The Use of Tensograf for Optimization of the Composition of Mortars
Hrbáček, Matěj ; Melichar, Tomáš (referee) ; Žižková, Nikol (advisor)
Bachelor thesis is focused on monitoring of volume changes in concrete composites. Using Czech and foreign literature searches are processed, in which mortars in general are described. Thesis is further concerned with description of polymer-modified mortars and with explanation of polymer-matrix forming mechanisms. The following are noticed volume changes and experimental methods of their investigation. The last part describes in detail the Tensograf TGF-02. Experiment is performed by monitoring the volume changes in polymermodified mortars using Tensograf TGF-02 and it is verified its suitability for the subject matter.

Construction of time-space trajectories from multimodal data
Hrbáček, Matěj ; Skopal, Tomáš (advisor) ; Lokoč, Jakub (referee)
With the growth of public camera recordings and video streams in recent years, there is an increasing need for automatic processing with limited human input. An important part of the process is detecting moving objects in the video and grouping individual detections across video frames into trajectories. This thesis presents a set of algorithms for creating trajectories from object detections while using a configurable analytic model. Presented algorithms are based on the clustering of detections, later even simple trajectories, into complex trajectories by their features, such as a timestamp (frame), bounding rectangle in the video frame and optionally, image crop defined by the bounding rectangle. To present the usage of the generated trajectories, we then introduce methods for further analysis and data extraction. The first method improves the input detections by adding missing detection due to the detector error. The second one is creating a simple semantic description of trajectories to enable further research, such as action analysis or trajectory searching. 1

Theater lighting system control
Hrbáček, Matěj ; Ježek, Pavel (advisor) ; Holan, Tomáš (referee)
In the "Ochotnický soubor Lípa" theater, it is necessary to control custom-made lighting communicating via UDP datagrams. The goal of this theses is to create a system in which it will be possible to control these lights through a computer application. The ObjectsForLights library, created within the system, is portable and serves as a logical basis for user applications. The library contains client and server modules. The system is built centrally, where the server is a common point for communication with both clients and devices. The server and client modules take care of maintaining data for devices, communication with each other. The server is also responsible for direct communication with controlled lights themselves. Computer applications were created on top of the client and server modules, and enable user control of individual devices. Applications provide graphical controls for individual devices corresponding to the type of controlled device, provide ability to assign names to individual devices and create groups of controlled devices. Data for the device can then be saved and retrieved from files. 1
