This pioneering study/textbook in a crucial area of pure and applied mathematics features worked examples instead of the formulation of general theorems. Extensive coverage of saddle-point method, iteration, and more. 1958 edition.
The de Bruijn graph was defined in 1949 to enumerate the number of closed sequences where each n-tuple appears exactly once as a window in a sequence. Through the years, the graph and its sequences have found numerous applications – in space technology, wireless communication, cryptography, parallel computation, genome assembly, DNA storage, and microbiome research, among others. Sequences and the de Bruijn Graph: Properties, Constructions, and Applications explores the foundations of theoretical mathematical concepts and the important applications to computer science, electrical engineering, and bioinformatics. The book introduces the various concepts, ideas, and techniques associated wit...
'We cannot imagine life now without a mobile phone' is a frequent comment when Africans are asked about mobile phones. They have become part and parcel of the communication landscape in many urban and rural areas of Africa and the growth of mobile telephony is amazing: from 1 in 50 people being users in 2000 to 1 in 3 in 2008. Such growth is impressive but it does not even begin to tell us about the many ways in which mobile phones are being appropriated by Africans and how they are transforming or are being transformed by society in Africa. This volume ventures into such appropriation and mutual shaping. Rich in theoretical innovation and empirical substantiation, it brings together reflections on developments around the mobile phone by scholars of six African countries (Burkina Faso, Cameroon, Ghana, Mali, Sudan and Tanzania) who explore the economic, social and cultural contexts in which the mobile phone is being adopted, adapted and harnessed by mobile Africa.
This book constitutes the post-conference proceedings of the 16th International Conference on Information Security and Cryptology, Inscrypt 2020, held in, China, in December 2020. Due the COVID-19, the conference was held online and physical. The 24 full papers presented together with 8 short papers were carefully reviewed and selected from 79 submissions. The papers presents papers about research advances in all areas of information security, cryptology, and their applications.
Chinese wallpaper has been an important element of western interior decoration for three hundred years. As trade between Europe and China flourished in the seventeenth century, Europeans developed a strong taste for Chinese art and design. The stunningly beautiful wall coverings now known as 'Chinese wallpaper' were developed by Chinese painting workshops in response to western demand. In spite of their spectacular beauty, Chinese wallpapers have not been studied in any depth until relatively recently. This book provides an overview of some of the most significant Chinese wallpapers surviving in the British Isles. Sumptuously illustrated, it shows how these wallpapers became a staple ingredient of high-end interiors while always retaining a touch of the exotic.
Reprinted from Plant and Soil, v.174, nos.1-2 (1995), this volume is devoted to discussions on the role of biological nitrogen fixation (BNF) in agricultural sustainability. Papers presented on BNF in crop forage and tree legumes are augmented with discussion of integrated farming systems involving BNF, soil and N management, and recycling of legume residues. BNF by non-legumes is discussed and attempts to transform cereals into nodulating plants are critically reviewed. Also described are advances in the development of new methodologies to understand symbiotic interactions and to assess N-2 fixation in the field; means of enhancing BNF through plant and soil management; breeding and selection; problems encountered in exploiting BNF under farmers' field conditions; and promising approaches to improve BNF exploitation.

This book introduces several remarkable new probabilistic objects that combine spatial motion with a continuous branching phenomenon and are closely related to certain semilinear partial differential equations (PDE). The Brownian snake approach is used to give a powerful representation of superprocesses and also to investigate connections between superprocesses and PDEs. These are notable because almost every important probabilistic question corresponds to a significant analytic problem.
Bacteria in various habitats are subject to continuously changing environmental conditions, such as nutrient deprivation, heat and cold stress, UV radiation, oxidative stress, dessication, acid stress, nitrosative stress, cell envelope stress, heavy metal exposure, osmotic stress, and others. In order to survive, they have to respond to these conditions by adapting their physiology through sometimes drastic changes in gene expression. In addition they may adapt by changing their morphology, forming biofilms, fruiting bodies or spores, filaments, Viable But Not Culturable (VBNC) cells or moving away from stress compounds via chemotaxis. Changes in gene expression constitute the main component...
The Rhizobiaceae, Molecular Biology of Model Plant-Associated Bacteria. This book gives a comprehensive overview on our present molecular biological knowledge about the Rhizobiaceae, which currently can be called the best-studied family of soil bacteria. For many centuries they have attracted the attention of scientists because of their capacity to associate with plants and as a consequence also to specifically modify plant development. Some of these associations are beneficial for the plant, as is the case for the Rhizobiaceae subgroups collectively called rhizobia, which are able to fix nitrogen in a symbiosis with the plant hosts. This symbiosis results in the fonnation of root or stem no...
This volume collects the proceedings of the International Conference on Recent Developments in Mathematics (ICRDM), held at Canadian University Dubai, UAE, in August 2022. This is the second of two volumes, with this volume focusing on more applied topics, particularly mathematical modeling and scientific computing, and the first covering recent advances in algebra and analysis. Each chapter identifies existing research problems, the techniques needed to solve them, and a thorough analysis of the obtained results. Advances in Mathematical Modeling and Scientific Computing will appeal to a range of postgraduate students, researchers, and industry professionals interested in exploring recent advancements in applied mathematics.
