object-oriented programming

Розглянуто застосування фрактальної геометрії для захисту зображень. Рекоменду- ється метод, який призначений для побудови зображення за допомогою кривої Гільберта та інших фракталів. На основі цього методу розроблено відповідне програмне забезпечення.

We consider the application of fractal geometry to protect the images. We advise the method that is for constructing images using Hilbert curve and other fractals. Basing on this methods, there was developed appropriate software.

The article develops a mathematical model of non-isothermal moisture transfer and viscoelastic deformation of wood during drying, which takes into account the anisotropy and variability of heat-mechanic characteristics. By finite element method was formulated by the implementation of mathematical models for viscoelasticity with regard to the accumulation of irreversible deformation. By object-oriented analysis is designed and implemented software implementation model in the form of documented classes.

In this article an aspect-oriented programming is considered as a software engineering method for providing maintenance of client-server software systems. The results of redesign system from object-oriented to aspect-oriented by separation of cross-cutting functionality are shown. The relevant code metrics are used to compare object-oriented and aspect-oriented implementations of the system. There have been detected the most and the least effective aspect-oriented implementations of functionality of the client-server system.
