A mathematical model, based on current knowledge of gas exchange and physiology of marine mammals, was used to predict blood and tissue tension N2 (P(N2)) using field data from three beaked whale species: northern bottlenose whales, Cuvier's beaked whales, and Blainville's beaked whales. The objective was to determine if physiology (body mass, diving lung volume, dive response) or dive behaviou...

Sound-and-orientation recording tags (DTAGs) were used to study 10 beaked whales of two poorly known species, Ziphius cavirostris (Zc) and Mesoplodon densirostris (Md). Acoustic behaviour in the deep foraging dives performed by both species (Zc: 28 dives by seven individuals; Md: 16 dives by three individuals) shows that they hunt by echolocation in deep water between 222 and 1885 m, attempting...

At some point in a dive, breath-hold divers must decide to return to the surface to breathe. The issue of when to end a dive has been discussed intensively in terms of foraging ecology and behavioral physiology, using dive duration as a temporal parameter. Inevitably, however, a time lag exists between the decision of animals to start returning to the surface and the end of the dive, especially...

Every generation of wireless technologies needs to bring a set new system capabilities enable future applications and services, the sixth mobile (6G) is no exception. This paper provides an overview technology transformation from communication-centric forth (4G) fifth (5G) compute-centric 6G with cloud-native framework as foundation next technologies. We explain what plans achieve, fundamental ...

Cormorants hunt both benthic (sedentary) and pelagic (motile) prey but it is not known if the energy costs of foraging on these prey differ. We used respirometry to measure the costs of diving in double-crested cormorants (Phalacrocorax auritus) foraging either for sedentary (fish pieces) or motile (juvenile salmon) prey in a deep dive tank. Short dives for sedentary prey were more expensive th...

cairostris (Cuvier’s beaked whale) and Mesoplodon densirostris (Blainville’s beaked whale). The authors find that both of these species undertake long, deep dives to capture deepwater prey. Diving is highly regular with most deep foraging dives being followed by an extended period of shallow dives and slow travel and resting near the surface. All foraging dives of both species are considerably ...

Purpose The paper aims to convert into useable guidelines, the knowledge related human factors and tasks' organisation, which are embedded in one of most exciting maintenance actions that carried out, pitstop Formula 1 races. Design/methodology/approach opted for a fault tree analysis (FTA) de-construct all sub-tasks their possible deviations from desirable situations evaluate relevant informat...

Many researchers try to make a comparison between various Internet-of-Things (IoT) platforms based on specific requirements. However, none of the reviewed studies proposed thorough analysis variety comparative methods. Since there is lack frameworks for IoT platforms, individuals or companies have difficulties when selecting suitable platform matching their associated business In order support ...
