Sommario/riassunto |

The paper presents an approach for defining ICT investment proposals. The approach was developed on the authority of the Dutch Ministry of Transport, Public Works and Water Management. The Ministry was confronted with a growing amount of ICT investment proposals. Since there was no format for describing a proposal and no procedure for obtaining the data on the basis of which a proposal was described, the |

decision to select proposals for funding missed any kind of rationality. Proposals differed enormously and hence were incomparable. The evaluation of existing ICT assessment methods showed tha |

Sommario/riassunto |

Trophic cascades-the top-down regulation of ecosystems by predators-are an essential aspect of ecosystem function and well-being. Trophic cascades are often drastically disrupted by human interventions-for example, when wolves and cougars are removed, allowing deer and beaver to become destructive-yet have only recently begun to be considered in the development of conservation and management strategies. Trophic Cascades is the first comprehensive presentation of the science on this subject. It brings together some of the world's leading scientists and researchers to explain the importance of l |

"Advanced Computational Dynamicsof Particles, Materials, and Structures: A Unified Approach breaks new ground with its in-depth, detailed coverage of modern computational mechanics in particle and continuum dynamics. Kumar Tamma provides a unique blend of classical and innovative theoretical and computational approaches that cover both particle dynamics and flexible continuum structural dynamics applications. He covers both traditional methods and new developments & perspectives in both time and space discretization, encompassing classical Newtonian, Lagrangian, and Hamiltonian mechanics as well as new and alternate contemporary approaches and their equivalences to address various problems in engineering sciences and physics. The completeness and depth of coverage makes Advanced Computational Dynamics of Particles, Materials, and Structures an invaluable reference for both engineers and researchers working in the |
