(AIP Publishing, 2013-04-14)This work shows that when a Schottky barrier is present in a photovoltaic device, such as in a device with an ITO/ZnO contact, equivalent circuit analysis must be performed with admittance spectroscopy to accurately determine ... -
Achievable Rate Regions of Two-Way Relay Channels
(University of Waterloo, 2017-01-19)With the fast development of communication networks, cooperative communication has been more widely used in many different fields, such as satellite networks, broadcast networks, internet and so on. Therefore relay channels ... -
Achieving contrapuntal balance at a lake outlet: Restoring salmon spawning habitat with gravel augmentation design
(University of Waterloo, 2024-04-09)The degradation of gravel bed rivers in logging and climate-impacted watersheds has led to an increase in salmonid habitat conservation and restoration efforts. Gravel augmentation is one such technique that seeks to restore ... -
Achieving Drag Reduction Through Polymer-Surfactant Interaction
(University of Waterloo, 2013-08-30)Drag reduction is a well-observed phenomenon, it was first observed by the British chemist Toms in 1946, yet its mechanism is still unknown to this day. Polymer Drag reduction has found application in reducing pumping costs ... -
Achieving Fairness in 802.11-Based Multi-channel Wireless Mesh Networks
(University of Waterloo, 2006)Multi-hop wireless networks based on 802. 11 are being used more widely as an alternative technology for last-mile broadband Internet access. Their benefits include ease of deployment and lower cost. Such networks are ... -
Achieving Scalable, Exhaustive Network Data Processing by Exploiting Parallelism
(University of Waterloo, 2004)Telecommunications companies (telcos) and Internet Service Providers (ISPs) monitor the traffic passing through their networks for the purposes of network evaluation and planning for future growth. Most monitoring ... -
Achieving Soft Real-time Guarantees for Interactive Applications in Wireless Mesh Networks
(University of Waterloo, 2008-01-25)The use of 802.11-based multi-hop wireless mesh networks for Internet access is extensive and growing. The primary advantages of this approach are ease of deployment and lower cost. However, these networks are designed for ... -
ACL Strain During Single-Leg Jump Landing: An Experimental and Computational Investigation
(University of Waterloo, 2019-01-11)The anterior cruciate ligament (ACL) is a commonly-injured ligament in the human knee joint. ACL injury repair is a costly procedure; however, left unrepaired, ACL injuries can lead to complications later in life. In ... -
Acoustic Monitoring for Leaks in Water Distribution Networks
(University of Waterloo, 2020-04-21)Water distribution networks (WDNs) are complex systems that are subjected to stresses due to a number of hydraulic and environmental loads. Small leaks can run continuously for extended periods, sometimes indefinitely, ... -
Acquiring Multimodal Disaggregate Travel Behavior Data Using Smart Phones
(University of Waterloo, 2013-01-25)Despite the significant advances that have been made in traffic sensor technologies, there are only a few systems that provide measurements at the trip level and fewer yet that can do so for all travel modes. On the other ... -
Across the River: A Library Reflected
(University of Waterloo, 2009-06-19)The thickening line crafted as a ‘temporary’ border thirteen years ago during the Dayton Peace Agreement –dividing Bosnia into Republika Srpska and the Federation of Bosniaks and Croats- is gaining an unsettling permanence ... -
Acrylonitrile copolymer/graphene skinned cathode for long cycle life rechargeable hybrid aqueous batteries at high-temperature
(Elsevier, 2018-04-01)For aqueous rechargeable lithium battery (ARLB), excellent cycling stability at elevated temperature is highly desirable in its application of electric vehicles (EVs). However, most state-of-art ARLBs show poor durability ... -
Activating Play-Based Escape, Awakening Creativity
(University of Waterloo, 2011-05-20)Everyone participates in escape. The drive to escape is something we are born with. It is a force that has ties to our curiosity, as well as our profound psychological restlessness, and can even be seen in our displeasure ... -
