Provides a synopsis of recent studies concerning certain areas of language theory close to applications. Topics covered in this volume range from image generations and developmental models to combinatorics of words and formal power series, as well as from fractals to computational complexity.

Cazanescu; nondeterministic, probalistic and alternating computations on cellular array models, K. Kristhivasan, M. Mahajan; low-level tradeoffs between reversals and alternations, K Iwama; compositions of codings, D. Derencourt, A. Terlutte; general formal systems, M. Kudlek; rewriting extended regular expressions, V.M. Antimirov, P.D. Mosses; two-dimensional languages and recognizable functions, D. Giammarresi; fractals, dimension and formal languages, W.
