In this thesis, I develop an efficient and user-friendly node-based interface to be used in the creation of a particle system in Autodesk Maya. Maya's interface inconsistencies were identified and solutions were designed based on research in a number of fields related to human-computer interaction (HCI) as well as taking design queues from other highly successful 3D programs that employ a node-based interface. This research was used to guide the design of the interface in terms of organizing the data into logical chunks of information, using color to help the user develop working mental models of the system, and also using simple, easy to identify, graphical representations of a particle system. The result is an easy-to-use and intuitive interface that uses a visual-based approach in creating a particle system in Maya. By following guidelines laid out by previous researchers in the field of HCI, the interface should be a less frustrating to use and more organized version of Maya's current interface.

Diploma thesis contains the description of the application developement for management of network entities based on mikrotik devices. In the intro, there is the description of used libraries, also description of API. In the next part of thesis there is programmed part of application backend. This part contains description of individual directories of project, which was written in pycharm. Every directory is described by one file together with UML diagram and table of methods in specific class. In the next part of thesis, there is the description of graphical part of the application and its example on one section of programmed buttons. It contains also output in form of pictures from the application. In the last section, there is tutorial for modules instalation, which are needed to run the application and contains manual testing of application.

This thesis presents an evaluation of various graphical user interface (GUI) technologies for use in the supervision software of CERN’s Beam Interlock System (BIS). The evaluation is necessary because the current GUItechnology used by the supervision software, JavaFX, is no longer supported by Oracle. It also relies on aninternal library that is no longer maintained. Furthermore, a second version of the BIS is being developed, anda GUI is needed that works with BIS and BIS2 in parallel.Which technology is most suitable for the next version of the BIS supervision GUI?This question was answered by gathering user stories from users and experts. Simple proof of concepts weredeveloped for each technology, in order to identify technical limitations and register the development time. Theuser stories relevant to the choice of technology were listed, and each technology received points depending onwhether they were able to fulfill the requirement or not.Furthermore, in order to evaluate the ease of use, wireframes were created based on some of the user stories.These were qualitatively evaluated with stakeholders, which produced feedback that may be used for furtherdevelopment.Out of the four technologies evaluated, PyQt scored 6, ACW scored 4, WRAP scored 6 and Grafana scored3. WRAP and Grafana were discarded as viable options, since they were not able to fulfill hard requirements.ACW scored lower because it is web based and comes with a bigger maintenance overhead. / <p>This thesis was done as a part of a technical studentship at CERN.</p>
