After reviewing recent research in Graph Drawings, in this book, author investigated: 1) Novel heuristic algorithms to solve the 1-page and 2-page BCNPs. They obtained the results better than or comparable with existing algorithms. 2) Genetic algorithms for the BCNPs. They obtained better results than the latest heuristic algorithms. 3) Two neural network models for the 1-page and 2-page BCNPs, respectively, and the convergence of the neural network models. Both models obtained good results. Especially, the model for the 2-page BCNP achieved much better performance than the existing model. 4) The complexity of parallel genetic algorithms, and the unified framework of PGA models in the form of function PGA (subpopulation size, cluster size, migration period, topology). 5) Theorems about the 1-page and 2-page BCNs for some kinds of structural graphs. 6) Proximity to the optimal crossing numbers for the evaluation of different algorithms on some kinds of structural graphs, and conjectures of 1-page and 2-page BCNs for some kinds of structural graphs.
This book offers the first study of vision in the works of George Sand. It argues that, rather than rejecting reality in favour of the ideal, Sand integrates physical observation with internal forms of seeing such as the imagination and visionary insights.

Sand has become a very important mineral for the expansion of society. In recent years, demand for sand has increased tremendously. Environmental problems occur when the rate of extraction of sand, gravel and other materials exceeds the rate at which natural processes generate these materials. Because of illegal sand mining, it becomes a global problem and threatening human life in many parts of the world. This book covered the problematic areas from various parts of the world in relation to environmental damage and discussed the suitable controlling measures. The book is useful to the students and researchers of Earth, Biological and Environmental sciences. It is also useful for the Civil engineers, Hydrologists and persons and social service. The book will provide necessary information for creating awareness among the public to check one of the social problems.
This thesis sets out to analyze “Fast Track Networks”, a special kind of city and regional networks and instrument of the European Commission. As there has been no scientific research about the current instrument of Fast Track Networks so far, this thesis fills this research gap. The aim is to find out the special features of Fast Track Networks in comparing them with the concept of city networks. As a basis for this comparison first a literature review of the two different concepts was conducted after which the concepts were compared. To find out if the special features of Fast Track Networks do not only exist in the concept but also in practice Fast Track Network members were polled with the help of a questionnaire. Additionally the European Commission was interviewed. The result of the comparison between the concept and practice of Fast Track Networks was that the special features of the concept can also be found in practice. However, not all Fast Track Networks fulfil all characteristics of the concept. To improve the concept of Fast Track Networks recommendations were given at the end.
This book provides a comprehensive analysis of the impact of the sand dams on the social and economic status of the local inhabitants of Kitui Central Division. More specifically it examines the demographic characteristics of the residents of Kitui Central, it describes the nature and type of sand dams available in the study area. The book also analyses the influence of the sand dams on the socio-cultural aspects of live of the residents. The book also tries to examine the possibility of sand dams being potential alternative sources of livelihood opportunities for the people.Lastly, the book makes recommendations on how to improve the water harvesting strategies in Kitui Central Division. The Book is recommended for policy makers and development agencies seeking to promote development of rural areas through sand dam’s project. Students taking Rural Sociology, Development Concepts and Project Management will find this book appropriate for their course work.
