Forecasting Pavement Surface Temperature Using Time Series and Artificial Neural Networks
(University of Waterloo, 2008-06-19)Transportation networks play a significant role in the economy of Canadians during winter seasons; thus, maintaining a safe and economic flow of traffic on Canadian roads is crucial. Winter contaminants such as freezing ... -
Storey-Based Stability Analysis for Multi-Storey Unbraced Frames Subjected to Variable Loading
(University of Waterloo, 2008-07-23)For decades, structural engineers have been using various conventional design approaches for assessing the strength and stability of framed structures for various loads. Today, engineers are still designing without some ... -
Geomechanics-Reservoir Modeling by Displacement Discontinuity-Finite Element Method
(University of Waterloo, 2008-07-29)There are two big challenges which restrict the extensive application of fully coupled geomechanics-reservoir modeling. The first challenge is computational effort. Consider a 3-D simulation combining pressure and heat ... -
Automated Recognition of 3D CAD Model Objects in Dense Laser Range Point Clouds
(University of Waterloo, 2008-08-11)There is shift in the Architectural / Engineering / Construction and Facility Management (AEC&FM) industry toward performance-driven projects. Assuring good performance requires efficient and reliable performance control ... -
Torsion in Helically Reinforced Prestressed Concrete Poles
(University of Waterloo, 2008-08-22)Reinforced concrete poles are commonly used as street lighting and electrical transmission poles. Typical concrete lighting poles experience very little load due to torsion. The governing design loads are typically bending ... -
Flexural Behavior and Strength of Cold-formed Steel L-Headers
(University of Waterloo, 2008-08-25)Cold-formed steel framing of residential and light commercial buildings continues to grow in popularity due to its structural and material advantages. The North American steel industry is actively performing research ... -
Finite Element Studies of an Embryonic Cell Aggregate under Parallel Plate Compression
(University of Waterloo, 2008-08-25)Cell shape is important to understanding the mechanics of three-dimensional (3D) cell aggregates. When an aggregate of embryonic cells is compressed between parallel plates, the cell mass and the cells of which it is ... -
Strengthening of Wooden Cross arms in 230 kV Transmission Structures Using Glass Fibre Reinforced Polymer (GFRP) Wrap
(University of Waterloo, 2008-08-26)There are approximately 6000 Gulfport-type wood structures used to support 1600 km of 230 kV electrical transmission lines in Ontario. An unexpected structural failure caused by wood deterioration has been recognized as a ... -
Exploring Pretreatments for the Solar Water Disinfection (SODIS) Process
(University of Waterloo, 2008-08-27)The use of sunlight for water disinfection has been practiced since ancient times. Only in the last three decades has solar disinfection become widely recognized as a viable means of providing safe drinking water to the ... -
Evaluation and Quantification of Engineered Flocs and Drinking Water Treatability
(University of Waterloo, 2008-08-28)Jar tests are performed to simulate full-scale pre-treatment and particle removal processes. Operators typically conduct them in an effort to attempt alternative treatment doses and strategies without altering the performance ... -
Shear Behaviour of Disturbed Regions in Reinforced Concrete Beams with Corrosion Damaged Shear Reinforcement
(University of Waterloo, 2008-08-29)Corrosion of reinforcing steel is a major problem facing infrastructures owners with billions of dollars spent in repairing our aging infrastructure. One of the first steps in the repair process is to quantify the strength ... -
Vibration Serviceability and Dynamic Modeling of Cold-Formed Steel Floor Systems
(University of Waterloo, 2008-09-10)The use of cold-formed steel as a framework for floor systems in multi-story buildings and single occupancy residences is becoming an increasingly popular alternative to traditional materials and techniques. Builders and ... -
Evaluation of High Performance Residential Housing Technology
(University of Waterloo, 2008-09-11)The energy consumption of residential buildings in Canada accounts for 17% of national energy use (Trudeau, 2005). Production homes represent a considerable portion of new housing. In an effort to reduce the national ... -
