We provide a new test of the feasibility of using contingent valuation to value informal care. We start with a theoretical model of informal caregiving and derive that willingness to pay depends positively on wealth ...

Seasonally dry tropical ecosystems occur in the Americas, Africa, India and Australia. They sustain large human populations, determine regional climate, are sites of biological and cultural conservation, and have significant ...

The challenges faced by coastal protected areas in both promoting highly attractive sites and preserving the natural attributes of these sites have been given a new dimension with the opportunities presented by ecotourism. ...

The design and performance of an eddy current damper for the Labshare remotely operated "Shake Table" multi-storey building vibration rig is described. The damper comprises stationary E-cores on either side of a copper ...

In a permanent magnet synchronous generator (PMSG) with modular winding, significant eddy current may be induced in the rotor magnets due to asynchronous rotating stator magneto-motive forces (MMFs), and a rectifier load ...

Differentiated Service Network (DiffServ) provides an architecture that is scalable and capable of differentiating applications’ quality of service (QoS). However, it could not control its loads under heavy traffic ...

Gradient-based edge detection is a straightforward method to identify the edge points in the original grey-level image. It is intuitive that in the human vision system the edge points always appear where the grey-level ...
