Australasian gannets (Morus serrator), like many other seabird species, locate pelagic prey from the air and perform rapid plunge dives for their capture. Prey are captured underwater either in the momentum (M) phase of the dive while descending through the water column, or the wing flapping (WF) phase while moving, using the wings for propulsion. Detection of prey from the air is clearly visua...

In nature, several seabirds (e.g., gannets and boobies) dive into water at up to 24 m/s as a hunting mechanism; furthermore, gannets and boobies have a slender neck, which is potentially the weakest part of the body under compression during high-speed impact. In this work, we investigate the stability of the bird's neck during plunge-diving by understanding the interaction between the fluid for...

We present Depth Explorer, a software tool for examination of depth measures. Depth explorer was written in C++ and Objective-C. It uses a tree-based data structure to render 2-D statistical distributions and depth-based visualizations specified in XML files. We demonstrate the potential of the tool on several test cases. We present an experiments analysis of the L1 depth measure that exposes i...

To investigate the possibility of transmural recording of repolarization through the ventricular wall, KCl monophasic action potential (MAP) electrodes positioned along plunge needles were developed and tested. The MAP electrode consists of a silver wire surrounded by agarose gel containing KCl, which slowly eluted into the adjacent tissue to depolarize it. In six dogs, a plunge needle containi...

Plunge milling is a machining process recognized to be efficient for roughing deep workpieces. This due the distribution of cutting forces on tool. Important axial and reduced radial lead more rigidity, eventually productivity. It commonly used in case hard cut materials, like titanium alloys. However, plunge can exhibit problem at end plunging phase, which increase forces. Within this paper, s...

Splashing is the main atomization source for a jet impinging on liquid layer. Increased understanding of splashing rainfall characteristics can help to reduce hazard flood discharge in hydraulic engineering. In this study, spatial distribution caused by nappe flow downstream water cushion was experimentally investigated. Effects factors impingement velocity, unit discharge, and water-cushion de...
