In this paper, description of a concept of cloud Storage age is offered. One of the most practical methods of storing required information to cloud storage is also considered. Method of creating screenshots is proposed. Theoretical research is carried out and there are justified advantages and disadvantages of different methods of storing information in social networks. The best technique of creating screenshots has been practically implemented. Problems that might come up while working with approach given in this article and its solutions are stipulated. There is analyzed a necessity of setting a zoom parameter which is to transfer after transmitting size value of the picture in social networks. In the article the parameter that specifies the width of the final image and clearly affects the quality of the image is also considered. There is analyzed the effectiveness of creating an information system that saves time for such information processes as tracking the photo and its comments. In the paper the task of changing bets, which are not immediately fixed in social networks is optimized. Also there is implemented in practice a scalability problem of information processes in social networks. In the article a separation of the script is also put into practice. One part of which directly performs the request of image and downloads it to cloud storage. With help of another part the information process is transmitted on the photo where the user identifies.

In this paper theoretic aspects of machine learning system in the field of computer vision is considered. There are presented methods of behavior analysis. There are offered tasks and problems associated with building systems using machine learning algorithm. The paper provides signs of problems that can be solved by using machine learning algorithms There is demonstrated step by step construction of computer vision system. The paper provides the algorithm of solving the problem of binary (two classes) classification for demonstration the machine learning algorithm possibilities in image recognition field, which can recognize the gender of the person on the photo. Aspects related to the search of data processing are also considered. There is analyzed the search of optimal parameters for algorithms. An interpretation of results in machine learning algorithm is provided. Binarization methods in machine learning algorithm are offered. There is analyzed the technology for improving the accuracy of machine learning algorithm. There are proposed ways to improve computer vision system in neural systems. Also there are analyzed large software modules that work using machine learning systems. The article provides prospects of powerful information technologies, which are necessary for the proper data selection in learning and configuration of feature extraction algorithm to create a computer vision system.

The aim of this article is to describe the application of the Generic Mapping Tools and other freely available open source packages for operational graphical presentation of environmental data. A general approach to development of such data products is outlined. NetCDF Operators and Climate Data Operators are employed for pre-processing of data. Scripts for map image creation make use of the Generic Mapping Tools, followed by conversion of the GMT-created PostScript to PNG for raster image export and display on a client browser. GMT programs take their parameters from command line parameters, so it can be easily called from shell scripts or pipes. The example scripts were written in Bash on Linux, but can also be developed in any other programming language. The processing in GMT is fast and reliable, so it may also be used for dynamic creation of products.

Celem niniejszego artykułu jest opisanie zastosowania pakietu Generic Mapping Tools oraz innego otwartego programowania do operacyjnej prezentacji danych środowiskowych. Przedstawiono sposób podejścia do opracowania tego typu produktów. Do wstępnego przetwarzania danych zastosowano pakiety NetCDF Operators oraz Climate Data Operators. Skrypty tworzące mapy wykorzystują pakiet Generic Mapping Tools, a następnie dokonują konwersji z formatu PostScript do formatu PNG w celu wyświetlenia mapy w przeglądarce internetowej. Programy pakietu GMT przyjmują wszystkie parametry z wiersza poleceń, toteż mogą być wywoływane przez skrypty i potoki. Przykładowe skrypty zostały napisane w języku skryptowym Bash w środowisku Linux, lecz można wykorzystać do tego celu każdy inny język programowania. Przetwarzanie w GMT jest szybkie i niezawodne, toteż może być także użyte do dynamicznego generowania produktów.

Skrypt prof. Mariana Paleja i inż. arch. Zbigniewa Sowińskiego stanowił znaczącą pomoc w nauce geometrii wykreślnej dla studentów Politechniki Śląskiej w latach osiemdziesiątych. Materiały do wykładów, które przygotowujemy obecnie staramy się dopasować do obecnych potrzeb. Wykorzystujemy przy tym współczesne techniki komputerowe, które dają dużo większe niż kiedyś możliwości edycyjne i graficzne.

EN

Professor Marian Palej and Zbigniew Sowiński's university publication was an eminent aid in teaching descriptive geometry for the students of the Silesian Technical University in the 80s. The aids for lectures which we are currently being worked out are adopted for these needs. Up-to-date computer techniques which offer great editing and graphic possibilities are used.
