  • The use of models to provide additional details on contaminant fate and transport has rapidly increased in the past 3 decades. The increasing global recognition of the potential risks associated with surface water or ground water contamination and speciÞc environmental regulations implemented after 1980 have demanded a more accurate understanding of these risks as they relate to human health and the environment.

  • Characterizing the nature of heavy metal release reactions, sorption mechanisms, and movement in the soil is the main topic of this book. Because soils are heterogeneous, heavy metals in soils can be involved in a series of complex chemical and biological interactions including oxidation-reduction, precipitation and dissolution, volatilization, and surface and solution phase complexation. The heterogeneous nature of the different soil constituents adds to the complexity of interactions of heavy metal species with the soil environment....

  • The ability to create intelligent machines has intrigued humans since ancient times, and today with the advent of the computer and 50 years of research into AI programming techniques, the dream of smart machines is becoming a reality. Researchers are creating systems, which can mimic human beings. Accurate mathematical models neither always exist nor can they be derived for all complex environments because the domain may not be thoroughly understood. The solution consists of constructing rules that apply when input values lie within certain designer-defined categories....

  • Visual Basic 2005, together with the .NET Framework, provides a wonderfully powerful development environment. With these tools, developers can build amazingly powerful applications relatively quickly and easily. With this power, however, comes great complexity. Many books are available that discuss the Visual Basic language, and if you need to build a relatively simple application, those are generally sufficient. No books, however, address the complex issues that surround the development of more complicated Visual Basic applications.

  • Some studies are content with establishing simple correlations, while others involve sophisticated econometric analysis, attempting to ascertain the existence and direction of causality. Yet other studies involve complex systems with feedback loops or large simulation models with scenario analysis. Inevitably, they reach different conclusions even when they analyze the same body of data because of differences in perspectives, levels of aggregation and methods of analysis.

  • The idea of using markets and pricing computer re- sources is quite old. Pricing policies received consid- erable attention at the dawn of modern multi-user time sharing systems. Papers in the late 1960’s were dedi- cated to automated pricing policies for computer time [18, 19, 20]. As research, this work was short-lived. The complexity of these schemes relative to their benefit, combined with the environment of time-shared systems (mostly cooperative, mostly controlled by a single en- tity) quickly made pricing for shared resource allocation a low priority.

  • Media skills play an increasingly important role in the gathering and sharing of ideas and information. At the core of media mastery are the same fundamental capacities as are required “offline” in traditional print forms: an ability to produce clear communications and an ability to access, understand, and evaluate complex materials and messages. Media mastery also calls upon some skills unique to the online environment, ranging from being able to conduct digital-based research to exchanging and debating ideas in online discussions to interacting with new text forms.

  • To address this need, PricewaterhouseCoopers has developed the Hub and Spokes Resource Model ™. The Hub and Spokes Resource Model assumes that certain core internal audit resources and capabilities will remain resident within the company. This “hub” provides internal audit with the leadership, continuity and experience that are unique to your organisation. The “spokes” in the model represent elements of a possible cosourcing relationship.

  • Malnutrition results from a complex set of factors and not one simple cause. The UNICEF conceptual model of causes of malnutrition (page 16) provides a useful framework for the discussion of the causes of malnutrition in Somalia. The volatile political situation and civil unrest have led to a chronic and continuing humanitarian crisis that is at the root of the high prevalence of malnutrition in Somalia. Somalia is also prone to drought and floods.

  • Using CAE programs, a mechanical design team can quickly and cheaply iterate the design process to develop a product that better meets cost, performance, and other constraints. No physical prototype need be created until the design nears completion, allowing hundreds or thousands of designs to be evaluated, instead of a relative few. In addition, CAE analysis programs can model complicated physical phenomena which cannot be solved by hand, such as viscoelasticity, complex contact between mating parts, or non-Newtonian flows....

  • Building on MATLAB (the language of technical computing), Simulink provides a platform for engineers to plan, model, design, simulate, test and implement complex electromechanical, dynamic control, signal processing and communication systems. Simulink-Matlab combination is very useful for developing algorithms, GUI assisted creation of block diagrams and realisation of interactive simulation based designs. The eleven chapters of the book demonstrate the power and capabilities of Simulink to solve engineering problems with varied degree of complexity in the virtual environment....

  • In recent years, flow control and network management in high speed networks have drawn much attention by researchers in the telecommunications field. In large-scale network environments with high complexity, decentralized control and decision making are required. Many research papers concerned with multidisciplinary approaches to modeling, controlling and managing networks from a computational intelligence point of view appear in the key telecommunication journals every year.

  • The basic physics of sound propagation are simple, but the interaction of sound pressure waves with complex shapes and multi-layer constructions with openings, as you find in buildings, is more challenging. Controlling noise, both from the internal and external environment and from the internal mechanical and electrical services in buildings, is essential to create environments that promote aural communication and comfortable working conditions.

  • Given the spatial relationships extracted as described above, our goal is to integrate this information into an optimization framework with a properly defined cost function quantifying the quality of the furniture arrangement. Given an arbitrary room layout populated by furniture objects, the synthesized arrangement should be useful for virtual environment modeling in games and movies, interior design software, and other applications. The search space of our problem is highly complex as objects are interdependent in the optimization process.

  • The main focus of this book is the presentation of the “inertial” view of population growth. This view provides a rather simple model for complex population dynamics, and is achieved at the level of the single species, without invoking species interactions. An important part of our account is the maternal effect. Investment of mothers in the quality of their daughters makes the rate of reproduction of the current generation depend not only on the current environment but also on the environment experienced by the preceding generation....
