1. Invasive species threaten marine biodiversity on a global scale. 2. To test whether marine reserves provide resistance to invading species, the abundance of two conspicuous invaders, a seaweed and an oyster, were measured inside marine reserves and in comparable areas outside reserves in north-western Washington State. 3. Densities of both invaders were significantly higher in marine reserve...

The conversion of solar energy into electricity makes it possible to generate a power resource at the relevant location, independent availability electrical network. application technology greatly facilitates supply objects that, due their cannot be connected Typical areas use are nature reserves, game management areas, large-scale agricultural livestock industrial pipeline routes, water resour...

This paper, presents an adapted serious game for rating social ability in children with autism spectrum disorder (ASD). The required measurements are obtained by challenges of the proposed serious game. The proposed serious game uses reinforcement learning concepts for being adaptive. It is based on fuzzy logic to evaluate the social ability level of the children with ASD. The game adapts itsel...

Independently owned nature reserves are proliferating across the developing world. Nevertheless, the conservation community knows practically nothing about them. This paper examines the economic, ecological, and social impacts of ecotourism, as evidenced at thirty-two of these reserves. Ecotourism is shown to be the primary means through which reserves survive financially. This reliance provide...

Synopsis: The paper ‘bridges the divide’ between the biological and economic literature on marine reserves. It provides a selected review of the traditional use of reserves, the early reserve literature, the potential benefits of reserves, spillovers from reserves to harvested areas and bioeconomic models of marine reserves. The bioeconomics literature is examined from the perspectives of deter...

Despite being targeted as a conservation flagship species for several decades, the tiger (Panthera tigris) grows ever more imperiled. Debate exists as to where tiger conservation should focus: on protected nature reserves or larger landscapes. We developed a landscape scale, density-based model to assess whether reasonably effective management of current reserves is adequate to ensure the survi...

The successful operation of interconnected power systems requires the balance of electricity generation and consumption. This is performed by frequency control that comprises three level control processes known as primary, secondary, and tertiary control. First, primary control stabilizes frequency within some seconds. Next, secondary control keeps the frequency close to its nominal values and ...

in this paper, a novel hybrid model based on neural network and game theory is proposed to support the analyzers in oil market. in this model, first the neural network is utilized to learn the oil prices associated with opec production level and usa imports level. then the learned neural network is applied by a game model. finally the nash equilibrium points of the game present the optimum deci...
