Evaluation of performance of irrigation systems is one from many solutions of water problems. This study compares the artificial neural network (ANN) approach with analytical solutions namely exact solution and dimensionless analysis, in order to predict of the performance and energy losses of irrigation systems. Three irrigation systems were chosen for their widely used now days in EGYPT; those systems were gated (perforated) pipes system, solid set sprinkler system and surface trickle irrigation system. A computer friendly user interfaces were developed to help agricultural and extension engineers in decision making, planning and designing irrigation system. The results showed the higher accuracy of using ANN models than analytical models in respect of field data. In addition, this study showed usefulness of using ANN technique as extension tool. Finally, this study recommended more studies well be helpful in improving ANN models and using them for agricultural and extension engineering.

This book takes a cross-disciplinary and cross-cultural look atmass appraisal expertise for property valuation in different marketconditions, and offers some cutting- edge approaches. The editors establish an international platform and present thescientific debate as well as practical feasibility considerations.Heretic and orthodox valuation methods are assessed based onspecific criteria, partly technical and partly institutional.Methodological evaluation is approached using two types ofcriteria: operational concerns about how to determine propertyvalue differentials between spatial and functional units of realestate in a valid and reliable way (technical criteria); and thekind of market circumstances being operated in (institutionalcriteria). While technical criteria are relatively well-researched,there is little theoretically informed work on the connectionbetween country context and selection of property appraisalmethods. The book starts with an examination of current mass propertyappraisal practices, presenting case studies from widely differingmarkets - from the American and Dutch, where regression-basedmethods have been used successfully for some time; to the EasternEuropean and other emerging economies, where limitations have to becompensated by focusing on the modelling assumptions. The second part of the book looks at sophisticated modellingapproaches, some of which represent combinations of elements fromtwo or more techniques. Whatever the exact modelling approach, therequirements are always high for the quality of the data andsuitability of the method. In the final section, methods areevaluated and compared according to technical criteria and againstinstitutional contexts.With its exceptionally wide coverage ofvaluation issues, Mass Appraisal Methods: an internationalperspective for property valuers addresses property valuationproblems common to different countries and approaches applicable inboth developed and emerging economies.

Models and Methods in Social Network Analysis, first published in 2005, presents the most important developments in quantitative models and methods for analyzing social network data that have appeared during the 1990s. Intended as a complement to Wasserman and Faust's Social Network Analysis: Methods and Applications, it is a collection of articles by leading methodologists reviewing advances in their particular areas of network methods. Reviewed are advances in network measurement, network sampling, the analysis of centrality, positional analysis or blockmodelling, the analysis of diffusion through networks, the analysis of affiliation or 'two-mode' networks, the theory of random graphs, dependence graphs, exponential families of random graphs, the analysis of longitudinal network data, graphical techniques for exploring network data, and software for the analysis of social networks.

The book brings together experts working in public health and multi-disciplinary areas to present recent issues in statistical methodological development and their applications. This timely book will impact model development and data analyses of public health research across a wide spectrum of analysis. Data and software used in the studies are available for the reader to replicate the models and outcomes. The fifteen chapters range in focus from techniques for dealing with missing data with Bayesian estimation, health surveillance and population definition and implications in applied latent class analysis, to multiple comparison and meta-analysis in public health data. Researchers in biomedical and public health research will find this book to be a useful reference and it can be used in graduate level classes.
