Abstract In this work we have used image retrieval process for the processing of images in the spatial similarity of the extended objects. A new system is introduced in this work for the spatial location of the objects in the images. For this work we have deployed the geomagnetic approximation. We can able to improve the efforts for creating an enhanced... In this work we have used image retrieval process for the processing of images in the spatial similarity of the extended objects. A new system is introduced in this work for the spatial location of the objects in the images. For this work we have deployed the geomagnetic approximation. We can able to improve the efforts for creating an enhanced system for image processing and retrieval from the spatial databases. Read More Read Less

Abstract We have developed subject based software tools that can assist in the software development process. This work can lead to the process of software development is a way to increase both the effectiveness of teaching SE and the effectiveness of the software engineer’s work. We have used this system in the “Software Engineering” course labs at Varna. This new systems... We have developed subject based software tools that can assist in the software development process. This work can lead to the process of software development is a way to increase both the effectiveness of teaching SE and the effectiveness of the software engineer’s work. We have used this system in the “Software Engineering” course labs at Varna. This new systems can able to draw the attention on both the use of software tools in all phases of software development on as well on the tools development. An open for future development package of software tools is developed for this case; its current structure is discussed in the paper. Read More Read Less

Abstract We in this work detailed the various text encryption programs. These programs used many systems with different keys to encrypt and decode the encrypted text. However, a large number of them have varied efficacy in the relation between output and input data, i.e. encrypted and original data. This includes the documents which are adjusted to different text document, which includes... We in this work detailed the various text encryption programs. These programs used many systems with different keys to encrypt and decode the encrypted text. However, a large number of them have varied efficacy in the relation between output and input data, i.e. encrypted and original data. This includes the documents which are adjusted to different text document, which includes various languages and scripts as well as multilingual documents, too. The results are able to analyse using various metrics of the problems on the example of 5 different text encryption programs. The experimental outcome documented the meaningful differences between different encryption programs, which were under research process. Read More Read Less
