A framework for safe system design in space launch vehicles
… for the test firing of NASA's Space Launch System core stage is performed using a systems-based alternative to the traditional reliability-based method. The method used, Systems-Theoretic Process Analysis (STPA), is shown to be a versatile and powerful tool in this application and by …

Automated interpretation of digital images of hydrographic charts.
… as input to a semi-automated feature extraction system, (SAFE). This system is able to perform a great deal of the building of chart features from the image segments simply on the basis of proximity of the segments. The system solicits user interaction when ambiguities arise. IThe creation of an …

Framework Development for Remote Clinical Trials: Assembly Process Design
… The goal is to increase enrollment and create a safe system in which to conduct medical research while requiring as little knowledge of technology from the participant as possible, in order to include the most potential participants and eventually expand into rural regions. This thesis focuses on …

The exploration of a multi-dimensional safe behaviour model for construction workers in Hong Kong : a structural equation modelling approach
Safety and Health in the workplace has long been the priority work of the Hong Kong administration but the accidentstatistics in Hong Kong tell another story. No matter how sophisticated a safe system is designed, its ultimate success depends very much on the person who carries out the job. Safe …

Factors Affecting Severity Level in Speed-Related Crashes and in Identification of Crashes Involving Exceeding Maximum Safe Travel Speed
… limit violations and those exceeding the maximum safe travel speed as determined by law enforcement. Additionally, it examines significant factors related to classifying a crash as exceeding the maximum safe travel speed. Using crash data from the Traffic Records Electronic Data System (TREDS) for …

Safety-driven system engineering process
As the demand for high-performing complex systems has increased, the ability of engineers to meet that demand has not kept pace. The creators of the traditional system engineering processes did not anticipate modern complex systems, and the application of traditional processes to complex systems …

Pedestrian safety at urban mid-block crossings
… crashes continues to remain a challenge for road safety practitioners. Pedestrian crashes are not random events. They indicate not only an underlying environmental effect but also behavioural issues related to risk-taking. For this reason, this research aimed to obtain a comprehensive insight into …
