Animals are attracted to human food subsidies worldwide. The behavioral response of individuals to these resources is rarely described in detail, beyond chances of encounters. Seabirds for instance scavenge in large numbers at fishing boats, triggering crucial conservation issues, but how the response to boats varies across encounters is poorly known. Here we examine the behavioral response of ...

Finding new ways for traveling at a high commercial speed, comfortable, safe, cheap and preserving as much as possible the environment by using less fuel is the new challenge for the public transport operators that run their business in the 21st century. One of the alternatives for the passengers that are using public transportation vehicles is to travel using water buses or ferries. The paper ...

The Command and Control theory of John Boyd, a 20 century military strategist, allow us to introduce computing techniques that are able to speed up the OODA loop (Observe–Orient–Decide–Act), especially on observing and orienteering steps. This paper introduces a low cost framework capable of monitoring people, vehicles, boats, or any other elements of interest, almost in real time. The goal of ...

OBJECTIVE In 1999, the Metropolitan Ambulance Service (MAS), Melbourne, Australia began implementing The Emergency Operations Plan (1998). One of the initiatives of the plan was the addition of crews with one advanced paramedic skills (APS) officer and one non-APS officer (mixed crews). All previous APS crews contained two APS officers working together. There was concern that mixed crews would ...

The integrated aircraft routing and crew scheduling problem consists in determining a minimum-cost set of aircraft routes and crew pairings such that each 1ight leg is covered by one aircraft and one crew, and side constraints are satis2ed. While some side constraints involve only crews or aircraft, linking constraints impose minimum connection times for crews that depend on aircraft connection...

The serial protocols like PCI Express and USB have evolved over the years to provide very high operating speeds and throughput. This evolution has resulted in their physical layer protocol becoming very complex. One of the important task in the Physical layer of PCIe 3.0 is the monitoring and sampling different Ordered sets and Data Packets that come from different layers.

Hydrodynamics of porpoising instability in vertical-plane motions of high-speed planing vessels have been investigated for years. However, not much work has been published on dynamic control of vertical-plane motions of planing boats by controllable appendages. In this paper, effects of controllable transom flaps on heave/pitch motion characteristics of high-speed planing vessels are investigat...

Logging on islands differs considerably from logging carried out on the mainland. The transportation of machines to the islands and between islands calls for special equipment. Furthermore, the long distance transport must be done simultaneously with logging, because the buffer raft between ground forwarding and vessel transport is very small and used also for the transport of logging machines ...
