Discovery of trend dependencies over time-series
(2023-11-01)We improve constraint-based data quality using trend dependency (TD) discovery, extending existing order dependencies (ODs) to allow variations and exceptions. Unlike ODs, TDs capture approximate functional mappings between ... -
Sidewalk extraction using deep learning and cost-based route optimization with mini-max objective function
(2023-12-01)With the growing diversification of modern urban transportation options, such as small-scale autonomous delivery vehicles, autonomous patrol robots, e-bikes, and e-scooters, sidewalks have gained newfound importance as ... -
Preferential proximal policy optimization in reinforcement learning
(2023-12-01)The Proximal Policy Optimization (PPO), a policy gradient method, excels in reinforcement learning with its ”surrogate” objective function and stochastic gradient ascent. However, PPO does not fully consider the significance ... -
Breaking the silence: an intersectional approach to sexual violence and harm narratives of women living in Lebanon
(2023-10-01)Lebanon has experienced war and conflict for the last four decades, yet there is an absence of literature on Lebanese women’s lived experience of the Lebanese Civil War (LCW) (April 1975 – October 1989), and the ongoing ... -
Formerly incarcerated women’s online accounts of pathways to criminality and incarceration: a contribution to feminist pathways theory
(2023-11-01)Some feminist scholars argue that pathways research is not truly representative of girls’ and women’s pathways to crime. This paper uses the gendered pathways theory that recognizes and highlights some of the unique factors ... -
Energy aware scheduling using reinforcement learning for 802.15.4e Time-Slotted Channel Hopping
(2023-11-01)Time Slotted Channel Hopping (TSCH) is a medium access control mode defined in IEEE 802.15.4e standard. This protocol is a crucial component of fourth-generation IoT applications, enabling efficient communication through ... -
Improving classification system to detect cyclic alternation pattern using sleep EEG
(2023-08-01)Cyclic alternative patterns (CAP) became an important tool to diagnose sleep disorders. This study aims to have a better understanding of CAP, as the clinical applications remain limited as CAP analysis is a time-consuming ... -
Characterization of flow control using programmable multi-directional plasma actuators
(2023-09-01)This research explores the use of a novel plasma actuator geometry and electrical configuration to generate directionally programmable flow fields near the surface of arrays of such plasma actuators. Plasma actuators are ... -
Understanding minor attracted persons
(2023-10-01)Minor attracted persons (MAPs) are a group of understudied individuals who acknowledge a sexual interest in children but who may never have offended against a child. They are often regarded the same as individuals who have ... -
Modelling of radioactive particle resuspension after a dirty bomb event
(2023-12-01)The primary hazard of a Dirty Bomb emanates not from the initial detonation but from the subsequent re-suspension of deposited radioactive particles. Although radiological contamination is substantial on surfaces initially, ... -
PoT: bridging IoT with phone technology
(2023-09-01)The ”Phone of Things” (PoT) introduces an innovative integration of IoT systems with the widely available telephone network infrastructure. It repurposes underused home landlines and existing communication servers, weaving ... -
Coordinated multicast beamforming for multi-cell massive MIMO systems
(2023-09-01)In this thesis, we consider the efficient coordinated multi-cell multicast beamforming design in massive massive multiple-input multiple output (MIMO) cellular networks. For the problem that aims to minimize the base station ... -
Optimizing electrocardiogram analysis for efficient heart condition diagnosis
(2023-09-01)This thesis introduces an innovative lead grouping strategy for efficient real-time Electrocardiography signal classification. This method uses a maximum of six leads instead of the traditional 12-lead approach, leading ... -
Effects of per-and polyfluoroalkyl substances (PFAS) on the freshwater gastropod (Planorbella pilsbryi) in the laboratory and in situ integrating a multi-omic approach
(2023-09-01)Per- and polyfluoroalkyl substances (PFAS) are anthropogenic chemicals that are globally used in consumer and industrial applications. Specifically, perfluorooctane sulfonate (PFOS) has been under scrutiny due to its ... -
Analysis and techniques of cyberattack types classification in smart grids
