Summary
The aim of education is to provide students an adequate supply of information on the theoretical
procedures applied in research and development of transport, handling and
storage media. Are accentuated by new developments in the field
modeling and design, which allows plastics, ceramics and
other unconventional materials. The exercises are focused on the application system
higher mathematics and completed an independent project to solve the sub-
task. Students gain enough experience in the field of theoretical and practice
information on trends, allowing him to focus on applied
principles of active and independent approach to research and development of new
structural nodes and application of new structural materials. The aim of the course
is to prepare students for independent work in developing innovative
design hub and innovative entrepreneurship. Information obtained
Theory of transport machines are the baseline for a new search
solutions in applied transport.
Learning Outcomes of the Course Unit
The aim of the course is to acquaint students with more general theoretical foundation and the wider context of selected effects applied in the area of transport and process equipment. The course deepens the knowledge of the transported and processed materials, especially bulk materials. Purposefully selected information system enables listeners to separate the creative inputs to industry applications, which are at a high level of innovation and lead for many students sign up for their first inventions. The goal is to support the creative ability of students to deepen their ability to see connections between machines, materials, operation, ergonomics and other complex contexts.
