Zonnon
Zonnon is a general purpose programming language in the line or family of the preceding languages Pascal, Modula, and Oberon. Jürg Gutknecht is the author. Its conceptual model is based on objects, definitions, implementations, and modules. Its computing model is concurrent, based on active objects which interact via syntax controlled dialogs. The language is being developed at ETH Zürich Institute for Computer Systems by Professor Jürg Gutknecht. Zonnon introduces the concept of 'active objects' which are used to represent real world concurrent objects within computer programs. The Zonnon Language Report was written by Brian Kirk (director at Robinsons Associates), and David Lightfoot ( Oxford Brookes University) working with Gutknecht (ETH, Zürich) and Dr. Eugene Zueff (Евгений Зуев) (Moscow State University). The first book about Zonnon was published by the N. I. Lobachevsky State University of Nizhny Novgorod (a.k.a., Nizhni Novgorod State University).

Oberon (programming Language)
Oberon is a general-purpose programming language first published in 1987 by Niklaus Wirth and the latest member of the Wirthian family of ALGOL-like languages (Euler, ALGOL W, Pascal, Modula, and Modula-2). Oberon was the result of a concentrated effort to increase the power of Modula-2, the direct successor of Pascal, and simultaneously to reduce its complexity. Its principal new feature is the concept of type extension of record types. It permits constructing new data types on the basis of existing ones and to relate them, deviating from the dogma of strictly static typing of data. Type extension is Wirth's way of inheritance reflecting the viewpoint of the parent site. Oberon was developed as part of the implementation of an operating system, also named Oberon at ETH Zurich in Switzerland. The name is from the moon of the planet Uranus, named Oberon (moon), Oberon. Oberon is still maintained by Wirth and the latest Project Oberon compiler update is dated 6 March 2020. Design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jürg Gutknecht
Jürg Gutknecht (born 3 January 1949 in Bülach) is a Swiss computer scientist. He developed, with Niklaus Wirth, the programming language Oberon and the corresponding operating system Oberon. Biography Jürg Gutknecht was full professor in the computer science department at the Eidgenössische Technische Hochschule ( ETH Zurich) until April 2014. From 1967 to 1970, he was a member of the real-time computing system programming group at Swissair. Then he studied mathematics at the ETH and worked in parallel at International Business Machines ( IBM) as a student employee. In 1978, he received his Doctor of Philosophy (Ph.D.) in mathematics. He joined Niklaus Wirth's research team in 1981, working on the Lilith computer and Modula-2. After a sabbatical at PARC in 1984–1985, he developed, conjointly with Wirth, the Oberon operating system based on the Oberon language.

Imperative Programming
In computer science, imperative programming is a programming paradigm of software that uses statements that change a program's state. In much the same way that the imperative mood in natural languages expresses commands, an imperative program consists of commands for the computer to perform. Imperative programming focuses on describing ''how'' a program operates step by step, rather than on high-level descriptions of its expected results. The term is often used in contrast to declarative programming, which focuses on ''what'' the program should accomplish without specifying all the details of ''how'' the program should achieve the result. Imperative and procedural programming Procedural programming is a type of imperative programming in which the program is built from one or more procedures (also termed subroutines or functions). The terms are often used as synonyms, but the use of procedures has a dramatic effect on how imperative programs appear and how they are construct ...

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few ...

Novosibirsk State University
Novosibirsk State University is a public research university located in Novosibirsk, Russia. The university was founded in 1958, on the principles of integration of education and science, early involvement of students with research activities and the engagement of leading scientists in its teaching programmes. As of 2022, Novosibirsk State University had 246th place in the rating of the QS World University Rankings, and was ranked #503 in the world by '' U.S. News & World Report'', and #801 in the world by World University Rankings by ''Times Higher Education''.

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...

Abstract Data Type
In computer science, an abstract data type (ADT) is a mathematical model for data types. An abstract data type is defined by its behavior (semantics) from the point of view of a ''user'', of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations. This mathematical model contrasts with data structures, which are concrete representations of data, and are the point of view of an implementer, not a user. Formally, an ADT may be defined as a "class of objects whose logical behavior is defined by a set of values and a set of operations"; this is analogous to an algebraic structure in mathematics. What is meant by "behaviour" varies by author, with the two main types of formal specifications for behavior being ''axiomatic (algebraic) specification'' and an ''abstract model;'' these correspond to axiomatic semantics and operational semantics of an abstract machine, respectively. Some authors also include the comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Object (computer Science)
In computer science, an object can be a variable, a data structure, a function, or a method. As regions of memory, they contain value and are referenced by identifiers. In the object-oriented programming paradigm, ''object'' can be a combination of variables, functions, and data structures; in particular in class-based variations of the paradigm it refers to a particular instance of a class. In the relational model of database management, an object can be a table or column, or an association between data and a database entity (such as relating a person's age to a specific person). Object-based languages An important distinction in programming languages is the difference between an object-oriented language and an object-based language. A language is usually considered object-based if it includes the basic capabilities for an object: identity, properties, and attributes. A language is considered object-oriented if it is object-based and also has the capability of poly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
