Open languages are the new class of formal languages proposed by the author. A language of this class combines the grammar of an object-oriented programming language with the universality of a natural language. The open language allows the creation of a monolingual communication environment where it can be used in a wide range of communication processes requiring explicit information, i.e. programming, documenting of software and hardware, specification of various standards, tasks' setting, presentation of various kinds of knowledge, etc.

Design patterns books have been gaining popularity since languages like Java and C++ first became widely used. Since Microsoft released its first truly object-oriented language, .NET, software designers from an even broader range of business and programming spheres have been looking for ways to refine and write better code. Many have turned toward design patterns, iterative and AGILE design methodologies, and other more defined ways to improve performance, maintainability, portability, and scalability of code as well as design processes. This book fits into that need in that it can teach people who write software new skills and techniques for improving their existing and new coding efforts.

The class concept is central in OO programming (OOP) to implement abstract data types and enforce encapsulation. Type hierarchy has been regarded as a useful technique for consistency during extension. Yet, the importance of class and type hierarchy extends beyond their technical merits. Specifically, a class classifies objects and a type hierarchy classifies classes. Classification is fundamental to design, and its place in program evolution and programming language structure can be elucidated through formal symmetry models. Symmetry is the interplay between an invariant and the possibility of change. This paper discusses the importance of classification in OOP and shows the connection between classification and symmetry in class and type hierarchies.

A grammar (BNF-type) description of organization theories enables an object-oriented semi-formalized specification of the essential aspects of an organization theory. This specification can be used for the development of simulation models of organizations consisting of intelligent agents. A method for the conceptual analysis and specification of organization theories (CAST) is based on this grammar-based specification. The classical theory of Henri Fayol (1916) has been chosen to demonstrate the CAST method.< >

Network-based provisioning of custom-made and adaptive services offers unlimited opportunities for service development. Examples include ICT-based information, assistance, coordination, and remote monitoring services for senior citizens. Addressing diversity and unpredictable changeability requirements of such service platforms entails novel design solutions. I present Web Pontoon, a method tailored specifically for handling these requirements by a combination of web content management, client-side end-user programming, closed-loop management of object lifecycles, and domain-driven design. Opportunities for massive deployment of relevant applications are being studied.

Improving software development efficiency and reusability of existing programs is an important topic for industrial automation. Recently, modern software paradigms have been introduced into the automation domain such as object-oriented programming using the IEC 61131-3 standard and component-based design based on the IEC 61499 standard. In this paper, another software paradigm - service-oriented architecture is applied to the software design for automation programs. The proposed SOA pattern is based on a multilayered structure with enhanced reusability and flexibility. A case study of water heating system is implemented to prove the concept of SOA paradigm.

Simulation plays a very crucial role to model, study and experiment with any design innovation proposed in the power systems. Since mathematical modeling of power systems leads to tens of thousands of stiff DAEs (differential and algebraic equations), the design of power system simulators involve exercising a trade-off between the simulation speed and modeling accuracy. Lack of efficient and detailed simulators forces the designers to experiment their techniques with small test systems and hence, the results obtained from such experiments may not be representative of the results obtained using real-life power systems. In this paper, we present TDPSS, a high speed time domain power system simulator for dynamic security assessment. TDPSS has been designed using object-oriented programming framework, and thus, it is modular and extensible. By offering a variety of models of power system components and fast numerical algorithms, it provides the user with the flexibility to experiment with different design options in an efficient manner. We discuss the design of TDPSS to give insights into the simulation infrastructure and also discuss the areas where TDPSS can be extended for parallel contingency analysis. We also validate it against the commercial power system simulators, namely PSSE and DSA Tools. Further, we compare the simulation speed of TPDSS for different numerical algorithms. The results have shown that TDPSS is accurate and also outperforms the commonly used commercial simulator PSSE in terms of its computational efficiency.
