The application of fundamental, theoretical and methodological, scientific and professional, and professional and applicative knowledge and methods in solving concrete problems within the selected research field. Researching the literature, students are introduced to the latest knowledge in research field, to methods for solving similar or new problems and with scientific approaches in their solving. The objective of students` activity within this segment of research is to acquire necessary experience in solving complex scientific and research problems from the field of the study programme.

Enabling students to achieve scientific competencies and academic skills. Development of creative abilities, as well as mastering of specific practical skills in the subject matter of the study programme. Enabling students to independently solve theoretical and practical problems, to understand and to use contemporary knowledge, the ability to follow contemporary achievements, independent and creative action, connecting knowledge from various fields and its application, solving problems using scientific methods, performing numerical simulations and experimental research, presentation and discussion of research results, communication at the professional level in writing and presenting scientific research results.

Search and analysis of scientific and research results. Planning and performing numerical simulations and experimental research. Acquisition, processing, presentation and discussion of research results. Writing, publishing and presenting the scientific-research results from the field of the doctoral thesis.

The student, in consultation with the supervisor, selects the research topic. For the chosen topic, supervisor delivers research plan to the student. The student is obliged to make the work within the given subject using the recommended literature. During the development, the supervisor can give additional instructions to the student, refer him to specific literature, and further guide him. In order to successfully carry out the research, the student conducts consultations with the mentor and with other teachers dealing with the research topic. Within the given topic, the student performs an analysis of previous research, identifies the problems and disadvantages of previous research, defines the objectives of his research, and carries out numerical simulations or experimental research. Student presents the research results in the form of the project, and by publishing the paper in international journal with impact factor (SCI/SCIe).
