Facilitating Brownfield Redevelopment Projects: Evaluation, Negotiation, and Policy
(University of Waterloo, 2011-05-19)A risky project evaluation technique called the fuzzy real options analysis is developed to evaluate brownfield redevelopment projects. Other decision making techniques, such as multiple criteria analysis and conflict ... -
Factors of Influence on the Performance of a Short-Latency Non-Invasive Brain Switch: Evidence in Healthy Individuals and Implication for Motor Function Rehabilitation
(Frontiers Media, 2016-01-21)Brain computer interfacing (BCI) has recently been applied as a rehabilitation approach for patients with motor disorders, such as stroke. In these closed-loop applications, a brain switch detects the motor intention from ... -
Fast Nonlinear Model Predictive Control of Quadrotors: Design and Experiments
(University of Waterloo, 2020-01-21)Quadrotor (or quadcopter) is a type of Unmanned Aerial Vehicles (UAVs). Due to the quadrotors simple and inexpensive design, they have become popular platforms. This thesis proposes a computationally fast scheme for ... -
Fast Recognition of BCI-Inefficient Users Using Physiological Features from EEG Signals: A Screening Study of Stroke Patients
(Frontiers, 2018-02-21)Motor imagery (MI) based brain-computer interface (BCI) has been developed as an alternative therapy for stroke rehabilitation. However, experimental evidence demonstrates that a significant portion (10% to 50%) of subjects ... -
Fast Stress Detection via ECG
(University of Waterloo, 2019-05-23)Nowadays stress has become a regular part of life. Stress is difficult to measure because there has been no definition of stress that everyone accepts. Furthermore, if we do not get a handle on our stress and it becomes ... -
Fault Detection and Identification in Computer Networks: A soft Computing Approach
(University of Waterloo, 2010-01-07)Governmental and private institutions rely heavily on reliable computer networks for their everyday business transactions. The downtime of their infrastructure networks may result in millions of dollars in cost. Fault ... -
Feasibility Analysis of a Powered Lower-Limb Orthotic for the Mobility Impaired User
(University of Waterloo, 2005)Powered orthotic devices can be used to restore mobility to the impaired user, and may thereby assist them in daily living tasks. An investigation is performed herein to examine the feasibility of a powered lower-limb ... -
A Feasibility Study of Micromachined Ultrasonic Transducers Functionalized for Ethanol Dectection
(University of Waterloo, 2017-08-01)The chemical sensing system plays an important role in medical and environmental monitoring. Gases exhaled by humans include nitrogen, oxygen, water vapor, carbon dioxide and volatile organic compounds (VOCs). The VOCs are ... -
Feature Analysis and Classification of Inflammatory Bowel Disease and Hidradenitis Suppurativa Using Data Mining
(University of Waterloo, 2023-03-14)Inflammatory Bowel Disease (IBD) refers to a group of conditions that primarily affect the gut and cause inflammation. In contrast, Hidradenitis Suppurativa (HS) is a chronic immune-mediated condition characterized by boils ... -
