Due to the relatively complex land cover configuration and a series of significant ecological implications, the issue of land cover changes in the Big Creek area are of critical value to environmental conservation groups, ... -
Land Cover Change and Climate on the North American Great Plains
(University of Waterloo, 2014-01-24)Changing land cover from prairie grasslands to intensive, primarily cereal agriculture, over the North American Great Plains since the mid-19th century, has had a hydrological and climatological impact on that ecosystem ... -
Land Disturbance Extraction in Alberta Oil Sands Satellite Imagery
(University of Waterloo, 2021-12-10)Tracking and mapping land disturbances from oil and gas development are critical to environmental assessments and land reclamation. Manual extraction of land disturbances is costly, time-consuming, and requires updating ... -
Land Tenure, Ecotourism, and Sustainable Livelihoods: 'Living on the Edge' of the Greater Maasai Mara, Kenya
(University of Waterloo, 2012-03-19)Since its introduction into mainstream society two decades ago, ecotourism has become an international phenomenon. Claimed by its proponents to endorse ecologically, socially, and economically sustainable travel to natural ... -
Land Use and Climate Influence Marshes in the Northern Prairie and Parkland Region
(University of Waterloo, 2016-01-21)I evaluated the association between waterbird communities and agricultural activity at 48 non-permanent wetlands, and waterbird response to inter-annual climate variation at 24 non-permanent wetlands. I found six distinct ... -
Land Use Change and Economic Opportunity in Amazonia: An Agent-based Model
(University of Waterloo, 2009-09-02)Economic changes such as rising açaí prices and the availability of off-farm employment are transforming the landscape of the Amazonian várzea, subject to decision-making at the farming household level. Land use change ... -
Land use changes and salinization: Impacts on lake phosphorus cycling and water quality
(University of Waterloo, 2023-09-05)Over the past few decades, there has been a rapid global increase in urbanization accompanied by the conversion of natural or agricultural land into more impervious land cover. This ongoing acceleration of global urbanization ... -
Land, Water, Waste and Air: Resource and Promise in the Informal City
(University of Waterloo, 2013-08-30)Striving for subsistence, the growing population of Caracas has radically transformed the city in the course of the past fifty years. The inability of the city to respond to the accelerated growth that resulted from mass ... -
Landscape analysis & boundary detection of bog peatlands’ transition to mineral land: The laggs of the eastern New Brunswick Lowlands, Canada
(University of Waterloo, 2014-04-29)The wet zone – the lagg – that tends to form at the edge of ombrotrophic peatlands is believed to play an important role in promoting and maintaining the health of bog systems. The lagg is well-recognized by peatland ... -
Landscape Connectivity Analysis for Conservation Planning in Southern Ontario
(University of Waterloo, 2024-01-02)The strategic planning of land conservation is a critical undertaking in urban/peri-urban areas. Natural areas in cities and their surroundings exist in an environment of competitive land use pressures, where the allocation ... -
Landscape Effects on Breeding Habitat Selection and Incubation Behaviour in Boreal Nesting Ducks
(University of Waterloo, 2021-04-26)Canada’s western boreal forest is the second most important breeding area for North American duck populations. Over the last several decades, this region has experienced a considerable expansion of industrial development ... -
Landscape Grammar
(University of Waterloo, 2002)The protection and enhancement of visual resources constitute an on-going challenge to the planning authorities in many communities. The crux of this challenge is to guide development towards built and natural landscape ... -
Landscapes in Motion: Active Aging in China
(University of Waterloo, 2018-09-26)Aging in China does not mean slowing down or losing flexibility. On the contrary, aging in China is about regaining youth and becoming a younger replica of oneself. Seniors are becoming more mobile and agile through various ... -
Landscope | Interpreting Environmental Consciousness
(University of Waterloo, 2008-07-04)This thesis proposes a way in which architecture and the built environment might work to integrate human consciousness and natural process. A theoretical design entitled Landscope is presented as a responsive, sustainable ... -
