Object Oriented Languages

Prolog is a logic based programming language, and was developed in the early 1970s and is a practical programming language particularly useful for knowledge representation and artificial intelligence (AI) applications. Prolog is different from many common computer languages in that it is not a procedural language (such as Basic, C, or Java). It is an interpreted logic based declarative language and as such has no loops, jumps, type declarations or arrays, and no fixed control constructs. In the past this has led to the impression that Prolog is a restricted language, useful only for highly specialized programming tasks by enthusiasts (Callear, 1994; Krzysztof, 1997). However, this is not the case and modern versions of Prolog are well equipped and versatile, and can be used for any programming task. The latest generations of the language (e.g., Visual Prolog) can also be integrated into more common object oriented languages.

The programming language itself is the focus of this chapter: Fault-tolerance is not embedded in the program (as it is the case e.g. for single-version fault-tolerance), nor around the language (through compilers or translators); on the contrary, faulttolerance is provided through the syntactical structures and the run-time executives of fault-tolerance programming languages. Also in this case a significant part of the complexity of dependability enforcement is moved from each single code to the architecture, in this case the programming language. Many cases exist of fault-tolerance programming languages; this chapter proposes a few of them, considering three cases: Object-oriented languages, functional languages, and hybrid languages. In particular it is discussed the case of Oz, a multi-paradigm programming language that achieves both transparent distribution and translucent failure handling.

Parallel Programming Language

In this paper, SC-expressions are developed, based on automata theory, for specifying synchronization constraints in parallel object-oriented languages. The predecessor of SC-expressions, the synchronization expressions, was introduced in the ParC parallel programming language in the early nineties [19]. However, ParC is not an object-oriented language and also a number of basic features of synchronization expressions are inadequate for object-oriented languages. SC-expressions are developed for object-oriented environment. They are different from synchronization expressions in basic ideas and assumptions. Here we describe the basic ideas of SC-expressions and their applications in object-oriented languages. We also study the problem of inheritance of the SC-expressions.

Hace unos meses Apple presentó un nuevo lenguaje de programación para sus plataformas: Swift. Con Swift, Apple pretende atraer a los programadores de los lenguajes de programación basados en la sintaxis de C++ y darles una mayor abstracción, que con Objective-C, para que sea más fácil programar para las plataformas de Apple. Por estas razones, se hace necesario contrastar lo pretendido por Apple y realizar un estudio del lenguaje de programación a fin de contrastar su objetivo. Para ello, se hicieron dos evaluaciones, una cualitativa y otra cuantitativa, con el propósito de verificar en qué medida Swift es un avance respecto a Objective-C.DThe Future of Apple: Swift Versus Objective-CABSTRACTFew months ago, Apple presented a new programming language: Swift. With Swift, Apple pretends to attract the programmers of the programming languages based on C++ syntax and gives them a higher abstraction than with Objective-C for being easier to programme to Apple’s platforms. For these reasons, it is necessary to contrast what is intended by Apple and do a study of the programming language to ascertain their goal. For this purpose, we did two evaluations, firstly a qualitative evaluation and after, a quantitative evaluation to verify in how much Swift is an advance with respect to Objective-C.Keywords: computer languages, computer programming, functional programming, object oriented programming, programming, software.

Object Oriented Languages

A conceptual framework for object-oriented programming is presented. The framework is independent of specific programming language constructs. It is illustrated how this framework is reflected in an object-oriented language and the language mechanisms are compared with the corresponding elements of other object-oriented languages. Main issues of object-oriented programming are considered on the basis of the framework presented here.

This paper is concerned with the relation between <em>subtyping</em> and <em>subclassing</em> and their influence on programming language design. Traditionally subclassing as introduced by Simula has also been used for defining a hierarchical type system. The type system of a language can be characterized as <em>strong</em> or <em> weak</em> and the type checking mechanism as <em>static</em> or <em>dynamic</em>. Parameterized classes in combination with a hierarchical type-system is an example of a language construct that is known to create complicated type checking situations. In this paper these situations are analyzed and several different solutions are found. It is argued that an approach with a combination of static and dynamic type checking gives a reasonable balance also here. It is also concluded that this approach makes it possible to base the type system on the class/subclass mechanism.

Mobile configurations and wide-area net-works have garnered tremendous interest from both cryptographers and electrical en-gineers in the last several years. In this paper, we disconfirm the analysis of object-oriented languages, which embodies the un-proven principles of artificial intelligence. BOT, our new system for probabilistic mod-els, is the solution to all of these obstacles.

Growing Population

Agriculture is the backbone of human sustenance in this world. With growing population, there is need for increased productivity in agriculture to be able to meet the demands. Diseases can occur on any part of a plant, but in this paper only the symptoms in the fruits of a plant is considered using segmentation algorithm and edge/ sizing detectors. We also looked at image processing using fuzzy logic controller. The system was designed using object oriented analysis and design methodology. It was implemented using MySQL for the database, and PHP programming language. This system will be of great benefit to farmers and will encourage them in investing their resources since crop diseases can be detected and eliminated early.
