REAL-TIME THREAT ASSESSMENT WITH IMPERFECT SENSOR DATA
… false negatives and false positives to detect a threat. The first formulation assumes that the sensor operator has intelligence on the threat likelihood at each location, while the second formulation assumes the adversary actively chooses which location to attack to evade sensor detection. In …

Near real-time threat assessment using intrusion detection system's data
… The thesis addresses the near real-time threat assessment by researching into current state of the art solutions. Based on the literature review, current Intrusion Detection technologies lean towards event correlation systems using different types of detections techniques. Instead of …

Threat Assessment for Multistage Cyber Attacks in Smart Grid Communication Networks
… grids is making smart grids vulnerable to cyber threats, as well as raising numerous concerns about the adequacy of current security approaches. As a single act of penetration is often not sufficient for an attacker to achieve his/her goal, multistage cyber attacks may occur. Due to the …

Threat assessment for safe navigation in environments with uncertainty in predictability
This thesis develops threat assessment algorithms to improve the safety of the decision making of autonomous and human-operated vehicles navigating in dynamic and uncertain environments, where the source of uncertainty is in the predictability of the nearby vehicles' future trajectories. The first …

Development of a Threat Assessment Algorithm for Intersection Collision Avoidance Systems
… mounted sensors, and communication equipment. A threat-assessment algorithm performs computations to predict the driver's intended intersection maneuver, based on these sensor inputs. If the system predicts a violation, it delivers a timely warning to the driver with the aim of compelling the …

Threat Assessment and Proactive Decision-Making for Crash Avoidance in Autonomous Vehicles
Threat assessment and reliable motion-prediction of surrounding vehicles are some of the major challenges encountered in autonomous vehicles' safe decision-making. Predicting a threat in advance can give an autonomous vehicle enough time to avoid crashes or near crash situations. Most vehicles on …

An interdisciplinary approach toward improving volcanic flank eruption threat assessment and hazard communication
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2023-12-04 without embargo terms

A unified framework for trajectory planning, threat assessment, and semi-autonomous control of passenger vehicles
… framework that performs trajectory planning, threat assessment, and semi-autonomous control of passenger vehicles in hazard avoidance scenarios. The vehicle navigation task is formulated as a constrained optimal control problem with the constraints bounding a navigable region of the …

Modeling Ecological Risks at a Landscape Scale: Threat Assessment in the Upper Tennessee River Basin
… showed that localized, moderately severe threats accounted for most of the threat composition differences among watersheds. Also, the relative importance of threats is sensitive to the spatial grain of the analysis. An evaluation of the ERI procedures showed that the protocol is sensitive …

A margin-based approach to vehicle threat assessment in a homotopy framework for semi-autonomous highway navigation
… describes the design of an unified framework for threat assessment and the shared control between a human driver and the onboard controller, based on the notion of fields of safe travel. It allows to perform corridor navigation, trajectory planning, threat assessment and driving assistance in …

A non-hardened preventative approach to deterring school crime and violence: the significance of threat assessment teams in schools across the United States
… One non-hardened example includes school threat assessment teams, which may be referred to as a formal group of people and processes that identify, assess, and manage students who might be a potential risk for violent or harmful behavior towards themselves or others (Padgett et al., 2019). …

Development of a performance-based approach for collision avoidance and mitigation
Many threat assessment algorithms are based on a collection of threshold equations that predict when a collision is to occur. The fact that there are numerous algorithms suggests a need to understand the underlying principles behind the equation design and threshold settings. This thesis presents a …

The Use of Behavioral Agreements by Senior Student Affairs Officers and Counseling Center Directors to Manage Student Mental Health Concerns and Minimize Threatening Behavior
… health concerns and minimize behavior that poses threats to campus communities. Six pairs of Senior Student Affairs Officers and Counseling Center Directors at the same institution were interviewed for this study. In addition, documents concerning mental health and threat assessment policy and …

Russian Organized Crime: Within the Parameters of a National Security Threat
… Russian organized crime (ROC) as a significant threat to the U.S. by pinning the sophistication of Russian enterprises against the traditional methods of mafia groups. This thesis uses a combination of relevant literature and previously defined threat assessment variables as groundwork to …
