The paper considers the main processes of evolution and convergence of information and communication technologies, which have a permanent source for creation and introduction of innovations in learning and education. The modern scientific and technological revolution gives new features to all modern activities, including activities in the sphere of education, influencing it and transforming its phases, form and content, and perhaps understanding in general. Consequently, general understandings about the essence of the provision of educational services and their technological support are also being transformed. Note that, according to scientists, convergence is a new determinant of the development of society, and evolution is a multidimensional natural process of development (becoming).

Digital vector maps must be compressed effectively for transmission or storage in Web GIS (geographic information system) and mobile GIS applications. This paper presents a polyline compression method that consists of polyline feature-based hybrid simplification and second derivative-based data compression. Experimental results verify that our method has higher simplification and compression efficiency than conventional methods and produces good quality compressed maps.

This paper presents a verification watermarking applied to healthcare information management. The proposed method uses the whole region based on the public-key cryptograph, which is transformed by the DWT transform to integrity verification. Furthermore, the public-key cryptograph algorithm is used for the embedded watermark image. We adaptively select the upper bit-plane including the LSB parts of each block when the watermark is inserted.

In this paper deals with the problem of modeling customs information and the criterion for controlling its reliability in the process of managing customs clearance of goods is considered. As the main object of the study, the information of the cargo customs declaration, which is submitted to the customs authorities in electronic form for customs clearance of goods, is considered. The main criteria for determining the reliability of customs information, based on the classical methods used by other fields of science, are given.

This paper investigates simple gray level image enhancement technique based on Genetic Algorithms and Local Statistics. The task of GA is to adapt the parameters of local sliding masks over pixels, finding out the best parameters preserving the brightness and possibly preventing the creation of intensity artifacts in the local area of images. The algorithm is controlled by GA as to enhance the contrast and details in the images automatically according to an object fitness criterion. Results obtained in terms of subjective and objective evaluations, show the plausibility of the method suggested here.
