Salmon aquaculture generates good output (i.e., salmon) and bad output (e.g., pollution). A joint production function approach is applied to model both outputs simultaneously. Two environmental production technologies are specified, namely, regulated and unregulated technologies. Two production functions with different mapping rules are applied. Pollution abatement costs are estimated based on ...

See related article Although a relatively rare disease in the general community, idiopathic pulmonary fibrosis (IPF) is most common cause of chronic interstitial lung overall and its incidence increases markedly over age 60 years. With establishment IPF registries many countries, we are finally getting handle on epidemiology. It becoming clear that this not truly ‘idiopathic’ interactions betwe...

Air pollution has received considerable attention by local and global communities (Wald et al, 1999). Many major cities have established air quality monitoring stations but these stations tend to be scarcely distributed and do not provide sufficient tools for mapping atmospheric pollution since air quality is highly variable (Wald et al, 1999). Satellite remote sensing is a valuable tool for as...

Mobile computing has the potential to allow both experts and the public to collect and understand environmental data such as pollutants in urban areas. We describe an experimental system—eGS—that allows users to explore a city area while collaboratively visualising a common atmospheric pollutant— carbon monoxide—in real-time. Users carry a networked tablet PC. Using GPS and an attached sensor, ...

The purpose of this paper is to apply recent developments in the areas of the ‘Quantified Self’ and the ‘Internet of Things’ in order to explore the use of low-cost sensors for the collection of a variety of spatially-referenced biometric and environmental data from participants. This is achieved using a specially designed application on the Android mobile platform, which has been developed for...

Given non-degenerate intervals X of R and an increasing ordered mapping Φ : X × · · · ×X → R , games in strategic form between N players with the X as action sets with the following three properties are studied: the set of Nash equilibria E is convex, Φ is constant on E and in each Nash equilibrium at least one payoff function is not partially differentiable w.r.t. its own action. The results a...

In this paper, we discuss the main informatics challenges that arise when a high throughput sensor network is constructed with view to addressing real environmental challenges, such as real-time urban air pollution monitoring and mapping. We present a distributed infrastructure based on grid technology and data integration and mining tools, and describe our experience in developing such compone...

The work deals with the application of Support Vector Machines (SVM) for environmental and pollution spatial data analysis and modeling. The main attention is paid to classification of spatially distributed data with SVM and comparison with probabilistic mapping using nonparametric geostatistical model (indicator kriging). SVMs with RBF kernels were used. It is shown that optimal bandwidth of k...

To address the air pollution diffusing problem, a visualization algorithm based on fluid diffusion physical model and volume rendering is proposed to simulate the diffusion process epically for the urgent pollution accidents. The diffusion model is based on the simplified heat diffusion equation and the basic vortex constraint. The texture mapping based volume rendering method is adapted to han...
