Deploying an ITS Warning System for No-Passing Zones on Two-Lane Rural Roads
A new safety application, as part of ITS Advanced Rural Transportation System (ARTS), has been developed to be deployed on a two-lane rural road (Route 114), in Southwest Virginia. The route segment under study is subject to significant head-on accidents, as a result of two main conditions: 1- …

High power X-band RF test stand development and high power testing of the CLIC crab cavity
This thesis describes the development and operation of multiple high power X-band RF test facilities for high gradient acceleration and deflecting structures at CERN, as re-quired for the e+ e- collider research programme CLIC (Compact Linear Collider). Signif-icant improvements to the control …

Front underride protection devices: design methodology for heavy vehicle crashworthiness
North American Heavy Vehicles contribute to a third of all road fatalities in Canada. Head on collisions are one of the most severe, as the mismatch of vehicle weight and sizing intensifies when a passenger vehicle is impacted. To improve crash safety, Front Underride Protection Devices (FUPDs) are …

Development and application of a probabilistic risk assessment model for evaluating advanced train control technologies
Quantitative research on risk and train control has traditionally relied exclusively on historical accident data. In this thesis, a model is developed that enables a probabilistic rather than statistical assessment of safety improvements achieved with advanced train control technologies. This …

Physical minimal models of amoeboid cell motility
Cell locomotion plays an important role in many biological processes such as the immune system, embryonic development, or cancer metastasis. In these examples, cells interact with their environments or coordinate their movements with other cells, creating collective behavior. In this thesis, we …

Measurement of non-flow correlations and elliptic flow fluctuations in Au+Au collisions at RHIC
… of collective flow and two-particle correlations have proven to be effective tools for understanding the properties of the system produced in ultrarelativistic nucleus-nucleus collisions at the Relativistic Heavy Ion Collider (RHIC). Accurate modeling of the initial conditions of a heavy ion …

Evaluating Factors Contributing to Crash Severity Among Older Drivers: Statistical Modeling and Machine Learning Approaches
… severe injuries and fatalities. This dissertation embarks on a comprehensive examination of the factors affecting road crash severity, with a special focus on older drivers and the unique challenges introduced by the COVID-19 pandemic. Utilizing a dataset from Virginia, USA, the research …

Characteristics and contributory causes related to large truck crashes (phase-II) - all crashes
… safety of the overall surface transportation system, each of the critical areas needs to be addressed separately with more focused attention. Statistics clearly show that large-truck crashes contribute significantly to an increased percentage of high-severity crashes. It is therefore …

Uncovering gravitational wave signatures of modified theories of gravity and exotic matter
The observation of the first gravitational-wave (GW) event almost a decade ago opened a new promising window to our scientific endeavours in understanding the deepest mysteries of our Universe and its history. Using the foundations of general relativity (GR), we are now in the position of being …
