Software Engineering 2: Specification of Systems and Languages (Texts in Theoretical Computer Science. An EATCS Series)
Format: PDF / Kindle (mobi) / ePub
The art, craft, discipline, logic, practice and science of developing large-scale software products needs a professional base. The textbooks in this three-volume set combine informal, engineeringly sound approaches with the rigor of formal, mathematics-based approaches.
This volume covers the basic principles and techniques of specifying systems and languages. It deals with modelling the semiotics (pragmatics, semantics and syntax of systems and languages), modelling spatial and simple temporal phenomena, and such specialized topics as modularity (incl. UML class diagrams), Petri nets, live sequence charts, statecharts, and temporal logics, including the duration calculus. Finally, the book presents techniques for interpreter and compiler development of functional, imperative, modular and parallel programming languages.
This book is targeted at late undergraduate to early graduate university students, and researchers of programming methodologies. Vol. 1 of this series is a prerequisite text.
Themselves. We say that a tree represents a hierarchy. We may describe the hierarchy by explaining the roots, the branches of a(ny) subtree and the leaves. We may thus liken or "equate" a system (a domain, a set of requirements or a software design) by a tree. We may choose to develop the tree structure from the root towards the leaves (also, colloquially, "in the vernacular", known as "top-down"), or we may choose to develop the tree structure from the leaves towards the root (colloquially known.

Transformation that would be effected by an execution as prescribed from that label (when in any one state) and to the program exit, i.e., to and including the last statement of a program — where we hope that if that statement is a conditional GOTO statement that it itself will eventually lead to a no-GOTO to the target label being effected. Variables of a block denote locations, so labels of a block denote continuations, and these bindings are both kept in the block environment: type LOC, VAL.

They clearly show Landin's canny ability to deal with complicated "phenomena" in elegant ways. Landin handles control by way of a special form of closure, giving a statically scoped form of control, namely in terms of the J operator. Later authors have.
For example, by collision. 1. Provide a definition of what an aircraft position, in the air, is. 2. Provide a type definition of the concept of air traffic. Assume a time interval, from time t s tart to time t e n c [, over which air traffic is defined. 3. Impose suitable constraints on air traffic. 4. Define a function which applies to any air traffic and which yields the first time, after t s tart> at which an aircraft collision occurs, i.e., when their locations "overlap". 5. Define another.
