Abstract data types in programming
|
|
Annotation: The article discusses various aspects of abstract data types (ADT) in programming. Awareness of the concept of ADT in the mid 70s of last century led to a number of papers on the theory of programming. The concept of abstract data types at the moment is one of the most popular abstraction mechanism used by developers to write software. The paper deals with the basics of the mathematical theory that describes the abstract data types as algebraic systems. On the basis of ADT’s signatures are constructed so-called initial algebra – the syntactic representation of an ADT entities. An initial algebra can be used to verify the correctness of the code.

Constructor of PPM codecs
|
|
Annotation: The paper proposes the implementation of a family of PPM compressors as a customizable set of C++ templates. It's possible to construct PPM codecs using these templates that can support context model orders from the 1st to the 10th inclusive with or without memory restriction. The various known methods of escape code calculation are analyzed in this paper including a new original method proposed by the author. This family of PPM compressors supports the different methods of compression improvement such as LOE, symbols exclusion, extra weighting during initialization and others. The possibility to include any other additional methods to improve the compression is also described.

Creation and support Silverlight application with access throw ISA server and Load Balance System by HTTP and HTTPS protocols
|
|
Annotation: The life cycle of any application consists of the design, development, implementation, delivery and support. Usual situation is when application work in a development environment and testing environment, but does not work or partially work on customer production environment. This article describes an approach that allows minimizing the problem of support for silverlight applications using different proxy servers such as ISA server and Load Balance System using HTTP or HTTPS protocols.
