Lagrange: A Three-dimensional Analytic Lens Design Method for Spectacles Application
(University of Waterloo, 2014-01-02)Purpose: traditional optical design is a numerical process based on ray tracing theory. The traditional method has the limitation of the application of the spectacle lens because of the necessity of initial configurations ... -
A Lagrangean Relaxation and A Heuristic for the Pooling Problem
(University of Waterloo, 2008-01-25)The pooling problem is one of the fundamental optimization problems encountered in the petroleum industry. In the pooling problem, final products are produced using two stages of blending operations. In the first stage, ... -
A Lagrangian Approach for The Airfreight Consolidation Problem Under Pivot-weight
(University of Waterloo, 2018-05-23)International airfreight forwarders are faced with the problem of consolidating ship- ments for efficient transportation by airline carriers. The use of standard unit loading devices (ULDs) is a solution adopted by the ... -
Lagrangian Flow Field Reconstruction Based on Constrained Stable Radial Basis Function
(University of Waterloo, 2023-04-27)Recent advances in three-dimensional (3D) high seeding density time-resolved Lagrangian particle tracking (LPT) techniques have made diagnosing fluid flows at high resolution in space and time under a Lagrangian framework ... -
A Lagrangian model for hardening behaviour of materials at finite deformation based on the right plastic stretch tensor
(Elsevier, 2010-05-01)In this paper a modified multiplicative decomposition of the right stretch tensor is proposed and used for finite deformation elastoplastic analysis of hardening materials. The total symmetric right stretch tensor is ... -
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. ... -
Lambda lysozyme, overexpression, ligand studies, and incorporation of trifluoromethionine

Laminar Free Convection from a Pair of Horizontal Cylinders: A Three-Temperature Problem
(2015-06)The formulation of multi-temperature convection problems in terms of a single driving temperature difference and a single heat transfer coefficient does not properly reflect the physics of the problem. Paired heat transfer ... -
Laminar natural convection heat transfer from isothermal horizontal cylinders with annular fins
(University of Waterloo, 1998) -
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 ... -
Laminated Injection Mould with Conformal Cooling Channels: Optimization, Fabrication and Testing
(World Academic Publishing, 2013-06-01)Conformal cooling channels follow the cavity shape and can provide a better cooling performance in injection moulds. Laminated tooling is one of the techniques for manufacturing injection moulds with conformal cooling ... -
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 ...
