If you are familiar with the constellations, then a logical question arises: is it possible to quickly determine the type of starry sky for any day and hour of the year? You can, but for this you need to learn how to use the sky displacement map, in this article we looked at how to use the sky displacement map.

Today data communication is a modern technology that contains a powerful computer processor to exchange information. But brute force attacks are made to break the encryption techniques and these attacks are the main drawbacks of older algorithms. This paper is concerned with the development of a secure messaging system based on cryptographic algorithms that is which is more faster, better immune to attacks, more complex, easy to encrypt and many more advanced security feature included. This project work is designed and developed for a secure messaging both in web and android platforms. The application is well featured and provides encryption/decryption that can protect message from unauthorized access and disclosure over networks. To send message, a recipient or registered user types and encrypts a text message using keyword mono-alphabetic substitution algorithm with a key, selected from key list. The encrypted message is stored in the database and receiver’s inbox with serial number of key (not the value). The receiver, after log into his/her own account, selects the key value and then decrypts the encrypted message with the key to see the original message. With compared to other messaging systems, the proposed secure messaging system can be used for chat, messaging, video conferencing and real time file sharing in both web and android platforms.

In this article, a model for managing the organization of tourism processes has been developed. The algorithm that displays the process of activity was created on the example of the travel company "Afrosiab". The created algorithm clearly explains the flow of information, the flow of external resources, the flow of customers and the emergence of tourism and the sequence of their interdependence.

In this article, a conceptual model of the organization of tourism processes has been created. An overview of the client part of the web system in the organization of tourism processes is presented. When modeling tourism processes, special attention is paid to the placement and digitization of information and hotel web pages, access to which is carried out with a special login and password.

Some difficulties arise in the processing of images obtained as a result of astronomical observations. We will be able to use several methods and programs (IRAF, Maxim DL) for image processing or astrometry and photometry. In this article, we reviewed the method of astrometry of images obtained from astronomical observations using Maxim DL.

The article establishes for the first time a systematic study of sulfur-containing alkaloids of 4 plant species of the genera Dipthycocarpus and Crambe of the Cruciferae family, including the development of schemes for isolating and separating the sum of bases, identifying known and proving the structure of new alkaloids. As a result of the chemical study of plants, 22 bases were identified, of which 6 are known, 16 are new, for which the structure has been proven.
