    • Digital Signature Scheme Variations 

      Dunbar, Fiona (University of Waterloo, 2002)
      A digital signature scheme is the process of signing an electronic message that can be transmitted over a computer network. Digital signatures provide message authentication that can be proved to a third party. With ...
    • Digital Signature Schemes Based on Hash Functions 

      Lafrance, Philip (University of Waterloo, 2017-04-19)
      Cryptographers and security experts around the world have been awakened to the reality that one day (potentially soon) large-scale quantum computers may be available. Most of the public-key cryptosystems employed today on ...
    • Digital Signcryption 

      Smith, Clayton D. (University of Waterloo, 2005)
      Signcryption is a new cryptographic primitive which simultaneously provides both confidentiality and authenticity. Previously, these two goals had been considered separately, with encryption schemes providing confidentiality ...
    • Digital Terrain Models Generation from Airborne LiDAR Point Clouds Using A Multi-scale Terrain Filtering Method 

      Chen, Hufeng (University of Waterloo, 2012-05-23)
      A Digital Terrain Model (DTM) is an important topographic product, required in many applications. Data needed to create a DTM was traditionally obtained via land surveying, however this method can be costly and time consuming ...
    • Digital Timing Control in SRAMs for Yield Enhancement and Graceful Aging Degradation 

      Neale, Adam (University of Waterloo, 2010-08-16)
      Embedded SRAMs can occupy the majority of the chip area in SOCs. The increase in process variation and aging degradation due to technology scaling can severely compromise the integrity of SRAM memory cells, hence resulting ...
    • Digital Tuft Flow Visualisation of Wind Turbine Blade Stall 

      Swytink-Binnema, Nigel (University of Waterloo, 2014-05-20)
      Wind turbines installed in the open atmosphere experience much more complex and highly-varying flow than their counterparts in wind tunnels or numerical simulations. In particular, aerodynamic stall—which occurs often on ...
    • Digital Twin Feed Drive Identification for Virtual Process Planning 

      Tseng, Ginette Wei Get (University of Waterloo, 2018-10-04)
      Computer numerical controlled (CNC) machines have become an integral part of the manufacturing industry, allowing companies to increase the accuracy and productivity of their manufacturing lines. The next step to improving ...
    • Digital Twin Framework and Auto-Linking for Management of Legacy Assets 

      Edwards, Chloe (University of Waterloo, 2021-04-30)
      The integration of Digital Twins (DTs) for facility and asset management is becoming increasingly common with the advancement of sensor and modelling technology. A digital twin is defined as a responsive and virtual ...
    • Digitally-Assisted RF-Analog Self Interference Cancellation for Wideband Full-Duplex Radios 

      King, Kimberley Brynn (University of Waterloo, 2016-10-25)
      The ever-increasing demand for more data from users is pushing the development of alternative wireless technologies to improve upon network capacity. Full-Duplex radios provide an exciting opportunity to theoretically ...
    • Digraph Algebras over Discrete Pre-ordered Groups 

      Chan, Kai-Cheong (University of Waterloo, 2013-01-25)
      This thesis consists of studies in the separate fields of operator algebras and non-associative algebras. Two natural operator algebra structures, A ⊗_max B and A ⊗_min B, exist on the tensor product of two given unital ...
    • Dilation methods in semigroup dynamics and noncommutative convexity 

      Humeniuk, Adam (University of Waterloo, 2022-08-25)
      Since seminal work of Stinespring, Arveson, and others, dilation theory has been an indispensable tool for understanding operator algebras. Dilations are fundamental to the representation theory of operator systems and ...
    • The Dilemma of Proxy-Agency in Exercise: a Social-Cognitive Examination of the Balance between Reliance and Self-Regulatory Ability 

      Shields, Christopher Andrew (University of Waterloo, 2005)
      Social Cognitive Theory (SCT: Bandura, 1997) has been used successfully in understanding exercise adherence. To date, the majority of the exercise research has focused on situations of personal agency (i. e. , self ...
