(University of Waterloo, 2019-05-30)Short-term travel time prediction supports the implementation of proactive traffic management and control strategies to alleviate if not prevent congestion and enable rational route choices and traffic mode selections to ... -
Simplified Seismic Design for Mid-Rise Buildings with Vertical Combination of Framing Systems
(University of Waterloo, 2016-01-11)The mid-rise building with vertical combination of framing systems consists of a structural system in which the seismic-force-resisting-system (SFRS) of the upper structure is commonly a lightweight structural system such ... -
Simulating the Effects of Enclosure Retrofits on Post-War High-Rise Apartment Buildings in Cold Climates
(University of Waterloo, 2011-08-31)A large portion of the existing building stock in North America is comprised of post-World War II high-rise apartment buildings, particularly in the Greater Golden Horseshoe in Ontario. They are home to a large portion of ... -
Simulation Modelling and Analysis of Impact of 3D Feedback Workflow on Prefabrication of Industrial Construction
(University of Waterloo, 2020-09-11)The construction industry has not been experiencing the same level of productivity increase as the manufacturing industry, due to their divergent production methods. While traditional construction projects are unique, ... -
Simulation of Cracks in a Cosserat Medium using the eXtended Finite Element Method
(University of Waterloo, 2013-02-15)This research investigates fracture behaviour in the Cosserat materials. The Cosserat elasticity description of the materials incorporates a characteristic length scale (e.g. grains, particles, fibres, etc.) into the model. ... -
Simulation of Hydraulic Stimulation: Acoustic Wave Emission in Fractured Porous Media Using Local and Global Partition-of-Unity Finite Element
(University of Waterloo, 2018-09-25)Hydraulic Fracturing (HF) is an effective stimulation process for extracting oil and gas from unconventional low-permeable reservoirs. The process is conducted by injecting high-pressure fluids into the ground to generate ... -
Simulation of Induced Acoustic Emission in Fractured Porous Media
(Elsevier, 2019-04-01)Acoustic/microseismic Emissions (AE) in naturally fractured porous media are the result of local instability along internal interfaces and the sudden release of strain energy stored in the rock matrix. This rapid release ... -
Simulation of multiple hydraulically driven fractures
(University of Waterloo, 2015-09-22)Hydraulic fracturing is a process that is used to release and extract natural gas from the pores of shale rocks. The process involves drilling vertical and horizontal wells through shale formation beds. After which, a ... -
Simultaneous nitrification, denitrification, and phosphorus removal at low temperatures
(University of Waterloo, 2022-05-10)Simultaneous nitrification, denitrification, and phosphorus removal (SNDPR) has been demonstrated to be a promising technology for carbon, nitrogen, and phosphorus removal. However, SNDPR has not been fully studied at low ... -
A Smartphone-based Connected Vehicle Solution for Winter Road Surface Condition Monitoring
(University of Waterloo, 2015-08-11)The monitoring of winter road surface conditions (RSCs) is essential to transportation agencies and the traveling public, since the former needs to be aware of the location and severity of existing RSCs in order to effectively ... -
Snow Accumulation in a Distributed Hydrological Model
(University of Waterloo, 2004)The cryosphere is defined as the portions of the earth where water is in solid form. It represents a very important part of the hydrologic cycle, affecting ecological, human and climate systems. A number of component ... -
The Socio-ecohydrology of Rainwater Harvesting in India: Understanding Water Storage and Release Dynamics at Tank and Catchment Scales
(University of Waterloo, 2016-05-02)Rainwater harvesting (RWH), the small-scale collection and storage of runoff for irrigated agriculture, is recognized as a sustainable strategy for ensuring food security, especially in monsoonal landscapes in the developing ... -
Sodium Chloride and Freezing Temperatures Increasing the Weathering of a Shale Bedrock Channel
(University of Waterloo, 2019-04-05)Studies on erodibility in shale channels attribute slaking as the primary weathering mechanism, and consider chemical weathering mechanisms as a secondary agent (Tinkler and Parish, 1998). This research examines the roles ... -
Soil-Structure Interaction Analysis of Monopile Foundations Supporting Offshore Wind Turbines
(University of Waterloo, 2018-08-07)Monopile foundations supporting offshore wind turbines are hollow circular steel piles of diameter 4-6 m and a slenderness ratio (length/radius) of 10-12 driven into the seabed in an average water depth of 35 m. They are ... -
Spatial and Temporal Trends in Water Quality in a Mixed-Use Landscape: Agriculture vs. Urban Areas
(University of Waterloo, 2018-10-22)The eutrophication of aquatic ecosystems is a growing water quality concern as it can promote the proliferation of harmful algal blooms that have severe environmental, health, and economic impacts. In United States alone, ... -
Spatial Decision Support System for Urban Streams
(University of Waterloo, 2017-09-27)The change of land use from rural to urban tends to radically alter the implicated streams with many symptoms of the “urban stream syndrome”. The key driver of the syndrome is hydrologic change; the product of increased ... -
