An Improved Model for the Dynamic Routing Effect Algorithm for Mobility Protocol
(University of Waterloo, 2005)An ad-hoc network is a packet radio network in which individual mobile nodes perform routing functions. Typically, an ad-hoc networking concept allows users wanting to communicate with each other while forming a temporary ... -
Improved Model Poisoning Attacks and Defenses in Federated Learning with Clustering
(University of Waterloo, 2022-05-12)Federated Learning (FL) allows multiple participants to collaboratively train a deep learning model without sharing their private training data. However, due to its distributive nature, FL is vulnerable to various poisoning ... -
Improved Models for the Potential Energy Functions of the Ground Singlet and Lowest-Lying Triplet States of the Cesium Dimer
(University of Waterloo, 2012-08-23)The Morse/Long Range (MLR) potential has become one of the most reliable and highly used potential energy functions for diatomic molecules. It includes the theoretical long range behaviour that diatomic molecules are ... -
Improved Multi-resolution Analysis of the Motion Patterns in Video for Human Action Classification
(University of Waterloo, 2011-10-03)The automatic recognition of human actions in video is of great interest in many applications such as automated surveillance, content-based video summarization, video search, and indexing. The problem is challenging due ... -
Improved Numerical Methods for Distributed Hydrological Models
(University of Waterloo, 2010-01-21)Distributed hydrological models have been used for decades to calculate and predict the movement of water and energy within watersheds. These models have evolved from relatively simple empirical applications into complex ... -
Improved Overlay Alignment of Thin-film Transistors and their Electrical Behaviour for Flexible Display Technology
(University of Waterloo, 2010-12-20)The integration of hydrogenated amorphous silicon (a-Si:H) thin-film transistors (TFTs) with plastic substrates enables emerging technologies such as flexible organic light emitting diode (OLED) displays. Current a-Si ... -
Improved Particle Filter Based Localization and Mapping Techniques
(University of Waterloo, 2008-04-28)One of the most fundamental problems in mobile robotics is localization. The solution to most problems requires that the robot first determine its location in the environment. Even if the absolute position is not necessary, ... -
Improved Scalability and Accuracy of Bayesian Network Structure Learning in the Score-and-Search Paradigm
(University of Waterloo, 2023-05-16)A Bayesian network is a probabilistic graphical model that consists of a directed acyclic graph (DAG), where each node is a random variable and attached to each node is a conditional probability distribution (CPD). A ... -
Improved Schedule Analysis Considering Rework Impact and Optimum Delay Mitigation
(University of Waterloo, 2009-12-11)Rework has been a primary cause of cost and schedule overruns in the construction of heavy industrial projects such as those related to oil and gas. It has been reported that the direct cost of rework is about 5% of total ... -
Improved Slow Feature Analysis for Process Monitoring
(University of Waterloo, 2022-08-22)Unsupervised multivariate statistical analysis models are valuable tools for process monitoring and fault diagnosis. Among them, slow feature analysis (SFA) is widely studied and used due to its explicit statistical ... -
An Improved Static Seismic Design Method for Podium Structures with Vertical Irregularity of Mass and Stiffness
(University of Waterloo, 2021-01-12)Owing to potentially reduced costs and faster project timelines, North American designers are increasingly opting for novel structural systems that are not well-addressed by the current model codes. Specifically, mid-rise ... -
Improved Streamflow Simulation through Ensemble and Stochastic Conceptual Data-driven Approaches
(University of Waterloo, 2022-08-18)To better understand the complexities of water movement on earth, hydrologists have developed process-based hydrological models (HMs) and data-driven models (DDMs), both of which have been applied to a host of water resources ... -
Improvement of fatigue and corrosion-fatigue resistance of AZ31B cast alloy by cold spray coating and top coating
(University of Waterloo, 2017-05-16)Recent advancements in manufacturing of light-weight structures have caused high interest in industries toward magnesium alloys because of its excellent properties such as specific strength, low density, and fatigue strength. ... -
