ND FILTRATION WITH DIGITAL CINEMA CAMERAS
Piňos, Matěj ; ŠEC, Martin (advisor) ; HOJDA, Petr (referee)
This thesis concerns the possibilities of neutral density filters which are used on digital cameras. It is focused on the development of filters, information about technological innovations and solutions. Understanding this issue is an important part of the cinematographer's work, as neutral density filters are the most used filters, especially in the exteriors. The theoretical knowledge is used in the practical part of the thesis focused on camera filter testing.
Sensorless position control of solenoid valve
Piňos, Matěj ; Chalupa, Jan (referee) ; Grepl, Robert (advisor)
This thesis deals with position control of movable solenoid core without using a distance sensor. There are several methods of sensorless position estimation presented in theoretical part. The method based on measurement of ripple current is chosen for experiments. Firstly, it is verified by simulations with mathematical model of solenoid. After that, the experiment is created. The goal is position control based on sensorless method.
Draft bolting torque in plastic components
Piňos, Matěj ; Svoboda, Petr (referee) ; Dvořáček, Jiří (advisor)
This bachelor thesis is dealing with problem of screw connections in plastic components. There are universally described screw connections, threads of tapping screws, issue of prestressed bolt connections and ways to make pretension. Knowledge was applied to specific bolt connection (which is in production) to verify the assembly method. The examined connection was put to the destructive test and the test which explores pressure marks on the plastic components. Results were numerically processed and statistically evaluated. The accuracy of current tightening tools was verified too.
