This paper presents an interactive multi-objective evolutionary optimization based approach to solve the inverse problem of estimating heterogeneous aquifer parameters (in this case hydraulic conductivity) for a groundwater flow model. A hypothetical aquifer, for which the ‘true’ parameter values are known, is used as a test case to demonstrate the usefulness of this method. It is shown that us...

High-nitrogen loadings of rivers and aquifers systems are a major concern because of potential effects on human health and water quality impacts such as eutrophication of lakes and coastal zones. This nitrogen enrichment is commonly attributed to anthropogenic sources such as sewage and agricultural and industrial wastes. The aims of this study were to delineate spatial distribution of groundwa...

Postmodernism is a very ambiguous term. It attracted many researchers from different fields of knowledge in the late 1960s. This article explains intertextuality as a critical means to derive its concepts and components in order to understand the hidden layers of meaning in postmodern pluralist ideology. Variable thoughts of postmodern architecture have been divided into two categories—Hi...

The following analytical approaches: queuing network models, stochastic automata networks, stochastic timed Petri nets, stochastic process algebra, Markov chains can be used in performance evaluation of multi–agent systems. In this paper, new approach which is based on PERT networks is presented. This approach is applied in performance evaluation of layered multi–agent system. Time-out mechanis...

A general initial-boundary value problem of one-dimensional transient wave propagation in a multi-layered elastic medium due to arbitrary boundary or interface excitations (either prescribed tractions or displacements) is considered. Laplace transformation technique is utilised and the Laplace transform inversion is facilitated via an unconventional method, where the expansion of complex-valued...

Such measurements also could enable effective realtime system monitoring and control, which are considered to be the key to preventing wide-sc...

We formulate a hydro-economic model of the North-Western Sahara Aquifer System (NWSAS) to assess effects intensive pumping on groundwater stock and examine subsequent consequences aquifer depletion. This large system comprises multi-layer reservoirs with vertical exchanges, all exploited under open access properties. first develop theoretical account for relevant features NWSAS by introducing, ...

Physically-based animation techniques enable more realistic and accurate animation to be created. We present a GPU-based finite element (FE) simulation and interactive visualisation system for efficiently producing realisticlooking animations of facial movement, including expressive wrinkles. It is optimised for simulating multi-layered voxel-based models using the total Lagrangian explicit dyn...

This paper describes the development of a layered structure of a multi-resolutional scalable video codec based on the Color Set Partitioning in Hierarchical Trees (CSPIHT) scheme. The new structure is designed in such a way that it supports the network Quality of Service (QoS) by allowing packet marking in a real-time layered multicast system with heterogeneous clients. Also, it provides (spati...
