Nonlinear substitutions or S-boxes are important cryptographic primitives of modern symmetric ciphers. They designed to complicate the plaintext-ciphertext dependency. According ideas, S-box should be bijective, have high nonlinearity and algebraic immunity, low delta uniformity, linear redundancy. These criteria directly affect strength ciphers, providing resistance statistical, linear, algebraic, differential, other cryptanalysis techniques. Many researchers used various heuristic search...
This paper deal with the actual task of semantic analysis for information and communication threats detection online service users. The increasing popularity new Internet technology trends within common social areas create Therefore, generating adaptation to existing identification methods all dangerous are crucial tasks. Identification those allows determining ways their avoiding. computer lingual content, users' accounts personal data authentication, consolidation tracks behavioral models...

Special attention paid applied leadership style school leaders, and existence associations between leaders’ teachers’ behaviour schools. Organizational was measured standardized OCDQ-RS adapted conditions Slovak educational environment sample 474 schoolteachers. scale measures five dimensions: Supportive principal behaviour; Directive Engaged...
The analysis of Big data technologies was provided. An example MapReduce paradigm application, uploading big volumes data, processing and analyzing unstructured information its distribution into the clustered database article summarizes concept "big data". Examples methods for working with arrays are given. parallel system Resilient Distributed Datasets (RDD) is organized. class basic operations realized: con-nection, table creation, getting in line id, returning all elements database,...
This research analyses the non-academic factors in order to predict qualifying test results of applicants software engineering training program. Huge interest IT industry Ukraine requires highly adaptive learning methods education. Discovering that influence academic performance may led a quicker response an needs. It is reflected on on-the-fly adaptation curriculums and more personalized methods. During we reviewed data mining classify candidates' based results. The aimed discover initial...
Wireless Local Area Networks (WLANs) are widely used and their number is constantly increasing. Therefore, the creation of models for detailed study, even more, so automation this process an urgent task. As example research object, we chose Media Access Control (MAC) sublayer Carrier Multiple with Collision Avoidance (CSMA/CA) access scheme. A simplified version state transition diagram was suggested by us, analytical model based on a system differential equations developed. Automation...
The pandemic brought many changes that influenced the education process at universities and Comenius University was not an exception. situation required fast solutions, especially concerning methodological technical support. This resulted in significant upgrades of all systems. article displays views opinions students on online learning during past three academic years, including year 2021 - 2022, when said became optional. We summarize advantages disadvantages according to our compare them...
