Automated berthing (parking) of autonomous ships

open access: yes, 2018
Shipping operations can increase their efficiency by automating standard operations. This thesis explores the concept of automated navigation in a static harbor environment and automating the berthing procedure for a commercial ship. The ship is actuated with two stern azimuth thrusters and a bow tunnel thruster, giving it full maneuverability.

The gift remembered: The Human Anatomy and Physiology Society (HAPS) Anatomical Donor Stewardship's ethical and practical handbook for anatomy donor tributes

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Providing students with a way to honor human body donors during or after an anatomy course has been shown to help provide a sense of closure and comfort to students and, when present, donor families. Gestures of gratitude for donors can also emphasize humanistic values of respect, empathy, and professionalism.
