On Occupancy Based Randomized Load Balancing for Large Systems with General Distributions
(University of Waterloo, 2019-11-13)Multi-server architectures are ubiquitous in today's information infrastructure whether for supporting cloud services, web servers, or for distributed storage. The performance of multi-server systems is highly dependent ... -
Scalable Surfaces for Electromagnetic Energy Harvesting and Wireless Power Transfer
(University of Waterloo, 2019-10-31)The idea of collecting electromagnetic (EM) energy and converting it into various forms of useful power dates back to the early 20th century. Nikola Tesla's wireless power transfer experiments demonstrated the concept ... -
Evaporation of Liquid Wall Film in Direct Injection Spark Ignition Engine-like Conditions
(University of Waterloo, 2019-10-30)The liquid wall film formed by the spray impingement in Direct Injection Spark Ignition (DISI) engines can directly produce a large amount of Particle Matter (PM) emissions. The PM emissions can be tremendously reduced if ... -
Coupled Dynamics of Cable-Harnessed Structures: Experimental Validation
(American Society of Mechanical Engineers, 2019-07-15)The experimental study and model validations for the coupled dynamics of a cable-harnessed beam structure are presented. The system under consideration consists of multiple pretensioned cables attached along the length of ... -
Analytical Study of Coupling Effects for Vibrations of Cable-Harnessed Beam Structures
(American Society of Mechanical Engineers, 2019-01-22)This paper presents a distributed parameter model to study the effects of the harnessing cables on the dynamics of a host structure motivated by space structures applications. The structure is modeled using both Euler-Bernoulli ... -
Testing the Universality of Entropic Segregation at Polymer Surfaces
(2018)This study addresses entropic segregation effects at the surfaces of monodisperse and bidisperse melts. For the monodisperse melts, we focus on the segregation of chain ends to the surface, and for the bidisperse melts, ... -
Spontaneous Tilting Transition in Liquid-Crystalline Polymer Brushes
(2019)The equilibrium phase behavior of main-chain liquid-crystalline polymer brushes in good solvent is investigated using self-consistent field theory. The calculation assumes semi-dilute brushes, where the grafting density ... -
Comparing the Safety and Mobility Benefits of Alternative Winter Road Maintenance Standards
(University of Waterloo, 2019-10-24)In countries like Canada, driving conditions can be significantly deteriorated by adverse winter weather conditions, such as ice and snow storms. To reduce the negative effects caused by inclement winter weather conditions, ... -
A Study on Optimizing Infrared Heating Technology for Asphalt Pavement Maintenance and Rehabilitation
(University of Waterloo, 2019-10-24)In Canada especially, cracking and potholes on asphalt concrete pavements is a continuous problem requiring constant repairs. With the increased expansion and use of asphalt pavement infrastructure, combined with more ... -
Low-Complexity Multi-User MIMO Algorithms for mmWave WLANs
(University of Waterloo, 2019-10-24)Very high throughput and high-efficiency wireless local area networks (WLANs) have become essential for today's significant global Internet traffic and the expected significant global increase of public WiFi hotspots. Total ... -
Prosthetic Landscapes: Reclaiming the Iraqi marshes
(University of Waterloo, 2019-10-22)Hidden within the sands of the middle eastern desert, there lies a vast aging Petropolis, occupying territories in southern Iraq through the injection of infrastructure such as mechanical drills and mobile machinery. The ... -
Urban Room - Dynamic reinterpretation of Toronto’s urban voids
(University of Waterloo, 2019-10-21)Over the past few decades, Toronto’s downtown core has experienced extreme and rapid intensification, seen through an exponential increase in both employees and residents. This growth has severely outpaced that of public ... -
GREY TO GREEN 13 GATES TO THE GREENBELT
(University of Waterloo, 2019-10-21)The Greenbelt was created by the Government of Ontario in 2005 to protect working farms, wetlands, natural habitats, woods and river valleys that surround the Greater Toronto Area (GTA). Its vast 8000 square kilometers ... -
Evaluating Polymeric Materials for Sensing of Gaseous Analytes
(University of Waterloo, 2019-10-18)Polymers have been widely used in gas sensing applications especially for detecting Volatile Organic Compounds (VOCs). Some of these applications consist of disease diagnosis and breathalyzers as well as evaluation of ... -
Data, Debt & Daemons: Systemic Asymmetries on Spaceship Earth
(University of Waterloo, 2019-10-17)Day by day, the rate at which we create new data increases exponentially. Our capacity to learn cannot keep up. We are tiny members of a vast universal network, incapable of discerning cause and effect. Instead, we develop ... -
Prediction of the static modulus of elasticity in concrete cylinders using resonant tests
(University of Waterloo, 2019-10-15)Concrete is widely used in construction nowadays, and it is crucial that its behaviour conforms to the original design. In every construction site, standard concrete cylinders are cast for quality control. Concrete cylinders ... -
Re-Imagining Concrete: A Material First Design Approach
(University of Waterloo, 2019-10-15)This thesis asks the question: “What if we began the creative process of design with material?” In an age where digital images dominate the design process, architecture’s main medium of expression remains through matter. ... -
A probabilistic approach to vibration-based modal identification using mobile sensors
(University of Waterloo, 2019-10-08)Vibration-based modal identification is the process of analyzing vibration measurements in order to identify the modal properties of the structure, namely the modal frequencies, damping ratios, and mode shapes. The quality ... -
