Understanding Youth Transition as 'Becoming': Identity, Time and Futurity
(Elsevier, 2009-11-01)Drawing on recent work in psychology, philosophy, and youth geographies, this article responds to calls for theoretical rigour in children's geographies by developing the concept of becoming for youth transitions research. ... -
Upsampling Indoor LiDAR Point Clouds for Object Detection
(University of Waterloo, 2023-05-24)As an emerging technology, LiDAR point cloud has been applied in a wide range of fields. With the ability to recognize and localize the objects in a scene, point cloud object detection has numerous applications. However, ... -
Urban Growth and LULC Change Dynamics Using Landsat Record of Region of Waterloo from 1984 to 2013
(University of Waterloo, 2014-02-20)Frequent human activities resulted by rapid urbanization lead to a variety of urban-related environmental and socio-economic issues. Therefore, for effective environmental management and urban planning, monitoring urban ... -
Urban Regeneration through Public Space: A Case Study in Squares in Dalian, China
(University of Waterloo, 2004)Urban regeneration has been accompanying urban development since the earliest human settlement, and was emphasized after the World War Two. Several decades' experience and billions of dollars forced the decision makers ... -
Urban Roadside Tree Inventory Using a Mobile Laser Scanning System
(University of Waterloo, 2016-10-11)the road environment. Thus, effective methods are needed for the MLS data processing. The main goal of this thesis is to establish a feasible workflow by testing a series of methods to extract geometrical information of ... -
Urban Tourism: Global-Local Relationships in Dalian, China
(University of Waterloo, 2007-02-19)China used to impress the outside world as a country that was focused on its own development with few links to the rest of the globe. However, things have changed and now China is an increasingly important global player. ... -
The use of a filter product to remove phosphorus from surface runoff in agricultural fields
(University of Waterloo, 2021-09-28)Nutrient losses from agricultural fields are the largest sources of phosphorus (P) entering the Great Lakes in North America. Research has suggested that multiple conservation practices (CPs) used together (stacked) are ... -
Using a hierarchy of climate models to investigate snow processes influencing surface albedo
(University of Waterloo, 2017-08-16)Northern Hemisphere (NH) extratropical land has experienced dramatic warming over the past century, a trend that is expected to continue in the coming decades. There is however, significant uncertainty surrounding projections ... -
Using Geographic Relevance (GR) to contextualize structured and unstructured spatial data
(University of Waterloo, 2019-09-12)Geographic relevance is a concept that has been used to improve spatial information retrieval on mobile devices, but the idea of geographic relevance has several potential applications outside of mobile computing. Geographic ... -
Using GIS and Remote Sensing Techniques for Solar Panel Installation Site Selection
(University of Waterloo, 2013-09-27)Solar energy replacing conventional non-renewable energy has been widely implemented around the world. Currently, one of the most challenging problems is how to improve the efficiency of producing solar energy. Before ... -
