CONTACTLESS PAYMENTS FRAUD DETECTION METHODS AND IS SOCIETY PREPARED TO RESIST: A CASE STUDY

The ability to use contactless payment technologies, non-cash payments and credit card payments is becoming almost an essential requirement for consumers and merchants in today's economic conditions. Different market sectors are rapidly adapting to these technologies and looking for the most convenient, secure, and fastest possible solutions that combine intelligent data processing, security, and business management functions. Millions of debit and credit card holders care about secure payments, the businesses that receive these payments are secure in terms of security, and the operators that process such incoming and outgoing payments are interested in innovative solutions that set them apart from the competition. Amid the COVID-19 pandemic, when e-commerce was growing exponentially, the global market for fraud detection and prevention, currently stands at USD 20.9 billion, and is expected to grow, until 2025 will rise to USD 38.2 billion by the end of the year; holds the market at 12.8 % annually. The US remains the dominant region in this market segment, but European countries are also increasingly investing in fraud prevention and detection solutions, which are growing in demand in Europe due to an increase in cybercrime as well as advanced bots and cyber-attack.

SYNERGY OF LANGUAGE LEARNING AND VIRTUAL LEARNING PLATFORMS IN STUDIES

The paper presents comprehensive study of applicability of various language learning platforms to the development of foreign language that are indicated in the Common European Framework of Reference for Language (CEFR). To carry out the research, a number of language learning platforms that are used as an alternative to Learning Management Systems (such as Moodle) was selected and on their basis a questionnaire was designed. The quantitative research involved faculty students and lecturers of Vilnius College of Technologies and design. The results of the research permitted us to draw a list of recommendations on which language learning platforms are best to be used in EFL classrooms to facilitate the development of foreign language competences

THE POSSIBILITY OF EDUCATIONAL DATA MINING FOR PRACTICAL SKILLS DEVELOPMENT IN LEARNING MANAGEMENT SYSTEM

The paper presents comprehensive study of applicability of Moodle virtual learning environment to the development of practical skills. The quantitative research involved faculty students and  lecturers of Vilnius College of Technologies and Design. Data analysis indicated that currently the most beneficial method to develop practical skills is blended method. This result, however, turned out to be more positive for students than for lecturers, the latter being less willing to employ technology alongside traditional classroom. The article also briefly describes data mining technologies that are often employed to plan study process, as well as depicts data flows and action sequence of the future survey. The study also puts forward recommendations for further research

The ring type piezoelectric actuator generating elliptical movement

A design of ring type piezoelectric actuator generatig elliptical movement is proposed and analyzed in the paper. Elliptical movement is generated at the area of the actuator applying harmonic excitation signals with different phases. Numerical modeling based on finite element method was performed in order to find resonant frequencies and modal shapes of the actuator and to calculate the size of inner and outer radius, ensuring maximum rotation and bending movements under excitation scheme. Results of numerical studies are discussed
