VariCAD is a 3D/2D CAD system for mechanical engineering. In addition to standard tools for 3D modeling and 2D drafting, the CAD system provides support for parameters and geometric constraints, tools for shells, pipelines, sheet metal unbending and crash tests, assembly support, libraries of standard mechanical parts (ANSI, DIN) and symbols, mechanical part calculations and tools for working with bills of materials (BOM) and title blocks. VariCAD supports STEP, STL, IGES, DWG and DXF file formats. The comprehensive CAD software enables designers to quickly create, evaluate, and modify their models. It is compact, fast, easy to use, and provides everything one needs for mechanical design. The CAD system is sold "fully loaded", including all features and functions, for one affordable price.

One engineering system for all SIMATIC Controllers STEP 7 Professional is suitable for configuring and programming the SIMATIC Controllers S7-1200, S7-300, S7-400, and WinAC for PC-based control. SIMATIC WinCC Basic is also included for simple visualization tasks with the SIMATIC Basic Panels. The supplied block library contains a series of technology functions including a PID control. The familiar optional packages S7-SCL, S7-Graph, S7-PLCSim, DocPro and Teleservice from STEP 7 V5.5 are already integrated into STEP 7 Professional V11 and do not require any additional licenses. Registered users of the STEP 7 Professional Software Update Service automatically receive SIMATIC STEP 7 Professional V11.

This volume is an introduction to nonlinear waves and soliton theory in the special environment of compact spaces such a closed curves and surfaces and other domain contours. It assumes familiarity with basic soliton theory and nonlinear dynamical systems. The first part of the book introduces the mathematical concept required for treating the manifolds considered, providing relevant notions from topology and differential geometry. An introduction to the theory of motion of curves and surfaces - as part of the emerging field of contour dynamics - is given. The second and third parts discuss the modeling of various physical solitons on compact systems, such as filaments, loops and drops made of almost incompressible materials thereby intersecting with a large number of physical disciplines from hydrodynamics to compact object astrophysics. This book is intended for graduate students and researchers in mathematics, physics and engineering. This new edition has been thoroughly revised, expanded and updated.

This book provides foundations for software specification and formal software development from the perspective of work on algebraic specification, concentrating on developing basic concepts and studying their fundamental properties. These foundations are built on a solid mathematical basis, using elements of universal algebra, category theory and logic, and this mathematical toolbox provides a convenient language for precisely formulating the concepts involved in software specification and development.
