The first book on ABS methods "ABS-Projection Algorithms: Mathematical Techniques for Linear and Nonlinear Algebraic Equations" by J. Abaffy and E. Spedicato was published by Ellis Horwood in 1989. This book was then translated to Russian and Chinese. Chinese researchers made several important applications of ABS methods to optimization and professors Zhang Liwei, Xia Zunquan and Feng Enmin published a monograph on these results under the title "Introduction to ABS methods in Optimization" in Chinese by the Dalian University of Technology Press in 1999. Considering the great number of results and application we feel that it is time to summarize the most important results including the recent ones in two volumes whose subject is the application of ABS methods for solving nonlinear system of equations, twice is enough method for conjugate directions and optimization. It can be used as a second course for advanced master, or PhD students in fields such as operation research, linear and nonlinear algebra. The readers must have a basic knowledge of linear and nonlinear algebra and mathematical programming.

What brings people to today's Berlin, what makes them stay?For some, the city is a place of refuge, from war and persecution, bigotry or boredom. For others, it's the history or the nightlife or the broad green spaces that attract them - or haunt them. And a few are just born here. How do they cope with the pressure, with housing shortages, racism, club queues, bicycle thefts, shitty jobs, with home catching up on them?Berlin Babel presents fourteen short stories by writers originating from Syria, Turkey, China, the UK, the US, the Netherlands, Spain, Russia, Germany, Italy and India. From Arabic to Italian to Yiddish, the stories are beautifully translated from eight different languages.The selection captures life in Berlin with all its despairs and joys. This first ever international anthology of contemporary writing on the city unites a wide range of perspectives. For all those who love the city, and for anyone curious to discover it.
